Just when we thought the issues with overheating Samsung batteries had passed, the company has announced a recall of about 10,200 lithium-ion batteries because of overheating, fire, and burn hazards.
The US Consumer Product Safety Commission (CPSC) announced the recall on August 16, 2017, noting that these are batteries that have been placed in refurbished phones.
Samsung Recalls Batteries in Refurbished PhonesCustomers who are using refurbished AT&T Samsung Galaxy Note 4 cell phones distributed as replacement phones through AT&T’s insurance program may be affected. Samsung has determined that some of the recalled SamsungSmartphone Battery batteries are counterfeit and show anomalies that can lead to overheating. The phones were provided as replacement phones between December 2016 and April 2017.
Samsung has advised consumers to stop using the batteries immediately, and to power down their cell phones. Then they should expect to receive by mail from FedEx Supply Chain a free, new replacement battery and a postage paid box to return the recalled battery. Consumers can identify the new, replacement batteries by a green dot that has been affixed to them.
So far, there have been no reports of property damage or injuries related to this recall.
Samsung Recalled One Million Phones in 2016Back in September 2016, the CPSC announced the recall of Samsung Galaxy Note7 smartphones, because they contained lithium-ion batteries that could overheat and catch fire. The phones were sold before the recall date at stores nationwide, including AT&T, Best Buy, Sprint, T-Mobile, US Cellular, and Verizon.
Prior to the recall, Samsung received 92 reports of the batteries overheating, including 26 reports of burns and 55 reports of property damage, including fires in cars and a garage. The recall affected about 1 million units, and Samsung promised free replacements for consumers.
In January 2017, Recode Media reported that after months of investigating, Samsung had concluded that there was nothing wrong with their Galaxy Note7 phones, but instead, they discovered flaws with the batteries themselves. In one, a design flaw caused the electrodes to bend, which could lead to a connection between the positive and negative tabs, causing a short circuit.
In a second battery Samsung obtained from another provider, a manufacturing issue led to a welding defect that prompted the battery to short circuit and ignite.
Manufacturers Responsible for Battery SafetyIt’s not only phones struggling with lithium-ion batteries. Other devices, including e-cigarettes and hoverboards, have been in the news because of overheating-related incidences and injuries. These batteries are popular because they store a lot of energy in a small space , so they work well for powering many different products, but they are naturally vulnerable to short-circuiting and over-charging. They are also filled with a flammable substance that can explode when it gets too hot.
As technology continues to move forward at breakneck speeds, manufacturers must take steps to make sure their batteries are safe. Proper protection Samsung Cell Phone batteries can reduce the risk of short-circuiting and overheating, while increasing resistance to physical abuse.

Recent Developments in Mobile Phone Battery Technology
The importance of mobile phones in the daily lives of human beings can’t be denied. Their prevalence is primarily due to their efficient utility and portability, which is enabled by a compact and strong battery. To satisfy the rising demands of smartphone consumers, its battery technology is continuously evolving. In recent years, there have been numerous advancements in rechargeable batteries for mobile phones leading to increased battery life and efficiency.
A Brief History of Mobile Phone Battery TechnologyMobile phone battery technology has evolved tremendously throughout the years. A research article published in InfoMat (Willey) has presented a thorough overview of the technological evolutions of the battery. As per the research, 1983 was a significant year as it saw the release of Motorola’s DynaTac 8000X, which employed a Ni-Cd battery with a modest 500mAh capacity.
Nickel-Metal Hydride (NiMH) batteries substituted NiCd batteries in the 1990s. NiMH batteries had an improved power density and were more environmentally friendly than NiCd batteries. Nevertheless, NiMH batteries were susceptible to the memory effect, which diminished their efficiency over time.
The transition period between 1998 and 2000 led to the substitution of NiMH batteries with Lithium Ion batteries. The energy density of Li-ion batteries was significantly greater than that of NiMH batteries, and they were immune to the memory effect. Li-ion batteries are the most common form of battery used in mobile phones today.
Solid State Batteries – A Novel Battery InnovationSolid-state batteries have been viewed as prospective future technologies for energy storage mainly due to their improved energy density and enhanced safety when contrasted to commercial operations lithium-ion batteries with liquid electrolytes.
Toyota, Samsung, and BMW are among the businesses that are developing solid-state batteries for cell phones. A United States startup Solid Power is among the top-notch manufacturers of solid-state batteries as well as Sulfide solid electrolytes for smartphones and electric vehicles Their batteries outperform traditional lithium-ion batteries due to the utilization of better-performing electrodes such as high-content silicon and lithium metal, so consumers may expect a 15-35% cost savings at the pack level.
Graphene-Based Batteries for Mobile PhonesGraphene is the 2-dimensional framework of graphite, in which one layer of planar carbon atoms is organized in the form of a honeycomb lattice. Even at absolute zero, graphene is regarded as a semi-metallic material. Graphene has four times the tensile strength of steel, is extremely adaptable, transparent, and an exceptional conductor of heat and electricity due to its bonds. These attributes of graphene make it a suitable material for both mobile phone batteries and supercapacitors.
Huawei, Samsung, and Graphene Flagship, a research project financed by the European Union, are among the corporations working on the development of graphene battery packs for cell phones.
Hydrogen Fuel Cells Based BatteriesThe utilization of hydrogen fuel cells presents a novel technological advancement with the potential to significantly transform the mobile phone battery landscape. These fuel cells function through the combination of hydrogen and oxygen, resulting in the production of water as a byproduct. Such a process renders hydrogen fuel cells an environmentally friendly and proficient energy source.
Various corporations are currently involved in the research and development of hydrogen fuel cells for mobile phones, including Intelligent Energy, a UK-based enterprise that has engineered a fuel cell that can power an iPhone for up to a week without necessitating a recharge. The organization is presently in the process of creating a commercial version of the fuel cell to cater to the mobile phone industry.
Sodium Ion Mobile BatteriesSodium-ion batteries represent an alternative to conventional lithium-ion batteries for energy storage and release, utilizing sodium ions instead. The abundance and comparatively lower cost of sodium compared to lithium render sodium-ion batteries a more cost-effective choice. additionally, sodium -ion batteries demonstrate a higher energy density in comparison to NiMH batteries.
A research article published in the Journal of Physics: Energy has presented an overview of sodium ion mobile batteries. As per the research, Titanium-based oxides are regarded as highly potential and versatile anode materials for sodium batteries, given their affordability, facile processing, and lack of toxicity. These materials exhibit greater safety in comparison to carbon-based anodes due to their elevated operating voltage, which helps prevent the formation of metallic sodium plating.
Notably, a select number of corporations, including Faradion (UK), Tiamat (Europe), Altris AB (Europe), HiNa (China), and Natron Energy (USA), are currently dedicated to the development of sodium batteries.
Novel Thin Film Battery – A Game Changer for Mobile PhonesA company based in Rzeszów is aiming to revolutionize the global market with its latest thin-film battery, which is expected to have a lifespan of up to 68 years. Developed by The Batteries, this cutting-edge technology has already earned the label of ” a game changer” from the industry press, and the company plans to begin large-scale production once construction of their “pilot factory” is complete.
Polish scientists have created a battery that can charge from 0 percent to 100 percent in merely eight minutes, offering an alternative to the conventional lithium-ion batteries which have dominated the market for the past 25 years. The new technology developed in Poland obviates the requirement for supplementary chemical compounds, and as a result, the energy density of the battery has increased by almost twofold to 1,200 Wh/l.
Market Analysis and Future PerspectiveAllied Market Research has published a thorough report focusing on the market analysis and industry forecast of iphone batteries. According to the report, the global market for mobile batteries had a value of $21.2 billion in 2020, and it is anticipated to grow to $38.6 billion by 2030, exhibiting a compound annual growth rate (CAGR) of 6.3% between 2021 and 2030.
The report highlights that the Asia-Pacific region is projected to hold the largest market share, with China, India, and Japan emerging as major players in the mobile battery market. Nevertheless, North America and Europe are also predicted to experience substantial growth, debt to a surge in demand for superior battery technology fueled by the growing popularity of smartphones and other mobile devices.
The future of mobile phone batteries appears bright, with various promising new technologies currently under development. Notably, the advancement of flexible and stretchable batteries is an area of active exploration. Such batteries can be easily integrated into wearable devices and possess the ability to bend and stretch without compromising their functionality. This will facilitate the creation of novel types of wearable devices that are presently unfeasible.
In short, the recent technological innovations in mobile apple phone batterieswill play a crucial role in the further commercialization of smartphones and modern industrial infrastructure.
How to give more juice to your smartphone’s battery
Considering how much smartphones have changed our lives, it is amazing how feeble they are when it comes to battery life . Most people are ready to accept that a smartphone is barely able to make it through one day. As we have all experienced at one point , this is not nearly enough.
As a result, the aftermarket of power alternatives is huge. We analyzed this cluttered market and we want to share some of the best ways to extend the power of your smartphone. Let’s get started
Do you need more power on your smartphone?
A few years back, phones would easily last 4-5 days between charges. Today we moved from phones to Smartphone Battery that barely get us to the evening. The all-powerful apps of the smartphone era, make us weak in the knees and they do so for a reason. The almighty smartphone is able to exchange messages in dozens of ways, manage your bank account s, serve you music on the go, connect with your social circle s, show you the latest news, access scores of addictive games and the list goes on and on. The conundrum here is that the more you can do on your smartphone, the faster it will run down.
So what can you do? Let’s make sure you have a full list of options in front of you.
In order to make this examination of options practical, we will pick up a few popular smartphones. We decided to get one each from iOS, Android and Windows Phone. When we discuss options, we will put links to the products that work with them so that you have access to pictures and specs and make it easier to get similar options for your smartphone.
Here is the list of smartphones battery under consideration in this article and their power specs:
iPhone 6s: battery 1.715 mAh, Lightning connectorNexus 6P: battery 3.450 mAh, USB-C connectorLumia 640: battery 2.500 mAh, Micro-USBOne ability that is conspicuously missing from all the above smartphones is wireless charging. Do not lose hope yet. We will find creative ways s to get this added to the mix.
Chargers, chargers everywhere!The first thing that you may consider for prolonging the battery life of your smartphone, is getting additional chargers. The investment is rather small compared to the price you paid for your smartphone and the bonus of doubling or tripling its use is worth the money.
The key here is to carefully consider where exactly you spend your day (and night!). The usual places, for which you will need additional chargers, are the workplace and your car, assuming that you keep the original charger at home and use it mainly overnight. If you are an avid smartphone user while at home, you may even cons ider having two chargers there: one for the bedroom and another for the living room.
Another scenario is to have a charger in your bag. I have gotten numerous respites in cafes, trains or airports once I found an electrical socket.
smartphone, battery, charger, power, case, solarA notable variation are the docking chargers. These allow an upright position of your smartphone which makes it easier to check on for notifications. Your work desk or your nightstand are the favorite locations for such docks.
The alternative to a full-blown electrical charger is to get a USB cable that plugs into your smartphone and use any computer or any device, for that matter, with a USB port available as the power source.
There are lots of manufacturers that sell chargers. The risk here is that a cheap charger may not charge as fast your smartphone or even damage it in the long run. It is always a good idea to carefully check the reviews left by other buyers to minimize this risk. The chargers produced by the original manufacturers of the smartphone are the safest bet, although they are usually more expensive.
Here are some good power chargers for the smartphones in our list:
iPhone 6s : wall charger, docking charger, car chargerNexus 6P: wall charger + USB-C cable, docking charger, car chargerLumia 640: wall charger, docking charger, car chargerBefore we close this topic, we need to say a few words about fast charging. This is another area where manufacturers do not manage to converge (yet) to unified standards. Qualcomm Technologies have been promoting standards in this area for a few years with the latest one Quick Charge 3.0 announced this September. Although two of our smartphones are equipped with Qualcomm processors, none of them comply with Quick Charge standards. The Nexus smartphone does come with a fast charge claim, but this is based on Google proprietary devices, which use a special voltage/amperage combination.
What you need to take from this is that fast charging is an important feature that may apply to your smartphone. Qualcomm claims that, in tests with a particular battery, a regular charger achieved 12% in 30 minutes, a Quick Charge 1.0 device 30% and a Quick Charge 2.0 one 60%. Quick Charge 3.0 should be able to deliver more than 80% in the same amount of time.

Apple iPhone 4S Battery Drain: Guessing Game Continues
Waiting on an expected fix from Apple, iPhone 4S users complaining of rapid battery drain are coming up with their own witches’ brews to keep their new handsets from dying before the end of the day. Users started complaining of the poor battery life shortly after the iPhone 4S debuted, but recently the gripes have grown louder.
Home-grown solutions for the iPhone 4S battery dilemma include dropping push e-mail, lowering the screen brightness, turning off calendar notifications, and shutting down Wi-Fi when not in use. Or, to put it another way, iPhone 4S users have discovered sensible battery life management practices.
Apple has yet to officially address the iPhone 4S battery issue, but The Guardian reports that Apple engineers are on the case and contacting users directly to gather more information about the issue. Calls to several Apple Stores for help resulted in suggestions to make a Genius Bar appointment or were directed to an AppleCare hotline with a constant busy signal.
This is not the first time Apple has had to deal with iPhone battery life issues. In 2010, users complained of battery life issues after upgrading to iOS4 and 3GS owners complained of battery issues in 2009 when the device debuted.
DIY Battery LifeCritics and users impatient for an official statement from Apple about the iPhone 4S are trying to solve the battery drain problem on their own. The most popular culprit found so far is a feature in the iPhone 4S’s Location Services that lets a phone discover its time zone automatically. The feature can be switched off by opening the iPhone 4S’s Settings app (the gray cog) and selecting Location Services > System Services (at the very bottom of the screen) > Setting Time Zone.
But that’s not the only solution. Apple’s battery support forum thread on the iPhone 4S battery issue is replete with creative concoctions for battery-saving techniques. This morning, there are 2388 comments and more than 157,000 views on the Apple support forum thread dealing with the iPhone 4S battery life issue.
One user named TonyLukes3 disabled location-based iAds (but left Setting Time Zone on), reduced his screen display brightness to 85 percent, turned off iCloud for Photo Stream and “Documents & Data,” and switched his push e-mail setting to automatically fetch mail every 15 minutes.
WymJamesfound a winning combo by doing a full restore of his iPhone 4S from iTunes, disabling Setting Time Zone, and turning off calendar notifications from Notification Center (Settings > Notifications > Calendar). Echoing similar sentiments, Sam81 turned off calendar notifications for his two exchange accounts and then restarted the device.
Not to be outdone, angrywaiter’s mix of battery saving techniques included switching off “location crap,” calendar notifications, using fetch mail instead of push, and turning off the Wi-Fi radio when not in use. Angrywaiter also dealt with the issue by resetting his phone, which he says he’s done six times over the last four days.
The iPhone 4S batteryIt’s not clear if any of the shared solutions identified the actual cause of the iPhone 4S’s reported battery problems, or if users are simply being turned on to good battery management practices. Lowering your screen brightness, turning off the Wi-Fi radio when not in use, or opting for fetch mail instead of push are common ways to extendiPhone battery life for any phone.

Why does my iPhone power drain so quickly? Here’s how to care for your phone battery
QUESTION: Why do I have occasional days where my iPhone battery is suddenly low on power by midday when I’m not doing anything unusual?
ANSWER: The single biggest issue for every smartphone user is battery life. No matter what type of device you have, it’s going to diminish over time.
How old is it?Whenever I’m asked this question, I always start by focusing on the age of the device. If it’s relatively new, it’s probably related to app usage. If it’s older, it’s probably suffering from diminished battery capacity.
Start by checking the battery’s maximum capacity, which is a measure relative to when it was new or at 100%.
Tap Settings, then Battery, then iPhone Battery Health to get your current status. If it’s under 80%, it may be time to replace the battery. If it’s well above 80%, your issues are probably app usage related.
chemical ageAll rechargeable batteries are considered consumables, meaning there’s a finite limit to their usefulness. As time goes on, the physical age isn’t as important as the chemical age of the battery, which is primarily determined by charge cycles and how it’s been cared for .
Charge cycles
Apple’s guideline for battery lifespan is based on 500 complete charge cycles. A charge cycle is when you’ve discharged 100% of the battery’s capacity, but not necessarily in one day. For instance, if your battery level is at 50% when you recharge on two consecutive days, that would represent one charge cycle. If you are down to 25% every day when you charge, you’re using just over five charge cycles a week.
After 500 charge cycles, your battery will likely be at or near 80% capacity. For most users, that’s two to three years of regular usage.
Temperature’s impactOne of the easiest ways to quickly increase the chemical age of your battery is through exposure to high ambient temperatures.
Temperatures above 95 degrees can permanently damage the battery’s capacity, which can be a constant challenge if you live in a warm climate.
Another big thing to avoid is charging your phone when it’s hot, which can further damage the battery.
More from Ken Colburn:Here are 6 free alternatives to Microsoft Office
Your app usageWhich apps you use and how you use them can have a big impact on daily battery life. Apple makes it easy to see this by going to Settings, then Battery and scrolling down to the list of apps by battery usage.
The default is “Last 24 Hours,” but you’ll better understand your regular usage patterns by tapping “Last 10 Days.”
The app that uses the most battery power will be at the top of the list along with the percentage of iphone battery consumption. This should reflect the apps you use the most, but there’s more helpful information available if you tap the “Show activity” option.
This will give you more details, including how many hours and minutes you’ve used the app and how much of that time was in the background.
If the background usage is very high, you should start manually shutting down those apps when you aren’t using them.
Battery replacement
If your capacity is below 80%, Apple provides a relatively affordable replacement option for most current iPhone models ranging between $89 to $99. To get an estimate on your exact device

Undercharged: iPhone 14 owners complain about lower battery endurance
Owners of the iPhone 14 and iPhone 14 Pro are complaining about battery health — but it’s not at all clear yet if this is an actual issue. Apple Insider looks at the data.Reports in August started to surface about battery issues for the current-gen iPhone 14 and the iPhone 14 Pro, with claims that the battery is degrading far quicker than it should be.
According to the various complaints, if you check the iphone Battery Health & Charging section under Battery in the Settings app, the Maximum Capacity figure is a lot lower than people want it to be. While you could easily expect that the maximum capacity will go down over time, it’s eroding a little too fast for some.Is there an iPhone 14 battery problem?A vocal group of iPhone 14 and iPhone 14 Pro users have raised issues with the Maximum Capacity number, claiming that its dropping at a far faster rate than they would want. These complaints have surfaced on social media, and over the summer, have become more prominent.
In July, Apple Track’s Sam Kohl pointed out via X that the capacity of his iPhone 14 Pro after less than a year of ownership is at 90%, deeming the number to be “actually unacceptable.” John Rettinger passed comment in August, sharing that his iPhone 14 Pro Max, bought at launch, has a capacity of 90% too.
I’ve had my iPhone 14 Pro for LESS than a year this is actually unacceptable pic.twitter.com/rKkvW6Z60v
The Wall Street Journal’s Joanna Stern also chimed in during August, questioning why her iPhone 14 Pro is down to 88%, and an Apple Store Genius said that he personally had already hit 450 charge cycles. By contrast, a three-year-old iPhone 12 Pro held by Stern’s wife was at 80% capacity, and her editor’s two-year-old iPhone 13 Pro was at 90%.
Others have also pointed out low percentages, including The Verge’s Tom Warren at 91% and Max Weinbach tweeting at 89%.
While these are prominent examples, there are many others on social media complaining about the Maximum Capacity for their iPhone 14-era smartphones. Excluding trolling responses, the typical query for those affected by this phenomenon is for a battery that’s mid to low-90’s in percent, or high 80’s.
The general opinion is that the Maximum Capacity shouldn’t be getting close to dipping down below 90% under a year after release. At least, that the percentages shouldn’t be dropping at a rate faster than the batteries of earlier iPhone releases.
Apple’s iPhone 14 battery expectationsApple does attempt to set healthy expectations for the batteries in its devices, as outlined in its Battery Service and Recycling page.
For the iPhone, Apple insists the battery is designed to retain up to 80% of its original capacity after 500 complete charge cycles. By a complete charge cycle, that means effectively depleting the battery then recharging it to full capacity.
Apple’s expectations are for an 80% battery capacity after 500 complete cyclesBy comparison, the Apple Watch, MacBook, and iPad lines are thought to hold on to 80% after 1,000 complete charge cycles, while the iPod does so for 400 cycles.
Apple also includes a clear warning that if you “need to charge your battery more and more frequently, it might be time to service it,” and to do so via Apple or an authorized service provider.
There’s also a one-year warranty for the iPhone, which includes service coverage for a defective battery that’s hit that 80% mark. AppleCare+ will extend this warranty out to two years for iPhones.
For out-of-warranty devices, there’s a battery replacement service.
A common problem?Failure rates for the total number of products manufactured is a bell curve. The early failures are numerically pretty low, with a peak at some point in the middle of the curve, followed by a slow rate as the population declines.
An example of a bell curve graph [Wikimedia]What varies between manufacturers and products is when the peak of failures lies in the timetable of the product. We have it on good authority that Apple has engineered the 80% battery depletion mark average — meaning the peak of the bell curve — at just over two years, and has for at least the last five years of iPhone models.
This means that an about-10% per-year depletion is normal, according to Apple.
For years, we’ve had access to a large amount of service data from within Apple’s repair chain, and iPhone battery replacement rates are included in that set.
We’ve grouped battery replacements into two groups — the iPhone 14 non-Pro models, and the two iPhone 14 Pro models in another group.
Instead of comparing per capita failure rates, we can compare total replacements, given that the total population of iPhones sold in that first year of live is a bit less in 2022 to 2023, than it was in 2021 to 2022.
For the lifetime of the iPhone 14 grouping and iPhone 14 Pro grouping, the number of battery failures, meaning that 80% threshold has been met, or Apple has decided
to replace the battery in a response to a consumer complaint even if not at 80%, is a hair less than it has been in the past. This is consistent with what is believed to be a lower population of iPhone 14 models sold in total, than the iPhone 13 line.
The iPhone 14 Pro family has slightly more failures in total than the iPhone 14 grouping. It’s also believed that the population to date of the iPhone 14 Pro models is higher than that of the iPhone 14.
If there was a massive problem, there would be a giant deviation in the failure quantity, and a corresponding large deviation from that bell curve. To date, there is not that giant deviation in any iPhone 14 or iPhone 14 Pro model.
It’s still early in the device’s life, though, and the iPhone 14 is still on the left side of the bell curve. We’ll revisit this in about six months.
How a battery works, and what’s happeningAppleInsider has previously covered what happens to a battery to cause wear and tear, and how to care for the battery life.
In short, lithium-ion batteries use an anode and a cathode separated by a generally flammable electrolyte, with charged atoms moving from the anode to the cathode through the electrolyte. This process frees electrons, which return to the cathode, completing the circuit.
Recharging effectively reverses this chemical reaction, at the expense of some wear on the battery.
These reactions generate heat and can wear the battery, which eventually degrades the battery to exhaustion in a combination of physical and chemical effects beyond the scope of this article. To users, this wear is represented by a reduction of battery capacity over time. No battery is eternal.Replacing an iPhone battery
As for why the percentage change is faster for some users, this could be down to a number of factors. Most obviously the reason for the decrease could be an increase in battery usage, with intensive apps like games more likely to require higher rates of power consumption in a short space of time. And, that always-on display does draw some power.
A worn battery can be an operational issue, as Apple did introduce safeguards in iOS 10.2.1 that throttled the CPU to minimize the chance of shutdowns from excessive CPU power draws. However, this did lead to multiple class-action lawsuits that resulted in a $500 million settlement.
There is the possibility that, with reduced capacities, iPhone 14 owners may encounter these safeguards far earlier than they may have expected, especially considering the multi-year lifespan of an iPhone 14 Battery in many cases.
How an iPhone battery works and how to manage battery health
Your iPhone uses a lithium-ion battery that degrades over time, but there is little reason to worry about battery health in a new device. Here’s what you need to know about your iPhone’s battery.
Batteries are not mysterious black boxes that power your iPhone, in fact, they are quite simple products compared to the advanced silicon they are powering. The physical nature of batteries mean that they will ultimately wear out and become less useful over time, but device owners don’t need to worry.
Understanding a little bit of the science behind batteries can go a long way in intelligently managing your device’s lifespan. Controversies surrounding iPhone relating to planned obsolescence and expected upgrade cycles can easily be dismissed as hyperbole with a little bit of knowledge.Lithium-ion battery basicsA battery consists of an anode (+) and cathode (-) separated by a generally flammable electrolyte. When a device draws power from the battery, charged lithium ions move from the anode to the cathode through the electrolyte, releasing electrons.
These freed electrons power the device and return to the cathode, creating a complete electrical circuit. The opposite occurs when charging the device — electrons are passed into the anode and move to the cathode.
Without getting too technical, these two chemical reactions are imperfect and introduce heat loss and wear to the battery. The lithium material slowly depletes, oxidization reduces usable surface area, and filaments grow from battery plates. All this leads to cell degradation and eventual battery exhaustion .
There is nothing a user can do to stop this process desolately. Take using fuel in a car, for example, it eventually runs out. However, exhausting a lithium battery takes a great deal of time and can be mitigated somewhat by user and software behaviors .
So, when a new iPhone has a 100% battery rating, it has all of the rated milliamp-hours of power available when fully charged. It also means the battery can provide enough power to the CPU at peak current draw without issue.
Apple says its batteries are designed to retain up to 80% of their original capacity at 500 complete charge cycles. A charge cycle is defined by a complete drain of the battery to zero, followed by a complete charge to 100%.
This expected battery life can vary from user to user. The average user is expected to keep their battery health north of 80% for the first two years with regular use. Hitting 80% within a year is cause for concern, and Apple will replace your battery for free with AppleCare or for a fee without.
Others who use their iPhone constantly and charge their device from near dead to 100% multiple times a day will see their battery degrade faster. Looking at your Screen Time will reveal if you’re unconsciously overusing your device — maybe it’s time to put down your iPhone if TikTok shows multiple hours of use in a short time.
Of course, iPhones are bought to be used. But, like anything, moderation is important, especially if you’re worried about something as physical as battery chemistry.
Ultimately, once the battery degrades below 80% of its original capacity, protections within the operating system will engage to ensure the device doesn’t shut down inadvertently. This throttling can be avoided by having the battery replaced at an Authorized Apple Service Provider.
After the iPhone throttles the processor for the first time to prevent a shutdown, a new toggle will appear in battery settings. This gives users the ability to turn off the throttling feature and allows the processor to draw full current.
However, the device will shut off as soon as the current draw exceeds what the battery can provide. It is highly unadvisable to turn off the throttling feature and can lead to battery damage.
Degraded batteriesBefore iOS 10.2.1 in 2017, the iPhone didn’t do much to account for aging batteries in its software. However, a perfect storm of circumstances set AppleBattery up for user complaints about inadvertent shutdowns in older devices.
Recent devices had more powerful processors, thinner designs, and brighter displays. These factors led to smaller batteries with lower capacities that died faster. A smaller battery also meant a lower peak voltage, which meant aging batteries would dip below peak rated voltages sooner.
Those factors were coupled with more people buying iPhones than ever, then keeping them for longer than expected, which led to more reports of batteries becoming exhausted. Note that the “Plus” models and iPads were not encountering shutdown issues thanks to their larger battery capacities .
Intermittent shutdowns were reported by owners of the iPhone 6, iPhone 6s, and iPhone SE. Users complained that the device would show battery levels of 30% or more then suddenly shut off as if the battery died.
This occurred because these devices’ batteries had been exhausted to the point that they could no longer provide peak power during peak CPU draw. Since there were no other protections in place, the iPhone would sense the CPU power draw exceeding the available current and just shut down to protect the iPhone battery.
Best Practices For A Healthy Smartphone Battery Life
Users are forever in search of the best smartphone that has longer battery life. Gone are the days where batteries are easily replaceable. Today, we have to be conscious of our battery usage to minimize the expensive professional service that comes with smartphones.
Almost all smartphones are equipped with lithium-ion (Li-ion) batteries and while we all use the same type, no battery has the same lifespan. It all depends on our habits and how we use our phones that can determine how long can we keep the health of our smartphone batteries.
Best Practices to keep your Smartphone Battery Healthy
If you have been with your smartphone for more than a year, you might notice that batteries don’t last long compared to when it was brand new. Down the line, many phones can’t make it through a day with a single charge.
There are various ways to extend your phone battery lifespan. You might be familiar with it or it might sound new to you, but here are some best practices you can follow to keep your smartphone battery healthy:
Partial ChargingMost of us are guilty of fully charging our phones out of habit but in reality, it’s bad for the battery. Also, some are using their phones until the battery goes 0 percent before plugging it in, which should be avoided.
The best way to charge your phone and extend its lifespan is to charge it partially and frequently. For example, you can charge it for up to 80% and use it until it goes to 20% before charging it again. With this charging cycle, you can improve your smartphone’s battery life.
Avoid Extreme HeatLi-ion batteries don’t respond well to heat or extreme cold. If you are located in a cold area, its’ best to use thick phone cases that can keep it warm. For hot weather, don’t leave your phone exposed to sunlight. Heat is the worst enemy for Li-on batteries while cold might damage its health temporarily.
It’s best practice not to leave or store your mobile device in an enclosed space where there’s minimum ventilation as it raises the phone’s temperature, especially inside a hot car.
Decrease Screen BrightnessTurning down your screen brightness will save energy. Your smartphone screen is the component that uses battery the most. For iOS and Android devices, it gives you an option to automatically reduce the screen brightness when there’s light, though it still uses a light sensor. It’s advisable to disable auto-brightness.
You probably don’t require the full brightness, so manually setting your screen’s brightness depending on the ambient lighting is best recommended and will save your phone battery life.
Avoid Using Phone While ChargingMost people can’t keep away from their phones because it’s now considered a necessity. However, when it’s charging, it is better to avoid using it. When you use apps that require a large proportion of battery to operate, it’s consuming a lot of energy, thus reducing your battery life in the process.
It can also lead to overheating the device and as mentioned earlier, heat is the worst enemy for Li-on batteries. The best solution is to turn it off while charging, or if it’s really necessary to use it, then keep the workload very light when your phone is plugged in.
Avoid Using Non-Compatible Charging CablesThe most common practice people do is to use a counterfeit or third-party charging cable. You might think that you are saving some money because you bought it for a lower price, but it can seriously harm your smartphone battery.
Accessories that are not manufactured by the original provider are made of cheap materials that don’t work the same way as the original cables. Ensure that you are only using the right charging cables to protect not only your battery but also your smartphones.
Reduce Screen Timeout or Auto-LockSimilar to laptops or computers, your mobile’s screen can automatically turn off if not in use. You can save energy by reducing the screen timeout or auto-lock by 1 minute or even 30 seconds. Both iPhones and Androids have these features and it’s easy to set up.
Check Your AppsAll smartphone apps use power and data even if they are not in use, like Facebook. To extend your battery life, disable the background refresh activities of apps that aren’t crucial and do it regularly. When apps update, some new features are added and might consume more energy, so you’ll notice your battery draining. Make it a bit to monitor apps that consumes power even if you don’t use them.
Nowadays, Lithium-ion battery technology is more understood, but some myths remain in our consciousness. While most of the habit doesn’t severely impact your smartphone’s battery life, the decrease in removable batteries should be a reminder that we need to take precautions to prolong our smartphone’s battery life.
