JBL GO 4 review: Definitely worth the upgrade

JBL GO 4 Bluetooth Speaker In addition to the superficial design changes, including a wider and more comfortable tactile band, a more practical placement and distribution of control elements, the device also features a number of technical improvements. The first thing to mention is the compatibility with the JBL Portable app, through which you can make the necessary adjustments to the five-band equalizer, save battery or monitor its JBL GO 4 Bluetooth Speaker Battery charge level. The Bluetooth version has also been upgraded and features Auracast technology, allowing stereo pairing or wireless connection with multiple supported speakers in party mode. The operating time ,JBL GO 4 Bluetooth Speaker Battery  time has increased from 5 to 7 hours, and if you sacrifice frequency adjustment by turning on the PlaytimeBoost function, you can add another 120 minutes. Thanks to the high coverage that ensures dust and water resistance, the owner can remain completely calm even in the event of an accident in the pool, which also applies if he plans to carry this space-modest companion on outdoor trips in more demanding conditions. The power of the smallest of the JBL wireless speakers is 4.2 W RMS. For its size, it achieves an exceptionally rich and clear sound with the help of a 45mm or 1.75-inch driver (frequency range of 90 Hz to 20 kHz). It is powered by a 3.8V lithium-ion polymer battery with a capacity of 850 mAh, and according to the manufacturer,JBL GO 4 Bluetooth Speaker BatteryThe maximum battery life is 3 hours, with up to 7 hours of playback on a single charge (another 2 hours with PlaytimeBoost turned on). Wireless communication is provided by Bluetooth version 5.3 with A2DP V1.4 and AVRCP V1.6 profiles, while the IP 67 rating prevents the penetration of dust particles and even immersion in 1 meter of water for 30 minutes will not damage the GO 4.
When testing the signal range, I was able to exceed 100 meters in the open garden area, while in the house, only the farthest corner of the bathroom was blocked by the floor, a few doors and metal building elements. Starting from a state where it was turned off due to low JBL GO 4 Bluetooth Speaker Batterythe speaker reached 60% charge after half an hour of non-use, with maximum charging time taking a total of 1 hour and 28 minutes.

The Galaxy Watch 8 gets a key battery health feature that more smartwatches need

New Battery Protection feature in One UI 8 Watch keeps your Galaxy Watch 8 charged at 85% to 90% Samsung’s new Galaxy Watch 8 series introduces a “Battery Protection” feature designed to extend the device’sGalaxy Watch 8 batterylife.
The feature works by stopping charging when the battery reaches 90% and only resuming charging when the battery drops to 85%.
This prevents theGalaxy Watch 8 batteryfrom being 100% full, thus reducing stress and helping to slow long-term battery degradation.
Most people don’t upgrade their smartwatches every year, instead choosing to keep using them until something better comes along or the battery degrades. However, unlike smartphones, most smartwatches don’t offer robust battery protection features, which limits theirSmart Watch Battery Samsunglife. Fortunately, more and more smartwatch manufacturers are starting to roll out these features, with Samsung being the latest to introduce them in its new Galaxy Watch 8 series.
In previous Galaxy Watch models, there were only two options listed under the Charging section of the Settings > Battery menu: Show charging info and Auto-power on. The former controls whether the watch displays the battery level when it’s fully charged, and the latter determines whether the watch automatically powers on when connected to a charger.
While setting up my Galaxy Watch 8 Classic, however, I discovered a third new option called Battery Protection. This new feature stops charging at 90% and resumes charging at 85%. Essentially, this feature keeps the watch’s battery between 85% and 90% of its maximum capacity.
Galaxy Watch 8 batteryProtection settings on the Galaxy Watch 8This feature is important because keeping a lithium-ion battery at 100% state of charge for long periods of time can shorten its lifespan, as a high state of charge puts stress on the battery. As a result, many smartphones offer similar protections, but they typically limit charging to 80%, not 90% like the Galaxy Watch 8 does. Although 80% of the Galaxy Watch 8 battery charging limit is better for battery life, the battery capacity of smartwatches is small, so Samsung may not want to set the charging limit too high to avoid affecting the user experience. In any case, it is good to see that Samsung has finally added a meaningful Galaxy Watch 8 battery protection feature to the Galaxy Watch.

Huawei Watch 4 review: Super smart

The Huawei Watch series has always been the brand’s most sophisticated smartwatch (until the launch of the Watch Ultimate), and offers users the most advanced features of any wearable device. Visually, the Watch 4 has a slimmer design and a mirror-polished stainless steel case. The Watch 4 features a 1.5-inch, 466 x 466 resolution LTPO always-on display that is brighter and clearer than ever. The biggest change is the addition of eSIM functionality to the watch for the first time. The Huawei Watch 4 can use a separate eSIM card, or if you are a Globe user, you can use the eSIM card already in the watch, which continues the series’ impressiveHuawei Watch 4 Batterylife, Huawei promises up to 14 hours of battery life in ultra-long battery life mode and up to 8 days of battery life under normal use

This will allow you to use many of the watch’s advanced features, such as playing music and making calls, without having to carry your phone with you.

The battery capacity and battery life of Huawei Watch 4 series smartwatches (including Watch 4 and Watch 4 Pro) are as follows:

1. Battery capacity

Huawei Watch 4: built-in 536mAhHuawei Watch 4 Battery

2. Huawei Watch 4 Batterylife performance

Typical usage scenarios (turn on heart rate, blood oxygen monitoring, occasional calls, message notifications):

Watch 4: about 3 days Heavy use (frequent calls, GPS sports, eSIM independent networking): about 1-2 days.

Watch 4 will soon support payment using GCash (provided it has a built-in eSIM card) without a mobile phone connection, making it the first wearable device in India to support this feature. In addition, it has all the functions that a good smartwatch should have: it has a variety of health monitoring functions, including reading heart rate, electrocardiogram (ECG), blood oxygen saturation (SpO2), body temperature sensor, stress monitor and breathing checker. This watch has many built-in sensors, and Huawei claims that it can generate a microphysical report for users in 60 seconds.

Amazfit GTR 4 review: The king of budget smartwatches

It’s hard to justify Fitbit when the Amazfit GTR 4 looks better, lasts longer, and does far more than you’d expect. The TR 4 may not win any design awards, but for an affordable watch it looks pretty good (especially compared to previous versions). Like the Garmin and Polar watches, the GTR 4 supports turn-by-turn directions. It’s easy to import your own routes – I used Komoot and Strava. When you’re out for a run, hike, or bike ride, you can enable turn-by-turn directions. It’s also rated to 5ATM for water resistance, which means you can jump into a pool with it. I wore it in the shower and while washing dishes with no issues.

I got about 10 days on a single Amazfit GTR 4 smartwatch battery charge I’m not an ultramarathoner or triathlete, so I can’t vouch for the GPS battery estimates.And that’s just one side of the smartwatch. The GTR 4 also comes with a wealth of health and fitness features. You get in-depth sleep metrics and the ability to set a sleep schedule. It has period tracking, continuous heart rate monitoring, blood oxygen tracking, and stress tracking.
What’s impressive, however, is that the GTR 4 includes multi-band GPS – and at this price point. Multi-band GPS isn’t that common yet, and we’ve only started seeing it on fitness watches in the past year or so. In short, it utilizes both L1 and L5 satellite frequencies to provide more accurate GPS in challenging environments like cities or forests. I can’t think of another smartwatch in this price range that has multi-band GPS. Cheap smartwatches often have longer battery life than expensive ones. Usually, this is because they use dim, low-resolution screens that use less power. This isn’t the case with the GTR 4, but Amazfit claims a battery life of 7 days with heavy use (i.e. multi-band GPS, always-on display, etc.). You’ll get about 14 days with normal use. For endurance athletes, enabling multi-band GPS will get you about 25 hours of continuous use, while regular GPS will get you 44 hours. Bottom line — you’ll get more power than a flagship smartwatch.
 That being said, I was able to get about 10 days of use on a single charge. Half of that time, I had the always-on display turned off and multi-band GPS enabled at all times. During my testing, I logged about 2.5 hours of GPS activity. Some smartwatches and fitness bands useAmazfit GTR 4 Smartwatch Battery
life longer, but with moderate use and an OLED display, 10 days is great. Charging time is not great. It took me about two hours to charge from zero to 100%. This is not the worst, but it stands out as more and more wearables now support fastAmazfit GTR Smartwatch Battery
charging. I am not a fan of proprietary chargers, but again, this is a problem in the smartwatch industry.
Feature OverloadThe GTR 4 has a ton of features. Depending on your needs, it might actually have too many. If I went into every single one, this review would easily be over 2,000 words. No one has time to write that—especially since Amazfit is more than happy to list all of them on its product page. It’s exhaustive.

life, and construction.
The JBL Flip 6 has a burrito-shaped speaker with excellent bass. So, we said in our review:
The upgrade in sound quality in terms of clarity and frequency width is obvious, and if you want richer mids and less treble, for example, you can adjust this in the app. There is indeed more detail. The Flip 6 is also capable of outdoor use, thanks to its impressive IP67 rating for dust and water resistance.
Last but not least, it has up to 12 hours ofJBL Flip 6 bluetooth Speaker Battery life, which means you can enjoy the speaker through a full day of barbecues or pool parties.
A good choice for those who are looking for a solid Bluetooth speaker. The biggest thorn in the side of the Flip 6 is JBL’s five-star Charge 5 – another larger, more powerful portable Bluetooth speaker with longerJBL Flip 6 bluetooth Speaker Battery life (20 hours versus 12 hours), the ability to charge your phone, and a larger sound all mean that the 2022 award-winning Charge 5 is our top pick in a direct comparison.

Apple plans to launch AI battery management mode in iOS 19 to automatically save power

Apple (AAPL) plans to use AI technology to solve the battery life problem of iPhone. According to people familiar with the matter, the company plans to launch an artificial intelligence battery management mode for iOS 19, the iPhone software update to be launched in September.
People familiar with the matter said that the enhancement will analyze how iPhone users use their devices and make adjustments to save energy. In order to create this new technology as part of the Apple Intelligence platform, Apple is collecting battery data from user devices to understand usage trends and predict when the power consumption of certain applications or features should be reduced. People familiar with the matter said that the technology will have a lock screen indicator showing how long it will take to charge the device. Apple (AAPL.US) held a global developer conference at its headquarters in California on Monday and announced the launch of a new visual design language “Liquid Glass”, which will upgrade all iPhone, iPad and Mac operating systems. It is also the first major redesign of the iPhone operating system since 2013. However, there were few artificial intelligence features involved at the conference, only the translation function was incorporated into the system and new tools were added to shortcuts. The advanced version of Siri  AI promised by Apple has not yet appeared, and the market was disappointed. Apple’s stock price fell 1% on Monday. The new system design update, called “Liquid Glass,” includes translucent features such as redesigned notifications and more. Apple says it is more dynamic than previous design languages and will bring greater consistency across all operating systems, including iOS, iPadOS, and macOS. At the same time, Apple will also change the names of all its operating systems, launching iOS 26 instead of iOS 19 this fall. iPadOS 26, watchOS 26, and other systems will follow suit, marking the first time Apple has given its software updates a release year instead of an arbitrary code name. In terms of  AI , Apple has integrated Apple Intelligence into the existing Shortcuts app and updated the visual intelligence feature, which can use the iPhone’s camera to identify objects and events. Visual Intelligence provides an “Ask” button that enables users to ask ChatGPT what’s on their screen. At the same time, the enhanced Image Playground tool released by OpenAI for the next version of iOS is introduced, where users can describe the desired style and ChatGPT will adjust the image. The iPad is undergoing major changes, including a new multitasking system that mimics the Mac. Apple demonstrated the ability to open six apps on the iPad screen at the same time, and supports background tasks, so apps can be switched during video export. Apple (AAPL.US) has an internal release target of launching an upgraded version of Siri  AI in the spring of 2026, hoping to turn things around in the  AI market. Foreign media quoted people familiar with the matter as saying that the Siri team plans to include this important AI upgrade in the iOS 26.4 release. Siri will be able to analyze user profiles and screen operations to provide more accurate and personalized responses. As usual, Apple releases a “.4” update around March each year, such as this year’s iOS 18.4 and last year’s iOS 17.4. Apple reiterated its earlier statement that the Siri upgrade plan will be carried out next year.

Xiaomi Redmi Buds 5 Pro review: Cheap true wireless earbuds with all the features of the big brands?

AirPods Pro? No Redmi Buds 5 Pro. It’s hard not to think of Apple headphones when looking at these new Xiaomi headphones, both in terms of design and in terms of the full range of features they offer given their price.

It’s worth the money: LDAC lossless audio, immersive sound, active noise cancellation, multipoint, IP54 and even dual sensors. The execution still needs to be as good as this feature richness. Since Xiaomi did not include a wireless charging system in this case, the USB-C port will be the only way to charge it. The indicator light on the front shows the Xiaomi Redmi Buds 5 Pro Headphones Battery level and status of the Xiaomi Redmi Buds 5 Pro headphones.

The equalizer brings good sound quality. However, as soon as you press the play button, the smiley face appears again. The sound quality of the Buds 5 Pro is above average for 100 euro headphones. To do this, Xiaomi equipped them with a dual transducer: an 11 mm transducer dedicated to low frequencies and a 10 mm transducer dedicated to the highest frequencies. Finally, Xiaomi announces an impressive 10 hours of battery life for its Buds 5 Pro, thanks to the 54 mAh Xiaomi Redmi Buds 5 Pro Headphones Batteryin each earphone. Note, however, that this is measured without noise cancellation enabled, so these devices lose a strong argument. With ANC enabled, we found an excellent battery life of about 11 hours!

Its charging case is equipped with a 480 mAh Xiaomi Redmi Buds 5 Pro Headphones Batterythat is claimed to be able to fully charge it a little more than three times. Test results It would be an illusion to think that this Buds Pro 5, which costs a minimum of 100 euros, is able to offer quality and features comparable to models of almost 300 euros.

However, Xiaomi has shown some virtuosity in this regard, thanks to good autonomy, consistent sound quality (after equalization) and correct noise cancellation. We lament that the gimmick of lossless sound quality is difficult to really feel and that immersive audio cannot be achieved, but if you do not need these two things, this earphone is a good choice and a bargain.
