The Apple Watch Series 2 42mm battery life of up to 18 hours.
However, actual usage time will vary greatly depending on individual habits; some users may experience less than a day’s use, while others may enjoy two days.
Actual Apple Watch Series 2 42mm Battery Life Experience:
Regular Use (approx. 18 hours): Under moderate usage, battery life is close to the official 18 hours. For example, one review showed it lasted from 8 AM to 11 PM with 15% battery remaining.
Light Use (approx. 23 hours or longer): Without frequent GPS use, the Apple Watch Series 2 42mm battery life can extend to around 23 hours, with some users reporting up to 2 days.

Apple Watch Series 2 42mm Battery and Factors Affecting Battery Life
Battery Capacity: The 42mm version has a 334mAh battery, an improvement over the original model, ensuring longer battery life.
Main Power Consumption Factors: Built-in GPS and a high-brightness screen are the main power drains.
Tips to ExtendApple Watch Series 2 42mm batteryLife:
Turn on Power Saving Mode when not in use.
Reduce screen on-time and turn off unnecessary background app refreshes and notifications.
When exercising, if precise route isn’t required, consider using your phone’s GPS instead of the watch’s built-in GPS.

SummaryOverall, the Apple Watch Series 2 42mm battery life is sufficient for a full day of normal use. For an older Apple Watch, if you feel the battery isn’t lasting long, it’s likely normal battery aging, and you may consider replacing the Apple Watch Series 2 42mm battery.

According to actual test data, disabling background app refresh can save an average of about 30% of the Apple Watch Series 1 Smart Watch Batteryower. And most importantly—don’t worry, this won’t affect push notifications at all; it simply prevents apps from silently updating and consuming power in the background.
1. How to turn it off? It’s very simple.Open the “Settings” app on your Apple Watch → Go to “General” → Find “Background App Refresh”.
You’ll see a toggle button, below which is a list of all installed apps. Each app can be individually configured to allow or deny background refresh. The most power-efficient way is to turn off the master switch, disabling all apps from refreshing in the background at once.
After turning it off, those weather, news, and health apps that were secretly running in the background will all stop.
2. Actual Apple Watch Series 1 battery test results: From 8 hours to 24 hoursAfter disabling background app refresh for the first time, I specifically conducted a full battery life test:
I removed the watch from the charger at 7 AM, fully charged. I received notifications normally, occasionally checked the time, and raised my wrist to check the time about 20-30 times a day. By 7 AM the next morning, a full 24 hours later, the Apple Watch Series 1 still had 12% Apple Watch Series 1 Smart Watch Batteryremaining.
That means the Apple Watch Series 1’s battery life jumped from 8 hours to 24 hours. Not just 1.5 times, but a full 3 times!
What surprised me even more was that after disabling background refresh, the watch’s operation became even smoother—the processor didn’t need to frequently switch between background tasks and foreground responses, making everyday swiping and app opening significantly faster.
3. Power-saving tips for combined use (the effects are even more amazing)
Enable Low Power Mode: Control Center → Tap Apple Watch Series 1 Battery Percentage → Turn On.Disable Raise to Wake: Settings → Display & Brightness → Turn off Raise to Wake and set the wake-up duration to 15 seconds.
Reduce screen brightness by 1-2 levels: Settings → Display & Brightness → Lower Brightness. This has little impact on daily use but can save a significant amount of Apple Watch Series 1 Smart Watch Batterypower.
Turn off ambient noise detection: On your iPhone, go to Settings → Noise → turn off “Measure Sound”.
Regularly restart to clear cache: Restart your watch every 1-2 weeks to allow the system to clear accumulated temporary files and memory fragmentation.
Enable optimized battery charging for your Apple Watch Series 1: Go to Settings → Battery → Battery Health → turn on “Optimize Battery Charging”. This allows the watch to learn your charging habits and avoid prolonged full charging, thus extending battery life.
The biggest culprit for battery drain on the Apple Watch Series 1 isn’t excessive screen brightness, but the master switch hidden in “General → Background App Refresh”—turning it off won’t affect message reception, and it triples the Apple Watch Series 1 Smart Watch Battery life. Add to that a black watch face, turn off raise-to-wake, lower brightness, and turn off noise detection—who says this old watch can’t perform?

What we know so far:
The Samsung Galaxy Watch 8 series is still a while away from being officially released, but the internet is already full of rumors and leaks about this upcoming flagship smartwatch series. The most interesting rumor at the moment is that Samsung may completely change the design of the Galaxy Watch 8, transforming it from the traditional round design to a more square appearance.

Samsung Galaxy Watch 8 expected specifications:CPU: Exynos W1000 (3nm)RAM: 2GB
Galaxy Watch 8 battery: 300mAh (40mm), 425mAh (44mm)Charging: WirelessStorage: 32GBConnectivity: Bluetooth, LTEShould I wait for the Samsung Galaxy Watch 8?
If you want to stay on the cutting edge of smartwatch technology and don’t mind waiting a few months, the Samsung Galaxy Watch 8 is worth the wait. The Galaxy Watch 8 promises to offer exciting new features, and health-conscious people will love its potential for continuous blood glucose monitoring, especially those with diseases that require such monitoring.

The latest rumors suggest that the Galaxy Watch 8 will come in two different models, which changes the naming rules again. We may see a regular version of the Galaxy Watch 8, and another Galaxy Watch 8 Classic concept version.Recent rumors also suggest that Samsung may abandon the Galaxy Watch Ultra 2 in favor of the aforementioned Galaxy Watch 8 Classic. If the rumors are true, the design of the Galaxy Watch 8 may lean more towards the classic round shape. In terms of size, the Galaxy Watch 8 Classic is rumored to measure approximately 46 x 46.5 x 14.2 mm. Samsung Galaxy Watch 8 Battery
For smartwatches,Samsung Galaxy Watch 8 Battery
Capacity is crucial. One of the most common complaints about these devices is the lack of battery life. While some models and brands prioritize battery life, Samsung’s (and Apple’s) standard smartwatch models still last about a day between charges. We expect the Galaxy Watch 8 to continue this trend, with the battery capacity of both sizes remaining the same as the previous generation: 300 mAh for the smaller 40 mm version and 435 mAh for the 44 mm version. Samsung Galaxy Watch 8 Features and Software
Galaxy Watch said goodbye to Tizen in 2020, and since then, Wear OS and Galaxy UI have been working closely together. Unlike many arranged marriages, this one is the best.

Wear OS has a lot to like, and in the last generation, we got to experience Galaxy AI on Galaxy Watch! We believe that Galaxy Watch 8 will continue this successful collaboration and offer more interesting and useful AI features.

The Huawei Watch 5 is available for the first time in men’s and women’s designs (46mm and 42mm sizes, respectively) and in a variety of material options, including aerospace-grade titanium and 904L stainless steel. True to Huawei’s high-end watches, it has built-in eSIM support. It’s compatible with Android and iOS, but this time it’s powered by Huawei’s latest Hongmeng OS Next platform (version 5.1). Depending on the model, itsBattery life of theHuawei Watch 5 smartwatch Battery
It can last up to 11 days (in power saving mode). The Huawei Watch 5 is powered by the latest Hongmeng OS Next platform and includes all the standard smart features, such as call notifications, music control, calendar reminders, weather, camera remote control, etc. It also supports app downloads, although the current app library seems very limited.

Health and fitness tracking
The Huawei Watch 5 offers more than 100 sports modes, enhanced GPS and offline map functions, and continuous health tracking. The core feature is the X-TAP system, which unlocks fingertip-based SpO2 monitoring, an electrocardiogram (EKG), and even a mini version of Health Glance that assesses 11 body metrics in about a minute. Battery life ranges from 3 to 11 days, depending on the model and usage. The 46mm Watch 5 is officially rated for up to 4.5 days in standard mode. Even if I didn’t set up an eSIM, I think using just this feature would have taken a toll on the battery of the
Huawei Watch 5 smartwatch Battery
With airplane mode enabled (which still allowed me to keep Wi-Fi and Bluetooth on), I think I managed to extend the battery life of the Watch 5 by about 2 days, which makes the battery life of theHuawei Watch 5 smartwatch Batteryeven more impressive. If you want a smartwatch that lasts up to 11 days and still acts like a smartwatch, power saving mode is a good choice, but you’ll need to sacrifice eSIM, X-TAP, and some other less important features.
Battery life is slightly shorter on the 42mm model of the Watch 5.Huawei Watch 5 smartwatch Battery life is around 3 days (up to 5 days with airplane mode on), and up to 7 days in power saving mode.

While the Watch 5 can’t match the GT 5 in terms of battery life, it still outperforms almost every other flagship smartwatch on the market in terms of performance and advanced features. Huawei Watch 5 Voice calls and haptic feedback The Watch 5 is a very good device for making and receiving calls – the speaker is loud and clear enough that the other party can barely hear me as long as I hold the watch not too far away from me.

The Amazfit T-Rex 3 smartwatch is draining battery faster than usual after a recent software update. According to multiple user reports on Reddit, the watch is now draining nearly twice as much battery as usual per day. However, one user has suggested the cause and fix for the problem.
Amazfit T-Rex 3 smartwatch users have reported Amazfit T-Rex 3 smartwatch battery
drain issues. According to several Reddit users, the faster-than-expected battery drain began with the latest update, version 3.4.4.7, which started rolling out to users earlier this month.
Several T-Rex 3 users said that they usually Amazfit T-Rex 3 smartwatch battery
drained 2-7% per day, but after the update, the drain dropped to 5-10%. Reddit user u/Vizzzions said this could be related to the new active heart rate monitoring feature. Some T-Rex 3 customers have found that disabling this tool (found under the Heart Rate app > Settings) does improve the wearable’s Amazfit T-Rex 3 smartwatch battery life.
A member of the Amazfit team has confirmed the issue and asked users to submit feedback accordingly under Device  User Feedback in the Zepp app. However, the company has not indicated when an official fix for the battery drain issue will be released. It is not clear whether Amazfit has paused the phased rollout of software version 3.4.4.7 until it fixes this issue for the T-Rex 3 smartwatch.
