Amazfit – Battery Tips

Amazfit watches (GTS, GTR, T-Rex, etc.) are known for long battery life, but heavy tracking and bright animated faces can still drain them faster than normal. Try this:

Turn off or reduce Always-On Display if you do not need it all day.
Lower brightness and set the screen-on time to about 5 seconds.
Disable extra 24/7 health options you do not really use, such as:
- Continuous stress monitoring
- All-day SpO₂
- Sleep breathing quality checks every night
Use a simple built-in watch face instead of a heavy, animated one.
Turn off features like offline voice control or auto workout detection if you rarely use them.
Limit notifications to only the apps that matter to you.

Garmin – Battery Tips

Garmin models like Forerunner, Fēnix, Epix and others have strong battery tools built in. Smart use of these can add many extra hours:

Use Battery Saver or create custom Power Manager profiles for long runs, hikes, or travel days.
Select battery-friendly GPS modes (for example, standard GPS instead of multi-band when you do not need the highest accuracy).
Lower the backlight brightness and reduce how often the backlight turns on with wrist raise or button presses.
Turn off smartphone notifications, music streaming, and Wi-Fi syncing when they are not needed.
Choose simple watch faces and remove faces that refresh every second with complex animations.
Disable unused external sensors or ANT+ accessories when they are not in use.

Huawei Watch – Battery Tips

Huawei Watch and Watch GT models already offer long battery life, but you can often add more days with a few changes:

Switch to Battery saver mode when you only need basic tracking and time.
Reduce or turn off Raise to Wake so the screen does not light up with every tiny movement.
Lower screen brightness and pick darker, simpler watch faces.
Limit continuous heart-rate monitoring, SpO₂ checks, and extra always-on health tests if you just need basic stats.
Remove or disable third-party apps and notifications you no longer use.

General Battery Habits for Any Smartwatch

Avoid draining the watch to 0% every single day; many lithium batteries prefer staying roughly between 20% and 80%.
Keep the charging contacts clean on both the watch and the charging cable.
Install firmware updates when they are available—some updates improve power management.
If battery life suddenly gets much worse, restart both the watch and your phone and check which app or setting changed recently.
If the watch is several years old and will not last even one day with everything optimized, it might be time to contact support or think about an upgrade.

This page is for general educational information only. Always double-check settings with your watch’s latest user manual or official support site for the most accurate instructions.
