How to Make a Smartwatch Battery Last Longer

Practical, model-aware ways to extend smartwatch runtime, from screen and background settings to connectivity, GPS use and battery health.

To make a smartwatch last longer between charges, start by reducing screen activity, background updates and unnecessary wireless connections. Use your watch’s Battery Saver or Low Power mode when its feature trade-offs are acceptable, and limit GPS workouts or music streaming when you need to conserve power. The exact controls depend on the watch model and software version.

Start with your watch model and the biggest power users

Before changing settings, identify the watch model and software version. Menu names and available controls differ across Apple Watch, Google Pixel Watch, Samsung Galaxy Watch and Garmin devices, so don’t assume a path for one generation applies to another.

The practical areas to review are the display, background activity, wireless connections, streaming and GPS-intensive use. Manufacturers do not provide a controlled, cross-brand estimate of how many extra hours any single adjustment will add.

Reduce screen activity

An always-lit display and frequent screen wake-ups can use power. If you can live without the screen staying visible, turn off Always On Display where your watch offers it, or shorten the screen timeout so the display switches off sooner. Google lists a faster screen timeout as a Pixel Watch battery tip; Apple includes an Always On control and disables the feature in Low Power Mode.

On Garmin watches, reducing screen brightness is another option identified by Garmin Support. The setting and its location depend on the model.

Limit background activity and watch-face updates

Review background app refresh, or the equivalent setting on your watch, and disable it for apps that do not need to update when you are not using them. Apple notes that “Refreshing apps in the background can use power.” However, complications on the current watch face may still refresh even after background app refresh is turned off, so consider removing complications you rarely need.

Use power-saving mode when its trade-offs suit you

Battery Saver, Low Power Mode and similar features reduce power use by limiting activity or disabling features. They are useful when getting through the day matters more than having every function available, but their effects vary by watch.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.
  • Apple Watch: Low Power Mode can turn off Always On display, background heart-rate and blood-oxygen measurements, and heart-rate notifications. Some other notifications may be delayed, emergency alerts may not arrive, and some Wi-Fi or cellular connections are limited. See Apple’s watchOS 26 battery guide for the described features.
  • Google Pixel Watch: Battery Saver disables Always-on Display, limits background activity and may delay notifications. Google’s Pixel Watch battery guidance describes the setting and its effects.
  • Samsung Galaxy Watch: Samsung identifies Watch Only mode as an option for extending daily battery life when you are resting or do not need smart functions. It is a more restrictive choice than simply dimming the display; check the instructions for your watch generation in Samsung’s battery-drain troubleshooting guide.
  • Garmin: Garmin devices differ widely in features and menus. Check the battery-management options for your model rather than applying another Garmin watch’s instructions; Garmin also suggests reducing brightness in its battery-drain guidance.

Adjust cellular and other connections

If your watch has cellular, consider whether it needs to use mobile service while your phone is nearby. Google says Pixel Watch users can set mobile mode to Automatic, so the watch connects to cellular when Bluetooth or Wi-Fi is unavailable, or turn mobile off when it is unnecessary. With mobile off, some features are lost, including calls when the phone is offline.

Airplane Mode is appropriate only if you can go without the connections it disables. Google also cautions that Pixel Watch battery life varies with the watch series, usage, mobile network and signal strength, among other factors.

Cut back on streaming and demanding workouts

Streaming music from the watch can drain its battery faster than playing music downloaded to the device. If you want music during a long day, download it ahead of time where your watch and service support that option.

Check for a cause if the drain is sudden or persists

First review recent changes in use and settings: a newly enabled display feature, more background activity, weak cellular coverage, streaming or extended GPS use may explain a faster drain. If the pattern continues, check battery-health information and recent usage history if your watch provides them.

Rechargeable lithium-ion batteries gradually lose their ability to hold charge as they chemically age. Apple says Apple Watch can alert its owner when battery capacity is significantly reduced; follow the manufacturer’s service route if the battery-health information indicates a substantial decline. Apple’s explanation of battery aging and battery health is in its rapid-drain guidance.

Optimized Battery Charging is intended to reduce battery wear by limiting time spent fully charged, not to extend the current charge. Apple warns that turning off Optimized Charge Limit can increase wear and reduce battery lifespan, so it is not a routine fix for short runtime. Details are in Apple’s Optimised Battery Charging guidance.

Make changes in a useful order

  1. Identify the exact watch model and software version; open that manufacturer’s support instructions before following a menu path.
  2. Turn off Always On or shorten screen timeout, then reduce brightness if your model offers that control.
  3. Review background app activity and remove watch-face complications you do not need.
  4. Use the built-in power-saving mode on days when delayed notifications or reduced features are acceptable.
  5. If you have cellular, use Automatic or turn mobile off when appropriate; avoid streaming and reduce GPS or sensor activity when their full capabilities are not essential.
  6. If the battery still drains unusually quickly, check usage and battery health, then contact the manufacturer or its authorized service route if aging or a fault is indicated.
