If your Galaxy Watch battery is draining faster after an update, check the watch and app updates, background activity, health tracking, screen and notification settings, and network use before resetting anything. The timing alone does not prove the update caused the drain. Menu names and available controls vary by watch model and software version.
Why is my Galaxy Watch battery draining so fast after an update?
An update may coincide with faster battery drain, but it is not the only possible cause. Samsung lists apps, background activity, health features, connectivity, display settings, notifications, temperature, and battery or charger condition among the factors to check. Samsung does not publish a universal battery-life figure or a measured improvement for these settings, so judge the result on your own watch rather than expecting a specific number of hours.
How do I stop my Galaxy Watch battery from draining?
Work through these reversible checks first. Change one setting at a time, then observe whether the drain improves; that makes it easier to identify the cause without unnecessarily disabling features you use.
1. Install available watch and app updates
Samsung recommends keeping watch software and apps current, since an app may have a battery-consuming bug. For Galaxy Watch3 and newer, the phone-side path is Galaxy Wearable > Watch settings > Watch software update > Download and install. Wear OS watches may also check for software updates directly on the watch. App updates use the Play Store on Wear OS models; other models use the Galaxy Store update flow. Follow the instructions for your model because paths differ. See Samsung’s guide to updating watch software and apps.

2. Restart the watch if something seems stuck
If an app or update appears abnormal or stuck, restart the watch and check whether its behavior changes. Samsung includes restarting among its troubleshooting steps for update and app problems. A factory reset is intended for serious update failures, such as a boot loop—not as the first response to battery drain. If a reset becomes necessary, back up data you want to keep first because the reset can erase data.
3. Review background apps and health tracking
Close apps you are not using and review which apps are active in the background. Samsung also recommends checking automatic health features, including sleep tracking, automatic heart-rate measurement, and automatic stress measurement. Turn off only the tracking you do not need; doing so can reduce the data the watch collects. Samsung’s support pages explain battery troubleshooting and health-feature controls and reviewing recent or background apps and selected stored data. Back up anything you want to retain before deleting stored data.

4. Test display and notification settings
Always On Display keeps the screen visible, so switch it off as a test if you are comfortable raising your wrist or tapping the display to check the time. Also reduce unnecessary notifications, especially options that wake the screen or automatically show notification details. You can restore either setting if it does not help or the convenience matters more than the battery savings.
5. Check Wi-Fi and mobile connectivity
If the watch is repeatedly looking for Wi-Fi or using a weak network, turn Wi-Fi off when you do not need it and see whether drain changes. You can similarly turn off mobile networks when carrier service is not needed on an LTE/3G model. Turning off Bluetooth is a larger tradeoff: it disconnects the watch from the phone. These controls may be named or located differently on different models.

6. Use Power saving or Watch Only mode temporarily
Power saving can help preserve charge, but it reduces brightness and background functions and disables some connectivity or features. Watch Only mode is another option when you do not need smart functions. These modes are useful as temporary measures, not a way to preserve the watch’s full functionality.
7. Check temperature, watch condition, and charger
Samsung warns that extreme heat or cold can shorten battery life and may damage the watch. Inspect the watch and charger for physical or liquid damage, and use approved chargers and accessories. A replacement charger is relevant only if inspection points to a charging problem; make sure it is approved and compatible with your specific model.

Should I reset my Galaxy Watch after a software update?
Usually, no—not as an initial battery-saving step. Start with updates, a restart when appropriate, and reversible settings checks. A factory reset can erase data and is better reserved for serious software failures such as a boot loop. Back up data you want to keep before resetting, and follow Samsung’s model-specific instructions.

A passing result provides evidence about battery condition, but it does not prove that every software or app issue is resolved. If battery life remains abnormal after the checks above, or you suspect physical or liquid damage, contact Samsung support or arrange service.
