To make a Samsung Galaxy Watch last longer between charges, start by turning off Always On Display, reducing screen wake-ups and brightness, and limiting features you do not use. If the watch still drains unusually quickly, check for recent setup activity, temperature or charging problems, then run Samsung’s battery diagnostic. Settings and menu paths vary by model and software version, and Samsung does not give a universal number of extra hours any one change will save.
Start with the display
The display is a practical first place to cut power use: an always-visible face and frequent screen activations keep the screen active more often. Change one or two settings at a time so you can see whether the trade-off suits you.
Turn off Always On Display
On the watch, open Settings > Display and switch off Always On Display. On some models, the option is under Watch faces > Watch always on; it may also be available in the Galaxy Wearable app. The clock will no longer remain visible when you are not actively using the watch.

Reduce brightness and screen activity
Lower brightness to a comfortable level and shorten the screen timeout. If the display wakes accidentally, turn off wake gestures or touch-to-wake where those options are available. You can also cover the display with your palm to turn it off. Names and locations of these controls differ by watch model.

Cut unnecessary notifications and connections
Limit notification wake-ups
In Galaxy Wearable, open Notifications and disable alerts from apps that do not need to reach your wrist. On supported models, review whether notification details appear automatically and whether notifications turn on the screen. Fewer alerts mean fewer screen activations, but you will see fewer notifications on the watch.
Switch off radios and assistant wake-up features you do not use
Turn off Wi-Fi when you are not using a Wi-Fi connection. If your watch supports LTE, switching off mobile networks disconnects it from the carrier network; switching off Bluetooth disconnects it from your phone. Only disable either connection if you can do without the features that rely on it. Samsung also identifies GPS and Bixby or Google Assistant voice wake-up as features to consider disabling when unused.

Adjust health monitoring to match your needs
On applicable models, Samsung lists options to measure heart rate and stress every 10 minutes or manually rather than continuously. Less frequent monitoring means less frequent readings, so choose a setting that still meets your needs.
Watch7 and Watch Ultra: Limit health features
Samsung documents Limit health features for Galaxy Watch7 and Galaxy Watch Ultra. It disables workout auto-detection, certain high- and low-heart-rate alerts, background heart-rate monitoring, and movement and respiration tracking during sleep. Samsung says sleep score is not calculated while the option is enabled. Check the feature description on your watch before turning it on if you rely on those measurements or alerts. Samsung’s Watch7 and Watch Ultra guidance describes these model-specific effects.

Use Power Saving mode when its limits are acceptable
Power Saving mode applies several restrictions at once. Depending on the model, it can turn off Always On Display and Wi-Fi, disable wake gestures, reduce brightness or screen timeout, limit CPU performance, and restrict background network, location and sync activity. Review the confirmation screen or mode settings on your watch: the exact effects vary.
On many models, find it under Settings > Battery or Settings > Battery and device care; some watches also offer a Quick Panel control. Use it when you need to conserve power and can accept fewer connected or background functions. Samsung does not provide a model-independent runtime gain for the mode.

Check whether the drain is temporary or unusual
Give a newly set-up watch time to settle
Samsung says setup, app installations and learning your usage patterns can increase battery drain, and performance may optimize over about the first week. This is general guidance, not a guaranteed deadline. If drain remains unusually fast, review the settings above and check which apps or features are active.
Check temperature and charging equipment
Very hot or cold conditions can shorten battery life or damage the watch. Inspect the watch and charger for physical or liquid damage, and use a Samsung-approved charger and accessories designed for your exact watch model. A different charger is not a runtime upgrade; this advice is about proper, reliable charging.
Run Samsung’s battery diagnostic
If unusual drain persists, use the Samsung Members app on a paired Samsung phone to run a watch battery diagnostic. Samsung’s battery-drain troubleshooting page covers the diagnostic and other checks.
Choose changes by the function you can give up
Samsung’s support guidance describes these settings qualitatively, not as guaranteed hours or percentages saved. The practical choice is whether the power reduction is worth the feature you lose.

|---|---|---|---|
| Turn off Always On Display; reduce brightness or wake-ups | Samsung identifies these as power-saving display options; no universal runtime figure is stated. | The face is not always visible, or the screen is dimmer and wakes less often. | Everyday use when you do not need a continuously visible face. |
