Get the most out of your Galaxy phone's battery

Can't figure out why your battery is always draining? Your phone has the answer. You can monitor and extend its battery life or use a Power saving mode to get the most out of it. You'll never be stumped about your phone's battery life again.

Note: Available screens and settings may vary by wireless service provider, software version, and phone model. 

Battery usage

You can view the estimated battery life based on how much you've used over the past week. You can also closely monitor how much battery your apps are eating up. Now you'll have no surprises.

From Settings, swipe to and tap Device care, and then tap Battery. To view your battery usage, tap Battery usage at the top of the page.

Screen timeout

Sometimes your phone just needs to take a timeout. If needed, you can shorten your phone's screen timeout to save battery life.

From Settings, search for and select Screen timeout. Tap Screen timeout again, and then select your desired option. Choose 15 seconds to save the most battery life.

Note: Screen timeout is set to 30 seconds by default.

Accidental touch protection

You can reduce battery strain and stop embrassing pocket dials by blocking accidental touches. That way, you won't have any more mishaps.

From Settings, search for and select Accidental touch protection. Then, tap the switch next to Accidental touch protection to turn it on or off.

Adaptive brightness

If the screen's hurting your eyes, turn on Adaptive brightness. It will learn your usage patterns and automatically adjust the screen's brightness based on your prior adjustments.

From Settings, tap Display, and then tap Adaptive brightness. To turn it on or off, tap the switch.

If you want Adaptive brightness to start over from the beginning, tap Reset usage patterns, and then tap Reset. It will begin learning your usage patterns all over again.

Power mode

Note: The use of power modes can affect app and device performance. Some tasks and features may take longer to complete or update. Additionally, apps running in the background may not receive updates or send you notifications when power saving modes are enabled.

Before you turn in for the night, change your phone's power mode. This will decrease your phone’s performance and save battery life.

From Settings, swipe to and tap Device care. Tap Battery, and tap Power mode. Tap your desired power mode, and then apply your desired settings or customizations. Finally, tap Apply.

Check out all your options to save power:

Power mode with Optimized chosen
  • High performance: Maximum screen brightness and resolution. Uses more battery. This option is not available on all devices.

  • Optimized: Get the recommended balance of performance and battery life.

  • Medium power saving: Extend battery life by limiting some functions.

  • Maximum power saving: Save as much battery as possible. 

Adaptive Wi-Fi

If you're always on Wi-Fi browsing your favorite blogs and video channels, you can save power on that too. Plus, you can reduce battery usage by analyzing Wi-Fi usage.

From Settings, tap Connections, and then tap Wi-Fi. Tap Advanced, and then tap switch next to Turn on Wi-Fi automatically.

Note: This feature is not available on all phone models.
