Get the Most Out of Your Galaxy Phone's Battery

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.

Available screens and settings may vary by wireless service provider and software version.

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 touch Device care, and then touch Battery. To view your battery usage, touch Battery usage at the top of the page.

Battery Usage

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. Touch 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 touch the slider next to Accidental touch protection to turn it on or off.

Adaptive Brightness

If the screen is hurting your eyes, turn down the brightness to reduce eye strain and save battery juice. Talk about a twofer.

From Settings, search for and select Adaptive brightness. Then, touch Adaptive brightness again. To turn it on or off, touch the slider.

Power Mode

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 touch Device care. Touch Battery. Touch Power mode, touch your desired power mode, and then touch Apply.

Note: Power saving mode options can be customized before touching Apply.

Check out all your options to save power:

  • High performance: Maximum screen brightness and resolution. Uses more battery.

  • 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. You can also reduce battery usage by analyzing Wi-Fi usage.

From Settings, search for and select Wi-Fi. Touch Advanced and then touch slider next to Turn on Wi-Fi automatically.
