Get the most out of your Galaxy phone's battery

Cannot 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 will never be stumped about your phone's battery life again.

Note: Information provided applies to devices sold in Canada. Available screens and settings may vary for smartphones sold in other countries.

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

Battery usage

Open Settings, then swipe to and tap Battery and device care, and then tap Battery. Your battery usage will appear at the top of the screen.

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

Screen timeout

Navigate to and open Settings, and then tap Display. Tap Screen timeout, and then select your desired option. Choose 15 seconds to save the most battery life.

Note: The screen timeout is set to 30 seconds by default.

You can reduce battery strain and stop embarrassing pocket dials by blocking accidental touches. That way, you will not have any more mishaps.

Accidental touch protection

Navigate to and open Settings, and then tap Display. Swipe to the bottom of the screen, and then tap the switch next to "Accidental touch protection" to turn it on or off.

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

Adaptive brightness

Navigate to and open Settings, and then tap Display. Tap the switch next to "Adaptive brightness" to turn it on or off.

Note: Using Power saving mode 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 mode is 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.

Navigate to and open Settings, and then tap Battery and device care. Tap Battery, and then tap Power saving mode.

Power saving mode

Tap the switches next to your desired settings or customizations. Finally, tap the switch at the top of the screen to activate Power saving mode.

If you are 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.

Open Settings, then tap Connections, and then tap Wi-Fi. Tap the More options icon (the three vertical dots), and then tap Advanced.

Adaptive Wi-Fi

Tap the switch next to "Turn on Wi-Fi automatically".

Note: This feature is not available on all phone models. Additionally, it may only work when a SIM card is inserted.

Opening apps all day can drain your phone's battery quickly, but you can save some power with sleeping apps settings.

Sleeping apps

If there are certain apps you rarely use, you can set them to sleep in the background so your battery will not drain as fast. You can also set apps to sleep automatically when you have not opened them in a while.
