How to optimise the battery life on a Galaxy smartphone
Galaxy phones are designed to offer high performance and excellent battery life. However, battery life depends on how the battery is used and different devices have different battery life. To find out how to optimise the battery on your phone try following some of our tips.
General tips:
- When charging your phone for the first time, wait for the battery to be fully charged.
- Aim to keep your smartphone between 20-80% charged (you don't need to wait for the battery to run out of charge completely before charging your phone).
- Install the latest software version and keep apps updated. These updates may contain important battery-related improvements and can fix known malfunctions.
Please note: The steps and images shown in this FAQ may vary between devices. If the steps do not match your device try and follow the closest match on your device.
The easiest way to save power is to turn on Power saving from the swipe down menu.
You can also check the battery consumption data directly from the Galaxy device menu:
Long screen time-out settings or high display brightness can substantially reduce the battery. To save battery, consider lowering your brightness setting, deactivating auto-brightness, reducing the sleep timeout setting and adjusting your screen resolution and wallpaper.
- Use display standby: Put the display on standby every time you don’t need it by pressing the Power button.
- Reduce "Screen timeout" delay: You can decide how long the screen remains active after the last touch. The screen timeout is set to 30 seconds by default. You can choose between several settings in a range from 15 seconds to 10 minutes. Go to Settings > Display > Screen timeout.
- Change the Always On Display settings: Go to Settings > Lock screen > Always On Display > tap the switch to on.
- Reduce screen brightness: Swipe down from the top of the screen to reveal the quick panel, then use the slider to adjust the brightness. Alternatively, go to Settings > Display.
- Deactivate auto-brightness: Go to Settings > Display > Deactivate Adaptive brightness.
- Activate Dark Mode: If device has AMOLED display, switch to Dark Mode. If you are using a previous Android version, the function may be called “Night mode”. Go to Settings > Display.
- Reduce sleep timeout setting: Go to Settings > Display > Advanced > Sleep.
- Reduce the screen resolution: Go to Settings > Display > Change screen resolution.
- Activate "Accidental touch protection": Prevent your phone from taking unintentional action while holding it in your pocket. Go to Settings > Display.
- Check your wallpaper: Live wallpapers can reduce battery life. Regular wallpapers are more battery-friendly. If device has an AMOLED display, dark wallpapers help with battery life. Go to Settings > Wallpaper.
To save battery, choose the features that you would like to activate or deactivate according to your usage. For example:
- Deactivate Bluetooth when it's not in use.
- Deactivate Wi-Fi when you're not using it or when you are using mobile data instead.
- Deactivate GPS or improve its accuracy.
- Activate Flight Mode when you're not using the phone connectivity.
- Disable applications running in the background, which may continue to operate or update which will consume battery.

Battery optimisation
Battery optimisation takes place automatically every day and allows you to keep the performance of the device at its best. It carries out several actions:
- Storage cleaning.
- Delete unused files and close applications running in the background.
- Manage the battery usage when it is not compliant.
- Search for blocked applications and malware.
To optimise the battery manually, go to Settings > Device care > Optimise now.
You can also set your device to automatically optimise your device. From the Device care menu:
Power Modes
The power savings options available depend on your device and the version of Android it is running. In the latest models, you can choose between the following:
- High performance: high system speed
- Optimised: 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
Background usage limits
You can use this setting to limit how much battery power selected apps use. From the Device care menu:
The Samsung S22 brings new power-saving features designed to maximise the battery life of your phone.
From the settings page:
- Adaptive battery: Limits the battery usage for apps that you do not often use.
- Processing speed: This can be adjusted between Optimised, High and Maximum. Using Optimised takes less strain on the battery and saves power.
- Protect battery: This limits the maximum charge on your phone to 85%, increasing the lifespan of your battery, meaning your charge will last longer.
