What to do when your Samsung Galaxy device battery drains faster
Your Galaxy device may consume battery faster due to environmental conditions, background apps, or the condition of the battery. Follow the cases and solutions below to maintain stable performance and extend battery life.
Note: The battery is a consumable component. With repeated charging and discharging, its capacity will gradually decrease, and the reduced capacity cannot be restored.
Reasons why your Galaxy device’s battery drains quickly
Initial setup period
When you first start using your Galaxy phone, battery consumption may temporarily increase. This is because various apps and services are being optimised during the first few days. Once optimisation is complete, the battery usage will normalise.
Weak network signal
When your network connection is unstable, call quality and signal strength may decrease, which can result in faster battery drain.
Note:
- You can move to an area with a stronger signal to reduce battery consumption.
- Regularly restarting your phone can help reduce battery consumption.
- Restarting your phone occasionally also helps maintain optimal performance.
How to reduce battery drain
1. Reduce battery drain by switching off unused functions and apps
Applications that use auto sync, Wi-Fi, Bluetooth, or GPS can increase battery consumption. Switch them off when they’re not in use.
Step 1. Swipe down from the top right of the screen to open the Quick panel.
Step 2. Switch off features that are not in use, such as Wi-Fi or Bluetooth.
Note: Apps in power saving mode will have limited notifications or background activity.
2. Use Device optimisation to improve battery performance
Device optimisation removes unnecessary files and background apps, helping to reduce battery consumption and improve overall performance.
Step 1. Tap Settings.
Step 2. Select Device care.
Step 3. Tap Optimise now to optimise your device.
3. Set apps to the sleeping or the deep sleeping mode to reduce battery consumption
Set unused or infrequently used apps to the Sleeping or the Deep sleeping mode to reduce battery consumption on your Galaxy device.
Step 1. Tap Settings.
Step 2. Select Battery.
Step 3. Select Background usage limits.
Step 4. Select Sleeping apps or Deep sleeping apps.
Step 5. Tap the Plus icon.
Step 6. Select infrequently used apps and tap Add.
Note:
- Sleeping mode apps may not refresh or send notifications immediately.
- Deep sleeping apps do not run in the background at all and only work when opened manually.
4. Turn on Power saving mode to reduce battery consumption
When Power saving mode is turned on, your phone restricts background data use for unused apps and disables high power features such as Always On Display to extend battery life. You can also customise options like limiting CPU speed, lowering screen brightness, or turning on Dark mode as needed. Infrequently used apps can be set to Power saving mode, so they don’t run automatically in the background.
Step 1. Tap Settings.
Step 2. Select Battery.
Step 3. Select Power saving.
Step 4. Turn on the Power saving mode, and then select additional restrictions as needed.
Note: Messages or notifications from sleeping apps may be limited.
5. Uninstall downloaded apps that drain your Galaxy device’s battery
Some downloaded apps may consume your Galaxy device’s battery excessively. Identify and uninstall such apps to reduce battery drain.
Step 1. Tap Settings.
Step 2. Select Battery.
Step 3. Tap on the battery graph.
Step 4. Select the apps.
Step 5. Check the detailed Battery usage for app.
Step 6. Select the app you want to remove.
Step 7. Tap Uninstall.
Step 8. Tap OK to confirm removal.
