11 tips to extend your Samsung Galaxy battery life
Battery performance varies depending on usage patterns and device models, and optimal lifespan is generally outlined in the device’s user manual. Below are practical tips to maximize your Galaxy phone’s battery in daily use and maintain its long-term health.
1. Reduce display brightness level
A bright screen and extended screen-on time are leading causes of battery drain. Reducing brightness and screen timeout settings helps extend battery life.
- Swipe down from the top of your home screen to open the notification panel
- Drag the brightness slider to the left to reduce brightness
- Tap the gear icon > Select Display under My Device
- Tap Screen timeout and choose a shorter duration
Special Tip: Set brightness to Auto and screen timeout to 30 seconds for optimal power savings.
2. Close, disable or uninstall unused apps
Apps running in the background consume significant battery power even when not in active use.
- Long-press an app on the home screen > Tap Uninstall > Confirm with OK
- For deeper control: Go to Settings > Apps > Tap overflow icon to sort by size or permissions
- Select an app > Tap Uninstall
If the app can’t be removed (e.g., system apps), you can:
- Tap the app name > Select Disable to stop it from running and save battery
3. Turn off Always On Display (AOD) or set a schedule
While AOD is useful, it uses the AMOLED screen to display info and draws power even when the screen appears off.
- Go to Settings > Lock screen and security > Lock screen and Always On Display
- Turn off AOD by tapping the toggle
- To schedule AOD: Tap Set schedule and customize times
Special Tip: Schedule AOD to activate only at night if you wear a smartwatch during the day.
4. Toggle off Wi-Fi, Bluetooth and GPS when not in use
Leaving Wi-Fi, Bluetooth, or GPS on causes your phone to regularly search for connections, which quickly drains battery.
- Swipe down the notification panel and tap the icons to turn off each feature when unnecessary
5. Turn on Power saving mode
Power saving mode limits background activities, reduces CPU usage, lowers screen brightness, and disables features like vibration feedback to conserve energy.
- Navigate to Settings > Device maintenance > Battery
- Enable Power saving mode manually or set it to activate automatically
6. Download the latest device software
Keeping your phone updated ensures it runs optimized code, improving performance and battery efficiency.
- Go to Settings > About phone
- Use FOTA (Firmware Over The Air) or Samsung Kies to update your software
7. Check your device signal bars
Weak signal areas force your phone to boost transmission power, which leads to increased battery usage.
- Try to avoid using your device in places where signal strength is consistently low (few bars)
8. Check how often your device synchronizes data
Frequent syncing by apps like email or social media shortens battery life by repeatedly checking for updates.
- Adjust each app’s sync settings to update less frequently or only when opened
9. Avoid fully discharging your battery
Modern smartphone batteries don’t benefit from full discharges like older battery types did.
- Try not to let your battery drop below 20%, as frequent deep discharges may shorten its lifespan
10. Store your device properly
If you’re not using your phone for a while, store it with about 50% charge to maintain battery health.
- Avoid exposing the device to extreme heat or cold
- Don’t leave your phone in cars or attempt to store batteries in the freezer, which is a harmful myth
11. Know where to get help for battery-related issues
If issues persist, ensure you’re using original Samsung chargers and cables.
- If the device doesn’t power on, try a different charger/cable
- Persistent issues may indicate a faulty battery, in which case you should contact Samsung support
Tip: Consider investing in reliable mobile power accessories for on-the-go charging.
These tips can greatly enhance your Samsung Galaxy’s battery performance, helping you stay connected longer without frequent charging interruptions.
