Samsung Galaxy Phone Battery Draining Fast
Your Samsung Galaxy battery is draining quickly? This guide will identify and resolve common causes of rapid battery drain.
Step 1 | Power Hungry Apps
View battery-draining apps in Settings > Battery and device care > Battery > Using since last full charge.
- Uninstall unused apps from Settings > Apps.
- Alternatively, enable "Put unused apps to sleep" in Settings > Battery and device care > Battery > Background usage limits.
Step 2 | Display Settings
Optimizing display settings can significantly reduce power consumption.
- Disable the Always On Display in the Settings app > Lock screen, or schedule it for a specific time.
- If necessary, turn off Power saving mode to disable Always On Display.
- Lower the display resolution to HD+ or FHD+ in the Settings app > Display > Screen resolution.
- Reduce the screen refresh rate from High to Standard in the Settings app > Display > Motion smoothness.
Step 3 | Battery Degradation
Batteries have a limited lifespan and may be damaged by improper use.
- Check your phone's battery health using the Samsung Members app, available from Google Play store.
- Run the battery test under the support tab, selecting phone diagnostics.
Look for signs of battery expansion, such as:
- Separation of the enclosure
- Localized screen discoloration
- Bowing of the housing
If diagnostic tests fail or you see these signs, replace the battery.
