Turn Off Always‑On Display
Disabling the always‑on display prevents the screen from staying partially lit when locked, saving power especially on AMOLED panels.
Reduce Screen Refresh Rate
Set the refresh rate to 60 Hz instead of higher rates like 90 Hz or 120 Hz to lower GPU workload.
Enable System‑Wide Dark Mode
On AMOLED devices, dark mode turns off pixels for black areas, cutting energy consumption.
Use Adaptive Brightness
Let the ambient light sensor automatically adjust brightness instead of keeping it at maximum.
Limit Background App Permissions
Restrict apps that don’t need constant network or location access.
- Open Settings → Apps → Select an app → Permissions
- Turn off “Background activity” for rarely used apps
Switch from 5G to 4G When Speed Isn’t Critical
5G drains more power; switching to 4G can extend battery life.
- Settings → Network & internet → Mobile network → Preferred network type
- Select “4G/ LTE”
Avoid Third‑Party Battery Saver Apps
Android already optimizes power; extra saver apps may run continuously and waste energy.
Disable Unnecessary Sync and Connectivity
Turn off sync for accounts you don’t need and toggle off mobile data, Bluetooth, or location when not in use.
- Quick‑settings panel: swipe down and tap the icons
- Settings → Accounts → Sync settings
