MakeUseOf has listed Android settings that may reduce battery use, including Always On Display, background apps and Wi-Fi and Bluetooth scanning. The effect depends on the device and how it is used.
MakeUseOf recommends starting with the screen: turn off Always On Display if persistent clocks and notifications are not needed. The publication also advises checking which apps are allowed to run in the background and limiting rarely used apps that may consume power.
Another suggestion is to review Wi-Fi network and Bluetooth-device scanning. The article notes that Android may continue scanning even after the main Wi-Fi or Bluetooth switches are turned off. The scanning controls are in Location settings and location services.
MakeUseOf also recommends reviewing location permissions, since social-media and shopping apps may not need constant access to a user’s precise location. Adaptive charging and a charge limit are additional options where a phone supports them.
Androidworld writers have separately warned that regularly draining a phone below 20% may accelerate battery wear. These steps will not have the same effect on every model, so users should check which controls their own device offers.
