To extend battery life, reduce screen brightness, enable power saving mode, and close unused apps running in the background. Additionally, consider disabling location services and background data for non-essential apps.
If your device is not charging, ensure the charger and cable are working by testing with another device. Check the charging port for debris and clean it gently. If the problem persists, try using a different charger or cable.
