以下方法用于在 Android 中节省电池寿命:

 •Disable 3G connectivity and tell the device to only use 2G networks.
 •Put your phone on standby mode when you are not using it.
 •Set your screen timeout to the shortest length possible.
 •Use the Power Control widget.
 •Reduce the brightness of your display.
 •Put the device in “Airplane Mode” while on an airline flight.
 •When traveling, take your charger as well as a USB cable with you and get a car charger.
 •Set a reasonable update frequency for apps.
 •Turn off the phone vibration function.
 •Turn off the GPS.
 •Turn off the Bluetooth feature when not needed.
 •Turn off the wireless feature when not needed or set a Wi-Fi timeout.
 •Switch off auto-sync.
 •Do not leave applications running when you don’t need them.

BatteryManager除了通过总电池电量和粘性广播之外,没有任何 API 可用于获取您寻求的信息。

为了获得最优化的使用和备用电池,请执行以下操作:-

  • 最小亮度,不使用自动亮度。
  • 不需要时打开 WIFI、蓝牙、数据包、GPS 和自动旋转。
  • 将壁纸设置为深色(全黑色壁纸是最好的)
  • 在设置->开发者选项->关闭Window动画比例、Transition动画比例和Animator持续时间比例。
  • 关闭振动器模式
  • Moreover when low battery, change to silent mode instead of vibrate mode.
