Get the remaining battery time available from an Android phone

Is it possible to get the remaining battery time available from an Android phone?

Thanks.

Solution

  • You can get battery life with help of broadcast receiver by registering a receiver for action Intent.ACTION_BATTERY_CHANGED. My answer is key only, get information from Android Developers website.

    By using the below statement in onReceive() method of BroadcastReceiver with above Intent action, you will get battery level currently available(e.g., 50%, 60%, etc.). But you can't estimate the time remaining, because some apps may consume more power. So i think battery level to time remaining conversion won't give correct result.

    battery_level = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);

    I hope it may help you.
