How can I program the Android battery recharge time?

I wanted to know how we can find out how long it takes an Android device to fully charge the battery.

For example, if my battery is charged at 0%, then how long does it take to fully charge, i.e. 100%, the same thing, if my device is charging at 70%, so if I connect the charger now, then how long will it take to fully charge my device.

You should read the official documentation. Basically, you will need to use the BatteryManager class to find out the current state of the battery level.

This worked for me:

 private void batteryLevel() { BroadcastReceiver batteryLevelReceiver = new BroadcastReceiver() { public void onReceive(Context context, Intent intent) { context.unregisterReceiver(this); int rawlevel = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1); int scale = intent.getIntExtra(BatteryManager.EXTRA_SCALE, -1); int level = -1; if (rawlevel >= 0 && scale > 0) { level = (rawlevel * 100) / scale; } batterLevel.setText("Battery Level Remaining: " + level + "%"); } }; IntentFilter batteryLevelFilter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED); registerReceiver(batteryLevelReceiver, batteryLevelFilter); }
