BatteryStatsLibrary
BatteryStatsLibrary is an Android library for implementing basic battery informations and to calculate remaining time for charge and discharge.
This library provides a background service to track the battery usage and reports almost accurate time to charge and discharge.
Installation
dependencies {
compile 'com.github.lvabarajithan:batterystatslibrary:1.0.0'
}

How to use
To track the changes in battery, create an instance of BatteryStats class.
BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
BatteryStats batteryStats = new BatteryStats(intent);
}
}
;
registerReceiver(broadcastReceiver, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
To get current level of battery..
int level = batteryStats.getLevel();
To get the live time like in the Screenshot
int liveTime = batteryStats.getLiveTime();
Check against the default values, (view sample)
BatteryStats.LIVE_TIME_MORNING BatteryStats.LIVE_TIME_AFTERNOON BatteryStats.LIVE_TIME_EVENING BatteryStats.LIVE_TIME_NIGHTAnd one more... To listen for battery changes once, create an instance of BatteryStats class with context.
BatteryStats batteryStats = new BatteryStats(context);
boolean charging = batteryStats.isCharging();
Coolest part
To calculate the remaining time for battery to charge and discharge, Create a class extending BatteryTimeService.
public class NotificationService extends BatteryTimeService {
@Override
protected void onCalculatingChargingTime() {
//Called while charging and time to charge is being calculated.
}
@Override
protected void onChargingTimePublish(int hours, int mins) {
//hours and mins params indicates remaining time for full charge.
}
@Override
protected void onDischargeTimePublish(int days, int hours, int mins) {
//days, hours and mins params indicates remaining time for discharge.
}
@Override
protected void onCalculatingDischargingTime() {
//Called while discharging and time to discharge is being calculated.
}
@Override
protected void onFullBattery() {
//Called when device is charging and battery becomes full.
}
/**
* Other default Android service methods can be overridden.
*/
}
Finally declare the service in AndroidManifest.xml
<service android:name=".NotificationService"
android:exported="false"/>###Note
The calculated time may be inaccurate at first. Later, after tracking the battery usage for 3-4 levels, It reports almost accurate time.
