You will see battery levels of both headphone and the charging base every time you connect or disconect to the Mi Air 2, and even with screen OFF!!!(XIAOMI DO NOT DO THAT!!)
Even more , double click on left headphone will PLAY NEXT SONG!!

Acces Location is needed to detect Mi Air 2(Google mandatory sorry).

No battery used as it only works when you connect/disconnect your Mi Air 2.

On same devices you have to first take off one headphone, wait till your mobile vibrates(about 5 seconds later) and then wait 3 seconds and take off the other headphone to see the battery status of your Mi Air 2

THERE IS NO DEMO VERSION, IF IT DOES NOT WORK FOR YOU, GOOGLE WILL REFUND YOUR MONEY IN 1 HOUR
Hope you enjoy!!


WATCH!! FOR XIAOMI DEVICES YOU HAVE TO MANUALLY GRANT THESE 2 PERMISSIONS(SHOW ON LOCKSCREEN AND POP UP WINDOWS ON BACKGROUND), IT IS SOMETHING XIAOMI EXCLUSIVE AND CAN NOT BE DONE PROGRAMATICALLY..SORRY

ALREADY WORKS ON ANDROID 9 AND 10.

MAKE SURE YOUR DEVICE LOCALIZATION IS ON!!!!

FINALLY UPDATED TON ANDROID 11!!!IN THIS VERSION YOU HAVE TO GIVE ACCESS ALL TIME TO LOCATION(THANKS GOOGLE)

UPDATE..ON XIAOMI ,HUAWEI AND OTHERS YOU HAVE TO DISABLE BATTERY OPTIMIZATION ON THIS APP!!!OTHERWISE ANDROID WILL KILL IT AND STOP WORKING
