After completing the second part of the Motorola Droid Turbo 2 system update this week, my battery completely drained. Now it won't charge hold a charge and it takes 8 hours to charge 100%. Any solutions? My entire family has the exact same phone and no one else had this problem with the update. I also tried using their phone chargers to make sure it wasn't a charger issue but that didn't help either; even though they have the exact same charger for the same phone. I tried shutting off my phone to let it charge overnight, and it eventually got to 100%. But the charge drains quickly, even when not in use. Any suggestions?
