I have actually been having the same issues. Maybe not right after that update, butall of a sudden my battery is just dying twice as fast when im not even using it often. I now keep a charger with me at work. Very strange.
After the last update to my Droid DNA, they took away Silent mode. Does anyone have ANY IDEA what so ever when they plan to fix that? I cant have my phone just on vibrate...
Thanks so much in advance all!
