I can't say that it will fix the OP's issue, but i can't say that it won't either. Apparently he has some kind of unique problem, since you have the same phone and the same software version and yours is okay. Unfortunately, i do not use that email or else i could see if it works on my phone too.Originally Posted by Miklb58
From my own experience with installing the upgrade (along with battery training, and FDR), it greatly improved my battery life and a few other issues. I suppose that waiting for the official release is an option, but considering how long you need to wait for "official" releases...you could be waiting awhile.
