I RMA'D it to Sony and I'm awaiting response, I couldn't be phoneless so I bought a second z2
z2...I'm pretty sure everything is setup the same, and I've followed the battery saving guide posted here.
However I'm getting much worse battery life. My old z2 was getting am easy 16 hour day with 4-5 screen time, now I'm lucky to get 10-12 hours with 3-4 screen time.
Anything I can do to try and figure this out?
