Since I upgraded my iPhone 6 Plus to version 8.4, my battery has dropped 30% in one hour. I've seen many posts on these threads regarding people complaining about their battery dropping, and I guess I always thought it was ridiculous or not true. However for the first time, I'm seeing it for myself. Does anybody else have this issue? My photo gallery is all messed up as well and I will have to fix it when I get home.
