After experiencing a total battery life of 4 - 5 hours on the iPhone 5, iPhone 5s, and now the iPhone 6, I have come to the conclusion that this problem has to be related to my iCloud account and/or some combination of settings I currently have enabled. Please help me troubleshoot this issue, as I can't live like this. When I first powered on my shiny new iPhone 6, the battery was around the 73% mark. I usually don't do iCloud backups, as I know they can cause issues, but I decided to take a chance this time. My last iCloud backup was made last night from my iPhone 5s. It included contacts, messages, settings, bookmarks, and some applications. I initiated an iCloud restore around shortly after receiving my iPhone 6, and was disappointed to see the battery begin dropping 1% every two minutes or so. I started using my phone around 11:30 AM and it died at 3:30 PM. I realize I didn't start using my phone until the battery was already around 70%, and that I was more-or-less using the phone non-stop for this period of time, but this kind of battery life still seems abysmal, especially for simple tasks like web browsing, streaming music with the screen turned off, taking a few pictures, etc. Interestingly, I noticed that my home screen still said "iCloud restore in progress" hours after I had first selected the option of restoring. As a result, I went into my settings and ended the restore. Everything had already seemed to have restored anyway. I then began disabling the obvious battery-draining culprits: - Limiting Ad-Based Locations - Disabling Background App Refresh - Disabling Location Services - Disabling Parallax Wallpapers - Disabling Automatic Updates - Closing Multiple Safari Tabs - Reducing Screen Brightness - Resetting Network Settings - Resetting All Settings (and then disabling those settings listed above) None of this seemed to make any difference though, as battery continued to drain at the same rate. I have since allowed the battery to fully drain and am recharging it now. Note: I am in an area that gets three bars of LTE service. The only other thing I can think to do is to erase all settings and maybe not sign in with my iCloud account? Here are some screenshots I captured of diagnostic related information, which may prove to be useful. If anyone has any insight they could offer, I would seriously be very grateful.
