Hi everyone, My Nexus 4 has started switching itself off within the last few days. When I boot back up, the phone has over 80% battery charge, although once it was at 0% which was weird. It also feels like I have to charge it more often. The only thing that's happened recently is I enabled a big update of all my apps. Previously, my apps were not automatically updated - the other day, I decided to just let the updates go ahead as I was sick of the warning notification. Now this switching off nonsense has started. Any ideas what I should begin to look for to fix it? I've checked which apps are running in the background, and it doesn't look too much different from prior to the mass app update - I don't have loads of apps in the background (CoolSymbols; Light Flow; OneDrive; ES File explorer; Whats App; Google Services; TouchPal). Any ideas would be muchly appreciated. Thanks.
