My nexus 4 was doing a great job conserving battery life till yesterday. I have turned off 4g/3g and selected "Use only 2g networks". If i could cut 2g, I would. I turn on wi-fi, maybe two or three times a day for 10-15 minutes and my screen usage is very minimal. The battery report below shows that I was getting good life from the battery.
Yesterday, i noticed the battery depleting pretty rapidly and by today the phone was dead (Nearly missed a meeting without the phone alarm). Once I started charging, I got this usage report.
Between the two reports, no new updates had been downloaded/installed. I did not open or start the map application in any way between the two reports. Since this incident, I have disabled the "Access to my location" option under Settings-Personal-Location Access, but I do not believe its an appropriate solution. After disabling 4g/3g usage followed by frugal wi-fi activation, the solution should not be to cut out a core feature of the android experience. I suspect this to be a software issue and wonder if I am alone in facing this problem.
