I installed the Jelly Bean update last night and since then my battery seems to be draining a lot laster. I took the phone off charge at 6am this morning and im down to 50% already without actually using the device very much (I have changed some of the desktop around and looked at the settings)
My Battery usage is showing
android system 16%
android OS 9%
Its all very minor things from then on down, nothing stands out.
I have set the screen brightness to auto adjust but has anyone else had any problems? Im wondering if I am just missing a setting for my data syncs or something obvious but nothing is jumping out on me.
im running version 4.1.1 on VodafoneUK
when you tap on screen % it should tell you the length of time thats more important than the % if you had the screen on for 2hours than yes that battery drain is normal
