    Unfortunately I do use the calendar, and Google search quite a bit... but I might try it just to test out.

    Had full charge before I went to bed and left it unplugged with all apps closed. Even did a restart before going to bed. Huge drop in battery life for this many hours completely idle. I had received a text, email, and words with friends notification. Android os use is killing this thing. Also running a live wallpaper, phase beam, but since the screen is off it shouldn't matter right?

    I flashed the 4.0.2 factory image last night to start from scratch... getting much better results today. Still not great, but a definite improvement... Android OS still using too much, but it's a step... this is mostly on wifi, with a couple hours on 4G - and a LOT of usage since I got up this morning.

    Dezy mine was like that yesterday too - uber-high... :(

    Also someone in that XDA thread posted using a different battery seemed to make a big difference in Android OS' "keep awake" usage... weird.

    I haven't restarted and used the phone quite a bit this morning for a good 45minutes. My android OS use went down to 25%....wondering why it would be higher when it's idle. I also use Airdroid whenever I'm home and yet the OS % went down...very strange. I hope 4.0.3 fixes this issue, it's not a huge concern, but certainly puzzling

    After 6 hours on my screen's at 57% and Android OS is only 16% with the battery at 38%, was full on browsing/video watching/4G LTE entire time ect...

    Somethings up on your end for sure with that high Android OS %.

    Don't know, like I said at idle it was at 45%, which I did not touch for a good close to 8hrs as I was sleeping. After use this morning and now (just checked), I'm at 25%. Something strange is going on....

    My battery after second charge. You can see its been used.

    Your os is killing your battery. Factory reset it. My tb used to do that when rooted. Hated that.

    Btw when they introducing this phone they were talking about some setting that shows what app may be miss behaving I don't know where to find it though. Been looking myself.

    So you had this exact problem with your TB? It's weird though cause when rooting/unlocking the Nexus it asks for a factory reset. Man I just got this phone set up the way I like too...:frown:

    Oh ye. Happened a lot after I rooted it had a rom for like two months before my phone started having a mind of its own.

    One day it was fine the next....same thing. Especially when I held the power button and did a restart.


    I'm not rooting this for now don't want problems to start.

    All I did was root it, no ROM.

    I'll do Titanium backup and just factory reset tomorrow if this problem still comes up. Thanks!

    Seems like the more I use the phone that Android os does go down, now at 19%. After using titanium backup and then now using the DF app

    Correct me if I'm wrong, but Android OS should rarely be over 10% right?
