Has anyone seen this before?

I think my battery problems are directly linked to my signal strength, which oddly enough, seems to be linked to my screen being on! O.o

I live in downtown Montreal and am on rogers/fido so I should have excellent signal strength. But for the week or so that I've had my phone, I have noticed that I am getting terrible signal. And the data even dies out for a second or so sometimes.

Looking at the battery stats, for some reason, the signal is horrible exactly when the screen is on, but great while the screen is off.

I am running stock 4.2.2 rooted with trinity. But have had this problem even when I was full stock :s
[Nexus 4 General] nextelbuddy:
if your signal strength is weak then your radio is working harder trying to acquire signal thus killing your battery.
[Nexus 4 General] asb123:
Yup, of course. But i am talking about how the signal is perfect (as it should be in downtown) when the screen is off. But when the screen is on, signal strength goes awful.

[Nexus 4 General] psubadger:
I got my nexus 4 right after 4.2.2 started rolling out, and I don't have the largest sample size, but my battery life has been well beyond my expectations. With a day of use that gives me about 1:30 to 2 hours of screen on time, I have about half of my battery left before I go to bed. That's plenty good for me. Clearly that's without any comparison to other versions of 4.2, but still.

When I try to do what you have done above in IncrediControl and then click 'Apply' the phone always reboots? I have not checked 'Set on Boot' so I assume the changes are not applied? From a guide I read it said it's safer not to check 'Set on Boot' as this could be dangerous? Does your phone automatically reboot after making changes?

Thanks,

Can someone test how many hours battery lasts during heavy 3d gaming (shadowgun, nova 3, need for speed, dead trigger etc).
[Nexus 4 General] Ricolando:
Yeah this phone has been bizarre thus far. Yesterday I was able to get 4.5 hrs of screen time (auto brightness set) with 11 hours of total usage before I plugged in with 14%, but today "Maps" ate a ridiculous amount of battery (even though I never opened it and Google Now isn't enabled) and I was down to 58% in about 5.5 hrs with screen time at less than an hour. The only other app I used was Play Music in offline mode. Sorry no screens at the moment. I force quit the Maps process and rebooted the phone. We'll see what happens now. I'm not too worried because my Gnex fluctuated drastically between different ROMs and Kernels, and like I said before, yesterday my battery life was pretty amazing.
[Nexus 4 General] resynx:
Did you make sure to go into the Maps settings and disable the auto update location ?
[Nexus 4 General] BarryH_GEG:
It's a world One X owners have lived in for a while now. Get one of these. It's slim, rounded, and fits easily in a pocket. I use this when I'm home and don't want to take any chances like if I know I'll have a lot of talk time.

For when I'm traveling and on planes and need my device(s) fully charged when I land I bring this. It can charge two devices at once (even tablets) and is high output and can get the phone from 20% to 70% in about a half hour.

[Nexus 4 General] sarkster:
Finally killed my battery when I got in tonight from work. As I mentioned before, I am a competitively light user I expect. My phone usage consists of SMS, picture taking (with auto upload to g+), Google music in the car, some light web browsing, use of a few other apps, quite a bit of gmail, 10-15 minutes of phone calls,gps and Google now on at all times and Facebook notifications.

My settings are as follows. Screen on auto at all times. At home or work I have WiFi on and mobile data off with force 2g, sync on and gps on. When in car I turn WiFi off and mobile data on and un check 2g. When going to sleep I turn off sync, gps and WiFi.

Charging from flat to 100% took about 2hrs. I'm fairly happy with the stats so far though as I say, I'm a light user.
[Nexus 4 General] silverbladef:
this is what I've been getting today. I was mostly using the device for text messaging, emails, streaming Google Music with Google now and GPS are off for half of that period.I would say that this is not satisfactory and it will take some time to get use to. Looks like I'll have to carry a charger with me from now on.

[Nexus 4 General] aceo07:
100% to 17%. 9hrs later. 3:11hrs display on, 1:37hr gps, 50%+ poor/gray reception, 35% brightness.

It's not great, but acceptable. The next few hours I probably won't use the phone much and I'll see how much idling it can do before I need a recharge.

edit: 11:28hrs later, it's at 15%. I haven't use it much except to check a few emails. 2hrs and it only drained 2%.

edit2: 14:26hrs total, 3:44hrs display on. I got bored of waiting so I was playing with a few things and it eventually shutdown.

I'm not sure but for me it seems like every time I flash another kernel and wipe caches the battery get worse. Could be my Recovery (the touch one ..TWRM? not CWM) the cause?

Charged both Nexus 7 and Nexus 4 to 100% before bed and when i woke up saw this surprisingly different results. Yes i know that my Nexus 4 had mobile data on and few messaging app running... But can it really eat that much of a charge in 8 hours?

This isn't totally real since I haven't activated my phone and it has been on airplane/wifi-on the whole time, but I am coming from an Evo 3d.

I am not posting the pictures since no one uses their phone with airplane mode (though I had brightness at 100% for about half that time) all the time so it isn't a real use case, but even so, I have to say that I am completely taken aback with this battery life.

The power manager service is basically a placeholder that an app uses to tell the phone to stay switched on. More info >> http://developer.android.com/reference/android/os/PowerManager.WakeLock.html

Usually its a combination of several small partial wakelocks that BBS groups under the PMS wakelock. Under BBS, you need to take a look under "partial wakelocks" to find out which application it is.
