App drainimg battery?

Bought the vibrant 4 days ago. Flashed it 2 with the Obsidian ROM. Getting great battery life from it too.
Had some free time on my hands yesterday and went on an app downloading rampage. In two hours of light use today my battery has dropped 40%!
How can I identify the source of the power loss?

Media hub always seems to start itself and does drain some. Have you reconditioned your battery yet? I'm on obsidian v2 and this is where I'm at so far.

19 hours with 23% left, not too bad. I downloaded a boat load of apps, installed even more from backup, played a little bit of angry birds and have been streaming Pandora for the past 4 hours.

I did. Took about 9 hours of constant use to drain the ***** too! Exactly why I dont get what's draining the battery. Task manager and Services seem normal as well. Battery usage itsthe same as yours... :\ FML

What I do to recondition is charge to 100% and keep it plugged in for 5 minutes longer... unplug for a minute or two, plug back in, charge til full again and keep plugged in for a few minutes longer. Continually doing this until it takes awhile for it to get below 100% unplugged. This seems to work better for me than the charge, clear battery stats, discharge etc.. and doesn't take nearly as long.

System panel is a great app to monitor how much CPU an app uses.

[Q] Nexus 4 battering keeps discharging and recharging while plugged in

Hi everyone,
I searched the forum for a satisfactory answer yet I don't seem to find one so I'm going to ask here...
I have the habit of plugging my Nexus 4 as soon as I get home, keep it plugged overnight, and unplug it the next day when going to work. About two weeks ago I noticed that occasionally the phone indicates that the phone is fully charged yet, some minutes afterwards it indicates that the battery is at 98-99% and is charging again. I was quite intrigued so I started using some battery applications (e.g. Battery Widget Reborn) and I now notice that the "problem" is quite frequent and happens every single time the phone is plugged (I tried withe the original USB cable that came with the phone as well as with other cables). Attached is an image showing the weird pattern that I'm having...
Does any one have the same problem ? Anyone cares to explain to me why this is happening ???

Isn't that done on purpose? You don't want to keep charging at 100% so the phone discharges after reaching 100% for a while.

When 100% is reached, the battery, for the best of my knowledge, is not used... Therefore, I find that it discharges very very quickly for an unused battery !

Mine does that as well. I thought that was normal?

It's Normal as phone batteries reach 100, discharge a bit and stays there. Btw ROM + Kernel?

Just stock Android 4.2.2

How quickly it uses that small amount of battery that kicks it back into charge mode is going to depend on what you have running and syncing in the background.

Android system & android os battery drain

Android system & android os seem to be draining my battery quite alot. An unusual amount. Anyone have any idea why?

20 Hours at 63 percent? That is outstanding battery time..
I dont see why your complaining.. I get close to 2 days on my battery with average use..
Looks pretty normal to me.. In fact better than most IMO

But the Android os and system don't start until I actually use the device. It's only 2 hours on screen time

Your battery drain might be due to google play services and other apps running in the background

[Q] Is this normal battery drain?

Ok guys, I keep hearing people ranting and raving about this phone's battery, however I feel that mine is either faulty or everyone else is exaggerating. On a typical day, of normal usage, heavy web browsing, occasional 10 minute game session, I can get about 4 hours screen on time, and about 14 hours total time before it's dead and I need to charge. I have minimal wake-locks now that I've figured the majority of them out, and keep location services on device sensor only. My device is deep sleeping more than being awake, and will last quite a while while asleep, battery doesn't seem to abnormally drain while asleep. Every time I've been able to track it down to a wake-lock issue if it has.
It's draining very fast (it seems) while screen is on though. Wifi calling is almost always on the majority of the time.
Any ideas? Is this way off? Or is this the norm?
I've done the usual factory restores and all that, and still no improvement.
Thanks!
Example:

Are you using a custom kernel? You could try dorimanx's and heavily skew the CPU towards a lighter load
I used to get 4h on screen time for quite a while, but k realised that it was cos of 4G @ and the way I used my phone. If you read a lot and hardly launch or close anything the battery life gets better very quickly
Sent from my LG-D802

That seems about right.
On stock I get between 4 and 6 hours screen time and about 24 hours on battery. Being on WiFi rather than 3g helps a lot and turning down the screen brightness.

Do you guys have similar averages? (Seen at bottom of image)

6.0 users post your Android OS usage

Hi Guys,
Do I have an issue with my android os? Seems to be keeping my phone awake and downloading a lot over WiFi. I have no idea why, but I think it's killing my battery life. I am lucky to get 4 hours SOT.
Post yours for comparison

How did you update? Did you fresh install or update over lp?
Yesterday it took me 8 hours to use 7% battery

Yes true, the screen shots are from the same day and why would the battery percentage matter? the battery graph is to show how android os might be keeping my phone awake even when the screen is off.
it would instead be helpful if you could tell me what your Android OS usage is? Or how you get such good battery life?
I did a clean install using flashtool (wiped everything) with the RU firmware.

Do you have Google backup on?

Yes I did have it on. I have turned it off along with uninstalling Facebook and turning off google now. so I will see how my phone performs today..

I have the same issues. Yesterday my screen on time was 2.5 hours and the Android OS consumed most of my battery (more than screen) keeping my phone awake for more than 7 hours. I barley made it through the day

I performed a full software repair via PC companion and cleared the cache partition too. I am presuming it might be that because i am essentially "starting again" the phone has to re-adjust to my usage patterns.
But it should not affect the battery life by that much! I am so mad about this update.

my android os is 25% active
it seems like the radio mobile active bug is gone in MM, but we have now a "android os active bug"
