very very wrong battery readings.....
happens lots of times after flashing.....weirdest thing that was happening to me was battery rapidly falling from 50 to 30% and than slowly growing to 40%.....

Yes, I have to agree. This has also happened to me. I have actually had this happened when I turned my phone off one day. Before turning it off it had 60% battery, after a minute I turned it on and it said 20% battery. Also, has it happened to you that you charge it leave a couple of hours and when you unplug it rapidly falls to 70% or less? LOL! But it is nothing a full charge and batterystats.bin wipe wont fix.

Wiping battery starts has nothing to do with reported battery percentage. Similar results can be obtained by setting your phone face up on the coffee table, watching any random show on tv, and doing Zumba for 30 minutes. In other words... none.
Battery stats, which is only a list of the apps that have put a demand on the battery, is already cleared each and every time the os is rebooted

This is what I have read on the XDA forums and it has worked for me.
Completely charge your phone to 100% (Full battery charge) without unplugging. Once it is charged, without unplugging it, reboot to recovery and wipe battery stats in the ADVANCED section. As soon as your wipe it, very quickly unplug the phone. (as fast as possible). Once you do this, reboot your phone and completely drain it to until it turns off and you cannot turn it back on unless is plugged. Once it is drained charge it completely full withot unpluggin it or turning it on.(Best time to do this is at night, since you are probably not going to use it while you sleep). After that just use it daily. You have to give it a couple of days so the battery syncs up. Hope I helped out!

No offense, but what you have read is incorrect and is rooted in a misunderstanding about how the os and li-ion batteries work.
1. Wiping battery stats does nothing pertaining to charge indication. The file cleared is an already blank file that lists nothing more than a list of the apps that have consumed power. This file is cleared by the is on every reboot already.
2. Completely draining the battery shortens its serviceable life.
Any "results" that are seen by doing the above are merely attributable to the placebo effect.

Hi there, just wanted to check something out, I use automate it to switch my nexus off at night, but once booted again the battery history details start again meaning I'm not getting an accurate reading of how long the device has been going for on a charge. Is this normal or does someone know of a fix? I suppose i might just not switch off at night as battery drain is pretty minimal.

Hi guys. Need some help. Very happy with my nexus 4 but, and its a big but, i am having some serious issues with the battery. I am struggling to even get 2 hrs of screen time on my nexus 4.

What kind of apps do you have?? Like apps that you think might drain some battery. Also use betterbatterystat app to monitor what's waking your device.

With stock, around 2 hours of screen on time is typical. You can prolong the battery life by disable Google Now, location service, email sync, Playstore auto update, etc. Check your battery stats (try better battery stats from the store) to see if any third-party apps drain your battery.
The better way to do it is to unlock bootloader, root your phone then flash a custom kernel. I recommend franco.Kernel. 3-4 hours of screen on time is typical with franco.

Might as well flash a custom ROM with it if you're going to use a custom kernel IMO. When a new OTA, OP will have problems updating to it because he is using stock + custom kernel + custom recovery.
Here is how to fix your battery problem.
1. Turn off location access in Google Maps settings.
2. Wait about a week for the battery to go through its charge cycle 6-10 times. Let it get as low as possible without the battery dying (this is really bad) and be sure to let the battery sit at 100% for atleast a half hour or so when fully charged.
Each day you will see your battery life increase and when done, you should be getting around 5 hours screen on time.
Well dramatic change in battery life as displayed below. Now after having a read in several topics it seems like a fix is to have the wifi on. How strange as this goes against the ethos of all previous smartphones i have owned i.e. wifi on drains battery. I have uninstalled a few apps and also switched of location access, so to be sure that the fix is wifi related i will switch wifi off the next time i do a full charge and see how that behaves. By the way android os is way down in battery consumption now.

I've seen people here and there say they've seen this too, but no one seems to have an answer. My battery isn't lasting until work ENDS, a far cry from when I used to plug it in after work, at home, at 20-30%. It just randomly started happening.
Noticed this on both 4.2.2 and 4.3. I've tried .48 radio and .83, stock and PA, stock kernel and Franco, heard it's common on CM also.
Anyone actually know anything about this? I'd love to last an entire day not having to turn off sync when I'm not using my phone, and other battery salvaging methods.

your android os looks normal. seeing that you didnt use the phone much, your screen on percent is lowered. since your screen on percentage is lower, all others will appear higher than you would think they should be. but if your screen was using 50-65% of the battery as it would for normal use, then your other percentages would be lower. anyways, your android os is normal. what i would look for is an app in the background behaving badly, or disable a notification or two if you have many. if you have root, i would install greenify and then greenify a bunch of apps.
my android os usually hangs between 4-8%, but my screen is usually around 60%(with heavy use).

I think the proportions seem right but I've never had 1-2 or more HOUR wakelocks, it just caught my attention.

i never look at wakelocks, that is how our device is supposed to work. granted, occasionally an app will create a wakelock that gets stuck, but thats just bad coding on the app by that developer. watching wakelocks will waste more of your time than its worth. take control of your apps instead, dont let them run rampart.
Neither BBS or Wakelock Detector is helpful in diagnosing Android OS battery usage. Most of the time it shows as PowerManagerService.Wakelock in Kernel Wakelocks, and pages from google state that is it a sum of Partial Wakelocks adding to PowerManagerService.Wakelock. But there was one time I had a 15 hour wakelock from PowerManagerService.Wakelock and looking in Partial there wasn't anything really significant, most entries being 20mins or something at the top of the list, 10 minutes on the next, and so on.
Whatever it is, it's particularly bad on 4.3 both on my Nexus 4 and Nexus 7.
So I listened to some music for roughly 20 minutes in the car. Set my phone down to watch TV. Came back 45 minutes later and it dropped ~25%. This is WITH 3.5 hours SOT. android somehow still takes top spot. Help?

Everything was fine after the 4.4.2 update until a couple of days ago. I noticed a heavy battery drain during the night - approx. 20%. The conclusion I made: Android OS is back. The WiFi was on, but the router was off, so I though it might have something to do with it trying to establish a connection.
This past night I turned the WiFi off and left the 3G on. 10+ hours of wakelock from Android OS and 30% drain. So, what am I missing here?
The worst part is that those f"%^* from Android developers team has disabled any reporting from the running processes in the latest version.

You can use the stock google app to find what google app is running during the wakelocks. Just go into Settings -> Apps -> Running tab and see what google process are running. Then download and use "Disable Service" from the playstore to find and disable the suspect google apps.
My phone would stay wakelocked after a call or gmail check all because of gcm_google service. I disable it under Playstore services using Disable Service and my google wakelocks went away. Worth a try.
same problem here
misuse of wake locks can easily lead to energy waste
"Android os" usually is the kernel while "Android system" is, well the system. Try changing kernel, it fixed the issues for me.
Hit thanks if I helped you

Change settings in some apps how frequent they should update. For example, update every 6 hours and change settings in Location to device only that might help. On my phone, I had a battery drain to zero just overnight. I disabled Google+ because I do not use it and in Google Play Services turn location off. I also wiped cache and dalvik cache in recovery and the battery drain stops.

I already switched off location, and disabled most unused apps, yet the drain is still here. Anybody else experiencing this issue?

To check what is draining your system, select in first tab: Partial Wakelocks.

What I meant is not an off screen battery drain, rather it is an onscreen battery drain that is far more quicker than 4.3, with my phone under normal usage having a maximum of like 1.5 hours of on screen time even though idle drain is low.

And I am telling you that this doesn't prove anything.
At same screen, I have much more use for system server in comparison to you, but in real life there is no problem.
So, don't worry about this.
