Look in your battery stats and see what is draining the battery.
I know there are a few ROMs that have the 'android os' power drain bug. I don't know the cause or whether a solution is being worked on. It seems the core of many of the ROMs are based on the same things. Kernels, modems, etc.
If it's the android os draining your battery start airplane mode, and then turn it off. Everything should go back to normal.... at least for a day or two.
I've run Zeus and JB-paranoid android. both has this issue. When i ran CM9 i didnt seem to have problems.

If it is not an issue for you, then upgrade to the latest build.
The one you are running is almost a month old now, so a lot of development has occured since then, specially at Scott's pace.
I don't guarantee it will solve your issues.. maybe it is one of your apps. But it definitely would not hurt to update, plus i'm pretty sure you will enjoy it

I'm having same issue and for me, when I restart, ot worked well for a day or two. Whrn android Os is not draining my battery, it spent 1% for 5 hours of stand by. I wanna know if there are permanent solution for this problem.

That's a joke right? 1% in 5 hours of standby is great battery life...think of it this way at that rate it would take 500 hours of standby to die...that's 20 days of standby!
Btw...official specs are 400 hours of standby...so your way above normal in a good way
Edit...think I might've mis read your reply...is the 1% drain when its running good? And what your complaining about is when it drains faster cause of android os?

Maybe slightly less than 1% per 5 hours. However, it was that good. I mean I got replacement phone week ago. So it is brand new battery.
But I'm still having that problem.. Android OS drains **** tons of battery. If I restart the phone, it solves problem for a day. I wonder if there is any permanent fix...
thank you

ive seen that reflashing and doing a full wipe, seems to fix this problem 3/5 times. the 4th person usually has a bad download of the rom while the 5th person has figured out the problem on their end.

I flashed zeus a few times with complete wipes. That didn't seem to help. FWIW, I was using 5.2... not the final version. YMMV.

I am having the same problem also on PA.
I believe several others are as well.

I think this might be what you're experiencing. I've noticed a ~%20 continual usage by system_service on multiple JB ROMs not just PA whenever auto-rotate is on. Try turning it off.

Any ICS or JB ROMs will use more battery than older builds of android. Its one of the small prices to pay with all the great new features. I carry a charger with me at all times. I'm going to get a larger replacement backup battery and I won't even worry about drainage after that
Ps- which cm10 build are you running? The new 9/26 build fixed quite a bit of battery issues...

I'm also running cm10 4.1.1
My battery life can be extremely frustrating some days and can drain more than 10% per hour without use. I have my accounts set to no connection and my brightness is less than 10%
Here is my batter use:
I do look into my apps and find the application Facebook likes to activate even when I don't open it.
Here's my apps that are running as well:
I would love to find a solution for stable battery life. On a good day my phone will drain 30% over a 8 hour period with moderate use. I consider that pretty good.

Excessive battery drain?

Hi, think im about 2 weeks into my ownership of my N5, and over tha last few days ive noticed that the battery seems to drain far quicker now than previously. For example, my phone was 100% when I unplugged it at 8am this morning, and at 12: you can see the drain with very light use. I notice android is using a lot? Is this normal?
Any tips etc?
Thanks

i also have this problem, since 4.4.1 update Android OS is draining a lot

i read somewhere this could be down to fast dormancy??

I have a new "winner" in the battery drain category - this morning, I looked at mine & "Exchange Service" is now #2 on the list when I tap on the Battery.
Can I say, let's see what 4.4.3 is going to bring in terms of fixes & breaking more ...

Well, whatever it was, a factory reset resolved It! Been running sweet since i reset the old girl.

I've been having issues for a week now with Android Os/Kernel killing my battery. Just figured out in my case, it was having the "Enable Battery Stats" module in Xposed. Been running it for a few hours and everything but this Damn Audiomix wakelock seems good

The same in nmy nexus 5
I have the same problem in my nexus 5 after updated to 4.4.3 the use of batery for Andoris OS is around 20 % higher

Inconsistent battery fixed by reboot

I have been so impressed with the battery life on the N5 however the last 2 weeks my battery is dropping 50% in less than 4 hours. If I reboot my phone it fixes this and drops about 10% - 15% in 4 hours.
I thought it must be an app I am opening that is constantly running in the background but can't see anything obvious.
Anybody got any suggestions or advice? I have stopped almost all apps and uninstalled the majority. I don't want to restore factory defaults if I can help it.

Have you checked Gsam? Mine sometimes does that, and the culprit normally is my kernel keeping the phone awake for whatever reason, and a reboot solves it. Not sure why though

Get betterbatterystats and see what your wake locks are.

I have gsam but not really sure what to look for?

I'm not familiar with that. Does it tell you what your partial and kernel wake locks are?

If you go to App Usage it will give you a breakdown of what apps are using your battery

I have this exact same problem. I normally have to reboot my phone when I disconnect from the wireless charger. I don't think that's always the cause tho. I would love to install batterbatterystats but you need root am I'm really trying to not go down that road anymore.
Sent from my Nexus 5 using Tapatalk

I think It's the dialer. I had this problem in 4.1.1 where it would constantly be looking at my address book in exchange.

In my case, Gsam points to the Kernel being the issue. I'm trying out a different kernel, and haven't experienced the same issue.

Massive drain with no wake locks

Hey all
I had a wake lock trigger that was draining my battery so I decided to try and find what was causing it. I turned off all background sync and disabled GPS. I charged my phone to full and then let it drain over night. As you can see in screen shots... Massive drain occurred with no visual signs of the cause. Anyone have an idea?

Did you get any shots of the Kernel Wakelocks and Partial Wakelocks screens in bbs? That's where you would see the culprit(s). Also, do you ever do soft reboots? Some people (including myself) have experienced increased battery drain with no visible wakelocks after soft rebooting. Doing a full reboot seems to fix it.

It's definitely something using Wi-Fi. Need more in depth analysis

I checked those but there was nothing abnormal. I'd done a reboot when I flashed the kernel back to stock pa.

I've disabled wifi and it drained to dead. Going to recharge to full and see what it does off wi-fi. What could I do to see why/if wi-fi is killing it?

You can see it is draining it in your screen shots. Maybe you didn't fully disable the background Wi-Fi usage. "scanning always enabled" for example

Doesn't look like its disabled correctly. Your screenshot shows nearly 8 hours Wi-Fi.
Maybe there is a bug in your settings data.
Not sure if you're rooted or not but maybe a backup / wipe is the best course of action

Here's the current setting. I guess I can factory reset again. I'll try that after this current charge cycle.

You could try booting the phone into safe mode to see if it's a 3rd party app, though unnecessary if you plan on trying a full reset anyways.

Factory reset, no syncing enabled, no auto updates, google now disabled, no apps other than stock gapps installed. Still high android os usage.

while at first it looks high, in reality it isnt(yet). in your screenshot you have only lost 5% battery so far with light use. at this point you really cant tell what your battery will be like with use.

ahh, thats a little better, but itll drop a little more with use. while 20 is a little high, id still classify as normal. really anything up to 20% is normal. typically, after a full cycle, i see android os between 9-15%. but it would all depend on exactly how you use your phone.

i see that chrome(and chrome sandbox) is taking a huge amount of battery for very little use. 21% together, just to respond to xda..

Install system monitor from play store and check CPU freq and number of CPU's online while screen on.

As said above....use the phone normally and check when its almost drained. It will surely be much lower.
If location is on...it will probably be higher than 10% I'd guess. If so....completely normal.
