Hey guys. I know XDA is filled with battery threads, and I've done numerous searches around the forums and across the internet. Nothing seems to be helping me.
Recently, the battery life on my Nexus 4 hasn't been so great. I've attached a few screenshots of GSAM. Any ideas on what is causing the significant drain? I'm down 15% in 1 hour and have barely touched my phone. Using stock 4.4.2, rooted with some Xposed modules (none of which seem to correlate to being installed near the time of the battery life becoming crap).
Here is a dump from GSAM as well: https://www.dropbox.com/s/z6uo3q5059mcwhu/02-26-14.txt
Edit 2: After just over 4 hours, I'm down to 50% with a ton of wakelocks. This is the part that I can't find any helpful info about. Here's the new log: https://www.dropbox.com/s/tv01k9tbmo38gbv/02-26-14 2.txt
Edit: Trying to fix the images yet again:

You know, I haven't ever on this device. I had on my Samsung Captivate and Nexus S, but have yet to use any sort of battery calibration on my Nexus 4. And now that you mention it, I've had some strange behavior with going from 35% to 25% rapidly, rebooting, and then having it at 30%.
Do you think it's worth a shot? If so, any good apps for this? When I did it on old devices, I just used the CWM option to delete battery stats and then charged/discharged fully. Seems that TWRP (which I have installed) doesn't have this option.

Thanks a lot, hopefully this works!
what the app does it deletess batterystats.bin
but google already stated that its just placebo, this file is only for the batteryicon
thats why cwm removed it.
second those wakelocks are just seconds. so its normal
third. do you have any sync service?(skype,facebook,email, or even google) if so
try disabling temporaly
if dosent work you may wanna try the xposed + xposed module called disable critical shutdown
then wait till phone turns off and charge for minimum 8hours
if not
change rom/kernel
if still not
its your battery(if so, and you still have warranty, you can get an rma if you live in a google area or get money back if you live in a area where lg controls,or buy another battery

Hadn't read about it being a placebo, thanks for the info. I downloaded BBS and think the issue is actually the (common) msm_hsic_host issue. It had several hours today. I'm flashing Matr1x kernel right now, so we'll see if that takes care of the issue.

Well that pretty much clears that up, thanks!
Try going back to stock android and check the performance. It can be that one of the Xposed modules is causing you the problem.

I got 26 hours off my first charge from getting Sprint's 2600mah battery off heavy usage. Now i can barely get 6 hours in 50% after i calibrated it. My lesson is, don't fix what's not broken -___- idk why its getting poor battery all of a sudden. I barely even used my phone today. Wth is going on? ;/

Look at your awake time. You have something up a lot. Even when your screen was off you had something running away. If you can't find it do a factory reset and back track your apps. If your rooted its really easy to restore apps, just don't restore data. Start over.
You definitely have a wake lock.
Your phone was awake for hours while the screen wasn't even on at all.
No this is when my battery was good. And that is NOT a wakelock, that is WIFI. WIFI being on counts as awake apparently when i test it.

No, my wifi is on anytime I'm in a wifi area and yet my awake time is not even close to the same amount of time.
It seems like the calibration method you used is what caused you an issue.
It might be that the phone thinks your aftermarket battery is only the stock battery and is therefore only charging part of the battery.

You think flashing a new rom will do? Ive wiped caches and stats before. But i dont have anything wakelocked for sure. I checked betterbatterystats for locks and my current awake and screen times are on par. However what can i do to make my phone recognize that i do have an extended battery in?
Simple recalibration. Easiest way is the battery calibration apologize. I lol when someone recommended it to me as I have always wiped the same file thru root explorer but it does the job. Very simple. U should really recalibrate after any battery change where mAh are dif
And wifi does not cause wake locks. But unless you were playing music the whole time that's a lot of awake time for the screen to be off.

Glad it's been fixed for you.
You should definitely watch that awake time though.
You were wake locked in that screen shot and that will eat your battery like none other.
I know this has posted a million times.
Without a warning my stock KH1 with CF-root started to have bad battery. According to battery usage it's the android system. Around 40 - 60% sometimes.
I usually had it around 10 - 20%
Also the better battery stats says its caused by "suspend" and "events/0"
Now I've have read this bug over and over by tons of people but I never had it. Always stayed on stock with cf-Root. Didn't have a problem and BAM! there it was
As soon I noticed this I flashed stock back, first to KH1 and then KG6. No difference. And no I didn't just wait half a day to see if it worked with each other firmware or ROM I gave it at least 3 days or at least 3 battery charges.
And so it went on. Stock KH1 with CF-ROOT -> KH1 -> KG6 -> Cognition S2 1.51 -> Exynos 5.4. No difference.
Again I'm sorry of bringing this up. I wouldn't post this thread if I had this from the beginning. I just find it weird that it just appeared.
Maybe it's from my apps but wouldn't the battery usage say anything?
Just saying as well that my phone sleeps when my screen if off and goes awake when I turn it on. No odd awakes while my screen is off.
With regards,
Sven

This is the Android OS bug. I doubt it will get fixed before Ice Cream Sandwich, and even then, it's not sure. Welcome to the club of ****ty battery.
lol, battery is not so bad, anyway, which is the most actual firmware file version??

Did you refresh BatterBatteryStats? Sometimes it doesn't update. If it's updated, then it's not nearly that bad. For me I've noticed that 1m of CPU time is about 1% of battery lost. So for you in that screen it's about 12% lost due to the suspend and events/0 activities. And if battery is at 34% (can't see correctly, too small), then you don't have it nearly as bad as some others.
Here's what I get sometimes when it escalates: (20h lifetime, complete idle)
@OP- You are on the same group with me. I always stay on CF root with Stock ROM and I also never had that AOS bug until last week it suddenly appeared! I posted about it on the BBS thread but got no response usually. The thing is you can't stop it, once it there you just have to live with it. And gradually it will disappear again. Just wait till then.
Regards.

I've never believed in the AOS battery drain bug until I got it myself. And indeed like the others have said, there is no permanent way to fix it.
the best you can do is to try flashing different ROMs or kernels and see which one gives you the best battery life, with or without the drain bug. For starters, you might want to check out the Speedmod kernel

No, there are ways to fix the bug at times, just depends on what causes it. Day one when I received my phone, I had the android os bug. Used to be up in the high 50%+ for Android OS, but then I found out my router caused the issue and now it's always below 10%. I'm also on stock btw, no root or anything.
I've installed the 2.3.5 kernel recently because people were saying it was great on the battery but i'm getting pretty tired of this...
Out of nowhere sometimes like this morning i left the phone screen off since 7.00 am full charge and i checked it now at 11.40 and the battery was at 79%... It has been awake the whole morning. I looked at OS monitor and it might be calendar trying to sync all this time without having a 3g connection or wi-fi... why would it keep the phone awake and try so many times to sync if i'm not under 3g coverage?
I used to get 3 days with 2.3.4. I'm going to revert back. Aweful update...
thanks for telling us
I thought it was calendare but apparently it isn't.
Only after clearing RAM has it stopped staying awake even with screen off.
No idea what this is all about.
How do i discover what's keeping my sgs2 awake?
Tell me about it!
I flashed XWKI8 and I have been having all sort of issues with it. My phone was terribly slow and very laggy. It was getting seriously heated up around camera.
And above all, I took it off the charger (100% battery) 7:30 in the morning and now by 3:30 PM I got no juice left in the battery! It just died upon me.
I think I will flash it back to our trusty KF3 update.
Does anyone know if I can just download it from Intratech's thread and update with ODIN, or do I need to get some kinda wipe package from somewhere?
i'm quite positive you just need to reflash the pda in odin
You have no idea what you are talking about. You start that the kernel is not good. Then you blame the calendar for keeping your phone awake. Now tell me how is that related?
You can't say that something is bad based on one experience.
If you read the replies you would've seen that calendar is not the problem...
And before the update the phone was NEVER awake if the screen wasn't on... So YES i think it's a kernel problem
Nonsense !
2.3.5 battery just fine ... better than 2.3.4
Gives me a full day when used intensive (3-4 hours of surf, mail, talk)
Gives me 2 days if used moderately
About ½% per hour standby
The real question now is... how can i see what is keeping my phone awake???

Search for 'Better Battery Stats' in XDA.
Besides, I don't think it's huge improvement in battery life in 2.3.5 than 2.3.3. I am getting almost same battery backup in recent KI3 which I was getting in previous 2.3.3 KF3. There are plenty of ROM's but I doubt there is any difference between then other than they are dedicated for different regions. It's basically a freaking thing to flash new ROM's continuously.
look at this thread http://forum.xda-developers.com/showthread.php?t=1290020
and check if it isn't the same thing that's bothering you. when you look at the built in battery stats, do you have a very high usage percentage of "Android OS"?
dude I am usin XXKI8 (2.3.5) with chain-fire root kernel KI8..
I have seen drastic improvement on battery life over KF3.. only 2% overnight drain on standby (with data connection off of course). smoother animations.. near zero lag while locking, unlocking, smoother browser.. the only thing that bothers me is occasional lag while opening gallery.. rest is superb..

I had that also, it's a ***** in Facebook app. You don't need to remove facebook app, just go to facebook chat and log off. I wonder why it's enable by default from facebook if they know this thing is going to drain battery like hell.

How?
Very simple : just delete it.
Your battery will thank you soon, and you will certainly stop pulling your hair out.
Anyway, you always can use mobile FB version which is actually pretty good.
Cheers
No need to delete, just use the app and sign out of chat, poor design on part of facebook, but like many others using android, no investigation, just blame the update or the phone......
nah. i did not know how to see what processes were keeping my phone awake. now that i know i'm a happy new man. And i'd also like to change the title of this thread!
I'm noticing some incredibly high kernel wakelocks on my Note 4, which aren't present on my Note 2 (which rules out something on my network causing the problem ).
It's anyone having these? Any idea how the heck I'm suppose to get these lower? Wlan_wake in particular is firing off several dozen wakelocks per second.

get an app called Amplify, aka LiOn Tamer, aka as far as i know dev could be changing the name of the app again as we speak. The regular version is usually good enough, although the donate version takes care of most of the other wakelocks...assuming you are rooted and have xposed installed, if not, good luck.
This app is probably one of the best apps to control wakelocks, the battery life increase is also considerable.
As of now I got 4h34 screen on time in 19h47 of battery life and have 37% left. I'm pretty sure if I wasn't working tomorrow and needed a full charge in the morning I could hit 6.5h of screen on time and an extra 7h battery life before I reach 0%. Stats that are not possible without this app

dont disable it, just make sure you update the app list on it. I also got a N4 on launch day and the update was there out of the box, i dont have such issues though. I'm pretty sure an app is causing this, just gotta know which one. It could be almost any app, check your per app battery usage and see if an app is draining abnormally your battery.
You haven't mentioned this anywhere, but is this affecting battery life?

I've been getting poor screen on time, but these wakeups seen abnormally high (half MILLION triggers in less than 24 hours???).
I'm going to look at packets on my network to see if any are pinging my device for no good reason.
So I bought the phone used for 350 USD. The guy claimed he only used it for two weeks.
Although the phone is great quality, but I think the battery is broken.
Its like drops a percent after other minute use. Anyone please confirm it it's not normal.
Do you know how can I log the battery usage?
Sent from my HUAWEI Y300-0100
From 100% to 70% for 4 hours, just chatting in Internet. Look log in "battery usage " where you can turn on/off "stamina". From 100 to 90 I drown fast. The most long battery life % when it is 60-40%
My phone drops a percent after 5 minutes from 100% and sometimes it takes less time .. but battery life is good

The problem is here when you buy the phone?Try to calibrate battery(there are a lot of methods). The older user probably used wrong his battery. Calibrate and try for another week ...and see the results Do you make a factory reset when you buy it? If you don't ...try it... sometimes factory reset fix batteries calibration problems Sometimes my battery drops like yours but depends what i do.
Yes i did make him do factory reset before I got it. But damn i rush i hadn't, i could have seen total run time.
I read on another thread where it said Facebook app drains battery a lot.
I haven't charged it to 100 percent yet. Will see how long it by doing it.
Uninstalling the Facebook app did make a difference.

Try a hard reset and then flash 4.4.4 again
You should confirm that if the phone is using stock firmware. or you should just flash the stock one by yourself. since you said USED phone.
also if it is battery issue. you should able to get a new one from ebay. and I think there is a video on youtube about open the back panel and change the battery.

Update
Just wanted to post an update.
The About information of my Sony device, non rooted and did complete up to date.
Right now I have it fully charged to 100 percent and have read a few calibration "How-to". I removed it from charged and rebooted the phone. I have install GSM Battery Manager as well.
I still don't know how I can delete battery stats and I think i can't considering the phone isn't rooted. I have stamina mode enabled + low GPU/CPU undervolting option in it.
Lets see how long it last.
