"Android OS" Eating All my battery!

I have the CDMA Desire. I am running Cyanogen 7 Nightly.
Even on older Cyanogen ROMS (6.1.1) I always had the issue of Android OS taking up my battery. I looked at my phone when i woke up to see it was at 11% even though it was idle all night AND fully charged when i went to sleep. Don't know the problem. Perhaps somebody could point me to a battery efficient kernel? Or help me solve the issue

If you barley use the phone it's logic that the android os will take most of the battery. Do you use taskkillers? If yes, don't.
And about your drain, do you have the wifi sleep policy set to never?
settings-wireless and network-wifi settings-hit menu-advanced-wifi sleep

Task killers? No, they are really more of a myth than anything!
Wifi Sleep Policy is set to when screen turns off.
I also forgot to mention in the first post that it took up 77% of the phone's battery.

I hate to bump, but bump.
I switched launchers to see if that would help, i'll update when i find out

Maybe this?
http://code.google.com/p/android/issues/detail?id=11126
Also, check for programs in the background which are using a lot of CPU (like OS Monitor from the market).
Make sure you wifi sleep policy is set to NEVER! (Under settings > Wireless & Networks > WiFI settings > Advanced

Faulty battery?

one thing i noticed with my own battery drain is that i had my tweetdeck updating every 15mins, prehaps you have things that are sync all the time?
also i saw in a post somewhere in XDA that it is just how the batteries work, the lower battery charge you have the faster it will run out.

Widgets? System info widget literally wasted my battery even when not used. Removed and happy about it. Shame you don't get a refund
Check your widgets in the market if there are users complaining about them.

Cell standby will _always_ use more if the OS is operating normally.

I try to keep my phone from using too much stuff in the background. I have Pulse, Twitter and Google Maps (can't stop it) in the background at all times and can get 2 days usage out of it. Widgets and apps running in the background usually are the culprit but if you haven't got a lot of stuff running in the background then I would say faulty battery.

Android System High Usage

Hi guys,
Anyone have an idea what would cause my battery stats to have very high "Android System" usage all of a sudden. No new apps installed.
Thanks

I'm seeing this get pretty high as well. Starting to wonder... TW really limits the information in the Battery Status dialog. Hopefully we'll get ROMs soon that have more detailed information like I had in MikG.

It has always been a bit higher than I am used to. I just grabbed the new version of betterbatterystats from here: http://forum.xda-developers.com/showthread.php?t=1179809
Hopefully I can use this to figure it out.

Please keep me posted if you find anything

System Panel works really well for me I found. Paid version is totally worth it, too.

Just another thought/question...
I am assuming since it is "Android System" causing such high usage ( I have 5% battery left and android system is 30%), that it cant be an app I installed causing the issue.
It has to be something that is either part of the stock ROM (I am stock, not rooted) or something core to the android operating system. PLease let me know if you agree with my logic that it cant be an installed app.
Just trying to find the root cause at this point or determine if I have to hard reset which I dont feel like doing.
Thanks again

The original SGS2 has an issue similar to this.
http://forum.xda-developers.com/showthread.php?t=1290020
They discovered with it that the processor has to ramp back up to 800MHz to do its pre-deep sleep tasks, in addition to taking longer than normal to do those tasks. So with a phone that woke up often to sync, even limiting the processor to 200 MHz with the screen off, it still spends a considerable amount of time at 800 MHz. I don't think they have a fix, but you can work around by limiting the amount of syncing the phone does while sleeping.
Don't know if this is related, since TMO SGS2 doesn't use the Exynos.

Thanks for the reply. My problem is that the battery usage for android system used to be 5% or less and now out of the blue is 25-30%.

Did you change any sync settings? Setting up an email account or maybe a widget to sync could do it. The phone has to do a bunch of system related tasks when it wakes up and goes to sleep, and those fall under "Android OS", so even if it is waking up to sync for an app, the system still has to do stuff, and more than usual when coming out of sleep. Like the other thread said, the original SGSII does all these things at a far higher clock speed than it needs to, and takes longer than most phones do.
I myself don't have the phone yet, nor do I have an original SGS2, but you could look up much of the same information the gentleman who wrote up the OP in that thread I linked to see if the issue is related.

I was so annoyed with this issue that I decided to do a factory reset. I dont think it helped.
So far after being off the charger for 2 hours....I sent 5 texts, browsed web for about 5 minutes. I am down to 87%. Display time is 46%, used for 18 min and android system is 17% with stay awake time at 3 minutes, and there are other items taking up battery at 5% or less like cell standby, android os, market
Does this seem normal, I never rememver android system taking up over 5% even with little usage. I am actually pissed because I would have thought that a factory reset would have helped for sure.
BTW, I am only syncing one acct, Google

I've been watching with betterbatterystats for a couple days now. I've got Skype running in the background so I expect that to use some battery and cause some wake ups.
But it has turned out that location services and updates have been doing a lot more, as much as 7000 in one day. They show up as something related to Maps, but I think that it might be Latitude. So I have disabled that location tracking. We'll see if it helps, there isn't much more using my battery. It is just something keeping it from deep sleeping.
If this doesn't work I'll look at other location apps like weather and such. I already uninstalled Accuweather after reading about how they transfer your location tracking information over the Internet unencrypted!

How can I track down my battery drain?

Leaving my OP in place, but I have rewritten the description with much more detail and pics here
http://forum.xda-developers.com/showthread.php?p=25401417#post25401417
I suggest skipping to there.
I am looking for general tips here. E.g., not asking you to diagnose my specific problem so much as give me ideas of what else to check or try.
Lately I have had unexplained (to me) battery drain. Yesterday I lost about 25 percent in an hour while the phone idled. It is not a constant thing, though. I can go an hour and loose 1 percent then loose massive amounts in the next hour.
Now, i have searched, but I have not found anything that applies to me.
I have:
Tried a different radio
Tried a different kernel
Reflashed my rom
Phone is entering deep sleep according to cpu spy
There are no unusual or excessive wake locks according to better battery stats
No apps are using a lot of battery.
I am in a low signal area at work, but putting the phone in airplane mode and dissabling background syn does not stop the drain.
Ideas?

might be your phone is loosing signal? i would check the battery stats in the settings menu to see if you have a poor mobile signal.

I do, and on reflection it is a possible culprit since I added it recently.
Didn't occur to me since it was producing no wakelocks and the battery stats did not showing as using much battery.
I shall turn it off for a bit and see if that helps. (unless there is some other way to test if it is the problem first.) I am off to the search button!

This is from yesterday when i set it down unused for about 90 minutes. The amount of wakes seems liek a lot, but it is similar to what i see when i have far far less drain, so I don't think that is the problem. I didn't get the app list screen, but out should screen as the only major drain with about 2 minutes.
I know it is shows poor signal strength, so immediately after that shot I put it in airplane mode, turned of sync, and rebooted. The battery continued to drain and graph had the exact same slope under those conditions. (Forget to get a pic though.)
Sent from my jitterbug using tapatalk.

System panel paid version with monitoring enabled is the best for tracking apps using CPU.

OK, still working on this.
To recap:
When the screen is off, and no apps are running I sometimes get inexplicable battery drain. This is occurring under conditions when I should be experiencing little or no drain at all. I say this becuase:
The screen is of and no bakground apps are running
the phone is NOT awake and IS entering deep sleep (as confirmed by cpuspy)
there are no unusual kernel or partial wake locks
there are no apps listed as using unexpected ammounts of battery
This is not a universal problem. The phone *often* behaves as expected. I can leave the phone off for an hour and see a 1% or 2% drain, and I am happy with that. However, sometimes, randomly, it goes nuts on my.
This graph from a few weeks ago shows what I mean. Look in the green box. The phone is sleeping, and the screen is off. The graph starts as a flatline, then, all of a sudden, it begins to drop precipitously.
Here is a graph that shows the battery dropping at the same rate whether the phone is awake or sleeping:
I have gone the following to try and narrow the problem down:
Done a completely fresh install of my Rom including a system wipe.
Tried two kernels (the aokp default and several relases of Franco's
Tried a different radio
Activated and installed a new sim card
I have come to suspect that the problem is network related. When the problem starts, sometimes going into airplane mode and back and/or toggling 2g only temporarily fixes the problem.
I suspect that something is happening with my connection to T-Mobile that keeps the network running and draining power. This is pure speculation, but it is all I can think of.
I installed juice defender (which I had not been previously running) and noticed the that, sometimes, it didn't turn of data when it should have. I also noticed the following two things happen:
I do not believe it is a rom problem, since if so, someone else would be reporting this. It might be an app problem, but if so the app is draining battery without a wake lock and while the phone is in deep sleep.
It is not exchange (as was suggested in this thread) since it continues when I ev my exchange account.
I have no idea what else to do or try.
Since it happens at random and takes a while to identify, uninstalling one app at a time to test for that could easily take months to narrow down a misbehaving app.
I know it is not a hardware issue since last month I got this:
That was with AOKP and Franco (earlier versions obviously)
I have google searched till my fingers bleed.
I am a long way form being an expert, and I suspect I may have overlooked something obvious.
Please, any thoughts??

Damn you definitely have a major issue and I don't know what it could be. But when my phone sleeps itstays dead flat with no awake bars, and drops 1% every 3 hours.

1. Calibrate battery
2. If you really wanna find the problem, install the rom with no mods or apps and run it and see if it still happens. Then add back each mod/app one at a time

While I appreciate your effort, this is remarkable unhelpful for the following reasons:
1. "calibrating" the battery is a myth and doesn't actually do something. Even if it did, it would not explain the symptoms I have described. I have been around xda long enough to know it is the knee-jerk reaction to any battery question, but it is not relevant here.
2. Since the problem occurs at random, and sometimes takes hours to show up, (For instance, last night I charged to full and tried to catch it happening. For 4 hours nothing happened, it behaved perfectly. Then I went to bed and it immediately started to fall and was dead by morning) and since I have over 100 apps, your suggestion could easily take *over a year* to follow. Believe me, I have thought about it, but I started this thread hoping for ideas that would allow me to avoid it.
Here is that chart for last night.
I had about 1 hour and 30 minutes screen on time with 65% left when I went to bed. When I woke up, phone was dead.

Mine often does that. But sometimes it doesn't. It is the fact that it happens seemingly at random that makes it so annoying and hard to track down.

I would replace the battery
One thing you haven't rulled out is that the battery itself is bad.
Have a friend you could swap with for a day, or at least long enough to see if the problem follows? If your battery drops on their phone that is also a good indication.

The thought has occurred to me, but unfortunately, no, I don't have a friend I can swap with. And really, since I have had the phone less than 3 months, the battery *shouldn't* be bad, but yeah, defective products happen.
If I cannot find any other cause I will likely order a new battery and see if that fixes it.

1. yes battery calibration does make a difference.
2. ok, so an app can't run a process at random? especially when you have "over 100 apps"? Run the rom stock and see if it still happens, or even run the stock rom/kernel. if you don't want to try this then why are you asking for suggestions? christ

We'll of course it can. That is kinda my point. If I go one app at a time waiting for it to "run a process at random" I am talking literally MONTHS of testing. I would have to wait many hours, if not days after installing or uninstalling an app to be sure whether or not it made a difference, then move on the the next. This is simply not an option. I started this thread in hopes that a realistic and doable solution might exist that I was unaware of.

Sorry to have put you out so much.

You mentioned you recently installed exchange sync. Did turning off sync remedy this or have you not tried disabling all sync features?
One other thing to check is the background data usage of your apps. You'd find this under 'data usage' and make sure you enable the wifi tab so you can see data usage on wifi.

S3 Massive battery and "Android System" usage with and without charging

I'm having a problem with my Samsung Galaxy S3 (rooted, but no custom ROM) through AT&T where it's losing battery power at a much higher rate than normal every once in a while.
Specifically, today, I was using the GPS feature and charging it in my car, and yet, even though it said it was charging, the battery continued to lose charge. Also, in the past, the phone has lost charge very quickly, and when I check the battery usage, "Android System" is very high on the list, up to 60% (with "Screen" being at 11%, which is usually the biggest culprit for me since I leave the screen on a lot). One time, I went to bed at around midnight and had forgotten to plug in my phone. When I woke up it was off. I turned it back on and looked at the battery stats using 3c's Battery Monitor Widget and saw that it lost charge quite slowly until about 5am, when suddenly the usage went up dramatically, and the phone went from about 60% to 0% in the course of an hour and a half of non-use.
Because this is not a problem I can reproduce on command, I'm not sure exactly what application/process is causing it. Does anyone have any suggestions or has anyone else experienced things like this happening before? (Besides me having to pay for the "betterbatterystats" app?)
Edit: Also, "Android System" sometimes is sometimes listed as "gsiff_daemon" in the battery stats, and within 3c's Battery Monitor Widget, Android System is separate from "gsiff_daemon", where gsiff_daemon's usage is almost 15 times the usage of Android System.

Checkout this thread to see if the gsiff_daemon is your problem. tl;dr when the system is hot and tearing through the battery, go to system settings -> Developer options -> and check Show CPU usage. If gsiff_daemon is the top or second highest on the list, then that is your problem. To solve it for the moment, use system tuner, or something else, to kill gsiff_daemon. There is no permanent cure at the moment, other than to delete gsiff_daemon. Both of those fixes require root, the non-root fix is to reboot.
If gsiff_daemon is not on the list, then something else is the problem, but Show CPU Usage should give you an idea of what system process is running hard.

Samsung Push problem
J M L,
Thanks for the information. I'll do that if the problem arises again. However I also did something else that looks like it may have been the solution for my particular problem, which was disabling the "Samsung Push" service in the Application Manager. So far, my battery life has gone back down to very reasonable levels.

Interesting, I installed "micro cpu monitor" shows thin line at top of screen showing both cores.
I haven't had this happen for some time now but after playing with google play and maps downloading offline maps etc I noticed my 2nd core pegged out.
Having seen this in the past & ignoring it I now realize that majorly drains the battery as well as it getting warm.
A simple reboot seems to be the only thing that fixes it. Clearing ram and closing recent screens dies nothing to clear the "cpu jam".
If left alone, it always shows the culprit as "android system"
As to what part of "android system" I don't know.
But until we figure this out for good, that little micro cpu monitor. App is sweet for peace of mind to know all is well or whether a reboot is needed. For what it's worth, I also noticed that after the event, that my auto rotate to landscape was mysteriously unchecked?
If it jams again, I'll have to see if it gets unchecked again, unknown if there is a relation.

I read the thread about gsiff_daemon culprit. I had it listed as a possible battery drain culprit. The thread says the issue may happen after a hot reboot...which I did have. Killing gsiff_daemon was not immediately effective. I renamed the file so it wouldn't get used...like the thread recommended. I had to reboot to get normal battery drain back and have yet to see the issue again. But i wont know for some time...or maybe when/if i get a hot reboot...which is really rare. Do yourself a favor, and buy better battery stats. Its a must have tool...and it's not expensive.

so with some trial and error i found some resolutions ..
first, i used Watchdog and it told me that the media services is killing battery too.
so doing a full wipe does not always fix this.. but what does, is reboot and wait about 1 hour charging and it will calm down. this was just something i noticed. so what i did is wipe out my SD cards, both of them, cleared them out 100% formatted the External SD, and used recovery to format the internal. From there it seem to work, i put my stuff back, and it seems ok.
problem is, when you install a lot of rom's and have bad reboots some files get messed up and you have to do it all over again..
problem was with AOPK, CM and TW roms.

My experience with froyo/gb/ics is that things have been getting progressively better over the years. But with each so called UPGRADE of an OS or even APPS, we often have to deal with bugs or incompatibilities. I am eager to upgrade to a stock based JB soon, but wisdom says, for 20 things improved, there will be 5 things broken....or hurting in some way. Early adopters suffer the most as usually these issues get ironed out...most of them.
BUT...these stuck drains...wake locks etc., it seems they will happen when they do no matter how many issues get fixed. Over the years, I've had random standby drains caused by Maps/Nav. Maybe it's ok for months, then after a particular update, it's back...and unpredictable. The YES...a reboot, just like with a PC, is a quick short term workaround.
Finally, with the App CURRENT WIDGET, there is a provision to watch for high drain in standby. It watches MilliAmp (ma) readings over time..to determine if you have a rogue drain. That's different than monitoring the CPU. (Some drains do not cause much CPU activity) BUT UNFORTUNATELY, that app won't work with our S3's because of a lack of hardware support. Works great with HTC and many others. It's a bummer because I used to use it and have my HD2 reboot if a 15min consecutive high drain was recorded in standby....thereby saving the battery and usually killing the bug.

Crapppp
Jellybean didn’t solve it. Gsiff_daemon just popped up for me. Just renamed it AGAIN.
Hopefully it won't pop up again

[Q] 4.4.2 Battery Life issues - less than 25% total life compared to previous version

Hello, new to the forums here. I recently updated to 4.4.2 on my LG Optimus G Pro and I went from having a battery that lasted all day, sometimes two days to my phone being dead by the time I get home from work for the day ever since the update.
Two days ago I had 1hr18min of screen time within a 6 hours off the charger and the phone was at 15% battery life left. Today, I had 13 minutes of on screen time and at the end of my 6 hour shift my phone was at 40% and dead a few hours after I got home. I have GPS, bluetooth, NFS all disabled and my brightness set to 30%.
Any help would be greatly appreciated, I'm thinking of doing a factory reset and just not updating to the new version of android when it prompts.
Thanks

Hello, new to the forums here. I recently updated to 4.4.2 on my LG Optimus G Pro and I went from having a battery that lasted all day, sometimes two days to my phone being dead by the time I get home from work for the day ever since the update.

Get betterbatterystats and see if you phone deep sleeps. If not then check what the wakelocks are in partial wakelocks. If it's a kernel problem maybe you need to flash a different kernel.

i am running stock phone. it is not rooted or anything

Same exact battery drain problem. Im on stock e980 rom (rooted) with no custom kernel.
Gsam battery monitor app is showing the kernel as keeping my phone wake for the entire time my phone has been unplugged.
The problem seems to come and go though. One day itll be fine, but another day the battery will be sucked dry fast.

I'm running stock rooted for e980 and have pretty good battery life .... Try clearing Google play services data and rebooting ... Check and see what's draining your battery mol its pretty easy

I'm also running stock kernel, and have great battery life on kitkat. Just reset your phone to factory defaults

I've done this twice in the past 3 days....
I'm sick of having to set up my phone over and over again. And this is a new phone too. I just got it Monday under warranty because my old phone broke.
It's getting annoying. I used to get 14-17hrs+ of battery life (casual use, usually ending the day at 30-50% too, so I never even reached 0%) with my old phone on Jelly Bean. Now with Kitkat, I get around 6 hours if I'm lucky! According to Wakelock detector, my phone is awake 85%+ of the day! All it points to is Kernel (Android OS). I see lots of Wlan_wake triggers too, so I suspect wifi, but even with wifi off, the drainage still occurs. And I only have a 2GB data plan shared between 3 people, so it's not like I can just use data all the time either. I actually NEED wifi.

do you have an SD card installed? Maybe you can try to remove that and get rid of all other media from your phone storage. Might be a media scanner problem? Or maybe you can try to disable auto sync, and check if Google play services is the culprit.

The media scanner usually shows up in the battery stats window though, and it isn't. I've had a corrupted SD card on my tablet once before and it caused media scanner to go berserk, but the Mediascanner entry appeared under Settings>Battery as the highest battery consumer.
In this case of my phone right now, it is Android OS in Settings>Battery. According to Wakelock detector, GSam, and BetterBatteryStats, it's more specifically Kernel.

Have you tried reflashing your firmware, instead of just doing a factory reset?
I assume you are rooted since you are using BBS and wake lock detector on KK. Why not flash a custom rom?

Hi i had the same problem as you but i started digging inside the system of the phone i found the problem but you will require root access. If you have root you have to delet a lib file tand it carrier iq wich run in background and drains your battery the file to delete is libiq_client.so do that and you will see an increase in battery life

I did this on Tuesday or Wednesday.
... I messed something up on my phone while trying to install a custom recovery, so I was basically forced to reinstall everything. I'm on stock ATT e980 ROM (on an E980) + root. I reflashed the Jelly Bean tot file and then did the OTA update with no apps installed.
On the phone that got warrantied, I had flashed the E980 kitkat backup (now has a flashable version too), and the battery life seemed to be much better on it for about a week, and then the issues started there too.
I just rebooted the phone into recovery and wiped cache and Dalvik cache. Many people on Kitkat are reporting that this helps, but only for about 2 days then the issue returns. Obviously, I want a permanent solution.

I just tried this right now. Will see what happens.
Will report back if I see anything noticeable.
How would this this battery though? Like, what does it do? Are there any adverse effects to removing it?
EDIT: BTW, I know you weren't addressing this at me, but I'm still trying it LOL

I didn't see this part of your message, but I just had to respond lol
Yes, I'm rooted and I absolutely hate custom roms. They take out all the features of the phone that I originally bought the phone for, like Smart Screen, the IR remote (yes, I know it can be ported), and the quick memo button. Plus I used custom ROMs on my old SGS2 and they always caused me tons of problems. Crashes, overheating, random reboots, random SODs, etc etc etc. Plus I hate the AOSP feel. I know it's true Android, but I just don;t like it.

I'm still getting more than usual battery drain, but it is better now.
I just got a replacement OEM LG battery, so I will try that to see if maybe the battery is defective. When I got my phone replaced under warranty, they didn't have batteries in stock, so they just gave me back my old one and ordered me a knew one. The old phone was overheating a lot too, so maybe the battery is bad.
UPDATE: OK, MUUUUUUUUUCH better battery now!
I put in that new battery and "recalibrated" it by draining it to 0% and charging with the power off. Once it reached 100%, I let it charge an extra hour, unplugged, and started up the phone.
I also installed Qualcomm Snapdragon's Battery Guru. I set it up so that it's mostly managing app syncing, but I also set it up so that it will not rely on location services to turn on/off my wifi. I don't want to leave my location services on all the time. I don't know how it is on Kitkat, but on older Android versions (ICS and GB), leaving GPS on was a huge battery drainer! I still treat location like it was back then.
Anyways, it will take a few days for the app to learn my usage patterns, but it's already helping by making certain apps only sync when I open them, etc. I suspect that all the wlan_wake wakelocks are being caused by auto-sync but I'm reluctant to turn it completely off since i rely on it to sync my work schedule, calendar, etc between my phone and tablet. I just wish there was a system setting to allow auto-sync to run every X hours or something. I really only need the sync to run every 6 hours or so.
It's been about 35mins now with 6mins of screen time and the phone is still at 100%. A few text messages and the installation of Battery Guru too. This is normal and how things used to be. After a while, the phone will most likely go to 99% and then have faster drain, but it shouldn't be so rapid like before. Earlier today, after 30mins, the battery would be at at least 95% or lower by now! After a full day, the battery usage graph would should a 45 degree angle too! It used to be an almost level, very gradual angle instead.
I should also mention that for a while, I was using a Zero Lemon slim battery (3150mAh). I bought it because of all the hype Zero Lemon was getting here on XDA, but I really regret it now. I used it for 2 weeks (1 week on my broken phone and 1 week on my replacement) and the drain wasn't consistent, even after several calibration attempts. It lasted me all day though, but I'd be stuck at maybe 3% for like an hour, then while in deep sleep, the battery would "magically charge" to 6%.
After I swapped back to the OEM battery, I don't think I recalibrated, so I wonder if my phone thought I was still using the Zero Lemon.
I'm planning to return the Zero Lemon.
UPDATE2: It's been a couple hours now and the Android OS is starting to retreat from the #1 slot in the battery consumption list!
Screen is #1 now and Android OS went from 65% usage to 14%! :good: :good:
UPDATE3: :crying: OK, it's broken again. I didn't do anything to the phone, but when the phone hit 50%, I left it alone for 2 hours and the battery drained 30% while it was supposed to be sleeping. Android OS is back up to 80% usage!
Wifi on, Location off, Bluetooth off, auto-sync on. I'm trying auto-sync off today to see if there's any dramatic improvement.
UPDATE4: I might be on to something now. I noticed 2 things: 1st, when the screen is off and the phone is SUPPOSED to be in deep sleep, the back of the phone stays warm to the touch. It wasn't hot, but it was warm enough to be noticeable. 2nd, I had System Tuner installed yesterday but uninstalled it this morning. Despite uninstalling and rebooting, the phone was still draining battery fast (I still lost 25% in 2 hours today!). I noticed that System Tuner had added a script to System/etc/init.d, so I deleted that and rebooted. Now the phone seems to be sleeping (says so in BetterBatteryStats and WakeLockDetector), and the back of the phone is COLD to the touch when doing so. I took a shower today (I take fairly long showers too LOL), and then checked my email, and the battery life didn't decrease at all during that time while it was asleep.
Obviously, I need to test this throughout the day now, but this is definite progress, if not the solution.
Also, on my warrantied phone, when I had the Zero Lemon battery inserted, battery drain was high (battery's fault), so I installed System Tuner then too, trying to tweak the phone. After switching back to the stock battery, the drain remained, but most likely due to System Tuner's script.
Then when I got my replacement phone, I ALSO installed System Tuner and of course, I got battery drain issues! I factory reset, but did not install System Tuner, but the problem still remained. However, it probably remained because the reset doesn't remove system files, so this script was still in the init.d folder.
FINAL: I ended up flashing the stock ROM again (I used Eazy Kat 1.0 this time). My phone began bugging out on me. Random crashes here and there, mobile data randomly disappearing (no LTE/4G/3G at all), and worst of all, people were having difficulty hearing me during calls. Reflashing seems to have worked perfectly this time. *knock on wood*
FYI: The last flashes I did, I used .tot files to flash back to stock Jelly Bean and then updated to Kitkat via OTA.

I stumbled across this post and tried that fix. I'll check back in later to see what it does.
