"Android System" draining battery life running Marshmallow 6.0 - Nexus 5 Q&A, Help & Troubleshooting

So I recently cracked the screen of my Nexus 5, ended up asking the official LG repairer in Australia to replace the battery with a new genuine one as I thought this was the perfect opportunity.
When I received the phone back I had the 6.0 update waiting for me, did it straight away and I was getting amazing battery life. Over 4 hours of SOT. I was thinking this was a combination of a new battery and Doze.
Anyway, since then my battery life has been terrible. "Android System" just chews up so much battery and my phone is really hot all the time from it. It almost always is using more battery than the screen.
I thought maybe a factory reset would work but it hasn't. I've unlocked the bootloader and rooted the phone and I'm not running BBS. I was wondering if someone could take a look to try and help me figure out what's causing it. How can I go from such fantastic battery life to this in the space of a few days?
Here are some screenshots of how much Android System consumes my battery when I've not long taken it off charge. The phone gets really hot when this happens.
Also here are 2 BBS dumps. As you can see, in one, I get 4 hours of SOT and the Android System wasn't eating battery like it was this time. I don't know what's causing it. Turning Google Now off, location off, WiFi scanning off, 2.4GHz only and mobile data off hasn't changed anything. As you can see 'com.android.phone' seems to be using a lot of battery under Process in BBS. Could this have something to do with it? When 'Android System' wasn't eating battery and I was getting over 4 hours of SOT you can see I was listening to podcasts and using my phone a lot and it was fine. I'm hardly using my phone when 'Android System' is draining battery so I've got no idea why this is happening.

Can anyone see what could be causing this? I've got no idea and it's seriously annoying me now. Any help would be greatly appreciated.

Well the first days i updated to 6.0 i had a similar issue with wifi. A couple of days later and now its exactly the same as yours. I have no clue about what's going on.

I wiped the cache partition from recovery when this was happening and turned mobile data off, 'Android System' then stopped draining battery. I think there is an issue with the radio, like the radio active bug in Lollipop. When the drain is there, turning off mobile data doesn't seem to make it go away on its own, the phone it seems needs to be rebooted. Any time the drain is happening, it's once again 'com.android.phone' in processes of BBS that seems to be doing the damage.
Edit: Okay, it still happens with mobile data off. I've got no idea what's causing it.
It seems to happen more when I use Hangouts and specifically send and receive text messages. In one conversation I have about 70,000 SMSes. Could this cause it?

Cell Standby Battery Drain

I've searched about a million times in 900 different threads, but I still can't find a fix to this issue.
I first noticed this when I flashed MIUI onto my phone. I would get cell standby and cell idle at about 40-50% of battery usage each. Display wouldn't even be shown on the usage! I then figured MIUI wasn't worth it to me, so I flashed CM7. I tried both morfic's and faux's many kernels, nothing seemed to fix the issue. If I would turn the airplane mode on, I'd get battery drain of only like 2%/hour.
So I figured there was something wrong with the CM7 port, so I tried g2xtreme and other GB ROMs, same thing. Finally, I just checked a froyo ROM, same thing again!
So at this point I'm clueless and thinking the phone is completely a POS, but anyways. I'm about to nandroid restore stock 2.2 firmware, and try updating through the LG Mobile Support Tool.
But I have my doubts that this will fix it. I'm curious though if maybe I'm getting this drain because I'm with WIND Mobile in Canada? And this is for the T-Mobile G2X (they're the same phone and both companies use the same radio frequencies). But maybe there's something written in these ROMs to tell the phone to look for the T-Mobile network? Which I obviously won't be able to find in Canada.
Can someone help me locate these settings, if they exist? Or can someone with a Wind phone maybe toss me the WIND stock firmware? Or let me know what ROM they're using without said issue?
Thanks guys!
Edit:: In low signal areas the phone drains like 15-20% per hour, in high signal areas the phone is still pulling like 8%-10% an hour and I'm not even using it! And the weird thing is it only shows 1% time without signal! Something is seriously wrong with this firmware.
Search for betterbatterystats on XDA, install it, enable battery monitoring in MIUI (if that's your daily rom), leave your phone alone for a few hours, then open BBS and look at the partial wakelocks under "since unplugged." There you'll see what's killing your battery.
Everyone experiences worse battery life when reception is bad, but you are still getting terrible drainage in good areas, which means there's something other than reception killing your battery.

I tried that before, and had a crapload of apps "frozen" with titanium backup.
I'm going to try this again, and I'll post a screenshot this time because I don't think I actually understood what betterbattery stats was trying to tell me last time.
If anyone can help me decode it later that would be great!
Just noticed that there's barely anything under partial wakelock that's noticeable.. RIJL Telephony is the highest with 1m 1s 15%.
But it's not increasing very much, only when I get a text message. However, I've dropped about 7% since my last message, and cell standby is increasing climbing up my battery usage from 33% to 42%. It went from 620uah to 657uah.
Edit:: I reset battery stats cause I was unsure if it was corrupted stats. I started at 17% 40 minutes later I'm at 12%. Phone was off 90% of the time. I made a 2.5 minute call and it used 41uah, while cell standby still dominated with 65uah.
However, I turned my phone on for 5 minutes, making total usage 45 minutes, but had the brightness set to max, and in that five minutes it only used 1uah.
Am I missing something here? At this point I don't know if my numbers are normal or not anymore... I'm going to try draining the battery, charging to full, wiping battery stats, and calibrating and see what happens but 65uah to 1uah is a huge difference, I would've thought display would use a bit more than that.
I noticed this morning that having the phone with airplane mode OFF, that my battery dropped 10% in 57 minutes, and after turning the airplane mode ON, the battery dropped 1% in the next hour and 30 minutes. I checked battery stats and nothing was waking up my phone. Anyone have any other suggestions?
I'm going to flash miui and leave it without any apps installed then try this experiment again.

I find these threads interesting because I am always looking for better battery life.
I am running EB 2.3.3
I uninstalled Set CPU and uninstalled Juice Defender. From my experience both hurt my battery life.
I never bothered to measure in airplane mode, because i use my phone to much.
My battery life improved dramatically during stand-by. 1% to 2% drop per hour with wifi on and a slightly bigger drop with wifi off.
I completely wiped the phone before installing EB and the used Titanium Backup to reinstall my apps without the data. I believe some of my previous battery life issues came from restoring data from certain apps.
I have the same phone/carrier. Do you leave 3G turned on? I feel it rapes my battery throughout the day. When I turned it off, it lasts pretty long.
Another problem I have though, is the drain when it is OFF. I went to bed with it at 90% juice and turned it off. I woke up 8 hours later, and it was at 65% when I turned it on. wtf. This only happens sometimes thou.. Other times it doesn't drop too much.

I experience the exact same issue. But for some reason my battery life is more or less the same with 3g off. So I feel like my phone is constantly searching for a different signal or something? I mean if airplane mode affects my battery life that drastically reducing consumption by like 9%/hour then there must be something up

Everyone who's been telling my phone is not sleeping is correct.
Only program is is that my phone's battery stats doesn't say which app is waking the phone? It lists Telephony as #1 with 1m 1s of awake time, and everything else is minuscule. There's gotta be something the phone isn't telling me :S Could it possibly be a hardware issue?
Or is there a better way I can narrow down this issue? I'm in the process of removing all apps.
Just curious, did you 'train' your battery?

Nope, but it's Li-Ion and my impression was these do not need to be trained.
I just emptied it to complete 0 yesterday, and charged it to complete 100% then calibrated it. Today though it was still horrible battery life until I completely wiped and flashed MIUI 1.9.23 then Trinity kernel brand new. I'm installing apps 1 by 1 to see which one caused me so much darn grief :S
All batteries are Li-ion nowadays, but I still feel after 'training' my battery for a week, they last substantially longer than new ones, fresh out the plastic.

Yes, battery drain is fixed. Also, I was on a completely different baseband for some reason, I was on the o2x baseband, fixed that JUST now, I think that was a part of the reason I was draining my battery like instantly. It was probably looking for a GSM signal!
Thank you for all your help
A simple *#*#4636#*#* can change that.

Quick battery drain & constant data being sent since 1.78 OTA

Hi,
I've got an HTC One S since a few weeks (got it with the 1.57 FW I think). It's a stock one, not from a carrier. No branding.
The battery life was great, 2 to 3 days with normal use.
But yesterday evening I proceeded to the OTA update and since then, trouble began
Battery life is much, much lower. After 12 hours standing on my desk in the office, I got 10% remaining!
Anytime I switch the screen ON, I see there is some data being sent (or received) because the "arrows" are full. If I check in system panel lite, there's always 1 or 2 kb/s of traffic.
Also, the phone is a bit warm, quite often.
Has anyone else noticed this? That's rather annoying :/
Could be faulty? I have the same phone with no carrier or branding and not had any problems at all.
Like faulty hardware? Seems unlikely to me since it worked well with 1.57. Also, sending data isn't hardware related
Here are some details.
In Mobile usage, just for today (less than 24h)
"Media" has used 13MB of background data
"Android OS" has used 5MB, also background
Android OS gives no more details. Media is told to include "Download manager" "DRM protected content storage" "Media storage" and "Downloads"
This sounds like a lot of background data :/
Try an app called Badass Battery monitor. It should tell you what's eating your battery.

I have to say, this phone, at least mines, seems to have a pretty bi polar battery. It's got a case of ADHD.
For example, just the other day, I had the phone fully charged when I awoke at 9am, after playing Temple Run, surfing the web, using GPS, streaming and listening to music, playing more Temple Run, fiddling around with the OS, checking emails, sending texts, talking on the phone a bit, downloading apps, with about 25-30% brightness, I ended up with 18% battery remaining after a good 11 hours of very heavy use. I was quite pleased, considering the inordinate amount of usage I had with the phone all day.
(BTW, I use Juice Defender, which has helped tons in reducing battery drainage for almost every phone I've owned in the past 3 months, including the One S)
Yesterday, I had the phone charged at 100% when I awoke at 9am, with a little bit of use, by 12am, I had 63% remaining, same brightness, but with much much less use then the day prior. By the time 3pm hit, I was at about 30%, and by 5pm, it was drained to 18%, mostly on standby. By my estimation, that's 8 hours of usage, same brightness levels as the day before, using Juice Defender, but with much much less fiddling around with pretty much everything on the device.
I went ahead and disabled Juice Defender today to see if it would make a difference, and the battery actually got a bit worse, so I went ahead and re-enabled it and it immediately improved.
So I'm a bit perplexed, I haven't gotten any official updates, still running on the original stock build, but ultimately, I guess this is what is too be expected with an early build. Hopefully future updates WILL fix these issues and not hinder them more. Granted it's still much better then my HTC Amaze and Galaxy Nexus, which drained 4% the moment I took them off charger.
Thanks for your input, I'll check again today how the phone goes.
I played with all the settings and menus yesterday, and found something strange. In the "downloads" app, there was a "system update" download. That's quite normal since I downloaded and applied the OTA the day before. But it was referred as "ongoing", like it was still downloading a part of the OTA zip file AFTER I applied it (and rebooted a couple of times)
In phone settings, about, updates, it was also written "ongoing"
Now this is over (I don't know why and how) and the network usage seems back to normal. I'll try today to see how the battery drain is
Anyway, it's s strange the phone was still downloading the update zip file after having applied it. AND that it was downloading it on the 3G at a very lowered bitrate (like background) while I downloaded it on the wifi the day before
Anyway...
The battery life of my One S seems to have declined as well since the update. Before the update my battery lasted 2 days easily with moderate usage. Now I have 20-30% left at the end of the day from a full charge since 9am. This is with very light usage (mostly on standby from 9 to 5).
I did turn on best wifi performance recently so I just to turned that off to see if it helps but I really doubt that.
Hello guys, I have same problem, but my phone wasting energy on "phone radio" process, just look at screens below. I tried using stock Rom with last update, trickdroid, and now it happend on leedroid v.2 . Btw I changed 4 micro sim cards with several providers, but no result. I really need help with this issue, because my battery draining very very
fast...
Thank you

I had a similar problem a few days ago, using Lee´s ROM.
I noticed that the drain had something to do with autosync. As soon as I turned off autosync (leaving mobile internet on) drainage went back to normal.
I still don´t know what caused this since I only had the google account, weather and dropbox installed.
Anyway, after doing a fresh install, the problems seem to have gone.
Of course I can´t be completely certain of it until some more days of testing/usage.
I also noticed quite a few problems since the latest OTA update.
Not only does the battery drain fast, the phone also feels extremely hot when browsing on 3G.
The phone does cool down pretty quickly when turning off 3G but it feels like I burned my hands
Here are a few screenshots.

I also experienced weird things when connected to EDGE (2.75G).
3G (HSPA) coverage on BASE (KPN) sucks in Belgium
Look at the video below for more details.
Has anyone else experienced this yet?

I also contacted HTC about this issue and they recommended a hard reset.
Unfortunately this doesn't help at all, I still get these weird glitches
mattionline, can you get a logcat when the phone's doing this weird stuff? It looks like the Home button is being pressed repeatedly and if logcat confirms it then it's probably a hardware problem.

Do you need root to make a logcat ? My phone is not rooted and I'm not planning to do it. How can this be a hardware problem ? I never had this problem before. I'm sure that it's a software bug.

I just fixed someone else phone that had the exact same symptoms. In the end I narrowed down the problem to one of his weather apps.
He had a live wallpaper that reflected the current weather, weather on his lock screen and a beautiful widgets weather thing. I never did figure out exactly which one it was I just turned off all there and told him he was crazy.
I don't know if it's something "weather" related for you but it maybe it will help.

you don't need root, just enable usb debugging in development options and connect the phone to your pc. You need to have the android sdk installed.
Sup guys , some of you don't seem to realize that there are many reasons why your battery drains, what you might think is, "quickly". A few tips to keep minimal battery out put...1 keep brightness down, the screen itself sucks juice probably the most. 2 check your apps, some apps send and receive data and/or are kept running in the background. You might have to enable/disable setting on shove apps. 3 widgets, widgets like battery meters, CPU meters, things like this constantly refresh to keep real time info. That also eats up alot of juice . 4 Turn off WiFi or any other thing like that when your not using it. WiFi continually sucks nice. Lastly, invest in some app that will help you close apps. Basically, tweek everything you might think that the os can run without. The less your CPU has to do, the more juce you save.

This made me lol hard.
Best advice ever.
But yeah, on the 1.0 version of Leedroid I had quite some drain, too.
When I turned off autosync it went back to normale. I only had my google account, dropbox (with syncing off) and the weather thingy set up and never figured out which one was resposible.
After installing Lee´s 2.0 ROM everything is fine.
I suppose there really is something wrong with the autosync and maybe with the weather stuff in particular.
My problem didn't go away with stopping auto sync, even without it, I had a constant data flow
Anyway, I rebooted the phone twice and the issue was gone.
It happened again a few days later, after the phone did shut down because of low battery. I put it on charger and turned it on, then, I noticed the 3G arrows were always on. After I unplugged it from the charger the battery went down in 10 hours. After a reboot, problem gone...
Since then, nothing...
And please note than when the problem is here, it's media and android os using a lot of data
I have been having one S problems too - I am on my second phone after the first one became reliably unresponsive every time I turned on mobile data. More relevant to this discussion, my battery died shockingly last night. Normally it drains at a few percent an hour when I am not using it (i.e. when asleep!) but I woke this morning to find it totally dead - that is 30% plus gone in 5 hours without it being in use.

Battery Crap after Update?

I got the update the day it came out, and ever since then my battery seems much worse. The next day it was at 20% at 6PM, (usually by then I have around 50%) I have not rooted my phone or anything. Stock just installed apps, changed text, background, stuff like that.
I am also one of those conservative people that has bluetooth, gps, wi-fi, even mobile data off when im not using it, so I am so confused on why this is happening.
Anyone else experiencing this? Just want to know if I'm the only one or if other people are too.
Yes, although minor but still noticeable.
If you install something like better battery stats you will be able to see whats keeping the device from deep sleep and eating away at your battery.
Sorry you're having this issue... An unatrractive but sometimes succesful option would be to factory reset your phone... Sometimes an update can go caddywompus :crying:
Once you're good at setting your phone back up you can root and start flashing difference ROMs... then things get really fun :laugh:
I've experienced this too. My batter went from about 15 hours on average to 4.
I have the habit of charging at night. When its done, I unplug and go to bed. Wake up in the morning, battery life is around 93%. After the update, battery life is at 35% upon waking up. Actively used the phone the weekend and have been charging it several times a day. I'm going to call Verizon and complain. I know it won't fix my phone, but hopefully if they get enough negative feedback it will help them fix the issue.
I've noticed that since the update "SD Card" has began showing up in the battery use screen. It routinely is using between 15-20% of the battery. Anyone else who's battery life dropped after the update seeing this same thing?

Battery life is plunging from 80% to zero

Hey all,
About three weeks ago I had a strange problem. I noticed that in two straight charge cycles, my battery life plummeted from about 80% to zero in just a few hours. I'm not sure what the issue was. I hadn't changed settings, installed new apps, etc. My first screenshot shows an example of what happened. 4G and data were off during the entire time.
Since then, things have been okay. I typically get 3 days standby with 4G on and light use, or 4 days with 4G off. That's mostly standby with maybe an hour or so of talking and minimal use.
After those strange battery plummets, I installed and used GSam Battery Monitor to get more details about what processes were running on my phone in case I noticed the sharp drop happening again. Everything had been fine for over two weeks, with me getting expected battery life before this issue and not experiencing any odd, sudden drops (maybe 5 or 6 charge cycles). This lends me to conclude that my battery's charge capacity is okay, and calibration also shouldn't be an issue.
However, the problem arose once again a couple days ago. Went from 75% to nothing in just a few hours. 4G was off during that time. The third and fourth screenshots show the same issue. Charged my phone, and this morning the same thing happened yet again. At about 90% the plummet began, and within an hour or so I was at 75%. At this point I took screenshots of Android's battery status, and I also did the same for GSam to show what apps and processes were running. The phone's temperature seemed fine.
The GSam screenshots taken when the phone was at 75% and dropping are in the next post, since I'm limited to four images in this one. I have no idea what's causing this massive, sudden battery drain. The only thing I can think of is that I've done Verizon's OTA updates, but otherwise pretty much all my settings, apps, and usage are the same. Plus, for two weeks I had normal battery behavior, so I'm completely baffled.
I also know that cell standby is incorrectly reported in the GS3 battery screen, and I'm getting a good signal where I live so that shouldn't be a problem. I forgot to get screen time for the first case (first two images), but it shouldn't be more than 10-15 min there since most of the charge was lost due to the freak plummet.
If anyone may have an idea of what's going on, or if there are some tools/tests I may use to figure this out, I'd really appreciate it. I turned off my phone after taking the screenshots at 75%, so if I need to turn it on and check something for you I can probably do that. Thanks a lot.
FYI, here are GSam screenshots from when the battery was in the process of plummeting this morning.
i think you built in battery status settings are off. i barely get 12 hrs with medium use, so what i think it happens is that the battery monitor is not showing the proper discharge, and then all of a sudden it catches up to the discharge rate.
are you on stock rom, rooted, unlocked bootloader?

I am stock rom. No rooting, no unlocking.
These plunges are definitely an anomaly. Truly, with me barely using the phone and turning off mobile data, I get a few days of standby. I've had the phone since July, and the aberration in battery behavior has been the steep plunges I've shown.
In between these instance of steep plunges, I've had normal use. I really don't think it's an issue of calibration. Please believe me when I say that my normal, light use during the past four months gets me anywhere from 3-5 days with me barely using the phone. When I say barely using it, I mean not even touching it for an entire day if nobody calls me. But now, a sudden plunge in battery life is happening at 80% with no apparent reason.
I think it might be some kind of software or hardware glitch, but it's impossible for this to be normal given the battery life I typically get. Just looking at that steep drop, it's crazy and just happens out of nowhere.
But please trust me when I say that these sudden plunges that have happened a total of 4 or 5 times, causing the battery to drain completely in a few hours when I'm not touching it, are quite a drastic aberration from the normal standby life I get. Something is definitely wrong here, I just don't know what.
And one more thing to add is that after this sudden plunge and rapid drain, charging the battery still takes the normal time it does when I'm not having this issue. That is, about 2.5-3 hours to reach a full charge (and I charge with the phone 'off'). The battery is being completely drained. But this happened twice, then didn't happen for maybe 5-6 charge cycles, then happened again twice.
Before the first instance, I remember an OTA Verizon update around 10/5. My phone was okay for 2-3 charge cycles after that. Then two rapid drains. Then 5-6 normal cycles. Then two more rapid drains. There was a second Verizon OTA update somewhere in there but I can't remember.
and you said it only started once you did the OTA update from verizon right? well you could either try to go back to the stock verizon rom pre-update and see what happens there, or contact verizon and let them know what happens with the new OTA update. they could replace your phone, or it could be a bug of the new OTA update. i am on stock rom and rooted and deleted the apk that kept on trying to push the update. just unlocked by bootloader and so far my battery life has improved compared to previous locked bootloader.
i would take it to a verizon store and show them. They might give you a new battery.
I may have to do that. I'm just not really sure what the issue is.
- The battery can still hold a full charge.
- Based on running services, nothing is causing high CPU usage.
- The sudden plummet almost seems kind of random.
- Since there have been normal charge cycles, it's not an issue of calibration.
I'm not sure if this is a hardware issue or software issue. I'm trying to wrap my brain around what could cause the battery to drain so suddenly and sharply. Could the charge somehow be "leaking"? But in that case I'd expect it to happen all the time. If there's an underlying software issue, is there any other tool I might be able to use to figure it out?

Not from what I can tell. Note that the first couple plummet drains were overnight.
But today I caught it before noon. The phone wasn't hot, and the GSam screenshots show no CPU stress.
Maybe you can do a factory reset and se if that helps. They will probably do one if you bring it to verizon anyways. It sure sound like a hardware problem. You'd think if the processors are working that hard that the phone would get hot, I know mine gets pretty hot sometimes under heavy use.

Thing is, all indications show the CPU isn't working hard, and the phone wasn't hot.
I'm stumped.
This is a noobish question, but I presume the only way to go back to stock is to factory reset? One thing I might wait for is the Jelly Bean update, presuming this random drain holds off until then.
But yea, I dread going into VZW because they're just going to try to pass this off onto me doing something wrong, or me not knowing how to calibrate the battery, etc. The information I've provided in my OP and in the screenshots would fly over their heads. Maybe I can just do an online chat and tell VZ to send me another battery?
The only other thing I can think of is that sometime before these plummets happened, I went online to MyVerizon and turned off the Backup Assistant for movies/music/etc. so I wouldn't get all those notifications. I don't think this could be the issue, since the plummet happens when data is off. Plus, GSam would show that Backup Assistant is hogging the CPU or forcing a signal.
I doubt swapping batteries will fix it, though. I'm thinking my internal hardware might have a serious problem.

Before the update, was everything normal?
Is the update with the HE base/baseband?
It probably isn't a hardware problem, just a bad base.
I've noticed after updating my GS3 to the HE base and the battery life was just horrid.
It's said that the new HE baseband uses up more battery also

Sorry, I don't know what you mean by "HE" base/baseband.
But yea, this problem didn't come up until after an OTA update.
Check your baseband version under Settings -> About and paste it here
Sent from my rooted Verizon Samsung Galaxy SIII
It's I535VRLHE
Kernel version: 3.0.8-1092717
Build number IMM76D.I535VRALHE
I turned on the phone and within 10 min or so the battery life went down by 2-3% without me doing anything. As a test I've put it into Airplane mode, and it's decreased by about 2% in 45 min.
Now I'm wondering if I have a faulty antenna or something.
Yup ive had it drain 90% overnight many times for no reason. Called verizon and my new battery should be here today.
1+ day on battery and only 11 minutes of screen time?!?

HE is the baseband version and the build number. For example I have: Android Version: 4.0.4
Baseband: I535VRLG7
Build: IM76D.I535VRALG7
which is the version before the update.
Like everybody else said, call Verizon or go to a store and let them know about the battery issues and they should send you a new one. Or even call Samsung and tell them you bought an S3 through Verizon and you are having battery hardware issues.

Well, no calls made or received during that time. No data being used.
So, wasn't really using the phone during that time...

Very High Android OS battery usage

I recently received an Nvidia Shield and updated it right away to 4.4.2.
Today I noticed that overnight the Android OS was taking up a large portion of the battery life. The Shield's Android OS used 70% of the battery while my Nexus 4 usually only uses 12% or so.
I'm not sure if this is because it's a new install or going to be a persistent problem.
Has anyone found out why this is or have a solution to fix it?
I don't want to disable multitasking. I'm probably also not going to root the device anytime soon just in case this is a real problem and I need to RMA it. I have disabled Wi-Fi when the device sleeps.
Actually, now that I'm looking at the screenshots again, it seems the battery stats aren't reporting the other apps I was using. Maybe it all got combined into Android OS somehow? I checked my Shield again and the games and apps I was using are shown and the % of Android OS seems to be going down.
I hope this was a fluke, but it'll be a few more days before I know for sure.
It seems it might have just been a weird glitch in the way the battery stats was shown.
Today I checked my Shield and it only used 3% battery life overnight with Android OS only using 9%. All the other apps also stayed visible on the list of apps.
Last night I turned on "Keep Wi-Fi on during sleep" again since it's actually pretty annoying when I'm trying to download something on the Shield and it gets cancelled when it goes to sleep.
I had 30% battery life when I went to bed and the Android OS battery usage was a low 12%.
I woke up with the Shield having 30% battery life still, but the Android OS battery usage shot up from 12% to 45%.
I went out for 30min and came back and the Shield had 32% battery life.
I used it for a couple of minutes and battery life dropped to 25%.
I have no idea what the heck is going on with the battery stats. I'm probably going to see what happens tonight and if the Android OS starts to get really high again I'll then turn off "Keep Wi-Fi on during sleep" for a few nights to see if that's really what's causing it.

Using the stock wallpaper. I think it's just an image.
Force GPU rendering is off. All the Dev options are default.
I'm interested to know if this ever gets resolved. I'm experiencing the same thing, just a tad more extreme. Android OS taking 95% battery. Been on the wallcharger more than a day, i wake it up and its at 45% charge. Stock, non-rooted, no Dev options enabled. I have a sneaking suspicion its related to Google Play services, but have no way of knowing.

So after doing a factory reset and getting the same results I finally decided to just unlock my bootloader and root the Shield. I did contact my 3rd party insurance company first to make sure they would still cover any hardware faults if I did that.
Anyway, unlocking the bootloader meant a factory reset too. Well instead of Android OS taking up the majority % of the battery life it became Wi-Fi that was doing it.
I thought it might be the battery so I ran it down to 0% then while charging it back up I just said, "Screw it," and started fresh using the Recovery OS Image from the Nvidia site.
SO FAR, it seems to be much more normal in terms of the battery stats.
What's weird is Android OS and Android System have swapped positions compared to the way my Nexus 4 is.
It'll probably be another day or two when I use the Shield some more before I can make sure it's all better.
Update:
Nevermind.
Overnight Wi-Fi and Android OS shot to the top of the battery usage.

Not more than a week and a half ago, I did a factory reset on my Shield, for reasons unrelated. I was running into problems where the thing would randomly reboot in the middle of playing games. I attributed it to issues related to moving games to SD.
After the reset, and re-install of everything it has been running rock solid, it's only past few days this battery drain started being an issue. Last night I went through and unchecked 'show notifications' for any and all downloaded games, not sure if that makes a difference really. The thing sat on the charger an entire night, and in the morning it was still only at 52% charge, Android OS still being the top offender.
I've turned location OFF, and set WIFI to off during sleep. Going to see how the battery looks after a few more hours. If I was more adventurous I'd root, and install a wakelock detector, but I'm just not that motivated. I'm hoping if I ignore it the problem will work itself out eventually. Not sure what to think, none of my other Android tablets or phone are experiencing this phenomenon.

Setting Wi-Fi to turn off during sleep does sort of help keep Wi-Fi battery usage down, but I just find it so inconvenient.
I just rooted and have BetterBatteryStats installed. The Kernel Wakelock category doesn't show anything for some reason and nothing unusual about the Partial Wakelocks.
The only unexplained thing is a Process called migration/0 that has been on for 15h 15m 6s even though the device only shows an uptime of 13h 1m 26s. A quick Google search says, "The migration kernel process distributes workload across CPU cores. You should have one migration process per processor core." so I guess it's normal?
Also, while typing this, my Android OS battery usage shot up to 80% and my Wi-Fi is now at 10% which is still higher than the Screen on usage of 7%.
I also just used ROM Toolbox Pro to freeze all the Nvidia system apps, like NVStats and TegraZone, to see if that will help at all.
I have this feeling that it is Android 4.4.2 that is causing the problems and I hope Nvidia at the very least updates to 4.4.4.
I've been reading some more articles and there are some that point to the external SD card being the culprit of the battery drain.
It seems to be that Media Scanner is trying to constantly scan the external SD card.
I'm not 100% sure if it is the cause because on my side I don't have the Mediaserver using any battery.
The next time I fully charge my Shield I might try removing the MicroSD card to see if that is causing it.

I'm not sure removing the SD card changed anything.
I did notice a process in BetterBatteryStats called migration/0 that is very high usage and I have no idea what it is for or how to stop it.
Okay, so I think I've found the cause of the high Android OS battery usage.
First my solution:
In the Settings -> Accounts -> Google -> (your account)
Leave Sync enabled, but ONLY check "App Data", "Chrome", and "Google Photos Auto Backup". Leave everything else un-checked.
Set Wi-Fi to turn off when the Shield goes to Sleep.
*I haven't bothered to test individual sync option, but those are just the 3 I left checked. You can try it yourself to see which one is the real culprit. My best guess is it is Calendar syncing that is causing the problems.
*Do not just disable Sync. I found that did not help at all. I don't know why.
*I don't know if it's my router or the Shield, but Wi-Fi also uses way too much battery when asleep. I can see that it is going into deep sleep too. Setting Wi-Fi to turn off when the Shield goes to sleep drastically lowers the Wi-Fi battery usage. Fun fact: The Wi-Fi stays on for 20 minutes after you turn off the screen before turning itself off.
After un-checking a bunch of the syncing options my Android OS battery usage went down to 20% for a 20 hour period compared to the 70% or so it was using the day before I did it.
The "migration/0" process no longer shows up at the very top in BetterBatteryStats. If it is showing up, it is <10sec of usage.
After 20 hours, with about 35min of 3D gaming and 40min screen on time, the Android OS battery usage was using 20% with 30m30s of CPU Total. I also spent about 10min transferring files using AirDroid then moving them to the SD card.
The battery life dropped from 100% -> 84% in those 20 hours. I think I would have had battery life closer to the Anandtech review if I was just doing 1 thing consecutively and not gaming then using the Wi-Fi to move files. I might try that one day, but most likely not.
I hope this helps for everyone having the same problem as me.

Thanks for this pointer.
I was also facing significant CPU consumption by the real time kernel process migration/0 on my Googy-Max-1.7.9 kernel.
I turned off the calendar sync and this seems to have fixed the issue. Now I am only syncing App Data, Contacts, Gmail and the others [browser, Calendar, Chrome, Chrome Beta and People details] are off.
