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?
http://youtu.be/3g8FLpWDAYM
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.
I've been running TeamEOS on my Xoom for quite some time, and it's been great. However, recently the device's battery life has become incredibly poor. For example, today my Xoom has been unplugged for 8 hours 47 minutes, without being used at all, and the battery is at 61%.
Previously, the Battery usage settings view was showing the Wi-Fi in use all day, but today I turned Wi-Fi off and it is still the same. The 'GPS on' line shows one small section of blue (about 10 minutes) and the 'Awake' line shows a few times it has been awake, maybe half an hour in total.
I installed BetterBatteryStats and the longest Kernel Wakelock is PowerManagerService, for 2m 2s, the longest Partial Wakelock is ConnectivityService at 57s.
Under 'Other' it shows that the device was in Deep Sleep for 8h 39m.
Another odd thing is that when I first unplug the device, I get a kernel wakelock on cpcap_otg. If I don't do anything the battery drains even faster than it did today (it never goes into Deep Sleep), but if I plug in my USB card reader (without a card), and then unplug it again, that wakelock doesn't happen again, extending the battery life slightly.
I have a Wingray Xoom (MZ604), and I currently have TeamEOS nightly 114 installed. I have tried various nightlies, back as far as 90, and have also done a factory reset, to no avail. I haven't yet tried going back to Honeycomb, although maybe I should just to check, as it certainly used to work fine under TeamEOS 1.0.
Does anyone know anything else I can try to do to fix this?

Battery life seems to be so device specific that it's really difficult to diagnose, tho you seem to be looking in the right places. I'm on 114 as well and my battery life is fine...normal for my device, depending on use. It is said that you need to let a new rom install settle a bit, and I've been told to flash a new rom with a full charge...other than that, I don't know.
It could be some app you recently installed that wakes up your device wifi and consume battery. To diagnose more, get betterbatterystat app.

He said that is the app he is using. I'm sure, as you said, it is an app causing either wakelock or something syncing in background.
Are you syncing Facebook? I uninstalled the app a long time ago and battery life went up.
Tried wipe battery data in recovery? That may fix your battery issues.
kinda old thread, but if you are still facing battery problems, try this.
go to settings/wifi/advanced and choose never for "keep wifi on during sleep"
I had the exact same problem and it turned out that the device gets a wakeup call from the wifi router every now and then, which keeps it from entering deep sleep mode, resulting in horrible battery stats, running dry after about 1,5 days of just laying around.
Since I did the setting change, my xoom lasts for almost 1,5 weeks at light to medium use (mainly browsing and email) now

true, but don't forget that will also kill your apps from keeping their state up to date. email push won't work anymore. it's a matter of what you want, i personally rely on the phone for incoming mail and use the xoom for reading with disabled wifi during standby. it's the best of both worlds, instang notification and long battery.
oh, of course you´re right.
I didn´t thought that this could be an issue for other people.
Like you, I get my mails on phone and work on them on tablet.
Like you said,best of both worlds and feels so natural
But I still say, if you can sacrifice the "always-up-to-date" satus on your tab, just do it cause the battery uptime afterwards will be totaly awesome.
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.

I've been using the latest ota 44s rooted, but with no modifications. its probably the most stable yet. no issues apart from this. despite the battery being actually quite good, i get 6+ sot within 40+ hours. but i'm getting an issue where according to the battery monitor, it drops a few percentages in one go without me actually using the device. its still on deep sleep. no wakelocks or anything like that.
Could it be that the battery stats is not being monitored properly by the phone? where the phone is going down steadily and then it realises the battery is at a slower percentage than its already displaying?
or is it something else?
This has happened to me several times previously. though no reboots, and battery life is still good.
as you can see here it drops from 86% to 77% whilst the -mAh is at -9mAH
Use a app such as better battery stats and debug your apps. There's most likely a app causing the phone not to properly deep sleep

Re: Phone deep sleep battery drain
I have also come across the sudden battery drain issue this past week. My phone deep sleeps well and I can find no wakelocks. It appears to use excessive battery when idle. I have tried a fresh, blank install of CM11S 44S and that didn't resolve the issue. I have since moved to Cm11 nightlies and that slowed the battery drain but I am losing 12% battery per hr when idle and the phone is staying warm. I do not understand how this happened and why it just spontaneously began. A fresh install with no additional apps, and no problems entering deep sleep. shouldn't be doing this This phone was brilliant for battery life and I cannot work out how to resolve this.

I have also come across the sudden battery drain issue this past week. My phone deep sleeps well and I can find no wakelocks. It appears to use excessive battery when idle. I have tried a fresh, blank install of CM11S 44S and that didn't resolve the issue.

Have you checked what frequency your CPU is at while idle?

I have checked that and it appears to be sitting at the minimum 300MHz as far as I can tell. Since posting I have tried PA 4.6 for 24 hrs, no additional apps, and now I have moved to Liquid Smooth Lollipop nightly just to see how they compare. Even changing radios doesn't appear to have any impact on the power consumption.
When using GSam battery monitor on both the CM11 and PA (both behaved similarly) my phone was using anywhere from 500mA to 800mA (minimum screen brightness) for no apparent reason. I am unsure what usage this phone should be to be honest but I think that is high.
On Lillipop, the category 'Miscellaneous' is by far the greatest usage category and is seeing 2-3 times expected mAh drain compared to its computed usage, though I am unsure how that is worked out.
The most my phone will last now is 8hrs standby, in deep sleep. I am beginning to wonder if there is something wrong with the hardware of this device now. Perhaps the power regulator... Not sure what test to do next TBH
Thanks for your reply

The next thing I'd do would be a complete wipe and flashing the fastboot images. This still return the device to a completely stock state (including wiping the user data), leave it like that (don't install any apps) and test for a day or two.

Before flashing the CM11 Nightlies to see if they rectified the issue, I had downloaded and clean flashed the stock 44 image via fastboot but the issue remained. I shall re flash it though and post back...

Fresh install, data off and left to own devices for a few hours and it is deep sleeping like you would expect, but a neat linear drop in the battery of 10-12% per hour as before...
I saw the same type of behavior while running CM11 based ROM. At night, I would put device into sleep (no data/no wi-fi/no sync/etc.) - basically everything off. In the morning, it would still show 100% - but then quickly drain several percentage each minute for the first 10 or so minutes. It was like it was catching up to the correct %. I have used wakelock and BBS and nothing sticks out. I also set Google Play services to stop wake (which did help battery life a lot).
I took my Shield Tablet (stock 5.0/rooted) off the charger at around 8 am today starting at 100% (charged while completely off), and at 11am I noticed it was at 49%. I'd only done some mild gaming (Terra Battle), and Comixology reading, so it struck me as a little low, but what confused me more was the battery stats page. Screen shows at 130%, System at 10% and everything else in single digits.
Anyone know what's going on here and how to fix it? I've rebooted and will be watching out for whether it happens again, but would be happy about feedback from anyone who's experienced a similar issue. Thanks in Advance!
Since you are rooted you should use an app like Better Battery Stats to log what is going on.
This way you can identify which app is causing the drain and take measures to prevent it.
Known cause in quite some cases is Facebook after applying the ota to 5.0.
Solution is to remove the facebook app, do a factory reset and install the app fresh from playstore.
Thanks for the reply. I don't and never had the Facebook app installed (shocking, I know ) so that can't be the issue.
I've installed Better Battery Stats so I'll see if I can figure anything out through it...
My guess is that the screen has used 130% of the batteries capacity. If you look at the bottom of the graph it says stats since last full charge. I gave my niece my old first gen nexus 7 with lollipop and a few days later looked at the battery stats. Her screen was listed as 160%. It hadn't been fully charged since I gave it to her. The screen brightness was maxed out and she tends to leave it on the ground with a video playing. The screen obviously uses a lot of power so its not hard to imagine it was over 1.5 times the batteries capacity.
