"OS System" and "Android OS" CPU Usage - OnePlus 3T Questions & Answers

I've been experiencing massive battery drain from CPU Usage by "OS System" and "Android OS" in multiple ROMs, including Stock. It uses CPU for a long time (6+ hours) to a point that my phone is pretty much awake all night if i leave it unused. I cannot last 1 day on standby without even using it. This is getting incredibly f**king annoying. I've tried flashing custom ROMs, custom Kernels, going to privacy guard and revoking permission to keep device awake, removing app permissions and more. This just started out of the blue and is intolerable now. Anyone has a clue about how to stop this apart from just selling the phone?

Been running into the same issue as well. Pretty much tried all of what you've stated along with disabling most of the google syncing apps to no avail. I ended up turning off doze/aggressive doze on OOS 7.1.1, and use greenify (aggressive doze+automated hibernation) on every single apps except for whatsapp/textra (or any other apps I don't mind wakelocks on) and I can get through a night of 8 hrs on wifi with about 2-3% drain. This include greenifying system apps like chrome or playstore. This also helps with the standby time tremendously during daytime when phone is on mobile data. One thing I've read that helped quite a few people is also disabling google backup which seems to be one of the major culprit along with facebook/snapchat. Saying all that, Android OS and OS system still constantly top the lists of battery drain for me, but my standby time has been decent with greenify.

Probably some app updates , I use to have that problem , no more with 7.1.1

Are you sure this is not just the new background optimization doing its work slowly in the background, this feature was introduced in 7.1.1 from what I've heard. As long as you don't flash a new ROM every day, the second day after you should have normal usage when the optimization is done.

I had that exact same problem as well. I forget what I did to solve it though. It appeared for me right after updating to Nougat. Try flashing a custom ROM (since you have the 3T, try using this rom. It's the one I use and I get 7+ hours of SOT with it), preferably with no gapps at all, and no root and leave it like that for a day or two. I'd say after a full 24 hours you'd be able to judge whether the phone is still having battery issues or not. Use the phone as you normally do as well. Don't deviate from your normal usage. And make sure you get at least one full 100% charge in as well during that time period.

New battery and phone still drains like crazy?!?

I have reached a point of frustration that I can hardly bear anymore.
If I remember correctly, it all started last year around Halloween when I first tried out NewMaclaw's CM11 port. I was dissatisfied with the unusually high battery drain and soon returned to stock where everything went back to normal for the following months. Due to my banking app requiring at least Android 4.3, I started experimenting with the available ROMs again in April. Since then my battery life has never returned to an acceptable state again. It doesn't matter what ROM I use, I would never make it through the day.
I always blamed it on the custom ROMs because after returning to stock for the first time, the battery life was decent again. Due to the suspicious behavior of my battery lately, like dropping or gaining several percent at once upon connecting or disconnecting the charger, I went back to stock for the second time the other day, to determine once and for all whether there was something faulty about the battery. And I thought I would have confirmed just that when the battery drained just as fast on stock. So naturally I ordered a brand new battery (manufacturing date May 2015), and hoped for satisfaction at last.
But this phone is just merciless and continues to punish me for reasons that completely elude me. The first day on stock after a full charge, the battery lasted for a mere 23 hours on stand by in AIRPLANE MODE!!! WiFi was enabled, but only for being able to receive text messages on surespot. No other push services were installed. After the second full charge, I flashed the latest CM11 and instantly noticed that the crazy draining hadn't changed. As a final act of despair, I did an advanced wipe to delete everything on the phone except the external SD card. Of course the effort was meaningless, I was down to 16% after only 11 hours with a screen on time of 2 1/2 hours. All I did was browsing with Firefox. No video or audio, just common websites. Today I did the same thing after yet another recharge, and lost 20% battery after 45 minutes. I always set the display brightness to minimum by the way.
So if it's not a faulty battery, then what the heck is it that prevents the battery from operating normally?!? I really tried everything in the process - flashing several different ROMs, going back to Stock, disabling the location and wake up features of Google Play Services, buying a new battery. What else can cause such ridiculous battery drain, and why did it not occur before I started flashing?
Hello, have you tried to debug which apps and kernel wakelocks eats most battery? Try to install betterbatterystats: http://forum.xda-developers.com/showthread.php?t=1179809. That might give you some hint what eats your battery.
Thanks for replying. I don't think it is any particular app since the drain occurs even while on TWRP and right after flashing before having installed any apps. It is also the same whether I browse the web with Firefox mobile or send and receive messages with surespot which are the apps that I primarily use most of the time. I'll give your battery stats a try anyway.

Very disappointed in OP3t battery life. Not sure what to do.

I'm coming from a OnePlus One. Unfortunately, I can't find reliable BLP571 replacement batteries in the U.S., so I purchased a new OP3t.
On the OPO, I have been running custom MM and N-based ROMs. When the OPO (currently running Nougat 7.1.1 on TugaPower 2.1) is sitting around doing nothing, I typically see my idle battery current drain at around 9 uA to 14 uA and Wakelocks around 10%. Of course, when I turn the screen on, these jump up.
On the OP3t, I have tried running both OOS 3.5.4 and the new TugaPower 4.0 (which is based on Nougat 7.1.1). When the OP3t is supposedly doing nothing, I saw an idle current of around 85 mA on OOS 3.5.4, and around 35 mA on TugaPower. I didn't check the Wakelocks on OOS 3.5.4, but the Wakelocks on TugaPower are around 93% awake time (!!!!).
When I wake up in the morning, the OP3t is down to around 75% battery. For reference, my OPO used to be around 98% overnight when the battery was new. Even now, my ancient OPO with a nearly useless battery is around 85% for the same overnight time period.
What can I do?
3.5.4 actually has drain issues, try 3.5.3
Even after the annoying wake-locks and the random battery drain that just happens because why not... I still manage to get 5-6 hours of SOT, I have managed to push it till around 9 hours if I keep the Bluetooth and data off; with Greenify and using the aggressive doze it has helped but I don't get any notifications until I turn my screen back on.. Which is fine with me, as I get texts and calls. It's much better than the nexus 6 and the galaxy s4 which would struggle to even get 4 hours of on screen time. There are plenty of people raising issues about battery life on the OnePlus3T even though its probably much than your last device. XDA also has plenty of threads already created talking about the same subject.
Edit - I'm on the latest nougat update 4.0.1
the 3T or OOS doesnt have any drain or bad battery issues.
the problem is user/user-app based.
sort out the app which is causing the problem.
I just made a post to a similar thread. It seems the battery issue is hit or miss. At any rate, please check my post here: https://forum.xda-developers.com/showpost.php?p=70581453&postcount=9
Let me know if this helps you out. Look forward to feedback.
Greenify + ForceDoze = problem solved. I see 1% drained per hour at the very worst.

You stole my thunder.
Just kidding, but you're absolutely correct. I'm waiting to get my OP3T and then I will write a tutorial for users to help them out with the battery. Those 2 apps will be in my tut along with a few others that are helpful!
Weird, usually my phone, while idle of course, drains by 1% every 2 and a half to 3 hours. During use while im not playing games or anything im using pixel filter. Most time ive gotten is 9 hours 32 mins screen time. Im on 4.0.1 not rooted. Just uninstall apps u dont really need like amazon, youtube, facebook, tumblr and so on and use Firefox web browser. Firefox has background play for YouTube or any other audio source so you can stream music on Spotify soundcloud or whatever you want. I basically rely on Firefox for all internet things as if my phone were a PC. Saves time and battery because with 6gb ram my browser never slows down or reloads. Firefox is also really nice in the background consuming only 10mah every hour when not active or streaming audio. Cutting down ur app count will allow your device to doze longer, fetch less data and it certainly drains far less. Also if you're into this sort of thing, boot times are much quicker too.
Edit: sorry for the unedited massive paragraph here.
Another Edit: Make sure in case you want to use battery saver mode while streaming music to toggle Firefox to have unrestricted data usage in the data saver menu.
Check the link in my signature. My drain wasn't quite as bad but might help you figure it out. Good luck!
Thanks, guys! Greenify + ForceDoze seems to be helping a LOT! I'll need to let it run a few days to see the the real-world numbers.
I am having a problem adding apps to the ForceDoze Whitelist, though. Is that a known issue?

I've found that the whitelist appears blank until you add or remove an app, then the whole list will appear.
For me at times something appears to kick in in the background causing the CPU to spike and the phone to heat up. I can't figure out what it is though. When this isn't happening the battery drain is virtually zero and the phone flatlines overnight ,when it kicks in,the battery loses about 10% an hour on idle. I think there might be faulty drivers or something in the ROM causing this?! It's not apps as it happens to me on a completely debloated ROM with no apps. This is on Lineage and OOS. I've never seen this before on the phones I've had.

OOS 4.01 - I am experiencing exactly what you describe at 12%/hr and I have done literally all of the suggestions here. I have greenify, force doze, turned off location, disabled swift, did a factory reset and installed only 1 or 2 apps- and still I can watch battery drain with:
4 hours off charger and down to 44% with:
Kernel (android OS) 42.5%
Android System 33.7%
Google Play services 2.4%
Blah...Blah... (much smaller %'s)
What the heck could be causing this kind of drain? It seems to flatline when not in use for a while...
thoughts? Love the phone., but it is not usable like this....
4.0.1....No battery saving apps..

Hello,
I usually use Greenify Paid Version + Amplify Paid Version but only in 6.X roms in 7.X Xposed isn´t released yet....
Do you recommend use Greenify + ForceDoze (I never heard about this app) even without Xposed?
Thanks in advance.
I am still struggling with battery performance on my new OP3t.
I am running TugaPower N10 (LineageOS 7.1.1) + Better Battery Stats + Battery Monitor Widget + ForceDoze + Greenify.
While my wakelocks seem to be pretty short now, my lowest average current drain is 35 mA. For reference, my old OnePlus One had a lowest average current drain of 7 mA, or about 5x more on the OP3t.
My battery meter reflects the higher drain.
I have the same apps installed, maybe even some less.
Looking for more assistance ...
I'm on 4.0.3 OOS and using Franco kernel, 2% drain during all night, 5 hours of screen on time and still 56% battery, check what is wrong with your apps, or move from Lineage to OOS, is simply better.
EDIT: I'm not using any app like ForceDoze or Greenify
I'm not dissapointed.

OnePlus 3T SOT only 4.5 ish hours

I have got my one plus 3t about 2 weeks ago. I have noticed that it's screen on time is never over 4.5 hours. I've read people saying their op3t SOT is over 6 hours.
Currently it's running oxygen OS 4.0.3 (Android 7.0)
I can't compare against the SOT in marshmallow because after I bought it I instantly upgraded to android 7.
I followed some steps suggested in several forums that should fix any battery drain issue such as wiping partition cache from recovery mode, clearing Google play service cache, turning on doze mode from DEV mode. It didn't get much better.
My usage pattern is mostly light to moderate. I use Facebook, fb messenger, aqua mail as default mail app, deezer for music. I am normally on my wifi most of the time. I turn on data for a small portion of the day. I turned of location service and Google location history. My screen brightness is set to about 20%.
Can you help me understand what's the underlying cause? It's not that I'm not happy with the battery performance. It lasts easily a whole day for me. But having more SOT would definitely be great.
Note: Unfortunately can't share my screenshot here as i'm new to this forum.

o.o you use Facebook and Facebook Messenger. To my knowledge they both encompass a whole lot of wakelocks that keep your device running after you put it to sleep. First thing would be to either greenify (if it will help) or delete both of those applications. I dont use em, but if you go to any battery saving thread on android most tell you to do something to keep those apps from running unless you want them to, instead of just, on, all the time doing meaningless things like holding the phone awake.
Without Facebook installed, only whatsapp and surfing, I am getting around 7,5 hours SOT. I'm on freedom os open beta, stock kernel.
on oos rooted with elemental x kernal, whatsapp snapchat and instagram only no facebook or anything like that, i am getting 6 hours screen on time with a bettery life 2.5-3 days 100% to 10%. Obviously i am not addicted to my phone the screen is on about 2 hours a day on average sometimes 3. I have no idea how much screen on time i could get in a single charge if i was a heavy user but i reckon it would be high based on the rest of this post.
Edit: For those on franco kernal i tried it and it was not even close to elemental ex i was get 1.5 days battery at best and that was with the battery profile enabled.

instead of using greenify, would it help if I use the Aggressive doze mode? It should put every background app (including Facebook and FB messenger) into hibernation). Shouldn't it?

Greenify makes a massive difference. I was using naptime that puts aggressive doze on as soon as the screen is switch off and i was still getting more drain that i wanted (about 3 percent in standby).
Now people will tell me greenify doesnt make a difference, answer me this then. How do i have a screenshot of an 8 hour period over night where i lost 0.1% per hour.

Standby in night seems use less power than in day. I think the reason is that you don't wake your phone at all at night.

Why does everyone find this so hard to believe. At night i would lose 0.6% per hour. With greenify i lose 0.1%. Greenify makes a difference, simple.

No, I believe you man. I use Greenify too. Just saying a fact that I observed. I thought you're comparing the day time drain with night time drain.

Battery drain after Android 9 update

My phone got the update to Android 9 a little over a week ago, and since then it has been losing battery like crazy. For example, last night I left it unplugged as a test, and it lost 30-40% of battery within 6 hours (while I was sleeping). Before the update, a fully charged battery was able to last for two days, now it doesn't even manage one. The phone is often noticeably warm.
I restricted all "consuming apps" some days ago, that did not make any difference. I also tried 3rd-party apps to analyze the battery consumption, but did not find any way to figure out what consumes all the battery in the background / while the screen is off.
Using Google I found other people with the same problem, but I did not find a solution. What can I do?
I had a same kind of problem but it started a few days after a manual update flash. I had been experimenting with some root stuff (mostly magisk though so they should go away by uninstalling the modules) but could also not figure out the reason for the drain.
I also tried to reflash only system and vendor partitions, but ended with a bootloop, so I had to flash the whole firmware again. No problems after that.
I would try a factory reset if I were you.
You can also try GSam battery monitor (if you already haven't) to figure out what's happening with your phone while the screen is off and it should be sleeping.
I upgrade the XPZ yesterday to 4.41 Pie. Charge the mobile after upgrade to 100%.
The current situation looks like:
18hour active, 30 Min Display, a few calls... Whatsall, newsletter, Mail..... are running in the Background, LTE, EDGE and WiFi are always on, BT has a connection to my watch...
88% are still in the Accu. (Save mobil datatransfer is aktiv; additional the option is enabled to reduce power consumption for apps in background)

Massive battery drain before and after wipe

Hi. Can someone help me with my problem?
Im facing massive battery drain even after wipe, im only getting around 3/4h SOT. In BBS, 2 alarms are weird Job.delay. And job.deadline. I have wiped my phone, installed last version of rom, after that i have restored my apps. Problem still exist. Next i have installed kirasakura kernel and then frozen every of my apps, and its still there. After night im losing around 10/20% of battery. Im attaching some screens from bbs. Thanks in advance for every help.
i'll try to help as much as i can. install servicely and look at running services. if you see something weird, stop that service.
also, i see you're using bluetooth. that thing drained my battery as bluetooth would stay turned on even when it says it's off. what you can do is turn it on and off and it should stop bluetooth service from running.
in servicely you can disable apps from running in the background. maybe some app is running full throttle even tho you thought you closed it.
another thing you can check is if xmode is running. once i had system turning on xmode on even tho i closed the app that used it.
as you're rooted, check with some kernel manager what cpu governor is turned on. maybe the system is stuck in performance mode.
lastly, you can check your battery capacity. maybe it needs calibration. that could also result in battery drain as it's not charged to the max.
also, android 10 is generaly badly optimised for our phone. it has some good features, but powerwise it's not that efficient.
if nothing works out, i'd suggest returning to latest android 9 and do battery calibration.
Thanks for answer. I have installed servicely but im not see anything suspicious. Xmode is off, governor ist in performance mode. About battery calibration, i dont need extra juice from my battery, i want to lose 1% over night, not 20%.. Probably around July/august everything was fine, my battery last for almost 3 days, now something eating it alive and i dont know what is it. Can i somehow check which app generate this "job" alarms? In BBS its "Android" only..
battery calibration isn't about extra juice, it's about system showing the right percentage. you could lose a lot of battery because it doesn't get charged to its max capacity.
there could also be a problem with the lastest update. when i was seeing a lot of battery drain, i had it because system constantly used location services. check in services if there are any location processes running. also it could be because of network. maybe your phone is constantly switching between 3g and 4g.
you can also check in the kernel manager what is your current battery draw in mAh. if its always over 300mAh, then you have a problem.
look for a wakelocks running in the background and disable and enable some to get them resetted.
Probably u have solved my problem. Even after turning off location, i still have some running services with location in name. I have blocked all of them in servicely and after night i lost 1% of battery. I will check now in later days. Thanks a lot

A reload generally solves nothing and wastes time. It's always best to find the root cause(s) and address them directly otherwise they tend to reoccur.
Viruses (never had to), boot loops (prey it works) and old loads are the only times I reload.

yeah i thought it could be that. it's also worth checking if you have "find my phone" turned on. it's somewhere in the settings. search for device admin apps. if you see any apps turned on as device administrators, turn that off. those could also drain battery
Yep, i have turned off "find my phone" now. Thanks once again. Now i have nearly 8h SoT again. I hope it will be all good now
i'd still do battery calibration if i were you. 8 hours of sot is not that much. i mean, it is if you're playing games all the time
After couple of days, problem is back. No new apps, 3 days was good, 0/1% drain in night, now its again about 15/20%. I will just sell this phone becouse i dont have any more patience...6000mah and my OP3 with half of that value can ez get about 5h sot. Aktually im getting about 3/4h sot and 3h calls. When i have bought this phone i have had about 10 h SOT and 5 h of calls in 3 days of usage. Never again gonna buy phone from asus. Thanks guys for every help
i wouldn't condemn the whole brand because of one phone model.
also try going back to android 9 and check how's the battery drain without any apps installed. then start installing your apps and monitoring if the drain will increase.
i'm currently on android 10 and there is some major problem with battery regulation. raw capacity goes below zero when the percentage is below 10 percent. no wonder the whole system starts stuttering when battery level is below 3%.
