battery draining fast-screenshot attached

so i'm trying to figure out why my battery is draining so rapidly. I'm charging once and rarely twice during the day at this point. I'm running the latest and greatest from leedroid if that matters. attached a screenshoot for reference.
Anything else you need to help me with this just ask and I will answer. Thanks!

There doesn't look anything too bad from that screenshot. Have you got gsam battery monitor ? Try that and see what ' app use ' shows. I had a problem for a day or two on the same rom ( nothing rom related ) and no amount of reboots solved it. For some reason the kernel was keeping the phone awake 100% . Sometimes it's an app or a download or some media on the device, if it's a recent problem check everything that's been down or uploaded and any new media or app on the device. A wipe would likely fix it but try and narrow it down first. I think my issue was a play music download but can't be sure as I cleared cache, dalvic cache and data for several apps.
It's now back to usual ( 5 hrs SOT )

android system and kernel combined have 40%, they are the top 2 consumers and have the most wake locks.

That's slightly high but not drastic. There's a ton of factors for battery drain, what's the 'held awake' time versus the sleep and how much SOT do you get ?.
Another way to narrow things down is to leave it with data off for several hours to see if the drain stops.
There's dozens of options on Leedroid which could change battery life , including the kernel options in aroma . Ambient display can drain battery as can some of the ways to turn on the device.
You could try to wipe all the caches, clear data for Google apps and maybe dirty flash the ROM and see if things improve.
Maybe also try the battery calibration as detailed in other threads. There's a possibility the battery may be degrading of course, check the thread for that and see what your capacity is now.

Do you have the Facebook app installed. For some reason, I seem to notice battery drain more with some Facebook updates. I don't know what it is but my phone will easily last a day, Facebook update arrives and phone needs charging twice a day. Another Facebook update arrives and its ok again.

I think something is really wrong with the 10 lately. My battery goes down like crazy as well, I first thought it was my device and performed a factory reset, but still the same issue. Now I see that there are a lot of people mentioning the same thing the last few days.. Can't be a coincidence that my battery went bad along with others' at the same time..

i have ambient display off, i also selected one of the battery saving kernels. i had about 10 thousand wakelocks coming from powermanangerservice.wakelock this morning. the sucky part is i got frustrated and just uninstalled better battery stats after seeing that. i know that wakelock means there are tons of partial wakelocks.... it's just becoming a pain. hate my phone right now.
()after i left work) i just installed better battery stats again and i'm gonna let it sit.

Mine was bad again yesterday but back to good today. Only change was a Google play update ( pushed by google, I assume play services as it updates itself not through the store ). Maybe see if there is a more recent play services that helps you.
I thought power management services was the turning on of the screen/device but may be wrong , do you have wake gestures enabled ?

no wake gestures, honestly i disable all the bells and whistles b/c battery on most phones. and here's what i got after a days use, SOT 2:50. The important thing to note my phone rarely get's used. text throughtout the day and video on the train ride home. music. i think that's pretty basic. what're you guys thoughts?
below are screenshots from Better Battery Stats of kernel and partial wakelock.

Anyone else getting severe battery drain from "Android OS" on 4.7.6 ?

My 5T is constantly losing battery due to "Android OS". I think it started when I updated to OOS 4.7.6 because it seems to have started within the last week or so, but I'm not sure.
I am currently sitting at 52% with 13 minutes of screen on time. 13 minutes.
https://imgur.com/a/Xfj7y
I know it looks like it's because of poor mobile connection, but that's how it's always been with T-Mobile in my area. Like I said before it hasn't always done this, so it isn't that.
I am rooted with TWRP and Magisk. Nothing too fancy just a couple of Xposed modules that I installed the same day I got the phone. So I know it's not any of those either.
I have already tried using Greenify to kill everything in the background, resetting app preferences, and wiping the dalvik and cache with TWRP. None of these has had any affect.
I really don't want to wipe and redo my entire setup, but it's looking like I might have to. Or even downgrade from 4.7.6 to a previous version.
I would appreciate any help and/or suggestions.

None here, been running 4.7.6 for a while. Mine is rooted, my wifes phone is stock, also running fine. Both average 7.5-8 of SOT.

No issues here.

Wow. Since updating to 4.7.6 I have been waking up in the morning to "xyz app" is draining your battery. Usually it is drive which I never use and other times its play services but its nothing like what you are experiencing. My setup has been exactly the same for over two weeks with no added or removed apps, the only difference is the update from 4.7.5 to 4.7.6. I had it dialed in where I would lose 2% overnight consistently but now I have apps draining my battery overnight and the loss is considerably more than that. Hope you get it sorted out :good:

Have you tried better battery stats app to check what's draining your battery? I use that app and it's pretty good.
My phone setup is pretty much like yours, just root with magisk and xposed , no issues here. I'm on stock recovery but TWRP shouldn't matter too guess

Do 1thing i also updated using VPN and m on 4.7.6 version but the battery life is great. I am not rooted just on oxygen Os 4.7.6 without greenify or any such apps. The battery is amazing always 7 to 8hrs and more slot easily. I just cleared cache from recovery and storage after updating and its also recommended on Oneplus site to clear cache after updating. It worked for me when previously i had battery issues . Try it should solve your problems.

Updated to 4.7.6 (full zip via stop recovery) when I got the phone (a week ago) and did a factory reset. Battery is very good for me.

I had this issue on my pixel and nobody seemed to be able to help or offer an explanation, your case sounds extreme like mine was, you could literally see the battery percentage dropping 2-3% per minute and the phone was running super hot.
No idea of the cause but I fixed it by a full wipe of everything, internal storage included, reinstalled everything from scratch no backup app or cloud or anything literally everything clean install.
Hope you get it sorted.
Edit -to clarify, when I tried a clean install of the ROM wiping data cache and system I still had the same issue when i had restored my setup, even in different ROMs, it was baffling. For me it seemed to be wiping the internal storage that cured it, I just backed up pics and anything else I didn't want to lose to my pc just wiped the lot, redone my whole setup from scratch and problem solved.

Just an update in case anyone ends up having the same issue. I fixed it by disabling WiFi. I have no idea why WiFi is causing the severe drain it does, but now I can easily go three days on a single charge and get 6+ hours of screen on time. Even though my phone reports a poor 4G connection almost all the time.
I hope this issue gets magically fixed in Oreo in the same way it magically started in 4.7.6.

That's weird, my phone is connected to wifi a good part of the day and I don't have battery drain. Wifi was on for 22 hours and I have 55% left. The phone is close to 2 days without a charge. I usually get 2 days out of with with normal use and 3 with lighter use.
Have you tested with an app like "Wifi analyser" how is your reception ? I guess it would eat more power with poor reception.

I've had my phone for 3 days, just started, I did the update and a factory reset directly.
I did a test by cutting the mobile data at night and over 8 hours I lose 1% on the battery.
So for me it's very good! :good:

4.7.6 here, not rooted, no such problem

I have this problem too. AndroidOS seems to keep downloading something in the background. I was able to make the problem go away by setting a static IP address in the WiFi settings.

I have used my Oneplus 5T for 8 month,recently the battery is total terrible ,for not use ,and just open one app,it drops battery from 70% to 17% in 3 hour !!And i charged it in 43% ,again drops to 10% in one hour ,then in mins closed without any battery.What a big joke ,i contact the customer of Oneplus ,respond very badly and does nonsense .Mine is 8GB 128GB android 7.1 ,a total rubbish now.Anyone in the same occasion?

Then please do not whine about having a bad battery life. Or when you do not want to update (although your reasoning is not logical as I am on 8.1 latest offcial which is working flawlessly) you could try doing factory reset.

I had OP's issue.
Clear Google cache
Clear Google Play cache
Reboot into recovery, clear cache.
I'm not sure what is required but I do all 3 and it fixes the Android OS drain. Fewer steps may do it? Never tried narrowing it down. My wifi is always off. Location (high) always on. (history/tracking off) App auto-update off.
Based on my circumstances I have a feeling it has something to do with google play app update notifications not coming thru due to bad signal but that's a guess.

Battery Drain following Oreo Update, even after update to Oxygen OS Open Beta 5

I have a Oneplus 3 and I have been quite happy with it .. up until got notified for an update to Oreo a few daya ago.
Since the update, the battery drain on the phone has been pretty bad and even when I am not using the phone, the battery is draining much faster than it should or was.
Yesterday I tried searching on Oneplus forum to see how to fix it, and saw some post suggesting to update to Open Beta 31. I downloaded the update the manually updated the phone, and the battery drain still seems to be same.
Fyi, my phone is not rooted.
Please see the image below for battery drain graph..
What I can see is that even when the screen is off, and the wifi is inactive .. the phone is still awake and not seemingly going into deep sleep mode..!!
Can anybody please help how to solve this issue?
Thanks

you could try better battery stats although it is a root app to find what is keeping the phone awake, i think you can use adb to grant the permissions for it to work without root or you could factory reset that should sort it out

From the screenshot, I am able to see that you have a very patchy mobile signal which is one of the reasons for the drain .

Well, the signals have been same even before the update. The battery drain was not like this before.
In the last 8 hours, with little use the phone went to about 36%..
Now I can do a factory reset but it's an annoyance because all my data would get lost, or I'll have to backup and restore using some means.

I have noticed that with an incremental update, things get sour on OP3. The best bet without losing data would be to clean flash the full ROM after wiping system, data (excluding internal storage), Dalvik and cache. I am sure your issue would be gone.
I always clean flash and have no such issues.

100% App related. I am getting great battery life on Oreo 5.0.1 by using Greenify. Maybe 3-4% overnight.

Just because it worked before doesnt mean it will work the same after an update. Mainly with this OEM.

Hi,
I've tried clearing the cache and also deleting everything except personal data and reinstalled the update 31 multiple times. Still the same problem.
The battery is draining at about 10% every hour regardless.
Can anyone advise what else can i try?
My only doubt now is if the update 31 file is the right one to install. I'm assuming that because the file is approximately 1.5GB it is a full update rather than a incremental update.
If that's not the case, can anyone tell me which file to install as the full update?
Another problem I have noted since the update is that the Camera does not work. Not sure why though.
If nothing else works, I'd be forced to try and downgrade to android 7 though I'd prefer to have android 8 - if it works and does not drain the battery this much.

You say that you have the OP3 but the heading of this thread refers to Open Beta 5 and then you say that you clean flashed Open Beta 31. Which is correct, OP3 or OP3T, OB5 or OB31? No wonder you are facing issues.

Hi
The phone is Oneplus 3
It prompted for auto update to Oreo, which I did.
Then started battery drain issues.
After reading forums, I updated to Open Beta 31.
The battery drain is still there and I have reinstalled Open Beta 31 couple of times which includes deleting everything from the phone excluding personal data, music etc.
I have cleared cache as well.

I repeat, your mobile signal is one, if not the only, heavy drainer.
Install BBS, grant permissions through adb, run it and take an idle dump (as described in its thread) and attach it in the BBS thread. Someone there will study it and identify the culprit/s.

I've installed Bbs and here's what it shows:

It shows something named video2 is keeping the phone awake most of the time. I also found that the phone cpu is awake most of the time rather than being in deep sleep.
Looking on the internet, I can't find what video2 is!!
Any ideas?

Also just found that the YouTube app is also not working. I google'd and found many people have reported the same problem, and have been suggested to do a factory reset. So I've just done that as well and it has still not helped.

Here's another screenshot of betterbatterystat showing the same issue :

This shows that the phone is not going into deep sleep most of the time, as video2 is keeping it awake. Hence the battery drain.
Any ideas of what I can do to solve this please?

Tried a reboot? Don't use any force dozing apps or block wakelocks.

Yes, rebooted the phone and I am not using any app to restrict wakelocks or force dozing any apps - apart from what's inbuilt in the Oreo os.

It's known that Mobile Data can be a really big drainer. I easily go from 0.6% per hour on WiFi to +2% on mobile data, especially poor signal as you have shown can drain even more. You could try using Greenify with Shallow Hibernation, it doesn't kill apps it only restricts them from doing too much in the background, you could try blocking the wakelock with Bluspark's build in wakelock blocker. But I am highly against blocking things that you don't know (Can cause more wakelocks, random reboots etc).

If Video2 is similar to Video3 is then most likely camera related.
Maybe some app is using your camera and doesn't even let your device sleep. Which could make sense since even being awake all the time 10%/h drain is way to high with the screen off, so probably other hardware is being used.
Check your apps, you might even have malware installed. See what permissions was each app.
I'd recommend to backup your data, do a factory reset or even wipe system partition (although you need TWRP for that
Since you mention that YT is not working another possible option is that is some playback video related.
Same thing, backup and factory reset. Install each app with Playstore and don't restore backups.
Maybe when you backup your data into your PC run some kind of Virus Scan over all the file just to be safe.

Battery drain too fast screen off

Hi guys i have my pixel 3xl and my battery is drain too fast when i dont use it in night fo exemple a left him 100% after 6hours i found him 70%
I chek if thers is an app in background and nothing i Factory reset it 3 times and same thing

Let it drain down to about 10%, and then check the battery stats to see what is high on the list. I get less than 1% an hour, and have for the longest time. Running Android 11 since beta 3, and now official.

Hi! I got exactly the same thing with my Pixel 3 and got the same issue, it seems like our device cannot deep sleep. Here is my battery usage and wake lock on EXKM (Running latest Kirisakura, screenshot attached)

Also mine, last night it was 100% then this morning, when i checked it, its already at 95%. Also i noticed that my 3xl now is draining too fast, any tips on regarding this to save or extend my battery? Thanks guys

First week(nearly) after factory reset or flashing img your google play services should drain too much battery which is normal as settings are calibrated, usage patterns adjusted, small updates installed etc.
Most battery issues are related to some rogue app, bad signal reception(it does not need to be full bar, even selected frequency by carrier or phone) or confused google play services. If it is google play then root needed to find root cause(pun intended )
For my case a full day with 1h+ gaming and whatsapp, phone and other stuff 4hrs sot and generally less than %20 percent battery at evening to start charging. You should be happy if you are near this values.

Hi! Thanks for the insight, I'll try to wait until a week and going to post an update here! Just curious because I can't find any information about the kernel wake lock that constantly occurring on my new phone
Edit 1:
So after a few days of searching, I found out the one who cause the deep sleep issue was my modified settings for the Entropy (I modify it via EXKM), after I set it back to default the Deep Sleep issue completely gone and I can stay 0.2 ~ 0.3%/hr when the phone is Deep Sleeping
I hope my issue can help you, and try to reflash it via fastboot with the latest (Android 10 / Android 11) pixel image just to make sure that there is no corrupted data

Android 11 update - battery drain

Since update to official Android 11 version I'm getting serious battery drain:
- overnight drain - 10% (WiFi, 4g and bluetooth off)
- 3.3% drain per hour
- according to GSaM battery the main culprit is...Chrome?
So I've tried to:
- clear data and cache for Chrome
- force stop
Same behaviour.
Anybody else?

The users are reporting of unexpectedly high battery drain when the Google started pushing Android 11 update to the Pixels last month. Google is testing a new feature on Android 11, in order to improve battery life. This feature will allows users to freeze apps while they're cached, preventing their execution and improving battery life.

I don't think it affects everyone. Maybe exynos? I get the same battery life now as before upgrade 11, I use opera browser. I got the 8gb snapdragon version.

I do have Snapdragon version.
As per battery stats the issue seems to come from Chrome.
My only solution here it would be a hard reset but I don't want to install everything...

Is this update One UI 3.0 or 3.1?

I don't use chrome anymore battery hog

It's One Ui 3.0
Disabling completely Chrome has solve the issue for me.

Ok no issues for me thus far seems to be the same before update, i also have chrome. I will monitor as well, if so i will switch thanks for the heads up.

I have the same issue with my S20+ (Snap). The amount of time spent on Chrome is same (or much less) than on FB or Messenger but the usage is huge. Every 10 minute of using Chrome drains 3%. Thats a lot say you browse the webs for an hour (close to 20%). I already uninstalled, reinstalled, clear data, cache, whatever it is. It still exists and is very annoying
