OxygenOS 3.0.0 Excessive Battery Drain from Android System

My battery life is almost the same as it was back on CM13. My phone is rooted and running xposed V81. I clean flashed 3.0.0 using the modified TWRP. I'm only getting around 2 1/2 hours of SOT and ~10 hours total usage.

Will do at the end of today.

Hi,
I have been facing similar issues, I have been using my OP2 for the last 2 months and has continuously got an avg. Of 3.5 hours SOT even when I am connected to WiFi throughout the day.
I rooted my phone and greenfied FB, Messenger and few other apps, used POWER Nap, yet I can't get more than 3.5 hours at all.

In my experience stuff like Greenify and Power Nap do more harm than good. For Facebook i would use Facebook Lite or the mobile website.
To your logs: i don't know what app you were using exactly but in both logs you have your CPU at highest frequenzy for over an hour. If you are using an App which needs the CPU to run on its highest speed it sure is using a lot of Battery. I don't see anything abnormal in your logs. Maybe head over to the BBS discussion thread and show your logs there.

The best battery life I got so far is to run on STOCK. 4.5-5 SOT on LTE only (surely longer if on WiFi)
with CM13, I get about 3.5-4h SOT (standby drain very fast).
With xposed, amplify, greenify, power nap, various kernels (AK, boeffla) all didn't significantly improve anything at all. The placebo effect is really strong.

Same here. OSS 2.2.1 was way better. I installed new hydrogen os MM and I have best battery than OSS 2.2.1, for now, I have to do more test but it's looking amazing.

OOS 3 has been the best for me in terms of battery. With moderate usage and sync on I frequently get over 5 hours sot over 3 days of use vs 1.5 days on 2.2.1. Doze is fantastic and I barely lose 2% a night.

Can you explain your point about the wifi issue?
I'm running a clean install of 3.0.0 and it's LOVELY, but my battery is terrible.
Would be interested in ways to improve if I could understand the wifi problem.

Please, while complaining about f**ked up battery life, do something that benefits us all.
Post screenshots of your battery usage chart from android settings and post logs from apps such as BetterBatteryStats.

I did try, however i'm "new" to the forum (posting) and therefore could not attach or add links .
Essentially though Android OS is showing:
CPU Total: 1h 15m
Keep awake: 57m
It's also 15% of my total battery usage.

Don't you have idle drain because of network dropping? Since marshmallow, I've had that issue that once the device goes off to sleep, the network bar in the battery is either yellow, or orange. And it isn't that I don;t have good reception, I never had this issue before upgrading to OOS 3, otherwise the OS is really good.

From what I've found, each time I turn off wifi my wakelock increase by 2 minutes under android system/oxygen, more specifically "connectivity service"
I believe it's just the system trying to find a data source after wifi is turned off. (my data is off)
So given this, its best to leave wifi on unless you're gonna be in a place with no wifi all day, turning it on and off will cause wakelocks

I notice this as well, reception is sometimes green and mostly orange/yellow vs solid green on 2.2.1 but it hasn't seemed to affect my idle drain. In fact it has actually decreased from 2.2.1 where I would get a drain of at least 5% every 7 hour sleep period even with airplane mode and power saver enabled. Now on 3.0, drain is more like 2% with wifi over the same period.
Additionally, someone stated that the orange/yellow reception phenomenon was marshmallow actively trying to conserve radio power when its not needed. I don't know how accurate this is but it might be true

Weird, on OOS 2.2.0 I used to get hardly 3-4 % drain in around 7-8 hours, on OOS 2.2.1 it became more 5-7% and on OOS 3.0 I get 8-9%.. Very weird... Isn't OS update supposed to make things better? Also I did do a clean flash of this particular rom and I am all stock, havent rooted the device yet.

And also, weird thing, the phone is not awake during the deep sleep, atleast not showing in the battery graph.

Could you plz explain did you do any changes to have 11hrs of SOT??

I'm desperate, Android system and Android OS are draining my battery, I can't get to the end of the day and when using it it gets hot very often, despite not using hard apps. I tried to flash Hydrogen OS, CM13, PA, using greenify, etc... facing exactly the same problems. Can anyone help me?

9-10 hours of SOT on Moto E. How ? Here is how.

I use Temasek as my rom with greenify, amplify, kernel audiotor , appopsxposed and tasker.
On custom kernel Clarity r26 (permissive)
My brightness is set to 12 when I am indoor or after 5 pm. From 10 am to 5 pm I have automated brightness to 15 when outdoor.
Once my screen goes off wifi or data is turned off. My phone goes to Airplane mode from 12 am to 7 am. Once I am home wifi is turned on and data service is disabled.
I am sure most around here knows how to use amplify and greenify so I wont go about explaining the same.
With appopsxposed I have disabled all the location permissions of all the apps including play services except tasker as I dont use them.
In the next post I will post my kernel settings. I have tried and tested this multiple times and the results have been more or less same.

OMG are you serious ? This works on a depleted battery as well ? You can get 10 hours of SOT with a newer battery. And use Kernel audiutor and make sure you are using clarity r26 with permissive.

To ensure you dont drop much while device not in use ... You should use amplify and greenify all apps that you have installed. Kill Google play service and ensure the apps you greenify are not waking up.

Battery drain issues

The only working solution for now: flash Lollipop. It's not perfect but it heats and drains battery much less than Marshmallow.
I'm creating this thread so that we can discuss battery life issues and look for a solution.
There is a popular thread on this topic but it is marked as solved, and while the original poster's issue has been solved there are many others that remain.
For some people the issue was solved when rootkernel was updated to fix some bug. But that was a long time ago, and some bugs are obviously present even in the latest kernels rooted with the latest rootkernel versions. It's still unclear if the issue is present on non-rooted kernels.
I will create a poll, please consider answering it to help clear the issue.

By the way, has anyone encountered any issues on 5.1, or is it just a Marshmallow issue?

Partial solution: I installed OM5Z kernel and it has significantly improved battery life on Marshmallow.
While it's still much worse than what you would expect from a Sony compact, it's not awful anymore. The phone can go a day (no heavy usage) without charging now.

Stock or Xpower 4 ,rooted or not dosnt metter - i have a drain every night(8-9 h of sleep) about 5-7% in airplane mode.Try BBS and WD now but seems phone sleep good.Think i lost about 15-20% at 24 hours
On Xpower 4 lite as is...with andro kernel v36 same issue.And i dont have any other soft. Goggle sync and other garbage is off.
Dont now where is may be problem.

Try Xpower3, it looks like X4 got more problem. I'm running v3.0 Full(stock kernel), when I set it to airplane mode over night only drain 1~2% everytime but I've installed greenify donated and used xposed amplify.

For anyone reading this thread, are there any other things people can note about their setup?
Country? Carrier?
If you are having issues, what apps do you use? Do you have a microSD card and if so, what brand/model?
If you are not having issues, same question about apps and microSD card.
I have seen on my phone the higher Android OS CPU usage which is of course the black hole of power drain for many people. I still need to do more scientific testing of usaging or avoiding apps to see if anything is triggering the drain.
T-Mobile US customer here, typically on Wifi at work/home also with T-Mobile cellspot for signal strengh. Standard apps for messaging and social media including Snapchat (bad app for power usage) but avoiding Facebook for now. Google Now Launcher.

Stock firmware, rooted stock kernel, don't have issues
1) Z5 was incredibly hot out of the box
2) Wiping the system, rooting the kernel etc. fixed this but gave me awful battery life
3) Installing the modded kernel then fixed the battery life (found here: http://forum.xda-developers.com/z5-compact/general/9-battery-drain-overnight-97-deep-sleep-t3382145)
I can stretch it to 3 days with light use, a day of heavy use can put me back 50-60%
I'm from the UK with the UK unbranded official ROM.

I found software RealBattery and CaliBattery.Try this too.

I have also recently upgraded from Z3C to Z5C with stock Singapore Customized FW, but I live in France (ordered from eBay).
Weird thing is that during the day it loses may be 30-40% in 6 hours, but every evening after I come back from work, phone overheats with battery up to 50 degrees and drains 30% in 1 hour...
In stats, it shows Android OS using most of battery and keep awake being 80% of up time...
I had same issue on Z3C with last 6.0.1 MM.
During the night I usually lose 5-10%.
Any advice?

The problem is that I have E5803, and not E5823...
Will the HK FW work on it? It's only for E5823 I think (according to Xperifirm)
Also, what exactly should I do - I should wipe everything when installing using Flashtool right?
Should I also do reset after installation?
Can I restore my backup or you would recommend to make a clean install of the apps as well?
I don't want to lose data of apps.

Before reflash or do someting try to use clean frimware without your usually apps.Do factory reset.Dont forget to make backup of your current state phone i f you need.
I think problem exactly in your apps.
I have issue with night drain and i try HK frimware on my 5823 and i dont feel any difference.

Okay, now that I have gathered some statistics I take back my words about significantly improved battery life. It's slightly improved and still awful.

I'm using stock fw, but have deleted about 60-70 apps I don't have any use for. I also use OM5Z kernel. I experience no drain what I know of, usually have about 3 days with normal use.
The only issue I experienced is that the phone totally crashed a couple of times. I can't wake it up at all, and it doesn't take any charge (LED doesn't lid up). I have to use the reset button to reboot it. But so far, it's a small issue

Sudden huge battery drop

Hi everyone,
I have a huge problem with my Huawei Mate 8.
I was using Android 6.0 without any problems, but as soon as I updated to Android 7.0 I experience sudden huge battery drops. And I mean really huge. For example in 2-3 seconds it can go from 50% to 2-3% and shut down.
If I leave it for 3-4 minutes and then start it again it goes back to normal.
I saw some recommendations about factory reset, so I have performed factory reset on the phone but the problem still exists.
The build number is NXT-L29C432B581
Take a look at my battery usage screenshots. Have you seen anything like that? Do you have any idea what causes the problem?
Thanks

Afterall it turned out to be that the battery was dead.
Replace it and you will be fine and the batterylife is just like new.
Hope that this wil help you.

Hi everyone,
I have a huge problem with my Huawei Mate 8.
I was using Android 6.0 without any problems, but as soon as I updated to Android 7.0 I experience sudden huge battery drops. And I mean really huge. For example in 2-3 seconds it can go from 50% to 2-3% and shut down.
If I leave it for 3-4 minutes and then start it again it goes back to normal.
I saw some recommendations about factory reset, so I have performed factory reset on the phone but the problem still exists.
The build number is NXT-L29C432B581
Take a look at my battery usage screenshots. Have you seen anything like that? Do you have any idea what causes the problem?
Thanks

This type behaviour usually occurs when a battery cell becomes damaged. It is then not a software related issue but a hardware one, the solution would be to replace the damaged battery with a healthy one.

to be honest, that was my first thought, but this problem began immediately after upgrading to 7.0. Not a week after, not a day after. Before that my battery was perfect. It was able to last 1.5days with the wifi and mobile data on, and never have this huge drop. I would expect it to have extensive drain before getting damaged, or at least show some signs.

Go back to Android 6.0 and see if the problem persists. If yes, then it is a battery problem...

I'm having the same issue with Nougat in my Mate 8 - battery gets to 30-50% and then drops like a stone - there are reports of this on Chinese Huawei forums as well going back several builds - I have the NXT-CL00 version from China Mobile. I haven't found a source yet for the OEM firmware/guide to flash back to Marshmallow to see if that fixes the problem. Would also like to know if the phone can be flashed to the global firmware for this version rather than having the stock China Mobile version.
As a follow-up, I was able to return to the stock Marshmallow/EMUI 4.0 Firmware via the Huawei HiSuite Application - the download was available through the application.

I've been experiencing this problem for a while too. Did reverting to 4.0 fix the issue?

Switching back did not help, unfortunately. Everyone else with the issue I've read about claimed there was a battery issue and replaced the battery. I have one on order from China. Good luck.

I have the same issue as well...device shuts itself off at around 39% battery power, not able to turn it on without charging. Once it is on, the battery shows only 2%. This is obviously a sudden battery drops.
Can you post if replacing the battery does help? and where to get it replace in North America?

Do a battery calibration and see if it resolves...

can you solve the battery[emoji367]problem with replacing battery[emoji367]?

I had the exact same problems with my Phone. I replaced the battery with a new (original) battery. Since then the phone has been running like the day I first unboxed it. It's fairly easy to change yourself. It only took me 10-15 minutes.
So for me the problem got solved, replacing the battery.

Battery issues with custom roms

Hello everyone..... I have flashed 3 custom roms on my phone rr aex and lineage ..... In all three roms i had the same problem which i didn't have on stock rom, i.e. battery. In the custom roms i get 1%drop in every 3-4 mins while screen is on. And while the screen is off it is okay bur sometime while the screen is off too the battery drops 1% about evry 3 mins.... This didnt happen in the stock rom , on that i got about 1% drop in 9 mins plus the standby time was amazing..... So i wanted to ask why is this issue there? Is there a problem with the custom roms or there kernels? And should i flash the stock kernel on lineage os 15.1, will it make a difference??what else can i do for better battery? Thanx in advance:good:.

I believe its with the ROM itself. The way the ROM manages BG processes and deep sleep cycles, u can improve battery with the custom kernel ( ko kernel ) but you have to sacrifice a bit of performance , by twerking the CPU profiles using kernel adiutor , but even then it won't make a huge difference.
I'd stay if battery is ur concern, go with pure aosp or stock . I hope the issue is fixed soon , the dev have acknowledged it.

Im using rr rom with ko kernel,greenfly and amplify.it gaves me about 10 hours SOT.battery drops at 20% after 2 hours using SOT

https://forum.xda-developers.com/asus-zenfone-max-pro-m1/development/kernel-t3817910
This is the ko kernel for zenfone max pro m1..... Download it and flash it from recovery....
This will fix your battery issues
Also if you are having battery issue check and see if any of your apps is eating too much battery in background because when i flashed the magisk module of youtube vanced app on the ko kernel the battery problems started again and when i removed it the battery was fine again?

Den u can flash aosp extended or dot os also u can calibrate ur battery it helps me too

I have found a better kernel than ko kernel
https://forum.xda-developers.com/as...velopment/x00td-rawwork-kernel-v1-0-t3811851/
I am using this kernel now and i found that battery life is better on this one and the ram management too..... With ko kernel i had like 1300 mb free at all time but now with this kernel there is 1800 mb ram free at all times ..... It has made the performance better with good battery life.

Hello i can see that your system has used very less battery than mine .
In your screenshot system shows only 17 % battery used.
My system used up 34% battery with 6hrs 5 min screen on time....
Why is that ?is there a problem in my phone or is it just cos we use pur phones in different ways.

It does depend on how you use your phone. What is important is to figure out if your phone is using battery on something that you don't expect it to. Use better battery stats to see if your phone is using battery on unwanted stuff. Now I am getting 15h battery.

Nopes, it shouldnt be that much. Check your partial wakelocks or kernel wakelocks. Sometimes i have cdfinger_wakelock which is taking up battery. I also have ActivityManager-Sleep wakelock which is also consuming too much battery. When I restart things start working(sometimes). Sometimes I don't have a clue how to stop them.

This happens with me too..... Sometimes when i restart it after charging to 100% then it doesn't consume any battery while the screen is off even for hours but sometimes while sleeping and even when screen is on the phone consumes 4% battery in 12 mins. I hope there will be a permanent fix for this in the future.

That's probably from buggy ambient display. Try turning off n check if it improves. I am no expert in wakelocks. I am myself figuring out stuff. You can ask people in better battery stats thread. They might help us.
