Android 9 rollaback to 8 because of battery drain - OnePlus 6 Questions & Answers

Hi!
i flashed the full rom with twrp and updated to 9.0
Almost a week playing with the settings but is still have a big battery drain. The phnoe is 2 months old and did easily 1 day with a full charge. Now i can t reach the evening....
Any tips how to go back to Oreo without losing data?
Please help
thanks

Are You sure some app doesn't crash in the background or something? Since Pie, I get 12-15 hour SOT every day. And I have Google AOD on all the time.
Maybe download Matlog from Play Store and check if there's anything crashing. Just look at the live logcat for like 10 seconds and if You see new messages popping up every second(like a lot of them) then take a screenshot.
From what I've seen, most people get around 8 hour SOT on Pie.
Don't give up just yet .
Edit: and I'm not sure if it's possible to go back to Oreo without wiping data. Most stuff would probably crash a lot.

Theres unfortunately no way to rollback to Oreo without a complete wipe. Oreo has July Security patch, whereas Pie has september one. So you HAVE to clear all contents of your phone, otherwise it will be encrypted due to security reasons.

Do You have root? If not, then You can use adb logcat on Your PC. But if it's too difficult, then You can download GSam Battery Monitor and it should tell You if any app is draining Your battery.

Battery drain (Google account manager)

Let me start off by saying I was so happy with this phone and its battery life but the past couple of days I've seen it drain more than usual. Upon checking I see that Google account manager is responsible for this.
Anyone have an idea what caused this? and how to fix it?
i noticed the same on my chinese mate 9 however the % is below 40 still, from what I can see on my case is the google photos app causing all the noise I had disable synching over cellular data but haven't seen any improvement so far. I did that 2 days ago
Same here on my P10.
How many Google Accounts do you guys have linked? I currently have 4.

Thx for your replies guys!
Meanwhile I accidentally found out that this might be the process what is on other phones the Google Play Services.
I tapped on the Google Account Manager entry and scrolled down to the bottom of the next view and there it is..
Still I haven't seen the "Googl Account Manager" process ever before I assume that Huawei handles or at least displays the processes differently than others (at least Samsung) do.
For me it's a good thing since I see way more processes sucking battery than my SGS7 showed me.
Remembering the battery drain on my SGS7 the Google Play Services had pretty similar battery drain like the "mother process" Google Account Manager has on my P10.
So I think that's it
What do you guys think?
I have the same problem, lot's of times it's a Google calendar fail sync or Google fit fail sync because the system close it and when Google account has do a sync that's impossible because the apps are closed so I'm testing to not force closing Google apps. I will tell you my results

Still shouldn't use that much. Literally it's the most used one. One hour of screen use today and I'm down 25%
My Huawei watch is the only thing connected. No autosync no nothing. Used it minimally. My note 5 after last update and a reset lost maybe 6% all day. Android OS n kernel aren't an option. It's not on 7.0 tho
Does anyone have a solution for this? It is horrible since a few weeks (no update in the meantime, no other apps installed): Google Play Services (Google Account Manager) are very active, device gets hot, reboot helps for a short time, but almost every day I have a huge battery drain. Before the last weeks, this was not a problem at all, battery usage was super.

Do you have developer options enabled?
I've had the same problem, after diasabling developer options it seems to be somewhat better but not really cured.
I also enabled in settings the automatic memory and data cleanup as I've found that cleaning all app caches helped for a short period of time.
I fixed my by doing factory reset. Now everything is back to normal.
Also before I had a problem that whatsapp didn't show messages if I didn't open up the app. This issue also got fixed the same time.
I'm suddenly having high consumption by media server - have no idea what it means and the phone is quite hot.

mediaserver can be due to listening or streaming music, or indexing music.
its fairly normal, however if your rooted you can disable it in an init.d script.
stop mediaserver works.
or
su -c pm disable mediaserver

Thanks, I've been listening to music all day. I'm not rooted so I guess I'll have to keep on with it.
Shut down for a while then restarted the phone and it's no more getting hot.

ive still got issues with android os using the most power. i only get 6-7 hours max screen time. i use my huawei watch via BT. latest update for the USA 183
Seems to be getting worse. Now I'm slated max 27 hours. WTF
in reality battery life never gets better. The constant discharge, and charge rates only put wear and tear on the battery. It would great to have the ability to swap batteries on the fly.

Having bad battery life on Nougat? Check this.

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------​What I have right now out of Doze are "Bluetooth MIDI Service", "Bluetooth Share", the "Clock" app and two other Clock apps.
I am not sure how effective is the method listed below after the last update. Stay tuned.​​
Also I think the current version of Facebook Messenger is draining too much battery.
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------​Hello everyone,
when I bought my Zenfone 3 ZE520KL, I was amazed by it's battery life. I could easily get around 8 hours of SOT in a single charge with moderate usage. My device was running Android Marshmallow 6.0 out of the box, but performance wasn't as good. On Nougat, performance is much better and faster, also I used to get some lags and frozen screen, the capacitive keys also sometimes froze when I was charging my phone, but now I don't get issues like that as often as before. Interface is so much more appealing and I love it.
But what about battery life? I started getting around 5 hours of SOT.. which is still good, but not really close to 8 hours. I thought a lot about these 3 hours that were missing so I decided to start investigating. I wanted to share my findings with you so maybe you would know something that could help.
It's been two weeks since I have been testing out different things. The apps I used to do my research are:
Carat. What I love about this app is the process list. It shows exactly which apps and system processes are running in the background, so I can control them very easily.
Greenify. Thanks to the Carat app, I can see which apps continue running in the background, so I can use Greenify to hibernate them after I'm done using them. (Examples: Youtube, Snapchat etc.). Also I bought the Donation Package, and unlocked the other modes using adb commands (my device is not rooted).
BetterBatteryStats. This app is usually used to detect wakelocks. I limited the Google Calendar App from syncing so it doesn't use too much battery in the background. This app is paid in Google Play but you can get it for free from here.
What I did to get better battery life:
I excluded the services, that were always running in the process list from the Carat App from Doze. Apparently, the new Doze in Nougat gives us permission to optimize more system processes and services than before, which can backfire - Doze starts trying to kill processes that can't be killed, and this results in consuming more battery juice than saving it.
How to enter Doze settings and make the following changes:
Go to "Settings" > Select "Battery" > Tap on the three dots at the upper-right corner > Select "Battery Optimization" > Select "All Apps" > Find and tap on the Apps/Services/Processes I have listed below > Select "Do not optimize". The other apps and services should stay optimized.
The apps, processes and services that I removed from Doze are:
Android Services Library
Android System
ASUS Calling Screen
Bluetooth MIDI Service
Bluetooth Share
Camera
Clock
com.android.smspush
com.asus.keyboard
com.asus.shim
com.qti.qualcomm.datastatusnotification
com.qualcomm.qti.tetherservice
org.codeaurora.bluetooth
org.codeaurora.ims
com.qualcomm.qcrilsgtunnel
ICESound Service
Mobile Manager
MobileManagerService
System UI
Telecom Service
Telephony Service
ZenUI Keyboard
ZenUI Launcher
Some other apps that I'm using: Do It Later, Greenify, Messages, Nova Launcher, Timely, Weather.
Please do a full charge to 100% afterwards and check if the battery still drains as quickly as before. Your feedback will be greatly appreciated.
I am already starting to see improvement in my battery life. I was losing around 2% on Stand By and battery was draining fast when I was using the phone, but now I lost 0% on Stand By overnight and 10% for 1 hour of SOT (before this I was losing 10% for 30 min. of SOT). I am still trying to figure out which services exactly are causing the drain, when they are being optimized. Maybe the services, included in the Android System? (Check them from Settings > Battery > Android System > Included Packages). I deleted Facebook and Twitter apps and started using them from Chrome (almost the same thing, I quickly got used to that). Please check the updates below for more info and share your opinion or advice in the comments so we can all reach a better experience with this amazing smartphone.
Thank you for reading!
Update1: 6h30min SOT with 30% left (917mAh, 35%), but I will have to charge now. I have been messing with Doze a lot, maybe I'll get more clean results later. Progress has been made though, at least with my device.
Update2: Something interesting - my J-Score with the Carat app before and after starting this experiment: http://i.imgur.com/Q8u6HBD.jpg
Update3: There is a battery drain when making voice calls - 226mAh (7%) were lost because of 43 minutes long talk time.
Results were worse after testing with the second list removed, although there wasn't much draining with the screen on: SOT - 5h20min for 70% of battery (752mAh, 20%).
Update4: com.android.phone appears as a wakelock at BBS (Wakeups:8). Also 2h30 SOT for 30% used battery (100-70%~408 mAh). I'm updating the list and trying again.
Please note that my phone is updated to the latest firmware WW_Phone-14.2020.1703.28-20170410.
Update5: com.android.phone is still an active wakelock (Wakeups:14), but SOT is 2h34min for 30% used battery (100-70%~343mAh). At 30% battery left, SOT is almost 6hrs(28%~787mAh), Device Idle is at 10% (291mAh). The MobileManagerService is causing way too many wakelocks and is probably the reason for the high Device Idle battery usage.
Update6: MobileManagerService is no longer showing as a frequent wakelock. com.android.phone (Telephony Service - Wakeups:9) and com.google.android.apps.messaging are the most persistent wakelocks, other than that battery life is amazing at the moment. SOT is 2h45min for 30% used battery (100-70%~366mAh). I also had 27 min of talk time (4%~145mAh). At 30% left, I have 6h33min of SOT (32%~912mAh). Device Idle is again at 10% (292mAh). We are ready for the final test.
Update7: The results are quite interesting. After removing com.qti.qualcomm.telephonyservice from Doze, com.android.phone stopped appearing as a frequent wakelock at first, but now, at 70% it has 16 wakeups. SOT is 2h22min (100-70%~318mAh), so it's not better. I'm going to try a few more changes.
Update 8: I posted it as a reply here.
Update 9: I shouldn't have put Task Manager out of Doze, I get so much better battery life now. The update is ready, check it here.
Good post, thank you for investigating this, please let us know if you find more stuff or what exactly is responsible for it and an easy way of fixing.

Hello! Thank you for your reply. I'm so happy I could help others and myself with this thread, but I also need to know if you are also seeing any difference. Please check here regularly!
Also, I'm guessing that when you put your system processes and services in Doze, you also decrease their performance, which causes battery draining, as they try to run normally and do their work. Doze is trying to prevent them from doing that. This is my conclusion, but only results will show if I'm correct. If you own yourself a Zenfone 3, please feel free to report if you experience any changes using my method.
Thank you and have a nice day!
Hi, thank you for the post. I have a zenfone 3 here and will try your method.
I'm trying it on ze520kl with marschmallow, it seems working fine. :highfive:
Do you remove the first and second list from doze ? or ate testing with only the second list now?
Nice findings btw

Too early to say, also I got a weird wakelock, and lost 2% overnight. I lost the results (100-90%) after a restart. Now I'm going to update my phone and start again.
I had 8% used up on 43 minutes of SOT, and 2% lost on voice calls (100 and something mAh). I went to bed with 92%, I guess the other 2% were lost on that wakelock and the clock wakelock. These 2% were lost on equal intervals.
It's going to take a while, I'm just using my device normally. I don't have time to be on my phone all the time, also the battery is harder to drain now. At this point, I'm just trying to get better results.
Cheers!

I don't think it is a good ideea to change Doze settings for system services like com.qualcomm.* or telephony*.
In theory, these services should be compatible with operating system and they should work as designed. I would focus on third-party apps who doesn't work well on Nougat.
Anyway, is just an opinion and i'm looking forward for updates

Hello ci6i, I also agree with you, and that's why I excluded all of them from Doze when I first tried this out. At the moment, I removed only those system services, that run in the background all the time. My goal is to find the least amount of system services and processes, that are causing battery drain when the phone is in use.
I am not saying that you should do exactly what I did. It's best if you try out yourself on your own device what works and what doesn't.
I also have only excluded from Doze apps that I use daily. But everyone is using different apps and it depends only on the developers to update them.
You can download Carat for free from Google Play and check the process list, it's very useful. The app itself doesn't use any battery.
Good luck!

I agree with you and i really appreciate your work Yesterday I've installed Carat after i read your first post and today i did new OTA update and cleared cache partition. Let's see how it works in the next few days.
What should I do next, guys? Remove other com.qualcomm/com.android/com.asus services or remove just MobileManagerService from Doze? I'm thinking about the second one, I'm curious to see if ti makes any difference. I think the results from the first test were the best, and the MobileManagerService was out of Doze as far as I remember. Might as well try and see what happens.
It's a bit hard to drain the battery these days, so updates might not be fast. Patience is key!
Yeahh final test!! Looking forward to the result

Anyone has battery draining issue?

Bought the XZs for almost one month. The battery performance seems not as good as expected. It seems even worser than my old phone, LG G2. I tried to change a new XZs and the same problem exists.
Phone Idle always take around 20% of the battery use. Stamina mode is one and 2-3% is gone even the phone is not in use. The same issue even happened in safe mode. And fast charge is not fast at all...
Googled some posts and found that some people, XZ users, experienced the same issue. I have tried uninstalled Facebook and Messenger. Seems not help.
Just downloaded betterbatterystat, I hope can find some cues there later. But if anyone can advice why
You installed betterbatterystats? That requires root right? Which isn't available yet I believe... Guess we'll have to wait for root to investigate this
Seems like this is Android 7.1.1 Nougat's problem.. Is it the Android OS percentage is very high in the battery usage list? Many Nexus devices also having this problem.. My XZs can only get nearly 3 and half hrs of SOT omg, seems like the doze is not working well, saw massive of wakelocks during screen off..

nougat's problem...but seems not seeing people raised this problem in the internet , so i am still not sure if it is my own problem or not..:silly:
my top 4 usages:
screen 20% (screen opened 1hr 35min)
phone idle 16%
chrome 9%
android os 9%
the battery power dropped around 30% after 12 hours and i might just used the phone for around 1.5 hrs only.

Hey guys, after some researches and testings, seems like my XZs is having good battery life now. What I did was go to Chrome > Settings > Site Settings > turn off the Background Sync option. Now my latest full charge gives me 2hrs 43mins SOT with 49% battery left, with 1 hr gaming. Hope this helps, good luck everyone

I've been using Xperia XZs HK version for about 2 weeks.
I use an app call "Brevent" to keep background apps in standby mode when they're not active.
I think there're also some issue with Doze mode on Xperia phones, it drains battery more than I thought......
Then I found an app call "Force Doze" to force it go straight in Doze mode while I shut the screen off.
Now it only cause 1% per hour while I shut the screen off and leave WiFi or LTE on.
Or 1% per six hour while I shut screen off and keep the phone in Airplane Mode(very useful at night).
By the way, both "Brevent" and "Force Doze" does not require ROOT, but they need adb for authorizing their activities.

No, it doesn't.
Brevent only kills process and prevent them from running in background while you have already swiped the app from "recent apps". It does not affect background activities of apps which are currently in "recent apps".
For those apps which requires sync service (for example, "Gmail"), you can set them to "allow sync" in Brevent.
Then these apps would be allow to sync in background periodically, instead of allowing them all the time.

cool, it really helps a lot during screen off! it just took 1 % when i wake up.
I do not have the Problem. All sync enabled, Bluetooth on, really much apps installed. At end of day 37% remaining. Its impressive. 41.2.A.0.219.

Seems like the doze is not working well

Battery drain after Oreo update?

So, after updating to Oreo, I noticed that my battery doesn't last long as when it was still in Nougat. I know full wipe is often the best recourse but I don't want to have to go through deleting all my apps and data and reinstalling them afterwards. That takes a loooooot of time. Anyone else who might be having the same issue? Also, any tips other than full wipe/factory reset would be much appreciated. Thanks!
i met the same issue also
before oreo, my phone battery was last long
when im gaming it almost take 6hour+ to drain off the battery
after updated it drain 40% within 2+ hours
so can i downgrade from oreo ?
somebody know what is the solution ?
Your device is probably learning how you use it (again) and I'd recalibrate the battery (let the battery die and charge to 100% with the device off)
I think you'll be back to normal after a few days
No issue here. My battery is just as good on Oreo, if not better.
Same here. Battery drains obviously faster. There's an app that obviously doesn't know how to behave with oreo.
No issues here, but I did a full wipe and start again fresh.. So far down to 42% at just on 4hrs SOT.. should easily get my usual 5.5hrs or there abouts
Guys always do a factory reset after a major update.
my battery was not good at android 7
but i flashed android 8 with newflasher
and turned on limited background activity and background data usage at app info for all of the system apps and other apps that support this feature.
my battery in android 8 has been perfect
and free ram is about 1.9 gb always

i suggest you to do that

Of course you're 100% right but sometimes it's just too much work. In any case my update settled down very nicely after 2 days.:good:
I disagree 100% with the need to do a factory reset after an upgrade! What, are we on version 2 of Android??? By this time, and with what we pay for these devices (and don't think that the software is free because it's NOT) and with the fact that they have become essential tools for most people, we should NOT have to do a factory reset every time a new(er) version is released and thereby forced upon us! It is up to the OEM to test these things thoroughly to make sure they work as advertised and expected. I do not have an entire day to devote to getting things set up correctly every time this occurs. If the OEM's do not want to test things properly then they should give us the option of installing at our own risk, and not mandating the upgrade.
I agree with you guess my battery is way better now, keeping in mind I have lifelog app and live wallpaper running in the background the whole day, I love 30% since the last time I charged, 6 hours since I unplugged the device and I have 1,30 hours screen on. Oreo is perfect ?

How did you set the limitations of the apps' background activities?

go to setting > apps > app info > touch 3 dot and choose show system > touch on every app that you want to limit it then go to > battery > turn off background activity
for limit background data instead of battery choose data usage and turn of background data
i suggest you to turn off these for all of the apps

It's not mandatory, you could just press cancel ?

Lobotomizing your phone like that beats the purpose of having latest n greatest functionalities from an OEM / Android. Although I wish there was a wakelock adjustment as a default setting w/o root. It all comes to personal preferences. I only limit background activities to apps I almost never use and I let the rest do their thing cause I like some of the google services and also some tasker profiles require a frequently updated context .
As for RAM, it is meant to be used and now android is smart enough to adjust the resource consumption on it's own without the need of a app killer which does a lot more harm.
Needless to say Google Assistant keeps on pushing it's Ok Google Anytime function down our throats. It's now easier to accidentally activate it and they did nothing to optimize the power use of that thing. I tried it thinking maybe it's usable now. But it actually managed to overheat the phone leading to ~10% battery drain/hour (just because i had tv shows playing and it was comparing the dialog to the hotword). Not 'Ok Google'.
Sooo make sure you have that disabled. Otherwise you're in for a nasty surprise in loud environments.
It's better, I would say.

Try this app. Very comprehensive usage stats.
https://play.google.com/store/apps/details?id=nextapp.sp
And don't forget to grant usage permissions via ADB for extended details.
We should post battery drain/hour and SoT.

My battery was at 96% at 4pm yesterday, this morning at 5.30am it was 15%. This is crazy drainage, I used it sparingly yesterday afternoon, it was at 60% by 9.30pm (bedtime). I didnt touch from 9.30pm to 5.30am. 45% drainage with absolutely nothing running. Thats nuts. Has the battery gotten anyway back to normal for anybody? Or is there a fix without factory resetting the phone?

Android 10: horrible battery life, downgrade to Pie?

Battery life on Android Pie was exceptional.
Dismayed by the drain on Android 10, incredibly fast. So far this seems to be linked to WIFI usage, e.g. when (i) downloading podcasts, (ii) calling on WhatsApp or Skype.
Are any of you downgrading to Pie because of this issue? Or have you found some clever settings to solve the problem?

Please check out the same threads I've mentioned here https://forum.xda-developers.com/on...-7-gm-1900-battery-life-t3995649/post80758067
Thank you @strongst, I had bought and installed BetterBatteryStats when I saw you mention it in another thread.
But still curious to know if someone has already been able to diagnose and solve the problem on their OP7 Android 10 set-up, as it looks like this is not an isolated problem.
Yeah im having the worst battery life right now because of idk what in the Android 10 that prevent my phone from deep sleep

(For anyone else who might read this, BBS = BetterBatteryStats, you can download that app here or pay two bucks on Google Play and sign up for Beta for the latest version)
@strongst, since the BBS thread has a thousand pages, can we please check with you that these are 'good settings' to run BBS and get the proper stats for a Dump?
- Default stat type = since unplugged
- Watchdog = OFF
- Active Monitoring = OFF
Thanks in advance for any tips!

I had the same problem. I just installed Greenify and it improved a lot. I don't have root and I keep all apps. I use tasker to turn off automatic brightness after a few seconds of power on.

Thanks to you i finally found that telephony-radio wakelock that always keep my phone awake, but the problem is, my signal is strong but it still waking up my phone :crying:
look at that too, maybe helps you for wifi settings via adb : https://www.androidpolice.com/2017/10/24/google-inexplicably-removed-keep-wifi-sleep-toggle-pixel-2/
also,you can using this app,works on android 9 + 10 : https://play.google.com/store/apps/details?id=na.komi.piefi (we take back the three options wifi)
Close Google Location Sharing is the worst thing for any device - check your ruter again
(if we have rooted device,we can do a lot through buildprop for better battery management)
Personally,until now I have not battery problem on my op7 oos 10.0.1 gm57aa but I don't use social apps,WhatsApp etc...
I just recently bought my OP7, previous phone was the PocoF1.
For my usage I'd say battery life is pretty great!
I'm not rooted (yet) and I'm updated to the latest version of OOS.

Your dump file has less than 6h of recording time.
You have a very bad mobile signal:
Poor Signal (): 19 m 12 s 5.9%
Moderate Signal (): 3 h 38 m 9 s 67.1%
I had terrible battery life on Pie but as soon as I upgraded to 10 I probably get about 3 extra hours of out of it each day (depending on what I am doing.)
Quick question:
I have a full TWRP back from before upgrading to Android 10.
Are there risks of using that backup to go back to Pie that I should be aware of?

Yes, the risk is high, it's not recommended to downgrade using twrp backups.

Yes it's risky. But it should be possible as follow;
1- Downgrade with the official *,zip file (search on oneplus.com)
2- Download (from oneplus.com) and install the latest pie *.zip rom package.
- After booting and setting up your phone, try to restore your twrp pie file.
I would recommend to do this after a research "how to downgrade from 10 to 9". So you would have a clear owerview & better understanding.
As always, do a backup first.
