[Q] Play Services crazy battery drain on brand new installation

I was having a few battery drain and stability problems so I decided it was time to do a fresh install of Android. The main culprit was Play Services but it was always a different thread and I could never get the problem under control. I was barely getting through a 16 hour day on a single battery charge even with only an hour of screen on time which is insane for these droid maxx's.
I flashed stock Android 4.4 and accidentally unrooted myself in the process, but that means I am 100% stock kitkat with the late April mini update.
I still have the Play Services battery drain bug.
I killed half my battery yesterday in like a half hour of screen on time and 7 hours of idle. The phone won't sleep. Google Play Services still shows as the culprit in the battery settings.
I've disabled Now, location settings, sync (it literally doesn't sync anything), wi-fi, and interest-based ads. (All tips I've seen from people that have had the bug across XDA). I've let Play Services update from 4.8 to 5.0. And it still won't let the phone go to sleep.
Anyone have any other thoughts on the issue? I'm ready to pull my hair out! I have no idea what's causing this bug but it's driving me up the wall.
BTW I don't have any meaningful screenshots right now because I'm not rooted yet. I'm going to try jcase's pie method to get root back and post via BBS, but in the meantime I've heard this is a fairly common issue, so I threw the post up in case anyone else has encountered and solved the problem. What I'll share in the meantime is that my phone has been off the charger today for 1 hr 39 min. Play Services has kept it awake for 1 hr 38 min.

Ive had this problem too... Only I am on 4.2.2. Only fix for me was either nandroid'ing back to a previous state [temporary fix] or using Xposed + WakeLock Terminator to prevent GPS from getting WakeLock [So far has been permanent for about 1 month]

There's a couple of ways to address this. As noted, this is an issue with the play services abusing the GPS. In addition, it's a problem with the stock firmware. As I am sure you want to continue using GPS, these options allow you to leave it on.
In the GPS configuration, it's possible to reduce or turn off access to GPS to individual apps.
There are apps that allow managing app permissions. You can use this to revoke access to various things. Use it to revoke play services access to GPS.
If memory serves me right, these don't require root.

I managed to get root back so what I'm experimenting with is the app ops settings. I'll report back with an update. Thanks for the ideas guys.

Battery Drain, still after trying some fixes

Hello xda,
I have my Oneplus One more than one year now, and the geatest thing I alwasy notices was the much better Battery life.
I dont know what happened, but before 2 weeks my One needed much more battery when i did nothing with it:
Before 3 weeks: 10 hour in the night, with only 30 min screen on, the One used les than 3% battery.
Since 2 weeks: same 20 hour in the night,less than 30 min screen on, the One needs mor than 13% battery!
So before 1 week i completly wiped my device, flashed an new custom recovery and installed stock COS12.
I had not backed up any apps or settings or restored them, but changed everything new in COS, so that i did not copy any mistakes which i had from before.
The problem remained and i still had battery drain when the devices screen was off.
So i searched in the Web, and installed a battery watch app.
These are the fixes i tried:
-Disable double tap-to-wake
- Uninstall Google Play Services updates and install the new ones from Play Store
- Install an App called Wakelock-Fix, which activates and deactivates one google update service everytime after rebooting you phone.
- Using Privacy Guard and disabeling the wake up and stay active settings from Google Play Services.
After i tried this fixes the battery drain stayed as worse as it was before but instead of the Google Play Services in the Battery Usage only the Google Services showed up!!!
Sorry for my bad English, I am from Germany.
And sorry if there is already a thread or Solution in this forum, but i searched some hours in the Web and did not find anything.
Please ask if something is not clear.
Screenshots willl come later.
Here are some screenshots:
https://drive.google.com/open?id=0B...xHSEJWamFEWDBicTNMYm1QWkZSclRhS2JJVXk2elhVTTg
Look at the date of the pictures to see the development from Google Play Services battery drain to Google Services battery drain. Also i added some Pictures of SetCPU with the Tim in State because before 3 weeks i had more than 90% of the time only 300 MHz but today i have less than 80%.
And i added some Screenshots of each Tab in BetterBatteryStats.

Nothing looks unusual there. Your screenshots from BetterBatteryStats show that in an 11:50:29 period it is as follows:
Screen on = 00:32:57
Device awake = 00:42:04
Deep sleep = 11:08:24
This tells us that your device isn't being held awake when it shouln't be, it's only awake a little over nine minutes more than the screen on time which is actually pretty good. Are you comparing Lollipop to Lollipop or are you comparing Lollipop to KitKat? What I'm seeing here looks pretty normal to me for Lollipop.

The Screenshots were made all within 2 Weeks till now and always based on Lollipop 5.0.2
Is this really normal? Because when i first got the device with KitKat i only lost 2-3% over 10 hours in the night and before some weeks when i had been longer on Lollipop the battery usage suddenly went up.
And the Google Services are still using lots of battery or is this normal? Because I had only Google Play services using the Battery too much and now i have the Google Services instead.
Just saw on Twitter that COS12.1 with Android 5.1.1 will come out, maybe i will just wait for the Update.
But thank you so far.
:good:

So you are essentially comparing Lollipop to KitKat. Lollipop doesn't get as good battery life as KitKat had, so that's part of what you're experiencing. Google Play Services and Google Services are the same thing, it's just showing up differently in your battery stats page. Honestly, I don't think you have anything to worry about, everything in your screenshots looks completely normal to me. Just enjoy your device. Maybe try the latest COS12.1 update or a custom ROM.

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.

Battery life considerably worse after update to 9.0

OTA update to 9.0 available a couple of days ago so I let it install. Since then, I've seen considerably quicker draining of the battery, with my usage of the phone being much the same as before. For example, when I went to sleep last night the battery was at 64%, and there were no apps running according to a swipe up from Home, but when I woke this morning, battery was down to 2%. I normally charge once a day, and previously the battery was hardly ever below 50% after 24 hours - I'm a pretty light user.
As an aside, with 9.0 there no longer appears to be possible under battery usage information in Settings to see the percentage of battery that has been used by the various apps and processes.

Ok here. 62% drop over night doing nothing suggests you have a rogue app in there. I'm assuming you have ok cellular coverage and nothing has changed there by coincidence. I would reboot and force close every app you have that's not essential overnight and try again. Swipe up from home and clearing those apps doesn't force close the apps. Greenify is an app that (in manual mode) will make it easy to select as many apps as you want and force close the lot of them. If that improves the situation you can then begin to work out which app(s) might be doing bad stuff whilst you sleep...

Battery on my P2 has significantly improved with Pie even if I didn't have any major problem with 8.1 either. Overnight drain 3-4%. After regular use after a full day I easily exceed 5h SOT. Everything stock with just Greenify in non root mode. I couldn't be happier, best Android release so far for me.

I've had my p2 installed with PIE for about 2 days now. I suggest giving it a week (which is what I'm doing) and then getting a full overview of how my battery is performing. Usually, after any major OS updates, being that apps are trying to utilize your resources and a new version of Android would try to allocate and learn your usage (in this case battery), you'd get a much better definitive idea of your overall performance.
I also think that since its now available, turn on Adaptive Battery mode. After a day of upgrading the OS, Adaptive battery at my 26 hr mark of upgrade said that one of my apps was taking in a lot of resources to be used in the background (ES File Explorer). I made AB to stop ES from taking battery resources.
So in conclusion, if it a week and then you'll be able to get a better overall understanding of whether your battery REALLY has gotten worse or better.
Hope this helps!

Interestingly, my battery was dropping really quickly too after the update to DP3, I switched off Adaptive Battery and it fixed the issue completely.
I tried it again with Android Pie and the issue resumed, so I turned it back off. Maybe try this too?

Exact same problem here after updating. Even tried a factory reset in case it was an updating issue. Same problem. My battery is currently at 43% 4 hours after a full charge. And I've barely used it. This is really poor.
No new apps installed.
My Oreo battery life was great. I'll try shutting off adaptive battery as suggested - but seems a real shame if one of the flagship battery saving features is doing the total opposite on Google's current flagship phone!
Doesn't seem to be a massively common issue so not sure if a likelihood of a patch either

Just a quick update - Google play services has now become the biggest drain on my battery, just as it was before I factory reset after the first install...
Anyone else had the same?

I had the same issue and did the same thing... until dp3 and my battery usage was terrible again even with adaptive battery turned off. I ended up turning it on again and after about a week my battery usage was back where it was before. So there doesn't seem to be a magic bullet here. FWIW app usage offered no insight as to what was causing the drain in the first place.

THIS.
I got like 8+ hours of SOT.... no mobile network though, all day wifi use only.

I have this issue. Dropped about 40% over night. I found that turning wifi off stopped the drain completely. I did not have this problem with Oreo at all so it's not the networks im connecting to. Weird thing is this did not happen when I first installed Pie. This started happening about 3 days into installing. Also, I put it in safe mode and saw the same drain with wifi on vs off.

Hi guys,
I seem to have fixed my terrible battery life!
The below might be worth a try if you're still suffering from it.
I noticed in GSAM that RCSphone was the front runner in battery drain so did a little research and found this site.
SOLUTION: Turn off app preview messages (settings / google / app preview messages). Apparently its only function is to allow Allo messages to be received without the app. To me, totally pointless as i don't know - nor have ever met - a single person who uses it.
I've gone from draining 8-10% an hour (screen off) to around 2.5%/hour and from 1hr 35 total SOT to 3hrs 39 minutes with 32% left (and an hour of that was Google maps navigating, so a proper work out for the phone).
Do give it a try and let me know if it works for you.
Although there's room for improvement (idle 2.5%/h seems high to me!) and it's ludicrous that I should have spent several hours finding a fix for this on 100% stock android, I'm very happy to have a usable battery life back again...
Adam.
UPDATE: Seems like in the night I lost 40% again. Idle drain climbed it's way up to 5.6% in the night. Still an improvement from where it was before, but not quite as good as it first appeared...

@Burkules I drop 0.4 - 0.7%/hr over night with Bluetooth off/Wifi on/strong cellular signal. Much the same as it was with Oreo. Not quite sure why's there's such a big range (almost 2x) but either way it's ok for me. Did you try the technique above?

Cheers for getting back on this.
I left it on safe mode the other night and it still drained absurdly fast, which suggests to me it's a google system drain rather than rogue app, but will try again with app preview now switched off. Likewise will try greenify again and report back.

Likewise maybe app preview set to off will help me even more. If I recall correctly rogue apps can cause some google system apps to wake up, but perhaps not in safe mode...

So, switched off adaptive battery again (i'd enabled it after my short-lived miracle recovery the other day) and now I'm down to 4%/hour. Which is better but still really high for idling! Cleared cache and data in Google play services for good measure too as it still comes up super high on the list of battery drainers.
Booting into safe mode now to check the drain without adaptive there and will report back...
UPDATE: Exactly the same drain in safe mode. This is a straight up google problem....

Haven't tried this - but if the battery drain is the same in safe mode (with only google/system apps running) I can't see how it will make a difference. Ill be in rehearsal for several hours today so will force close everything and will then be leaving my phone idling for a few hours anyway.
I signup up to the google play services beta yesterday, and google play services no longer appears as one of the top battery users... but the battery drain is the same and the numbers given in *all* battery apps (Gsam/accubattery/system) don't add up to anything close to the actual % drain. System battery displays 15% of usage (with 'full device usage' on show) when the battery is quite evidently at 48% from full charge. Total cluster****. So pissed off I updated.
Have you seen any improvement in yours with any of these workarounds?

Nothing to lose by trying. And as I said, Greenify makes it easy/quick to do. Force closing is almost as good as uninstalling those apps as the vast majority of installed apps won't restart or run in background until you use them for the first time again. In my experience, quiescent battery consumption (e.g. noticed over night):
Is vastly affected negatively by poor cellular signal strength. Marginal coverage can really drain the battery fast.
Gradually gets worse between reboots
Can be improved (once it degrades) if you force close all the apps you've installed, and swipe away the background apps just before you go to bed!
If quiescent consumption suddenly rises I can normally fix it by force closing all the apps (not being sure which was the one gone rogue/suddenly misbehaving)
At night I generally have excellent cellular coverage, good WiFi, and Bluetooth is off. NFC is always off
I don't enable sync on 2 of the 3 Gmail accounts I have configured
I disable notifications from any apps I don't actually need them from
Quiescent battery consumption is between, say, 0.4% and, 0.7%/hr at home, around 2 to 3%/hr when out and about which I put down to all background data being driven over 4G instead of Wifi, and variable cellular coverage
I've not noticed quiescent battery consumption change between Oreo and Pie, but this may be because I keep force closing apps at night and not giving adaptive battery (which I have on) a chance to have the same effect intelligently
Turning off app preview messages has made no practical different for me
I'm completely stock (stock launcher, not rooted, etc.)
If you can't fix it, at least a factory reset as the next experiment has the option to restore *most* of what was there before (so long as you have had the backup setting enabled). But because not everything is restored it's still a pain. And if that doesn't work it's another factory reset and test and then restore everything manually and gradually :-S. But I think you already tried that?

Thanks, just tried that as well and my battery has stayed resolutely at 68% on idle beside me for the last few hours, previously it had gone from 100% down to 69% in about 4 hours whilst similarly doing nothing.

OP7Pro battery drain 10%/h screen off 🤯 HELP

So I've had my OnePlus 7 Pro for over a year now and battery has been getting steadily worse. I've been running the latest stock beta channel (O2_BETA_5 atm) with Magisk and my battery drain has been consistently awful. I'd turn off WiFi in the evening and still my battery would be half gone by the morning. In the beginning the phone would easily last the day and now it barely gets me halfway through. I've attached a SS from AccuBattery showing a 10%/h drain with screen off. I've ordered a new battery but don't see the point of changing it before fixing this glaring software issue. I've done minor tweaks with root (including https://github.com/peterroth/OnePlusBatterySaver) so I don't know - maybe I ****ed something up. I would prefer not to do a factory reset but at this point I don't know what else to try. Please help!

Was also using beta 5, moved too the latest stable. Battery on last beta is bad.
Or maybe install BBS to monitor what's draining your battery

Lot of trash apps.
At least block the Gallery app with Karma Firewall; it doesn't need internet access unless you're using cloud services.
Any cloud services impact battery life...
Google Backup Transport, Framework and Google play Services are known serial offenders.
Google Firebase is another one that runs in the background mining your data like a little b$tch.
Trash apps sometimes wake up Google system apps or Android Services with their bs.
