Hi, I have upgraded to Android 7.0 on my Honor 8 yesterday and since then the battery is draining at an insane pace.
I used to get an overnight standby drain of 3-5% on average with 6.0 and it is well over 25% with 7.0. Something called "Android System" has consumed a disproportionate majority of the battery. A similar problem is reported here: https://forum.xda-developers.com/honor-8/help/battery-dropped-40-nougat-honor-8-t3558197
The background app settings haven't been changed -- have about same 6-7 apps like Whatsapp, Outlook, etc. However, when I open the current background apps, I see a few unprotected apps (like Maps) also running in the background. Is this a bug?
Please help out, if there are any fixes.
Thanks.
try apps like greenify to fix wakelocks

Many users are dealing with this problem and I've reported before.. This update is broke, and shouldn't have been pushed officially. There are a lot of bugs, and the most irritating one is the battery consumption.
And I don't think Honor is going to fix any of it since we're used to them not caring about what we deal with.
My personal experience with the Nougat update was that battery drained quicker than usual for the first few days, then it stabilized to normal levels (i.e. more or less what it had been in Marshmallow). I was expecting this behaviour, since system upgrade clears out battery optimization data, and it takes a couple of days for the OS to learn what to optimize. Also I suggest you recheck your battery saving settings (Both the Huawei version under Battery settings and the Google version under Applications).
And since someone is going to ask anyway: no, I haven't done factory reset. There was no need.
But this was just my personal experience with nougat. It's of course quite possible that for some people there is a real constant battery drain (wouldn't be the first time, I had a similar experience with my old Motorola when I upgraded to Lollipop a couple of years ago).
It's not the update. From my experience, I had this issue since I bought the phone. I would factory reset it all the time and this issue would persist.
It turns out that in my case, I would always turn off LTE and use WCDMA instead. My logic being that WCDMA uses less power, so therefore I would get better battery life. Nope. There's a glitch that happens if you do this and have wifi on, It doesn't let the phone go into deep sleep. Ever. So your battery drains about 20℅ overnight.
The solution for me was to simply leave LTE on, and now my battery consumes like 1℅ overnight.
For those suffering from battery drain, check your consumption and see if Google calendar sync is taking up a lot of it.
I had that issue, and had to manually kill the sync (from the accounts screen).
It seems to be an issue on all Huawei devices on 7.0, the native calendar isn't playing well with sync, and unless you're rooted and can uninstall it, you're stuck. (I'm waiting to root until a patch comes out for all these issues first)
All in all, if this is how Huawei treats their devices, and their customers, I won't buy another one of their devices.
I updated via Charles method, but my mother's L04 still hasn't gotten the update. And probably never will unless I do it manually.
Very disappointing.

Thanks. I was thinking of waiting for a couple of days too. Its just been 12 hours and the battery is almost down to 25% from 100%. If it doesn't improve in the next few days, I'll revert to 6.0 with which I had solid 1.5 days battery life for my usage level.
On my frd 09 i got a update after the nougat update which fixed my battery drain it was around 356 mb big. But since maybe 1-2 weeks already. And my battery drain is lower as on MM
I do feel Nougat on my L14 is draining faster than MM. It's mostly Android System or Android OS so I have no idea what is within that taking the power. There is also a weird bug with LTE enabled when I make a call to another cell phone. Most of the time, my phone says it's ringing on the other side but there's no "ringing" sound on my side. Weird. Turn off LTE and you can hear the ringing.
It is always hard to determine what is going on in these sort of circumstances. For me, EMUI 5 doesn't seem to have badly affected my battery life. I just got almost 3.75 hours SOT using Waze for navigation, and still have about 30% battery. According to the detailed power info, Waze was using 1340.27 mAh.

Just for balance, my experience is more like this one, although I don't think I had to wait days for it to not be a battery drainer. Is everyone in this thread talking about b360? (for whatever variant you have)? I did see this on b320, but have used b360 for about 1-2 months now (Charles) and haven't had any noticeable difference in battery life from Marshmallow. It drains 1-3% / night. Screen on time , say browsing is pretty regularly 5.x hours, and typically I get 2-3 days out of a charge.
I believe everyone that says they've got a problem, but I guess some of us got lucky. Just so it's known: Mine is a US L04*b360 variant.
Note: Just as a possible point of difference. Before I was on b360, I had the phone rooted, with TWRP, and had to wipe the entire thing , rollback to b160 and use Charles to get b360. I never did a reset and I don't turn off functionality. Also, maybe most important. I don't use social media hardly at all. I haven't got Facebook or Twitter installed because I don't like either.
i would suggest a factory reset, then install only essential apps and test it for a couple of days.
L04 here, OTA updated and I'm seeing better battery performance than MM.

Try going into settings, accounts, google.
Look to see if anything looks like its stuck syncing. If there is, turn that off. Go into the app that was stuck, and swype down to cause it to refresh, then go back into the setting and turn that syncing back on (if you want it to sync).
Does root and Greenify help?
I contacted Honor Support and reported the problem.
I was suggested to "Wipe Cache Partition". It helped a bit but the battery was still draining at a faster rate than 6.0. So I have now been wiping cache partition on a daily basis after a full charge.
I know it doesn't make much sense but it helps contain the drain a bit, at least when connected to the Internet via WiFi. The drain rate remains the same as soon as I switch to LTE (about 2-3% drain per hour with roughly 5-10 minutes SoT).

My phone wasn't rooted. I'd have tried Greenify but it wasn't any app causing the drain; "Android System" is the culprit. I don't know if Greenify could help with that.

Thanks for your comment. My model number is: FRD-L14 and the build number is B360.
Honor Support recommended to "Wipe Cache Partition". I did that without much luck. I have now been wiping the cache partition after every full charge (which is a ridiculous thing to do!). It does help arrest the drain a bit but only on WiFi. As soon as I turn on the Mobile Data, the battery drains at insane speed (about 2-3% an hour with just 5-10 minutes of SoT).
Hi,
Firmware Finder shows b585 for my phone (L29C636 dual sim), although system update doesn't show it.
3 files downloaded 1.updated 1.3 GB, 2.update data full public 425mb and 3.update full L29 442mb
How to flash it.
Is this firmware safe?
I will download it but not flashing with twrp or dload ... Anyone flash it?
Mate 8, L29C636B585. Noticing a larger than normal battery drain on the Nougat version of Huawei's EMUI. Not sure if this is and issue for Google or Huawei. I already uninstalled apps that I have constantly monitored to be BIG drainers. and I also tried to tweak mobile data access and many more to see which app is really killing my phone. Been at it for 3 weeks now, still on the hunt.
Anyone have a similar experience on their Mate 8? L29C636B858 variant.

On B585 now, I only get about 5-6 hours screen on time and barely get through one day with medium-high usage.

K. my bad. I see it to be as L29C636B585?
I'm retesting.
I got mine from FF because I noticed that L29C636B563 was experiencing the same issue I am having today 4-5 weeks after the update (Official OTA from Huawei) arrived on my phone.
My issues probably started the week of 10 June to 18 June, well after I've had L29C636B563...
The following apps may or will rise up to the top of the list of battery suckers and they happen at random most of the time, mostly too just after taking the phone out from the charging state:
Google Play Services
Calendar
Chrome
Gmail
And other essential apps....
I'll have good battery and see that I still have 30% left, then after 30 minutes at the dinner table... I'd be surprised that my phone suddenly died. This is around 11pm at night.
Anyway, I decided to install L29C636B585 (v84268 FullOTA-MF). I think something went wrong with this firmware update because I did not experience the 9 or 10 MFs that was more apparent in (v84265 OTA-MF).
This was just last Monday I think. First install, my battery was still draining crazily. After the first update to L29C636B585 (v84268 FullOTA-MF). I just restored everything from my Google Account. I did this twice.
A few days ago, I decided to do a full clean install so I processed my third wipe but this time, I started clean. Nope. Something is wrong here! Battery is still draining like CRAZY!
So. around Wednesday this week. I wonder what L29C636B585 (v84265 OTA-MF) is all about. Each package downloaded is less tha 600MB, and after the 9th or 10th prompt, the total MF package size came to 4.5GB and it installed.
After that, I just rebooted.
I noticed that a lot of times (just a 2 day period here), the battery usage would start to steady itself after an initial drain my Google Play Services or some crazy system app. No, it is not an app I installed. Maybe an app that Google Updated like Google Play Service or the Google App (with the Google Assistant).
Prior to updating to Nougat 7.0, I was happy at L29C636B321, the best most stable EMUI for my Mate 8 yet.
Why does Google release Beta Software to unknowing Beta Testers??!?
Yesterday from 4pm to 10:20pm, my battery went from 77% to 62%, that's pretty low usage??! I was also up and about that time. What happened? That's 15% drain in 6 hrs and 20 mins. The battery drain is still not consistent. Not as consistent as my L29C636B321.
That one would have a steady drain, averaging between 3% to 4% on moderate use.
So now... what?? I just installed Doze (for android) again and maybe it will force Google Play Services to doze once in a while since that essential service is exempt from any battery power saving mode.
Uhm :cyclops:

Yes, mine is L29C636B585. While the 5-6 hours screen on time I get seemed low for this phone (could be normal battery wear?), I did not experience the crazy screen-off drain you reported. My battery usage list seem normal with android system being the biggest juice sucker.
Very unhappy with Nougat 7.0 (EMUI 5.0) L29C636B563 and L29C636B585, both are BUGGED to death. The biggest being the BATTERY DRAIN
I wonder if these 2 posts have any bearing at all:

Basically remove (make Not Allowed):
GeofenceService
HwLBSService
In "Ignore Battery Optimization".
Wonder what these 2 services are for? What happens if you remove them from Battery Optimization, i.e., allow them to be optimized.
I bought my Pixel in Nov 2016. Battery lasted on average about 1 day & 10-20 minutes based on my personal usage. In the last few weeks, it barely lasts 24 hours. I haven't added any new apps. My battery usage info doesn't show anything unusual or an app consuming a lot of battery. I downloaded GSam Battery Monitor but that doesn't give details on app usage unless you are rooted which I am not.
Have others also experienced poor battery although the phone is not even a year old?
Any ideas on what it can be? I haven't changed my usage either (I only monitor it on weekdays since that usage is basically the same each day).
Just an example here: took off charger 52 mins ago and it's already at 89%.

What software are you running? If you don't get the OTA for 8.0, I'd enroll in the Beta. This will prompt you to get the official release at this time. Once that's installed, I'd Factory Reset data and start from scratch.
Alternatively, you can uninstall apps one by one to see if there's an increase in performance/battery life. Also, maybe try wiping cache to see if that helps.
Yes mine went from 5-6 hours SOT to maybe 3 1/2 to 4. Horrible. I've flashed countless factory images. Never abkr to figure it out.
I wouldn't expect it's related to the age of the device necessarily. I only just got my Pixel a few weeks ago and it averages about 4 hours SOT over 24 hours with little left in the tank. It's got a small battery.
Mine is terrible on Oreo
You have to give the software about 2-3 days to learn your usage so that it can set everything for you, if you just installed Android Oreo, then, it's going to be at least a day or two before your battery corrects it self.
I have been on the Oreo dev preview, back to Nougat, now back on Oreo and the battery life just has gotten to be terrible. Factory wipes every time I load a new version on Android.
I get about 1.5 to 2 hrs SoT in a 12 hour period and it just about is dead. I have surrendered to the fact that I will just never had good battery life as long as I own an Android phone and I charge them any chance I get.

Personally I use Wakelock Detector on a rooted phone, but it may be possible to get information without root using ADB.

The Wakelock Detector instructions for not having root are more thorough.

I am still on Android 7.1.2 running the latest update - NHG47Q (I think this is the latest). I have not tried the Oreo beta but would hope the battery life will improve since that is one of the new features.
I have heard that one should factory reset when going to a major update like 8.0. I just hate to reinstall everything (apps & settings) from scratch. (I am not rooted.)

Shouldn't have to do that... I've never bothered and it's not caused me any issues. I think people who suggest you do that are probably the same ones who suggest you wipe cache and dalvik cache all the time (burn).
The screen takes an awful lot of battery on this device.
My battery life was getting worse, and a factory reset a few days all fixed it.

My battery drains really fast after I upgraded to Oreo 8.1. 30 minutes of Youtube used up 20% of my battery. It used to be only 10%.
I am,went from 5.5 on nougat to 4 on Oreo to 5 again on 8.1 dp1 and back to 4 on final.....sot of course. No change in usage
try getting rid of Back up to Google Drive took my SOT from 2hrs to 5 very odd
Hi All--
I've been on the Android P Beta for a while.
However, starting with the final beta that was released (and now on the final version of pie) I've been experiencing really quick battery drain.
Tried a total wipe and restore, and the same thing. My wife (also the pixel) isn't having those issues at all.
Thoughts?
(nothing shows up in the battery section)
Yes, I had great battery life. Then once Android Pie was released, jumped on the beta to get 9 sooner. Then got the upgrade from beta to final and battery life is horrible. I did not factory reset, I have battery saver on and it doesn'tseem to matter. If I leave on standby, no issues. If I use the phone, it can bleed as much as 10% per hour! Unacceptable. I may try factory resetting, but idk...
have you allocated sufficient time for app battery optimization?
I also have a pixel, Android 9.0/Pie (bought it brand new three days ago) and think battery is draining very (!) quick.
Yesterday I had roughly 2.5 SOT (with battery saver enabled) and this seems consistent with what I can expect typically. I did factory reset and have tried restricting "background activity" for my frequent apps - seems to make no difference. Obviously it had not time to do full battery optimization yet I guess, but I doubt it would mean a that big difference?
Saw a thread where someone mentioned it seems CPU-freq is high/inc. very rapidly when just tapping the screen (GPU-0%), and I can agree with that although I have not the prev. experience of what to expect.
My previous experience is with Xiaomi mi6/mi5 (lineage 15.1), similar usage would give 2x or 3x SOT (however with some other hw-issues.. ).

Flashed factory image without -w/"wipe". Will that do or should it be "full" factory reset to make sense?
Thank you for your information, I will stay on Oreo.

I don't think it would make a difference. The user data is on a different partition.
You could try flashing the image again, without Magisk or any other additions.
I had used up 50% with only 21 minutes screen on time.
I noticed the app Device Health Services, was constantly active in the background.
I had the same like the OP: everything was fine until the last beta came, and battery is draining faster, phone gets hot from even the smallest usage even in the prod release of android pie.
I was thinking it has something to do with being about 36 degrees (summer time....), but it is the same even in cooler temperature rooms. It's like if the phone is constantly doing something in the background, but only if I use it.
It has been a few days since I upgraded my Pixel 2. Battery life is noticably worse, maybe 20-30% more battery drain in a day than what I saw in Oreo.
I notice the issue as well. I did factory reset after update it's been a week. I was on beta and started noticing battery issues in the first beta and throughout. I decided to install Accubattery to track my battery usage and ended up with a result.
My phone states the battery is in good condition but this app says otherwise. I guess it's time to change the battery along with cracked screen!
i'm curious if my battery is shot as well... Seems like after I purchased my used Pixel.. the battery is not as lasting as I hoped for the smaller pixel phone... I may try one of those battery testing apps to see if it will tell me its current health..
I normally welcome up updates, but this update screwed up my battery life so bad. I mean everything was perfect until the update. Now the battery drains so fast I can watch the percentage count down like a timer and now when the battery gets anywhere from 15-40% the phone will just shut down.
I would like to go back to oreo, but it's such a pain in the ass having to back everything up and flash a ROM considering I haven't done that since before I bought the pixel
I have the same problem. I hope Google can fix it.
Wow, that is not normal. Stock android 9 with root and elemental kernel.... I go back to android 8.1.0 and wait for feature releases
I think I found an Draining App/Setting
I disable the RCS Service on my Phone. It can be found under Messages >> 3 dot Menu >> Settings >> broadcast News. Disable it.
And then Bluetooth and WiFi scan disable.
Same here, crazy idle drain after pie, only 50% deep sleep, tried factory reset and no luck
Try BetterBatteryStats. People in that thread spend their free time analyzing logs to tell you what's eating up all your battery life.

Same problem :crying::crying:
I'm not even kidding. Everything was perfect and I had absolutely no problems until they sent out that update. Now I can watch my battery percentage dropping by the second and my phone will shut off around 30%.
Once again, I had no problems until the August update. I never even rooted this phone, so the last thing I want to do is to figure that out to downgrade to the last version. I will if I have to though
If your phone spontaneously shuts down with the battery at 30%, then I see 2 possibilities:
It's overheating, or
The battery has reached end-of-life
Use an app to determine the remaining capacity of your battery (usually displayed in mAh). The results of such apps should be taken with a grain of salt, but if it says your battery is only at 60 or 70% of original capacity, then it's definitely not normal.

I'm not even kidding. Everything was perfect and I had absolutely no problems until they sent out that update. Now I can watch my battery percentage dropping by the second and my phone will shut off around 30%.
Once again, I had no problems until the August update. I never even rooted this phone, so the last thing I want to do is to figure that out to downgrade to the last version. I will if I have to though

You could try to go to recovery, wipe cache and reboot. Or, if possible, wait for the next security update and see if it gets fixed if you have a spare phone to use. These are the only two opportunities without messing around or loosing data.
A downgrade always needs a full data wipe AFAIK. If you aren't afraid of data loss, you could try a full factory reset and see if the battery drain is gone.
I noticed the same on my Pixel - i don't use it a great deal and was seeing 6 days before it'd drop to 30 to 35% battery level, now i'm seeing 2.5 to 3 days - my usage has not changed
I really don't think it's battery nearing end of life - the phone & battery are just now hitting the 2 yr mark

I don't think it's end of life either. Like I said, everything was great until the update. My GF got the same phone around the same time and I told her not to update. So she's still running the last version and her phone is still perfect.
Is the battery life still abysmal when running in safe mode? if so, it may be a rogue 3rd party app.
my battery life was crap with the kernel and android system after i updated to August as well. I assumed it was a Magisk update or module that was the issue. Once I moved to Android Pie my battery life has returned.

I haven't tried safe mode - my battery was surprising decent under Android 8. the day it updated to Android 9 it went south in a handbasket. And i noticed "battery saver" selection is no longer available
i'm trying to read up and re-learn installing a custom rom, and which rom to choose - i last did a custom rom in 2010 and haven't been near the forums since then, but this issue and the more i learn about google's surveillance collection, i want to go custom
Since you're willing to install a custom ROM, why not try to reinstall the full stock ROM first?
appreciate the suggestion - that's what i originally wanted to do and posted here a few weeks back asking how to revert to android 8 and was told it couldn't be done but i could do a custom rom
and now, with the privacy issues i've been reading about, i think i'd prefer to limit my services as googles' "product". It kind of alarmed me how sensitive the phone's microphone was - i actually wrapped the phone in a heavy towel and left it 5 feet away, and said "OK google" in a normal voice - and bam, it was opened when i unwrapped the phone. There's no reason for the microphone to be that sensitive, imho
but i'm an old fart, and the younger generations don't seem to relish their privacy like i do - that's fine for them, no judgment on my part, i just like my privacy
