The 15a update was described as a security patch. I can't be sure but it seems to have improved my idle battery drain. I have seen a noticeable improvement in battery life since the update.
The only problem I have in assessing this is that a bunch of my apps updated around the same time. However, battery usage no longer shows Andorid OS as the chief consumer of battery. Anyone else have this experience?
I have noticed it too.
I noticed the same thing but at the same time I dont think much of it because you cant stop the android OS without crashing your entire phone. But one issue that really pisses me off is when the update came it corrupted my MicroSD card and made it unusable, like as in even if I format it it wont work/wont format even with my computer because I lost a lot of pictures off of that as well as other important things.
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).
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.

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
Has anyone been able to remedy battery drain after March and June OTA updates? Any method to revert back to earlier firmware, I tried and got slapped with "binary 10 > 8 error." Has anyone had success with FDR? Safemode has no effect so far.
Admittedly I was a sleep at the wheel with this issue I allowed OTA update to G90UUESACSF1. After update, my battery life is about half. Can watch it drop while browsing. Been up for about an hour now and down 13% from a full charge under minor use. To boot, all of the progs listed "battery use" don't account for 30% of total use so far. Ahhh, good ole planned obsolescence.
Thanks in advance.

The only thing I could think of is re seating the battery.
But you would have to take apart the phone to do that

I repair these S7's daily, and it's not necessarily the firmware update but the age of the battery causing the quicker drain. Since they are about 4 years old now, the chemicals inside the cells has started to deteriorate, therefore the only solution is to replace it with a good quality battery (not a cheap $5 Ebay bootleg ones, but a $20 original!)
Anyone experiencing poor battery life after this latest patch?
My mobile network battery is very high and I'm on wifi.
Ideas?
The latest patch as in the one that released today? If so, high usage is normal for a few days. If it's the update from last month, you might consider a factory reset and setting all your apps up from scratch. Time consuming for sure but gives you a clean slate with the battery.

I concur with this assuming you're on the May update which only just was released. I'd be patient and report back after a few days at least.

I just updated to the April patch due to a rooting error and reinstalled from scratch. Phone was fine prior to that.
Guess I'll just update to the newest one and see what happens? The strange thing is the high mobile network battery usage

Yep, this is what I see too, I posted the pics in another forum and got a number of "that's odd" comments, where my overnight drain due to the mobile radio was crazy-high (this happened back in the Nov timeframe, fixed with the Jan update, and started again with March, pretty consistent, for me).
I typically charge in the AM, wirelessly, while I catch up on emails and such, so the phone had light use all day, and the bulk of the discharge was from 12A until around 9A, when it was not in-use.
We're located in a suburban area with very strong LTE and decent 5G towers all nearby, with (almost) always very low (e.g. "good") dBM signal values, for the mobile radio.
I flashed the April update as soon as it was released. I have also noticed that my battery life has been a bit worse on the April update.
Furthermore, I also root my phone. However, I always do a full wipe and fresh install with each update. So, I can confirm that there does indeed seem to be a potential battery drain issue on the April build. And as you have stated, I believe that it has something to do with the mobile data scanning. However, when I stay connected to WiFi, my battery doesn't drain as quickly as it does when I turn WiFi off.
Regardless, the May update has released today and so I'll likely be updating to that tonight to see whether or not this faster battery drain issue continues.
*Edit* - The May update - although only running on my device for around 12 hours - does seem to have improved that battery drain issue that was visible on the April factory image. However, this mobile data battery issue could very well be a result of Google pushing out all of these carrier service updates. Of which, they are presumably doing so in order to test the stock OS setup for their two new devices that will be launching within the next month: the Pixel 7A and the Pixel Phold. Therefore, if carrier service testing was the culprit of this issue, then I wouldn't be surprised if we see this issue pop up again due to further mobile data stability/reliability testing.
*Edit 2* - May update was installed for a few days. My battery life is MUCH better. It is essentially how it was prior to the April update.

Did you find any fixes? i updated to the May build and the issue is even WORSE. Phone idle for last two hours after full charge, down 12% already from mobile wifi data. Its literally sitting screen off burning 6% per hour
four hours of on time after full charge. 15% battery discharge - done by mobile network....ive been on wifi the whole time.
what gives?

On the AndroidCentral forums a user referenced an actual Google support thread (which had been locked, interestingly), where they had supposedly been told, by support, to revert to 3G.
That's sort of tough to believe though, if you ask me, given the fact most carriers in Google's largest Pixel market sun-setted 3G some time ago (my carrier, TMo, did it last summer, not that I cared much, but I was tracking things).
I'd say they might have confused 3G/4G-LTE, except that they specifically called out moving from 5G/4G-LTE -> 3G, weird, eh?

I would bet this is because the algorithmic calculation is done based on carrier-type use, which would involve pretty much any interrupts regarding phone/sms/rcs.
My guess anyway, I tried this too, one night, and saw a similar deal.
Whatever the cause may be, it's software related and it's very aggravating. Phone was fine a few days ago
I had the same problem with the April update. due to a change of contract i now only have lte, no more 5g. Since then the battery has held up like it used to.
I have to wonder what some people are doing to make their phones...or batteries...so awful?
I have the latest May, 2023 update installed. I happened to sideload the OTA instead of waiting but I do not think that makes any difference in the end. However, the very first thing I noticed was that everything seemed a little smoother??? (placebo effect??)
The very next thing I noticed was battery life...mine improved exponentially and it wasn't bad before the update!
For example I removed the phone off of the Google wireless charger around 5 AM, then I used it on Android Auto for a round trip of about 33 miles, and when I got home (four hours off the charger) I was STILL AT 100% Hand-of-God!
When I went to bed around 9:30 PM (yes, I'm getting old) the phone was at 90%...honest to GOD again!
Looked at the battery again around 6 AM and it was at 85%. The phone was on all night with DND activated, but everything else active.
I can only guess that one of two things are happening here...either some of you have installed crap-apps that have hosed your phones, or.....you have defective phones/batteries.
YMMV
I haven't noticed much of a change with the battery after applying the March update, purposely left the phone off the changer overnight with battery at 100% (12am) - looked at the phone at 6am and percentage was down to 97%.

did you read the post or just decide it was user error b/c your battery life is fine right now?
There were multiple pictures posted of the mobile network battery drain which has been documented elsewhere and confirmed by another user in the thread.
Battery life was great until the April update then the mobile network drain started which hasn't been corrected by multiple updates and full wipes.
