Huge battery drain problem after Lilipop update

After updating my Z3's firmware to Lilipop, I'm facing huge battery drain. In kitkat, when returning home battery remained 55%. After update, I found it 30-35%. Note that my usage pattern didn't change.
How can I get rid of it?

There is another thread for this issue.

Does there have the solution? Please share the link.

Many users reported that a factory reset fixed their problems. Only downside is that you have to reconfigure your phone

done factory reset manytimes but the drain remains..
seems like radio being active by apps is the problem
i'd love to post screenshots but since i am new here you know i am unable

Have you tried using BBS (better battery stats) to isolate the drain? And also try setting "keep wifi in sleepmode" to never or only when connected. Have heard of that working wonders for some.
And the screenshot thing can be overcome by uploading it to a different site and posting only the links

Preper yourself for NO notifications, if you put WI-FI to sleep.

I have wifi asleep and still get notifications. Maybe a little less frequent, but that's because stamina mode is working better (in my opinion) and only checks once in a while for new notifications

That' s the Queue background data option that is doing that.

So there ARE notifications Vs what you said that there would be none. I rest my case here

MOD EDIT @gregbradley
@ OP, I also ticked the option that other apps may not use wifi for location even when wifi is off. I believe that may also cost you some juice

thanks for suggestions ..

It's funny how my phone ran normal for the first week now the phone is being drained by Facebook and feedly, I have made no changes in any settings and its happening now. Haven't looked into the problem yet but don't even know is it third party issues lol.
One thing I found out is that the battery tend to drain at a lesser rate if you leave the phone charged for an extra 20 mins or more after hitting 100%. Just a speculation

So, blame facebook for the battery drain.
There is an option where you can make the phone play a sound when is fully charged.

.

Just clean flash stock ftf.. Ota just sucks. I did it and my battery returned to prime life again.

.

I doubt that the reason we have the same problem is the same, but since I know how to post a screen cap, here's mine:

.

Why do I have terrible battery life?

I just got my Z5 a few days ago, and the battery life is downright AWFUL. With stamina mode on, my phone drains about 1% every minute or two, just while browsing the web. What is going on here?
Here's a screenshot: http://i.imgur.com/uDv2hIs.png

Me too, it's a total letdown. Had 3 hours SOC and around 9-10 hours overall before it conked out on me yesterday

Looks like your device is spending a lot of time switching networks which is battery intensive. Are you in a poor signal area?

Occasionally, but not all the time. The battery drain was still this bad even when I was connected to my WiFi signal at home

Try airplane mode and see if it improves. This will allow you to use WIFI but halt network search and switching. Check battery stats after a while to see if that helps. Of course, you will get no network dependent communications while in airplane mode so take that into consideration prior to testing. Battery performance will settle down after a few weeks as well but you certainly seem to have a major drain problem and testing will help you locate the cause.

All right, thanks. I'm gonna try that and report back here later today.

Okay, airplane mode hasn't helped much at all. I'm still draining 1% every minute or two.

That is truly strange. Any running apps killing it? I just streamed a two hour movie and lost 22%. I read somewhere that the pre-installed AVG was a battery hog. I couldn't tell you because I uninstalled it as soon as I booted for the first time. Are you still running it? That may be the next test.

Nope, I uninstalled it immediately too.

Only other suggestion is factory reset or repair firmware both if which are a PIA.

Have you looked at your Google account settings to see if everything is syncing properly? I have seen this before when someone had an error while trying to sync photos to their Google account, demolished their battery until they went into account settings and unchecked whatever it was that was syncing constantly.
Also make sure you have opted out of Google's location history thing in Google maps where it tells you everywhere you've been on any given day, that can wipe your battery as well. Lastly try turning off the xperia protection that allows you to remotely deactivate the phone, just make sure you don't lose it in the meantime !

I got a Z5 the day it came out and it has done pretty well on battery life, at least until I installed Facebook and Messenger. When I uninstalled the two of them, the battery life returned to pretty good. With Facebook and Messenger the battery was draining extremely quickly. I unlocked the bootloader the day I got the phone and am waiting for TWRP as root will sort a lot of this out.

After 3 Days, i looks like a normale Day use by me around 50% battery. I have allthetime Bluetooth and Wlan on. Whatsapp and Gmail sync. I use my Phone usually for streamming musik over bluetooth around 2h hours, read news and message (Whatsapp) around 2h hours, play some games around 30minutes and some Calls around the same time. My "old" Z1 i had usually to charge ones during the day and of course during the night. So im happy with the battery time @ z5.

Okay, I just turned off automatic Google photos backup, and Google's location history setting was already off. I also turned off my Xperia (the thing that lets me remotely deactivate the phone). Let's see if it works.

Yeah, its still draining fast. In case you're wondering, I keep my screen at half brightness. You can look at the photo I attached.

Update?
Did you ever resolve the issue? I'm getting similar battery life and am not happy about it.

This may be a noob-ish suggestion and one that the phone industry claims isn't necessary anymore, but have you tried "calibrating" the battery by charging it to 100 and completely draining it to the point where the phone won't turn on 2 times and then fully charging it a 3rd time? It may be an old, unnecessary habit, but I've done this every time I get a new battery (or phone) and I usually have really good battery life for the first year - year and a half. The one device I failed to do this on was my Xperia z2 tablet and it suffered for it (i think) although that could just be my prejudice and confirmation bias speaking.

- others suggest NOT to fully drain your phone's battery because you might have troubles turning it on.

Did you by any chance have "Glove Mode" enabled in Settings < Display? It seems that your screen is the culprit. Try disabling "Smart backlight" if you have it enabled and "Tap to wake up".
From the screenshot you posted earlier (History details) we can see that even when the screen is off the wifi is on and the phone isn't actually sleeping. So you got a wakelock on your hands that uses WiFi and doesn't let the phone sleep.
In WiFi settings under advanced (Wifi< Three dots, top right< Advanced) do you have wifi as always on? Change it to "Only when plugged in", also disable "Scanning always available" in the same menu.
Any chance we can get a list of apps you have installed yourself on your phone?

Has there been any fixes to the battery drain issues with 7.0 update on Honor 8 (US)?

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).

Battery Drain (Pixel 4a Global)

I reformatted to factory settings, and even reinstalled all factory images. I still get a lot of battery drain daily. the battery details screenshot indicates that Google is always on and Suspend Wakelock is always on. what can I do to fix this issue? I am unable to keep this phone otherwise. I always have battery drain issues on Android yet seems as though Google has not provided a stable fix...
I cant get even one hour of screentime on Android until it hits 80%.
I just need to know how to fix the Wakelock issue because I think that's what it is. I tried Wakelock apps but they don't do anything.
EDIT: resolved. just reflashed using Android Flash Tool and that corrected it.

Oy Vey. Battery life (power consumption) is outstanding on this device right out of the box. No rogue wakelocks here. Misbehaving apps and panel brightness are the two biggest drainers. Adjust your life and so called "SOT" will improve. Note the battery is 'only' ~3140 mAh. Don't expect all day longevity if gaming or in constant use. That's not what this phone is about.

I was able to resolve the issue by reflashing. I had used BBS hence why the suspendlockout at 100%.
Steps to resolve. (aware that this may not be the most ideal option for some)
- Reflash using the Android Flash Tool (don't manually update, just use the flash tool provided by Google)
- Start from scratch. Do not restore from backup. Install most needed apps.
- Observe battery drain over the course of the day
The issue was that Google app (not sure which app that is) did not run in background properly hence the high drain.
I was able to get 6 hours of SOT once I reflashed. Here is to hoping 7 hours of SOT with a modified kernel.

Kernel appears well optimized on this device; doubt you will see significant power utilization improvements with custom varients. More likely to score headaches w/o a corresponding benefit.

I'm on my second cycle. Got close to 9 hrs sot on first. Here's my 2nd after useing it for an hour this morning. Even better than my OP5T! I use wifi almost all the time since I don't get any cell bars at home.

Yep - especially if signal is weak/marginal forcing the mobile radio to maintain a higher power level. Same thing can happen on WiFi although have more options to cycle WiFi on/off during screen off operations. In contrast, mobile radio is on 7x24 unless you tell it otherwise.

Ok thanks. I’ll test it out soon on wifi and see what happens.
I saw that the Pixel 5 is about the same form size as the 4a but with the larger battery. Out of curiosity, anyone know if it’s possible to jam that 4,000mah battery inside the 4a? I haven’t seen the internals so don’t know if there’s enough room.

Help : Fast battery drainage

Did anyone encounter the same problem??
Two 5ii of mine are draining too fast this month.
I don't think it's a hardware problem, but a software problem.
Anyone??

I noticed that too for a week.
It must have been some Google service update that generated a lot of unusual wakelocks.
In my case, it's gone and back to normal.
reboot your device just in case

Same here as I texted this. I've getting SOT like less than 4 hours per day even I've restricted battery on some apps and restricting background data. However the issue still persists.
Kinda agree with the Google Service Update thingy since after some play store or updates installed and the battery drainage is just absurd.
Also throttling the CPU a lot and temperature is higher than usual, almost achieving 40°C in just usual social media, browsing and working.
Worst is that I've reboot in safe mode, and multiple restarts and is still draining battery vigorously.
Hope some software or google updates can solve this issue quickly.

From my experience (see my previous post) i had the problem for about 1 week and then it went away.
And lately, I'm getting the best-ever deep sleep battery consumption during night: ~3% .
I did not tweak any app battery policy in settings and I'm using stock A12 latest update.
You may have some rogue app update that is not in tune with the correct power management posture.

I have the same issue. It seems to have been triggered by poor network connectivity or something. The first time I had this issue, I had to solve it via software repair. I'm not keen to go through the process for the second time. I have shut down and restarted my phone several times.

There have been a number of posts on Reddit recently about massive battery drain with Sony phones.
Here and here and here and here
Seems like it's a Sony Vs Google problem
I have had the same huge battery drain, with my phone going from lasting two days between charges, to now getting hot and lasting just 15 hours
When I look at running apps, I see Gooogle Play Services has 2 or 3 instancnces. Some with 13 services. In the last two weeks Play Services has used 825Mb of data. Feels like my phone has become an AV transmitter.

Hello guys, today I noticed that the battery is finally back to normal. I turned on auto-update for everything and let it update whatever it needs to at the very first place.
Hope this kind of **** don't happen ever again.

I don't have auto-update and that issue only lasted a few days
