Hi there!
I just bought four days ago a Note 8 (my 6 month old Pixel XL simply bricked itself) and i found it a pretty nice device.
But one strange thing is happening, maybe you guys can help me pinpoint where the problem is: when I put my device inside my jacket pocket, it goes really hot and battery goes down the drain.
If I remove it from my pocket, it cools down and battery drain comes back to acceptable levels.
My initial conclusion is that something using the proximity sensor is draining the battery... any ideas?
Do you guys recommend any tools that would help detect where the problem is? I don't want to root the device.
I use kin screen to keep the screen on while I am using the phone. I thought it might be the culprit at first, but uninstalling it didn't solve the problem.
I used package disabler pro to disable some bloatware like onedrive, carrier apps and such, no success. Enabled all apps again, same problem.
Any help would be appreciated... thanks in advance!

Not sure what could be draining your battery in your pocket but you may want to try this setting: Settings>Display>Block accidental touches (prevent the screen from detecting touch input while your phone is in a dark place such as a pocket or bag)
See if it happens when the phone is in Safe Mode (ask Bixby)
djlee0314 enabled it...
After searching on google for a while, I found some threads that relates this battery drain with camera settings related to sensors and movement...
And voi la, it seemed to work for the most part.
Removed the phone from the charger at 7am and battery was draining as supposed until 1pm when the phone started getting hot again.
Removed from my pocket because I needed it online... placed it in the pocket in the evening and... cold.
I am starting to think that I might have a faulty unit... I am trying to avoid restoring it to factory defaults... will keep monitoring.
Thanks!

Whats did you do whit this to fix it?
Never experience this issue with my N950N. Try enabling accidental screen touches maybe that will resolve it
hi hope someone can help with this.
I have a huawei p9 32gb EU version
model EVA-L09 emui 4.1.1 (still on) android 6.0 (says no update available)
build number is: EVA-L09C432B182
An issue seems to have developed in the past 2 weeks (i've had it almost a year) - it has decided to close itself down when I try to use the camera. I am using the default/stock camera app not a 3rd party one. I want to make clear it does not happen every time seems (at the moment) quite random/intermittent
The battery was at 79% the first time it happened and a few days ago it was at 55% and it happened. Auto flash was on but flash not activated at the time the phone shut down.
The first time I thought I just hadn't realised the battery was that low but when I plugged it in to charge it said 79% on screen.
A few days ago when it was 55% I was able to put the phone back on after it shut itself down and it was fine/behaved normally since putting it back on - the battery appeared to drain at the usual rate. I even took a few other photos after switching it back on & it didnt shut down. I had been using camera the same morning when the battery % would have been higher & it didn't shutdown then. (& i actually took quite a few photos during that time).
Hope someone out there has an idea of how to fix this issue, though i'm thinking its maybe the a sign the battery may be failing?
I also have this issue, I think it may be a sign the battery is beginning to fail, or possibly the cpu gets too hot. (again first started happening around a year into ownership)
Under 70% battery if i take a bunch of photos it can shut down but would normally turn back on again with 20% less battery. if battery gets less than 50% then if it powers off, it may power back on breifly and then go back to the exclamation mark for empty battery and shut down.
I have tried following the guide to calibrate the battery (let it charge to 100%, turn off, plug back into charger) but it made no difference.
What did help a bit though was ensuring cloud photo apps (google photos/onedrive etc) were set to only upload photos while on wifi and charging.
Hi, I have the same issue with my EVA-L09 with EMUI 4.1.1 build EVA-L09C900B182 bought in october 2016. Shuts down after shooting few photos/videos and can't start it again without plugging it. Once plugged, the battery level seems to be the same as before the shutdown. Seems to happen with any battery level.
If anybody can help solve this, that would be great. I can't decide to change the battery for the moment without certainty that it would fix this issue.

To all of you...unlock bootloader and update firmware. Maybe your issues will be solved. Its a conflict and not a battery issue
Sent from my EVA-L09 using XDA Labs
Any resolution?
I am having the same problem with my L09 and the P9 camera app. Was on Nougat so rolled back to MM in attempt to fix. Also tried a faster SD. No luck with either.
No such issues with other camera apps from Play Store, but they don't use both sensors.
Anybody resolved this problem definitely yet? If yes, how?
Thanks.

I have the same problem since the last 6-9 months.
However I noticed that the problem occurs when I make photos when I'm outside and the weather is windy/damp. I never had the problem when shooting photos inside, always outdoors.
The solution is indeed connecting the phone with a charger (or portable battery) or wait for a couple of hours.
It could be a problem with the battery but it is strange that the phone is ok again after charging a couple of minutes. If it was moisture this idid not yet vanish in just a couple of minutes. Maybe a sensor which is not working ok (or the firmware is not resetting/reading it correctly) ?
I'm thinking of sending my phone into repair for this problem, however I think this is a difficult to identify problem because it does happen randomly (as it seems).
I'm having the same problem, after battery goes under 50% It drains fast, bellow this it only takes 30min of use to shoot down, taking a few photos just makes it drain even faster. And when plugged to the charger it suddenly gets up to 40% . I tried everything software wise with no luck. I bought a new OEM battery planning to change it this week, then I'll post the results.
I am facing the same problem L09C432B395. I observed its somehow being related to cold temperatures outside in my case - it happens only when walking outdoor and the phone is in my hand for a while - so its probably cools down. And than when pressing the camera button I see the message "waiting to sharpen the photo" and then beeeep! battery down to 1% and phone shutdowns. Regardles the battery level.. happening accidentaly and randomly, but only once a week.. and only when taking phone outdoor in a winter time. I did factory reset, re-installed the latest ROM etc but the problem persists. Might be some conflict between battery state and temperature read error?

Update: I change the battery, everything back to normal. I used a OEM battery, screen time is +6h with moderate use during the first row cycles of battery use from 100% to 10%.
Hi all together. Faced the same issue up times (Huawei P9 EVA-L09C432B395, Kamera App 4.1.1) with battery in good state 46 to 76% and taking a picture caused draining it to zero at a moment. Sitting down immediately. BUT only if flash ? is set to bulb-light ?! Tested it several times. Normal (auto/always active) flash is ok - but not bulb-mode...
So, that's obviously the reason - but where's a solution? ?
Some Huawei officials here at xda? ?
Same problem here and without solution yet ... camera causes phone to shutdown and battery indication goes crazy.

Experiencing the same issue on both P9 we have and getting very annoying would be glad to see if is there any solution of this.

These are my exact symptoms - combination of cold and camera gives false battery reading and shuts down phone entirely. Software update hasn't fixed.
I have same problem
EVA-L09C55B383
it's the last firmware
emui 5.0.1
android 7
at 50% battery i make a photo with flash and the p9 turn off.
to turn on i need connect it to recharger.
it's very very impossible.
i think to send it to customer care.
have someone resolved this issue?
i ask to huawei on facebook. i wait a answer.
Any luck with Huawei support for any of you?
Hi,
I'm having the same problem. It's amazing how there's no information at all from Huawei about this issue... it's frustrating. I was planning on buying a P20 during this year and give my P9 to my wife, but if she can't use the camera it's useless. And I will not buy another Huawei if they don't do anything regarding a problem like this one...
Did any of you had any positive experience with Huawei Customer Care?
Thank you!

Did you try yourself any search for custom ROMs ob XDA for Huawei P9?!
https://forum.xda-developers.com/p9/development
I tried Huwawei customer care.
Their best offer was factory reset of all firmware!
Install updates doesn't fix.

Even when connected to charger!!
Even when the phone is connected by USB to my computer and charging, if I open the camera the battery % starts to drop like 1% every 4-5 seconds!!
So the battery is being drained faster than what it charges.
I close the camera and it starts charging again.
Huawei, I was very happy with this phone, now I'm constantly in fear of getting out of battery in the middle of an unknown city while taking photos!
hello everyone I recently found that my mi 8 constantly and always keep disconnecting it self and reconnecting from charger and it freaks me out for security reasons and also bother me. have any one encounter this problem?

You did not provide enough info, this can be caused by a custom thermal, kernel settings, certain Magisk mods, certain Xposed modules etc.
Most likely its caused by something that you installed. So what do you have installed?
If you are using Miui 11 just stick with stock kernel and avoid hacky mods. I use adblock and that's it... No issues.
FYI, charging should ideally be intermittent, and it will fluctuate based on the battery percentage and temperature.
It's possible that you battery needs to be recalibrated. Turn off the phone and charge too 100% I believe that you battery program includes calibration tools. Well at least it looks like you are using Accubattery.
Don't bother believing the myth of deleting the battery stats.bin file, it doesn't help do anything.
Edit : Worst case scenario try another charger or cable.
Hi, About a month ago I installed a custom ROM on my MI A2 , everything was fine but the average temperature in idle mod and with small tasks was about 35 Degree C which was really weird since I've never had overheating issues on this phone. On the other hand when plugged in charge or when playing games / videos or heavy tasks the temperature was rising to almost 49 Degree C. Therefore I switched back to stock and locked the bootloader etc. Most of the Overheating Problem is solved but I can Still feel the phone being warmer than what it used to be, Specially when playing videos on MX Player the phone gets warm and makes me uncomfortable.
I'm on the latest Android 10 build, not rooted and I'm pretty sure I flashed the stock ROM correctly. Also as I mentioned it the bootloader is locked and device is encrypted as it was before flashing custom ROM. also yes, I am using the exact same charging brick and cable that came in the box.
Let me know if you've had the same experience or you have any suggestions or solutions.
Hello, friends. I have an S21 Ultra phone, the Exynos version, since the April 2023 update. The phone has become unbearable with significant issues, although I didn't face any problems before. The first problem is that the temperature rises dramatically whenever I use the phone. The second issue is related to charging. When the phone is, for example, at 85%, and I plug it in for charging, it reaches 100% within just 3 minutes. I only encountered this problem after the April update. I tried clearing the cache partition in recovery mode, but it didn't work. Is there anyone experiencing the same issue?
Yes facing the same issue, is there a way to downgrade at least?
same issue here... can anyone help about this problem
