My P9 with B378 is eating my battery like a hungry monster see atached screenshot what can cause this?
Already did factory reset not working.
I suggest you to show us also the apps consumption... But tell us more details... Are you using SD... As external or internal ...Try to format from phone as sometimes excessive consumption is due to old android files on SD ... Also try to locate which apps is draining more gsam battery monitor may help... And you can reflash from zero but this important you read carefully all threads to document yourself... Other cracks here will help you better than me I am quite new on Huawei...

Here ya go
Have you chosed apps to be closed when locking the phone? Only apps i have running when locking is Snapchat and Messenger.
Facebook is a battery killer, maybe you should try Friendly instead?
Also, have you turned off 4G for any apps? Its probably a good idea to disable 4G for the apps you dont use.
I lose about 10% every hour with medium to heavy use (surfing, instagram, friendly, Messenger and so on).

Apart from androidOS the app that consumes more is email... Could be sync problems?.. regarding Snapchat I cant say nothing as I do not use.. as with muviz... Disable Google backup and check on accounts is someone is getting sync errors...These are fist things to check or try to use the phone without those two/three apps to see if are not properly adapted to nougat for some reason... Or boot in safe mode to monitor how it goes

On B361 my P9 had a bigger battery drain than it had before on B182.
Now on N378 battery life is as good as it was on B182. I'm happy again.
So maybe it's an app that sucks your battery.
Thanks everyone problem seems to be solved now, i disabled or removed all huawei or google related apps now battery life is fine

I am also having really bad drain on B378. Far worse than I had on my previous phone p9 lite.
Android system is eating battery. I have done 2 factory resets now.

After a factory reset it's normal to have bad drain for the first few days, google is gathering stats .

Resetting your phone over and over does not solve anything.
If after 5 days you still have drain then it must be some app or config.
hi, my huawei p9 also have battery problem but its kinda different. today before i restart my phone, my battery was left at 42% but after the restart the battery was at 1% and the phone switched off. when i charge it, it starts charging from the previous 42% percent. the battery is also very unstable. sometimes it lasts for long and then suddenly drops very fast with the same usage. is it the battery problem or the hardware. should i change the battery?
Yes thats a known bug. Im waiting for a better nougat version to be honest.

Beter to have a Oreo one on P9, becuase I think that Huawei will not provide to us better version of nougat.
HI everyone.
I have exactly the same issue as here, "SystemAndroid" (with multiple applications) is taking much battery. Some time ago it was more than screen took, however I was able to identify couple of things which were charming battery:
1. SD card was used on Samsung phone and then swapped to P9, formatting it helped a bit.
2. I disabled "Ok google function" as it seems it was keeping microphone always on - few percentage less on SystemAndroid.
3. I have turned off history of location - it helped significantly, now SystemAndroid is on around 17-18% while screen is around 26%.
What also I did:
4. Scanning for BT and Wifi is off.
5. Network data always on is disabled.
6. Wifi is set to do not keep it in sleep.
7. Only 3 applications has unchecked cleaning while screen is locked.
8. Removing of messanger, whatsupp etc did not bring any results.
9. Removing SD card also didn't help.
10. Factory reset didn't help.
11. Clear partition cache also didn't help
But still.. most of people has SystemAndroid very low, around 6-9%. I have no idea what to do next to get rid of it. What is strange I set all settings 1:1 comparing with my second phone (P10 Lite) and on P10 lite there is no issue with this. Same apps, same setting, different usage for SystemAndroid. I had this with B397 and now with B398. Any ideas what could be the reason?
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

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!

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!
Hey guys. Massive problem here. I have stock EMUI 9 9.0.0.163 installed and I seem to lose 15 to 20% battery overnight when left idle. Gsam and BBS show nothing major or out of place so not sure what is keeping my device awake. Also I have only my main apps set to be managed automatically by EMUI and 90% of all my other apps are manually managed to not auto run/secondary launch/background etc.
Anyone got any idea as to why this is happening? I have factory reset several times and a few days ago my mother used this phone with only WhatsApp and Pinterest installed and she still experienced the same as me.
You had better make a factory reset..
Hello,
I have a problem with the battery in my P9, which has started to behave very strangely. It a Huawei P9 EVA-L09 (Europe) with Nougat currently installed on it, its a couple of years old and have no warranty.
Here is what I know:
- It works fine from around 100% to roughly 60%, then suddenly it drops really really fast (only last a couple of seconds from 20% until it just shuts down.).
- It takes forever to charge afterwards (even though it has been advertised, that it charge really fast)
- It is of course old (but the problem started from one day to the other).
- I've downloaded a lot of battery health/calibration apps, and they all say that the battery is in good health (don't really know about their reliability).
- If it shuts down (0% battery), I can turn it on and force it into safe mode, where it can last over 30 minutes on 1% battery (even though in regular mode it would shut down instantly again).
I've of course searched the web. I've read a lot of places that it can be either software or a faulty battery. Personally I think it would be weird if it is the battery when it is able to stay on 1% of battery for over 30 minutes in safe mode. That seems more like a software issue? However I'm really no expert.
I've tried:
- Doing a factory reset (and not installing a bunch of new apps), which didn't fix the issue.
- Doing the old school battery calibration techniques with charging the battery etc. which also haven't fixed the issue.
Some people have written on this forum about doing a downgrade, however I'm not sure where to get the original Marshmallow OS for a Huawei EVA-L09 (Europe) so I haven't tried it yet. Anyone who knows a place and which version to download for my type of P9 from Europe?
Have anyone experienced the same thing, and have some new knowledge about some fix, that I haven't tried yet?
Best regards
Your phone's battery needs to be replaced. Lithium batteries degrade over time and problems like the ones you are talking about arise. You can look for a new compatible battery that has the code HB366481ECW.
Best regards.
Hello, I had p30pro and was perfectly satisfied with it but from curiousity changed it for oneplus 7 pro and then galaxy note 10+, wasn't satisfied with those devices because of worse battery life than p30pro, I had 8-10h screen on time with p30pro and ~5h with one plus 7 pro and galaxy note 10+. (gsmarena endurance rating is not correct, p30pro according to them has 100h endurance rating and galaxy note10+ has 107h, so I expected battery life to be pretty much the same but its far from that )
because of magnificent battery life on p30pro i changed back to p30pro, but this is second unit I got and battery life is not like on the first one. first one was 1 year old 8/128, current one is 8/256 3 months old and I have like 5-6 hours screen on time with new one which does not satisfy me, battery life is primary reason i got back on p30pro.
usage is the same, same applications installed as far as i am aware
I have screenshot from first p30pro with 8hours screen on time and 25% battery left, it was so great that I had to save it :laugh: and battery life was contant like that
Other pictures attached is from current device, 3h31min screen on time with 38% battery left, so by the time it drops to 25% like screenshot from first p30pro it would be like 4h30min screen on time, big difference. battery life is constant like that
any tips, solutions, suggestions, thoughts?
-i did wipe the cache in recovery
-i tried dark mode
-no app seem to be draining the battery
solutions that i am thinking about:
-wait for 10.1 update for my device and see if there is any changes
-sell this one and get third p30pro (really dont want to do that, I will lose money and time and would be furious if i dont get good battery like on first device )
-factory reset (really dont want to do that, I will lose half a day again customizing and installing everything)
is integrated battery info correct, could there be something /an app that drains the battery but is not showing correctly in battery usage?
FAULTY UNIT?
There must be somethnig draining battery , either delete one by one apk and see if it improved, then you will know which apk was trouble, or hard reset and manually reinstall all apks, do not use backup as faulty apk will do same harm.
Second phone was new or second hand? If second hand you should do hard reset first.., tip for future..
one thing I noticed on screenshot from first device is that I was using only one sim card back then, I turned off second one now and will see if battery improves, altough in Screen On Time thread I see people have 8-10 screen on time regularly with two mobile signals.
"there must be something draining the battery..." can there be anything like that but not showing in battery usage correctly? because everyhing in battery usage seems fine.
both phones was second hand and I did reset them, but from menu, dont know if there is any difference in reseting from recovery?
1. EMUI 10.1 have same battery in some cases may be worse battery than EMU 10
2. Why sell phone if this one is good just need find what eat battery
3. Factory reset thats in many cases fix drain problem but if you wont do that why you not do backup first than make factory reset
Solution
1. Try put all apps in sleep mode settings ---> battery ---> startup apps (there enable sleep mode on all apps only leave apps from where you want get notifications)
2. Dark mode i recommend you use it any time its not save your battery too much but it can help to save battery
3. Use Huawei optimizer app to clean junks and optimize phone
4. Disable synchronizatios
5. Disable GPS, NFC, Bluetooth if you not use it (if you use any navigation than just use GPS when you not need it)
6. I see your Google Chrome use too much battery use instead Kiwi Browser
7. Same about Instagram use light version of instagram or try InstaMod app its better for me
8. Your screen display use 24+ % battery try lower light i have set on AUTO BRIGHTNESS (Tips in settings display set lower resolution)
9. Cell standby try disable mobile data when you not need and btw try put sim in another slot
10. Disable or Uninstall all apps from Google i have disabled Google Movies, Google Music, Google Drive and mayn other apps just disable all apps which you not use
11. I see you are on stock launcher you can try Nova Launcher or Evie Launcher or Microsoft Launcher....(Tips Evie Launcher is one of the lighweight launcher and build for performance/battery i now use Microsoft Launcher which is same as Evie but with little more functions
If you need any info just ask
so I disabled second sim card yesterday and this is result I have now, much better! 1h16min screen on time with 86% battery, which corresponds with about 8h screen on time :good:
can't believe another sim card has so much impact on battery life. my signal is full!
in next few days I will try only 3g or 2g enabled instead of 4g for second sim card to see if that makes a difference.
5 hours & 40% still left, always using data connection. Mainly browsing and watching videos.

I think I found your cause of drain. Go to settings, apps, apps, on the top right click on show system apps, then check for hms core. Click that, then on the top right you will se a gear. Click on the gear and carefully untick everything that has to do with data sharing, analytics etc. Check your battery again and let me know mate ??
