camera causing p9 to shutdown - Huawei P9 Questions & Answers

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!

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!

Xperia Z abnormal battery drainage and Wifi is DEAD

i bought my phone on 1st march and it was all fine (except the stamina mode led notification) until TODAY. I have experienced 2 sudden battery drainage on the same day and the battery can drop like 70% within an hr and the phone became VERY HOT. I have my stamina mode and location based wifi on.
Now my wifi and bluetooth is not working. I have rebooted my phone and switched off the location based wifi and trying to manually turn back on wifi and bluetooth but still failed! the wifi icon keep blinking but never able to turn on again. i also reset and erase everything of the phone and repair the phone once with the SUS. still NO LUCK!
I dunno if the abnormal battery drainage is something related to the location based wifi mode or the overheat killed my wifi or the wifi problem caused battery drain?. Has anyone experienced a similar issue? or just me? heres the battery screenshot.
Hi,
a member (November49) is having problems with their account, but they wanted me to post this for them in the meantime.
Hello mate,
I bought the Xperia Z the day it came out. I sent the first one back because I thought I was experiencing audio issues. The sellers claim they couldn't understand what I was complaining about, as they said caller audio was just fine.. but they sent me a new one anyway. I don't know, perhaps it is my network, because some callers sound muffled or like there is a separate layer of audio over their voices. I might change my sim card because the replacement unit is exhibiting the same behaviour.
Anyway, overheating and power drain. The phone was kind of ok. I was juicing it a fair bit because I watch movies, use the net, HSDPA+ constantly connected etc. All was relatively as expected, then suddenly, I was experiencing a massive power drain and overheating. Overheating while the phone was charging, really small increments in power when charging so it was taking forever, any use of the phone while charging would drain the battery (even though it is supposed to be receiving power), eg connecting to the net, watching movies, checking/sending messages, anything. The problem got so bad, I requested a second product return code from the dealer and was preparing to send it back.
Brain wave - "what if it was a software conflict with an app?". The phone is supposed to be some sort of behemoth and an app shouldn't have such an effect on it, but it was a thorn that felled St Jerome's' Lion. So I went over what I had installed recently and figured it may be a conflict with SystemPanelLite Task Manager. I immediately uninstalled it. Nothing.. no change. Eventually, the phone drained so badly, it shut down. I kept the charger plugged in, let it drink a little and powered it back up. I charged it to capacity. It was limping for a day or two, similar overheating problems and what not, did a second complete drain and shutdown, booted it back up.
Now it seems to be charging as normal, the battery percentage rising as it should, no extreme overheating while charging.. granted it warms up a little, but I'll take that over what was happening before. Tried streaming some video, watching native video, no overheating or exaggerated drainage. I think it's fixed. To be sure, though, I went to Sony's website, downloaded the software update tool, had it check my phone over, it said it was running the latest software, but I opted to do a factory reset and fresh install just to be safe. It recommends you do so if you are experiencing issues.
I'm in the middle of the fresh install now. If no one hears from me again on this issue, you can assume that uninstalling the offending app, draining and rebooting a couple of times and a factory reset fresh software install has fixed the problem. Well... that's what I'm hoping, anyway.
Good luck, buddy.
update: battery was heating up during use, not too much, but getting warm, losing about a percent every minute or two of watching video. Boxed it up. Sending back. I hope the fix worked for you as it did temporarily for me, but ultimately, I think I have a faulty unit.

[Q] Weird battery issue, Razr i, after Jelly Bean

Hi all,
I have weird battery issue with my Razr i xt890 and I'd like some help. I have tried googling for information, but there's too much noise and I can't find anything suitable.
I'm asking on this site because I know the people on here are really knowledgeable.
My Razr i (with Jelly Bean) seems to have erratic battery readings. Sometimes it'll drop to 6%, and then go up to 90%, and jump around to points in between. I have even seen it drop to 1% and then go up to 6% (or something like that).
Needless to say, this makes the phone unusable because I don't know when it's on low battery so I can charge it. Furthermore, twice, it has reported low battery and then automatically shut itself down.
I hope someone can help with this, because I'm really stuck. I bought this phone overseas, and I don't really want to send it back overseas for warranty repairs.
So, some history.
Before the issue:
This is a stock Razr i, running Retail GB software. When I bought it, it was running 81.5.31002.Retail.en.GB 4.0.4. I upgraded to 81.5.39001.Retail.en.GB 4.0.4 and it's been running fine until this issue happened. I normally get about 4.5-5.5 days of battery before I recharge the phone.
This is stock software. No root. No bootloader unlock. No custom roms.
The issue:
I charged up my phone yesterday, and unplugged it from the charger at 100% battery. There was a notification that 91.2.29001.Retail.en.GB 4.1.2 was available. I selected 'Later' because I was busy at the time.
A bit later (maybe about an hour?), I went back to the phone and checked for updates, and selected to download the update. After it was downloaded, I noticed the battery was about 95%, and then I proceeded to install.
I figured 95% power should be sufficient to perform an upgrade.
The install took, maybe 10-15 minutes? At first glance, it seemed successful, but when the phone started up again, the battery reading was at 100%.
I distinctly remember thinking 'This is impossible. There's no way it could be 95% before the install, and 100% afterwards'.
I played around with the phone a bit (to try out Jelly Bean), and after a few minutes, the battery reading dropped to 60% or something.
That's when I knew something was wrong.
Since then, the phone battery reading has been erratic. If I plug it into a charger, it takes a few minutes and then shoots up to 100%. Unplug it, and it drops to a low level within minutes, and then goes up and down like a yo-yo. Twice, the phone went to a very low level, and then shut itself off.
I've tried various charging/unplugging cycles, and nothing has worked yet (Although I didn't have the patience to try an 8-hour charging cycle yet).
Please see the attached images to see what I mean.
The graphs are just bizarre.
I also did a factory reset (from the Privacy menu rather than 'recovery') but that didn't help.
At the moment, I haven't tried to root the phone or unlock the bootloader. I am still keeping the option of warranty open.
I can't think of a reason why this is happening. It doesn't seem to be a simple calibration or battery stats issue. I think the battery is working okay (because it was fine before the upgrade), just that the readings are wrong.
The phone is operating okay in all other respects. If I ignore the battery readings and the 'low battery' alerts, the phone continues to work ... except when it shuts itself down.
Another theory could be that ... because I upgraded without plugging the phone in, perhaps there was insufficient power during the upgrade and caused some corruption, and I have a faulty software/firmware? Not sure how I could test that though.
Any ideas, any one? Please?

Jelly bean download issues
Hi, I have had exactly the same problem after downloading jelly bean. It even died when plugged in charging. As I had only had the phone for three weeks, I took it back to the shop, Phones 4 You, and they exchanged it for a new phone and told me not to download jelly bean until they let me know it's safe to do so. They said that it was a software problem. Prior to this the battery life was outstanding and I am very pleased with the phone. Phones 4 You gave me an excellent service.
Fixed!
For future readers ...
Someone on the motorola forums (see second reply on this thread) mentioned a possible solution which was to manually install the Jelly Bean version again. I decided to give this a try.
After some more research, I discovered that it should be possible to manually apply official Motorola (ie. OTA) updates using the stock bootloader (via the bootloader recovery feature). No unlocking, no root needed.
I gave this a try ... downloaded the software (keeping to the same version), placed it on an SD card, went to recovery and selected 'Updated from external card' (or something like that) and followed through ... and it has worked (Although this time I kept the phone connected to a usb cable throughout the upgrade). My battery readings are back to normal again. I didn't lose any data or apps as a result of this 'manual upgrade'.
And I am presumably still under warranty since I didn't root nor unlock the bootloader.
Other readers may consider trying this for themselves, however, I cannot guarantee that it will work for them. I can only say it worked for me.

I don't have the phone yet (supposed to get it tonight) but having read quite a bit it seems Moto suggests a factory reset after upgrading to JB in order to sort out battery drain etc. I think I saw it in the battery stats thread in RAZR i general.
I send my Razr I back to Germany (living in The Netherlands myself) yesterday! Had the same problem, only my battery get down to 0% all the time, so the phone shutsdown itself every 1 minute till 1 houre. (I'm from the topic: Auto shutdown (battery problem). I think i get my new one next week on wednesday. Dus the JB software manualy update works for more people?

I think the problems described in this thread are relating to strange battery spikes in percentage and not a general drain of battery.
The problem is that everyone seems to be different. Some people report these spikes, some people are reporting high drains (which turning off google now or factory reset seem to fix) and some people (luckily me!) have had no issues at all - just an even faster phone
I did do a factory reset, though not immediately after the first JB upgrade. It didn't help.
I think describing this issue as battery drain or high battery usage is not quite correct. The battery is actually okay*, but the phone's indication of the battery capacity jumps all over the place (and sometimes causing automatic shutdown). I can see how it can be confused with battery drain though, especially if people only observe the reading going down (but didn't see the reading going up).
* At one point, I kept the phone screen on as an attempt to drain the battery. I got about 6 hours screen time (ignoring the intermittent battery low warnings) before I gave up.
Since I now have a phone with JB which is working, my guess is that this bug may not occur in all phones with JB. Instead, it seems to be triggered by something that happens during an upgrade.

i have the same problem. factory reset did not help me and i feel i made a mistake i have choosen this phone.i had motorola mobiles before even bought one to my wife.i know that motorola has a conservative atittude.i thought giving them a last chance now i know it was a mistake
Thanks bengtan.
I was having similar issues and a manual install of JB appears to have solved the issue.
Have you had any luck fixing your phone? I have the same problem since a few weeks ago. Bought a new battery and tried two calibration programs, but the issue persists.
Same here. I am on KK 4.4.2 and have the problem since yesterday. What to do?
Same here, my ROM is cm-11-20160524. After 3 years of usage I thought it's the battery and replaced it with a new one but the issue persists.
This is very odd, I'm here after my dad has the same issue and it looks like I'm the 4th poster to report the issue within 50 days after the thread hadn't any replies for over 3 years! Did any of you recent posters resolve the issue? I had a spare Razr-i and my dad took it to a phone repair shop where they swapped both batteries and the issue was still the same with the other battery, so it seems it's nothing to do with the battery itself for all the posters here so far.
Was there some recent update that spiralled all the phones into the erratic behaviour recently I wonder?
I'm trying to advise my dad what to do:
Try fix the issue on his current phone and keep using relatively old tech phone
Use my spare phone (same type) and keep using relatively old tech phone and try sell old XT890 for parts
Upgrade to brand new phone with latest tech and do him for a few years longer than the XT890 would.
Any feedback appreciated!
The issue flatened a bit now. After 2 weeks of brave usage the phone keeps the charge now normally with rare drops in between. So it's still not on an acceptable level but improved magically. I do not understand the physics of this behavior.
I'm having the same strange behaviour since yesterday!!
battery level drops when pluggin the charger,
after several minutes level is jumping to 100%.
whith unplugged charger, level in general inconsistent jumping up and down...!
could this be SW related? planned obsolescence?
edit: android 4.4.2. systemversion 990.43.74.XT890.Retail.en.EU

I'm now looking for a copy of the new firmware: 990.43.74.XT890.Retail.en.EU to try to resolve. If anyone knows where it can be found I'd be very grateful if you could point me in the right direction...
Same problem here.
I bought a new battery. No changes.
I than did a complete wipe, unlocked the bootloader and installed CyanogenMod 11 (this one http://forum.xda-developers.com/razr-i/development/rom-unofficial-cyanogenmod-11-t2966855). No changes.
I than completely drained the battery (made sure of it) and left it on the charger over night. Now I don't get those weird spikes, the battery just drains really fast (about an hour an the phone is powering off).
Maybe I try a different ROM, or go back to KitKat
I found this but I dunno how to use it ??

Battery issue and restoring completely to stock

Hello everyone,
I have been using a Xperia Z1 for around last 6 months and updated to Lollipop 5.1.1 two months ago. Everything was fine until last week when my phone started to get affected by the battery bug.
The phone works fine and the battery gets discharged in leaps. For example, when I use the phone from 100%, it goes down in the usual way, let's say for 1 hour usage it drops up to 90% which is quite normal. But, when lock the screen and keep it idle for sometime and when I take it back, the battery has dropped a leap, usually by 10-15%.
Yesterday, I was using the phone normally and kept it idle for the entire night and battery has been dropped only from 85% to 79% without stamina mode. That's good. However, when I restarted the phone in the morning, the battery suddenly dropped to 18%. :crying:
I tried calibrating the battery, charging/discharging cycles and removing batterystats.bin. But, the issue is still here.
I think my phone has been affected by the famous Xperia battery bug in Lollipop which means that my battery is damaged. But, before replacing the battery is there anything else that I could do to overcome the issue. Any suggestions are greatly appreciated.
+ My phone is rooted on stock 5.1.1 (14.6.A.0.368) with XZDualRecovery and locked bootloader. If I repair the phone with PCC will it cause any harm or bricking since because of the customer recovery?
Claiming warranty is out of option since the phone has been rooted and flashed with custom recovery.
I don't know why people call it a lollipop bug. There will be a time a battery reaches its end of live. That's what has hit you right now. Your descripte symptoms are from a dying battery. I have seen some dying battery's from me or friends. The battery was holding the charge normally and suddenly no more.
Replace it and all should be fine again.

But, can this happen on a phone that is just 7 months old? Thats what makes me to think that this could be a bug.
I have the same issue, but mine drops to 0% and after waiting some time and booting it the percentage is back up. I have my phone for 2 years now, and the problem appeared in Lollipop also.

It's okay for a 2 year old phone as Lithium batteries wear out with time. In my case, it's kinda disappointing...
So, after searching the entire Internet, I can understand that this is a common issue with Xperia Z1 and Z1 compact and replacing the battery seems to be the only possible solution. I searched EBay for a battery but couldn't choose a good quality one. Can someone guide me on this please?

Your battery is definitely dying and it has nothing to do with roms. Get a battery that the seller claims to be OEM. That's your best bet...

Thanks for the tip. So, I searched for an OEM battery and ordered it along with some tools required for the disassembling. I will keep posted once I replace the battery.

Don't think that it will resolve your problem.
I changed my internal battery about one month ago and when two weeks passed I started to experiment the same bug ? again
It's not only hardware problem, it also software problem, I believe.

You are correct becouse I experience som drops in the range of 5-20% in less than a minute and once 30%. All the time while the phone was in standby mode except once where it did it right in my face (10%). My battery status is reported being fine. I also forced shutdown the phone as per the calibration method for non-rooted phones. Though I did notice dalvik cache wasn't rebuilt and so there is no way to have it refreshed manually except system updates which does this.
Anyway I did remove some apps and did some changes and after this I have not had any sudden drop for weeks. Two of the apps where Truecaller and Facebook official app. Will check though if it was a third one to. I believe one of these or both where playing havok. Especially the Facebook app as it takes liberties I find suspicious, is buggy, can crash the kernel (any app that can do that is doing shady work IMO) and had the addition of a "Video Player" service that was running permanently after you launch the FB app once. I instead use Metal for Facebook now. Pretty much same experience, only 10MB RAM used instead of 90MB and no batter y drain either or any other problem. So in short I believe one of these where the culprits and since many use the FB app that might be the one playing badly with Sony Z1 system.
And If you use Adguard also check if there are apps getting high ratio of ads blocked (or analytics data blocked). Might be some dont get proccessed right in the battery system due to it calculating it wrong. Google Frameworks, Google Contacts, Play Services, Mobilestorage Checker and a few more I disabled the ad filtering for. Though this did not change the battery drop problem previously. It only went away when I uninstalled named apps above.

Can someone make Kernel/Mod with disabled overheat protection? Will donate.

Hello,
recently I bought LG G Watch R and after updating to Marshmallow the watch started turning off randomly, and was unable to boot to the system without being on the cradle. I've read a lot about it on the internet and tried all sorts of solutions, but without success. Then I found that my temperature sensor is giving wrong data. My watch is idling at 50 - 55C and when put on cradle temperature immediately drops to 40 - 45C (overheat protection turns it off at 60C). So is there a way to turn off overheat protection or change the temerature the sensor is reporting with Kernel/Mod? I'll be glad to donate if someone is to make such thing.
Also excuse my mistakes, I'm not an English speaker.
Cheers.
Have you ever found out a solution? I think the most common thing to do is to buy a new battery, but I ordered one from China so it's going to take a while until it arrives and I'm hoping to try to improve the condition of my current battery a little.

Unfortunately, I haven't found a solution yet. I was about to do the same thing as you, and buy a new battery, but then I read a post on reddit about a guy with exactly the same problem as me, who bought a new battery and the result were disappointing.
Do you have exactly the same issue as me? Because I've read about people's watches shutting off but not because of wrong readings of the temp sensor, but rather battery issues.
When you receive the new battery be sure to update me on the situation.
Thanks!
To be honest I didn't check the battery temperatures. Did you use an app to do so, or adb? I will check and let you know... it might indeed be more battery related than temperature.
I had exactly the same issue.
When my g watch r was charging on the cradle it worked flawlessly. When I removed it from charging it turned off randomly, sometimes it managed to boot and stay on even for hours, but most of the time it turned off instantly.
I thought the problem was either on the battery or on the power regulation ic, I didn't think about temperatures.
So last week I've bought a new battery, replaced it, and tada! The problem was the battery indeed!
The smartwatch is running perfectly now, apart from the bugs and the errors of aw2.0

For temp check I'm using app called System Info For Android Wear. You can check your temps to be shure.

I'll try Wear 2.0 and if the problem persist (most definetely will) I'm going to try with new battery. The problem with new battery however, is availability and ridiculously high shiping taxes here in Europe.
I know this is old now but has anyone solved this issue?
I've replaced my battery yesterday but the problem persists. The temperature floats around 50C and it rises to 60 quickly and shuts off if i do anything. Please share if you have a solution. Thank you.
I'm facing the same issue, battery has been changed but still getting hot and shutting down... If anybody knows a solution !
I have the same issue. I replaced the battery, even downgraded from 2.0, but the watch still frequently shuts off. I was able to get it to work for a good while by putting it in the freezer for a few minutes before powering it on.
Edit: its as if the cpu temp sensor has lost calibration, but since the freezer trick works, what about a mod that would move the shutoff threshold a few tens of degrees up?
same for me, it works after having spent few minutes in the freezer and then shuts off

The same thing happened to me, I changed the battery and the problem is still happening.
something new?
This just started happening on my G Watch R as well. Sometimes the heat generated from my wrist is enough to cause the watch to shutdown or reboot from overheating. If it isn't a failing battery, as some of you have noted through a battery replacement, then what could it be?

I had exactly the same symptoms.. but not any more.. after I changed the battery1.5 months ago.. No power off since then...
no idea what else could it be.. maybe some app actuality coursing overheating.. ?? But mine sometimes just died in between of factory reset.. so in cant be custom app..

P9 Battery draining when not in safe mode even after 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.
