Battery Issues... Sudden death

Hi everyone.. I need some help with this problem.
This is what happened .. Last night before going to sleep i checked the time on my kaiser, then made sure no applications were running and pressed the power buton (for sby). The battery was at 79%. This morning the phone was switched off. When i press the power to turn it on the battery was fully drained and completely dead. This is not the first time this has happened. And it doesnt matter at what charge the battery is. IT JUST HAPPENS... By the way i have it in flight mode since i never use it as a phone. I contacted the rep in my country and said they can check it out, but i would prefer avoiding the 2 weeks waiting...
ANY ideas...
Thank you all

Either there is something wrong with your battery or you've got software installed which drains your battery all the time.
Disable or uninstall monitoring programs or third party apps that can cause battery drain.
Did you install new apps recently?

ive had that issue once, gave me a rlod!
i basically ran pocket mechanics file cleanup...
took a while so i gave it 5 minutes, then bam! battery dead and had then saw the infamouse rlod. i was scared ****less
but after a ressurection with aid of some htc guy,
i had to hard reset(many of the files became corrupt) and it never happened again.
sooo try a hard reset

can you explain the ressurection with aid of some htc guy?
thx

Hi everyone.
Thanx for the replies. Well i havent installed any software lately and the only monitoring software i have is the battery status which i dont think is the problem since the reason i installed was these sudden deaths...
is there any way to find out if a certain app drains power when in standby mode?

Battery suddenly dropping happened to me twice... re-charged the battery and had no more issues concerning battery dropping. Possibily, it's some kind of app that keeps on running even though task manager does not trace it... That's my point.
To see whether your Kaiser is consuming more power than needed, close all running apps and leave it on until it reaches the idle power consumption (my Battery Status says 40-50 mA).
Also, complete discharge-charge cycle could help re-calibrate the battery gauge.

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] Randomly auto shutdown (battery problem)

Hi guys,
I have the Razr I since 3 days now, i orderd it via ebay on a german website. I really like the phone, its amasing fast and works really great. I've compared it with the Galaxy SIII and Xperia Z from friends, and the Razr I wins on almost every thing we testet (loading webpages, opening apps, scrolling etc).
But since i use the phone, there's something wrong with the battery (i think!). The phone just randomly shuts down for about 40 till 60 times a day, my record for keeping it on is about 1 hour.
This is what I know for now, by observing:
- The phone is working correctly (on of off, doesn't matter)
- The battery gives an empy signal (but isn't)
- Due to the empty signal Android thinks the phone is empty and starts the automaticly shutdown process
- When the phone is off, i can just turn it on and the battery level is where it was before
- This cycle happens randomly, in 1 minute til 1 houre...
What i've done so far:
- Searched on google, a few similar problems, but no solutions
- Caliberate the battery
- Factory reset
- Disable apps that may couse a restart (but i don't think its a software issue tough)
- Playing with different settings, profiles etc
All those things doesn't change the randomly showing cycle that i've wrote above.
I also send an e-mail to the company where i orderd the device, so i maybe can return it and get an other one.
By the way, the phone was on JB when i received it.
Does anyone have any idea what the problem could be? Or is it just what my own conclusion is, a broken battery?
I hope someone can help thiking about my problem!
Cheers

Could be a bad flash...
A friend got almost the same problem with his SII. Or faulty battery
Check with that company and demand for a change

Nexus 6 Restarting and Battery Issues

Hi Guys, I really would like to ask some help with my Nexus 6 in which the battery drains to fast and some message always appearing once I try tuning it on back again.
It all started just last week when i noticed that my battery drains to fast, in which lets say the battery has still 70% of power then when Im about to using, the fone will immediately turn off saying the battery is already 0%. But once I try to charge it, it'll be showing that the battery has still 70% of power. Aside from that, every time Im about to turn it on after the knowing that my phone has still enough battery or once I tried to plug the adaptor. A message will appear stating that "Apps updating 15 of 135" something...
I've tried to reset my phone hoping that something that I've downloaded probably have cause my phone to malfunction, but still no use. The battery is draining too fast and that updating of apps is still showing and it'll take atleast 4X I need to turn on my phone with the charger plugin in order for the phone to turn on properly.
Would anyone might know whats the problem or whats causing my phone to malfunction in that way?

The battery is busted, the same thing happened to me. I had to send the phone back to Motorola and they sent me a refurbished one back and its having the same issue. I'm just giving up on this phone and getting the note 4

It could be updating of apps or system. In that case the message "Apps updating . . ." is normal after reboot.
When you have a slow data connection updating can take a lot of time, including battery drain.

Same problem with my n6. But only in high mountains... No restarts when in airplane mode or without sim card

camera causing p9 to shutdown

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!

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!
