Battery dropped from 30% to 0% in a few seconds - Nexus 6P Q&A, Help & Troubleshooting

Battery dropped from 30% to 0% in a few seconds and phone shut down. Unplugged from car at 40%, took pics from 30 minutes, while taking a photosphere, around 30% from the batt history, phone suddenly shut down. Recharged in car for 15 minutes a day it went up to 18% and then started working fine without shutting down.

Welcome to the battery bug! Send your phone to RMA while you can.

You believe it's that problem?
It's my very first time and outside was -2 degree...
Let's see if it does it again...

I wouldn't panic yet. Custom ROM or kernel? Check under normal temperature conditions...

No custom ROM, no custom kernel.
Just systemless root on new 7.1.1 Jan patch

Hi! If I buy a new phone with a new battery, I will not experience this problem? Right?

Don't buy one without a warranty. Huawei quality control appears to have been very poor for this phone.

I use my phone during winter. We go as low at -25 and have no problem whatsoever with the phone shutting down.
You battery is degrating. Have it RMA if it's under warranty.

I just got off the phone and google they told me that they are no longer sending out replacement batteries that there will be a software update to fix the problem and to run it in battery saving mode or put the phone in safe more......really?! C'mon this is complete bs

actually, if they really did tell you that, that's not bull****, in fact, it's fantastic news. That means they were able to find the problem and that it was software related (obviously, many different devices with the same issue)

Another critical bug on the universal :-(

I just found another painful bug....this one is related to charging (battery). I normally put my qtek on charge all through the night when I go to bed. For the last 4-5 days I have been unplugging the device when it showed 100% charge, put it on standby (no wifi,btooth,gsm etc.) and made sure there were no applications running. I usually leave it in the standby state for 2 hours while I finish my morning exercise.
whenever I return, I see a power loss of 20%!! I was shocked to see how I could loose 20% in 2 hours ith my device on standby mode. this time, I even made sure I pressed the power button before I closed the lid, and still...no luck :-( I still lost 19%
I guess the problem is, when the charger is connected and the battery gets completely charged, it stops charging further. I guess it reaches a fully charged state within 2 hours, and the battery starts to drain all through the night...and wm5/htc don't start charging once again when the levels go down....i'll have to do a cuple more tests until I can totally confirm that this is the bug...until then, are anyone of you guys experiencing the same problems?
Another thing I forgot to mention, once again I charge my battery from 80% to 100%, and it lasts through the entire day(12 hrs) and drops to only 40% with highhh usage (bluetooth ON throughout, gsm on with 3hrs talktime, and some light gprs usage). so it really is not a problem of my battery as I see it!
Cheers,
San
Hmmm. I hate to say, but I don't see that problem. But I do have the unlocked JasJar Universal from HTC, not the qtek. If this happens with other qtecs, maybe they load a custom software that is acting up. In fact, I could leave the device on for two straight hours off a 100% charge and I don't think I'd lose 20% unless the phone was on too.

have you tried charging your device for well over two hours before unplugging? (around 8-9 hours of charging for instance?)
I don't really think it has anything to do with the qtek rom/device. the qtek rom has the least ammt of customisations on it...
I still suspect that the charging process halts and it starts to drain the battery....but the os doesn't reinitiate the charging process once again....hmm
I'll have to wait till tomm before I can do another round of checking....tomm, I want to charge it....and before I unplug, I'd remove the battery and put it back and see what it indicates...I suspect that the power would have already dropped to ~80% by then...that's the only explanation I can think of at the moment....

Hi Dreamtheater!!!
I exactly follow you as far as charging is concerned and I hv a Jasjar....just to inform you...I started charging yesterday at 11.30 PM and just got up to see the charge..it is 100%...no power loss...

it shows 100% for me too...but in just 2 hrs, it drops to 80% which is weird! from then on, it drains normally...
I still need some time to nail the exact cause for the problem...hmm!

Hey dreamtheater, I charge my Exec overnite everynite just like you. Usually at least 7 to 8 hrs everynite, but I have yet to experience what you mentioned here. My Exec always start fresh from 100% and by the time I get home at nite, it will drop to about 70% so no, I'm not getting the batt drain issue like you do..
I did not experience any such behaviour with my Qtek. It charged fine over night and had 100% battery when unpluged.
Are you sure your's does not wake up for some reason after you suspend it?
Dreamtheatre, I charged my XDA Exec overnight (7 hrs) and after 2 hrs with GSM/UMTS radio on the unit lost 5% battery charge.
@DT,
You need to set the device to switch off after a specified time interval. This can be done by going to start>settings>battery>advanced and check the device timeout box. I usually set it to 1 minute.
Last night i was browsing on my JJ and fell asleep while doing so, IE and notes and inbox applications were still open. When i started, the battery level was 93%, i browsed for about 10 minutes over Wifi before i fell asleep. The device shut itself off and when i woke up the battery level was 82% which is prportionate to my 10 min WiFi use and probably 1 minute standby time before it shut itself off.
Try it out, i'm sure you will stop seeing the massive battery drain
Cheers.
Another thing. Contraty to what people think, keeping the universal's battery topped off improves battery life. Prevent it from dropping all the way to say 30% or so. You will notice the difference in battery life in just about a week or so
Another source of battery drainage i've found is when i'm charging my Exec from the USB connection on my PC - If I leave my Exec connected and put my PC into standby, it will literally suck the life out of the battery over the course of a few hours!
I think some of you have got me wrong...let me restate the problem...
I charge all night
Wake up with 100% charge
Pull off the charger
Leave it on standby for ~2 hrs (no apps running, gsm, wifi, all off)
Come back, and find a ~20% drop
Back to my findings now.......
Another morning, no luck :-(
It had 100% charge...I pulled off the battery, put it back in and restarted....still showed 100%, so I guess it really was fully charged after all. This time I turned off receive incoming beams as well....left it for a couple hours, and was disappointed to see 82% when I got back :-(
However, through the day I get excellent battery life....all day's use ends up consuming roughly 30-40% charge which is excellent compared to my prev xda2 which would comparitively loose all of it by eod. I guess if I park my device in flight mode it tends to start draining quickly....now that's my only available reason or cause that I can think of....
tomm I guess I won't put the device on flight mode and leave it just On instead. This is weird because its just me having this problem :-(
San
PS: I'm using the regular ac charger itself for charging...hmm
DT, I disabled PowerSave and switched off the GSM/UMTS radio on my Exec. After about 8 hours I had lost about 30% charge. So your 20% does seem high. It could just be the battery as loss of charge is not linear. Why not let it drop to say 60% and then do your test again. By the way there spare batteries seem to be available now for the Universal.

Battery get flat after 8%

Hi there,
I'm using P6800 and started experience abnormal on the better.
The battery warning on 15% charge, it will get flat very fast. And when reached 8%, the phone just initiate a shutdown. Had you face this problem?
1 more thing is that when the phone say full charged, once the plug pull off, it show 99%.
Mind is till virgin and unroot...

This is normal, mine is showing the same, but still at 8% upon shut down you can still power it on several times until it reaches 0%.

Mine doesn't do that... If i take my tab off power i have 100% for around 5 to 10 minutes, depending on usage. Also it shuts itself off exactly on 0%. Most of the times I see 0% battery for quite a few minutes before it powers down.
what did you do to make it like that? Rooted?
I'm a rooted stock 3G
My battery stays at 100% for a bit unless i am running some heavy duty processes. However I do also experience the battery going flat very quickly after it goes below 10%. I also found that very odd, and I think it would be at 2% when it initiates the shutdown process.
I would like to hear any thoughts as well on why this might be happening

I didn't do anything to it. Browsing the web on wifi, 3g disabled it goes down to 0% before shutting down. When I play angry birds I can see 0% battery quite a few minutes before it shuts down.
Yes, my device is rooted.

Shutting down on 15% would be normal for a broken battery.
My htc desire shuts down on 2-5% and I thought about sending it for repair. Unfortunately I didn't but now seeing my 7.7 can go down to 0% I think I should have. It is totally not normal for an intact battery to behave like that.
Could you please post how long your battery is lasting on average?
New Galaxy Tab 7.7 Same Battery Issue
I have the same issue with the battery, i tried root and battery calibration; nothing happens. My tablet is brand new it has less than a month.
The battery life is not bad but like other said: Battery get flat after 8%. And its shutdown but you can turn it on several times until you get a complete discharge.
What can i try to solve the problem?. It looks like a bug or software related issue.
Someone has any idea how to fix it?. Thanks!

Nexus 4 signal and battery problems

Hello there,
So, I had my phones screen repaired a few weeks ago. For the last two 2 weeks or so, after the phone loses about 30% charge it will start losing signal and then regaining it and this will occur for about 5 mins and then the phone will shut down weather its at 15% or 70%.
After this, everytime I reboot the phone it will turn off within 20 seconds even though it will still have plenty of charge on it. However, It is a dirty shut down. It won't say phone is shutting down, it will just turn off instantly
The only way to solve it is to charge the phone. It will say it still has charge once I put it on charge and that the battery is not fully drained and once it reaches a high enough percentage (e.g 80%). I will be able to use the phone till it drops round about another 30% and the cycle will begin again.
I have tried switching to multiple ROMs and wiping everything of course so it must be a hardware issue. Do you think it is a dodgy battery? Or what could be causing this issue? Any help would be greatly appreciated
Thank you

Battery issues

Dear XDA,
Since a few weeks I began experiencing problems with the battery of my Galaxy Note 4 (SM-N910F).
It all started with the phone lasting a lot shorter per day and suddenly shutting off at around 5-8% battery left.
Today it was the worst I've ever experienced. I make a short list of what happened.
Charged to 100% overnight and taken charger out at 7:30
Went to the gym, 98% left after 1 hour idle
Bumped an extra 4% when transferring files from PC at 15:10 (from around 78 to 82%)
Watched 10 minutes of Under the Dome and did some Whatsapp
Read an article on the internet
Phone was suddenly at 28% at 19:00, shut it down for a bit
Powered on at 19:25 with only 18% left
Phone died at 19:30 with 14% left. 2h and 40 min Screen On Time. 12 hour standby.
Still able to boot but can't get past coloured Samsung logo
LED Notification stays blue and can keep booting for about 30 more times.
So basically my phone died after 2h and 40 min Screen On Time with still some charge left.
This is the worst I've had so far.
The weirdest part is that the Notification LED stays on after trying to boot it once. The only way to remove this is by taking out the battery.
When the phone was new I was able to at least get 4-5 hours Screen On Time depending on brightness.
Things I tried to solve it:
Full charge cycle and emptying it
Factory reset
Checking for unusual activity (wakelocks)
I've checked for any wakelocks but I think this might be a defect instead.
Can anyone please help me? Any advice is appreciated! Thanks in advance anyway!
Kind regards,
Daniel Collignon
Anyone?!

Try a new battery, it can become 'weak' after a while.
Sent from my SM-N910F using XDA Premium 4 mobile app
Don't worry ! I have gone through this too . A log or a screenshot of BBS , System battery graph would help us . Please share it
well my phone is n910H. it lasts less than a day and it dies when it reach 30% and when i connect the charger it gives me 0%. does this means the battery is faulty or is it a software issue ?
Me too!
I have the exact problem stated in the op. I am pretty sure it must be a callibration issue because I've tried too many times the *#0228#. I've tried taking out the battery and putting it after some minutes. I've tried off-charging, on with screen off charging, on charging, fast charging, slow charging, everything and I have at most 4 hours of use, with 1 or 2SOT.
Sometimes I charge it and it stops at 70 or 75%. Today, it stopped at %50 (off-charged) and I removed the battery, waited 5 minutes, put it back on and it showed 100% (still off). Battery lasted less than 1 hour (okay, I was playing candy crush and clash of clans ).
I use my phone without the power saving mode for a snappier performance, but it's impossible that the battery lasts so little time.
Could you solve it? or just bought a new one?
Battery drain
I have same issue on my Note 4 for a last few months. And it's just getting worse.
Today it dropped from 48% to 5% and turned off.
I even took it to Samsung service and they told me that everything is OK with phone and that I have to change charging equpment.
I did that and it didn't help. It's happening again.
Help please?

Horrible battery life?

I got an S4 i9505 replacement yesterday from my insurance company. It effectively seems to be new phone and battery, anyway when I turned it on it had 70% battery left, I logged into my various things and it sat about downloading and restoring and installing a 5.0.1 update, the process took about 30 mins and at the end of the 30 mins I had 9% battery left, I connected to the charger and it was full again in 30mins which I found odd.
Anyway let it sit on the charger all night, took it off this morning and with 2 mins of screen on time I am already at 94%, I can't see how this thing will last the day.
I am not a newbie, I have things like sync and GPS etc turned off and screen brightness lowered however in saying that even at the lowest setting it seems very bright.
Any ideas?

You cannot jump to conclusions based on this. Your device was setting up, your battery needs to settle etc. It's normal to discharge faster.
Try a few charges / discharges and see if it helps.
But most likely if it's charging way too fast and discharging fast as well, the problem is most likely the battery itself, it might be a old one.
Right ok, been using this for a few days now, with basically everything turned off I am getting 1 hr screen on time, something not right but can't figure out what
