Hello,
Yesterday, my nexus 4 while it was in deep sleep turned off itself and in order to boot again I had to plug it into my pc (wall would be ok also).
When the phone booted there was a drop in battery details from ~90% to 0% and then back on ~70% (when booted).
So, I cleared the battery stats with the battery calibration app from play store and see how it goes.
Today, the phone shutted down again, while it was in deep sleep, with a blue flashing light (from the notification led).
This time the phone booted without charging it and there was a drop in battery details from ~60% to 45% (not 0%).
I run the device full stock and rooted.
Maybe there is a defect or a software issue. I'll flash again the stock rom, do a factory reset and I'll report back.
However, I was wondering if someone knew what the blue flashing light means...
Thanks in advance for any suggestions and help

Cheers,
I've been having this weird problems with my N7 32GB recently, it started to happen about 3 weeks ago, then it stops and starts again this week.
It seems that the battery percentage is not being reported correctly, I remember the first time it happened is that I still have > 50% battery, then
the device shutdown and booted and then the screen flickered and shutdown and booted again it went on in this cycle for about 2mins and every it
went into this cycle the screen flickers which is kinda alarming and asked that it be connected to a charger. This week it happened again, I have
85% battery charge, and then device went into the same shutdown - boot, cycle and asks to be connected to a charger. And every time this happens
when I first boot the device the battery percentage shown is way less than that of the reported charge just before it shutsdown. And today it happened
again, the device has about 70% charge and it just shutdown, but this time without the shutdown-boot cycle, so knowing of the issue, I attached it
to my usb to charge and booted it, and it shows that it only has 11% charge.
Any idea on why is this? and how to avoid this issue? I have already installed Battery Widget Reborn and DS Battery Saver.
BTW, Im on stock non-rooted 4.2.1
Thanks.
These issues started up when I was on slimbean ROM and franco kernel r102, but I don't think its a software issue. My phone would randomly reboot at around 70% battery and sometimes around 20-40%, and when it would restart it would show 5-10% battery and sometimes wouldn't start because the battery was completely dead. I recalibrated the battery by removing the battery bin file after a full charge and did all the necessary steps to do it over and over again. When that didn't work I did a full wipe and flashed stock factory image. I even recalibrated battery again, and now the phone shut off over night (5 hours in according to the battery stats), and when i turned the phone on again it showed 10%. I'm scared my charger sometime down the line messed with the micro usb port and shorted my battery or something.....whats even freaking weirder is that I would have auto rotation screen issues where when I would plug my phone to charge, auto rotate wouldn't work even if i enabled it, then would start working again randomly....any help would be great before i drop another 300 on a new nexus.
Does anyone else have a massive battery drain in Kit Kat? I can charge my Nexus to 100% and in an hour or two it's completely dead with blinking red light. I tried restarting to bootloader when it was at 5% but it was still on for like a half hour. Once I restarted my phone, my battery read 0%. I'm thinking it may be time to change the battery if no one else is having this problem.
I suggest you to reset the battery stat from the recovery. The probability that this works are low but is better then nothing.
How do I do that from recovery?
Edit: phone was charged to 98%, rebooted into recovery to see if I could wipe stats in TWRP, rebooted again, phone reads 28%, 3 minutes later it read 66%.

To wipe battery stats in TWRP:
boot into TWRP recovery
/advanced/File Manager/
folder /data/system/
click batterystats.bin
click Delete
reboot system
If you can't see the folder, you need to mount the data folder.
Well I switched to Philz Touch, do I have to do the same thing then?

You should have the wipe battery stat under advanced in your recovery.
The right step to follow are:
1. charging the battery FULLY
2. wipe Battery Stats
3. don't charge the device until the battery still turns off your device because it empty
4. now again FULLY charge without interruption
Wiping battery stats does nothing, see here: http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/ . Sounds like your battery is borked. May need to send away for repair. Are you still under warranty?

Yeah I figured. Thought it was a KitKat bug at first but then it started getting ridiculous. Phone was at 70%, started taking a photosphere, phone shut off, and when I turned it back on it was at 3%.
No its not. Bought it off Craigslist. Just gonna order a battery off eBay for $18 and replace it myself, see if that fixes anything.
I just got out of a similar problem.
My battery percentage was jumping all over the place.
It would charge fully in about 5 mins, and die in about 20.
Everytime I restarted the phone, it would read a different percent.
I ended up running the phone on full brightness, with like everything turned on to drain the battery all the way down.
& Everytime it would shut off cause it had no battery left, just restart it and keep draining it until when you reboot the phone it no longer turns on(because the battery if fully drained of course).
That's when it is really dead.
Then just charge it to 100%, and keep it charging for about 20 extra minutes once it hits 100%, and now it's back to normal!

That really worked? Any problems with it since and is this a common issue with the N4? For some reason it won't die when it's in the bootloader even though the percentage read 5.
So yesterday it was so dead that it gave me the red blinking light, should I charge it when that happens again and should I leave it off while charging it or turn it on and not touch it?
How many times did you have to do this until it straightened itself out?

I am currently having WakeLock problems, but I do not beleive this was the cause.
I was able to restart it after it died about 4-6 times, till it was fully dead.
Then I charged the phone, and kept it off the whole time.
I installed wakelock detector to make sure that wasn't the problem. I had this problem on the stock rom even before I rooted. So the problem hasn't persisted since?
Hi guys,
I have a problem with my nexus 6p's battery. My phone is always shutting down as soon as it reaches around 20% left. I tried a full factory reset, different roms but the problem is still present.
The strange thing: I can't boot into android after it shut down. But: I can boot into twrp. I could run my phone for 2hours in recovery mode. I made about 10 backups and deleted them immediately.
The display was on and on 100% brightness.
Is it possible to recalibrate the battery? This is so annoying!
You probably need a new battery. Download AccuBattery from the Play Store, and use it to check the health of the battery.
Yeah definitely the battery I had similar issue. For now you could just keep the battery topped up but in time will start doing it at random times.

Sounds like a battery that's done...get a replacement...they're not that expensive.

Once you emptied it in recovery, try charging and quickly (with fast charge like 10s should be sufficient) booting then without using the phone, letting the phone charge and stay 1h30 at 100%.
Then let it discharge and when you reach the 20%, you need to have the minimum discharge rate (airplane mode, no heavy app, screen off). Every like, 30mn, check your percentage and screen off again.
Has anyone had an issue similar to mine? My issue is that the phone never shuts off when i'm using it. Randomly, a couple of times a week, i lock the phone after using it, and when i go back to turn it on, i see that the phone has shut off. I can turn the phone back on without needing to put it on a charger. Running PN + EX kernel if that matters.
So for the past few weeks my battery has been draining faster than the speed of light. It will get to anywhere between 30 - 70% (usually about 56%) and it will just turn off. Like straight to dead, no powering down.
When I try to turn it on again I get a white screen with a picture of an empty battery.
If I plug it is, I get the charging screen showing a battery percentage the same as it was when it crashed.
I've done a factory reset, wiped the cache, tried it with no third-party apps, all sorts. But it's still the same. I'm having to charge it 4 or 5 times a day and it's only getting about 30 mins of usage before it dies.
It tends to happen the most with the camera or Snapchat but I don't think it's related to those as it will also do it in other apps and even the lockscreen.
Is it time to call it quits and send it to the phone shop in the sky?!
I had this weird problem with my battery too! MXPE on stock nougat , as soon as I charged my phone to 100% and plug out it used to drop below 80 in 2 minutes ! and then when the percentage hit ~20% It used to turn off showing that white screen you mentioned, however when I plugged the phone in it would start charging at ~15% ! so I tried recalibrating my battery and it is surprisingly effective !
here is the method:
1) drain your phone battery until it shuts down.
2)power it on again and you will see that white battery low picture. plug the charger for 3 or more seconds and out, it will boot up again but as soon as the Rom boots up the phone will die again . do it multiple times.
3)charge the phone while it is off until 100%. turn it on and drain the battery as fast as possible (max brightness, volume, streaming videos on cellular data and running benchmarks will do ) till the phone dies again.
4) repeat (2)
5) charge the phone up to 100% while it is off ! and there you go your battery is recalibrated and good to go!
Obviously, this will shorten the batteries lifespan but since I believe you have it for a long time It won't be an important matter!
Thank you. I think I'm going to bite the bullet and treat myself to the new OnePlus 5T when it goes on sale tomorrow but I will try your advice as this will be a good backup phone to keep for emergencies as it's not worth much to sell on or trade in.
Try removing the back with a heatgun and unplugg and plug de battery.
I'm having the exact same issue and tried the same solutions, no help. It's dying now after a couple minutes. I'm carrying around a battery pack.
Seems to me my troubles started after updating to Nougat. You?
