Trying to fix this android os draining my battery, turned some things off, charged my phone and rebooted.. well now screen isn't reported as being on, and it's not showing up in the list of things using my battery. Plz halp.
Mine does this from time to time, or the screen stops recording time on - usually charging it and unplugging resets and fixes though. I put it down to reboots/kernel flashes etc on my side.

My phone under a full charge will go off. The problem is, there's no pattern, it will turn off because of different apps, sometimes in a middle of drafting a text message, or while using twitter. So I ruled out the possibility of being apps that causes issue.
When phone off, and when I attempt to turn it back on the phone will not get passed the boot animation, sometimes it will, and will automatically shutdown right after. There are times it will stay on pass the lockscreen and go no further unless plugged.
There are too many inconsistencies in battery life, if phone goes off at a given percentage, it will not display even close to the same battery level after reboot.
At first I thought it might be the ICS ROMs (CM9 by elk... and Ice Cold Insomnia by Cnote...) then I reverted to CM7.2 RC1, but I get the same problem across the board.
I downloaded a battery drainer app from the market. Will drain battery til I get 0%, then will spend an hr or more charging phone til its full, while it remains on. I timed the amount of time it takes to turn off under ICS or GB, no consistency at all. Anyone has suggestions as to what might be happening to my phone?
Was having trouble with both issues, pulled battery with phone on, waited a minute, put battery back in, both problems fixed!
isnt this bad for the phone? Im having horrible battery life so I'll try anything but just wanna make sure

You wouldn't want do it if on a regular basis but you can try turning phone off, pulling battery out, putting it back in after a minute and if that doesn't work, try my method.
I would wait until the battery is super low and then reset network settings under the reset menu. Power down, pull battery and sim wait 30 sec to a minute and replace everything. Then plug in the phone first and then reboot. Let it charge completely and for about 20 minutes more after it reaches 100. If you do a lot of rebooting I have found the phone has issues. I only reboot with the phone plugged in, otherwise it drops 2% every reboot..
Be careful, I did that with a ZTE Zmax 2 once (75% charged battery) and it sent a phone into a bootloop. The only means of fixing it was that I luckily had a 2nd Zmax2 laying around and used its battery on the bootlooped phone which remedied the problem. Both batteries work fine , I just swapped them between the two phones.

I used to worry about this too. This is my first LG product and it MAY be different but at the Sprint store the first thing they would normally do is pull the nattery to look at the ESN. They never bothered to power it doen forst so I asked a couple times and was told it will mot hurt anything. I had Samsung products for uears and have done battery pulls at all levels of charge and for many reasons, but I never had a problem as long as the battery had enough juice left to boot the phone. If not I had to charge it, LoL.
Just thought I would share, I personally wouldn't worry.
I know on my old Nexus 6 pulling the battery with phone on was only an issue with fsync disabled using a custom kernel. I think most phones have built in protection to stop this from damaging the file system.
so a battery pull is your fix? lol some ppl should be hard resetting every so often regardlessi reboot at least once a day
hi
my v20 phone battery draining was about 1% per hour before (about 7% totally ) and recently increased to 2% during sleeping time overnight. (draining 15% overnight in sleeping state)
it seems that during day either performance off battery is decreased.(about 5h with wifi and screen on usage)
Fast charging while second screen is On , is slower than when it is off therefore when second screen is Off , fast charging goes better . exactly , first 30 mins fast charging makes about 40% battery charge(instead of 50%) and after 60 min leads to 85% and full charging taking place after about 100 min instead of 80 mins.
another important thing is that sometimes shades have been seen on the LCD that many users have complained about it.
phone information is :
Android security patch level: September 1, 2017
BASEBAND : MPSS.TH.2.0.1.c3-00045-M8996FAAAANAZM-1
KERNEL : 3.18.31
BUILD NUMBER : NRD90M
SOFTWARE VERSION : V10g-AME-XX
MODEL NUMBER : LG-H990ds
my actions are as follows :
phone is factory reseted. No third party apps is installed. [especially social media apps.]
battery calibration steps for not rooted phones is taken place.(turning off the phone and charging several times repeatedly).
testing battery drain in safe mode in done and didn't change results
turn off location services and location scanning for WiFi and Bluetooth scanning
turn off WiFi being On during screen is Off.
turn off auto sync, NFC, GPS etc.
not using auto brightness.
not using comfort view .
turn off location services and location scanning for WiFi and Bluetooth scanning
second screen is off during test overnight. (either with second screen is ON with faced down to lower brightness in other day test )
phone is in Air Plane Mode and all data services is off.
system apps like Google services and Play and Assistance is limited by permissions.
following are some advanced battery drain overnight figures of my phone for more analyzing.
any help with this issue is appreciated.
While I don't get extremely bad battery drain. The few times I've noticed it going down a bit faster than normal have had Android system at the top of the list or at least 2nd in place. A reboot usually fixes it for a while. This has happened in every ROM I've tried. Also I swear that stupid Wi-Fi scanning when WiFi is off option in locations settings turns itself on when it feels like it. I rarely turn my location on and I've checked a few times and that feature is on for whatever reason
Power down.
Pull battery.
Hold power button for one minute to discharge any juice that may be on the motherboard.
Let phone sit for 30 minutes.
Put battery back in.
Power up.
The motherboard and battery should now be re-calibrated. If you still have problems, try a new battery.
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?
Hi everone. I have the Samsung Galaxy S5 (Octa core version). Recently, i noticed that the battery had a strange behavior, so i planned to replaced when i finish my exams. During that time, the phone started to shut down randomly, so i bought a new battery thinking that would resolve all the problems, but it won't. The phone keeps shutting down alone, it happends when the battery percentage is below 60% and for turn on again i have to connect the phone charger or remove the battery and put it in again. Some times, the baterry percentage changes -/+ 15%, even from 40% to 3%. Oddly, sometimes the phone just get a black screen when i using it or the screen suffers some kind of distortion and shuts down.
Already did a factory reset and did some test on safe mode, but no luck. Curiously, when the phone is charging, there are no problems of any type.
Any clue of what could be?
