Guys, I really need your help and opinion. My sister is experiencing a HUUUUGE battery drain on her Galaxy Note 4 [N910C]. It started about month ago, she claims that it happened after one of the Google Play apps updates, she doesn't know which one exactly because there were few of them and she doesn't remember.
I upgraded the bootloader and modem, flashed custom recovery TWRP and rooted the phone, installed custom ROM (Nemesis) but that didn't help at all. I personally suspect some hardware issue because the drain is crazy, please take a look at the BBS dump. What's most peculiar is that the drain happens also when the device is TURNED OFF, tonight after turning off it went down from 82% to 6% overnight!!
How can I troubleshoot further? Or should I just go to a service point?
EDIT: Forgot to mention that she replaced the battery with a new one so battery age is not the issue.
Turned off as in button power off? in which case the battery is low quality.
Yes, turned off meaning power off, it happens on both the original battery and the new one. I believe that there must be something else draining the battery.
As the phone is off then if the battery can't hold the charge then it is either old and or low quality

After successfully booting into android for the first time my battery life in android skyrocketed down, but that didn't really bother me.
The real problem is that even in WINMO my battery life is less than half what it used to be, and even after a night (8 hours) of charging (In a wall socket, not USB) its not at 100%
this has me very worried, any ideas? thanks in advance!
did you read anything before you started this thread...........
yes, i did. everyone is having a problem when they charge in android it gets to 90% then they switch to winmo and within minutes it picks back up to 100%.
this is not the case for me, my battery does not jump back up, it drains quickly even in winmo, and when it gets low its not just reading it improperly it just dies, so no this is not the same problem
did you know there are fixes .......and that your problem is not new at all....i am sorry to say that this is a know problem and you would want to ask in the thread of what build you are using and if you really wanted help you would post what build your using and what kernal , but no one can help you at all when you simply state you have battery issues
drain your battery in winmo till it dies, so the battery resets, then charge the battery again till full, it should be allright again.
thank you dipdap i will try that

I strongly advise you NOT to do so. Draining a Lithium-Ion battery entirely is detrimental to its overall life/capacity. So instead of ruining your battery (or going a step towards ruining it), simply turn off your phone, charge it until you get the green LED, boot back to WinMo and it should be alright. If it isn't, look for another way, but completely draining your battery should not be the method of choice.
nobody said to drain it copletely, just till winmo dies, which should be fine. I do this once every couple of months by accident, and have never had a problem. I agree that you should not drain the battery completely though, so, make sure as soon as winmo dies, plug in to a charger.
what rom are you running? I am using shubcraft 1.5 and mine charges to 99% And I can get a full day out of my battery with pretty decent use.
Are you using setcpu cause that could have a major impact also do you have wifi,gps or bt on. I know gps has been known to cause some major drain while in sleep mode.
There is also a thread where people are trying to find solutions to the high amount of drain in the development forum.
We use current widget to create a log and monitor Our drain. You should be seeing less than 10ma while sleep I usually see between 3-7ma while sleep
Funny how when you are watching your battery it drains faster. When you are watching the clock time goes slower.

You can look at this thread
http://forum.xda-developers.com/showthread.php?t=770903
It was very helpful for me to identify how much current is being used while in sleep mode and active.
Download "current widget" from market and monitor your current supply for 30 minutes during your phone's screen is off.
Yeah with the screen off you cant see any thing but thankfully the log will be written for the current widget every min.
If your current comes out to be bellow 10ma during this time then you are doing good and should last you one day of usage else you need to pinpoint what is drinking all the juice even while your phone sleeps
Read the thread ALL OF IT, it will help you understand better.
Cheers.
alright thanks for all the help guys, the battery drain actually worked although i felt strange doing it, but still my android life isn't so great, i would love for it to work completely though because the only wquivalent option on my carrier is the Captivate (Galaxy S) and that thing is ugly compared to the HD2
such problem
I have such problem with battery drain under WM, after i run and quit android, but i found a solution, just pull out your battery few times next just recharge it and it will be OK .
My N4 started to have battery issues after the kitkat update lasting no longer than 6 hours even turned off. It also started to take longer to charge and gradually this got worse and now all I get is a red light when plugged in but I can't turn it on now.
I guess my battery is stuffed, but could it be that the upgrade did this or (I hope) it was just a coincidence.
I've ordered a new battery and tools but I would appreciate your thoughts on this.

It has been written that the battery shouldn't be run down past 15%. I don't know this for a fact, but that could be one of the issues. Another issue would be an app that is constantly running, but there's no way to find out if you can't boot the phone.
As far as the upgrade is concerned, it's iffy at best because a lot of people have upgraded with no problems.

Hey guys, How you all doing ?
First of all, I recently got in hands a Nexus 6p! Bought It used (8 months of use), and its perfect, everything os ok.
Then, I rooted It and now i'm using the Android O ROM, with franco kernel.
But, I've been noticed that the battery sometimes drains 2%-3% too quickly. And yesterday my phone shutdown at 18%!
I was experiencing the 2-3% drain on 7.1.2, but not the shutdown.
I dont get that bad SOT, like 3h-4:30 is still a thing for me.
What do you guys think ? Is It bad battery or software related problem ?
Should I consider doing this trick and go back to Android N ? https://www.google.com.br/amp/s/for...-6p/help/nougat-battery-bug-fix-t3559250/amp/
Here is one print from my screen on time and accubattery.

First of all, going "back" to anything is not going to help you. Android 8.0 is not the issue, it may be a degraded battery, especially if you are having early shutdowns. Please open the Health page (Saúde) and post it. That is where you will find your estimated battery capacity relative to a new battery. You should have a few full charges before this percentage stabilizes. Try draining it as low as you can go (or when it shuts off), and then let the phone charge fully until Accubattery tells you your phone is fully charged NOT the phone reporting 100%. It's common for the phone to continue charging 45-60 minutes beyond the phone reporting 100% and you need to keep it on the charger until completely full to get an accurate capacity estimate. Hope this helps. Boa sorte!
Okay. I went back to 7.1.2, early shutdowns got resolved, but the 2℅ drain not.
I followed all the steps of the guide I posted, changed governator, etc..
It have seen to got a little better. Will report back after a few days of usage with accubattery health status.
Thanks!
6P has been shutting down early for a while now, usually like 10% or less which never really bothered me. Battery life seemed decent, but I never really tracked it.
Last week it started going off at 15-30% at times. But it can be random. Might go below 10% one time, next shuts off at 30%. This was on a prior version of Pure Nexus. So I tried updating to the latest build. First charge it shut down at 40%. Same crap tho, random shut off times. Today it shut down at 48%. By shut down, I mean it just suddenly gives the low battery warning, reports 0% and turns off. Many times I can restart the phone, and it will say like 1-3%, and let me use it for a while before turning off again. This most recent one at the 48% shutdown, I restarted it, showed 1%, used it for a while before it turned off again. Restarted, now shows 18%.
Wtf? Is this just a charge level reporting issue? Tried battery repair/calibration apps/techniques with no success. Nothing looks bad with regards to apps/services draining the battery. I tried accubattery and says I'm at 70% health. Don't even get 2 hours of SOT. Have a replacement battery in the mail. Think this will solve the issues?
It's known issue with some factory battery's for some reason the phone is thinking the battery is low and shutting down even though it's reporting let's say 50%. I didn't have this issue until I bought a cheap replacement would shut down at random percentages especially when opening something power hungry like camera. The only thing you can do is get a replacement and change or send it in to get changed. If you replace it yourself I suggest testing the battery before you put the phone back together. I think the 6p is a great phone and worth it to replace the battery. That just my opinion best of luck. ?

@ 70% your battery has been toast for quite a while. This degradation doesn't happen overnight. If you did your research and purchased one of the "good" replacement batteries from a known good vendor then, yes it will likely completely solve your problem. If you just bought a random battery from Ebay or BFE, then you may have another dud on your hands. Suggest testing the new battery with Accubattery before sealing it back up. Best of luck.

Interesting. Did notice a couple of the times it shut down, and it was this last time at 48% as well, was when opening a power hungry game. And yes I agree the 6p is still awesome today, by far the longest I've had a phone. Considered getting the Pixel 2 XL, but it's a waste of money to me if I can get the 6P working well again.

Hmm, yeah I grabbed one off ebay. Had over 500 sold though, so hopefully not too terrible, but I will test.
I think it has really degraded in the last ~6 months. Possibly from numerous partial charges? Got a new job in April, and I'm often traveling to different sites only 10-15 minutes apart. During this time plug it into my car for Android Auto.
Thanks for the help guys!
In the same boat (But I have a solution for me)
2 weeks ago I upgraded from a beaten GS6 Edge and I am quite fond of my new phone. However I started experiencing this issue, ignored it for the first week since my S6 at 100% battery would die in an hour or two, if I'm lucky. Then the battery problem became an interest to me. I had read a lot of threads on the issue, some saying its a hardware problem, and some saying just a software bug that hasn't (or can't) be fixed. SOOOO at this point I said screw it and just accepted my phone battery as it is. Installed Dirty Unicorns Rom, messed with settings, and boom a breakthrough (I think). DU has a feature called smart pixels in which to save battery life turns off a percentage of the pixels. Wasn't to fond of this at first, but in order to make my 60 - 70 percent battery last i set it to the lowest setting. Every since then I have had maybe one random shutdown, it's only been a week and a lot could change but for me its working pretty well.
Sidenote: I found that not using camera apps, nor Google assistant had also prevented random shutdowns (this helped me with smart pixels enabled and disabled, if you wanna give it ago on stock)
Hello guys. I am experiencing random shutting downs on my phone too. I bought it in January 2017.
What I have observed and today was confirmed is that I have these unexpected shutting down when I charge the phone with fast charge. Today my phone was at 60% and shut down. When I plugged my phone on the charger, the phone was again at 60%!!! How was it possible? I think the problem might be the battery or the internal controller of the charging system...
Guys I am experiencing a very strange problem with my battery. Starting a few months ago the phone began to drain battery a lot, lasting for about 5 hours depending on the use. That problem only got worse with time and now the phone cannot keep on at all. It shut down even with 85% or more battery. If you plug the charger it will boot and the battery will be about the same it was when it shutdown. Yet the phone won’t stand the boot if it is not plugged in the charger.
I have no idea what went wrong here. Ampere show health as good but clearly there is a problem. I even downgraded the OS to 7.1.1 to check the battery life and it stood the same...
Any suggestions? Sorry if my English is not perfect, it is not my first language.
Known battery issue. Get battery replacement.

I got same issue on my Nexus 6p. So now I have only one chiise.... Replace the battery
Just go on eBay and get one no originals available. My first replacement was a dud so if your doing yourself test the battery before you put the back on. You can just put your case temporarily over top. The sellers need good ratings so if you have any issues they will immediately send a replacement.
