Battery drain!

I don't know what the hell is going on with my Note 4 (SM-N910F), but my battery is draining a lot faster then it ever has. A couple months ago i rooted my phablet, tried out two or three different custom ROMS (Omega was one of them), but my Note 4 got so hot it got into a bootloop as soon as I entered my PIN. I reflashed stock ROM and it was back to normal again, but lately it started to warn me for low battery (the 5% warning) and turn off itself in seconds even when i had 20-30% battery left. This didn't happen every day, but it was annoying. So i re-rooted and installed CM 12.1 thinking it was the 5.0.1 and 5.1.1 stock updates. The first night I charged it all night but only got 83% battery when I woke up 9-10h later. Today when I was scrolling FB with 35% battery left, the phone warned me about low battery and dropped to 5%. Is it possible that the battery drain is because the overheating could have caused some damage to the phone/battery? I tried calibrating the battery two times, did everything I could find on the net, but nothing helped. I would like to know if there could be something more than the battery that could cause this because I don't want to buy another one for nothing.

you could try to re-calibrate your battery, you can find a app for that on playstore.
is your phone still getting hot when your battery drain is high?
you could post an image of your battery stats from settings or better battery stats so we can see, why it's empty so fast

I already tried that two times, it did make the battery last a bit longer but the 35%-5% problem is still there. I'm new to XDA so I can't upload the screenshot but I can't see any app or activity that's draining the battery. I've done everything I could find in the forums (lower screen brightnes, turned off auto wake, even downloaded kernel adiutor and changed some settings a guy posted) but nothing has changed.. I'm just wondering if it's the battery that's the problem or something else so I don't fo out and give out money for a new battery if it won't help..

And yes, my phone is still getting hot when the battery is draining fast.. I do have an insurance that I could use but if it's just the battery then I can buy a new one. I forgot to mention that the phone gets pretty hot when I charge it, somewhere above the battery connectors. Eather that or the micro-USB connector, or even both at the same time.. The cable has turned yellow just under the connector so I don't know if it could be the charget that messed it up. This started before I even flashed a custom ROM.

Well I couldn't take it anymore and decided to downgrade my phone back to 4.4.4 which it came with. 9h on battery, Spotify was playing for 3h, played a little on Snes emulator, facebook, chrome, and I still jave 56% battery left. Seems to me that I was one of them who got the f*cked update for 5.0.1 and 5.1.1.. my phone is back to normal with speed, battery usage and heat. I'll let the battery drain completely today and see if it will turn off at 25-5% like it used to. The worst thing is that a game I used to play dosn't work on 4.4.4.. but it's still worth it!

Random turn off

Hi,
I have a Note 4 SM-N910C variant that is almost 3 years old.
Starting from 5 months ago the battery level would start dropping fast from 35% to 0% in like 2-3min after which the phone would turn off. If i took out the battery and insert it again, start the phone again it would show around 30% battery level. After a while it would start doing the same fast drops in battery level and so on.
I got a new battery, not OEM and now it doesnst do what i was facing above but it randomly turns off no matter if im doing something with heavy or no load on the device.
The turning off usually happens after the device goes bellow 50% battery level.
How can i test if all the components are ok other than the battery which seems to be faulty in my opinion.
I did order a new original OEM battery but it will take time to get to me.
I want to find out if the rest of the components are functioning without faults so i can decide whether i should get a new phone or not.
Please assist.

New battery

I know its not the same behavior, I have 2 note's. Mine is only a couple of months old while the one from my wife is build in 05/15. Her phone when we just received it would refuse to charge above 96%. Sure the phone would say 100% but as soon as you unplugged the charger it would drop straight to 96%. It did this on 3 different batteries, exactly the same behavior. All these batteries are OEM. When you plug it in it would go rapidly to 100%..
Anyway, I wiped the cache on that phone and since this it charges normally.
Been comparing the battery drain and both phones are using around 6 to 8% per night while on stby with wifi on.
Just try this, it may help you!

Thanks for the replies.
I did try wiping the cache and even did a factory reset.
I rooted the phone 2 days ago to try and recalibrate the battery but i didn't help.
I think the situation isn't degrading cause from today the phone is constantly hot and the cpu is running at around 48 celsius with 7-8% load.
I'll see what happens when the new battery arrives, maybe the phone is heating up cause of this maybe not. It's even eating the battery from 100% to 0 in 2h with no real load on the phone.
Do you guys think a benchmark program will force it to thermal shutdown if this is the issue.
I'm still trying to find out if only the battery is faulty or i have a dying phone.

To me you have 2 problems...a faulty battery and a (new) software problem on your phone.
Constant being warm with a cpu load tells me something on your phone is running all the time consuming your battery and causing your phone to heat up, unless it behaved the same before the factory reset and rooting?
You are rooted so try Wakelock detector for root to see which app (if any) is causing your phone to behave like this.

I will try wakelock to do its thing during the time i sleep. But if that doesnt help ill try a custom rom. Im not gonna factory restore and go back to stock rom. Gonna move away from that and see what happens.

Moto X play Battery Suddenly dead, like from 60 % to 0% and power off.

I m facing this problem in all N 7.X roms, Even returning to stock firmware till problem exist. My phone turnoff on any present like 60 % shown and suddenly its shows 0 % and power off and when I trying to start its shows battery drain but when I connect charger, after few seconds its show 60 % battery then I am able to start devices.
Kindly suggest solution If anyone have.
Thanks in Advance.
(Sorry for my bad english)

Hi, I've faced similar problem 2 or 3 times, although for me it was around 20-25% (on stock MM). I don't know if it's a solution but seems it helped for me: charge a mobile just a bit so it turns back on, then use it until it really goes to empty battery and charge it to full.

I can confirm this. ALso around 20-30% or lower. Often will crash out right when I wake the phone up and often when using the camera. Using Lineage OS 14.1 nightly. Haven't figured out a solution, but restarting the phone will bring battery life up to where it was and often will allow me to finish the charge, or at least get me to a charger. Maybe just old batteries?

Hi,
Happy to inform u all my problem is resolve with replacing the battery. As per my opinion this is the best and final solution for this kind of battery problem in moto x play

I've had the same problem with my Moto X Play since November 2016
I've had the same problem with my Moto X Play since November 2016 and today the same problem continues ... I've changed the ROM many times since 2016, but the problem continues and turns into 15% and 30%.
I have Android N and TWRP 3 on my Moto X Play and I realized that the battery had power, because in TWRP it is possible to see it. I think this problem is not necessarily in battery, but "in something else" ... it's very strange ...
I have a question: how does Android know my battery? A file? Is a software inside it responsible for seeing my battery charge?
I think that is our problem.

Have you got the solution? I replaced the battery with genuine one, but still phone is shutting off at 70-80%. I also tried flashing PureNexus ROM thinking it may be a Nougat ROM problem. But the problem is still there.

Old battery is the reason. I faced it too in 2018. Then I got a new battery. Worked fine until a few days back, when it again started shutting down on opening the camera. Don't know why exactly. Most likely it's just the phone showing its age (I bought the phone in March, 2016). But other than this battery/age issue, it's working fine. Really a very well built phone

Is it dead? (97% battery shutdown)

Couldn't find this exact shut down thing and none of the recent spate of 0% all of a sudden threads covers the 97% battery shutdown aspect to this. I ramble a bit, bare with me.
Had the nexus 10 from new (fk knows how long - 6+ years?)
Replaced the battery from a reputable supplier maybe 9months ago.
All has been good.
I installed lineage 14 and life was better.
Its essentially a youtube,iplayer, email terminal now.
Past few nights it just started shutting down. (fully charged)
Sometimes when switching Youtube videos, sometimes just skipping forward.
It worked for a bit whilst plugged in but even that isn't happening any more.
Its behaving like the battery is empty but when plugged in the battery indicator says full.
I have just tried to reflash. Got new lineage on it through twrp.
Boots to recovery and then I'm just trying to put gappsPICO on and it shuts down again, and thats whilst its plugged in!
Wont boot through to lineage setup even (i know it would fail/dead screen without gapps but I thought I'd try)
*Live update*
I deleted the battery stats file and it was still showing full charge but whilst typing its changed its mind and is accepting a charge!
Hope it was just the battery stats file (means I've just scrubbed it for no good reason other than that new lineage is better lineage right?)
Assuming the battery doesn't over charge and blow up and that the shutdown behaviour continues - this smells like a hardware fault right? A.k.A R.I.P Manta?
Wow, rambling. Sorry

Charged overnight. Reflashed and even got gappsPICO on as well.
Started to setup firstboot and the issue came back.
Thermally related hardware fault is my guess.
What's the current options for a similar product? High Res screen, doesn't need to game, nougat or later OS.
I thought there would be a cheap option but all I can find are things like the Samsung galaxy Tab 2. 300quid...
What say you?

Maybe helps.

--- Hi i used/tried 4 new batteries until i gave up hope. One day i started to feel that i have to get my nexus 10 working so i started testing different stuff. My fix was, dont use any rom/kernel that is 3.4.67. Use 3.4.113 using roms or install that kernel. I hope this helps and please tell me if it helps

Do I need to kind a rom based on it or can I just flash a new one?

Hi, try rhis 5.8.5 resurection remix for nexus 10
Fingers crossed

Nah its terminal.
Screen now flickers whilst in recovery.
3 finger salute works
I can flash in new recovery ok.
I can navigate recovery menus fine, change interface settings but the miute I ask it to actually do anything, wipe, set for sideload or flash zip already on the device it flickers then dies.
Poor thing

Who'd have thunk it. Replacement battery died after 9 months.
Put the old one in ( cracking it open being the last resort)
Back in business.
Lineage 15.1 and oreo.
Boom, back in the game.

Battery percentage issue on z17s

Hi.
Yesterday I was using my Nubia z17s as always and before going to bed I decided to charge it, since battery was at around 20%.
When I connected the charger, the screen went off and it didn't wake up, no matter what I did, although I could feel the fingerprint scanner vibration when I used any of the registered fingers. So I decided to hard reboot the phone by keeping the power button pressed.
To my surprise, when the phone booted again, the battery percentage showed 3%. I left it charging overnight and now it's working but the battery percentage is stuck on 3%. I'm pretty sure it's more than that, since I've been using the phone for more than 6 hours and the battery percentage hasn't dropped a bit, and the phone is working (I've made an received a few calls).
A guy at work suggested letting the battery drain completely until the point the phone shuts itself down, and then charging the phone up to 100% while off, so the battery is calibrated and the percentage is fixed. But I've always heard that it's not a good idea to let a battery drain so much. Another problem is that I fear not being able to charge the phone again once the battery gets below 3%.
Any ideas? The phone is running latest Mokee 9 Premium.
Thanks in advance.

Remove "batterystats.bin" in the System folder

I had already tried that. But deleting that file just resets the battery usage statistics. It has nothing to do with the battery percentage

It seems to me that you will have to make a full data backup and perform a factory reset.
ps and which firmware in use?

Hi, I forgot replying.
I finally got the phone up and running again, and the issue seemed to be firmware related.
I was running the phone on Android Pie based Mokee ROM. I finally let the phone discharge until it shut down and charged it while off. Battery got up to 100% and the phone seemed to work fine. But, a few weeks later, something similar happened again, so I reverted to the stock firmware (still stuck at Android 7.1.1) and the battery issues went away.
I recently tested the Android 10 based Mokee and found that it reports battery level very differently than the stock firmware. Before flashing TWRP and the Mokee ROM, the phone was showing 88% battery left. Just after booting Mokee, the phone had apperently dropped to 78% and I also felt quite a huge battery drain. And it had only taken me around 5 minutes to install the recovery and firmware. So I guess the Mokee firmware doesn't handle the battery very well on Nubia z17s. It's a pity, since all the rest works very well, and I quite liked the Android 10 experience. On the other side, I was unable to make Magisk work under Android 10, and Google Pay is a must for me now, so I once again went back to stock firmware.
