I have Nexus 6P 2 years old running on Stock ROM 8.1.0.
The battery timing was good about 4 hour+ screen on time but yesterday my battery was behaving abnormal like massive drain. So when I restarted the phone it was stucked on 19% before the restart it was around 70%. It remained stucked on 19 for several hours and now the issue has become aggressive that I have to ait with the wall charger to use it. It means its not charging. The battery shows "Plugged in, can't charge right now"
The port is fine
Changed several chargers
Restarted many times
Cleared cache
Calibrated
Left over night
Both power on and off charging have no effect.
The strangest thing is that it was 3% last night and when I woke up about after 10 hours it was still same. usually it used to drop 3 or 4 percent.
Now I restarted the phone ans its on 2 percent NOT increasing while on charger.
Any help?

Hey guys. I am experiencing the most strange battery problem ever. I am on Darky 10 RC6 with ZSJPG modem. Now I wanted to calibrate my battery so I completely used it till it switched off, turned it on again but it switched off completely indicating that the battery was finished.
Then I plugged in the charger while the phone was off and it started charging. After 5 hours it was still not fully charged, i waited another couple of hours but still not and then when I plugged out the charger and plugged it back again it drained to around 25 % .. I switched on my phone and it shows me a different battery meter everytime I reboot or start again and its not even charging at a good speed now. Please help
Now the phone vibrates in a while by itself and everytime I reboot, I have a massive battery drain of around 10 percent and if I charge my phone it charges so slow, like 4 percent in 1 hour :s
And now ive unplugged the charger and actually the battery meter is increasing. It has increased from 18 to 24 in 20 mins :s
Are you charging by the mains charger or the USB charger ??
how long has this been happening for ? its more likely to be an issue with the rom.
if it bothers you that much, Return to stock rom and compare battery drain..
if battery life is a lot better with stock, the problem is darkys rom, so i would switch to something else.
maybe make your own in the romkitchen.org
I am charging from the main charger, not the usb. It did not happen before, as I have been on the darky Rom since a few months. Even this Rom was flashed 2 weeks ago, this just started last night when I drained the battery the first time to calibrate it, i put it on charge all night only to find it stuck on 75 % after 6 hours or so, when I unplugged the charger and turned on the phone, the battery drained to 25% and that is when all these strange things have started to happen :s
have you tried to wipe battery stats ??
you should do this AFTER calibrating the battery,
otherwise the battery can give false information due to it being confused about its actual percentage
Yes I did, and that has made things worse as the battery meter is now increasing and the phone vibrating after a while by itself when I have the charger plugged in :s .. I think I might need to reflash with a stock Gingerbread ROM and take it from there .. What do you suggest?
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.
My device is N9005 with stock rom and Towelrooted.
Yesterday night my battery was at 48% so I charged it overnight. I got the notification that charging started. This morning I unplugged the charger, and when I picked up the phone about 1 hour later, I noticed that the battery level was at 86%, which is strange since it has only been on standby.
I checked battery usage and it shows 1 day and 14 hour on battery. this correspondents with the time I plugged in the charger last night.
I plugged in the charger again and notice that it start charging. In battery settings it shows 'charging' but it doesn't reset the timer instead the timer keeps running. The battery level also doesn't increase.
I have switched chargers, cleared cache and rebooted several times already, but no change.
I installed battery calibration, and the app shows that the battery level indeed increase, it went from 3800 mV to 4012 mV in about 30 minutes, but the percentage also doesn't increase and is identical to the stock battery indicator.
Is this a known bug or where should I look at my problem?
A reset would the medicine for your problem backup with titanium and go for it

Been there done that. Flashed the firmware again, same result.
Phone is at the service center now, so will know more in afternoon.
Howdy!
I think my battery is fooling me around.
Quick context:
- It's a Galaxy Tab 4, 10.1", model SM-T530.
- Android version 5.0.2.
- I received it at Chirstmas in December 2014. I barely used it until June (by that I mean maybe used it 5 times for 20 minutes). The point I'm making: I did not overwhelm or overuse it.
The problem:
I've just opened my eyes and realised some oddities... And since yesterday, I'm "actively investigating" my battery, reading a lot and "gathering data".
First thing, battery strangely draining:
Today when I switched on my Tablet, it was a 65%. I used it from 12:51 to 12:59 and it was then at 52%. I was just playing a game called "Final Fantasy Record Keeper" which does not seem to be too heavy (regarding the graphics). I put the Tablet to sleep by pressing the power button as usual.
Then I had to leave, 30 minutes after, I'm at my desk, I take out the Tablet and it's now at 42%. The tablet was in sleep mode all the time (I have a password so it wasn't possible to switch on and stay on).
I play some more and decide to use a stop watch. The battery drained from 42% to 15% really quickly, with on average around 30 seconds between each percent.
I put the Tablet to sleep again.
A couple of minutes after, I check and it's at 11%.
It takes me 30 seconds to get the cable and plug the charger. Before I plug the Tablet to the charger, I can see the battery percentage plummeting 9%... 5%... 4%... 3%... In a couple of seconds...
I plug the Tablet in.
3% to 5% in a glimpse, 8%, 9%...
Second thing, battery strangely charging:
After 1h09min, it's at 66%
After 1h44min, it's at 72%
After 2h15min, it's at 78%
After 2h46min, it's at 81%
After 3h20min, it's at 84%
After 3h39min, it's at 87%
After 4h09min, it's at 90%
After 4h21min, it's at 92%
After 5h10min, it's at 94%
After 5h18min, it's at 100%
As I don't use my Tablet often, just for hobbies, I generally just put to charge overnight and I never really checked the charging speed.
This is the first "set of data" I can provide, I will definitely look cautiously into that in the following days, hopefully under some insight from you.
Note:
I was all day with Wifi on. Even when it was charging. Everything else is off. And when I use it, the brightness of the screen is always on the lowest possible level.
Thank you very much for your first diagnosis!
Have a good day/night,
I also have that tablet but the 530nu variant and i have similar issues and even weirder i just shut it off as it was at 5% plugged it in and it said 0% charger on the powered down battery screen. Turned it back on not 2 minutes later and magically it was at 93%. Just to summarize it went from 0-93% in ,literally , 2 minutes of charging and while writting this and a few othet things, about 10 minutes since powered on its only dropped one percent. How do i access the system battery files? I am rooted so i can get into any file i want.

I have SM-335 and I have been trying to charge it for the last two days and all what I managed to achieve is 56% I have not been using it, mostly trying to get it fully charged. I noticed when checking the battery usage that WiFi was draining the battery, even when switched off to charge!!!! The other functions, like mobile network signal is constant and off when the tablet is off but WiFi bar is solid, even when the device was off. Charging is intermittent too although the cable was connected most of the time.... Next step I try is hard reset but this can't be the only solution
I had that problem on my t535. From 100 to 0 in 2-3 hours. Then when i turn it on after some time, it shows 1% but tablet works for about 5 hours on that 1%, or if i connect charger without turning on it shows 0% but when i turn tablet on it shows about 90%. I asked Samsung for new device, and i got it. Now is different story, my 6800mah battery charges in about 3:40-4 hours, and lasts about 9-10 hours(screen on time). I think thats hardware problem, because they wouldnt gave me new device if it was software problem.
I've owned my Note 4 since October 2014 and it's been working solidly since. Last Thursday, out of nowhere, I noticed that from a 14% charge, it suddenly dropped to 4%. I immediately scrambled for a charger and charged it back up to 100%. On Friday, I charged my battery normally again. Charging finished at 11 AM but the drain was abnormally high. My phone was warm to the touch and battery was dead in 4 hours. I was using the phone normally throughout that time, 4g on, location services/bt off, screen off for the most part. I ran OS monitor to see whether any app was locking up the CPU, but, as expected, the main CPU users were Android System and Android OS.
On Saturday, I charged the phone to full again, disconnected around 4 pm. Being that I was home, both wifi and 4g were off. Battery discharged normally, and was only down to 30% on Monday morning.
On Monday, I noticed that battery dropped from 21% straight to 11% straight to 4% in a few seconds. The drain from 4 to 3 to 2% was decent (few minutes of screen on time, on viber), then the phone shut off. I tried to charge the battery with the device powered off, but noticed that the phone simply stopped charging at 80%. I thought that was an abnormality. I tried wiping the system and app caches, but the problem persisted and drain still felt pretty fast. Tuesday night, the phone stopped charging at 91%, staying at the same level for 40 minutes before I gave up and unplugged.
My friend had purchased a fake OEM Note 4 battery and allowed me to try the drain/charge process using his battery to troubleshoot. When I first plugged his battery into my phone, the drain was high at about 1 percent per minute. When I tried to charge the battery, the charge level would not go beyond 90%. I switched on safe mode, but the battery did not charge any further either. I felt by then that something was definitely wrong with my phone. When I restarted the phone to get out of safe mode, though, it suddenly started charging again and hit 100%. With regular use, the fake battery gave me 16 hours of power, which I thought was relatively decent. Alas, when I started charging it again, it stopped charging at 77%. Battery Monitor Widget showed 0 mA flowing into the phone at the time, though the battery indicator in the status bar showed the lightning bolt.
I took out the fake battery and put in my original. It is now charging up normally, but I expect charging to stop before I hit 100%.
If anyone could provide possible explanations for what could be going on and/or other troubleshooting tips to try, I would really appreciate it. A factory reset would be my last recourse.
Thank you very much!
EDIT: My battery went all the way up to 100% this time. But it's the same one that got stuck (at 80% then at 91%) twice in the past.
I'm using two different Samsung chargers and different cords, by the way, and blew out the port with air prior to attempting to charge the fake battery that still stopped at 77%.
I had the same issue, took it to Samsung and they replaced the battery, it has been okay since that

Really? I was ready to write off my battery and just buy a replacement, but what was weird was that even the newish fake battery wouldn't charge fully. That's what made me worried that it's my phone that's the problem.
It'd be great if this could be as simple as a battery problem.
