Hello,
I had to get my N7 replaced yesterday due to a screen fault. The new oine seems fine. I took it out the box, tried charging it for a few hours but nothing happened, I still got the flashing light where the USB port is so I swapped chargers with a relative and it worked fine (new charger needed straight out the box, great)
It charged fine, I switched it on about 50% just to check the status then switched it back off again. So once fully charged I turned it on and restored my apps using Helium etc and got it back to how I like it. I l;eft it ion overnight and the battery had gone down a staggering 30-40%. When I looked at the battery usage it says that the screen time only accounted for 9% of the battery and that "Android System" was 36% of the issue.
On the last tablet I the Screen used to be the most juice hungry feature of my batteries usage so what's changed?
I have not yet upgraded to 4.4 because I want to get this sorted before I change anything. I don't understand why Android System takes up SO much more battery when absolutely everything else is the same?
Thanks

I bought a new battery for my g1. Somehow, when i charge it fully after only 2 hours there is only 50 percent left even though this whole time the phone is not used at all. I have checked the battery usage and it shows that the most of it is used by android OS. when i was using the old battery everything was pretty much normal. Does anybody have an idea if this battery is defective or it's an OS problem or anything else... I've checked the spare parts battery history (other usage) and it says that 99.9 percent of the time after I unplugged it was running without sleeping even though there were no apps running and I wasn't using it at all. I don't use any widgets too and there are no unusual new things in the process list. The battery health is said to be good. What might be the problem?
Have you run the Battery Status wipe?
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!
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.
My Moto x pure edition has picked up a little quirk. It shuts down for no apparent reason under really light use, like scrolling between screens. It always seems to happen right around 30% battery level. After it shuts down, a reboot gets to the logon screen and then it dies. I can do that a couple of times and the same thing happens. If I plug it into a charger it shows zero battery but it will boot and I can log in. The funny thing is after logging in the battery shows 30% remaining on the android battery meter and it works fine without the charger. Seems to discharge normally from this point. This has happened about 5 times in the last couple of weeks. In summary the same thing happens every time: Shuts down at about 30% battery, won't log in without the charger, shows dead battery when charger is plugged in, after logging on the battery shows 30% charge, normal battery life for the remaining 30%. I am thinking something battery related but battery life is not too bad.
Particulars:
Moto x Pure ed
xt1575
Original battery, about 2.5 years old, battery life is on the decline but still ok.
Android 7.0
Stock Android not even rooted.
Running on Verizon soon to be T-Mobile.
Any Ideas? This has been a really great phone and I am not quite ready to walk away. I would buy another tomorrow if it was available new.
Thanks any help
John
That means your battery is getting old and can't provide enough charge for some heavy operations. I would suggest you to get the battery replaced.
I hope not. My experience is the available aftermarket batteries are junk. Not worth the effort. I noticed there was a battery thread, I will take a look at it and see if there is a solid battery available.
Thanks
John
Mine recently started dying at around 35%, chalking it up to old/depleted battery....plug it in, it powers on showing 35%.....I'm going to ride it out until op6 (possibly pixel xl 3).
This has been happening to me for about a month now, except there is no approximate battery level that it occurs. Most recently, I pulled it off the charger to take a photo, and it just shut down. Held the power button down and it showed the battery at 0%. I then reconnected the power cable, and it showed 95%, so I tried to power it back on and it bootlooped. Tried again and everything was fine. Unplugged it and tried rebooting it and as soon as it was finished, it shut down. Plugged it back in and let it sit powered off for ten minutes, unplugged it and it's been working ever since. But, this will occur at any given time and has made the phone too unreliable for daily use, so I had to go back to my S4 until I can get this figured out. Such a bummer, because I've gotten really used to that big screen and not having to wear 'cheaters'...lol
Ok, seems like it is not a completely unique prob. I have a battery on order. I will see if the swap fixes it. Thanks for the help.
Did you get any solution? Mine started shutting down @ < 50% when I start video app
Use a battery voltage monitoring app like 3C battery monitor and see if the voltage floats around too much, if it does then it's dead.

That's where I brought my battery when it was starting to die.
Hey guys,
today my phone just didn't show any other battery capacity than 50%. I had it on my car dash charger for multiple hours. This evening it still turned off and showed the "Battery too low" screen, so I assume it did not charge.
First, TWRP also showed 50% and a very long weird number as CPU (top left), then it stopped showing anything about the battery
After I turned it off and tried to charge it, it crashed in the bootlogo and rebooted.
Any ideas what to do? I already reflashed the firmware.
Best regards
Colin
I have this problem too
Just use it till it gets fully drained then charge it?fully
Currently encountering the same issue with my OP5 now and when I consulted a tech regarding this one, he informed me that it may be a possible motherboard or battery issue. Will have my OP repaired by early January and hoping that it's only a battery issue(fingers crossed).

Looks like you drained the battery too much and the battery chip got confused. Or worse, one of the cells died. This doesn't just happen to OP5, but to all batteries.
There are a few options:
Replace the battery: https://www.ifixit.com/Guide/OnePlus+5+Battery++Replacement/103028
Turn off the phone, then charge it fully while off. Then slowly drain the battery again, in a way where the phone isn't sleeping so Android can gather battery statistics.
If above didn't work, then do above method, but also clear battery statistics in TWRP, or the recovery of your choice.
There's the option of putting it in a vacuum sealed bag, and putting it in the freezer. Google for details, and do's & dont's.
Hope this helps!
Did you get the issue fixed? Currently I'm also having the same problem
