I seem to be having problems with the way my nexus is reading its battery capacity. Pretty frequently now the 15% battery warning comes up, and a couple minutes later it's buzzing in my pocket to tell me it's at 5% or powering down, when it couldn't possibly have used up all that battery power in that time.
I also have issues where sometimes I plug it into my charger and in a few minutes it already says 100%/fully charged, then when I unplug it it reverts to 30 or 40%. In general the phone seems to have problems with telling what its actual battery level is. Has anyone encountered a problem like this, and have a suggestion of how to fix it (short of a factory reset)?

Hey all,
This is my first post ever, but I've been reading up on battery issues and some of the "interesting" fixes that people have come up with including radio mode switching and charge cycling when on/off.
While playing around with these charging methods I have consistently found that when I charge with my phone off the LED will turn green but when I turn the phone back on and continue using it, the available battery drops approximately 10% within the first hour (which is a free-fall for how conservative I have the rest of my settings.)
Conversely, when I charge with the phone on to 100% then disconnect, the battery maybe drops a % an hour with the same usage/settings.
2 questions:
1. Has anyone else noticed this?
2. Has anyone gone through different modes/usages (standby, slacker streaming, wifi streaming vs 3G/4G streaming? and so on and so forth) for a few hours and noted battery drain?
Just gets me wondering (like in the HTC battery fix post) how much of this is issues with clearing battery cache after flashing various things or batteries just not topping off correctly as mentioned previously.
Yes, I read somewhere on here that once the EVO hits 100% charge, it stops charging and doesn't start charging again until it's under 90%... so if you unplug it somewhere in between there, it will drop to that point quickly. But for some reason, the display will always show 100%

Yeah, I remember reading that too, but I thought that only happens when the phone is allowed to sit idle and the battery slowly runs down. This was maybe 5 minutes within charging the phone to completion (while off) then repowering it back up and checking things out. I sure hope these things don't discharge that rapidly when turned off.
Hello all,
Having some strange issues with the battery level reading on my Xoom. I plugged it in yesterday after it died and was startled to notice that 15 minutes later it was reading 46%. I unplugged it, played with it for a while, and the meter seemed to be behaving normally, so when it got to about 40% I plugged it back in.
Now it's at 100%. It has been there for about 12 hours now including about 2 hours of use. Plugging it back in briefly while turned off, the LED indicator took the normal amount of time to show fully charged, so I don't think it's an issue with the battery itself. It generally takes me a few days to run my Xoom down completely, so I thought I would ask... has anyone experienced this before, and did it resolve itself after a full battery cycle?
Also, if it doesn't start reporting correctly on its own, what options do I have other than installing CWR and wiping battery stats? I've left it stock so far and I'd prefer to keep it that way.
Hello there,
So, I had my phones screen repaired a few weeks ago. For the last two 2 weeks or so, after the phone loses about 30% charge it will start losing signal and then regaining it and this will occur for about 5 mins and then the phone will shut down weather its at 15% or 70%.
After this, everytime I reboot the phone it will turn off within 20 seconds even though it will still have plenty of charge on it. However, It is a dirty shut down. It won't say phone is shutting down, it will just turn off instantly
The only way to solve it is to charge the phone. It will say it still has charge once I put it on charge and that the battery is not fully drained and once it reaches a high enough percentage (e.g 80%). I will be able to use the phone till it drops round about another 30% and the cycle will begin again.
I have tried switching to multiple ROMs and wiping everything of course so it must be a hardware issue. Do you think it is a dodgy battery? Or what could be causing this issue? Any help would be greatly appreciated
Thank you

hi frnd,
i think its a battery issue. get it changed and everything will be fine...
Thanks & Regards
Hi there, I currently have a Samsung Note 4 running CM12.1 and in the past two days the phone has randomly "crashed" late afternoon/night (5.30pm today and 8.40pm last night). My phone performs fine throughout the day and then I'll notice that the screen doesn't wake up if I press the home button like normal. If I then power the phone on it boots up and instantly powers off after booting since it has "0%" battery. Both times the phone had plenty of charge in it, around 30-50%. Has anyone else encountered this before?
I have some screenshots but I am unable to post the Imgur links in my post because of my post count. Any other way I can post them?
Specs:
SM-N910F
CM 12.1-20151022-NIGHTLY-trltexx
Android 5.1.1
I can provide more specs if you wish.
Buy another battery, if another battery is OK then your old battery is broken
I had a similar issue where it would, after a clean software reset, shut down unexpectedly at 20% or so - then subsequently at 40%, 60%, and further 20 percent increments when I'd let it shut down of it's own accord. RMA'd it under warranty, pretty pleased with the service I got. No software fix for it.

Recalibrate your battery. I had this issue, too, after flashing another ROM. My Note 4 would shut down and die at ~50%.
1. Download Battery Calibration from Google Play
2. Fully charge your phone. By "fully" I mean not only to 100% (which, in your case, will be something like 50% effective charge), but until your LED has turned green. For good measure, just turn your phone off and let it charge overnight.
3. Run Battery Calibration, and tap the big button that says "Battery Calibration"
4. That's it.
You should do this every time you flash a new ROM, because there's always a chance your battery gets miscalibrated during the process.
Thank you very much for your help everyone, I'll try the Battery Calibration and let you know if it fixes it!
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?
