Something is wrong with my battery meter

this morning it was 100% and when i got home it was at 87% but after i did a soft reset it said 15% i did another resent and now its at 45%, i cant get it to read the batter correctly anymore?
charged for AROUND AN HOUR and how it says 100%

i am having the same problem after MR2. it was abt 56% after a soft reset(Phone was really slow kind of hanged) wend to 15% and another soft reset back to 54%. some bug i guess

http://forum.xda-developers.com/showthread.php?t=682270
it seams that it is some bug but no one has found yet an solution..

come on guys, too focus on how bad the x2 is and forgot about the basic problems.. has anyone come to mind it might be the battery?? i had that problem too thinking i have overcharge the battery so when out and buy a new one now its all sweet.. and send the old one back SE they gave me a new one.

well hard to say but it is from the start-brand new battery and from the beginig..li-polymer battery are hard to overcharge-they can be charged even if they have 70% or 80% power still in it...but l have confirmed in Serbia several cases of battery issue-so are they all "overcharged"?

ive had at least a dozen mobile phones over the last decade and ive found with practically every one of them that if you do a reset or turn the phone off the battery meter will drop. this is nothing new and not specific to the X2 or even sony (ive had nokias and philips phones do it). i dont know if its because it takes extra grunt to restart the phone or it loses calibration or what. the battery meter guesses the percentage of power based on the voltage so its not an exact reading anyway. ive found that popping it on charge for a bit seems to sort it all out again.

it never happens to any of my phones. I mean sure, it drops by about 5 percent but that's if I am updating on the phone.

not that it wont stop charging, its just the meter changes erratically with no reason, frim 90 to 4 back to like 50 just from a soft reset

but now how to stop charging?
when my phone is turn on and connected to a wall charger,then charger charge the battery to 100%..and that is that..but it still charging. when phone is off and connected on charger,then it charge to 98%..that is what it shows when i turn on the x2. l have tried battery calibration procedure and nothing..

I noticed this happened on MR1 when removing and replacing the battery (as we all needed to do soooo many times ). Something must be happening with the contacts. I just made sure they were clean and reinserted my battery and haven't had a problem since.

has anyone noticed that when you charge the battery
when the phone is switched off, that the battery does not stop charging? the big battery icon keeps going up an down even if you leave it charging all night? the icon is still showing charge..

i can confirm that too.

My previouse post is a guidline for charging.
With Li-Po's if you over charge them they discharge, this is a well know fact for RC cars/planes that run Li-Po's which is why they have charges with so many settings to get optimal performance and warnings and cut off when fully charged if the cut off/discharge does not take place it makes the Li-Moss (dendrites) unstable, when they get long enough they can short out the battery and cue explosion
When on charge for a long period have you noticed that the battery gets rather hot, and after 30/40 mins it is cool again?? this is because it has been over charged and is discharging to stop it from exploding. it also explains why even tho its been on charged all night its only at %60 odd because the discharge has taken place.
and i have just been told by a work friend that HP are doing a re-call because of the above.

All this you provide is ok,but problem was from the start-brand new phones were bought and from start this happens..so SE sold us defect battery? Funny, but there is no point to talk about over heat and overcharge when simple..battery icon large one when phone is off do not stop or go off display few people tried 9-12h and it still is there. Battery is no hot..it is hot after 2h-little hot..after that phone is cold. l believe that something is wrong with registry keys for charge time..l am not a programmer or developer but l dont think that we all fu*** up our batteries ..this is not a first phone to us..so we are not amateurs in usage of battery charge.

i dont understand.. why would you turn off the phone to charge it? it does appear there is still an error but this isnt necessary and wont charge the phone any faster or more efficiently.

Some times l do not want to be disturbed and if battery is low l turn off the phone...and plug it to charge... obviously there are no body who thinks that this bug is annoying.
This is my first device with such a bug,and because l deal with mobiles(l had over 100 devices and use them form last 10 years) never cross to such a issue..and nobody know how to solve this bug.

Weird Battery Drain From 60 to 3 after reboot?

For the last couple of days after i reboot my phone i suddenly have 3percent battery when b4 i rebooted it i had 60?
WTF??
Anyone else see this or is there a solution?

I've had similar issues after rebooting, particularly after doing something resource intensive like flashing or running a full backup. I think it's caused by a defect in the battery and plan on having Sprint replace my battery.

I had this issue twice already. I was not sure what the cause was. I believe it is a horrible battery bug.

I have this issue to. I went from 46 to 13. I also noticed that the battery meter in the staus bar seems off. While batt stat and gauge say i have 50% the meter looks if i have 80%

I was able to reproduce this bug fairly easily by rebooting while the phone is on the AC Charger while it's really low. I turned it back on and it went to like 50% when it really was at 10%. I unplugged it from the AC and then "Shutdown" not reboot. Turned it back on and it went back to 10%. Yeah just seems like a battery bug.

You dont actually lose that battery life, your phone just doesn't display it correctly. I bet you will be @ 3% for a loooooong time, also if you charge your phone, it will charge a lot faster than normal untill you reach 60% again.

Power related issue

I'm finding that sometimes when I plug in the tablet to charge even if they battery is almost full, as soon as I plug it in it will think the battery is at 0% and start shutting down.
When I power it on and look at the battery stats it shows that the battery went to zero and then goes back up to were it was before the shutdown.
Also another issue is that the battery status will say its not charging even though it's not plugged in and the level never goes down even after a reboot. I find to fix it I need to go into a custom recovery and reset the battery stats for it to return to normal for a few hours.
I'm running on the stock image.
Its annoying, but I'm hoping that the next update will fix this.

Can't say I've ever experienced such an issue, on any device. If your looking for a fix, perhaps reflashing the factory image completely might help (I don't understand the battery stats file too much, but I would think a reflash would probably replace that file, and fix the problem).

I thought I was the only one with these problems. Never had these issues on my Galaxy Nexus. Now on the N10 I have the first problem you mentioned + battery % not moving until I reboot the unit (Random). Very annoying...I called Google Play support and after doing some test told me that they'll send my a new unit.
Note: I've flashed the Google image and I still had the issue (seems less frequent)...Sometimes I can have the % correctly refreshed and sometimes it stops after a few minutes.
I've attached screenshots of the problems...(1st image) Long straight lines were when I was actually using the device!! Cut in graph = reboot
Second image: both problems, check out the spike a 0%!! when plugging usb cable

I have the same issue and my replacement is on it's way.

So I called support and I'm getting a replacement device.

I've been searching everywhere, thanks to this thread now I know I'm not the only one having these exact same issues. Looks like I'll be making a call to Google Support

Probably a software issue to be addressed in a later update.

Are these issues still present on the replacement devices?

So far not happened on my replacement device. Went from 70% to almost 10%. Still testing. Also wakeup time is normal. I think it was hardware related.
EDIT: on my 3rd day and this new device always correctly reports battery life. Definitely hardware.

I'm having the exact same issue with battery % not updating at random times and then sometimes the n10 claims 0% battery after recharging overnight and promptly turns itself off. Did the replacement unit fix this for you?

Yes my replacement unit is perfect. On my fourth day now and no issues whatsoever. My first unit was doing it day 1.

I got my replacement unit 4 days ago and the problem is definitely gone! On my first device it also happened since day one.

My Nexus 10 just started doing this after a reboot last night, I guess I'll have to ring support and get a replacement.
I'm running a custom kernel, recovery and unlocked bootloader. Do I have to flash back to complete stock before I send it in?
Cheers guys

I'm not sure if I have this issue, but my N10 is definitely acting strange.. I put it in my bag this morning on 42% charge and when I took it out in the afternoon it was dead (I thought I might have hit it to something and damaged it), but when I plugged it in it started to charge after a few minutes from 0%. Then it rebooted after like 5 minutes without me touching it and it's charging for now. The battery stats don't show a drop to 0%, the graph ends at 42..
I've had this device for around 3 months now and never encountered this issue before, so I'm not sure if it's really a hardware issue, but I'd be quite disappointed if I had to get a replacement as this one is a really good one in terms of the other common issues (bleed, throttling, creak).

[Q] [AOSP] Official 4.4 - S4 Google Edition - v6.0-OTA - Feel the Experience of Nexus

Hello to all!
Since I don't have honor to post on main development page I need to post here in question!
I can't find nowhere something about battery life, I installed without problem ROM on my SIV and battery life is very poor. Yesterday I watched on YouTube MKBHD Hangout with Motorola CEO Dennis Woodside which have length of 39 minutes I think. My battery was at star 98% and at the time of ending video vas 45%. Battery can't last full day of normal usage. (it last from 07:00 to 18:00). At beginning I noticed this problem and I installed One Power Guard and its always on powersave or standby mode.
This anyone facing with this problem?

Yes mine is exactly the same. Running v4.0 and battery life is terrible now. Camera app force closes every now and then and sometimes maybe twice a week it reboots.
Plus I can't charge it switched off - everytime I plug it in it starts up.

Hi,
My battery is a little poor too, but it was because I was with my cellphone screen on almost the whole day... When it was an extreme case (when I was in 4.3 AOSP ROM and it didn't last even some hours, like you), I recalibrated it (I used to do it with my Xoom and X10 Mini Pro, it may be a placebo, but looks like it worked...
To recalibrate simply let your battery run completely out, then plug to the charger and let it charger completely while turned off (the white battery icon appears), then turn it on and let it run out again, then charge fully again. Remember that plugging and unplugging your device from the charger is bad for your battery, and remember to keep the screen brightness very low, turn off WiFi, Bluetooth and SPECIALLY 3G when you're not using.
Hope this helps,
~Lord

You need to flash v.6.0 which mostly correct FC camera app. I notec when i was runinng on ART reboots was more common.
My solution was to flash MK9 stock rom, this is the most stable and reliably by me so far.

Thank you for advice. I was using battery calibration on my Galaxy SI GT-i9000 and Xperia X8 and it was uselles. Know i didn't se enyware that i need to recalibrate battery so i didnt do that.

Battery Issue With Camera Related Apps

Okay, so I've heard about the battery issues going around with the 6P's but I think I've got one that's a little different. My battery has typically been completely fine. It dies around the usual 0-1% and maybe some times 2-3%. However, whenever I use my camera app or Snapchat (which makes me believe it's related to camera apps specifically) my phone will die if the percentage is about 24% or less. I could be at 20% completely fine, but then go into Snapchat and it'll die a few seconds later. I plug it into the charger and turn it on, and it resumes with the same battery percentage. (If it dies at 20% it'll resume at 20%)
This happened on both marshmallow and on nougat. Has survived countless flashes. I've used custom Roms and have flashed stock over again. Not in attempts to fix the problem, just for fun.
Anyone have any ideas of what's going on or experience something similar?

Huh, you know what? I actually haven't. I'll give it a shot to see what they say. I was thinking I've tried everything shirt of replacing the battery (which I don't think would fix it). Can't believe I didn't think about calling. Thanks. Hopefully they've got a fix, but if not there are worse problems to have

Google support is great don't worry about it

Its a known issue, couple other threads on it
