I rooted my lg v10 and installed a custom rom. Immediately notice it was reading my battery % wrong. I tried to do some calibration got frustrated with it and just decided to go back to stock. When i went back to stock the problem still was there. I've tried letting the battery drain till the phone dies and charging it while it was off. Still reads it wrong even when the device is off and charging... Anyone got any ideas? Its not the battery because ive been able to go out with my phone and use it for hours on end while its at "15%"

So just the other day my phone would start randomly rebooting and it only seems to do it when the batter power is lower, like less than 50%. Ive been running the same rom (mikrunny 1.7) for well over a month and have had it oc'd the whole time to 1.5 and never had an issue before now.
It was doing it last night again. It was around 55% when it started. I left it turned off for a bit while we drove home from the bar and when I got home and rebooted it and now read 7%. Shut it back off and let it charge off over night. Booted up this morning and its now at 80% when it was definitely showing the green light saying it was fully charged.
So battery going bad or do I need to recalibrate it? Already ordered a HTC oem battery from amazon (it was 7.50, didnt realize they were so cheap!) so hopefully it is the battery and not something else.

Once you get your new battery it would be easy to see if the battery can be the issue. I have 3 batteries myself and I notice once that one of them was always causing my phone to random reboot. I color coded all 3 batteries to keep track of them and I notice that anytime the "red" battery was in the phone it would reboot while below the 50% mark.
I have replaced that battery and haven't had this issue, I'm rooted running a stock kernel and ROM so I could say that it may have relation to the battery.
I tried to get alogcat but nothing would show because the log would clear at boot. It can be a reaction to an inconsistency on the batteries voltage.
Are you on newest radio? I flashed the updated radio and started getting random reboot. I flashed back to radio 2.08, all reboots stopped.
I was having this problem with two separate ROMs until I reverted radio.

Hi All,
I have searched briefly but I cannot find this exact problem...
I have the S3 and I have had it since the begining of December 2012...I rooted and installed JB the first day I got it SO I cannot tell if it was me or if the phone was faulty.....but I have reverted back to Stock and the problem is still there.
Basically the phone does the following and it's starting to get to me.
*The phone charges to 100% but then it stays there untill I reboot and only then can i see the real battery percentage, it annoys me as I never really know what my battery is sitting at without rebooting.
*As the battery charge drops the phone will make a noise as if its connected to a charger and it will say its charging on the screen but the percentage still drops and this also won't go away until I reboot the phone.
I have tried the following and no success.
*went back to factory rom via KIES.
*fully charged the phone and then ran battery calibrator and removed the battery.bin file.
*inside clockworkmod I have resetted the battery stats.
*discharged batter completely....made sure that phone cannot even display the battery icon when attempting to switch it on.
*tried several roms
*tried several kernels *currently on YANK's 3.1 Aroma kernel.* (which is awesome by the way)
*left the battery outside the phone for half a day to see if that helps.
How come a simple reboot fixes the problem....which is why I'm logically thinking it's software related.... but I could be wrong.
Does the battery itself have a sensor inside that's reporting the incorrect information to the phone? aka charging when it's not?
Are there any other methods you guys can perhaps reccomend as I'm starting to pull my hear out
Does the battery itself have a sensor inside
Yes.
Try the usual answer and recalibrate your battery/ wipe battery stats . =Does not help .
Other option try different battery .

Hi, I flashed Paranoid yesterday. Installation went fine and I spent the evening customizing it to my liking. I put it on charge overnight and woke up to find it completely drained of battery. I immediately put it on charge thinking it must have slipped out or something. I left it for an hour or so, turned my phone on to find it was at 4%!! Then, even though it was still on charge, my battery started going down then died again.
I have even tried again to find it was no more than 4%. It seems to me that the ROM is somehow causing it but I can't even restore the stock ROM that is backed up with CWM as I can't get past 4% battery!
Any help at all would be appreciated! I can't even use my phone

I had a similar problem.
When I connected my phone to the charger it said 0% battery and the phone would immediately turn off when i plugged it out.
So I removed my battery, waited a minute, put it back in and turned it on to see that it was at 100%.
There's a bug in the battery stats I presume...
I've bin on this ROM and had no problems with it. Did you do a full wipe ? Sig is a bit messed up but its solid ROM. Like post before pull battery out then reinstall with all the wipes. How old is the battery?
RR 4.2.2
Hi.
After flashing a new ROM I could only charge my battery to 64% overnight.
The battery discharged to 23% in about 3 hours.
I installed battery calibration, ran it. The battery then charged to 57%.
This number is now stable even if I reset the battery calibration in CMW.
I think that the problem is that the OS has the voltage settings wrong.
At 57% the battery calibration program says it reads 3825mV. The EVO 3D battery is rated at 3.8V.
So it should be in principle fully charged, right? So why does it read 57%?
(Google play information for the battery calibration program claims that 100% is 4.2V, can it be overcharged that much?)
Do I just need to wait for the phone to settle? Or do I need to somehow let it know that the battery is 3.8V?
Anyone know how to fix this?
Really? Nobody else had this problem?
I have no idea how to fix this.
After the battery is discarged, it charges back to the right voltage 3.8-3.9V but it will read a random % value.
The OS calibrated itself over the weekend to where it would think the battery discharged over 2 hours from full.
Using the battery calibration program while in the OS seems to do nothing.
But resetting the battery calibration in recovery (CWM), or flashing a ROM seems to reset the battery %.
However! It resets to read 64% at full, not 100%.
With a fresh reset like this, the battery lasted me about 7hours (with me playing music for maybe one hour of that.)
When charged overnight, the battery topped at 43% for some reason. (Battery voltage still read 3.9V).
I reset the calibration in recovery and it jumped back to 64%.
I tried two different ROMS. I tried reflashing my hboot. I tried several versions of CWM. Same results.
Any suggestions from anyone? Please?
Edit:
I tried switching the recovery from ClockworkMod to 4ext, but it seems that 4ext did not work on my phone.
I was not able to boot into the recovery menu.
Edit 2:
I tried two different batteries. And I put back the stock recovery. Still wrong % reading.
I don't really want to put the stock hbood back in. Won't that relock my phone?
i have a solution

hi mate, i have an ISW12HT from AU KDDI just like you are and have same problem lf i flash custom rom like smooth criminal or CM 10.1.
finally i got the solution, just go to /system/bin , and swap/copy htcbatt file with htcbatt from stock rom AU KDDI
don't forget to change the permission to -rwxr-xr-x, then voilaaaa.... battery indicator back to normal again.
i hope that can help your problem...
sorry for my english
Ok so I have a galaxy s3 gt-i9300, which is about 20 months old, and it started to have this problem a month or so ago. The phone was running a kit Kat cyanogenmod rom, and it was draining the battery somewhat faster than the stock rom, and one day the screen started flickering at around 30% battery, which followed by the phone turning off itself. It can't be turned on until it's plugged in, and when I do so, the battery is at 0% charge, so I figured this was a battery problem and I replaced the battery for a new, original samsung battery. I thought this would make the trick. But I didn't, so my last thought was to return to stock software and this didn't solve the problem either. This always happens to me in every single charge at around 30%-40%. The rest of the charge lasts as long as expected, so the phone basically uses 60%-70% of a charge. I'm all ears for solutions to this and I also want to know what is causing it.
Try a battery from another phone, one that is known to be working correctly.
Else try a full wipe, including preload and internal sd, before you flash the latest stock rom for your country. Factory reset again in recovery after flash.
