I know this question has been asked in the past but there hasn't been any solutions that helped me. I recently installed the liquid smooth lollipop rom by fazevolv. I also installed his custom kernel along with it. I overclocked to 1.6 ghz. Everything seemed fine for a couple of days but then all of a sudden, the battery indicator showed that the battery was at 0%. The kindle booted up fine and it didn't turn off. It acted like the battery was just fine but didn't know the percentage of it.
I tried clearing battery stats, rebooting, clearing cache, draining the battery, fully charging the kindle, unplugged and plugged the battery, and I even went back to the stock rom and the kindle still shows the battery at 0%. Again, the battery seems fine and it can fully charge and it turns off whenever the battery is low so I don't know if it's a hardware or software problem. It's really weird... Also, when I go into kernel auditor it shows the voltage as 0mv and the level as 0 as well. I've never seen this problem before. Can someone please help me with this?

I'm not sure if this is a common problem or not but lately I've noticed that when I unplug my phone after it says 100% charged, it immediately drops to a lower number. At first it would stay between 97 and 99, but i have seen it go as low as 45. I've tried several things like not installing the ROM until it is fully charged, calibrating the battery, and a few others but nothing fixes it. Is it possible it's just a kernel glitch or hardware issue?

Thanks in advance all!

Its not a problem its a feature. The phone will stop charging when the battery gets to a certain temperature. So it will say 100% but it can go as low as 90%. I have no idea why your battery goes down to 45%...thats not normal. Try wiping battery stats from recovery or reinstall your rom.
I've had a similar situation. It helped to fully drain the battery until the phone shuts off.
Wait a while, then restart the phone without plugging in the charger. There should be enough charge to load the ROM.
Then plug in the charger and charge to a full charge.
If you are calibrating the battery, wipe the battery stats only after a full charge, and then be sure to run the battery down all the way before recharging.
2-3 cycles helps.
It's strange because the charge is shown accurately when the phone is off and plugged in. Like if it says 100% while the phone is on and I shut the phone off without removing the charger, it will show the actual amount the battery is charged on the battery meter. it's as if the kernel is having a problem reading the current battery state.
Thank you both for the advice though. I was very careful to install the rom with a full charge this time..or the base anyway..

It doesn't matter what the battery is at when you flash, the "flash at 100" rule is just a precaution to make sure your battery doesn't die mid flash. I flash as low as 20%
That is a well known bug with gingerbread...yes the feature stops charging at 100 and us let drain to 95 and then starts charging again, the bug is that it Bebe starts charging again at 95 it continues to drain, so even though it says charged as Dijon as you unplug it drops to the actual percentage.
it's really random, and not everyone sees it, and those who do can't replicate it consistently, thus no solid fix has been found.
Some have said turning wifi off while charging helps, some say turning it on...
Well that's a relief. You just saved me the tedious task of fully
Charging my phone before flashing back to froyo. Darky's 9.5 seemed a lot easier for daily operations than the reoriented gingerbread roms. I had to remap my softkeys for starters, and was having a lot of force close issues with apps I used a lot, the battery problem was just the most recent headache.
Thanks for all the help. Hopefully I'll have time to start learning development instead of wasting my time fixing my phone.

Hello guys,
I've messed around with OC etc. and I had to take out battery couple of times. After that some of my apps had reseted settings (probably sqlite db corruptions - it happens). Strange thing: after that my battery lasted for 2 days. Before that I was lucky if I got one day on one charge.
Latetly everything went back to normal and no more 2 days without charing.
I didnt installed anything new etc. Maybe market installed some updates - thats all.
Conclusion: something is f*cked up with our phone .;-)
I think it has to do with lg's battery drivers not working well. If you pull the battery (while the phone is running), on next boot the battery level is usually lower. I think that this causes the levels of the battery to be determined again. Normal shutdown looks like it's saving the battery level somewhere instead of determining each boot.
I've noticed one time after a nandroid restore the battery level was the same as when I did the backup. In this instance, I flashed a new rom to try for a couple of hours, then did a nandroid restore. If I remember correctly, it was about 55% when I did the backup, and about 25% just before the restore, afterwards it was back to 55%.
A while again I tried using this method (battery pull) to calibrate the battery. Using the pre #40 cm nightlies, you could boot without the battery in, using the usb charge. The method I used was to charge 100%, shutdown, remove battery, plug in to wall charge which booted the phone and inserted the battery during the bootup animation. After bootup, the battery level dropped to anywhere from about 95% to about 75%.
It certainly looks like to me that the battery isnt getting fully charged each time.
So maybe with your battery pulls you were actually recalibration you battery and getting a full charge, but after a couple of charges, it was back to normal ie not fully charged.
Hi all,
I will admit I have flashed the phone about 4 times in the past 2 weeks (different roms) due to other issues but now when the battery indicator shows 40% which is rite it shuts the phone down suddenly and says battery empty even though it still shows 40%!!! I can even plug the charger in and it will charge from 40% not 0. It did not used to do this.
This problem has affected 2 (cyanogen & stock LG!) of the 4 roms I have tried now so its not a rom issue and the phone was fully and properly formatted before flashing the new roms.
Even when booting back up it lasts a minute and does the same. Battery drain is not fast and all works fine until it goes below half.
I have wiped catche, battery stats & Dalvik catche many times when 100% charged but makes no difference.
Baseband is correct also.
I really need help as its unusable having 60% of the battery usable.
Anyone got any ideas before I sell it for parts ??
Thanks

do you have problems with battery before you installed anyone ROM?
and maybe isnt problem in ROM maybe battery making problem
Are you using the kernel that comes with each of the roms or are you using a custom kernel such as pengus' kowalski kernel? I know pengus implemented a new battery driver that has been known to cause other people similar problems.
So I've never had a problem with my battery at all. I easily got 6h of screen on time and everything was great.
Recently my Nook started to randomly shut off at around 20-30 %. It "popped" and it was off. Didn't reboot either. Like the battery was dead.
I would have to charge it again to be able to power it on.
Also the stats seemed to be off. The lockscreen sometimes told me it's fully charged and whenever I unplugged my Nook it wasn't fully charged. The battery LED also sometimes flashes green/red during charging.
I only get around 2-3 h of SOT at the moment.
I tried reflashing a couple of times (with full wipes) but the problem occured again.
So my question is: Are my battery stats messed up? Does it just stop charging at a certain point because it thinks it's fully charged but it isn't in reality?
Any ideas (on how to fix this)?

It's almost sure that you battery is degrading very fast. But its my advice to re-calibrate your battery. Set your screen brightness to max setting and leave it on until it shuts down. Now don't power it on. Leave it charging for around 2 and half hour.
Now install geekbench benchmark app and test your battery.
If you heard a pop noise, the battery probably delaminated/micro-exploded. (Li-Ion's tend to swell and fail from the heat of (over)charging.)
There's a company, newpower99.com, who has a YouTube video on replacing the battery in the HD+. The battery sold for $25 US last year, but now that our batteries are beginning to degrade, they're out of stock.
I found another site selling replacement batteries for $80. (portatronics.com)
I've noticed that my screen-on time has dropped from 6 hous to 5.5. Maybe the Nokia N1 will be available and rooted by the time I hit 3 hours.

I'm having the same issues, and reading this reminded me of trying BatteryCalibration to reset the battery since my nook HD+ stock OS is rooted.
I had this problem several times before I installed CM. Usually, it happened when there was an update available, and when the Nook started to update, it factory reset itself.

I havent installed a custom ROM in a while so I was feeling bored and downloaded a new ROM, copied the files overs and booted to TWRP recovery and wiped everything. I cant remember what all but i think whatever was available to wipe, I wiped
I then installed ADB to my new PC and my phone was not showing up in fastboot or adb (possible driver issues) and eventually the battery died while in the recovery.
I plugged the phone into the charger and it kept showing the battery empty icon and was not charging at all. I left it on charge for hours but nothing happened.
I eventually got a new battery and while the battery still had life in it I charged it full and then went on to install a ROM from my old PC that already had adb and I used to use it previously for installing custom ROMS.
No the phone works but dies randomly at different battery percentages. Sometimes at 60% othertimes at 40% etc..
Battery drain doesnt seem too bad. When I disable wifi, bluetooth and NFC the battery only drains 50% after 24 hours but if I leave wifi on it drains faster.
When I try to play games at 100% battery after 30 minutes the battery would be at 75% and then just shutdown saying 0%.
Then I plug it into the charger and while the phone is off it'll start charging from 0% and when it reaches 25%, if I turn it on it shows 70%
Could I have deleted / wiped files that I was not suppose to that could cause this kind of a problem?

Try to make a clean ROM installation with prior the fw and formating data with yes.....
Follow installation instructions of the chosen ROM step by step and don't delete everything again except with format data yes
Did you say you installed a new battery? Was it from official service center? You can use some battery monitoring apps like Better Battery stats /GSAM etc and see what's really causing it. Otherwise fresh install, check for few days.
So you got a new battery as a replacement. If you just got this online then there's a high chance the battery is a scam and is not exactly 5020 mAh. I know this because I'm a victim of this too on my older phone, I literally have the same issue. I suggest to get a new replacement, making sure to get it from official Mi Store or service center. In the meantime, calibrate your battery by emptying to 0% (till the phone dies) then charge to 100% while off. Repeat a couple of times and the battery percentage should display correctly. There's also a suggestion of clearing batterybin stats or similar to Poco x3 Pro where you calibrate PMIC, no harm in trying because I tried it before too and it didn't seem to cause any issues.
Here's a link to the guide if you're interested:
Calibration of the PMIC (Vayu/Bhima/Surya) via fastboot.
⚠️HONESTLY READ THIS WARNING ONCE! - CALIBRATION OF THE IC, WOULD NEITHER RESULT IN A HARD BRICK/PREVENT BRICK. AS TO BE CLEAR WITH THIS *HOW TO THREAD*, IS ONLY MENT FOR PEOPLE HAVING PARTIALLY BUGGY PMIC, FACING AFOREMENTIONED ISSUES, HAVING...

But the same issue happened on the original battery also
"I cant remember what all but i think whatever was available to wipe, I wiped"
So you wiped internal storage? That's probably causing issues.
Yep I think I did or at least some of it idk.. Can that be fixed?
Re-flash Stock ROM.
BTW: Always use Android USB drivers provided by phone's OEM, not those found in Android platform SDK. Then phone should get detected via USB.
