This seems to be quite a common and somewhat obscure at the same time.
Many people have reported installing a new rom or even just powering up their phone and seeing a battery % much different from what they expect. Most often much lower than it should be. Evidently this corrects itself after some time but it's a real problem if your display reads <15% because you really have to plug it in then, even with you know you have 90% battery!
So, here's the solution after testing it under different circumstances over a few days:
Simply boot your phone when it is not plugged in to a power source and battery % will be accurate.
That simple. Silly LG!
So, if you flash a new rom, unplug the USB cable before you reboot...

hehehe jups allready figured that out on myself tho haha. But indeed that's kinda silly of LG

What about every time I use a custom rom the battery % indicator jumps right down to 90-95% when unplugging from charger ? Do you have a solution for that ?

Sorry to say the same..
Even while charging with the phone shut down, pulling it off the charger and then booting this happens. On my phone I have experienced it on all MCR's.
It's really not a big deal as long as the battery performs as Stock 10b, that build has been stable batterywise on my phone. But staying stock isn't too much fun
Well, every time I charge, whether I reboot/shut down before unplugging or not, my charge always maxes out at 96%.
Annoying and I'd like it sorted if at all possible.
Anyone?..........lol

ye i got that exact same issue i was wondering why that was happening and hoped that a simple reboot would fix it but its a bit more complicated than that i suppose...
also the battery reset in cwm didnt fix the loading till 97% w/e percentage.
when i install the stock rom it allows me to load it till 100% though pretty weird stuff -.-

I had a replacement netbook battery that could only max to 90%. So, over the weekend, I practically drained it to 0% (not a healthy practice for Li-ion batteries but I was desperate). Took out the battery for a while, and then recharged for several hours. Well, it seems to get up to 100% now.
Perhaps you could try using the the phone until it very low on battery before recharging. Maybe the charging process in the phone needs some sort of recalibration. But should not be doing this all the time as it will reduce Li-ion battery longevity.
Let mine totally die last night so it wouldn't even turn on at all. Took out and replaced battery and then charged it overnight and hey-presto, when I unplugged it this morning, it stayed at 100%.
Solved indeed....for me anyway. Feel free to try the same and post your results.

I'll be sure to try your tip man. But not easy drain it completely when I always need the phone :=)
I guys! I've got the same problem.
I think that it could depend on the "full battery popup FIX" that Paul introduced in his roms by the FR8.
So I would like to ask Paul if you can create a patch to remove that fix. Just to try it!
According to me, incorrect battery amount depend on a wrong voltage read error (offset introduced?) by the rom. :blink:
In my case, I have followed many times battery wype procedure without positive issue. The matter leaves only by flashing original roms.
I think that if Paul have written a wrong battery values range (to delete the battery full popup) that can be traduced in an incorrect battery status displays.

Perhaps, but you can not conclude it was introduced by MCR. You logic is wrong there.
Even without "battery full popup fix" it doesn't work good...
Battery level, when unpluged, stay at 100% for 2 minutes afterwards drop down fast until 85% then drain normally...
I'm getting huge battery display problems no matter what I do.
When I took it off the charger this morning, it said I had 100%... thats fair enough. However it stayed at 100% all day, so to "refresh" it this evening I restarted the phone, and low and behold it now says I have 27% left. But again, it's just sticking at that value, even with me now plugging the phone into the wall to charge. It simply says "Charging (27%)" and won't budge, likely until I restart the phone again.
Sometimes it works fine, it seemed to be doing ok last night before I put it on the charger. Any tips/suggestions? Is this something likely to be fixed when the Gingerbread update rolls around?
This is my first real smartphone, and am fairly annoyed as its giving me a fair few problems that I've not had from other electronic devices.
As I stated in another thread, I had the same issue while on MoDaCo Fr12. However, after reverting back to stock, the battery percentage is spot-on and I'm getting up to 48 hours use out of it.
Draw your own conclusions.

That sounds super, but I'm still on stock too. About the only things of note I've done are root and switching to Launcher Pro. Oh, and Clockwork Mod of course. Perhaps a complete reboot is needed, we'll see how it goes.
Saying that - since charging, my phone has been at 90% all evening, until right this moment when it changed to 89%. It's less than I'd expect on this type of phone for 3-4 hours use (or lack thereof, I've barely touched it), but it's a start eh?
Welcome to the world of smartphones my friend. I've had various handsets over the last 4 years from iphone to android and a day and a half out of the battery is about average......at best. ;-)
Sent from my LG-P990 using XDA App
Just to clarify, what I meant in my previous post was that I was expecting to battery to drop a lot more than it did. The fact that it only went down 1% in several hours of use prompted me to think that the battery value was messed up.
As it is, I've not charged my phone in the 36 hours since, and it tells me I have 73% battery left. Perhaps it is performing extremely well after all? If that's the case then I'm more than happy with it, but being the pessimist I'm still expecting the phone to turn off sometime with the battery reporting incorrect values.

I noticed, a few others, but should be minority has the same problem as mine.
My N1 powers off itself when my battery shows around 15% or so.. sometimes 17% sometimes 14%, never lower than 10%.
I already tried to wipe battery data at recovery or deleting the battstat.bin file etc etc but it is still like that.
Is there a solution for this and any reason for this?
Majority of people's phone only power downs below 5%.
Many thanks

My phone turns off at around 19% now after I played with the battery calibrator app. (I set the life at 100%, was lazy to run the full cycle calibration)
Its powerful and probably can fix your problem.

He said he was too lazy to complete the learn cycle, which is part of the calibration technique. There is no sense in trying to pick "pieces" of the process and hope they work, they won't. Start with step 1 and follow the directions to the letter, don't skip anything. I would suggest reading the instructions a couple of times prior to starting and ask questions in the thread if you aren't sure. There are several of us that monitor the thread and will respond quickly...myself during US daylight hours and Temasek in the evening (he's in asia, I think).

Thanks. Wish there was a quicker/easier way.
I'm currently testing a direct way using simple math:
If 1452mAh is 100% how much is 19% ?
i.e. 1452/100*19 = 275mAh (for me)
I've set "full40" to 1452-275= 1177 (the calibrator app's minimum is 1200 so I just set it to that.)

That may work as a guess-timate, but the stock battery comes rated at 1452mAh and stock age is set to 94%, so you would really be setting to 1128mAh unless you reset age to 100%. It really doesn't take that long to set up the application for learn mode...just a few minutes. It does take 31/2-4 hrs to fully charge the phone and complete learn mode if you set the min. charge current to <20mA. To speed things up, just set it to <40mA as you won't miss the little bit of extra juice.

hmmm good point, i never thought of that lower limit. we'll see if we can update the app.
but to answer this thread's question, the age register in your phone is now out of whack, and you need to set it accordinly to allow the battery to go down to 0%. the learn cycle determine's the proper "age" value and sets it accordingly.
you could also guess an age value, say 83%, would be close. but really there's no reason to not do the learn cycle and figure it out.
BTW all these values are stored in your battery's chip, and it needs to be updated to new value.
Quick question:
1) Sometimes even after I turned on the "Detect Learn Mode" my Current occassionally dropped below -200mA (e.g. 160mA) for a quick while... will it affect the result?
2) "Turn off" means turning off the Detect Learn Mode right?
3) where can I see the "Charging current"? Capa.?
Thanks
What if I rotate among three different batteries on a regular basis? I have an external battery charger too. Will the calibration be in any way useful or will it get confused by the changes?
I have my original January 2010 battery, a December 2011 replacement from HTC, and a MOMAX battery that also holds up a pretty good charge.

you can rotate batteries no problem. when you do a learn cycle, the age value gets written to the chip inside the individual battery. so you can swap batteries no problem. just make sure that the correct age value shows up when you swap, cause sometimes the age resets when removed from the phone. just set it manually back to your proper age if so.
we were trying to add "profiles" support to the app so you could swap batterys and it remembers the parameters for each and sets them accordingly when you swap the battery. but i dont know how long that will take...
Okay good to know. I bought this charger:
http://www.amazon.com/PowerGen-Mult...CAT6/ref=sr_1_3?ie=UTF8&qid=1295658169&sr=8-3
And it's pretty neat because I can just position the pins myself to charge any battery I want. I've tried it with camera batteries, Huawei U1250, Moto Milestone and RAZR, and Nexus One batteries. It works really well and it's somewhat future-proof because it will probably work with my next phone's batteries too =)
Okay, this thread is probably misleading. This could be a bug, nothing more.
When I complete a build and then push it over the USB I have noticed something funny.
If I keep the cord attached when I flash, when the nook finishes booting, my battery gets reported as 100%. I can't say for sure that it happens everytime, but nt happens pretty often, at least.
It's pretty hard to tell, but it really seems to get 100% charged. The battery doesn't seem to drain any faster.
Now, I haven't checked it with any serious discipline. Maybe the nook would just shut off at 30% or whatever. Maybe it just reads the percentage it was at previously as 100% at this instance. Maybe its hard to tell if the nook just drains 15% faster. Maybe who knows what.
But its happened several times, and it sure seems to be 100%. I've checked all the levels in Battery Monitor Widget. (Science!)
So what do you think? Did my nook develop cold fusion or did I discover a misleading bug?
You can see the voltage jump in the attached screenshot. It jumped from about 80% to 100% in maybe ten minutes. I've seen jumps much more extreme.
I've had it happen to me too when I connect my nook to the pc with the usb cable. It will only jump to 100% if the battery level (for me) is above 80% when I connected it. Cold fusion, man I wouldn't be surprised with everything that's been done to it. I found when you reboot right after it jumps to 100%, it will drop back down to to what it was.
Yeah, mine maintains the charge level after reboot. At least, it reads as charged still.
I'm saying bug, not that it couldn't be cold fusion Obviously there are a few things you could do to see what is happening but I think the fun experiment would be to run down to something like 20% and then try what you have been doing. If you go from 20% to 100% it shouldn't take very long to see how it runs down if it is a bug.
Maybe it will correct and show 15% very quickly, maybe you'll see the percentages drop like seconds on a clock as it reports accelerated discharge or maybe you'll get a low battery warning at 95%! I am curious to see what it does.
Most likely it will just be wrong and shut down when it doesn't have enough juice without really giving any indication what it is doing. But we can hope for something more exciting
JP
Okay, I just had it happen again, and it is happening during adb push,
Maybe my computer is sending the update and throws in 1000 mAh as a tip.
Does this happen to anyone else?
Now that I think I know when it is happening, I will try and replicate it when the nook is at 25% or so. Then I will collect my noble prize. (If b&n tries to claim it, you guys will have my back, right?

Interesting thread. I think it would be a noble prize rather than a Nobel as I suspect even B&N haven't found a way round the laws of physics.
I suspect the battery calibration is somehow getting mangled during the push somehow. What is quite interesting is that the battery monitor widget screenshot does show the charge at 100% whereas the battery voltage has only recovered a little bit. As the previous history indicates one should be getting close to 4200mV when the battery is really fully charged. Li PO batteries normally show a reasonably linear discharge curve from about 4200 at 100% down to about 3600mV when they are exhausted.
What, does the noble prize not have as much money, or something?!? Grumblegrumbleauto-correct-grumble...
I have wiped battery stats, rebooted a couple times, and have been using the nook...now at 93%.
It was at 78-80 before the miracle.
i personally would try using the Die Hard battery Calibration script and see what happens...
Yeah...you thought this thread was dead, but no.
Although I am unfortunately beginning to lean away from it being cold fusion. This time it happened upon connecting to ADB, no push or anything. That does kind of sounds Ike a bug.
But I did leave the whole history up for your perusal since the miracle energy. It's been a couple hours maybe. I was around 80 when it happened and I am just back to that level now.
You can see by the green portions, I noticed the miracle battery increase after I disconnected and it happened again upon reconnect a few moments later. Although to a much smaller degree as I was still running on a magical-miracle full charge.
I posted about this a while back.
With some microUSB cables, connecting the NC to a PC will munch the battery stats file and show instant 100%. You then have to leave it and let it charge fully and reset the battery stats using a battery calibration app or some other method. This happened to me using more than one micro USB cable, but I have several that do not do this. Given the pain it is to fix this problem, I just decided not to ever connect my NC to the PC again... wireless ADB and manage it over wifi instead.
Yes, there's some weird bug with this, it's been this way since day one. You'll see the level drop off drastically in steps.... It'll look normal, then boom, -10%, normal for a while, boom, -10%, etc...
Ah, so it just comes out in big chunks. I was wondering how it would eventually have to account for the discrepancy.
I had forgotten about this thread, sorry. But the heart remembered, so I have one last screenshot.
I never could actually catch the device catching back up, it seemed to just ease its way into it, if at all. But the other day I had the "instant charge" happen again. Later I flashed an update and left it in CWM for a couple hours. After flash, the system corrected itself. Have a look, the flat line is CWM.
I think I may have to return my noble prize.
Hello,
for months it has been happening that when the battery usually reaches 25% (but not always sometimes even 40ish) the battery indicator drops to 19% and it could either remain stuck at that value until the charge actually drops below 19% and continue the usual drop or it will rapidly drop to lower values in big steps like (19->10->4) in minutes to finally actually automatically power off. The strange thing is that it's all fake! When I power the phone again the % will go back to where it should be before this virtual drop happened and continue its usual drop, it always worked until today when for the first time it continued the "game" non-stop until the battery ended the actual charge (for hours)! You have to consider that i was in a place in the mountains where the gsm coverage was very low/non existent so it could be connected. But it got me worried because it couldn't control it!
Apart from a solution I'm asking also what the reason could be. It could seem like a battery problem but why would the phone actually recognize the actual charge after it powers off and I restart it ? Seems like a software problem (battery driver maybe?). But I wouldn't exclude that it could be the battery maybe when the charge gets low the voltage drops dramatically under stress to a point where the phone thinks its almost empty.
I'm using cm7.2 kang 119 with standard kernel.

So you say it's done that for a while... obviously it's not possible to pinpoint an app. I guess then you have some funky cruft buildup (say, a lot of rom flashes and some settings getting squiffy) or your battery's dying. I know for sure that the rather excellent Battery Widget Reborn can give a health check on the battery as part of the widget (although I dunno if it's GB compatible). The second solution may be to try a clean wipe. It's drastic, yes, but can clean up any lingering problems if you've been updating for a long time without the occasional wipe. If you haven't...then I dunno.

I'm not trying to be rude. It's just that battery stats are reset after every reboot, so wiping them does nothing. It's also easier to be blunt to get a message across.

Mine force closes 1 out of 7 charges at a random percentage...today it was at 53%...it shows cc% but in reality the battery is drained out...I am not sure what is the problem...this showed up after I inhaled wiui 2.5.25, other than that I have minor issues with this rom...I really like it...only if I could make the radio work...

What kernel? Bb? Ril? Obviously your problem started when flashing wiui, have an idea what to try.....?

Bb=725 ril=0218(10b) the kernel is the latest OC kernel from temasek (any suggestions there, is there a better one for wiui/miui roms?).
I'll do a battery wipe after a full charge and see what happens next...

Moving to Q&A
Dear fellow enthusiasts,
since a couple of days, I'm experiencing sudden device crashes when I'm using it for network related activities, mostly over the 3G network (for example, I'm typing out a message on the Facebook app, and the phone goes into boot loop or simply "shuts down"). I had only recently upgraded to the 4th beta build for the Cyanogenmod 9, hosted here on XDA , so I suspected it would be related to this. However, upon reinstalling both the previous version and the new mod from absolute scratch, the issues remained the same.
I had noticed that after each crash, the battery charge displayed as very low (2-6%), whereas I'm certain the charge should be much higher. So I thought it might be some sort of corrupt battery-cache issue or something.
However, and here's my actual question, I just now noticed that my I9001 battery is slightly bulged, on both ends. This bulge starts just above the white printed SAMSUNG lettering, and it ends just bellow the QR code. I can't for the life of me remember if or not this is normal, so could someone please confirm this for me?
And while we're at it, could a faulty battery affect my performance as such (making my phone crash etc)?
Thank you very much in advance for any help or information anyone could give me.
I confirm, battery is slightly bulged in those places but it looks like a production "thing" to me (I hope I understood what you mean), no need to worry, I guess. Looks like corrupted battery stats, try to wipe it via recovery (phone fully charged, plugged in - then wipe battery stats). After that, i recommend one or two full battery discharge - charge cycles. I've noticed hovever, that after each full factory reset I have for about 20% better battery drain, than after flashing many ROMs, kernels and updates (cache and dalvik cache wipe only), my battery drain is getting pretty annoying. Try a full factory reset, if wiping battery stats didn't work.

Thanks a lot for the confirmation Jacol !
Anyone else who can confirm a bulging of the 1650mAh battery for the I9001? I'd like a large enough sample group if possible.
also happened to me
solved this problem by buying another battery...

Thanks Blumdum, do you mean you also had your phone crash on you?
yes
i charged the battery
after some time my phone turned off
i restarted it and i had only 2% battery left
then i took a look on the battery stats and there was a huge drop from like 95% to 2%

Thanks Blumdum, I've ordered a new battery, it should arrive within a couple of days, I'll confirm if this fixes the issue.
Same thing happened to me,i will order momax 1700mah

Hey people,
I received my new battery last night, I went for an Akku Powercell of 1800mAh. Charged overnight, been using it all day, no problems whatsoever to be found.
Thanks again for the assistance!
Swollen battery = defective!
I'm sorry but I've encountered this as well in the past. Normally working phone with sudden shut downs and huge drops in battery charge. It took me a long time to convince me that the battery was defective. So maybe this would save you guys some time in finding this out!

Hey, try to use cm10 for a few days, if the problem gone then your battery is alright, and please stop using beta roms, regret are so buggy and slow: )
Sent from my GT-I9000 using xda premium
In general healthy batteries DO NOT swell. Buy a new one before it explodes or starts leaking...
Hey all, just because people keep on posting, the battery was indeed defective, the roms were absolutely fine and the new battery is performing marvellously!
Thanks again for all the input !

I have the exact same problem with my sgs i9000-gt.
My phone turn off itself ( no restarts, its a complete shutdown ).
First, I thought i might be a problem of GB 2.3.6 rom i was using, so i updated to latest cm10 but the problem persists.
If you restart the phone after the shutdown than i shuts down within a minute again.
Also the battery drain is pretty fast. I notice the same bulges on the battery as reported in this post.
I did the battery calibration thing as some people suggested, but that does not solves the problem. However, it got rid of the fast changes in battery status which was happening before. Like when you restart after shutdown at 80% battery status, it will show like 2% battery left and after few minutes of charging it would boost back to 80-90%.
But still the battery drain is pretty fast. It discharges from 98% (i cannot get to 100% charge, 98% is highest) to 50 % within an hour, just idling.
And when i am around 40% or so and if i recieve some message and try to open a app it shuts down again.
I have ordered a new battery just in case. Will update here if that improves things for me. But i will still like advice on which is a more economical kernel and rom for i9000-gt? Some people suggested slim bean + semaphore on some forums but i would like to have some more concrete advice before i change more things without knowing the source of the problem. I would be grateful if someone can suggest what is best to use with some details( version, etc). Thanks for that in advance.
I thank you all (users + developers) for all the useful information provided on this forum, i learnt a lot although i still am not able to fix my problem . And I hope someone might come up with a concrete solution for this problem. If there is a solution which I might have missed, I thank you in advance again and hope you will be kind enough to point me in the right direction.
cheers
update: the phone stays alright if u dont do anything on it, but the moment you being doing something on it other than playing with system settings, like run some app, especially something that uses network / wifi, it shuts down. none of this happens though while its plugged in. it happens only when its on battery.
problems fixed so far after replacing the battery

I flashed back to stock samsung rom ( from the value pack) and the problem persisted.
today my new battery arrived and all the forementioned problem seems to be gone with the new battery, my phone seems to be working fine for last 5 hrs without any restarts or crazy battery drain. will test the same with custom roms again. As of now it only seems that problem was the battery.
Cheers.
thanks to the forum and developers
Heys Guys Im having an issue with my Captivate, its was working fine for the past week. It started giving me problems like battery temps too high, cant charge, had to charge it manually, removing battery & charging it all night. All this happened when im with stock rom latest with leaked 2.3.5
& i did unlock this with changing the 01 digit to 00 in efs file.
From the past 2 days im trying to install CM10,9, 10.1..... after installation it shuts down itself. Not able to use it.
Is there any way around to make this work. If pics are needed i can provide that too.
Thanks
No reply... :/
Some one should have had an issue.

When/how does it happen?
What are the changes/mods you made?
Did you restore anything?
Did you try different kernel settings?
Did you try flashing a different kernel (like Semaphore?) or flashing a different ROM?
I could be asking more questions but really, I dunno what causes it, I can only guess. Also a search in the CM10.1 thread might give you an answer to your SoD <-- Should've been your first step*

It just happened, battery temp too high errors, thought flashing CM9 would solve this, was bored of Stock Gingerbread, flashed corn kernel & flashed cm9 rom. I did mod anything else. That all

Battery temp to high is a big problem. Did you overcloak? Have you running bunch of stuff at the same time?
When it shuts down, does it reboot by itself or you have to do it manually?
Sent from my SGH-I747 using xda app-developers app
Sounds like Battery health status does not equal healthy. That forces an immediate shutdown, whether due to temperature or excessive internal resistance. That's because once a Li ion battery reaches critical temperature, it combusts and destroys your phone, burns you and anything around it, etc.
GET ANOTHER BATTERY ASAP.
Stop trying to circumvent high temperature shut down.

Recently i bought a new battery, original samsung make, it states the same thing "charging paused for battery durability" sometimes "Charging stopped battery temps high". No overclocking here, just used to call, receive & wifi hotspot. Currently i charge battery in a battery charger & use it in phone.
U pointed out something right, sometimes screen just goes blank, i have to manually switch it on.

But im not able to under stand, why is Cynogenmod shuts down itself after installation, can i just stop shutting down ?

I think it's not CM related but hardware related. Does this happen when not using the wifi hotspot too?
I'm thinking your battery is bad (even if new), charger is bad, connection is bad (maybe from water/humidity) or that your usb port is bad. No easy way of finding it other than testing.

May be yes, the phone some times just goes blank, i have to manually switch ON. The same battery works well in my frnds phone quite well.
Port dont know, i can copy files no errors even now when i plug it in on stock gingerbread the battery doesnt charge but can copy files as before.
Since the batt works well in other phone, a couple of ideas. Perhaps silly to ask, but just checking:
did you wipe battery stats in cwm after flashing?
did you clean the phone's battery terminals with a bit of alcohol?
what's the battery health,temperature and voltage history look like, if you can get it. you can log it with battery monitor widget or similar app. set to short 1 minute interval for testing.
