Hi Guys!!
i've done what this link told
http://forum.xda-developers.com/showpost.php?p=10092321&postcount=11053
but everytime i reach 100% and unplug the charger, my battery percentage immediately shows 97%, be it charging with the phone off or on....
i already did wipe my battery stats in recovery a few times, the first time only it showed that the stats were wiped, after that every time i wipe the stats, it immediately goes back to the previous menu, without stating whether the wipe was carried out or not....
can someone help this noob out here.... thnx
FYI, i just installed darky's rom v8.0 with Voodoo's kernel 5.2(lagfix disabled)
when i was on stock, my 100% could last me about nearly half an hour
I have this problem too. (I am on Darky 9.02 and have seen it in Darky 8.0 too). BUT if your battery life is satisfactory then don't worry about it.
hows the performance on v9.02 bro?

9.02 is good but then so was 8.00. I personally think 8.00 was faster but its only been a few days and am still experimenting. I may remove the lag fix and still need to see if my battery is draining faster.
Also look at this post: Has some interesting but unverified info about the drop from 100% to 97/98% after unplugging

Do you really want it on 100%? Easy, once it says charged, leave it on the charger for another hour and when you unplugged it should stay 100 for a while

Problem posted hundreds of times along with solutions like search the Rom makers forum and read the posts re this problem for starters .
Simple solution save time and effort is to ignore it .

thanx all for the advices.... tried the QueenAmy method, result is:
heavily used phone: battery 'died' at 2%(???)
charged phone until 100%(phone off)
switched phone on while still charging: 97% (didnt have to unplug charger)
waited...then it went from 97% straight to 100%.(funny)
then went into recovery to wipe bat stats.
rebooted and unplugged charger, battery still at 97%....
now trying to charge a bit more longer to see if can change anything... (fingers crossed)

not working bro...
left it on for about an hour, unplugged, straightaway the percentage drops to 98...
It's just a change in 2.2.1.
In 2.1/2.2, they 'stretched' out the battery life a bit to mark it up to 100%, in 2.2.1 they decided to just show it at the actual value. The reason your battery won't charge to 100% is to prolong the battery life, because if the charger always charged to 100% it would have a high chance of overcharging and damaging your battery over time.
There's no real change in battery life.
I reverted back to 2.2 and still have the problem. Maybe i shouldve flashed on 100% battery... Is it possible to solve if i do another fresh flash with 100% battery?

Just to clarify this, you actually cant over charge the battery on the SGS nor Li-Ion for that matter, what happens here is that the battery goes on trickle charge pre 2.2.1 and battery degrades faster if its kept at 100%, 40% is optimal for storage now with the recent changes the phone will pretend it has charged upto 100% but will stop anywhere from 99~97% yes there is no loss in battery life but dont consider 97% as the new 100%, theres already a 3% loss in this to begin with.

Is not a problem its the current design .

thnx mate.... i guess i'll just have to chill about this....n stop wasting my time right... ;-)
Is it true that the porcentage of battery u have when u flash ur phone is the one that will be used as the new 100% ? also whats the procedure i should use to erase the battery stats? my phone dies in like 4 hours , let it discharge, charge completely and then?
I don't think so, cause i always flash my MS anytime i wish even when the indicator show <20%, or when charging on UBS
I also never bothered to charge fully before flashing. Though I think resetting battery stats does help indeed.
i also read something similar to this, someone told me to charge to full, then let the phone discharge UNTIL IT TURNS OFF BY ITSELF (=battery completely dead), then charge to full again and then delete the file batterystats.bin in /data/system folder (root required).
i suppose this is what you are talking about?
i will try this in a few hours (currently discharging the last % of my battery).

Im confused im supposed era the stats before right after chanrging full charging the phone or i sould let it discharge m, then erase the stast and then full charge the phone?
What's your ROM?
On froyomod do you have option to calibrate battery and wipe battery status
Well, I've flashed it to FroyoRom with approx. 40% charge, played around a little, the next day when I was normally using it and my battery went down to 30% I deleted the battery stats, the system rebooted and voilla, I was at 50%
I don't know about this full charge - discharge - full charge - delete stats version. I guess I'll try it on an occasion and see what happens. At this moment I'm at 90% after being disconnected from charger for 5 hrs, though I wasn't using the phone much during this time.
...and currently finishing the same charge - after 1 day and 17 hrs currently at 20%. My Milestone never made it through the day without having to charge it through the night. Love it
The FroyoMod is really the best at the moment...
Havent you noticed that when you charge the phone powered off it takes like 40 % more time for the batetry to charge but it also makes the battery last longer? is there any truth in this or im just crazy?

This is a very well know issue related to battery calibration. Take a look at the many calibration threads to learn about bump charging.
Basically, it takes longer with the phone off (or when you pull and put back the battery while charging) because in some cases android was stopping the charge before a full charge.
Try this
Charge your phone to 100% (inside android)
Turn you phone off
Reboot
Pull the battery before it boots
Wait for the ?
Put the battery back in and notice the %
If it says 60%, then you had 40% of your battery not being charge.
If you leave it in that spot and wait for it to go to 100%, your battery will be better calibrated.

and this hasnt been fixed even with gingerbread? yeah i have gotten the message saying it has 60 % :/
I pay no attention to the battery meter anymore. I've found that it just reads low. It's not that it doesn't get a fully charge, the phone can't read the level correctly. I tried draining the battery once by playing an episode of Top Gear with the screen on full brightness. The phone said the battery was at 5% but the video kept playing for another 1.5 hours.

noup , when my batetry says low , it dies pretty quickly
Go with mV.
4200mV=100%
3200mV=0%

Hello guys.
I know you're all tired of people QQing about battery life, but I've yet to find a thread that addresses my issue.
Anyways, I'm running cog 4.2.2, and recently I've seen a drastic decrease in battery life with no change in the way i use my phone, no new apps, and no new roms. I've calibrated my battery about 5 times now, and the same for rebuilding my batterystats.bin. I used to be able to make it through a full day without charging with battery to spare, now it dies sometime in the evening even after bumping the battery charge several times. I charge it every chance I get (between classes, when I'm adding files to it via usb, etc) and it STILL dies. at one point, I observed that my battery dropped 15% in 30 minutes. I used os monitor to check if any apps were running using a lot of cpu, but nothing uses more than about 1% (most things usually show 0%) except the operating system itself, which is at about 7%. Should I just cave and buy a new battery from amazon, or is there something else I can try, short of flashing a different rom?

Yes 10 char
maybe your batterystats are ****ed up? i deleted the file once before with sgs tools and then wiped dalvik cache and it for some reason seemed to fix my battery issues, and sped up my system somewhat
Don't bump charge so much. Lithium ion batteries aren't designed to go to 100 so often and over charging can result in decrease longevity of the battery itself. The phone has a feature to prevent over charging. When it's on the charger the second it reaches 100 it will stop charging and let the battery trickle down to 95 or so and starts that cycle over again. Too much bump charging can actually damage the battery.
After deleting the batterystats.bin do you let it go through a few full drain and charge cycles before making a judgement on the battery life?

I realize that, and I can't make it through the day without charging it. I only charge it when it's at less than 10% though.
Also, I have deleted the batterystats.bin and let it go through a full drain and several charge cycles. It didn't help at all.
Also it's worth noting that today I left it on the charger powered off after it reached 100% while powered on. I left it plugged in for three hours, and it never indicated 100% while powered down. It stayed at about 90% full, more or less.
replacement oem batteries are relatively cheap, cause it sounds like you got a lemon. Sorry man.

For 8 bucks, it's worth a shot. The most perplexing thing is that it won't max out while the phone is shut off. Tell-tale sign of effed up battery?

Yeah that would raise a big red flag for me.
Try a different rom see if that offers any better battery life, I doubt it but It's completely free to try. Something to mess with while you wait for a replacement. And if it turns out to work then you will have 2 batteries.

going to try wiping the dalvik cache before I order the battery. Wiped batterystats.bin while I was at it. Maybe it'll help.
I got about 11-12 hours today, but I did nothing but text really. This is after full charge, deleting dal cache, and deleting batterystats.bin and then restarting. I mean I recieved a few pics but I really didn't do anything on my phone today other than that. That's just pathetic, since before I was getting through a full day (8:30-2am roughly) with battery to spare and I was using it a lot more heavily than I did today.
Hello . This is my first post here. I am having a problem with my battery. i recently bought a new one with 1700mAh,is a compatible one. now the thing is i left my phone to fully charge but is charging only to 89% and stops. my guess is that the phone only see the 1500mAh and the rest of 200 cannot. is there any way to make the phone charge to 100%? Thanks in advance!

i too have a 1700mah battery from the Ace 2 and it works like a normal 1500mah battery would. the first time when i put it in i shut down my phone completely and left it charging for 16 hours (although it did have 50% out of the box). Another thing i learned is that it's better to charge Li-ion batteries when they are below 20%, because they have a limited charge cycle (about 300 charges i think) so when you charge it from 70% to 100% it counts as 1 charge. i used to charge my original battery like that and only lasted 7 months (then my phone restarted randomly, couldn't turn on when actually having more than 70% battery left (the indicator said the battery's dead, but when i pluged it into a charger and turned the phone on it had more than 70% left) !!
so is there any way to make the phone see the 1700mAh?

Does your new battery 3 or 4 contacts? The original batteries have 4 contacts. I think that by the fourth contact phone receives information about the charge, and if the new battery does not have that contact phone does not receive charge Information so it approximates.
what's your 1700mah battery brand and model ?

the battery have 3 contacts same as the original. also the brand of the battery is Andida for samsung I8160 but is also compatible with my s3 mini.
ok i've got the same battery and the only advise i can give you is to charge the phone 16 hours non-stop and see what happens (better be turned off). that's what i did when i charged my battery for the 1st time.

Try to calibrate it manually. Charge the battery to 100% then with a root explorer go to data/system & delete batterystats.bin file & then unplug the charger.

I think that clearing the batterystats.bin file won't do anything, cause it just stores the info which is shown in the battery usage window in settings. And every time you charge your phone it generates a new batterystats.bin file. Not sure though

I did that and still from 100 to 90 in a few mins. I read somewhere that this is because all of the background apps but it still lasts a day with normal use (a little games, little browsing, a lot of listening to music and a few calls ) so it's no problem for me.
