Hi,
I am trying to do the battery calibration piece but my phone never reaches 100% when the phone is off i charged it for almost 3-4 Hrs.
can some one help me?
New battery, like $10
i have two batteries now still i see the same issue, it started once i moved to GB Roms, before it was pretty good.
It is normal between 96% and 99%.
Is it normal to not reach 100% when i turn the phone off and charge it?

There has been talk about this occurrence before, but basically it's a battery-life saving feature of Gingerbread. Rather than hold your battery at 100%, which will decrease the battery's life, it charges to 100%, lets it dip down to a certain threshold (like 90%, for example), then recharges again.
That's my understanding, anyway.

Like jmtheiss said t's a GB surge protection not to overcharge the battery. It's a feature not a bug
does this mean we can do battery calibration on GB roms?

Two things regarding Battery Calibration :
1. For Better Battery Life : Always charge upto about 90% and use. Recharge when you reach 10% or even less. This will tremendously increase the life span of Li-Ion battery.
2. As regard to 100% charging :
(i) Boot to CWM, wipe battery stats.
(ii) Reboot and charge until 100%, Disconnect from charger
(ii) Power Off and connect charger again. Charge until 100%
(iii) Boot to CWM, wipe battery stats again.
(iv) Power on the phone and charge until 100%
Done.
Repeat the same, if you wish to re-calibrate the battery after some time.
Tip: Always re-calibrate battery and charge to 100% before flashing any ROM.

i am trying to follow these steps but my phone never reaches 100% @ the third step i have been charging it for 3 hrs..
Which ROM are you using? Because I know some ROMS have specific issue with battery charging. Please let me know

As I fiddled around with most of the ROMs out here in XDA, would suggest you to flash a KK4 build like Serenity or Illiminance, if you want a stable GB ROM. KK4 is the latest captivate GB leak and the ROM is awesome. Also, the ad-hoc wi-fi through modifided wpa_supplicant works in this build. The ROM is fast, stable and got good battery life. Try to flash the ROM and I'm sure you will get a great GB ROM without troubles.
Hit thanks, If I helped you out
Try charging with screen on. You'll hit100.

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)

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 .
all the other millions of posts on the subject no way found to increase the figure .

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).

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...
I never had this problem until recently i've flashed to Cog 4.
It started after i did a full charge. It discharges to 80% and to 50% and to 20% and to 5% and then died off within an hour. My phone heated up even though when it is not active.
Now, after changing a new battery. I find that i can't charge it above 85%. I re-flashed with Phoenix and Serendipity. The maximum charge still stays at 85%.
I've cleared the battery stats and nothing changed. I need help here.
You might find this thread useful
http://forum.xda-developers.com/showthread.php?t=806211
It has some discussion about cog and battery life, but I suspect it might be outdated. Either way, it should have good info for you on how to get the battery fully charged
First of all, with custom roms, battery drains much quicker than normal, but i think you need to do a calibration. Charge your phone for like 12 hours to make sure its completely full, then drain it all the way until it dies. Then make sure its completely dead and wont turn on (sometimes the phone thinks the battery is dead, but its not. To solve turn on and off until there is no more responce. Take out battery, then try and power on. This will get rid of any static charge in the phone. Put battery back in and charge for another 12-15 hours to make sure its completely full. Go into recovery and wipe battery stats. Then let it die. That should do it.

yes and no.
custom roms wont necessarily use more power, in most cases less. and technically most power consumption is controlled by the kernel, and secondly the installed services in the ROM. new kernels useually come with a new rom but you dont have to keep it or you can upgrade it ect. But yes, when changing the kernel either by itself or with a rom you should reset battery stats.
I suggest drain it dead, plug it in until it is full, reboot into recovery and wipe batt stats (or use SGS tool script) WHILE PLUGGED IN, unplug.
or if you have an external batt charger, wipe batt stats in CWM then put in full battery.

When I said custom roms i meant that when you are on something other from stock. And for the most part, unless you are on a minimalistic rom, you do get worse battery. It is a known fact. Sure I have gotten 50 hours out of a rom/kernel combination, but it was never consistent. I had to flash back to stock and masterclear because i have random shutoffs and need to return it, and im seeing easily 30 hours out of stock with 3 hours usage of web email phone. Maybe its not the same for you, but stock has had the best consistent battery life for me.

install the battery calibration app (by nema).
let the phone reach 100%, then reboot without unplugging. as soon as it reaches 100% again, immediately hit the calibration button and unplug. do not wait, thinking that you are going to trickle charge. for some reason, the battery will start discharging as soon as it hits 100% even when plugged in. i think it's a hardware issue.
this method has worked well for me. just wanted to share with the rest of you. cheers.

if u prefer to do the simpler way, (assuming u have root) . simply flash clockworkmod recovery and you'll have options for wiping battery stats. and the reason behind 95% after fully charging is because htc's stock battery is simply... cheap. u charge to 100%, and the battery thinks that 100% is too much, thus before reaching 100%, the charge is already cut. so the 100% is just eye candy.. the actual percentage at full charge might be 98 or 97, we dont know..
source : tested this with seidio extended 2500mah battery with seidio's charger and htc stock battery with htc stock charger.
results : seidio battery stays at 100% after full charge while htc stock battery instantly drops to 95% after one minute of full charge

i don't see how it's easier to boot into recovery and erase battery stats manually when the app does it automatically
hello
i just wanna ask something about my battery life on my x8...here's how it goes first i fully charge my battery up to 100% until it says on status battery full...then i unplugged it..after it i texted for a few minutes...and i check the status of my battery and it says: 28 mins 23s on battery..my battery is on 96%..is this normal.? or somethings draining my battery,?
i use minicm7 2.2
this is normal since battery is heating itself while charging, and when it cools down it shows less percentage of itself... to maximaze your current battery life, calibrate the battery:
1. charge it to 100% no more no less
2. leave the charger PLUGGED IN, and reboot to CWM
3. there you should find somewhere under options or advanced "wipe battery stats", and you press that
4. reboot your device and when it starts up it will show about 91%, charge it to 100% and you have your battery calibrated
NOTE: the charger is always plugged in
ok thanks i'll try it... one question should i drain the battery before calibrating it.?..as in zero percent??

Yes , that is recommended.
Also , one advice from me.
Even after calibration , whenever your phone says 100% charged , reboot it while the charger is plugged. You will get the exact battery charge after reboot.
Do it every time your recharge your phone.
Then stop rebooting when you get a 99% or 100% after a fresh reboot. Trust me , it helps.
ok thanks for the advice i'll try that too...
it is normal dude ....mine is giving 1day on heavy use
use zepplinrox's supercharge script...it really made a CONSIDERABLE change to m battery usage time
I have one question: "Why my battery is giving 6-8h. My battery 2 days ago giving 24 and more hour." Sorry for my English, but i am from Poland
what happened 2 days ago? did you install new ROM?
The OP might not have needed to install a new ROM, just an APP or maybe just a combination of APPs running. My phone sometimes canes the battery in a couple of hours from 50% to nothing for no apparent reason. On both stock and custom (actually better battery life on custom) it lasts about a day but sometimes about 6 hours! Not sure what is going on as this happened on both the stock 1.6, 2.1 and the custom 2.3.4!
