I re calibrated my battery yesterday and did everything right. let it charge, ran battery calibration, let it die, then recharge (without taking phone off charger) to 100%...and over night my phone didnt even get to 60%...it was on the charger for more then 7 hrs...Did i do something wrong? or use a wrong app?... I came across this forum that tells me to do a little more then what i did before but i'm a little confused about it from step 6 on down. Check it out and let me know please. my phones being really dumb. thanks

Think i have made a pigs ear of my new i9000, well its new to me, only a week old
when i got it i could charge to 100% fairly fast and then when id unplug my charger it would hold at 100% for a fair bit, certainly if the screen was off it would be their for maybe 1hr with push email, but then when i updated to the new 2.2.1 froyo i read to wipe batterystats, so i did and now my phone charges to 98% (by the way when at 98% its showing around 4.28V ,it used to show that at 100%) without a problem but it had to be left on charge ALL night, yes over 10hrs to get to 100% from about 40% and as soon as i unplug the charger it drops to either 99% or this morning it dropped straight away in a blink of an eye to 98%
whats the best thing to do, i really dont want to wipe batterystats again since i have to drain the battery fully and i have done that about 3-4 time since having it, since i was trying new ROMs
is it possible that if i leave it then maybe by magic it could sort itself out, i mean this morning my battery pro app i have installed was showing 98% but an other battery reading in the phone showed 100%, i have no idea how thats possible!!
*update*
guess I answered my own question, just charged it to 100% and unplugged it at 4.238v and straight away immediately after i unplugged it it went to 97% 4.191v so its getting worse.
am I getting no help because no one can help or have i posted in the wrong section??
any help would be fantastic
thank you
same problem with me
If you search around for battery drain threads, you'll find that this 100->98,97 phenomenon was specifically coded in for 2.2.1, ie: intentional. It supposedly makes your battery last longer or something by preventing overcharging, or something along those lines..

Thanks for clearing that up, yeah that makes sense that it will help the battery, it was not a huge deal just i wanted to know if i had messed it up but from what you said all is good
although the strangest thing this morning just before i read your post i unplugged my phone and it stayed ay 100% for about 4 mins which for me is rather good since i only get about 4hrs on screen time, but thats enough for me, i get easily 30+hrs with push emails
used to get half that on my HD2
I know you need to be rooted to calibrate a battery, but I am wondering of there is another way. Or possibly the Sensation software is jacked.
I have ahd my phone on its charger for hours. It shows full, but a battery monitor app states its only 97%. After reading, this seems to be a common issue.
I have already charged full, and pulled battery, reset phone and still the same.
I am no battery expert. Any suggestions?

Using the SEARCH function can only help you, battery expert or not. There have been many threads covering this.
1. Charge your phone til it hits 100% then turn it off while plugged in.
2. Remove charger until LED is inactive
3. Replace charger & the light should be orange/amber, charge til green again.
Repeat 2 & 3 until there is no amber light showing
Rinse, repeat a few times. If it goes from green to green right away just leave it for a half hour or so OFF and charging. Hope that helps, if not search just like I did
Hey all,
I am currently running CM9 (bhundven's 7-29 herring build) on my Galaxy S 4G, and I am having some problems with random shutdown. This has only been happening for the past few days or so (EDIT: and I have been running CM9 for about three months with no issues). It seems that the phone works perfectly fine until the charge gets to about 60% starting from a full charge, and then the phone randomly shuts off. The phone will not start back up unless I have it plugged into the wall, and the results are a little unpredictable. The first time it happened, I turned it back on and it said the battery was at 1% and charging. Now, after clearing the battery stats, it reboots to 60% battery. It seems to work perfectly fine after that, and yesterday it went all the way down to about 12% before I started charging it again. It just happened again today, and when I turned it back on it said it was at about 60%.
My charging habits are pretty bad for Li-Ion batteries; I tend to let the charge drop all the way to about 10% or 5% before I plug it in and charge it all night, way past what is necessary to get to 100%.
The battery does look a tad swollen, but I might be exaggerating.
I just wanted to know if this is a bad battery with 100% certainty, or could it be a problem with the OS or internal parts, etc. I can easily buy another battery online, and I probably will.
EDIT: Also, I have had some overheating issues with this phone, and I can often smell electrical smoke in the charger port area behind the speaker, which is why I say it might be an internal parts issue.
Thanks everyone,

You need a new battery. I was having the same issue lime 3 months ago; phone was dying at half charge the when it rebooted, battery would be dead. Then when I plugged it in, it would charge in 20 minutes and the repeat the cycle. Put the battery on a table to see if its still flat. If it rocks or spins excessively, its usually an indicator of a bad cell.
Mine JUST started doing the exact same thing last week. Battery is definitely swollen. I replaced it just this evening and I'm in the process of doing a full charge from 0->100 to see how things go. I'm 99.999% sure the battery was dead. Replace yours.
Sorry for the thread necro, but I wanted to thank the OP for asking this question and to the helpful replies. We just had a heat wave here and maybe coincidentally to that, I've been having random shutdown problems. Having looked at this thread and my battery, I can tell that I definitely need to replace that. So thanks, all!
I've been having this problem for the past 4 days, my Nexus S won't charge beyond 38%. I was due for a battery replacement, I got that today, and even that wouldn't charge beyond 38%, after reaching 38%, it says charged. Please help
A friend of mine had the same issue with his galaxy Nexus.
I am not sure if he did what i him worked. He never said anything to me.
1. Use your phone until it dries out and shut down on its own.
2. Start it up to make sure that it immediately shut downs from the lag of juice.
3. Plug in the phone, when it is off and let it charge to 100% ( do not start the phone until then )
4. Repeat the same proccess once more.
This might help set the battery stats that you have for your old battery that are saved on your droid.
If you are rooted it might help to cleat the battery statistics as well.
I'll try it tonight and post back

Your battery is gone. Order a replacement from shopcules.com
Sent from my P5100 Samsung Galaxy Note 8
I did get a new battery, still gives the same problem. And for some reason I'm not able to keep the phone off, every time I do that it just switches back on.

Couldn't get the phone to charge in off state, kept switching back on, and reached the same percentage and stopped charging. Also used battery calibrator app to clean the battery stats. :/
Hello guys,
I tried nearly everything to calibrate my battery but for somehow it doesnt work.
I flashed serveral recoverys and roms so i decide to recalibrate it.
I followed the instructions on xda, first without root app.
I charge my phone up to 100% after booting it shows 97%. Ill charge up to 100% again and reboot. I did this serveral times but after rebooting i get always something like 96 - 98%.
So i decided to charge again up to 100% and discharge all the way.
After a while the phone shuts down. Now i plug in the charger. It shows 52% (wtf)
Ill boot the phone. It shows 50% but after a while it shuts down immediately.
So i thought using an app for batter calibration does the job cause normally it does.
But it didnt work. So now in asking if some u guys have any advice how to continue.
If i dont use my phone, just lockscreen the battery lives for ever but as soon as im starting doing something its draining way to fast. Somethings not right.
Thank u very much and sorry for the bad english
