Problem with battery after install 2.2.1 jpy

Since i flashed my galaxy s with 2.2.1 rom jpy (XEU product code) from kies i have a problem with my battery: when the battery is full charged at 100% and i disconnect the phone from ac adapter the battery go immediately at 98% or 99%, is there a way to fix this problem? I've just tried to discharge, recharge and wipe battery status with sgs tools but nothing happened...

There are already multiple threads about this. Please search first next time.

Thank u! I've read almost all posts, but my problem isn't a drain battery problem, my battery discharge normally. The problem is : when i unplug the charger when the phone is fully charged, the battery passes from 100 to 98 or 99% instantly!

It's only 2 percent!!
I don't know why people are so sensitive about this issue.
It's a minor bug which hopefully will disappear in next firmware.
Until then just relax and enjoy latest firmware.
At least you don't have battery drain problem

Ya from my reading it seems to be agreed that it us a bug in jpy firmware.

it is not a bug at least with me.. the phone remembers off all batteries the hightest mv it obtained and unless you reset battery settings that becomes 100%. when plugged in and charging the battery most likely obtains that but then if it can hold a full charge any longer (ie wear) will drop to its max charge instantly once unplugged. I have 4 diff batteries .. one goes to 96 when unplugged , one to 98 ,, etc. etc. but my best one does stay at 100 when unplugged.. hope this helps.

Another bug is the battery usage indicator. The battery icon does not always reflect the amount of charge that is available. For example it may be 50% used but icon shows 75% available.

My understanding is that discharge curve is not linear and at 50% usable voltage you still have more than 50% life ahead...

Battery Drain Fix
think it was deleting the battery stats but not sure .

I've read this post but it isn't my problem. My broblem is the battery go straight to 97 98 or 99% after i unplug the charger and the battery don't stay at 100% ever for 1 second. Are there any solutions?

this is normal for 2.2.. it is now detecting the mv in the battery and if it drops immediately this is due to battery wear.. i have 4 batterys they all drop different amounts but one does stay at 100% when unplugged. At some point your battery did stay higher thus the max setting.. i believe if you clear battery history in the recovery screen you will reset this behavior.
but i wouldnt worry about it.

But not always it drops to 98, sometimes to 97 or 99, but if i continue to plug the charger many other time and all the times i wait it tells me 100% from 97 the charge stay to 98, then 99 and sometimes maybe 100%.
However i haven't "battery clean history" option in recovery mode, i can wipe the battery status by shell command or by script in the sgs tools, is the same things?I've just try these methods by don't seem to work...
How can i do otherwise?
I hate this bug it makes me really angry!

Same thing for me!!!

I have the same problem. Still I managed to solve it after deleting few times the battery stats and after few charging cycles. Funny thing is that I have to reinstall my firmware and now the problem is back.
So, try to delete battery stats when the phone shows 100% and when is allmost discharged (under 5%) and give him some charging cycles.

1 day endure my wifi driver but JPA is up by 2.
In doc v7.1 is the jpa driver.

Can't seem to get my batt to get fully charge.

Just as what the subject is. I download batt app % but I can't seem to get my battery to fully charge. Icon says its fully charge but batt app says otherwise it's at 80%. Thx again.

I observe the same.

When it says fully charged, you should turn off the phone and continue charging and see if it goes to a true 100%

I had the same problem then reset the battery stats 2 mornings in a row after the phone was fully charged overnight.

I Was going to suggest teh same - get a full charge on it and wipe the batt stats a few times... This is accomplished in teh advanced section of CWM.

battery not charging to 100%

new to the atrix.
I installed the latest oat update, and the phone was @ 70% after charging all night. I also noticed it discharge updates only by 10% increments.
I installed the homepage Rom, and it charged overnight to 93%.
I've applied the battery fix, but that only seems to stabilize the display (I noticed it fluctuating before the fix)
is there a fix? I've done calibrations on phones, but I needed to get 100% and the charge while off. Not sure how I can calibrate if I can't get a full charge while on.

Use recovery to wipe battery stats. If it still fails to display 100% when charged shut the phone off. Take the battery out, then plug the phone in. Wait until the "?" on the battery shows up. Then put the battery in while it is still plugged in. Leave it like that for about 30 mins. When you click the volume button the battery will show only 5-10%, but turn the phone on and it should read 100%.

I'll try that. I already wiped battery a couple times in cwn

OK, then the 2nd part should do the trick. It works for me anyways. Once you do see 100%, wipe batt stats again and let the battery die, then charge while the phone is off. Should fix you up.

You might have to wipe battery stats several times. I had an out of the ordinary calibration problem between flashing roms and had to wipe everything several times before it started working properly. Also note, that charging up to 95%-99%, and unplugging and plugging back in and slowly charging past 95% is common and not a problem. The software is estimating battery charge. And if you do charge past 95% and unplug its ok if it quickly goes back down to 95% and then tapers slowly.
I voided my warranty and your mum.

You have to wait for battery to go beyond 95%.
It takes time but it goes their.
My personal experience.

Just drain the battery til it dies. Then plug it in over night while you sleep. Once you wake up wipe battery stats and everything should be good.

I think he has tried both of these methods. I know I did. What I told him to do was the only thing that worked for me.

OK J, it looks like that fixed it.
Although battery showed 4169, and I saw others with 4200
Thanks issued!

try discharging until the phone shuts off and charging it again without turning it off.

Hmm...battery should show 4203 when fully charged. Mine has actually displayed 4205 a couple of times.

I'm going to try it again. I tried a different rom, and it only went to 92%. I redid the battery pull and Saw 4185.

Right way of calibrating your battery!

I know it says that you have to full charge and discharge the battery after calibrating it via Battery Calibration but here's my way and I have browsed now for 10 minutes and a little phone call for 5 minutes and still had 100% left after I just looked up my emails now it's 99% :
(1 Calibrate the battery using "Battery Calibration" on the market.
(2 Let the battery discharge to 50% and power the phone off
(3 Take out the battery for like 5-10 minutes, now, put the chargercord in BEFORE you insert the battery, your phone will boot up until "Sony Ericsson" Logo.
(4 After the phone powers down insert the battery and charge till 100%.
(5 Now you have to discharge the battery a few times to ~5% and recharge it to 100% approx. 2-3 times.
(6 ENJOY your FULL calibrated battery with FULL cell potential
NOTICE: This needs time so do NOT use this method if you don't have time on your hands!
Press thanks if this helps/helped!!

Is there any scientific evidence that this way is better? How did you come up with this method?

i asked an sony employee on their private chat about that, they told me lettin it run down to 50% is the best way and then just like normal

3. and 4. seems like phone hardware don't let you charge your battery normally and you must trick with battery out,in method....

[Q] Battery drain while charging in airplane mode

I've got installed aurora 5 update 16. When I put my phone on airplane mode, when on cable for charging, my battery drains.
The screenshot is from two tries charging my phone while on airplane mode. As you can see charging stops after a while and the battery falls.
Any ideas why battery drains while phone is on cable for charging?

I have the same problem

I have experienced the similar problem before.The charging reading is fluctuating while I am charging and discharging. However, it will be solved if you have re-calibrated your battery of your phone.Here is my recommendation procedures on how to re-calibrating your battery of your phone:
1.Install "Battery Calibration" from Google Play
Link: https://play.google.com/store/apps/details?id=com.nema.batterycalibration
2. Switch off your phone and let the charger to charge your battery until it is full, and leave it charging for 15-30 minutes after the battery has been fully charged
3. Reboot into clockwork and wipe your battery stats (advance -> Wipe Battery Stats)
4. Reboot your phone normally and let the battery to be fully charged, leave your phone to be charging for 15 minutes after the battery is full
5. Recalibrate your battery using "Battery Calibration"
6. Let the phone to be discharged (or use it normally)
7. If the battery reading is still unstable, then return to step 2 and go through the procedures again for several times.
In my experience, it is a bit hard to recalibrate the battery if you have done it for once, but the battery reading should be perfectly fine eventually if you have run through the procedures for several times.
I hope this can help you to solve your problem!

Thanks. I'll try it.

You can try my ROM Mlora... For better battery life!

Same here on update 16 and 17. Tried multiple calibration tools, including CWM 6. No solution for me.
Strange:
After a night charging in airplane mode it looks like it's drained to e. g. 23% but when disconnected an reconnected again it jumps to 80 and 90 % in just a few minutes.

same here.. tried a few times and they all drained in airplane mode while charging overnight, with around 20-30% left in the morning..

I had the same problem and I realized that it was happening if i left wifi on

After several tries calibrating my battery, the problem still remains. Maybe it's an Aurora ICS 5u17 bug
