Recalibrate your Samsung Galaxy S the PROPER way

---

HI guys i will be showing you how i recalibrated my battery and it worked for me,

1.charge phone till full (EVEN IF IT DROPS TO 98 AS SOON AS YOU UNPLUG ITS OK)
2.drain the phone and i mean DRAIN turn on everything (sync,wifi,bluetooth,everything
3.once your phone automatically switches off try boot if not boot into download mode
4.stay in download mode until it switches off again
5.once it switches off try accessing it again keep on doing it untill you cant
6.charge phone till full (make sure you dont switch on phone)
7.once it says full take off phone charger and quickly put it back in make sure you do it fast and do this 5-6 times
8.without taking charger off boot into recovery
9.wipe battery status but as soon as you are about to wipe quickly take off charger once it wiped put it back in and reboot phone
10. give it 3-4 days and make sure you do battery cycles
11.try flashing a different modem im using ZSJPG link:http://insanity.rollus.net/addons/mo...SJPG-Modem.zip thanks to nitr8 and alll the other rom developers

thx m8 very well explained, ill try to do it later

Have you checked the battery's voltage while doing this? Or is there a built in deep discharge protection even in download mode?

your phone will have a bit of power left to go to download mode for safety incase you do brick it but you cant brick your phone when your recalibrating

Personally i would only go that extreme route if you have a battery problem .
Multiple full drains and multiple bump charges is no good for battery life .

I agree. I wouldn't go that extreme. if u r experiencing battery problem, use battery recalibrate app for galaxy s. (search xda forum and you will find it less than a minute)

It is more than sufficient to solve common problems

It's not so much a question of bricking the phone, it's more if you let a li-po battery (like the one in the SGS) go below a certain voltage it can damage the cells and drastically reduce the life of the battery

Ive read that such discharging your device (whether phone or pda) is not good for the battey, and that you should never try to force discharge it ...

Both bump charging and complete discharging can damage the battery.
Teaching this is both incorrect, irresponsible and dangerous as excessive discharges can under certain circumstances cause the battery to effectively explode the next time it is charged.

All this voodoo and mystery around calibration is silly. It's a simple process that need not be made any more complicated. Bump charging may be alright, however it significantly reduces the service life of the battery and so should not be done regularly, without proper warning.

I thought I would add my 2 cents to the battery thread. I am in the UK and have an XEU phone. I have gone through all different firmwares, modems etc. and all of them had one thing in common.....

Anything above XXJPY would just rape my battery and I mean about 50% in about 12h running barebones. Beleve me when I say that I tried all sorts. Currently I am running my own custome deodexed and stripped JPY, and havn't looked back.
