PLEASE READ CAREFULLY BEFORE YOU POST!!!!

Hello!!
i wish to know if someone could charge his defy+ to 100% with some of those fixes in froyo rom.

The thing is that some fixes charges to 100% BUT is not the defy+ 100%, those fixes make the phone use the battery like a normal defy one. But doesnt charge it to the real value in mV

defy full mv charge : ~4160mV
defy+ full mv charge : ~4320mV

So is there someone who using some fix could charge his defy+ to the REAL defy+ value? it doesnt matter if it says 100%, the thing is to check the mV.

The truth, to relate to your title, is in fact, that there is no fix that works for everyone...

I've read a lot on the original German topic for white rabbit, and the author Einsteinno tried to implement such a fix with a little help from his fellow beta-testers.

The conclusion was, that for almost everyone who tried any of the fixes another one or none worked... Maybe it's the build of their Defys, maybe bootloader or kernel or something else.

It seems you have tried a few and if none off them worked so far, you might have to wait a little longer...

I have got a fix I tried that some one tried on MIUI and they say it worked and as far as I know thats froyo based?? Any way give it a go but back up your original battd.bin (copy it to a SD card location) incase it fails so you can restore it.

Here is the link the fix and instructions is last post on page one. Please post on that thread if it works for you and what version your running.

I would guess that both batteries are fully charged at the same voltage ~4.2V - However you need to be carefull when you measure the voltage. Use a Multimeter and try to draw some current and measure while you do it I bet the voltages will differ.
The thing that differs on the batteries are the capacity (mAh), which in no way translates to fully charged Voltage. (lower than 4.2 does however say something about how much charge is remaining, but the discharge curve is pretty flat)
A battery charge circuit typically detects the fully charged capacity by measuring that the voltage no longer increases (and then continue to trickle charge for a while to get it fully charged).

EDIT: spelling

On cm7 everyone gets full charge. Its the MIUI (Pikachu n WIUI) that has the problem

What's the difference between the battery indicator while the phone is turned off and the one when it's turned on?

I own a Defy (Red lens) and have CM9 (Defy+) with its batteryfix. However, strange things happen with battery measurement:

-Turned off it shows 100%, and when I turn it on, it shows 89% or so.
-I plugged it when it was on 8% (turned off), and as soon as the battery indicator showed, it said "45%".

Now I'm charging it (turned on) and it shows 96% and 4146mV in BatteryCalibration (I understand this is ok).

I'm curious about it, and also a bit afraid of damaging my battery.
