MS800 low battery

[madbotte]

Hi all, i've a little problem with my ms800:
two days ago i flashed my ms800 with the official ITA rom to solve some problems with mms and internet connection.. well, from the moment i flashed, my phone turn off every time it reach the 40% of battery charge..
It was quite difficult to flash my phone (i tried 3 roms downloaded from this site, the official site and one from a friend, and for two times the flashing was failed) so i prefer not to flash another time.
I've read some time ago about changing the registry settings of battery level but really i dont remember which are registry entries and values and i've losen much time searching in internet today, can you halp me?
Thank you for any suggestion.

You should replace the battery. Or send your phone to a service center for diagnostics.

I'm not sure i've explain well my problem: when it's full charged the phone works well, but after a day, when it reach the 40% battery charge, it turn off with the exiting animation and it seems to me it's the OS that decide to turn off the device at that charge..
