OK, now it is 19.00 CET . I have 81%....Very good.
The procedure:
First at all I drained my battery do max, but not forced to shut down.
Plug my charger and let it charge for all night. Leave it on charge even it shows that is full.
Disconected charger, and power off my phone.
Plug in charger and let it charge, waiting for a green light.
When green turns on, disconected my phone.
Power+VolDown = HBOOT
Delete batery status.
Reboot.
This is the same procedure everywhere described. But without one step of charging (also described above).
My screen brightness is set to auto, using 3G preffered option.
Also my wi-fi and data are turned off during calls.
Animations are off (I don;t like them)
I have to mention that brighter screen means more power consumption even on original Android. More darker, more power left in battery
This is all I have to say. This is not something special. Just followed instructions how to recalibrate my battery.
Regards.
