I have flash this Radio 2.07.50.27_02 on Saturday night and on Sunday (Yesterday ) i have verify immediatly that the drain was less. But today i know that is true. I use the phone in the same way i use every week day and on this time, 13:50 , i have 83% of Battery. I will confirm this again tomorrow.
I wan´t only give this information for anyone that wan´t try this Radio. I have try a lot of Radios but this is amazing.
Sorry for my bad English.
