[alex c]

ok so i installed android froyo 2.2 (darkstone build the newest one desire build) on my htc hd2 everything works phone, web,mms, keyboard just everything however the battery life is horrible i mean bad. with out using the phone and just on standby by the afternoon around 3 or 4 i have about 50% battery and yes i have tried app killer from the android market still no good. i know my battery isnt bad cause on my regular windows os it can last me a day plus so i was reading and other people dont have this problem with other os but its kinda confusing to find the rest and people dont really give enough feedback on other roms so what im asking is that does anybody eles have problems like me with the battery? if you dont can you please tell me which android ROM is best and send me a link so i can try it out thank you
