Hello everyone, i recently upgraded to 3.0 from 2.1 and unlocked/jailbreaked. From cydia i installed the sbsettings battery percentage hack and the caller id to text message hack. Ever since then, my battery has been decreasing by 1% EVERY 2 minutes and so a fully charged iphone 3g reaches to 20% battery within an hour and a half. Even if the phone is not in use and i left it on 100%, when i check it again it will be on something like 70% or something like that. Does the 3.0 firmware use WAY more power than my 2.1 firmware did?? or is the sbsettings hack causing this?? or is it time for me to send my iphone to apple for battery replacement?? ANY IDEAS???
