I own a samsung galaxy s2 which ive had for about 2 weeks ! Love the phone to bits but i am having real battery issues ! ive got the brighness down and the phone on standby with no background data running or anything and the charge will last only about 5 hours ! I dont understand how this is happeneing ! I changed to this from an htc desire and that gave me a full day at least and this is so frustraing as i am in love with this phone ! It runs the standard 2.3.3 and im considering selling it if the battery doesnt improve ! I bought an increased 1900mAh battery compared to samsungs 1600 and this gives me just over 6.5 hours life !! Please Help !!
