I bought this phone for my son and the battery life is really poor. On standby with very little use he is getting about 6 hours!!! This is horrendous, and he has to keep the phone off until he needs to use it. Any tips on improving the battery life? We bought the phone new from Argos in September last year, and the battery which used to last at least 12 hours has got worse. Its never really been that good, 12 hours would have been with hardly any use. WiFi is off, and data off most of the time, but on 2G when used. Any help appreciated, we are still using the original T-mobile rom.
