I got my HTC Desire from work and am really struggling with battery performance due to bluetooth, GPS, email and pdf conversions for emailing being used daily while on construction sites. Also my available RAM is always decreasing until i restart it. I've heard rooting and installing certain programes can help these problems as after 12months into an 18month contract it has begun to let me down from time to time. I would appreciate any help or info in simplest form possible
PS a second battery wouldn't cut it not too many power points in construction sites!
