Very Low Battery back up in BlackBerry Bold Touch 9930

Hi There!!!

I am really impressed with the blackberry 9930, it has a good collection of features, but my only issue with thi handset is that it has a very bad Battery Backup. Such a huge brand name with battery life as bad as a low graded Chinese mobile. Tried my hands with customer care but as usual hopeless results. I feel that Blackberry should offer new and high graded batteries.

Is there any suggestion for me as to how to improve my battery life???
