@Vaxick -- Just tried the tightening the screws thing... holy S*#T i cant believe the difference it made! So much better now... very nice tip! kudos!

@CraigH -- I do an extreme amount of "push" data and basic phone usage per day as well, and I run my battery down very quickly. I really didn't want the size adage of the extended battery either, so i just bought another regular battery to swoop back and forth... but i must tell you, of all the things i have gotten to help me with my battery life/usage issue... THIS has be the best!
I know it's not a phone specific issue... i just use the hell out of my device and usage = battery drain. defenetely check this thing out... it's like an extra boost of life until you can get to power... i just love it!
