I'm a new member and this is my 1st post.
I used to have similar frustrations for two weeks when I 1st bought the Storm.
"Blackberry Storm for Dummies" says the battery life is about 2 days only due to the large screen and color. The earlier versions could last a week.
I had help from a technical support person who asked me to cahnge myManage COnnections - Mobile Network Options to 3G instead of 2G / 3G as the Storm did not have to keep scanning for networks and the data line was always up after that.
I also did the following to have battery availabilty all the time:
A. Remove "vibrate in holster" for all my alerts - new email, sms etc. Vibrate takes up quite a bit of of battery life according to the manual.
B. Purcahsed an extra battery
C. Purcahsed a separate charger for the battery - not expensive.
D. Purchased an in-car charger to use on trips.
Seems a lot of expense and trouble but helps to ensure your blackberry is always up!
