This is also one of the major reasons that WM phones get such terrible battery life in comparison.
My friend has the 8900 on T-Mobile, with WIFI and GPS enabled 100% of the time, (apparently BB is smart, and only enables these when needed--not all the time) but from his perspective, they are 'active.'
His battery lasts 2 days at very least. I nearly had a heart-attack when I heard that. My Vogue lasts 6 hours max with my current usage, which was much, much less than his.
I can't wait for a new phone, until WM7 comes out, I'm steering clear of WM. WM6.5 hasn't fixed really anything that I would consider monumental.
Palm Pre!!
(for now)
