[furiousgtz]

Ok. i hate create a new thread for this topic.
but i reasearch and found some info.
the battery on 6700 sucks, after the green light i take the charger out and i let it stand by for 2 or 3 hour it goes 90% 80%??? or after i surff the way on the phoneit goes 70-60% or low or 20min one phone it goes down to 40-50%
so buttom line is that the battery sucks whats the problem is there any way to improve battery life.

i have a extra battery charged in my car. just for backup.
