I noticed that my battery on my 700w drained about 50% faster when I was in locations that only supported 1x during the majority of the day (battery died before end of the day around 8pm), versus places that used EVDO (had about 30% left at end of the day) ....
I noticed this on two occasions, and in both circumstances used the 700w approximately the same. Was wondering if anyone could confirm this, or noticed the same thing.
