I live in Colorado and snowboard all the time with my bionic while listening to music. I keep the phone on the interior of my jacket (basically the warmest place possible). When the bionic gets cold it starts to drop charge fast! Probably at a rate of 20%/hour on cdma only with wifi and gps off. My old iPhone 3g with a 2 year old battery was nowhere near this sensitive to the cold. Have tried a different OEM battery with the same results. Anyone else notice this?
