on my curve...i'll be lucky to get a day and half from a full charge with bt on. email and phone use only. that said, it spends a good portion of the day in the charging cradle at work so its usually at full charge. i suspect i'll have the same charging routine with the storm in it's cradle.
i'm slightly confused with the charging adapters for the storm though. rumor is that it uses a different type of connector than the one used in previous bbs and on my curve. if that is the case then hopefully i can find an adapter. i'd hate to purchase new travel and car chargers just for the storm.
