chalk me up to sucky battery life on the iphone 3gs. brand new phone only about a week old and in the last 10-15 minutes alone my battery went fron 75% now down 70% and all i have been doing is text messaging on it occasionally. i have wifi, bluetooth, location services, auto brightness, notifications, data roaming, vpn all off. the only thing running is my push email to my exchange server and 3g, i have not received or placed any phone calls nor has any new email come in during this time.
i have purchased these products both to help ease the lack of battery life on the iphone. both of which stated they were compatible with the iphone:
2-in-1 wall charger

portable charger

is there any issue using these products with the iphone? i tried a charger from the ATT store designed specifically for the iphone and plugged it in and it told me this accessory is not supported and would not charge the phone.
