iLounge has taken the time to measure how long you can FaceTime video chat on your iPhone 4 before its battery dies.

Three hours and 10 minutes, give or take a little, from a completely charged iPhone 4. That’s via Wi-Fi, as compared with a promised 7 hours of voice-only talk time over 3G, and 10 hours of standard data time over Wi-Fi—the difference is attributable to iPhone 4’s camera, mics, speaker, video and audio encoding and decoding capabilities all being used at the same time.

iLounge tested this on two devices and saw an average battery consumption of 30% per hour.

I had an hour+ facetime convo last night, that sort of battery life is tolerable and expected. The camera, screen, accelerometer, wifi radio, and two data streams to encode and decode with surprisingly low latency.

I can't imagine how my arms and shoulders would feel after a 3+ hour FaceTime chat.

Am I correct in assuming FaceTime calls are considered data, therefore are free when making global "FaceTime" chats? Basically im wondering if there are roaming charges?
