G1 - powerfull battery backup

The downside of all the talking, Web surfing and content downloading is that it can quickly run down a phone's battery. The G1 promises up to five hours of talk time and nearly 5 1/2 days of standby time, but who's going to simply chat on a smartphone or let it sit gathering dust?

I gave the device a fairly realistic battery rundown -- on-and-off use of multiple functions and applications and the phone's 3G and Wi-Fi network capabilities. It's safe to say people with a serious multimedia habit will have to keep a charging cable on hand.
