The bigger the screen, the poor the battery life is. I used to buy additional batteries and chargers for each phone I owned. Then I realized it's a hassle to charge the second batteries and, replacing the battery will have to shut down the phone. Now I carry around these external battery pack.
I have this New Trent external battery/charger. It's 7000mah high capacity. I traveled a lot that sometimes I won't get close to any computer or AC USB outlet in a few days. Sometimes when I travel international, I won't be able to recharge for over 30 hours. This thing works great especially I use the phone as MP3 player, GPS navigation, and WIFI hotspot (not now with this new GS2 ).
Amazon.com: New Trent Arcadia Pack IMP70D 7000mAh USB External Battery Pack and Charger for iPad2, iPad, iPhone 4S 4, 3Gs 3G (AT&T and Verizon), iPod Touch (1G 2G 3G 4G 5G), Motorola Droid Phones, HTC Android Phones, Blackberry, Samsung Galaxy S, Sam
Highly recommended.
