I think it should be a requirement by these device manufacturers to make phones that will last at least a full day with average usage. I'm not a power user by any means on my phone, I don't spend all day incessantly checking emails and facebook updates like some of my friends do, yet my batteries never make it through a day and often times won't even make it through half a day. If I leave my house at 6pm and go visit my friend, while I'm there within two hours my phone will be almost completely dead.
