I can't go anywhere without my iPhone charger. I'm charging it just as much as I'm using it. I don't know what happened to the battery for the iPhone 5 but it's not that good. I can update you guys with screenshots of actual battery usage if need be. Basically I wake up at 6AM, this phone needs to be charged before lunch. After lunch, it needs to be charged 3 hours later. And the usage isn't that heavy. Call time on this phone is 19 hours in it's entire lifetime.
