Perhaps the worst thing about my iPhone 3G — if there is a worst thing about it — is the abysmal battery life. Given the way I use it — with 3G turned on, Bluetooth turned on, WiFi turned on, plus making and receiving calls all day long and often playing iPhone games or reading text between calls — it’s no surprise that even if my battery is fully charged at dawn, it is nearly depleted by mid-afternoon. I’ve got iPhone battery chargers everywhere — on my desk, on my nightstand and in my car — and I still run out of juice occasionally.
