The iPhone sucks up battery like whoa. I plug mine in for half an hour or so every morning when I'm refreshing tabs on my desktop computers. If I had to go two days without charging, I'd be rationing usage. Can't speak to battery lifespan since my phone is only a week old... but I think batteries are only meant to outlast the phone's manufacturer warranty, really. Which does suck, but ensures that you'll renew your contract to get a discount on a phone. Bah.

I'm always disappointed that 95% of decaf teas are based in something other than black tea. I've taken to just buying bulk decaf English Breakfast from Whole Foods.
