I have an iphone 3gs I stopped using this summer just due to the battery dying off. Wasn't going to pay the absurd rates Apple charges to get new batteries, especially when I could just get an iPhone 4 if I really wanted to for like $30 more.
I still try to use the thing as a groupon screen. The Android groupon app requires a persistent network connection to maintain the barcode, the iphone version downloads the page entirely and you can keep reopening it without a connection just fine.
One day I charged it for 6 hours from complete dead battery (I just let the battery die now rather than let it eat up electricity for no reason, I rarely use it) turn it on, put it in standby once I have the groupon loaded, and by the time I whip it out 3 hours later to show the barcode the screen blips on before the thing shuts off due to critical low battery. Had to sit in the parking lot for 15 minutes with a car charger to get the thing to hold the screen long enough to scan it.
The phone is only 3 years old, and the battery doesn't last 3 hours in standby anymore.
