What do you do to it?
You realize that you're not supposed to swim with it, drop it in your iced tea

or let it fall it in the toilet, right? Mine usually last the 2 years, or close enough to it that they let me get it for the renewal rate.
When my DH's stopped working last time (at almost 2 years) he'd dropped it on the ground one too many times and the ringer stopped working. He didn't think that mattered.

We waited until he was at the 2 year mark (a month or so later) and then went and got new phones.
