Like most things in this cruel world, your iPhone's battery must die someday.
Unlike most things, it is easy to predict the exact date and time it will permanently crap out.
When the fateful hour arrives, you'll need to send your phone back to Apple and wait.
Who knows how long you'll be phone-less? Three days? A week? Yikes!
To help you panic, er, prepare, we have devised ... the iPhone Death Watch!

Simply go to http://www.pcmagutils.com/cgi-bin/countdown.cgi, enter the date you purchased your phone, and, based on our scientific calculations, we'll provide an estimate for the day your precious device's battery will bite the dust.
For added drama and a heightened sense of doom, we have included a second-by-second countdown clock.
Our methods for finding a date were simple: we used a fully-charged iPhone the way one typically would.
That meant four phone calls, between three and ten minutes each; listening to the iPod on a 40-minute commute to and from work; checking Google Maps at one point when we were lost on the way to a meeting; and checking e-mail a whole bunch of times over both Wi-Fi and EDGE.
The phone lasted about 30 hours. Counting in the four hours or so it takes to trickle-charge over a USB port, the iPhone gets about 34 hours, or roughly 1.5 days, per charge.
Apple says that after 400 charges, the phone will hold 80 percent of a charge. Alas, they wouldn't tell us any more than that. (When we inquired, they skirted the issue.)
Regardless, we'll push it a bit beyond 400 charges and say that you'll really feel like replacing your battery at 450 charges.
Thus, 450 x 1.5 = 675 days.
So, if you bought your iPhone at 6 p.m. on June 29, 2007, your phone will kick the bucket on May 4, 2009 at 6 p.m.
Until then, enjoy your iPhone. Or make our Death Widget your start-up page on your iPhone and live in constant fear of the dark date looming in your future.
