You can buy spare phone batteries on eBay for $2 each. Carry one or two around with you (they're small, of course, since the phones are thin to begin with), and you're set. You'll likely need extra chargers for them too, so a little more money spend there, but eBay provides there as well.
Of course, iPhone users (such as myself) can't do this because the battery can't be easily removed.
Making the phones a bit thicker probably couldn't hurt at this point either...
