Thanks, both are very interesting.

As I noted upthread, I have not had any serious issues with battery life on my iPhone (except one self inflicted case where I let it get about 5 deg F cold). It turns out I have (inadvertantly) been doing several of the things noted in both links which tend to prolong battery life.

The claim that "iPhone batteries are crap" is considerably overstated, in my opinion. Used properly, mine works just fine, thank you.
