Does # of installed apps affect battery life?

[piblondin]

I'm curious to know if anyone have done tests to figure out if the number of apps installed on your phone has any noticeable affect on its battery life. Does having more apps decrease battery life in any observable way? Thanks!

There's no reason the number of apps would affect your battery life.

Regardless of how many you have on your iphone or touch, you can only run 1 at a time so I don't think it will be much of a battery life factor.
