Email access issuess can cause short iPhone battery life
Authored by: operator207 on Jul 20, '09 08:21:54AM

My 1st gen iPhone will eat the battery pretty quickly, and has done so with every revision of the OS (jailbroken or virgin) when I check email using imap.

It will do this on the edge network, on wifi unsecured, wpa2 aes, or wep. I am sure doing a higher encryption will use the cpu more, hence causing a quicker draw. But the fact remains, if its using a network, cellular or wifi, it will drain the battery. If your email uses a secure connection, like ssl, I would imagine it will drain the battery quicker too. Though may be only shortening the life of the charge by minutes or seconds.
