I sync gmail with my touch pro using the imap idle protocol and flexmail. I can tell you with 100% certainty that manual pull every half hour saves battery life over an always on idle push connection...I just did testing on this last weekend actually...I even save battery life with 15min pull vs push...that said, I like push so I just deal with slightly worse battery life for the timebeing...really wish there was a battery stronger than 1500mah that still fit the thin profile of the stock back cover...btw, flexmail is a superior interface for either push or pull email on windows mobiles phones...other than chattermail, which I had on my palm treo 755p, I have never used anything better...
