There are really two questions that I have about this. - Does the standard Gmail application that comes with the phone (not the email app) utilize polling on a set schedule, or is it set to automatically push messages to the phone as soon as they hit the Gmail server? I have noticed that what it does seems to correspond to my Google Account Settings (and what I have checked). Specifically, when I check off the "Sync Gmail" feature, I seem to get my Gmail emails on my phone in real time. Does this mean that checking this option allows Gmail to "push" emails to my phone, or is it simply polling at very frequent intervals? - Which, in your experience, uses less battery: setting the phone to poll for e-mails every 30-60 minutes, or simply having the server "push" the e-mails straight to the phone? Also, does "pushing" e-mails work when Syncing is turned off (via the Power Control widget)? Basically I'm trying to find the most efficient combo that would allow me to receive my e-mails in a timely manner, while maximizing my battery life. Thanks in advance for your advice.
