Exchange - "As items arive" vs "Every X minutes" (battery use)

[Clocks]

Anyone seen a difference when changing the Exchange sync settings from "Every X minutes" to "As items arrive"?

I'm not one of the poor folks with horrible battery issues, and I easily get > 1 day of normal use, just wondering if this setting will put a noticeable drain on my battery,

The only difference I see is that I get no mail when I check "As items arrive". I let it poll every 10 minutes and, like you, I get more than a day out of the battery. I keep the charger handy just in case.

i noticed the same, i get nothing when i check "as they arrive" option. I have to do a manual refresh.

I use ActiveSync for my gmail, and I get items within seconds of receiving them in my gmail inbox.

gmail is push, you dont need active sync

I get my gmail messages instantly when set to as items arrive, but I cannot get photo attachments, when I try to open them, it says they are corrupted. I can set up my gmail with IMAP and the same emails with photos come through just fine, just not instantly like with exchange

If you want 'push' email with gmail and the native mail application, you need to use Google Sync (Gmail Sync). This is generally set up as an Exchange (ActiveSync) connection on handhelds. Otherwise you are likely using POP or IMAP access which is NOT push, it's fetch.

push = emails are updated on your mobile device, initiated by the server
fetch = your device gets email updates on a certain time interval configured on in the device settings

If you are using the GMail application, that is push. According to the chart at the link below, Google Sync

I definitely receive emails when I set it to "As items arrive". In fact my DI gets the emails faster than my work computer.

But after a full day the battery seems unaffected, so I'll leave it on "As items arrive".

I think that I get slightly better battery life using "every 5 minutes," but I haven't had enough time to truly test.

Also, I only get notifications of emails until I go to the application and let it refresh. They're not there immediately, but this could be due to how the phone is sleeping or some other issues. Again, I haven't had enough time to fully investigate these issues as much as I would like.
