Which mail setting will use less battery? Push or fetch?

Hey guys, so which setting for mail notifications will use less battery, fetch hourly or Push notifications enabled for mail?

Fetch (in theory) will use less but I don't have any issue with push on my 4 accounts that use it. Maybe I could get a few more minutes per day but I rather just get the email when its available.

Push in the long run - it only downloads mail when you receive a push notification for it.

Push :
server : "mail ************!"
iphone: "ok, lemme fetch content"

both go chillin until new email arrives to server

Fetch:
iphone : "yo server, any mail yet?"
server: "nope"
.. after 15min (or more, 15 min is minimal fetch time)
iphone: "yo server, any mail yet?"
server: "nope"
15 min
iphone: "yo server, any mail yet?"
server: "yeah, grab it now"
iphone: "k, downloading"
15 min
iphone: "yo server, any mail yet?"
server: "nope"

Now if you received a single email through the day, fetch will ask the email server every 15min, while push will notify the phone when there's something to get.

I get a lot of emails during the day so mentioning that, will fetch use less battery or push? I don't get just one or two emails a day, more like 90 emails a day

Very nice guide!

After using Push since the day I got my iPhone 4, I switched to Fetch Mail every hour –as well as for iCloud services since I don't really mess with those and I don't get much email– Battery didn't improve that much.

This is what I think comparing push and fetch (set at the 15 min setting):

If you have lots of email a day (say average 1 new email every 5-10 mins), fetch should use less battery than push because push will be notifying you for every single incoming email and turning on your home screen ( assuming default notifications settings).

If you only receive a handful of emails a day, then push will use less battery as it only does it's thing only when a new mail is in your inbox, and not every 15 mins 24 hours a day.

How can I enable push notifications only from emails from my VIP list people? Because I think that would be smarter overall

The settings are per account. That and something like VIP classification and all that happens once your device already got the email (via push or fetch or manually).

That's more or less it--mainly depends on how much mail you typically get and how often it comes in.

Now you might also think about priority of you needing to be notified about that email immediately (push) or response time doesn't matter (fetch).

I want push just from VIP contacts how do I do that?

As mentioned, not something you can do. You can perhaps set up some filtering on the server side of hour email account so that only VIP emails would go to your inbox and thus that's all you'd get notified about as far as new mail goes. But that's about as close as you can get to that.

I don't think that's possible to set in the Mail app.

If you get a lot of mail fetch is a better option as no matter how much mail you receive your phone will only wake up once every 30minutes - hour to fetch mail. Push will wake your phone every time a message is received.

Only if you have mail notifications set for the lock screen.

That's not what I meant by wake up. The cellular radio wakes up and connects to the mail server to check for mail.
