I have a Lumia 928 and a Hotmail account, if I have the settings set to "as item arrives" when checking email, will this drain my battery any faster than "every 15 minutes"?
If you put the settings "as items arrive", shouldn?t the phone connect to the server often, and then drain the battery more?
I'm in agreement with sven. "As items arrive" would have to keep a near constant connection back to the server.
