Hi all- Out of curiosity is there any battery savings (or other inherent savings) in using a pre-set time to check Exchange email vs. Push? For example my corporate email is Exchange and my BlackBerry is set to push; on my N1 I have it set-up to check every 10 minutes. Would using Push decrease my battery life? Decrease my RAM? Any other downsides? On the flip side - are there any advantages to enabling Push? Thanks in advance!
