So, after restoring my phone and re-downloading all my apps, I decided to try and use the standard Mail App instead of K-9 which I had been using. The UI is a little smoother. Anyway, I noticed that you can now have it check under 15 minutes. So I set it to 5, which is as close to "push" as I can think of. I noticed today that my battery was draining quicker than usual. Would checking every 5 minutes run the battery more than K-9's "push"? I was comfortable with K-9's push. Wondering if anyone else had this issue or thoughts on it.
