Intuitively, I would expect that an in-house Apple technology like iCloud would lead to a better battery life when syncing mail/contacts/calendars/etc as compared to syncing the same material via ActiveSync to an Exchange (or Google, or Outlook.com) account.
I'm curious as to whether anyone has definitively seen this in their own experimentation. In searches, I've seen opinions that run the gamut -- some saying iCloud was better anecdotally, others saying no difference, others still attributing Safari tabs sync to worse battery life with iCloud.
