It seems that iCloud is still a drainer (well any such service would be) ... I recently migrated my email to Zimbra and setup exchange for Email/Contact/Calendar/Reminder and turned off these in iCloud ... and voila ! ... not only did battery improve (higher standby+usage) the whole email experience became better ...
Apple really needs to get iCloud Email upto standard!
