Glad to hear you got yours back to normal. When it first started happening after I upgraded, I read up on it, and a lot of reports said to expect degraded battery for the first few days at least while the email app caught up and reindexed all mailboxes and iCloud did a fresh backup of up of the existing data. I have about 6 email accounts on my iPhone each with gigabytes of data, so I happily put up with the heat and battery issues for a while. But nearly two months later, the problem continues unabated. The heat is a real worry as it is too uncomfortable to have in my pocket anymore (the metal edges become almost too hot to touch), and I am wary of charging it when I am not nearby to monitor for any problems (oddly - it doesn't seem to heat up so much when charging, but I want to be 100% sure).
