I deleted all mail accounts (5 of them) within the iOS mail app as that is the only source of mail on my phone. Today battery still at 62% from the 100% charge ... looking good 36 hrs on! (Update: 43 hrs now and still a respectable 40%.)Hmmm your experience of battery drain and being warm is similar to mine. Did you delete the 3rd party app emails too?
