Michael 15 was bishop of Stratonikeia in Lydia; in 787 he attended the Second Council of Nikaia (the Seventh Ecumenical Council) and probably attended the last seven sessions, from 26 September to 23 November 787: Mansi XII 1102-XIII 486. He is not named in the list of those present at the first session. In the list of those present at the seventh session he is styled Μιχαὴλ ἐπισκόπου Στρατονικείας: Mansi XIII 369. Elsewhere he is styled Μιχαὴλ ὁ ὁσιώτατος ἐπίσκοπος Στρατονικείας or similar: Mansi XII 1102, XIII 144. At the second session he supported the traditional veneration of icons as described in statements from pope Hadrian I (Hadrianos 1) and condemned iconoclasts: Mansi XII 1102. At the fourth session he subscribed the statements read out from the Fathers in support of the veneration of icons: Mansi XIII 144. His name is missing from the list of those who subscribed the statement of the faith adopted by the Council at the seventh session, but he was present at the session and the omission is perhaps a textual error.
