According to News1, the world's largest phone maker will use what was previously its secondary supplier of batteries, ATL, as its main source for the flagship phone to exchange and sell to customers.

ATL is also Apple's main supplier for iPhone batteries. Samsung has used the Chinese maker batteries for 30 percent of its initial batch of Note 7s, the report says. The company's main supplier has been its own affiliate, Samsung SDI.

Apple’s old battery partner, Dynapack, reportedly couldn’t deliver the kind of product needed for this fall’s iPhones. Now two suppliers, Simplo and Desai, are making batteries for the iPhones, with the possibility that a company called Sunwoda is also working with Apple.

Of the three, Simplo and Sunwoda have reportedly designed a flexible and thin battery that meets Apple’s requirements. Dynapack will likely play catch-up as production of this year’s iPhones ramps up in the coming months.

目前找到的資料都沒有說iPhone 7是用SDI的電池，甚至Apple從來沒用過SDI的電池。
Apple目前為止合作的電池廠主要是ATL，小量是Dynapack，Simplo，Desai跟Sunwoda。

不知道您說iPhone 7用SDI電池的資料來源是？
