They could make an RTG battery out of Promethium-147, a beta-emitter with half-life of 2.6 years and history of use in nuclear batteries, or Iron-55, an x-ray source with similar half-life. That would be perfect and totally on-brand for Apple, as the battery would naturally force the phone to be replaced in 3 years, and they'd have a solid safety/security justification for why any repair or replacement must be done in authorized Apple stores, by authorized personnel, with authorized parts and equipment. In a store where you could, oh so conveniently, just buy a new iPhone.
