Apple appears to be engineering a multi-battery architecture into a future iPhone, a structural change requiring significant redesign of the phone's internal layout and thermal management. The move targets either extended battery life without proportional thickness increases or the ability to swap batteries mid-cycle—both responses to persistent complaints that modern iPhones lack easy repair and power-capacity extension. If Apple ships this, it would reverse years of making batteries harder to access, likely driven by EU right-to-repair regulations or market pressure from competitors offering modular devices.
