Apple Overhauls iOS 27 Power Management

Apple is planning a major internal code cleanup in iOS 27, according to a 9to5Mac report, targeting legacy code and redundant background processes. The cross-framework refactor — covering kernel scheduling, networking, and the graphics pipeline — aims to reduce CPU usage and improve battery life, with internal tests showing small single-digit screen-on gains and reduced standby drain; iOS 27 betas are expected after WWDC in June 2026.
