Some iPhone users are reporting issues with rapid battery drain after updating to iOS 26, with specific versions such as 26.2.1 and 26.5 also being linked to crashes, freezes, and connectivity problems. The extent of the problem and the affected versions are not entirely clear, with different reports citing different versions of the operating system. A fix for the issues has been discovered by at least one user, and a potential update, possibly iOS 26.5.1, may be forthcoming to address the problems.
