Apple has recently rolled out the iOS 18.5 system update, addressing 31 security vulnerabilities. However, this release has sparked heated debate among iPhone users, with some reporting significant issues such as device overheating and accelerated battery drain following the upgrade. Notably, owners of models like the iPhone 15 Pro have encountered their phones overheating, occasionally leading to automatic shutdowns during gaming sessions, and experiencing rapid battery depletion even when the devices are in standby mode. In contrast, users of the iPhone 12 and 13 series have noted improvements in battery life and smoother overall performance post-update. To date, Apple has yet to issue an official statement or provide a resolution to address these reported concerns.
