Apple has released the latest update to its iPhone software, iOS 18.2.1, which addresses minor issues from its predecessor, iOS 18.2. The new update is available for various iPhone models, including those from 2018 and later.
The update is designed to resolve bugs that caused unexpected battery drain, Face ID failures, and Wi-Fi connectivity issues. However, unlike the previous update, this one does not include any security patches.
Users can download and install the update by navigating to the Settings app, selecting General, and then Software Update. The update is relatively small in size, making it a quick process for users.
Apple has emphasized that the update is recommended for all users, indicating that the fixes are not solely focused on Apple Intelligence, but rather address broader issues affecting various iPhone models.
