The company has rolled out a security update (iOS 12.5.3) for iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air, iPad mini 2, iPad mini 3, and 6th-gen iPod Touch.

It’s recommended that you backup your data before updating. To update, go to the Settings app, head over to General, tap on Software Update on the next window and once your supported device is done searching for the update, you’ll find Download and Install at the bottom of the display. Tap on it and your iOS device will start updating. 

Also, remember to charge your device completely before updating or update while charging the device to ensure that the update doesn’t get hindered.
