7 Things to Know About the iPhone 7 iOS 11.2.1 Update

Apple’s new iPhone 7 iOS 11.2.1 update isn’t a massive update, but it could have a significant impact on your device’s performance.

The company’s latest iOS 11 update is a maintenance upgrade which means it comes with bug fixes for the iPhone 7 and iPhone 7 Plus. Namely, a fix for HomeKit issues.

Apple’s intentions are good, but the update is already causing problems for many iPhone 7 and iPhone 7 Plus owners.

Early adopters are complaining about UI lag, battery drain, and issues with certain first and third-party applications. It’s difficult to predict exactly predict how iOS 11.2.1 will perform on your iPhone 7 or iPhone 7 Plus so you need to be careful.

If you’re coming to iOS 11.2.1 from iOS 11.2, your download should be a few megabytes. It’s a tiny download and it should only take you a few minutes to get it up and running.

If you skipped iOS 11.2, iOS 11.1.2, iOS 11.1.1, or iOS 11.1, your iOS 11.2.1 download will be much bigger and your installation will take longer.

    Good to get 3D touch app switcher back in the iOS 11.1. New emoji sets are good. The fluid wallpapers are so sleek I love the designs. And most important Apple Team has fixed KRACK WiFi vulnerability which was most important thing in this update. Overall I am really enjoying iOS 11 so far. Thanks for writing Adam really enjoyed your article.
