Apple’s pushed a new iOS 16.1.2 update to iPhone users.
Like iOS 16.1.1, iOS 16.1.2 is a small point upgrade. The firmware brings important enhancements and unnamed security patches to owners of the iPhone 8, iPhone 8 Plus, and newer.
With that in mind, we want to walk you through everything there currently is to know about Apple’s iOS 16.1.2 upgrade for iPhone.
In this walkthrough we’ll take you through iOS 16.1.2’s changes, the software’s performance, iOS 16.1.2 problems, the iOS 16 jailbreak status, and more. We’ll start with some quick thoughts on iOS 16.1.2’s performance.
iOS 16.1.2 Review
If your iPhone’s currently running iOS 16.1.1, you’ll see the smallest iOS 16.1.2 download size.
The iOS 16.1.2 download size depends on your iPhone model and the version of iOS it’s currently running. So if your iPhone is running an older version of iOS, you’ll see a bigger download because your iOS 16.1.2 update includes the changes from the iOS updates you skipped.
If you’re moving up from iOS 16.1.1, the iOS 16.1.2 installation process should take less than 10 minutes to complete. It took about seven minutes to install on an iPhone 12 Pro that was previously running iOS 16.1.1.
We’ve been using iOS 16.1.2 on an iPhone 12 Pro for several days now and here’s what we’ve learned about the software’s performance thus far:
- Battery life is currently stable.
- Wi-Fi connectivity is fast and reliable.
- Bluetooth is working normally.
- GPS and cellular data are both stable.
- Third-party apps including Netflix, Dark Sky, Twitter, Slack, Asana, Gmail, Chrome, and Spotify are all working fine at the moment.
- First party apps like Safari, Podcasts, and Calendar are also running properly.
- iOS 16.1.2 feels as fast as iOS 16.1.1 did.
If you’re running into bugs or performance issues on iOS 16.1.1 or an older version of iOS, you might want to install the iOS 16.1.2 update on your iPhone right now.
