Apple’s pushed a brand new iOS 12.5.3 update to older iPhone, iPad, and iPod touch models.

iOS 12.5.3 is a point update, but it’s an important upgrade for the iPhone 5s, iPhone 6, iPhone 6 Plus, original iPad Air, iPad mini 2, iPad mini 3, and iPod touch sixth-gen.

If your iPhone or iPad is currently running iOS 12.5.2, you’ll see a short change log and a small download. If your iPhone or iPad is running an older version of iOS 12, your iOS 12.5.3 update could be bigger because the changes from updates you skipped are baked into the software.

With that in mind, we want to walk you through the most important things to know about Apple’s iOS 12.5.3 update for iPhone, iPad, and iPod touch.

Our guide goes over the iOS 12.5.3 update’s performance, the current state of iOS 12.5.3 problems, places to find feedback about iOS 12.5.3’s performance, the iOS 12.5.3 jailbreak situation, and more.

We’ll start with our impressions of iOS 12.5.3’s performance.

iOS 12.5.3 Review

If you’re moving your iPad or iPhone from iOS 12.5.2 to iOS 12.5.3, you’ll encounter a pretty small download. If you’re running an old version of iOS 12 on your device, the iOS 12.5.3 download size could, again, be larger.

If your device is currently running iOS 12.5.2, the iOS 12.5.3 installation should take less than 10 minutes. It took about seven minutes to install on an iPhone 5s.

For more on the iOS 12.5.3 download and installation, take a look at our guide.

We’ve been using the iOS 12.5.3 update for a short time and here’s we’ve learned about the software’s performance thus far.

Apple isn’t signing on older versions of iOS 12. So if you’re running iOS 12.5.1 or older, approach iOS 12.5.3 with caution. Once you make the move, there’s no getting back.

iOS 12.5.3 Update: What’s New

The iOS 12.5.3 update brings two important security patches to older devices. You can learn more about those fixes on Apple’s security website.

iOS 12.5.3 doesn’t have any known bug fixes or features on board.

iOS 12.5.3 Jailbreak

You can jailbreak newer versions of iOS 12, but it’s unclear if you can jailbreak iOS 12.5.3.

The developers behind the “unc0ver” jailbreaking tool for iOS have released a new version, dubbed 5.0.0, that’s compatible with most versions of iOS that fall between iOS 14.3 and iOS 11.0.

If you’re jailbroken or want to jailbreak, you’ll want to avoid iOS 12.5.3 and stay put on whatever version of iOS your device is currently running.

We’ll let you know when we learn more.

What’s Next

We don’t know what’s next for iOS 12 users.

Apple hasn’t confirmed a new version of iOS 12 and there’s no guarantee the company will continue to provide owners of these devices with new software in the months ahead.

If you decide you want the latest features, you’ll need to upgrade to an iPhone or iPad model that’s compatible with iOS 14 or iPadOS 14.
