Apple’s released a brand new iOS 12.5.4 update for older iPhone, iPad, and iPod touch models.
iOS 12.5.4 is a point update and it’s an important release for those still hanging onto the iPhone 5s, iPhone 6, iPhone 6 Plus, original iPad Air, iPad mini 2, iPad mini 3, and sixth-generation iPod touch.
If your iPhone or iPad is currently running iOS 12.5.3, you’ll see a small download. If your iPhone or iPad is running an older version of iOS 12, your iOS 12.5.4 update could be bigger because the changes from updates you skipped are baked into the software.
In this guide we’ll walk you through the most important things to know about Apple’s iOS 12.5.4 update for iPhone, iPad, and iPod touch.
Our guide will take you through the iOS 12.5.4 update’s performance, the current state of iOS 12.5.4 problems, some places to find feedback about iOS 12.5.4’s performance, the iOS 12.5.4 jailbreak situation, and more.
We’ll start with our impressions of iOS 12.5.4’s performance.
iOS 12.5.4 Review
If you’re moving your iPad or iPhone from iOS 12.5.3 to iOS 12.5.4, you’ll encounter a small download. If you’re running an old version of iOS 12 on your device, the iOS 12.5.4 download size could, again, be larger.
If your device is currently running iOS 12.5.3, the iOS 12.5.4 installation should take 10 minutes or less. It took about eight minutes to install on an iPhone 5s.

iOS 12.5.4 Update: What’s New
The iOS 12.5.4 update brings three important security patches to older devices. You can learn more about these fixes on Apple’s security website.
iOS 12.5.4 doesn’t have any known bug fixes or features on board.
iOS 12 Jailbreak
You can jailbreak newer versions of iOS 12, but it’s unclear if you can jailbreak iOS 12.5.4.
The developers behind the “unc0ver” jailbreaking tool for iOS have released a version 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 12.5.4 and stay put on whatever version of iOS your device is currently running.
We’ll let you know when we learn more.
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.
It’s also worth noting that all devices compatible with iOS 14 and iPadOS 14 will make the move to iOS 15 and iPadOS 15. Devices stuck on iOS 12 won’t make the move to Apple’s new operating systems.
