Apple’s released an iOS 12.4.5 update for iPhone and iPad models that weren’t updated to iOS 13 or iPadOS 13.

iOS 12.4.5 is a point update which means it’s a small 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 device is currently running iOS 12.4.4, you get the shortest change log and the smallest iOS 12.4.5 download.

If your iPhone or iPad is currently running an older version of iOS 12, your iOS 12.4.5 update might be a little bit bigger because you get the changes from the updates you skipped.

With that in mind, we want to walk you through the most important things to know about Apple’s new iOS 12.4.5 update for iPhone and iPad.

Our guide goes over the iOS 12.4.5 update’s performance, the current state of iOS 12.4.5 problems, places to find feedback about iOS 12.4.5’s performance, the iOS 12.4.5 jailbreak situation, and more.

We’ll start with our quick impressions of iOS 12.4.5’s performance.

iOS 12.4.5 Reviews

If you’re upgrading from iOS 12.4.4, you’ll see a tiny download. If you’re running an older version of iOS 12, your iOS 12.4.5 download will be a bit larger because, again, the changes from the updates you missed are baked into your upgrade.

If you’re currently running iOS 12.4.4, the iOS 12.4.5 installation should take less than 10 minutes. It took about six minutes to install on an iPhone 5s.

For more on the iOS 12.4.5 download and installation, take a look at our guide.

We’ve been using the iOS 12.4.5 update for several weeks now and here’s we’ve seen from its performance thus far:

Connectivity

Battery life is stable.
Wi-Fi connectivity is fast and reliable.
Bluetooth is working normally.
GPS and cellular data are both stable right now.

Apps

Third-party apps including Netflix, Dark Sky, Twitter, Slack, Asana, Gmail, Chrome, and Spotify are stable.
First party apps like Safari, Podcasts, and Calendar are running fine.

Speed

iOS 12.4.5 feels as fast as iOS 12.4.4.

If you’re running into issues on iOS 12.4.4 or an older version of iOS 12, you’ll probably want to install the iOS 12.4.5 update right now.

iOS 12.4.5 Problems

iOS 12.4.5 is a tiny update, but in some cases it’s having a big impact on performance.

We’re hearing about an assortment of iOS 12.4.5 problems including installation issues, abnormal amounts of battery drain, connectivity issues (Wi-Fi, Bluetooth, GPS), issues with first and third-party apps, UI lag, random reboots, and more.

The list of iOS 12.4.5 problems is extremely short right now, but we expect it to grow as more users move their device to the latest version of iOS 12.

If you run into an issue on iOS 12.4.5 please take a look at our list of fixes for the most common iOS 12 problems. We’ve also released some tips to help improve performance and tips to help improve iOS 12 battery life.

If you’re frustrated with iOS 12.4.5’s performance on your iPhone or iPad, note that you can downgrade to iOS 12.4.4. Apple’s currently signing on it.

Unfortunately, that will probably end soon. Apple recently stopped signing on iOS 13.3 so we expect the company to stop signing on iOS 12.4.4 in the near future. If you want to move back, you’ll want to do so in the near future.

Apple isn’t signing on older versions of iOS 12 so keep that in mind before you make your move from iOS 12.4.3 or below. Once you make the move to iOS 12.4.5, there’s no going back.

iOS 12.4.5 Update: What’s New

The iOS 12.4.5 update doesn’t bring any new features to the iPhone and iPad and Apple doesn’t list any new security patches in detail so it’s unclear what the update brings to the table.

iOS 12.4.5 Jailbreak

You can jailbreak iOS 12, but you’ll want to be careful with iOS 12.4.5.

Jailbreak developers released a jailbreak tool called checkra1n that’s compatible with iPhone 5s-iPhone X. It’s not compatible with newer iPhone models.

If you own an iPhone XR, iPhone XS, or iPhone XS Max, you can jailbreak iOS 12 using the Chimera jailbreak tool. However, your device needs to be running iOS 12.0-iOS 12.1.2. Unfortunately, there’s no way back to those updates.

What’s Next

We aren’t sure what’s next for iOS 12 users.

The company could decide to release iOS 12.4.6 down the road, but there’s no guarantee that happens. If it does, don’t be surprised if it rolls out alongside iOS 13.4 later this year.

German site iPhone-ticker.de claims Apple will host an event at the end of March with Tuesday with March 31st the likely choice. If that happens, iOS 13.4 will likely arrive in and around that date.

If another iOS 12 update is in the cards for iPhone 5s and iPhone 6 users, we’d expect a release in and around March 31st. So, if you’re seeing issues on iOS 12.4.5, you might be on your own for a few more weeks at least.

If you decide you want the latest iOS features, you’ll need to upgrade to an iPhone or iPad model that’s compatible with iOS 13 or iPadOS 13.
