Apple’s pushed a new iOS 12.5.1 update to older iPhone, iPad, and iPod touch models.

iOS 12.5.1 is a point update and it’s a very 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 iPhone or iPad is currently running iOS 12.5, 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 12.5.1 update might be larger because the changes from updates you skipped are baked into your upgrade.

With that in mind, we want to walk you through the most important things to know about Apple’s new iOS 12.5.1 update for iPhone, iPad, and iPod touch.

Our guide goes over the iOS 12.5.1 update’s performance, the current state of iOS 12.5.1 problems, places to find feedback about iOS 12.5.1’s performance, the iOS 12.5.1 jailbreak situation, and more.

We’ll start with some quick impressions of iOS 12.5.1’s performance.

iOS 12.5.1 Reviews

If you’re moving your iPad or iPhone from iOS 12.5 to iOS 12.5.1, iOS 12.5.1 requires a small download. If you’re running an older version of iOS 12, your iOS 12.5.1 download could be larger.

If you’re currently running iOS 12.5, the iOS 12.5.1 installation should take less than 10 minutes. It took about seven minutes to install on an iPhone 5s.

For more on the iOS 12.5.1 download and installation, take a look at our guide.

We’ve been using the iOS 12.5.1 update for several days now and here’s we’ve noticed about the software’s performance thus far:

Connectivity

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

Apps

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

Speed

  • iOS 12.5.1 feels as fast as iOS 12.5.

If you’re running into bugs or performance issues on iOS 12.5 or an older version of iOS 12, you’ll probably want to install the iOS 12.5.1 update on your device right now.

iOS 12.5.1 Problems

The iOS 12.5.1 update is tiny, but it could have a big impact on your device’s performance.

If you’re frustrated with iOS 12.5.1’s performance on your iPhone or iPad, note that you can’t downgrade to iOS 12.5. Apple has stopped signing on the previous version of iOS 12.

Apple isn’t signing on older versions of iOS 12 either. This means that once you move your iPhone or iPad to iOS 12.5.1, there’s no moving off it. Keep that in mind if you’re still lingering on older software.

iOS 12.5.1 Update: What’s New

The iOS 12.5.1 update brings a bug fix for COVID-19 exposure notifications. From Apple’s change log:

  • Fixes an issue where Exposure Notifications could incorrectly display logging profile language.

iOS 12.5 doesn’t have any known security updates on board.

iOS 12.5.1 Jailbreak

You can jailbreak newer versions of iOS 12, but it’s unclear if you can jailbreak iOS 12.5.1 right now.

The developers behind the “unc0ver” jailbreaking tool for iOS have released a new version, dubbed 5.0.0, that’s compatible with iOS 13.5 and most versions of iOS that fall between iOS 13.5 and iOS 11.0.

The jailbreak tool isn’t compatible with iOS 12.3-12.3.2 and iOS 12.4.2-12.4.5. So if you want to stick around on one of those versions, you’ll need to go another route.

For now, you’ll want to stay put on whatever version of iOS your device is currently running.

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.
