iOS 12.1 Reviews
The iOS 12.1 update is a sizable download for iOS 12.0.1 users. If you’re currently running iOS 12.0.1, you’re looking at a 470MB download.
If your device is connected to a fast Wi-Fi network you should be able to download the iOS 12.1 update in less than five minutes.
As for the installation, it should take less than 10 minutes to complete. It took right around six minutes to install on the iPhone X and about seven minutes on the iPhone 5s.
If you’re currently running iOS 12.0 or an older version of iOS 11, you can expect your iOS 12.1 download and installation to take a longer. This is because the features and fixes from the updates you skipped are baked into your iOS 12.1 update.

iOS 12.1 Update: What’s New
The iOS 12.1 update finally brings Group FaceTime calls to iPhone, iPad, and iPod touch. It also makes the following changes to Apple’s FaceTime service:
- Automatic detection of active speakers: FaceTime uses on-device intelligence to display the most prominent speakers on the call, automatically highlighting the current speaker by bringing them to the forefront. It automatically sizes each person’s image depending upon how active they are in the conversation, based on duration of speech, volume and even motion. Participants who are not active will appear at the bottom of the screen until they speak. A simple tap also brings a participant front and center.
- Ringless notification: When calling more than one person, FaceTime displays a notification that lets you instantly join a call without being disruptive.
- Messages integration: Group FaceTime is integrated into the Messages app, making it easy to start a Group FaceTime right from a group iMessage chat. If people in a conversation have already started a FaceTime session, Messages shows the active call in the conversation list and inside your conversations.
- Private: All FaceTime conversations, both one-to-one and multi-person, are encrypted end to end so they remain private and viewable only by the participants.
iOS 12.1 includes a new feature for the iPhone XS and iPhone XS Plus.
Apple’s flagships come with a Portrait Mode feature lets you quickly adjust field of view. iOS 12.1 improves this feature with a new live preview that lets you sharpen or blur the background in real time via a slider tool. It’s comparable to the Live Focus feature on the Samsung Galaxy S9 and Galaxy Note 9.
The iOS 12.1 update addresses the “BeautyGate” issue where the iPhone XS and iPhone XS Max apply a skin-smoothing filter to photos making them look unnatural.
iOS 12.1 brings new emoji characters to the iOS keyboard and the list includes a kangaroo, a peacock, a parrot, a lobster, a mango, lettuce, a cupcake, a moon cake, and many more. There are over 70 new emojis inside iOS 12.1.
Unfortunately, users that aren’t running iOS 12.1 won’t be able to see them when you send them inside iMessages and text messages.
Here’s everything else on board iOS 12.1:
- Dual SIM with eSIM which allows two numbers in one device for iPhone XS, iPhone XS Max, and iPhone XR
- Improved cellular connectivity for iPhone XS, iPhone XS Max, and iPhone XR
- Ability to change or reset your child’s Screen Time passcode using Face ID or Touch ID
- Fix for an issue where the sharpest reference frame was not always selected in front-facing photos for iPhone XS, iPhone XS Max, and iPhone XR
- Fix for an issue that caused messages to be merged into one thread when two users were signed in with the same Apple ID on multiple iPhones
- Fix for an issue that prevented some voicemails from appearing in the Phone app

- Ability for Battery Health to inform users that it is unable to verify if a genuine Apple battery is in iPhone XS, iPhone XS Max, and iPhone XR
- Improved reliability of VoiceOver in Camera, Siri, and Safari
- Fix for an issue that could cause MDM Device Enrollment to report an Invalid Profile error for some enterprise users
References to Apple’s delayed AirPower charging mat have been discovered in the iOS 12.1 beta, a sign the company is still working on the device.
It’s still unclear when the company plans to release AirPower and there’s a good chance the launch gets pushed into next year.
Apple’s rolled out a new version of iOS 12.1 to the iPhone XR, the colorful 6.1-inch LCD model it launched in October.
The new iOS 12.1 firmware for the iPhone XR has build number 16B94 which is a little bit different from the update’s original 16B93 build number.
It’s unclear what’s on board, but we assume it includes additional bug fixes for the device.
If you already installed iOS 12.1 on your phone you won’t see a new update. This new build is only for people who are moving from iOS 12.0.1 (and below) for the first time.
iOS 12.1 Jailbreak
Jailbreak developers haven’t released anything for iOS 12 or any of Apple’s newer iOS 11 updates. The only way you can jailbreak a device is if it’s running an older version of iOS 11. Unfortunately, there’s no way to downgrade.
We haven’t heard or seen any iOS 12.1 jailbreak news so current and prospective jailbreak users should avoid the update when it arrives.
For more on the iOS 12 jailbreak, take a look at our guide.
Apple’s already confirmed the next version of iOS 12 and the iOS 12.1.1 update is now in beta ahead of an unknown release date.
iOS 12.1.1 looks like it’s a point release which means it probably won’t come with a long list of new features. With that said, it should bring several important bug fixes and security patches.
The iOS 12.1.1 update is next in line, but Apple might be cooking up another milestone upgrade for 2018.
The company released iOS 11.2 in December of 2017 and iOS 10.2 in December of 2016 so we could see iOS 12.2 arrive before the end of the year.
If an iOS 12.2 update is indeed on the way, be on the lookout for a beta in November.
