iOS 16 - Everything you need to know

The iOS 16 upgrade is available for the Apple iPhone and brings new functions. But what do you need to know about installing the new operating system for Apple smartphones? On which models can it actually be played? And which of the announced functions will be delivered later with an update? I answer these and other questions for you here. In addition, I will always expand this post when new information is available or we have written a new guide on iOS 16. For example, you can already find a help article about an App Store bug here in the blog. But it is also about instructions for new functions.

Apple's iOS 16 iPhone operating system can be installed on compatible devices. A collective contribution for all guides, instructions, assistance and news on the new system for iPhones is to be created here.

What is iOS 16 and do I need it?

iOS 16 is the iPhone operating system that Apple announced at WWDC22 and made available for free download on September 12, 2022. It replaces the iOS 2021 presented and introduced in 15 on compatible Apple iPhones. 

It includes new design options, security options, features for the Camera app and Photos app, the Fitness app for iPhone without an Apple Watch, and more. In addition, it is always safest to have the latest version of an operating system installed. So even if you don't need individual functions, I would still recommend the update.

Which iOS 16 features will come later via update on the iPhone?

Both the presentation of iOS 16 at WWDC22 and the catalog presented by Apple with details on the Widgets update for lock screen, apps like Photos, Messages and Co. as well as innovations for security, the display of messages, the use of Live Text and other functions in the operating system of the iPhone and everything else are impressive. But the iOS 16 upgrade for the iPhone, which was rolled out on September 12, 2022, didn't bring everything with it. 

The Freeform app, live activities on the lock screen, sharing keys in the wallet, support for the smart home standard Matter, the shared iCloud photo library and more will come later via update. Again, there's a single, small feature here and there that's delayed. For the full list of announced but delayed features, follow the link below: These iOS 16 features will come to the iPhone later.

Which Apple iPhone models are compatible with iOS 16?

But which Apple iPhone actually gets the new operating system for 2022 and 2023 from Apple? Which models of iPhone can perform the upgrade described in this guide? We also have a contribution ready for this: Is my iPhone compatible with iOS 16? 

If you don't want to click every link in this post and jump back and forth for all the information, here's the list for a quick overview: iPhone SE (2nd Gen), iPhone SE (3rd Gen), iPhone 8 (Plus), iPhone iPhone X, iPhone XR, iPhone XS (Max), iPhone 11 (Pro / Pro Max), iPhone 12 (mini / Pro / Pro Max), iPhone 13 (mini / Pro / Pro Max), iPhone 14 (Plus / Pro / Pro Max). So basically all iPhones since 2017.

How can I install iOS 16 on my iPhone?

So how does a compatible iPhone user get to enjoy this or that new feature? This is basically very easy via the settings, which have the well-known gears as a symbol. Since the iOS 16 release on September 12, 2022, you will find a reference to the upgrade there. This can take some time, since several gigabytes have to be downloaded and then the innovations for each individual app and function have to be installed.

    Good day,
    in ios 16 how can I delete the calendar widget on the lock screen or put the calendar widget under the time?
    or I would like the calendar widget to be displayed under the time on the lock screen.
    How am I supposed to do that ?

    With kind regards,

      Hello Shervin,

      As far as I can tell, the day and date cannot be placed below the time, only above it. However, when customizing the lock screen, you can use the calendar widget to display the next entry/appointment there. In addition to a smaller display of day and date, other widgets (weather, moon phase, etc.) can be added above the time.

      Best regards

    Hi John,
    Thanks, I've been waiting for this. I noticed that the cellular has improved on my IPhone 14 Pro. Where I just had 3G, I now have LTE (e.g. in the supermarket). I continue to use exactly the contract that I used on the iPhone XS in the first week of September. Would it be worth switching to 5G? I live in Munich and use my smartphone rather averagely.

    Greetings to you and to the Sir Apfelot team

    • Johannes Domke says:

      Hello Horst,

      in a big city like Munich you could definitely benefit from switching to 5G, so the supply should be secured. But of course it depends on what kind of content you want to load via mobile data. Navigation, e-mails, iMessage and the like can also be easily implemented with 4G LTE. But I don't have any (personal) comparative data or experience, because I very rarely use mobile data and almost never use up my monthly quota of just 1 GB. I also only use it via 4G LTE for messenger apps and for navigating via map services.

      Best regards
