The adoption rate of iOS 17 is around 23% after 18 days
And to make the adoption rate even worse than it seems, consider that iOS 17 was pre-installed on the millions of iPhone 15 series phones that have been sold giving iOS 17 a helping hand. While those refusing to update to iOS 17 are missing some of the bugs, they are missing out on some great features such as StandBy, which turns an iPhone into a limited “smart display” when the phone is plugged in and is in landscape mode.
Those holding off downloading iOS 17 are also missing the ability to leave video messages on FaceTime, monitor voicemail being left in real time with Live Voicemail, create Contact Posters, and use CheckIn to alert friends and family members when they arrive at a specific destination. And these are just some of the features available with the latest iOS build.
