In my iOS 12 review from last month, here’s what I wrote about iOS 11’s slow adoption rate as it related to its performance:

While iOS 11 may go down in Apple software history as the touchstone of the iPad’s maturity, it will also be remembered as one of the company’s most taxing releases for its users. You don’t have to look far into the iOS 11 cycle for headlines lamenting its poor stability on older hardware, plethora of design inconsistencies (which were noted time and time again), and general sense of sluggishness – issues that may have contributed to a slower adoption rate than 2016’s iOS 10.

With iOS 12, Apple wants to rectify iOS’ performance woes, proving to their customers that iOS updates should never induce digital regret.

It sounds like at least part of Apple’s plan to focus on performance to entice upgrades to iOS 12 is working. Here’s Benjamin Mayo, writing for 9to5Mac last week:

Apple launched iOS 12 with much fanfare earlier this month but early adoption appeared sluggish. However, in the following weeks, iOS 12 adoption has actually outpaced iOS 11 now, according to data from Mixpanel.

iOS 12 is now installed on more than 50% of active iPhones, iPads and iPod touch devices. It took iOS 11 a month to reach this milestone; iOS 12 has achieved it in under twenty days.

The numbers have since been confirmed by Apple on its Developer site.

Anecdotally speaking, I’ve yet to hear of any friends or family members who updated to iOS 12 and regretted it. It’s almost as if Apple was able to somewhat slow down and ship a higher-quality iOS release that more users can enjoy and recommend to others. Or maybe it’s just the Memoji.
