Mixpanel: iOS 10 reaches 48% adoption after two weeks, lagging slightly behind iOS 9 a year ago

Context & Ripple Effects
Two weeks ago Mixpanel clocked iOS 10 at 14.45% in its first 24 hours, ahead of iOS 9's 12.6% debut — so today's report that the new release sits at 48% after a fortnight, slightly behind iOS 9's pace at the same point, marks a reversal of that early lead.
The reading matters because Mixpanel has become the de facto public scoreboard for iOS upgrades: the same panel later tracked iOS 14 outpacing iOS 13 five days in, and a decade on, adoption numbers are contested enough that Apple publishes its own counts alongside third-party estimates like Wikimedia's versus Statcounter's.
First-order effects
- Developers can now treat iOS 10 as the majority install base and shift minimum-version targets accordingly, with Mixpanel's panel the reference they cite for timing.
Second-order effects
- Every release now gets judged against its predecessor's curve within days, putting pressure on Apple to keep auto-update momentum high whenever a new version trails — a dynamic that recurs in later cycles like iOS 14 versus iOS 13.
Third-order effects
- If the pattern holds, adoption measurement itself fragments: by the iOS 26 cycle, Wikimedia and Statcounter disagreed sharply and Apple slowed auto-updates, forcing the company to publish official figures (79% of all iPhones) rather than rely on third-party panels like Mixpanel.
The trend: iOS adoption is getting slower and harder to measure, with the scoreboard migrating from third-party panels like Mixpanel toward contested estimates and Apple's own official counts.
