    MISTAKE – ONLY for iPhone. Not iPad

    • Paul says:


      It’s unusual for Apple to release a bug fix update for iPhone, while also releasing an update to older iPads and iPhones, but not modern iPads… curious.

      • Rob says:

        Yeah – quite odd. I’ve heard a rumor – unsubstantiated, that this was to fix a battery drain issue.

        • Paul says:

          I saw that too. Curiously, the release notes in Japan and China mentioned a battery draining issue, but the release notes in the US and Europe are very generic without a mention of battery drain. It’s possible there was a regional issue in Asia, but it’s not known yet.

    There’s no update 17.2.1 for iPad OS.

    Only for iOS.
