On the Watch side of things, update 3.1 improves battery life but doesn't add any new features, according to release notes published on MacRumors. WatchOS 3.0 was a major overhaul and the latest update finesses some of its functions, squashing a bug that stopped the Watch Series 2 from charging fully, fixing another glitch that prevented Force Touch from working with some apps, and addressing one issue that made Activity rings disappear from the watch face. Also, the timer shouldn't notify users twice once it's finished anymore, Messages effects will work with Reduce Motion enabled and Watch wearers have the option to replay bubble and full-screen effects in Messages.

The Watch update is available across Series 2, Series 1 and first-generation models.
