Apple should embrace the Apple Watch as a notifications hub: allow third-party developers to use custom sounds alerts and/or haptic feedback patterns with notifications.

Jason Snell:

You may not remember this, but before the Apple Watch came out, there were many rumors that it wasn’t able to get through a day without a charge. It’s clear that Apple made battery life a top priority, perhaps even the top priority: This thing better last all day. And so everyone was incredibly conservative with power and memory.

The result: They overshot. Most of the people I know now report that they end their day with their Apple Watches reporting 40 or 50 percent of remaining battery life. Fegerighi admitted that there was a lot of extra memory and battery life available to them when building watchOS 3, because they overshot so much. And that’s why watchOS seems almost impossibly better than watchOS 2, given that it’s running on the same hardware.

Classic approach by Apple — starting too restricted but loosen up over time instead of starting too open and tightening up over time.

Huge props to Apple for showing their ability to correct course.
