Kornel@xek According to ifixit, S9 has 250mAh battery, which is about 1Wh.
For giggles, 1Wh relative to energy usage of an electric car gives about 6 meters of range.
Jake Robb@kornel @xek now I’m imagining someone pulling up to a charging station in their EV and the car dies just a few meters away, but they’re able to get that last bit by shunting power from their Apple Watch. Like on Star Trek, when they can just reallocate power from other systems and sources to wherever it’s needed.
