Magic Keyboard combines a sleek design with a built-in rechargeable battery and enhanced key features. With a stable scissor mechanism beneath each key, as well as optimized key travel and a low profile, Magic Keyboard provides a remarkably comfortable and precise typing experience. It pairs automatically with your Mac, so you can get to work right away. And the battery is incredibly long-lasting — it will power your keyboard for about a month or more between charges.11 Testing conducted by Apple in September 2015 using preproduction Magic Keyboard devices, firmware and software with shipping iMac systems. Testing consisted of full battery discharge while engaging the device on a paired iMac using automated equipment. Battery life depends on device settings, usage and other factors.
