Apple has released a new lineup of Mac accessories - Magic Keyboard, Magic Trackpad 2, and Magic Mouse 2 - and thanks to a triplet of iFixit teardowns we get to see exactly what it is that make these devices tick.
First up on the autopsy table is Magic Trackpad 2.
This is a scaled-up implementation of the Force Touch technology that Apple uses in its newer MacBooks. It used four strain gauges to measure pressure and has a built-in Taptic Engine to create haptic feedback (fancy terminology for vibrations).
The device is powered by a 7.65 Whr rechargeable Lithium-ion polymer cell.
Next it's the turn of the Magic Keyboard to get the teardown treatment.
According to iFixit this is essentially a portable version of the keyboard found on the latest MacBooks, and features a reengineered scissor mechanism to provide excellent key stability.
The device is powered by a 2.98 Whr (less than half the capacity of the 6.55 Whr battery found inside the new iPhone 6s) rechargeable Lithium-ion polymer cell.
Last up, the Magic Mouse 2.
Not much change here, essentially a Magic Mouse with a 7.28 Whr rechargeable Lithium-ion polymer cell.
All three devices feature a Lightning port for charging and easy pairing, and are supplied with a Lightning cable.
Now if you currently run your peripherals on disposable alkaline batteries (give your head a shake if you do) then the built-in rechargeable battery will save you money and help save the planet. However, if you're like me and already run rechargeable batteries in your device (I use Panasonic Enerloop Pro batteries) then what this move means is the hassle of charging cables and a device that has a lifespan limited to the life of the battery.
