8Wh is exceptionally low (even guessing), it's just 2.22Ah for a Li-Ion (cobalt based). IPhone battery is 3.2Ah ~ 11.5Wh.
52 Wh for the Mac; that's a rather low estimate for a Mac, it has 3 cells in series, likely 2 or 3 in parallel. 2.8-3Ah per cell (at 3.6 nominal voltage)
- ben_w 4y agoDepends on the model, the SE is 7.82 Wh and that model is still on sale. But even doubling the combined total, let alone a mere extra 3 Wh * 232e6 = 696 MWh = 0.7 GWh, Apple is still a small battery user compared to Tesla cars.
- xxs 4y agoI didn't doubt the conclusion, just the estimate was extremely low, I'd just not call it 'plausible'.
