Hmm…

> 232 million iPhones, 61 million iPads and 26 million Mac and MacBook…

- (last year) https://www.businessofapps.com/data/apple-statistics/

I'll assume the batteries are 8 Wh for iPhone, 30 Wh for iPad, 52 Wh for the Macs[0]:

= (232 * 8) + (61 * 30) + (26 * 52) = 5038 MWh = 5 GWh

Which is more than I was expecting, but at the same time Tesla is on track for 1.8 million cars this year at a minimum of 54 kWh each = 97.2 GWh

So, yeah; good on Apple, more of this please from other electronics companies, still tiny compared to automotive.

[0] plausible guesses only because I don't have a breakdown of sales by model and I don't care enough to go looking

>I'll assume the batteries are 8 Wh for iPhone

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)

Depends 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.

I didn't doubt the conclusion, just the estimate was extremely low, I'd just not call it 'plausible'.
