Well, hmm - is it? I'd naively imagine cobalt content is proportional to battery size, and while Apple sells a lot of devices they aren't large energy-hungry ones. Surely far more of the world's battery production (by watt-hours or kg, take your pick) goes into cars and grid storage than iPhones?

When run at full-steam, MacBooks, iPads and iPhones can churn significant amount of data for their sizes, and use significant amount of energy. The batteries sold by Apple are pretty dense for their sizes, and they sell a lot of them. It will definitely add up.

  Sure, I'm not hating on Apple - it's a perfectly reasonable thing for them to do. But I'd question how much of global cobalt production was ever going into macbooks/iphones rather than electric cars, lawnmowers, hoovers and whatever else. This sets a good precedent but we'd need other manufacturers (who I'd guess are more cost-conscious) to follow suit before it changes much.

Apparently an iPhone uses about 8 grams of cobalt. Considering how many units are shipped annually, that adds up to quite a lot actually.

The applications that don’t need the highest energy density are shifting away from cobalt.

Hmm… > 232 million iPhones, 61 million iPads and 26 million Mac and MacBook… - (last year) https://www.businessofapps.com/data/apple-statistics/ 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.

  >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'.
