Almost nobody cares about saving batteries. Those are replaceable and cheap to replace every couple of years.

Innovating more battery life and leaving 20% battery life on the table sounds extremely pointless for what costs 20-30$ a year but lets you use the device all day instead of just shutting before the end of the day.

I'm an "almost nobody". I care about saving batteries. I get all the dead disposable vapes my friends will give me so I can recycle the batteries in them. Lithium is a limited resource and one day we're not going to have more to dig up out of the ground. There are others like me out there, I just need to find them.

Lithium is not a limited resource in the same way that Iron or Coal or Silicon are not limited. There is so much of it that we really cannot run out.

Cobalt, Neodynium and the other rare earth metals, though, those are highly valuable; and the processes to manufacture them are usually toxic. So do it for the rare earth elements, but don't do it for Lithium.

The lithium is not disappearing though.

At some point in the future, we can start mining old landfill.

But yes, it's easier (and more efficient) to recycle before putting them in landfill.

If you specifically seek out devices with cheap replaceable batteries, sure. But this isn't the case with a lot of devices.

The cost to replace the battery on iPhones, which most people would consider to be “difficult to replace” is only $100 directly from Apple. Really seems like paying an extra $100 every 2-3 years is a decent deal for something that has 20% more battery.

Replacing an iPhone battery is cheap, especially compared to replacing the whole phone: at the Apple Store it’s either $99, $69 or $49 and I’ve had other stores do it for like $40. That’s not too bad for a once every couple years cost.

Let the user choose! Some people tether their phone a lot and use the battery only when out. For them 80% max is OK.

My Oneplus 5T got replaced because it has a small crack in the screen so it's impossible to disassemble without breaking the screen. I used ACC to only charge that to 90% so I could get three years out of the battery instead of just two.

I'll probably get a fairphone next so I don't need to worry about this. But the people with glued-in batteries definitely have to.

most recent phones and laptops have batteries that require advanced tools and chemicals to remove and replace

Laptops also? I didn't realise it had gotten this bad anywhere but in Macbooks.
