One of the best perks modern society has is the instant fulfillment of everything: one-hour home delivery, home office, ultra-fast charging of batteries of devices ranging from smart watches and phones to electric cars.

Electric cars and phones are not much alike, when it comes to battery management. The first have huge battery capacities and don’t ever fully charge nor discharge, have complex management and cooling systems, while the latter are mostly glass slabs with huge processing power and no cooling. What’s even worse is that they’re most of the time covered in a heat-insulating plastic cover. Why is that worse? It’s not for the phone’s aesthetics, obviously, but for the battery.
