Erm, you keep having a panel in the back through which the battery can be easily replaced; users buys a battery - you provided the full specs for to the market to avoid obsolescence, right - and replaces it when you warn "battery should be replaced; do you want to downgrade performance to extend battery life". Apple are served by keeping a closed ecosystem, making repairs only possible by licensed people, not enabling device longevity but instead fetishising updated hardware. Society should be punishing this sort of behaviour as it stands firmly against sustainable use of resources.
