Consumables are readily replaced at low cost. Batteries (in phones/tablets) are essential central components.

If you need tools or instructions then the parts aren't really consumables.

Part of the issue is the trend of integrating parts that used to be easily replaceable. My first phone/laptop each had batteries that could be swapped in under 10 seconds with no tools. My latest do not.

Whole device is a consumable. Six months of usage and off to a landfill it goes.
