Ask people what happened to their last phone and most will tell you it is in a drawer. Not lost, not broken, not sold — kept, because getting rid of it took a decision nobody made. It is the single most common fate of a working handset, and it is the one that helps no one. A phone in a drawer is losing value every month: Handset prices fall steadily as newer models arrive. A phone kept for two years is often worth a third of what it would have fetched the week it was replaced. Nothing about it improved in that drawer; the market simply moved on without it. Meanwhile someone is buying that model new: Every working phone that stays out of circulation is one somebody else buys new instead. That is a fresh set of mined materials for a device that already exists, in good order, a few miles away. The materials are the part worth caring about: A smartphone contains cobalt, lithium, and rare earth elements pulled out of the ground at real cost. Recycling recovers some of it, but recovery is lossy and expensive. Reuse recovers all of it, because nothing is broken down at all. What actually to do: Sell it, trade it, or give it away — in that order of value to you, and roughly equal value to everyone else. If it is genuinely dead, take it to a certified recycler rather than a bin; the battery alone makes general waste a fire risk that has closed collection facilities. If you are trading it in, the number you are offered depends on condition, storage and whether the handset is network-approved. All three are things you can check in ten minutes before you start.
