Dimension	What the research suggests	Sustainability takeaway
Recycling and disposal	Surveys consistently show storage is common, while recycling, resale, and trade-ins lag behind; one CNET survey found 39% recycle old tech, 29% stash it at home, 22% throw it in the trash, 24% trade it in, and 18% sell gadgets online[[cite:7]]. Another survey summarized in The Independent found 39% stored old devices, about 1 in 10 recycled them, about 1 in 10 resold them, and 9% threw them in the trash[[cite:8]].	There is real circular behavior, but a large share of gadgets still stays out of reuse and recycling streams[[cite:9]][[cite:10]].
Upgrade cycles	Smartphone replacement cycles have lengthened. CTA reports consumers expected phones to last nearly five years, with a device-lifecycle summary listing smartphones at 4.8 years[[cite:11]][[cite:12]]. SellCell reports a global smartphone upgrade cycle of 3.7 years in 2022 and 3.5 years in 2025[[cite:13]][[cite:14]]. For wearables, BGR cites a Clutch survey saying about 59% of wearable tech users upgrade every two to three years[[cite:15]].	Longer phone lifecycles are better for material efficiency, but faster wearable refresh cycles keep replacement pressure relatively high[[cite:16]][[cite:17]][[cite:18]].
Knowledge of sustainable materials in wearables	No directly matching recent survey was identified in the searched sources.	This part of the question cannot be strongly assessed from the current evidence set.
