How to Recycle a Samsung Samsung Galaxy S21
If trade-in value is below £20 / $25 - or the device has a swollen battery, cracked screen with internal damage, or won't power on - recycling is the responsible end-of-life route.
The fastest free option for a Samsung device is the manufacturer programme: Samsung Recycling. Free mail-in or carrier-partnered drop-off. All Samsung products.
Free options that work for any smartphone:

What's Inside (Recoverable Materials)
A modern smartphone contains roughly 0.034g gold, 0.34g silver, 0.015g palladium, 15g copper and 16g aluminium. Total recoverable raw-material value is around $1-$3 per device at 2026 commodity prices. Lithium-cobalt batteries are 30-50g and require separate processing.
The UN Global E-Waste Monitor 2024 estimates that the raw materials in global e-waste were worth $91 billion in 2022, with only 22.3% formally recycled. Every device sent to certified recycling closes a small part of that loop.
Fair-condition trade-in is around $50. Small repairs (battery, screen) at $40-$100 can lift the unit to excellent and double the resale value - worth doing if the device is otherwise functional.
Common failure modes for this generation: battery degradation below 80% capacity (cheap fix at any independent repair shop), screen damage from drops (out-of-warranty repair from the manufacturer is usually 2-3x what an independent shop charges), and water damage (rarely worth repairing - recycle and trade up).

Frequently Asked Questions
What is a Samsung Samsung Galaxy S21 worth in 2026?
In excellent condition, the Samsung Galaxy S21 trades in for $120-$160. In fair condition (screen scratches, battery health 80-90%), expect $35-$65. Quotes vary by service; check Decluttr, Gazelle and Back Market for live pricing.

Is the Samsung Samsung Galaxy S21 worth repairing?
It depends on what's broken. Battery replacement on the Samsung Galaxy S21 costs $40-$80 at an independent shop and is almost always worth it if the device is otherwise functional. Screen damage is more expensive ($150-$250) but still cost-effective if the device is less than 4 years old. Water damage is rarely worth repairing.
How do I recycle a Samsung Samsung Galaxy S21 if it has no trade-in value?
Three free options: (1) the Samsung manufacturer take-back programme (prepaid mail label), (2) Best Buy Electronics Recycling (drop-off, 3 items per day), or (3) Staples Electronics Recycling (no quantity limit). All three are R2 or e-Stewards certified.
Is it safe to sell or recycle a Samsung Galaxy S21 with personal data on it?
Only after a full factory reset. On the Samsung Galaxy S21, this clears the encryption key and makes the data unrecoverable to the next owner. Sign out of any cloud account first (iCloud, Google, Microsoft account), then perform a factory reset from the settings menu before shipping.
