Buy a refurbished Samsung Galaxy S20 SIM-free with 85%+ battery health, 12-month warranty, 45-day returns and fast UK delivery.
There's a version of the smartphone story that nobody tells often enough: the one where you buy something older, well made and properly checked over, and it turns out to be everything you needed all along. The S20 is that phone. Fast enough for everything daily life demands. Camera good enough to capture the moments that matter. Display bright, fluid and genuinely lovely to look at.
The world doesn't need you to have the latest phone. It just needs you to have one you're happy with. The refurbished S20, bought from somewhere you can trust, might be exactly that.
Every refurbished S20 we sell at The Big Phone Store is tested and graded in-house: data-wiped, battery checked, unlocked and covered by a 12-month warranty. Older, honest and absolutely still got it.

A refurbished Samsung Galaxy S20 is professionally prepared before sale. A typical used Samsung Galaxy S20 from a private seller may look cheap, but it can come with unknown battery health, unclear history and no useful warranty.
Professionally Refurbished | Typical Used Phone |
90+ point testing before dispatch | May only be briefly checked |
Minimum 85% battery health | Battery health may be unknown |
Professionally data-wiped | Data removal may not be complete |
12-month warranty included | Usually no warranty |
Clear cosmetic grade | Condition can be unclear |
Network and history checks completed | Hidden finance or network risk may remain |
Yes. Refurbished is usually safer because the phone is tested, graded, data-wiped and sold with a warranty and returns process. A private used Samsung Galaxy S20 may look like the cheapest option, but you often lose battery checks, support, history checks and a clear route back if something goes wrong.
Every refurbished Samsung Galaxy S20 we sell is fully functional. The grade describes cosmetic condition, not performance.
Like New: Best for the cleanest look and 100% guaranteed battery health
Pristine: Best for excellent condition with very light signs of use
Very Good: Best for smart savings with minor cosmetic marks
Good: Best for the lowest price if visible wear does not bother you
“The S20 is a great value choice because it gives buyers a sharp QHD+ screen, 5G and expandable storage at a very low refurbished price. On older models, battery behaviour, charging and screen quality checks are especially important.” - The Big Phone Store Refurbishment Team
Every refurbished Samsung Galaxy S20 comes with at least 85% battery health as standard. This is especially important on older models, where a private-sale phone may have a tired battery with no reliable test result.
Choose a Like New Samsung Galaxy S20 if you want 100% guaranteed battery health. This is the best option if you use your phone heavily for maps, photos, work calls, social media, streaming or long days away from a charger.
You will get at least 85% battery health as standard. If you choose a Like New refurbished Samsung Galaxy S20, you get 100% guaranteed battery health. For older Galaxy models, Like New is the strongest choice if battery life matters most.
