About this device
Same camera set as the S21 with a larger display and a much longer-lasting battery.
The Galaxy S21+ is sold as ex-UK stock — a pre-owned handset imported from the United Kingdom, graded honestly on appearance. Sealed units of this model are no longer produced, so anyone advertising one as new is worth a second look.
Every Galaxy S21+ we sell is diagnosed across 42 checkpoints before it is listed. The IMEI is verified against national and international blacklists, the battery is tested under load rather than just read off the software, and every unit ships with a 12-month GadgetDeals KE warranty.
Specifications: 6.7" Dynamic AMOLED 2X 120Hz Dynamic AMOLED 2X, Exynos 2100 with 8GB of RAM, Triple 12MP + 64MP tele + 12MP ultra wide on the rear and 10MP on the front, a 4800mAh battery with 25W fast + wireless, IP68 protection and Ultrasonic fingerprint.
Choose your storage, colour and condition above. If the exact combination you want is out of stock, join the waitlist and we will call you the day it lands — usually within two weeks.

Ordered on Tuesday, delivered Wednesday afternoon. The battery health matched what was listed and there was not a single scratch on the screen.

Battery is genuinely strong
Charged from flat to full in about an hour and it comfortably lasted the whole working day.
