The Samsung Galaxy S10+ was the big-screen version of Samsung's 2019 flagship, and it is the one of the pair that has aged more gracefully. The extra body length buys a 6.4-inch Dynamic AMOLED panel and, more importantly, a 4,100mAh battery that gives it a fighting chance of lasting a day even now. The rear camera trio is identical to the smaller S10, so you get the same ultrawide, main and 2x telephoto range, while the front adds a second 8MP depth sensor for tidier portrait selfies. As a used or refurbished buy the appeal is the feature set Samsung has since abandoned: a headphone jack, microSD expansion up to 1TB, IP68 protection and reverse wireless charging for earbuds. The catches are real, though. The Exynos 9820 is well behind current mid-range chips under sustained load, and software support ended with Android 12 and One UI 4.1, so no new security patches are coming. Ceramic-backed 512GB and 1TB versions exist and are noticeably heavier than the glass models. It makes sense for someone who wants a large premium screen and expandable storage cheaply.
