In addition, the update rate is yet another aspect that differentiates the two phones. The Galaxy S21 Ultra comes with variable technology ranging from 10 to 120 Hz, in order to adjust according to demand without consuming a lot of battery. The iPhone 12 Pro Max brings only the 60 Hz option.

However, the Apple smartphone took the title of the best screen in the world by the specialized website DisplayMate in November 2020. The device also comes with Ceramic Shield (ceramic shield, in Portuguese), which promises to be the toughest glass on the market against falls and scratches.

When it comes to design, the Samsung offers more rounded lines than those of the iPhone 12 Pro Max which is part of a more rectilinear format. The Galaxy S21 Ultra measures 165.1×75.6×8.9 mm for a weight of 227 grams which is not anything in a pocket against 160.8×78.1×7.4 mm and 226 grams for the iPhone 12 Pro Max which remains the world’s thinnest 5G mobile. It is available in black, white, gold or blue while the South Korean mobile is offered in different colors: black, silver and, exclusively on the manufacturer’s website, in titanium, navy and brown.

The screen of the S21 Ultra measures 6.8 inches in curved mode compared to 6.7 inches for the iPhone 12 Pro Max. Both benefit from an HDR-compatible AMOLED panel, but that of the Samsung offers a refresh rate of 120 Hz against half for the American mobile which would therefore offer less fluidity when scrolling pages, for example. The screen definition of the S21 Ultra is 1440×3200 pixels against 1284×2778 pixels at Apple.

On paper, the 3,689mAh battery of the iPhone 12 Pro Max seems to lag far behind the 5,000mAh of that of the Samsung Galaxy S21 Ultra . But that is without counting on the formidable optimization signed Apple which can boast of an autonomy in normal use of 20 hours where Samsung is limited to 14 hours . The situation is the same for streaming videos, but the reverse is true for a phone call.

There remains the question of the charging time, which is close to two hours for the iPhone 12 (with a normal charger) against 1:09 for the S21 . Apple advantage, unless you spend your life on the phone.

Note that no charger is sold with these phones which additionally support wireless charging. Finally, only the S21 Ultra can charge other devices.
