The Samsung GALAXY S21 Ultra has surprisingly good autonomy for the battery, managing to surpass the iPhone 12 Pro Max, Samsung GALAXY Note 20 Ultra, Samsung GALAXY S20 Ultra and iPhone 11 Pro Max, the result itself being a surprising one.
The Samsung GALAXY S21 Ultra also has one of the largest batteries among all the phones tested, but also a lower resolution than the iPhone phones, for example, and managed to surpass both of them, but in the case of the iPhone 11 Pro Max, the difference is not insignificant big.
The Samsung GALAXY S21 Ultra still has a set refresh rate of 120 Hz, 4 times higher than that for iPhone screens, and this is extremely important in regular use, but the big difference in battery capacity suggests that its new Exynos chip still does not have good energy efficiency.
