MagyarSamsung Galaxy S21 Ultra with an Exynos 2100 SoC sinks in DxOMark's new battery
DxOMark has introduced a battery life element of its smartphone reviews. According to a blog post, the website bases its battery life findings on various situations, charging speed, and efficiency when charging/discharging. If you are interested in how DxOMark calculates its battery life scores, you can read its blog post here.
Currently, DxOMark believes that the Samsung Galaxy M51 has the best battery life of any smartphone that it has tested. The Galaxy M51 scored 88 points with its 7,000 mAh battery and Snapdragon 730G SoC, 2 points more than the Wiko Power U30. It is not all good news for Samsung, as the Exynos version of the Galaxy S21 Ultra 5G scores 57 points.
The difference between the Exynos and Qualcomm models is stark, as the latter scores 70 points in the same tests. Incidentally, the Apple iPhone 12 Pro Max scored 78 points, putting it fourth in DxOMark's smartphone leaderboard.
In our experience, the iPhone 12 Pro Max has much better battery life than the Galaxy S21 Ultra 5G (Exynos), despite its smaller battery capacity. We should stress that DxOMark values charging speed highly. The Pixel 5 scores poorly, for example, despite having excellent battery life. Presumably, DxOMark has marked the Pixel 5 down for its peak 18 W charging, which is lower than many of its contemporaries.
In short, we would take DxOMark's battery rating with a pinch of salt. As it explains, the final score does not represent a device's battery life, but also its charging speed and charging efficiency. If the score accurately reflected a device's battery life, then something like the Mi 10T Pro 5G would outscore the iPhone 12 Pro Max. The Galaxy S21 Ultra 5G (Exynos) has relatively poor battery life whichever way you cut it, though.
