As with other tests, smartphone batteries are tested in a laboratory using specialized equipment. DxOMark is said to account for about 100 parameters over 150 hours on a per-device basis. Experts evaluate the devices in three key categories:

  • Autonomy – how much a smartphone can work on a single charge in various scenarios, including watching videos, listening to music, playing games, making calls and others.
  • Charging – how long it takes to charge from 0% to 80%. In addition, the difference between when the smartphone shows 100% charge and when it actually stops accepting energy is taken into account.
  • Efficiency – how much power the device consumes when charging or discharging.



The DxOMark website already provides scores for 17 different smartphones. The leader of the rating is now considered the Samsung Galaxy M51, equipped with a 7000 mAh battery. It scored 96 points for autonomy, 61 for charging and 87 for efficiency. His overall score is 88 points. For comparison, the iPhone 12 Pro Max received 78 points, the Xiaomi Mi 10T Pro – 72 points, the OnePlus 8T – 71, the Samsung Galaxy S21 Ultra with a Snapdragon processor – 70 points, while the Exynos version received only 57 points.
