Always-on Display is the primary driver of the smartphone’s battery life.

When choosing a smartphone, people often look at the battery capacity. In theory, the more mAh, the longer the device will last. There’s often a debate about whether it’s better to buy an expensive iPhone with a low battery capacity or a cheap Android with all 5,000 mAh.

Always-on Display is the primary driver of the smartphone’s battery life. This means that the user can see basic information such as battery level, time, notification icons and other applications. It turns out that despite the device’s price or its low price, on average, its battery life is cut by 4 times with the Always-on Display on. Probably not even lowering the refresh rate.

Note that the following smartphones participated in the DXOMARK test:.

  • Apple iPhone 14 Pro Max;.
  • Google Pixel 7 Pro;.
  • Samsung Galaxy S22 Ultra (Exynos);.
  • Xiaomi 12S Ultra.

DXOMARK results have resulted in the latest and top iPhone delivering the brightest picture compared to Android rivals. On the other hand, on average, they all have the same amount of autonomy cut. Here’s how long smartphones have lasted with the Always-on Display mode:.

  1. Google Pixel 7 Pro 139 hours (367 without it);.
  2. Samsung Galaxy S22 Ultra 136 hours (417 without);.
  3. Apple iPhone 14 Pro Max 122 hours (466 without);.
  4. The Xiaomi 12S Ultra is 103 hours (495 without).
