iOS 14 Battery Life compared to iOS 13, 12, 11 and iOS 10…

Battery life is always a big concern for many users whenever a new version of iOS is released.But how big a difference in battery life is there between generations of iOS versions on the same device.

In this test I will try to show that by comparing 5 generations of iOS using Geekbench 4.

All devices have original Desay batteries with 100% battery health, confirmed in the video in the settings, except for iOS 10.3.3 which I confirmed using Coconut Battery for MacOS.

Before the test was run the devices were set to 25% display brightness, auto brightness has been disabled, all devices use the same settings, and are connected to the same access point, just to make it as level a playing field as possible.
