iOS 13.3 Battery Life | Performance Test. Now also on iPhone 11 and 11 Pro

Hi all,
iOS 13.3 is out and a lot of people are worried if it will degrade the battery performance of their device if they were to upgrade.
I try to find that out every time apple release a new version of iOS by comparing the Geekbench test results from the previous release to that of the new release.
In this video I will be comparing iOS 13.3 to iOS 13.2.3.

How Geekbench works :

Geekbench 4 battery scores measure the battery life of a device when running processor-intensive applications. It provides a consistent workload to the device, and generates a Geekbench score by evaluating the amount of work that it is able to do while the battery is discharging and the amount of time it takes for the battery to discharge.

The battery benchmark can be run in Full Discharge mode, from 100% to 0% battery level, to provide a high level of confidence in a device's battery performance. The battery benchmark can also be run in Partial Discharge mode, for 3 hours. If the battery benchmark is stopped after 10 minutes, by the user or by the battery reaching 0%, then the result will be saved and can be uploaded. Battery benchmark scores gathered by any method except the Full Discharge mode provide a medium level of confidence in a device's battery performance, and longer tests are more reliable.

When comparing scores, remember that higher scores are better, and double the score indicates double the performance.
