    I have tried to fix the bad sound in the edited video below, not
    perfect, but less horrible :-)

    So iOS 12 will be out September 17th, and many wonder... Will it ruin my battery life, or will it improve my battery life over iOS 11.4.1
    Since iOS 12 GM will be the same build that will be released on September 17th it is time to test it and see before you update.
    I try to figure that out by comparing iOS 12 vs iOS 11.4.1 in battery life using the battery life test of Geekbench 4.

    First I run the test on iOS 12, then upgrade to iOS 11.4.1 and run the full test once more, and then we compare the scores. All conditions kept the same in both tests. Room temperature 23 degrees celcius

    All phones used has fairly new batteries with minimum wear, and are not being throttled as shown in the video.

    The iPhone 6S are on TMSC chipset.

    Hope you enjoy the video.

    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. Show less
