Join this channel to get access to perks: iPhone 15 Battery Life / Battery Drain / Battery Performance Test on iOS , 17.3 and iOS This video was shot more than 24 hours after each of the iOS installations, this is to ensure that all background processing has finished. This was done by monitoring the CPU activity for the last 2 hours before the test was started. Before the test was run the devices were set to 25% display brightness, auto brightness has been disabled, all devices use same settings, and are connected to the same access point. 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.
