iOS Battery Life Test / Battery Drain / Battery Performance

iOS Battery Life / Battery Drain / Battery Performance Test. With the release of iOS 17 we saw almost unprecedented bad battery life. Will iOS be the medicine to bring back good battery life to the iPhone? iOS was released September 21, 2023 This video was shot more than 24 hours after iOS was installed, normally I will let it sit for a few days to settle in, but thought I would give it a go with just 24 hours. I monitored the CPU it was idle for the last 2 hours before the test was started so nothing seemed to be going on on the devices. I will however run the rest again in a few days and update the scores here in the comments. 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.
