iOS 12.5 Battery / Speed Performance Test on iPhone 5S and iPhone 6…

iOS 12.5 Speed / Performance and Battery test. iOS 12.5 was released by Apple December 14th, at the same time as iOS 14.3 for the newer devices.

Apple now finally includes Covid-19 exposure notifications in the older iPhone 5S and iPhone 6 devices.

Good job Apple. It will be exciting to see if the addition of this feature comes with performance costs or impact to battery life.

That is what I look into in these videos.

As always I run the side by side comparison tests vs iOS 12.4.9 and then a battery drain test using Geekbench 4, to see if there are any changes again against iOS 12.4.9 Lets go ! Remember to subscribe, studies show that subscribers iPhones are faster than non-subscribers. Now you know. 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.
