iOS 9 Low Power Mode, is thought to increase the autonomy of the battery of iDevices by up to 3 hours in the moments when we have little energy available in the battery for use.
In iOS beta 9 2 the system also started working thanks to an update made to the benchmarking application Geekbench 3 we can now see what impact it has iOS 9 Low Power Mode, on the performance of the terminals.
On the left side of the image above you can see the performances 6 iPhone Plus cu iOS 9 without iOS 9 Low Power Mode, deactivated, while on the right side you see the result with the module activated, the difference being about 30%, quite large.
Repeating the test on an iPhone 5S proved that iOS 9 Low Power Mode reduces performance by 30% for users, so we are talking about a substantial decrease in operating frequency and performance to increase battery autonomy.
Unfortunately, the benchmark does not tell us how much iOS 9 Low Power Mode reduces the frequency after activation by users, but we can assume that it is reduced by a percentage of 30%, which corresponds directly to the decrease in performance .
According to the information provided by the Apple company, iOS 9 Low Power Mode, Low Power Mode, can be activated with full functionality only when the terminals have at least 20% of the battery available, so at a higher percentage you will not benefit from any functionality from it .
Apart from reducing the frequency of the processor to improve battery autonomy, iOS 9 Low Power Mode, Low Power Mode, also disables certain system services and background updates for applications, all to increase the autonomy by 3 hours.
Having said that, we now know what the "magic" behind iOS 9 Low Power Mode is, so you know that when activated you will have very low performance, but you will also have a much better autonomy.
