The scandal of iPhones batteries revealed at the end of last year is a controversy that Apple does not want to revive in any way. After users discovered that the company was quietly slowing down the performance of old devices to preserve their battery, a huge public relations crisis erupted in Cupertino and forced the giant to take a series of measures to curb it.
One of these measures is the resource Battery Health, present from iOS 11.3 and that allows users to monitor the cell’s level of integrity and when it should be changed. For older devices, the feature also has the extra option of turning off the performance management – that is, your iPhone’s processor will run exactly as it did when it came out of the box, but your battery may last less and the device may shut down abruptly if the charge level is too low.
Originally, this option was only available for the iPhones 6, 6 Plus, 6s, 6s Plus, SE, 7 and 7 Plus – not least because, at the time, the iPhones 8, 8 Plus and X were still too young to need something like this . Now, no more: with iOS 12.1, iPhones 8, 8 Plus and X they also gained performance management (and therefore the option to turn it off).
The justification is simple: with some appliances in the 2017 line already reaching their first anniversary, it is natural that their batteries begin to show capacity losses or other failures intrinsic to their operation. With the novelty, Apple can preserve the battery of devices and give users the option to turn off the feature for maximum performance at all times – which is exactly what it should have done from the start.
According to Apple, however, performance management on the latest iPhones may be less noticeable because of its more advanced internal components. See what she reported on this support page:
This performance management works by analyzing a combination of device temperature, battery charge status, and battery impedance. IOS will dynamically manage the maximum performance of some system components, such as CPU and GPU, to avoid unexpected shutdowns only if these variables require it. In this way, the device’s workloads will be automatically balanced, allowing for better distribution of system tasks, instead of fast, larger spikes in performance all at once. In some cases, the user may not notice differences in the daily performance of the device. The level of perceived change will depend on how much performance management will be required for a given device.
Therefore, when upgrading your iPhone 8/8 Plus / X to the new version of the system, assess whether things are running normally and, if you want, turn off the performance management feature.
Has anyone there noticed any difference?
