According to 9to 5 Mac, the terminal which upgraded to iOS 11.3 initially "performance management" is disabled, but it will become effective when the battery can not output with peak power because "unexpected shutdown" occurs in the terminal about. However, if you open "Settings" → "Battery" → "Battery Health", it can be disabled even once it is valid.

If it is an iPhone you just bought, the battery performance indicated in "Battery Health" should be 100%, but if you use a terminal that has been declining battery performance for many years you will have a battery like a brand new There is a possibility that it can not be expected.

"Maximum Capacity" showing the battery performance of the terminal is 100% in the following image, "Peak Performance Capability (peak performance performance)" under it "Your battery supports normal peak performance as usual It is written "It is written.


However, when Maximum Capacity falls to 95%, under Peak Performance Capability, "This iPhone can not demonstrate the peak power required for the battery, an unexpected shutdown occurred.In order not to cause a shutdown again Performance management "The performance description will be activated automatically. When performance management is enabled, the CPU slows down to reduce the peak power according to the battery, but when you tap the "Disabele (invalid)" letter that you can glance ... ...


The screen changes as follows. Performance management is disabled. However, once disabled, you can not change the setting until the device shuts down again.


If the battery performance further declines, options such as battery replacement are indicated. It is said that this description appears when the battery performance becomes 80% or less, but it is still possible to disable performance management at this point.
