iOS 11.3 Beta 2 :new battery health features Feb 08, 2018

System in the 10.2.1 iPhone6, 6s, SE and other models. Battery loss in excess of a certain amount of premise, Apple to prevent automatic shutdown, will reduce the phone frequency, to prevent automatic shutdown. But the consequence is the processor performance is reduced, leading to the user in the actual use of the process will appear Caton, only to replace the new battery can be resolved.


Apple this move, causing a lot of dissatisfaction with Apple users, leading to the final solution to Apple, low-cost battery replacement. However, Apple users do not seem to buy it for this move.

Finally, Apple gives the final solution. In the upcoming iOS 11.3 Beta 2 release, Apple will add battery health features, also known as performance switches.

After upgrading to iOS 11.3, we can check the maximum battery capacity of the device in Settings> Battery> Battery Health (Beta). These messages describe the degree of battery degradation and tell the user if the performance management protection mode has been turned on (the so-called "down" mode).


Apple said that if the iPhone's battery can not provide peak power output, then performance management protection mode will limit the performance of the processor. Beta systems currently enabled on the iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, iPhone SE, iPhone 7 and iPhone 7 Plus enable performance management.

However, it should be noted that the performance management and protection mode will not be turned on from the beginning, but only when the device's battery provides the ability to provide the maximum instantaneous power to go down and the device first unexpectedly shuts down Enabled.

For down-conversion, Apple said their starting point is good, in order to ensure the normal use of battery users and performance, to avoid automatic shutdown. However, it is good to inform the user whether to choose to downgrade, within the user's knowledge. If you do not know the user within the scope of the user deprive the right to choose the frequency, which is deprived of the right to choose the user.

Finally, we found that this switch is not a switch that can be switched at will. If you disable the "down mode", probably can not be turned on, you continue to use the full version of the frequency at the same time may encounter unexpected shutdown problem. So this time Apple just gives us two options: "maximum frequency + may shut down unexpectedly" or "slow down and normal use." Of course, Apple has given us a better option before that is: replace the battery.

Replace what battery?

WST high capacity battery!
