After the news came out, all users have shouted apples Apple is really too thieves, not how kind.
And then, further news shows that the reason leading to the decline of the old iPhone performance is actually the battery life.If the remaining battery life less, iOS system will automatically reduce the processor, to save energy.
But then, domestic counterparts test shows that the battery remaining is actually not good on the iPhone's performance caused a significant impact, the real impact is larger is the remaining battery power. If the power is lower than a certain percentage, the system will automatically down.
Apple officials have now responded by saying it does limit the performance of some older iPhones and limiting the processor's peak performance can reduce energy consumption and thus prevent the old device from running out of battery power and shutting down automatically.
On the reasons for doing so, Apple said performance and battery life are important to users, Apple is to find a balance between the two.
In a cold winter, or because of the natural aging of the battery, the battery power will gradually decrease, which may cause iPhone trigger protection mechanism automatically shut down.
As a result, Apple has made this limitation on the iPhone 6, iPhone 6s and iPhone SE, with peak performance limitations added after the iPhone 7 was upgraded to iOS 11.2, and in the future, Apple will extend this capability to more models .
At present, Plus series models should not enjoy this treatment, after all, the battery capacity was originally larger, in theory, do not have to worry about the low power lead to automatic shutdown.
In short, Apple is for your good, the card is better than completely useless.
