Does iPhone 6S upgrade IOS 11.3 card? IPhone 6S upgrade IOS 11.3 detailed experience

4hw.com.cn: at present, Apple has pushed the official version of IOS 11.3 to all models supporting IOS 11. Many old device users, such as iPhone 6S, are still waiting. Although IOS 11.3 has given users the option to reduce the frequency, many users are worried that the old device will get more cards after upgrading due to the chicken thief's apple. Is IOS 11.3 upgraded by iPhone 6S? Let's take a look at the iPhone 6S upgrade IOS 11.3 official experience.

1、 The frequency reduction control switch is not a button that users can switch back and forth

In fact, the frequency reduction control switch of IOS 11.3 is not a button that users can manually switch back and forth at will. What we need to know is that the frequency reduction control switch of IOS 11.3 is in the disabled state after upgrading to this version of the system at first. In other words, when your iPhone is not shut down unexpectedly, the frequency reduction control switch of IOS 11.3 may not be turned on for a long time. On the one hand, the battery of iPhone is running normally; on the other hand, it means that the battery performance indicators of iPhone do not trigger the critical point set by the system. In short, after the update to IOS 11.3, you will not see the frequency reduction control switch immediately, unless the iPhone is turned off unexpectedly.

Speaking of this, Apple has explained the problem of frequency reduction control switch earlier. Maybe some iPhone users didn't see it in time.

2、 When the iPhone is shut down unexpectedly, the frequency reduction control switch can be triggered to enable

Moreover, when the frequency reduction control switch of IOS 11.3 is enabled, iPhone users can completely see the previously invisible function options. For example, you can turn off the frequency reduction control by yourself or turn it on manually. However, as apple described in the past, if iPhone users choose to turn off the frequency reduction control switch, there will be a high probability of the iPhone's automatic shutdown.

As a user, there will be two ideas at that time: first, continue to turn on the frequency reduction control switch to keep the iPhone running normally; second, go to the apple store to replace a new battery after sale to artificially improve the battery performance. Of course, the above interpretation is based on the unexpected shutdown of iPhone.

3、 After two conditions are met, the frequency reduction control switch cannot be manually enabled again

Before the iPhone is turned off accidentally, you need to know that if you meet two conditions: 1. Your iPhone Battery can't reach the peak power; 2. You feel that the frequency reduction control switch of IOS 11.3 is not comfortable by default, which leads to the active shutdown of the function. The frequency reduction control switch can't be turned on manually again.

Then how can the frequency reduction control switch be enabled again? The only way to do this is to automatically shut down the iPhone in case of an accident. When the frequency reduction control switch of IOS 11.3 is enabled again, it will naturally return to the situation described above: that is, the system will provide the option to disable this function.

In addition, iPhone users should pay attention to the fact that when the frequency reduction control switch in IOS 11.3 is enabled, it can effectively prevent the phone from shutting down accidentally; otherwise, the situation that users encounter unexpected shutdown will increase. In other words, the main purpose of adding the frequency reduction control switch is to let users know what kind of state their iPhone is in.
