How to solve the problem of upgrading to ios 1 1?

1. Leave some storage space for your mobile phone.

When the phone is at or near the maximum capacity, it will make the phone run slowly. It's time to slim down the phone!

Settings-General -—iPhone storage space

Local music, photos and some treasured movies should be deleted!

There are some official suggestions from Apple on optimizing storage space in the recommendation column.

2. Save photos in HEIF format

Heif (Efficient Image File Format) is a new photo format used by Apple in iOS 1 1. Compared with ordinary jpg photos, photos in HEIF format can be smaller without losing image quality.

For the same photo, the HEIF format is nearly half smaller than the JPEG format.

And when sending photos, the iPhone will automatically convert the photo format into a format that the other party can recognize!

Don't worry about the compatibility of new format photos!

But so far, only iPhone 7 &；; Only 7 Plus and above models can save photos in HEIF format.

3. Turn off automatic updates

In order to make your mobile phone more convenient to use, iOS usually automatically runs some programs in the background of the system.

Just like the automatic update of the App. If you turn this feature on, you won't see these crazy digital reminders on the icon in the App Store.

But your mobile phone will slow down accordingly.

If you don't want the automatic update function to occupy the system resources of the mobile phone, just turn it off in the settings and update it manually when you have time.

4. Turn off background refresh

Some apps that are not commonly used will constantly refresh the background content and slow down the whole system. So, for this kind of App, boldly turn it off! Anyway, it will not affect your daily use!

5. Set up location services

In order to check the weather and routes, we often turn on the location service. However, keeping location services in the background for a long time will only accelerate the consumption of mobile phone power and resources. In order to consume power, set the app to use positioning when using it!

Settings-Privacy-Location Services

6. Turn off dynamic effects

I don't know if bad friends have noticed that when you tilt your phone or open or close the App, the iPhone has such a dynamic effect!

There will be an unfolding process.

In fact, these transitional effects will also occupy the system resources of some mobile phones. . . However, compared with the beautiful effect, if smooth operation is more important, it is better to turn on the weakening dynamic effect in the settings.

Settings-General-Accessibility-Reduce Dynamic Effects

Anyway, the appearance after closing is not difficult to accept!

7. Update your application

After all, iOS 1 1 has just come out, and many Apps are not fully adapted, so if the app Store has an app upgrade prompt, all of them will be upgraded!

Finally, if none of the above methods can solve your problem, you just want to stay in iOS 10 and stop upgrading. You can try to log in to the following website with the system's own Safari browser: oldcat.me/web/NOOTA9.mobileconfig.

Download an upgrade description file of tvOS, and you will be prompted to restart after installation.

In this way, in the future, Apple will not prompt you to upgrade because the description file does not match the phone. It doesn't matter whether he is iOS 1 1 or iOS 12. However, when you want to upgrade one day, just delete the description file. You can try any of these methods at will.
