How about upgrading Apple 6s to ios 1 1?

Apple 6s has been upgraded. The latest IOS 1 1 system does not support degradation.

How to solve

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!

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 ~

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.

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, turn it off! 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!
