Why is Apple's mobile phone so slow?

The following reasons may slow down the download speed of your mobile phone:

1:WiFi itself is small and the network speed is not fast.

2. Other devices connected to the same WiFi on 2.iPhone are downloading things, which takes up too much bandwidth.

3. System problems, which sometimes appear in systems above ios8.

4. If you download from the mobile app store, it will be slow if it is 3G4G, but it will often fail because the download speed cannot be provided normally, but you can't cancel it.

5: It is suggested that you replace 3G and 4G calling cards and improve the download speed of mobile phones.

6: 6: The App Store itself will download the software. By default, the software will not connect to the local server, so the speed will inevitably be delayed. I suggest you form a good habit of using mobile phones.

7: You can also restore the telephone network settings, restart or shut down.

If the above methods can't be solved, I suggest you go to Apple Mobile's after-sales service center for testing and maintenance.
