How do I cancel the slogan similar to this that always appears when making calls on my Apple phone?

When making a call on an Apple mobile phone, there is always a slogan like this that cannot be cancelled:

This item cannot be cancelled. This is mobile color printing and has nothing to do with the mobile phone. Mobile color printing is a value-added service that delivers additional information during a user's call. During the call between the calling and called users, the system automatically pushes the color printed information (mood, jokes, business information, etc.) preset by the user to the other party's mobile phone, so that the other user can see the color printed information after the call ends. To achieve the purpose of showing personality, sharing mood, and conveying business information.

What should I do if the battery of my iPhone is not durable?

Apple mobile phone batteries are not durable and need to be optimized:

1. Pay attention to the environment where the battery is placed, avoid contact with metal materials, and place it in a comfortable and dry environment.

2. Turn off WiFi, GPS and other services in a timely manner. Most mobile phones support WiFi wireless network services and GPS global positioning services. Although we can enjoy free Internet services through WiFi, if Please turn it off when you don't need it, because the data exchange after we connect to WiFi will also consume a lot of power.

3. Carry charger and data cable with you.

4. Carry mobile power and spare batteries with you.

5. Optimize APP with the help of battery.
