What if Apple 12 mobile phone can't receive SMS?

1. Check whether the mailbox is full. If it is full, please delete some information;

2. If you still can't get it after deleting it, I suggest you change the machine or card to see if it is caused by hardware;

3. Check whether it is intercepted by mobile phone interception software;

4. Check whether the cell phone signal is normal and try to test whether it can be received in other places.

5. Is the mobile phone in arrears? If you can't receive the text message, consider whether the operator sends a text message to remind you to pay the phone bill.

Tips to extend the life of iPhone battery;

1. Develop a good habit of charging.

When Apple's mobile phone prompts that the battery is low, charge it in time to avoid automatic shutdown due to low battery. If the battery efficiency is less than 80%, please try to replace the battery.

2. Turn on optimized charging

This function can intelligently learn and judge the user's usage and charging habits, so that the charging process is more balanced, thus slowing down the aging of the battery and improving the battery life to a certain extent.

How to View: The function of "Optimizing Battery Charging" can be viewed in Settings-Battery-Battery Health ~

3. The background application refresh is prohibited.

Applications use battery life when running in the background. You can see how long the application has been running in the background. If the application runs out of power when not in use, you can disable background application refresh to prevent it from running in the background. If the application consumes too much power, we can also choose to uninstall it!

The "low battery mode" function can make the phone save more power. When the low battery mode is enabled, your screen will be slightly dimmed, limiting background processes, slightly slowing down the processor, or reducing the energy required by the device during normal use.

Push application notifications, email reading notifications, etc. It will shorten the battery life, so it's best to turn it off if you want to make the iPhone battery life longer. You can edit each application and turn off notifications in Settings.
