Apple mobile phone tips

1. Buying an iPhone6s or iPhone6s Plus is no longer a gift of a data cable adapter, but a gift of the Bank of China version before that. Will you feel sorry for the newly bought little apple?

2. The iPhone boot screen of the black panel is black, and the iPhone boot screen of the white panel is white.

4. Japanese and Korean versions can't be muted. In order to prevent candid shots, you won't die if you don't die. Why do you want to try it? The most vivid interpretation.

5.Apple Pay can be used without Internet connection. I don't know if Little Apple has paid with Apple Pay. Fried chicken is convenient.

6.6. The iPhone's call record can only keep the latest 100, so Apple should be diligent and store important numbers in time.

7. Before the iPhone6, there seemed to be two speakers on the bottom of the phone. In fact, one of them is a microphone, so only one can ring, including iPhone SE.

8. The flash and HDR cannot be turned on at the same time when taking pictures.

9.9. The SMS function of iPhone sends video and audio information, which will be automatically destroyed within two minutes. At the same time, the little apple can also set-set the automatic destruction time of such information in the information.

10. Many small apples may not know that your iPhone has been silently recording your destination information in the background. We can see that there is a "frequented places" option in Settings-Privacy-Location Services-System Services, and the data of places frequented by several small apples will be displayed at the bottom of this menu.

11.iphone6s/iphone6s plus can directly call out siri, whereas previous versions need to call out siri when plugged in.

You can set it in Settings-General siri.

12. Want to know which applications in your mobile phone are big power consumers? No problem! You just need to open the Settings-General-Use-Battery interface, which will provide you with detailed data on the power consumption of each application.

13. After resetting the time, iPhone can't make calls without synchronizing the time, even 1 12 can't make calls.

14. If you buy a second-hand iPhone, I'll tell you the safest way. Connect the mobile phone to the computer and brush it. After the machine is brushed, what model iTunes shows can't be wrong.

15. The fingerprint module of iPhone matches with baseband CPU (small CPU), main CPU and hard disk. If there is a problem with the above one, replace it all. However, there are some special cases, such as hard disk, whose data can be rewritten (this is the principle of iPhone expansion), so it is generally possible to replace the hard disk separately.
