1. It's annoying to hear a text message twice!
I believe many babies have encountered the troubles of repeated text message reminders. In fact, this is the default anti-leakage function of the iPhone. If you do not like it, you can choose "set"> "notification"> "information" to set "repeated reminders" to "never ", the text message will only sound.
2. Who sold you for advertising tracking?
Do babies feel that the ads recommended by the iPhone are particularly targeted? When I arrived at a place on May Day, I received various strange hotel advertisements. In fact, this is the iPhone's advertising tracking function, which can display more targeted ads based on users' location, attention content, and usage habits. You can enable "restricted ad tracking" by "setting", "privacy", and "advertisement.
3. Send diagnostics and usage. I'm not ill!
The mobile phone automatically sends diagnostic and usage data every day to help Apple improve its products and services. However, this function collects all log files generated by crashes on your mobile phone, it also contains information such as geographical location. This function is useless in our daily use and wastes traffic. So, go to "Settings"> "privacy"> "diagnosis and usage", and turn it off!
4. Who is the Wi-Fi Assistant?
The Wi-Fi Assistant function added in iOS 9 automatically switches to the mobile network when the Wi-Fi is unstable, which makes many babies consume a lot of traffic without knowing it. We recommend that you go to "Settings"> "cellular mobile network" to pull down and close "wireless LAN assistant ".
5. Handoff is useless.
With the Handoff function, you can immediately use the iCloud account to continue the same operation on another device. However, 80% of babies cannot use it. You can disable it by setting -- general -- Handoff and recommended application.
6. Airdrop, which can be used as needed.
Airdrop is equivalent to a Bluetooth function that can only be used between iOS devices. If it is enabled all the time, the iPhone will automatically search for devices that can establish connections in the surrounding area and consume power. You can close it through the pull-up control center and open it again when necessary.
