Even if you don't use your phone at night, it continuously transmits your data. This includes data that can reveal sensitive information like your location.

If you don't switch off your smartphone while you sleep, you need to pay attention. While you're sleeping and your phone is on standby, it continuously sends and receives data. Some of this data is necessary to keep your phone updated and provide you with the latest notifications as soon as you pick it up, but some unnecessary data is also being transferred.

What kind of data transfer is concerning?

Smartphones transmit data throughout the day. This includes data that is used for user tracking and advertising. Experts say that this personal data should not be transferred without the user's consent. This data includes your location, device information, usage patterns, and other information. Even if you're not using your phone at night, this data is constantly being shared. This leads to user profiling, which is then used for targeted advertising. Last year, several large companies were accused of spying on Android users. There have also been cases where users saw advertisements related to products they had discussed the previous day.

How to avoid this?

To avoid background data sharing, you should pay attention to the permissions granted to your installed apps. Some apps take unnecessary permissions and then continuously transmit data. To prevent this, review the apps that have permission to access your microphone, camera, and tracking data. If you're not using them, uninstall apps that remain constantly active in the background. Similarly, you can disable background app refresh on both Android and iPhone.
