What's going on when the screen is locked and the internet is disconnected?

Recently, many users have reported that the network connection automatically disconnects after the phone locks the screen, especially when using Wi-Fi or mobile data. This phenomenon not only affects the normal operation of background applications (such as music playback, file downloads, etc.), but may also cause users to question mobile phone settings or operator services. This article will combine the hot discussions on the entire network in the past 10 days to analyze possible causes and provide solutions.

1. Statistics on hot topics

2. Analysis of common causes

1.System power saving strategy: Most mobile phones will actively turn off background network activities after locking the screen to extend battery life, especially when the "Super Power Saving" mode is turned on.

2.Wi-Fi sleep settings: There is a "Keep Wi-Fi connection during sleep" option in the Android system, which may be set to off by default.

3.Carrier restrictions: Some 4G/5G packages will lower the network priority when no active operation is detected, resulting in actual disconnection.

3. Comparison of solutions

4. In-depth technical analysis

From a system level, modern operating systems useDoze mode(Android) orlow power state(iOS) Manage background activity. When the device is stationary and the screen is turned off, the system processes network requests in batches, causing the user to perceive a "disconnection". Actual measured data shows:

6. Professional advice

1. Priority inspectionBattery optimizationlist, and set applications that require continuous Internet access to "Not Optimized".

2. Operator users can try to send「KTVOLTE」Go to 10086 (China Mobile) to enable the VoLTE high-definition calling function. Some models can improve network retention capabilities.

3. Developers can refer to the latest version of Android background restrictions document to optimize the application wake-up strategy.

This problem involves factors at multiple levels including hardware, system, and operator. It is recommended that users choose an adjustment solution based on specific usage scenarios. If it persists, it may be a baseband hardware failure, and you need to contact official after-sales testing.
