Why does the car Bluetooth only play for 20 seconds and then go silent?

Introduction to the reasons why the car Bluetooth only plays for 20 seconds and then goes silent: In most cases, this situation occurs due to unstable Bluetooth performance. If this happens immediately when the phone connects to the car, it is likely due to incompatibility between the phone's and the car's Bluetooth. If this has not happened before, a detailed analysis of the problem is required. Here are the reasons why the car Bluetooth plays for a while and then goes silent: 1. Too many connection records: Bluetooth is easily interfered with. If there are too many Bluetooth devices connected to the phone, the signal may be affected, causing the Bluetooth to switch connections between multiple devices, leading to connection interruptions. 2. Car electronic devices: If too many electrical devices are turned on in the car, it can affect the signal reception of the car Bluetooth. In this case, try turning off some electrical devices. 3. Bluetooth lag: Unstable Bluetooth performance can cause lag, resulting in the song playing but the speakers having no sound. 4. Interference: If the phone's WiFi is always on, it will continuously search for nearby wireless networks, which in some areas can interfere with Bluetooth, causing intermittent connections. In severe cases, the system may cut off the media audio for safety reasons.
It's really annoying when Bluetooth suddenly disconnects while driving. I feel the issue lies with the Bluetooth connection. For example, if the phone is too far from the car's head unit or the signal is interfered with, nearby Wi-Fi routers or other electronic devices at home could cause trouble. I've tried restarting both the phone and the car's system, which sometimes works for a few minutes before disconnecting again. It's necessary to check if the Bluetooth settings are outdated and incompatible. On the other hand, low battery levels in the car can also affect it, especially when charging under heavy load, so ensuring stable power supply is crucial. Aging Bluetooth modules are also common; after a few years, car electronics inevitably develop issues. Lastly, bugs in phone apps shouldn't be overlooked—music players being closed in the background or power-saving modes activating can mistakenly interrupt the audio stream.
As a car enthusiast, when encountering Bluetooth audio issues, my first thought goes to phone settings. For instance, if Bluetooth permissions or music app permissions aren't fully enabled on an iPhone, playback might get forcibly suspended by the system after a while. I've also experienced situations where power-saving mode throttled Bluetooth performance, causing 20-second audio dropouts. Firmware updates are crucial - older versions often have bugs affecting connectivity, so checking for the latest update in phone settings is essential. Additionally, too many paired devices in the car's Bluetooth memory can cause conflicts; clearing unnecessary connections helped alleviate my problem. High system load during vehicle startup might also lead to insufficient resources - playing audio at idle tends to be more stable. Apps like Spotify sometimes malfunction by closing background tasks, requiring manual app locking or restarting.
