How To Fix Sony WF-1000xm4 Earbuds That are Not Charging (STEPS)

Why Are My Sony WF-1000xm4 Earbuds Not Charging?

The reason Sony WF-1000xm4 earbuds are not charging is that the charging port is dirty, the power source is on standby mode, the battery is faulty, or the software needs updating. 

                                                                            

Possible Causes OfSony WF-1000xm4 Earbuds Not Charging

• The USB Type-C cable is not connected to the headset
• The computer is in hibernation or standby mode
• The battery is faulty 
• The earbuds software needs an update
• The charging port is dirty

 

The USB Type-C Cable Is Not Connected To The Headset

Sony WF-1000xm4 earbuds come with a USB Type-C cable. If the device is connected to some other cable for charging, it may not end up getting charged. Hence, you should always use the accessories with the device for charging. 

 

The Computer Is In Hibernation Or Standby Mode

It is common for users to connect the charging cable to one of the slots on their laptops/computers. However, if the computer is on standby mode, the power flow will be disrupted, so your earbuds won’t end up getting charged. If their battery is low, they will continue to work on borrowed power, but they won’t be fully charged.

 

The Battery Is Faulty 

Worn-out batteries or a battery that has completed its full life will pose some problems when you try to charge it. This is a hardware-related issue and doesn’t get fixed easily. In this case, you will have to get the batteries changed at the earliest by a professional.

 

The Earbuds Software Needs An Update

Earbuds’ software must remain updated at all times. Sony sends constant reminders to users to remind them of software updates. However, people still tend to forget. If there is no apparent reason for your earbuds not charging, you should check if you’ve missed a software update. 

 

The Charging Port Is Dirty

A charging port remains exposed to dirt and dust, accumulating over time and preventing your earbuds from getting charged.
