I have had Sony WH-1000XM4 with me for a while and never faced any issues. However, a few days back, when I picked up my headphone and plugged the charger, it was no longer charging. Its red light was not flashing.
But with patience, I researched online to figure out why my headset was not charging and how I could fix this problem. Thankfully, after basic troubleshooting, my headset charging problem was fixed.
So if you are facing the same problem, don’t worry. I will explain how you can also fix your Sony WH-1000XM4 charging problem.
How to Fix Sony WH-1000XM4 Not Charging
The first thing I tried was to press and hold the power button and plug the charger into the headset; after a few seconds, the headset started charging.
So you should also try this; if the problem persists, try the fixes below.
- Reset your Sony WH-1000XM4. (Method is described below)
- Try another charging cable maybe your current cable is not working or make sure it is firmly plugged.
- Maybe the charging port is get wet or moisture, therefore dry it by blowing in with the blower.
- Sometimes headset is over-discharged and take more time to show the LED light which indicate that headset is charging.
- Make sure when you are charging headset the outside temperature is between 5 degrees to 35 degrees out of this range headset won’t charge.
- If you are charging your Sony WH-1000XM4 with the PC then make sure it is not in stand by mode.
- If the firmware is outdated then update it sometimes it create glitches in the headset.
1. Reset Headset
Sometimes headphone doesn’t charge because of minor software glitches.
So to remove software glitches, you should reset your headset because resetting will clear the glitches and increase your headset’s performance.
Follow the below steps to reset your Sony WH-1000XM4.
- Press and hold Power and Custom buttons simultaneously while the headset is charging.
- Your headphone will be reset.
After performing a reset, check whether or not your headset is charging if it is not charging, then perform a factory reset.
You can perform a factory reset by following the below steps.
- Turn off the headset and make sure it is not plugged in.
- Press and hold the power button and custom button simultaneously for more than 7 seconds.
- The headset LED indicator will flash blue four times.
- Your headset will be reset
2. Charging Cable
Your headset will not charge if you use a third-party charging cable because these are incompatible with the Sony headphones. So always use the original charging cable that is given with the headphones.
The second thing you should ensure is that the charging cable is firmly connected to both ends. Because sometimes, we don’t properly plug the charging cable, which creates the charging problem.
3. Charging Port Got Moisture
In most cases, the headset doesn’t charge because its charging port gets moisture and doesn’t allow the electricity to pass through.
Mostly the charging port will get moisture if you use your headset near the sink or the liquid container or if you are in rain or snow are high humidity. Also, if you touch your headset with wet hands.
So remember, if you have done one of these things with your headset recently, it means the charging port gets moisture, which is why your headset is not charging.
So you should dry the charging port of your headset with the help of a blower.
4. Headset is over-discharged
If your headset has not been charged for long, it will take more time to charge. Usually, if you will not charge your headset within six months, its battery will be over-discharged and take more time to recover.
It will start working fine after charging and discharging a few times.
Usually, Sony headphones will be charged within 2 hours; however, it can take longer to charge if over-discharged.
So I recommend you charge your headset for at least three to four hours.
5. Temperature Exceeds
Sony WH-1000XM4 will not charge if the outside temperature is below minus 35 degrees are above 5 degrees because this headset has a lithium-ion battery that stops charging outside of this temperature range.
When the temperature is not suitable for the headset, its LED indicator will flash red. So, in this case, you must wait until the temperature is ideal for the headset.
However, f your headset is not charging within the normal temperature range; you should contact your nearest Sony dealer.
6. Computer in Standby Mode
If you have plugged your handset into the computer and your computer is in standby mode, then headset will not charge. Because in standby mode computers don’t supply electricity.
So if you are charging your headset with the computer, disable the standby mode of your computer.
Follow the below steps to disable the standby mode of your computer.
- First, go to the settings of your PC.
- Go to system and power and sleep
- Select the dropdown menu under sleep and choose never.
7. Replace Battery
If the battery usage of your headset significantly decreases, then you need to replace its battery.
If your headset charging problem persists after trying all of the solutions, then maybe it has a battery problem, and you need to replace it.
When does the battery degrade or damage?
You should not expose your headset to direct sunlight, moisture, heat, dust, and electric shock. Because in these cases, your headset battery can easily damage or degrade. Due to this, you can run into the headset charging problem.
8. Update Firmware
Sometimes outdated firmware can create issues in your headset, and maybe that’s why your headset is not charging, so you should update its firmware.
Follow The below steps to update your headset firmware.
- Download and install the Sony Headphones Connect app.
- Then connect your headphones with the Sony app.
- Tap three dots in the upper right corner.
- Then select your Sony WH-1000XM4 headset.
- Confirm the firmware version and update it.
9. Contact Sony Support
If neither fix works for you, you should contact the Sony support team.
First, they will tell you the basic troubleshooting we discussed above, then ask for your headset-specific model and suggest some steps.
However, I will highly recommend you return your headset if it is under warranty.
