You can try several solutions to fix the charging issues. Here are some common solutions you should try before throwing in the garbage-

1. Place Your Earbuds Correctly

The most common reason why wireless earbuds won’t charge is incorrect placement.

We often place the earbuds without paying attention. Usually, the magnets align the earbuds and align with the charging sensors.

But, sometimes, magnetic force fails, and one or both earbuds don’t connect with charging pins.

As a result, the earbuds won’t charge even though the case is fully charged.

The first thing you should do is- remove both earbuds and place them back in the case. They will start charging.

2. Charge Your Case

Although Sony WF-1000XM4 gives a decent battery life, but it discharges after 20 to 22 hours of use.

The battery is already low if you haven’t charged your case since yesterday or used it after a week.

If you put your earbuds in the case, the charging case doesn’t have enough power to charge them.

It is better to place both earbuds in the case and connect them to a charger. Leave it for 30 minutes and check whether your earbuds are charged.

If they are still not charged, it means the problem is somewhere else. Try the next solution.

3. Clean the Contacts

Although the Sony WF-1000XM4 case supports wireless charging, the earbuds don’t charge wirelessly.

You must have noticed metal contacts on your earbuds and inside the case. These metal contacts act as electric mediums and charge your earbuds.

Over time, your charging case attracts dust and moisture and covers the metal contacts.

Now, whenever you place your earbuds in the case, the dust layer acts as an insulator and won’t pass the current.

As a result, your earbuds won’t charge even if your case is fully charged or connected to the charger.

4. Update the Firmware

From the apps menu, select Sony WF-1000XM4 and check for firmware updates.
