Thanks! I bought the battery and some T9000 glue off of eBay coming to under $30. Was able to replace the battery in 30 minutes. The most difficult part was getting the case apart without marking up the plastic. I have spudgers, but ended up resorting to a sharp kitchen knife like another commenter suggested. I heated it with a hairdryer for about 30 seconds while rotating it around. It took a few tries but I was able to get open.

Great video, saved my buds. You can put the earbud in a water and heat proof plastic bag and then lower the bud and bag into boiling water for a couple minutes to soften the glue instead of a heat gun. Also the contact cleaner isn't needed to remove the battery glue, just use a razor and go really slow so you don't cut the center contact. After that the glue peeled off easily and I was able to use t9000 and just hold the contact down with finger pressure until it dried.

This video saved me so much money and frustration. Left earbud had that battery draining issue after the update and it got so bad that it died after 10 minutes playtime. Sony support was no help at all, only citing standard bullshit that it's normal that battery charge may differ between left and right (ya maybe for

Sony is fucking atrocious. In no world should it be acceptable for people to spend upwards of $300 for their earbuds to die so fast. I've been using mine for a little over 1 year, never had any issues and the battery on them were amazing, after the latest firmware updates however I've been facing the same issues as all you people. My leaft earbud will go from 100% to 20% in about 2 hours whereas my right earbud will still be at about 80%. I also noticed the left earbud overrheating when charging. This is genuinely unacceptable, and sadly by now the warranty has expired so I can't ask for any replacements. FUCK. SONY.

How do we extend the life of these batteries? I'm one of those who charges my iPhone and apple watch ultra to no more than 80-85%, to reduce the wear on the battery's. Unfortunately, I do not think you can set the charging time of the Sony ear buds.

With "LDAC/DSEE:Off/NC:On" settings applied the right bud shut off at 4h:57m with 3% still left in the left bud. With those settings Sony rates battery life at "max 5 hours".

@@NightWarJET 感謝回答，近期逛巴哈影音板一堆人的wf-1000xm4用久了都出現嚴重電池衰退問題，還沒過保的還可以去找sony客服處理，過保了就只能自己找看看有沒有坊間的維修站在修、或自己買電池來DIY維修。 雖然我的還沒出現這狀況，但保固期快過了，電池本來就是消耗品，假如想要延長耳機使用壽命總有一天會需要換，我很喜歡這耳機的聲音，假如哪天它的電池真的不行了也是會希望可以換電池繼續用。 另外充電盒的電池可能也同樣會有壽命問題，不過充電盒似乎比較沒那麼精密，拆裝難度應該會比較低。

You put in a 3.7v battery, it had a 3.85, the customer is going to come in 1 month to tell you that his battery died again

What glue did you use?

Use a three-purpose voltmeter to measure the voltage of the battery. If it is above 3.5 V, it should be able to start the machine. Check whether it is reversed. The metal contact piece cannot be touched. It needs to be adjusted.

@@nathanielangelojancamacam7584 ok i will try that

Used a hot air gun to open 3 ear buds. First tried 100C but not luck in opening. Tried 150C which was too hot and started melting the plastic. Found 125C was about right. From experience be careful as easy to pull apart too far and pull the ribbon cables out of their sockets. Anybody experience of alternative types of battery to fit as the originals are quite expensive.

I've opened a few more since last post and would suggest lower temperature around 115C. Does anybody know the reason why Bluetooth not pairing is beginning to happen with these buds?

@@paulbowditch7511 I could see the bud I repaired but no audio so I did the factory resets (hold touch pads for 10 secs, and open and close case 10x until blinking red light and then kept it closed until it showed green)

可唔可以搵你換電？😂 可以既話收費如何？
