Hi guys, my WF1000XM4 is draining battery fast, is it hinting that the battery need to be replaced? I have them for about 17 months in use.
Anyone done the battery replacement in Sony before? Wondering how much is the cost and will it damage the IP rating.
Thanks.

Have u got the batteries replaced??? I’m having the same problem

No, chat with Sony they do not provide battery replacement service in Malaysia...however if you have sufficient tools and skills, may try to DIY as there is tutorial available on Youtube.

It’s whether your brave enough to pry it open. Need to find suitable battery to exchange. Have you tried it on your xm4?

having same issue as TS, so no more warranty and they cant repair it for you?

No I did not, I will just use till the battery fully die then replace a new TWS, instead of pry open it and damage it now, haha

Based on my online chat with SONY, it seems they don't provide battery replacement service but they do sell the TWS in loose in case you want to replace it . But I will just wait till newer version release and change to new one, since I know this brand new battery condition can only last me for 1 year plus...

The battery drain issue on the right earbuds is a global known issue. Many countries are giving replacement (both earbuds , not just battery replacement) even if it's out of warranty. It's not just US and Europe but Philippines as well.
I got mine replaced 2 weeks ago and the service center do acknowledge this issue. However, my unit was not out of warranty so I'm not sure if our country honour the global procedure. I would say give it a try and tell the service center front desk ppl about this. They may have special memo for this rare issue and insist then to check with their higher management for it. This is a known issue globally and can easily Google for evidence.

i saw careousell got battery replacement service for XM4..cost Rm250 for both..not sure can nego or not

It's a known issue worldwide. Though I'm not sure if Sony Malaysia acknowledge it
Other countries allows for exchange even for out of warranty units

Dont think Sony Malaysia so generous...but lucky enough changing the battery yourself wont really need too technical.. I just done my XM3 battery change myself today...

I have a written guide on XM4 battery replacement process here: https://www.head-fi.org/threads/clieoss-ran...2/post-17462139

Also, you can find quite a few youtube video on the subject.

Update*** For those who facing power draining issue, please get your unit check at Sony Service Center as Sony is offering FOC replacement to those affected unit, they will check your serial number and also your unit first before proceed to replace the earbuds, if the problem is your charging case then no FOC replacement will be offered. THIS APPLY TO OUT OF WARRANTY UNIT TOO!

sometimes get cheaper one around 200 good enough :X

Wow seriously? I also have this issue, guess it's time to have a visit.

Ok today my little sister went to Sony Center Lowyat to get my out of warranty WFXM4 replaced. The Lowyat spokesperson said they will replace it for free with a new one no problem. But they advice to go to Lalaport or The Curve to get it replaced, if you want to get it faster.

may i know is change new set or change battery ? my wf-1000xm4 right side only can last around 30 minit. out of warranty 2 month also can repair ??

They will change the buds to a new one both pairs.. but the charging case they will still use the old one. I heard the charging case they will fix and tune for it to work nicely with the new buds, that's all. So new pair of buds, but old charging case.

Yes out of warranty also can claim.. mine has been out of warranty for 3-4 months now, still can get it replaced. This is international now I think, previously only heard they replace it in the US.

thanks for your good info , may i know only the curve and lalaport can replace with new unit ?
