Just for anyone with sony wf 1000 xm4 to take a reference. I am a HongKonger and own a pair of sony wf1000xm4 which is out of warranty.
Previously, I experienced the same uneven battery draining issue. My right earbud can go from 100% to 0% in less than 20 mins while my left earbud still have over 80%. This severely affects my user experience.
I went to the sony local store and they replaced the earbuds (but not the case) for me after 1 week for free. For anyone having the same issue, I highly recommend that you go for replacement as soon as possible.
However, after replacement/software update to 2.0.0, I feel that the ANC is worse than before. This is something that I think we all should be aware of, maybe sony is trying to make their xm4 worse so that they can get more sells with their comijg xm5? Idk.
Thanks for your videos man, it really helps us a lot.

I hope no one is blaming you guys. You were just informing us of the new updates. It's great that we can get refunds for their mistake.

[emiliobibie]

I'm so glad that you finally exposed this major issue ! I'm rocking my Bose QC2 now ever since this cursed xm4 stopped working last year. Well done, DHRME!

Great to know that you guys will acknowledge and fairly test other complaints and comments. Most companies now will just let loose the lawyers and tell you that you are the problem and you're using their precious product incorrectly. I now value your opinions more and put more weighted trust in them compared to other reviewers, keep up the good work. Unfortunately we live in a time where companies believe it is ok to force a software "Update" which will degrade the life and functionality of the product that you purchased so that they can sell you a "New" release product.

I had this issue. Had to fight with Sony to get my set replaced because they were out of warranty by a few months but they eventually agreed it was their fault. Sold the replacement set as soon as it came in and won't be buying anymore Sony earbuds. They could have gotten out infront of this but just didn't bother.

I appreciate you fellas addressing this problem, it hasn't gotten nearly enough attention.

Battery degradation doesn't make any sense as you wouldn't expect one earbud to be substantially different than another.

[eskimofoi]

Can confirm. With the 1.4.2 Update it killed my batteries. I first noticed the case extremely hot and a red light on the case. Then my left earbud would never fully charge. The left earbud would die extremely fast. I put them in the drawer and haven't used them since.

Recently the new update released so I had hope it would be fixed. Unfortunately even with the new update my left earbud does not fully charge and still drains extremely fast. Also the case does not fully charge or it discharges when not being used.

These now sit in my drawer unused. My 1More EVOs are my daily driver.

The xm4s came out about 2-3 years ago, it may be that the batteries are finished in the buds. I have an issue where my earbuds say they are charged but they last only a few minutes. I hate the way the fit so I kinda gave up on them and didn’t bother following up with Sony.

[Olejo]

I experiencing the same problem. 20 minutes with ANC and left bud battery depletes from 100% to 60% and shutdowns while right bud still at 96%.

[mattparsons]

This highlights a larger problem in the TWS space - that they're all basically throwaway electronics. Which is wasteful and kind of makes investing in higher end sets a difficult proposition unless one wants to do it every 2 years or so. Contrast this with spending the same amount of money on headphones/IEM's and provided you treat them properly they'll last 10x as long. This obviously benefits MFG's as it puts everyone in this 2-3 year replacement cycle hamster wheel.

Audio gear has always been one of those things you can often buy once and enjoy for 10-20+ years; but we've married them to technology that dies in 2-3. This seems like planned obsolescence. The hell with lossless bluetooth, the next big thing in the TWS space should be properly maintainable gear.

Mine had a 19% difference but the 2.0 update means one buds status reads 100% always. When it dies my other bud still reads around 20% but now it cuts off too unlike before when it would stay working solo until it ran out of battery. I can't even reconnect the bud that still reads 20% on its own any more. Crazy crap! My second pair are working fine after the 2.0 update.

[hedgeymcgee]

Great content, glad you addressed. I give Sony credit though. I contacted them, and after some customer service trying to fix, they said return and we’ll send you new ones. It took about 10 days, but they sent me a new pair! And I’m talking about my pair was bought June ‘21 and they still replaced. Big props to Sony. Big props for your video addressing this issue.

[nandhagopal]

I have the same battery issues in my xm4 earbuds.
It was given as a present for my birthday, after some Google searches I found that changing the battery is good.
So I ordered a pair and changed both left and right earbud batteries, now it's working good.
The model number of the battery is Z55H ( 3.8v, 0.29Wh).
I ordered from Lazada.

Sony is not ready to take these buds back and yes the problem still persist - Thank you for bringing it up to the world ... Though these were one of the favorite's but unfortunately cannot use them anymore as battery drains completely in just 20 mins. Sadly, nothing can be done as the warranty period is over.

[shshankking]

I had the issue, luckily I was 1month away before warranty expire. My issue was uneven battery drain.
Got replacement and working fine on latest firmware.

[uabir]

My right bud drained quickly. At the end when it died, the left one had 28% juice left.
IMMEDIATELY exchanged it at best buy and it had the same issue. Then I called Sony and they agreed to replace it. But the replacement would take some time so I said to them that I'll take the replacement a few months down the line. After 6 ish months the batteries were kinda worn out and the issue was a lot bigger and I had to take the replacement. The new ones are a bit better balanced but the problem is still there

[Apeeksiht]

What i have read on reddit is that people who bought before 2022 had suffered the longest time with that firmware. I bought it 6 months ago i don't remember being on 1.4.2 update but as of now i don't see the battery drain.

[rizwan]

Excellent video 📹 thank you. The issue with a microphone during calls 📞 has not been fixed..any updates regarding that issue?

[jbpierce]

I bought these back in 2022 and since late last year 2023, I too have been noticing battery problems with mine. The right bud also drains quicker than the the left one. I really find this a shame because I really like using my XM4's.😔
