Most of the xm4 units are facing battery issue by now, though most of them are replaced already but as sony is launching their new xm5 soon and most of the potential customers are those who already having issue with xm4,i doubt they gonna buy it again...sony should have come up with solution, they should do something for the huge number of customers who are( 1.fan of sound quality 2.high tier spenders 3.loyal sony fan).... currently people are completely freaking out....

Sony should include another setting in the Sony Headphones Connect app that allows the earbuds to be charged to 80% max to greatly increase the total number of times the WF-1000XM4's batteries can be charged and to slow down battery degradation.

[@thisiscuvo]

if that's the case I suggest another one which only allow slow charging since fast charging also make the batteries degrade faster.

Started noticing signifcant shorter battery life with new update 2.0 past few days even with multipoint turned off. Also having same problem when connected to 2 devices with youtube pausing every now and then, which was why I stopped using multipoint. Hope Sony fixes these issues soon, don't want a repeat of what happened with 1.4.2 since my warranty already expired this year.

I am not using multipoint, i updated from 1.4.2 with no issues to 2.0.0 and battery is lasting a lot less.

[@DavidEsp1]

After the update, I also re-tweaked my custom EQ settings - to emphasize bass even more than before (a massive "V" !). So presumably that affects drain? Further, I guess drain depends not only on the buds' level-setting but also on the spectral content and degree of dynamic range compression in the music (or whatever) itself.

[@WaeForwards]

I gave up on my XM4 earbuds already. Now using version 2.0 and the battery still drains very fast, it lasts around 20 min only. Looks like I will need to go to one of the Sony Center and get the battery replaced.

I updated both of them to the latest firmware version 2.0.0 and immediately afterwards the battery in the right earbud on both units will go from 100% to 0% in 1 hour and 30 minutes. I am out of warranty on both units, but Sony said they will replace them for free as long as my WF-1000XM4s do not show any signs of physical damage. I live in the UK and purchased both my WF-1000XM4s from Amazon.

Like ive contacted sony and they are wanting me to send them back however its out of warranty which means it can cost about 100 quid just to fix them.

Alright, putting out my story out there in case someone can make sense of it. Since recently, I hadn't seen any battery problem - iirc, until a few weeks after a software update. I was surprised one day, I plopped in my right earphone and it felt hot - pulled it back, set it back in the case, and got it out 5 min later with a thermal camera. A hotspot below the charging pads was at 45-50°. This heating only happened once, but since then my right earbud only lasts about 20-30 minutes, and the left one maybe twice as long... Idk if Sony could have messed something up with the battery charging in their firmware update, I ordered replacement batteries and will attempt self repair, hoping that'll fix the problem. (Disclaimer : could also be natural battery degradation which caused this heating problem in the first place, since I often use a single earphone while cycling and it's always the right one given It's my left ear facing traffic - so my right earbud definitely saw the most use and rapid temperature changes...)

[@angrychivafan]

So how do you get them replaced?

[@Luhmixer]

I bought a new 1000xm4 3 days ago and immediately installed the new firmware. I noticed that when I put the headphones in the charging case and clamp the contact lock installed on delivery between the headphones and the charging case so that the headphones are not charged and then switch them off by command in the app, so that they are virtually in the delivery state, they then strongly self-discharge with 35 percent in a few hours. If, on the other hand, you put them in the charging case normally, even though both headphones have just been fully charged, the case then discharges in order to permanently recharge the headphones, which discharge themselves even though they are actually switched off. Of course, this quickly drains the batteries if they are permanently discharged and simultaneously charged to 100 per cent again. Something is very wrong here

I want to add.... their multi-point implementation is DREADFUL. I turned it off two weeks ago. I had my phone and ipad both paired, and would often leave my ipad in another room while listening to my phone. When you're at the wrong distance, it would connect and disconnect and reconnect and disconnect and play sounds each time as I moved my head around and it went back and forth.

If multipoint connection is not your main concern, I suggest against updating. Before updating to 2.0.0, my unit's battery can easily last 12 hours, sometimes even 13. Now, after updating to 2.0.0, it can hardly manage 8 hours. Both buds' battery drain at about the same rate. For context, I tested it with the following settings (which I use almost all the time), both before and after updating the firmware: - Multipoint: Off - DSEE Extreme: Off - ANC: Off - Adaptive sound control: Off - Priority on: Stable connection - Codec: SBC - Volume level: 20% In short: Turn everything off. To summarize, firmware 2.0.0 will f*ck up your battery badly. Of course, your mileage may vary.

[@dac4770]

​@@Spadenace If your battery is completely drained within an hour, it sounds more like the previous battery draining problem. In my case, it was pretty severe.

I suggest you take it to a Sony service center to have a check.

[@ptrsnkev]

Yeah they don't care about that, they just need both buds with the charging case, don't need the charging cable either, once they get it in about a week or less they'll either fix the issue or send you a brand new pair, that's how I got my new ones

[@jsomething2]

my year old ones are currently getting replaced by Sony for left dieing quicky while the right still had 60% left. I hope the new one is better. I hardly even used the left on, I mostly use the right one.

[@claytonparker1371]

my earbuds do not work at the same time. I can only use on at a time and have reset them so many times. Sony knows there is a problem but has no resolution

[@athaberyl3587]

Can i replace my product without receipt? I lost my receipt

[@jeremyngpiano]

Not sure if it's the result of the latest 2.0.1 update, but recently I'm having my left bud die in less than 1 hour. Had enough of these wireless gadgets.

[@Melgarockk]

I have the same issue, it is drained very fast in R, what is the solution for this?

[@alif19995]

My pair us about 1 year + and the battery is really bad. dies after less than 15 minutes. Still possible to get replaced by sony?

[@SwavyPremium]

I realized a couple months back that my xm4 earbuds loose battery really fast over time which is unfortunate. They last me at most 30 minutes and as little as 5 minutes so it’s at a point where I can’t even use them which sucks cuz they were like 300$😭

[@ashokjadhav9904]

If they are still under warranty ( less than a year since your purchase), please take them to Sony service. They'll replace both the buds. Charging case will be the same. If your buds are outta warranty, then there's no point in replacement. They cost almost as much as new set. I had same experience with my set. It was under warranty ( only a few days were left for completion of a year). They xchanged them with the new ones. Now they're working well BTW I have avoided the upgrade to new firmware.

[@SwavyPremium]

@@ashokjadhav9904 thank u but sadly I got them the day after release so it’s nearly 2 years since I purchased /:

[@ashokjadhav9904]

@@SwavyPremium oh I see. Then it's really sad These batteries in the buds are so small, they can't be replaced. The entire bud must be replaced. Here in India, each bud costs like Rs 7000. At that rate, both the buds are 14000 Rs. Whereas you can buy new set for 16000 or 17000 Rs ( depending on the store). So there's no point in replacement of buds after paying money. I suggest that if you are buying new ones, then don't buy WF 1000 XM4. Buy the other new model. It also has noise cancelling feature

[@SwavyPremium]

@@ashokjadhav9904 I think I’ll probably buy a different brand of earbuds that are cheaper because I find myself preferring headphones now anyways. However, thank u for the information I appreciate it

To fix drainage problem. I UPDATED 1.6.1 then I turned off everything including updates. Battery life good. I am happy.

How do i know the new new batch .... Been seeing these going for a good price and i would want to get a pair

Just received mine. WF-1000XM4 7378245 FCC ID AK8YY2948 Model YY2948....just in case there's a batch number that affects certain battery.... I'm reading more and more about the firmware updates with battery issue. Would you suggest, not to update the firmware unless there is noticeable issues? thanks

[@leonb9260]

Is the battery test done with normal use? or did you only play music and didn't touch it till the battery was drained?

[@aaronloudnwireless]

Yup only played music on loop till drained

My XM4 was still working perfectly fine after like two years of using them. Late to the party I updated the firmware in march 2024 and now the left earbud drains the battery in 15 minutes! And there´s no fix for it? This is so stupid. Sony made my earbuds useless with a firmware update!

[@orepoutanes]

36 days now have passed and my XM4's are STILL in the service center waiting for REPLACEMENT!! Gotta LOVE it! NEVER sony AGAIN!

[@DeneF]

Reminds me Aaron. When i clicked your discord link from your page bio it was a dead link (about 3 weeks ago). Thanks.

[@aaronloudnwireless]

Oh yes i was notified about that. The one on this video is a new one. Let me know if it doesn’t work!

[@GouAndSotsuWereMistakes]

This is still an issue, new update wont let me charge my earbuds anymore due to overheating. It sucks, i really like these earbuds.

[@daniellr2232]

Hello guys, I hope y'all be fine. I brought on eBay a earbud replacement (Right) for Sony wf-1000xm4 and came with the 2.6 firmware version, mine have 4.5 firmware version. And now when I'm trying to update, failed in 51% always then I have to start it again 2% to 51% and again....... I need help

[@AbrahamZX1]

I had read before that if both buds are not on the same firmware, you cannot pair them or update them.

[@DeneF]

I thought my battery was running less but I run two pairs and so battery length has never been a big focus point for me. There have been other strange changes though. Lol

[@aaronloudnwireless]

Strange changes?

[@DeneF]

@@aaronloudnwireless Yeah. I mentioned on one of your other WFXM4 video's. The right bud of one pair now remains showing 100% always and thus never gives me the battery audio warning at 20% any longer. Also, when that right bud runs out of power my left bud now cuts off and will not connect any longer. This never happened before, if one bud died the other just carried on. With this right bud dying at about 23% quicker than the left is basically means I have also lost 23% power from my left bud due to as mentioned above that it will not stay connected in its own since the update. Thanks Aaron

I thought i was the only one. My buds have been dying out fast for the last few Months. I have accidental plan with best buy for them i feel like i need to change them out

I thought mine were defective. Connecting to 2 devices has halved there battery life..

It definitely does my right ear runs out now while the left still has 25 to 30% left and the overall battery life is about 1 1/2 2 hours less.

[@RedcubeX24]

I got mine 26 months ago so warranty is over by two months and my left bud suddenly started going empty in 30-45 minutes. Sony germany is refusing to do anything about it.

[@pauledwards5573]

Ok so what I have done is I have not launched the Sony headphones app and I've turned off all the excess bells and whistles and so far the left and right batteries are pretty much equal. They've been in my ears for about an hour now.

[@Veiame]

How do I know if I have old earbuds

[@dresdner_stinkstiefel8603]

I think since the update to multipoint, my left earbud doesn't charge to 100% anymore and lost battery capacity really really fast. So my right earbud has about 80% and the left one ist completely empty... I think sony does it, because the want us to buy the new xm5. It makes me really sad, because the sound is absolutely crazy but the software destroyed the earbuds. Also the software/ the app is overloaded. There are so many options i will never use. Just make it clean and simple.
