Bro
Can you do same test with xm3
Let's see how much it run after 2 years
@@ahambhramasmii hi Bro. I have xm3. Since 2019. No issue till now brother
This problem just started for me. These earbuds are entirely too expensive to have such an issue.
Same with me, so now what do we send them in for replacement??? I am lost???
@@leonvainer7599 I got my batteries replaced myself, the case doesn't charge at all. The battery was like one time use then it wont charge and would flash red itself.
@@ryanrock07 I had similar problem to you as well. My issues were solved by cleaning contact pins in case with isopropyl alcohol and brush. In worst scenario, battery in charging case can be also replaced.
did anyone fix it .. cause sony is being cringe and fkn up the earphones after the update on purpose
@@leonvainer7599 hey I was gonna do the same, I called Sony and they are sending a brand new replacement they didint ask for a reciept or anything
I experienced a similar issue with my WF-1000XM4 headphones. Bought it more than a year ago, so the warranty ended 5 months ago. It was working fine, I was using it rarely, but suddenly it started overheating and the battery of the left one completely died. Now it works for ~5 minutes. After contacting Sony support they are very sorry and can only suggest contacting the service center for diagnosing and repairing it at my expense. After calling the service center they said it was not feasible to repair it because repair means just buying a new replacement for a broken headphone, which cost half of the new one.
Look like the only option is to buy a new battery, replace it myself, and hope that with new firmware battery will not be killed again so quickly.
A lesson learned is that even such companies as Sony can make crappy expensive products that will barely survive the warranty period and in no way will not admit their mistakes.
Will avoid Sony products in the future.
Sony replaced my original set after complaining. I had to jump through so many hoops to appease them first that there was indeed a problem before they would take them back. The brand new set that they send ended up starting the same issue within six to eight months. I’m not dealing with Sony again and most likely will not buy anything from them again. It’s not worth the hassle to deal with them again.
Sony used to be top notch during the 70’s, 80’s and early 90’s. They were the “Apple” of the day. No longer. Not dealing with them anymore. I spent $300.00 on these buds which are now garbage. Even people that have replaced their own batteries have had the same issue occur due to the horrible software as I understand it.
It sucks but im sure you can replace them yourself. I replaced the batteries recently. Its not too hard. I didnt have much experience with stuff like this.
@@metallboy25
Sony ended up doing the right thing and just recently reimbursed me the full purchase price for the WF-1000XM4’s.
I ended up purchasing a set of long discontinued, but still hugely popular MDR-EX800ST earbuds. Yes, they are wired, but they sound very good.
No the don’t have ANC and they are not anywhere near as convenient as TWS earbuds.
They are actually made in Japan.
The battery issue will ultimately come with every fucking earbud... because it's in there nature to have battery issue ( because of being at 100% all the time )
Mine too. Bought the a year ago and the right ones battery lasts 15 minutes and the left 25 minutes.
Don’t waste your money on this product.
I had purchased my 1000xm4 in late 2021. My right side lasts about 5 minutes and left side lasts between 50-60 minutes. I had paid around $270 plus tax. I feel my money was wasted. I do not recommend these to anyone. Don't waste your money.
Bro they are over 2 years old, just replace the battery. It's really easy and not expensive. After that they work great again.
Mine too and I got two sets of headphones.
The official service centre quoted me 6k rupees to replace the batteries for both the buds. A new pair only costs 8.5k rupees in india now😐
@@MPetersen1 They should last longer than 2 years, "bro". Especially for the price point.
@@ThurstonHowell3rd or they should have an easily swappable battery.
I had the same issue, my buds are over a year old.. so they're out of warranty. I took them to the Sony store and asked them to fix it (I was willing to pay the repair)... They weren't unable to understand what was fillings and couldn't fix it.
Thanks for making this video
Thank you VERY MUCH for this Aaron....!!!! We are all glad that someone has publicly addressed this issue and only wish that more reviewers would have the courage to do the same as you. Please keep us updated because I have yet to reach or find any resolution to this issue from Sony themselves. Your viewers appreciate you and we will continue to support you brother.. 💪🏿💪🏿💪🏿💪🏿 Thanks again
Wow, that was disturbing. Sony has pretty high standards so I am hopeful they will have a fix. Awaiting your next video
It's not that serious lmaoo million of devices get made they will fail its why they offer wearranty....also it doesn't affect all of the older ones that is misleading!!
@@Ecko92 Woah, good job the warranty lasts long enough that everyone who has this issue can get it sorted -oh no wait the update only came out after the warranty had expired for people who bought them early on-
@@joj. if you have anything for a year you got your money's worth! Buy another don't be a peasant
@@Ecko92 shitposter or serious? lol
@@joj. very serious you put them in your dirty ass ears you sweat, drop on the floor.. the charging cases are dirty af ect ect lol yeah very serious
I had my xm4s for about half a year and they seemed fine. Although, never used the newest firmware. Great video, by the way, Aaron. Your work is always second to none.
Thanks Michael. Glad to know that it does not affect every unit.
I rarely use my xm4, Total hours is just 75 Hours since purchase, but my right and left earbuds battery died within minutes now. 100% full charge, next 10 minutes, low battery notification. I sent to claim warranty and the sony store said they have been getting the same complaint.
I the same issue. Annoying for the price😡
@aaronloudnwireless do u have to ship the oem cable in order to complete the replacement or u could use another one
@@aaronloudnwirelessthey stopped selling the wf-1000xm4 at bestbuy!
Bought the XM4s in June 2021 and this issue appeared after roughly 1 year. Sent them back for Warranty as I had two years and they decided to replace both earbuds but not the case. Works fine for now. Thanks for covering this issue Aaron!
Thanks for this video, I thought I was going crazy when my battery drained so much quicker than before so suddenly. Didn't know it was a firmware issue. I hope they fix this soon.
Did that fix it?
No, they did not. I am starting to have this kind of issue after 1 year of using these earbuds. @@عبداللهالشافعي-ع3ي
@@عبداللهالشافعي-ع3يnope
My current issue seems to be the left earbud. Sometimes I get this flashing red LED when both earbuds are inside the case. Saw in Reddit that some users are also experiencing it. With this battery issue that you mentioned, I’m guessing that the latest firmware is the culprit.
I hope Sony replies back to you to clear this out and fix it with a new firmware.
Flashing red is about heat , i place mine infront of my fan to cool it down 😅
@@bellelll8926 Yes. I think it is about heat, however only the left earbud feels hot when I pull out both the earbuds. That is not normal I think.
Same Problem in my left airbuds!! How to fix this problem!
Same here. Not under warranty.... :(
Correct. That is what is happening in the left earbud. It is draining 2x faster than the right earbud and gets hot very fast. Hence, the blinking red light after a few minutes of charging.
I noticed this issue right after the 1.4.2 firmware update. At first I thought it was the case but then I noticed on the app a consistent 10% difference in battery drain on the right bud vs the left. Hopefully the next update will fix this problem.
Same problem here. The right earbud dies after 2hours. Fortunately, I bought them new last year so they're still under waranty. But this malfunction is unacceptable for such an expensive device.
FINALLY!! Thanks for listening our comments and really look through it!
After the 2.0.0 firmware update for the WF-1000XM4, my headphones became unusable. I bought it because of the confidence in the brand and the great reviews about the product, but today I see Sony's neglect and I decided never to buy anything from the brand again. Problems do occur, but I'm sad that I didn't buy another brand that respected the consumer. I DO NOT INDICATE
HI Aaron , thanks for taking time on this issue, i faced the same with my right earphone, got it replaced from service center, they replaced both left and right earbuds with old case. took 1 week time.
Do u have to ship the original usb cable or u could use another one to complete the replacement
Yes. Same here. Early purchaser, July 2021 and same issue. Right side accelerated discharge, sometimes as low as 100% to dead in 20 minutes. I got on Sony support today and got an RMA for a replacement, no charge, free shipping. I am mailing tomorrow. Sony DID apparently see this issue is legit and are standing behind their products. Commendable!
Thanks for the video series on this, Aaron and keep up the great work here...
No problem, glad it helped.
I assume yours were outside of the warranty? And Sony still agreed to replace?
@@bccsivxx-xxivvii They were outside of warranty and they replaced with a new pair! Was REALLY surprised they did, but so glad, these are great earbuds! Took about 2 weeks to get them back.
I just visited today at Sony Service Center. Mine is also out of warranty. They need to inspect my device. Need to wait 5-7days. Excited though. Hope both buds will be replaced 😊🙏🏼
Got mine today. They replaced both buds for FREE! 🥹 So happy
Let me thank you so much for the series of videos that you have post about this issue. Thanks to you, I reached sony support team and I got a replacement of my headphones. I don't think I would do it if it wasn't for your share experience in your videos. Again, thanks so much for get me a new pair of headphones
Had the same thing happen here, right earbud died in ~15 min even after disabling all features. Just got a warranty RMA so I hope that these new buds will be better. Shipped with 1.6.2 so hopefully updated cells too.
Last August I also had a battery drain problem for 1 year using the Sony WF-1000XM4, a battery that normally can be used for 4-5 hours, suddenly a low battery notification appears when using less than 1 hour, fortunately Sony wants to replace my WF-1000XM4 😃
Same here. My right bud drains so fast in just 5 minutes. Noticed it when updating the firmware.
Mine is also out warranty. I just presented today at Sony Service Center. They said no only repair, but only replacement. Need to wait 5-7days for checking my device.
@@jigokuron69 Sony knows what the problem
Thats why they replace every unit that goes to service center
Hi. I sent in my pre-order unit for repairs and Sony Malaysia had the both the units replaced after 2 visits. No more drain anymore. Prior it did 100% to empty in less than 20 minutes. Thank goodness I had a month of warranty left.
My right battery drained 20% faster than the left. Got it replaced under warranty with 10 days left in my warranty period. I hope this new pair helps me out.
What is the warranty period?
Add my voice to the screams. After less than a year, my buds are trash. The right ear battery dies after 20 minutes! The left bud lasts longer, but not nearly what one should expect for the length of time I've owned them.
Please keep pushing at Sony for replacements and keep bringing the issue your channel. Thanks for your good work! It's very much appreciated.
Please see the note I just posted. Give them a call. They should replace.
I have these ear buds for around 3 years. Experienced this issue & wanted to replace batteries... thanks for the video.
No problem 👍
It's been happening to me after months of not having problems. I'm afraid to mess with the settings and get even less battery.
My left one lasts only half of the right one. I ordered 2 battery change kits today.
Hats off to you my friend, for your attention to this issue.
I pre ordered my xm4's. Noticed this issue a couple weeks ago; I was a few months out of warranty. Online support was useless, they expected me to send them out for repair. Called Sony and escalated. Eventually they relented and agreed to replace mine with a new unit.
Got the email the new unit has been ordered so just waiting at this point.
When I got to about 10 months after purchase I noticed that the buds would only last about 2-3 hours per charge (both buds). luckily they were within warranty so Sony Singapore changed them over.
Barely any questions were asked so I assume this might be a well known/common issue.
Thanks for the information. I also felt this way on my Wf 1000XM4. Aaron, personally, what is your favorite TWS?
You're welcome! I don't really have a favourite at this moment
Thank you miter Aaron ...
I have exactly the same issue .
This could be resolved? or i have to forget about it.
Thanks for the helpful info. Contacted SONY. They were so helpful. I was out of warranty, but they are replacing my XM4s at no cost and no hassle. 😊
No problem 👍
had the same issue........ thanks for bringing this to light. I just thought its my unit issue. my xm4 was beyond 1 year warranty already. This made me NOT buy Sony anymore
Same here. Switched to AirPods Pro 2 with usb-c just for the extra protection from apple care +. I gotta admit, Sony’s sounds better but we’ll see how AirPods age since they’re my first pair
I was about to send mine for battery replacement but luckily I watched this video and am now getting new ones has replacement, thanks!
Might be worth trying to reset the earbuds. I had a similar issue on my WF-1000XM3 and resetting it worked. Seems like it was a firmware issue
Judging from my personal experience factory resetting DID NOT work, as this is clearly a firmware issue. Once you're on the latest firmware, there's simply no way of going back.
I bought my xm4 in Aug 2021 kind of 2nd batch of the launch. I really noticed more uneven drainage of battery of right side over the left. Luckily I got the extra 3 months warranty from Sony as launch gift, I sent it to Sony repair center and they exchanged both sides for me for free. Now they work fine. They said it is normal battery degradation but I only use it for 3 hours per day on average and certainly less than 500 charging cycles
This just started happening with my earbuds. This may impact more people than we realize.
My brother and i have these and both are facing the same problem. We've submitted both for repairs as they are under warranty
Same here, should i buy the new gen xm5 or should i buy airpods gen 2 instead ?
Left side drains faster for me. They are under warranty and sent them to the service center. Awaiting replacement. I mentioned to the technician that the issue manifested after the update and he said i am the 3rd one in a week to send in their unit saying the same thing
Got my replacement. They gave me a brand new sealed unit in softwae version 1.5. I think it is the 1.5 that will resolve this issue
Yea my left earbud only lasts about 6 minutes with ANC and 20 minutes without, while my right earbud lasts about 20 minutes with ANC and nearly 40 minutes without. I've only had the earbuds for about a year and the battery went from 4 hours to these times within the past few weeks. They are practically unusable.
I am experiencing exactly the same issue left bud drains out completely after six minutes of taking it out of the case I don't have a warranty ,
AERION do you think the bose quiet comfort 2 is better than the xm4s? I am thinking to upgrade
Hi Aaron, did you get anywhere with Sony customer care? I'm having very fast battery drain on the left bud, probably getting around 30 min of on-call at work :( Wonder if Sony customer support helps in any way. Thanks in advance!
Can you run a test using the latest Sony WF-1000 XM5? We want to know if the latest product has the same battery drain issues also.
Unfortunately my country does not have sony service center. I dont know what to do . I bought it when i was abroad.
I bought mine in November 2021. It is now Feb 2022 and as of a couple of weeks ago I started to notice the issue as well. I called Sony and they had me do all the troubleshooting I have been watching on youtube. After I went through it all they decided to issue me new ones. They send you a shipping label to your email, you ship them and once they receive them they send the replacement out to you. I sent mine in and are waiting for the replacement will keep you all posted on progress.
Good job, Aaron! Helpful to know and Sony definitely should do something since they claim to be 6 hours battery life (with ANC on)....and this are not cheap ANC earbuds
Thank you!
Thank you for the video, very nice . I have same issue with the Sony WF 1000 XM4. I purchased them in August 2021. I've experienced issues at the beginning with random Bluetooth connection to the phone while the earplugs were charging inside the charging case. Slowly the battery life was dropping, now they are almost unusable, battery life under 40 min and the charging case will be empty after charging the earbuds for one time. Also I've noticed that after charging, the right earbud is significantly hot and the left one is not and also the left one has little bit higher battery life. Thank you for the video
Same for me
Late to the party, but I just found out this firmware update is what happened to my out-of-warranty earbuds! They stopped charging completely a few months ago and only heat up instead! No more Sony buds for me ever, second model with major issues for me.
This was a very clever and excellent testing procedure. Good work. Question, how can I find out if my XM4 came from an early batch or a later batch? Is there a serial number sequence or something in the app that can give me an idea?
bump
Maybe newer ones come with 1.5 firmware out of the box like mine ? Just bought them a week ago, older ones seems to have 1.4.2 firmware
@@reza.km1992 ahh, okay. mine does say 1.4.2 and it did do a recent update in september. I haven't gotten a newer update. I bought mine refurbished by an authorized sony refurbisher. I am going to do a test like the Aaron from the video does to see if I have the same problem.
If it didn't come pre-installed with firmware 1.5.0, it's a previous batch. Seems like only sets purchased in August or newer has that.
@@aaronloudnwireless Thanks Aaron.
Thanks for bringing up this issue. I've been dealing with a similar problem for a few weeks now. Now I can't use my earbuds any more. So frustrating.
The case flashes red non-stop when charging it. And the moment I put them in my ears the left bud dies under 10 minutes. It's so bad that buds have been rendered unusable. I'm disappointed.
Here because I bumped into this as well. Really annoying and it's probably why there are so many recertified versions out there for sale -- the right drains faster for sure, but they can now only hold a charge for about 45 minutes compared to the hours I got before. I'd be curious to know if they just used poor-quality batteries or if the way they designed their charging circuit in the case just constantly cycles the battery (e.g. keeps topping it up and doesn't turn the devices off).
I see some have had luck with Sony support, so I may go that route, and see what they say.
Hi Aaron , I haven’t come across any issues yet with my xm4’s. It’s been around 4 months I have bought this product. I guess I’ll have a problem sooner or later. I have checked the serial number and it starts with 7 ,so i assume it’s the newer batch as the older ones start witha 5 and 6. Anyways if any issue occurs then definitely I’ll go for a replacement within the warranty period (8 more month remaining).
Thanks for your video👍
Same happened to mine, but i never updated, and thankfully i got extended warranty from third part which fixed the issue, just by replacing its both batteries
Glad it was resolved!
I called SONY. I told them this was a safety issue as underpowered batteries would heat up with a new firmware upodate causing them to pull more power than they were designed to handle. I relayed the reported cases where the buds have actually exploded. This can't happen with something that goes in your head. Sony agreed to service the buds at no cost. After about a month at their New York service center a new set of batteries were installed with new touch pad sensors. I still get this issue occasionally where one ear bud disconnects but not as frequent as before. The sound is AMAZING. Also, I did not have the receipt anymore (long story) and they replaced the units anyway.
Unrelated, I want to add a story of how I put them in the my jeans pocket once without the case very early on when I first received them back in 2022 and they accidentally went into my washing machine....a full cycle underwater! That must have been at least 30 minutes. I opened the case and when they weren't in there I instantly screamed SHIT!! I ran to the washing machine and pulled them out of my jeans and put them in a sock and ran them in the dryer for a couple of minutes until the sock felt warm and then let them dry for 3 days turned off obviously. They worked PERFECTLY. I don't think you're going to get that kind of build quality with anyone else. I was happy for the next two years until the big firmware update. I no longer install firmware updates until the update has been out for months and months. If your buds work fine no matter the brand don't update the firmware. I just went through this with a pair of Beats PowerBeats that I got NOS because I was impressed with the microphone quality after watching a guy on TV do a live interview on Zoom using only those buds. My first Beats product in 10 years or more. Great battery life probably because they dont have ANC and crispy clear phone quality but for use only on phone calls that's all I need. Then I did the Beats firmware update and one side started draining before the other bud had even reached 60%. I had to reset it over and over again. What a headache. if the two largest earbud makers can't figure this out then I wonder what the smaller brands are dealing with as far as bugs not mating with hardware on the decline (the battery).
I had the exact same issue with my right side earbud but mine was under warranty so they replaced the old ones with new (both) buds. The charging carry case was not replaced but I got brand new buds which were surprisingly light weight when compared to my defective old ones. :)
Do u have to ship the original cable in order to complete the replacement or u could use another one
That is really good of you to reach out to them. They have to do something about it as it is nowhere near good enough. I've not had this problem but now that I have just said that then I probably will! I am on ver 1.4.2
SAME THING happening to me! Really bummed a recent trip of mine. Please let us know!
@Aron is Loud and Wireless try turning off google assistant, it helped a lot.
I didn’t have that turned on, but it’s true that GA drains battery also
I switched the Google Assistant control to the left bud on my XM4, and now the left one drains faster, but in a much more balanced way. Now the left one dies after 6 hours when the right one has 10-15% of battery left, whereas before the right one used to die after 4.5 hours when the left one had 35%. Just invert the leftright touch controls and it'll be much better.
I'll give it a shot thanks
My left ear bud started doing this and I just updated to version 2.0 and still no change. Any information?
This issue happened for my xm4, Right side had drain issue. Luckily my device had 45 days of warranty left. They replaced the right side bud only. Then due to battery health difference left side was not keeping up to the right side duration. Then left side was replaced. Hopefully now as the warranty is expired this issue does not happens. Now will only update if required.
Yep it's happening to me. Got mine last year and all a sudden my left earbud dies in less than an hour while my right still has 86% it definitely didn't do that before 😞
Wow. Thanks! I've noticed my right bud come out of the case at 90%. Now, I know why.
Hey Aaron I have the same issue with wf-1000xm3 could it be the same or just old age
Probably old age
Yeah the right earbud has been draining slightly faster than the left for months now, but I still get around 4 1/2 hours of listening so I never thought much about it.
same here I guess, and I get about 1.5-2h with ldac 990kbps + dsee extreme on, which is fine for me (enough for a workout :p)
The problem just started during my trip to Paris.
Left and right earbud don't even notify me when the battery is low anymore and they don't even last / barely last an hour without anc and ambient sound (Left 45min, right 60min). They last a good 40 minutes with ANC on.
Such a shame, I emailed their customer service but the earbuds are no longer on warranty. Should I expect them to just refuse to replace them ?
Purchased mine in 12/2021. Don't know when the problem started, but I'm on firmware 2.0.1 now. But I'm only getting about 20 minutes out of the right one now. I contacted Sony online (chat support). They've asked me to send my earbuds and case in to service. They are going to re-pair a new (probably refurb?) set with the case and send them back. So they do seem to still be replacing under the (unpublished) extended warranty. Still probably cheaper than a recall for them.
I had the same issue. Gave it to the service centre, they replaced the right bud and gave it back. The same day, left one started draining. It's been in the service centre since then. It's been already 2 weeks and no response. Really disappointed with SONY.
I successfully replaced the battery on my set. Works fine now
Just switched under warranty. After one year usage mine hit same issue suddenly within one month. Many suspect it's the firmware 1.4.2 issue that came in July or what. New pair given under warranty and come with firmware 1.5.0 Hope it's really the firmware issue
Yes i have same problem, mine is pre-order first batch.
i) left erbuds drain faster
ii) Casing always drained while not using
iii) Red light comes out every time charging, and earbuds is hot as hell.
iv) after reset the earbuds using closing lid 5 times, battery can spike up from 36% to 76%. So Magical.
v) As Malaysian Engineer, fell Shame to Malaysia Sony Manufacturing Quality Control/ Assurance Engineering Team.
vi) left xm4 aside and now i using Samsung earbuds 2 which is more stable and durable.
Just tested it today. In my earbuds, when it reach around 75%, the right earbud start to drain faster than the left one. Got battery low notification on 45 mins and died in 50 mins time. I purchased the XM4 in September 2021, So also not under warranty
Omg, Im having the same issue except both sides only last like 40-50 mins. Thanks for talking about this, I've been checking online to see if anyone has this issue. I bought my earbuds when it first came out and updated to the most recent firmware. Been trying to see if there's anyway to downgrade or roll back firmware.
Mine were replaced by returning them to the store where i bought them. I had the same Issue with the right bud and the left bud didn't charge full. It stacked by ca.90%. I bought them in August 2021. The replacement happend yesterday...
mine are having issues recently. right earbud is fully charged but after one song it says battery low and hardly after 3 songs it turns off while the left earbud continues to play flawlessly. More amazing thing is the minute i put both earbuds aback into the case the right bud again shows fully charged. So expensive earbuds and such issue by Sony. Even my 1500 bucks Blaupunkt earbuds which are 5 yrs older than 1000xm4 works flawlessly till date
mine are left 75-80% and the right 10% and it usually stops at 10%... It was not a slow progression to come to that end but just one day in the gym the right one went off super quick and then every time the same
On the day i decided to get the xm4's. Gonna wait this one out cuz i heard units with 1.5.0 still had the battery issue. Airpod pros gen 2 look really tempting now...
Yes, got issue with right ear bud draining in about an hour. When charging it gets hot and the red LED blinks near the time its about full. Had them for about 1.5 years, the issue started about a month ago. I cannot upgrade to latest version. I have Ver. 1.4.2
Trying my luck here. Might get a reply.
Will it be possible for you to provide an EQ setting for the XM4s that is somewhat close to how the APP2s stock EQ sounds?
Just use 2 4 7 7 5 on the equaliser. So far it suits alot of people on Reddit
How long is the standard warranty period, 1 year or 2?
Had to send in mine last year or a couple months ago, got a full replacement, and the left bud started getting battery issues recently... but the replacement isn't under warranty.
Which firmware
I have one of the more recent ones and dont have this issue for now however the right side is always draining a little quicker which seems strange
I have replaced the right side due to the battery drain issue on about 7 months of purchase , now just over 1 year warranty the left side started to have the same issue .... good work sony ....😢
Yes. myself also get the same issue.
I have the same problem except its the left
After your video, I tested my WF-1000XM4 which is also amongst the first batch too and also out of warranty. I am also on the latest version of firmware.
I tested it with my normal use plus extra 20 mins on my ears to see if I have the same problem.
Luckily I don’t have this problem.
However, it is true that the right ear bud uses more than left. My right earbud after 1 hour of use has 81% whilst the left earbud is at 82%.
Awesome
Mine have just started doing this and even developed new issues like charging case flashing red with earbuds in and no charging cable or pad connected. Mine are 15 months old and it seems Sony are going to fix it no questions asked. I assume warranty period was only 1 year but guess they know the issue needs to be sorted.
I'm also having the same problem, left earbud drains very quickly. Problem started 2-3 weeks ago. Bought 14 months ago, so no warranty. Is there any way to roll back the firmware?
So replacing the batteries even after the 2.0.0 update won't help then, yeah?
Thank you for bringing this issue to light, Aaron. I think you're the first youtuber who brought up this issue.
I have had similar experience as well, I pre-ordered my pair last year, and I was using the XM4s for 6 months. After 6 months, I began noticing that my right earbud dies off way quicker than my left, and the discrepancy is about the same as yours.
However, what's more disturbing about my issue is that it is before the firmware update of 1.4.2 (I updated my firmware after Sony replaced my first pair).
It's also noteworthy to mention that there are a lot of Reddit posts with the exact complaint. So, thank you for writing the email to Sony, and do let us know what Sony says about this issue.
Hopefully, for those who are just experiencing the issue now, I hope that they are willing to do some sort of compensation (like the replacement programme as you mentioned).
P.S. My battery issue was fixed after replacement.
both my right and left earbuds drain so fast even i dint use the earbuds very frequently. total listening hours is just 75 hours since purchase. Its been 2 weeks and the sony service centre said "We are waiting for spare part". I thought they are just changing the battery? LOL
My left earbud will still be over 80% by the time my right one dies just started having this issue yesterday but luckily you can get these batteries easily now
I also had the same problem with my WF-1000XM4, I bought them in the end of June 2021, and I realized month ago that right earphone battery only lasts for one hour. In my country (Poland), there are two years of warranty, so I sent them to shop and after two weeks I got earbuds back with information that they replaced left and right earphone (case stays the same). Now, everything works pretty fine, and version of firmware is 1.4.2.
Feel like you should request them for firmware 1.5.0 just to be safe. At least in Singapore the switched pair come with 1.5.0
@@fantasytky28 1.4.2 is working fine on the newly purchased came along with this device. No worries 😌
I have the same damn problem. The right earbud heats up like crazy and case battery drains super fast. I’ve only used mine for 8 months or so. I cannot return it because I bought it in a different country.
Great video, basically im having same issue with ones bought in sept 2021, so i guess also an early batch, i sent them to sony for service, hoping for a good result, will update when i hear, great video on this an others, thanks!
im having the same issue .... QQ did any of you folks have the battery replaced and did it work after that. thanks
got mine free with my xperia 1 III last Dec 2021... just recently the left bud started draining so fast it lasts just over 30 mins... luckily still under warranty, just picked up today, both buds replaced...
Started for me. Left 41%, right 6%. A few months after the update to v2. They both also don't change up to 100%, only 80-90. Now they last 1h 😢
Created a service ticket, I hope they will fix this on warranty.
I am experiencing the same problem 😭😭 how do I fix this issue🤷♂️
The same thing happening to me. getting under 1 hour but on my left side. On firmware 1.4.2. Have 2 months left on my warranty. Think ill go and replace it immediately
I purchased mine in beginning of January of 2022. Left is ok ( longer than right one). Right one lasts 40 to 45 mins. Now running 2.0 upgrade, was doing the same thing on previous update (whatever it was). 13 months later Right after warranty expired
