This worked, thanks. Words of warning for others - 1 - be careful near the front edge because you can easily damage the led on the board. I killed one of the LEDs this way. 2- If your touch sensor is wonky, try restarting (putting it back into the charger) - it will work again.

You can also use the new Varta CP1254 A4 batteries, as they have an even higher capacity than A3. The warning in the video is to make sure you don’t buy A2 batteries, which sellers on eBay often list as ones for repairing earbuds, but as mentioned, those have a lower capacity than A3.

Hello please can you help with Amazon line you bought from, I can’t find the batteries

Thank you for this video! My right earbud had gotten down to just over 30 minutes before running out of battery. Bought some new batteries and followed your video. Again thank you, very much appreciated!

Thank you so much for this! I love my headphones but after a few years of heavy use followed by the pandemic and almost no use batteries were pretty dead. You, kind sir, saved me a few hundred dollars for new headphones and prevented generating unnecessary electronic waste. Big kudos! One note - when lifting the battery - it's much easier to do from the side where the ribbon is. If you go from that side you're also more likely to only extract the battery which saves you the effort on re-aligning the contact

Thank you for this guide ! My left earbuds has only a battery life of 4 mins and the right earbuds a battery life of 30 minutes after 2 years of daily use in public transport, at gym and by traveling.

@Tom Tl i keep reading about all these battery break thrus online, but when will they come to actual products? i went thru 3 plantronics due to this issue.

Tip for anyone that finds the touch controls aren't working when you put the top cover back on. I found the touch controls worked fine with the new batteries without the top cover, but as soon as I put the top cover back on, the touch commands stopped working (for both buds). I found that I needed to reset the buds. Put the buds back in the case, the red LED (per bud) should light up indicating charging. Press and hold the touch button (one bud at a time, with the buds in the case, and with the top cover on). After around 15 seconds the red LED will start flashing, keep holding the touch button. After a couple more seconds the LED with flash faster, then a couple more seconds the LED will turn off. Once the LED goes off, stop pressing the touch button. The LED will come back on after a second or two to indicate it's charging again. Repeat for the second bud. Once I did that I found the touch commands were working again. The reset will not change any of your pairing settings, so you won't need to re-pair to anything. It's weird. Obviously the touch is working to some extend, otherwise the reset process wouldn't work, but when paired with my phone it would not work with media commands (play/pause/skip) without me doing the reset.

Thanks so much for posting this. I love these earbuds and hated the thought that I’d just be tossing them once battery life was poor (its getting there). Glad to hear they can be replaced even if it is a little tricky. Even better still you provided evidence as to the improved battery life with good testing technique.

Thank you!!! My headphones were only getting 30 mins of play and this has breathed new life into them!!!

Omg we need more tech where this is possible! Happy to have bought them

Je n’ai pas ces earbuds mais je ne peux que reconnaître que ton tuto est super. Merci !

Great guide, thank you! One thing that was different with the battery I got was that the side with the writing on was the POSITIVE side, I very quickly realised and flipped the battery over and now all is good. Also, I had to be careful with the ribbon cable that is attached to the touch sensor when first opening the ear bud up as that was attached to the outer casing.

Well, I think I messed up the LED indicator, but the Left earphone I've worked on is working perfectly! Amazing guide! Thank you!

Awesome, I just finished replacing mine. The new batteries came fully charged with a small tab on both sides for some reason, so i put the battery in with the tabs pointing into the battery and held it closed for a few seconds to see if the led would start blinking, but immediately notice the battery getting hot. so I removed the battery and installed it with the tabs facing the opposite direction and checked again for heat and power, and it worked great. Tested with charger and phone, no issues yet.

This worked. Thanks so much. Picked up the Ifixit kit as well. Seems excellent for the price

High Quality video keep up the good work!

I’ve had mine since early 2020 and they’re still amazing, not a single issue with battery life and I use them every other day or so only requiring a charge once or twice a month. I do tend to listen to fairly low volume though so maybe that’s why they last so much longer Edit: forgot to add, watching the video in case I need it, wanted to confirm if the battery was replaceable or not 😂

Just performed the replacement successfully, thanks for this video! couple extra thinks to look out for: 1- as other said, look out for the led's on the bottom of the board, take your time and open the perimeter in small steps, do not go deep with the picks. 2- my replacement batteries came wrapped with an amber, adhesive tape film that needed to be removed prior installation 3- watch out to not short the batteries! the metal contact bends upward and that upward part needs to be phisically distant form the side walls of the battery. I made this mistake initially and the battery got very hot. Luckly I was able to recover it but be careful! 4- removing the old battery was quite more difficult than shown in the video. Personally the best tactic was to really push down with the plastic lever to really get under the adhesive before prying.

@webboy998

video is generally very useful however around 5:12 how the OP placed the battery onto the metal plate is wildly dangerous. After removing the old battery you should put the metal plate back to the frame to install the replacement battery. On the frame there are two extruding bits aligned with the holes on the metal plate, the hole closer to the battery will allow the extruding bit on the frame coming through to prevent the side wall of the battery (plus side) from making contact with the metal plate which is already connected to the minus side (the side with engravings).

Thanks man! I follow your instructions and replace the batteries by myself, you just forget to mention that the metal sheet which is attached to the battery must not touch the side of the battery itself because it causes a short-circuit. by the way, after more than 2 years I needed to replace the batteries because they hardly ever last for more than an hour. Now after first test they last for more than 2 hours! Notice that! always head for Sony authorized repair shop first and ask them for replacement.

Hi, where did u get the A4 batteries from? Cant seem to find them anywhere for sale, particularly in USA.

HOLY SMOKES! I bought these exactly 2 years, 1 month ago and the earbuds discharge at an unequal rate. The left one discharges considerably faster than the right one. Plus: The left one discharges completely after merely 30-40 minutes of use :( I was considering buying new ones, as they have dropped in price significantly (about 100€) and they are definitely the best true wireless earbuds i've EVER had. That was until now because i absolutely did not realise how stupid easy the batteries are to replace!! I was absolutely convinced one could not open these without totally destroying them in the process. Thank you so much for this video!!! I will be replacing the batteries myself ASAP!

Great guide! I just upgraded to A4 version which has the higher capacity and it works great!

Thank you, that worked well. I was a little bit surprised that the batteries where already that bad after "just" 3 years, but i guess it is because of the size.

hey good video, things i learned while trying this 1. the flex cable is really... REALLY fragile, especially if you have an old one, don't bend it. i bent mine and it basically broke clean off. so now i don't have touch controls on 1 of the sides. waiting to see if charging still works, hopefully it does. but sound definitely comes out 2. when you're prying it off, there are tabs/clips that can very easily break off, try not to pry on 1 side and rotate around like i did. that'd break the tabs for sure. 3. get the varka batteries. i cheaped out and bought some batteries from china. worst decision ever, as soon as i put the metal tab, it made contact with the positive side and turned my battery into a heater. this one should be pretty obvious but.. not for stupid old me lol good luck to anyone trying this, take ur time, be careful

I like videos like these. Thanks brother. Liked!

Thank you for the video, helped me immensely. When I reached out to Sony Pakistan to fix the earphones, they said that they could not import the official batteries, and if I was able to source them they would charge me to fit the batteries, plus they mentioned that they may bear marks due to opening the earphones. I was able to follow your video and there are no marks, am charging the earphones, so fingers crossed.

Hello Saroua, would you be comfortable doing a tutorial on how to replace the battery in the charging case? I know you have to do some soldering, but it would be helpful to not replace the case once it barely holds a charge.

Thank you for the tuto !

Thanks so much, I changed the left battery, it worked well during a couple of weeks and then it suddenly stopped completely : absolutely no sound in the left one. Any idea please ? I replaced it again but it didn't change anything. Regards.

I got carried away and disassembled the whole thing, I took them apart in the first place to fix the 3 charging nodes not making a connection and the middle one being in too much. Idk if I can put it back together

Thanks for this. My right side earbud is crapping out. I'll try replacing the batteries following this guide. The link to the battery no longer works. Is there another source you can recommend?

I broke the glue trying to remove it. Any idea what glue I could use instead? (I tried without, but it's not working)

This is why manufacturers are not keen to repair or replace the rechargeable batteries which would actually save the environment from more e-waste. I replaced both batteries as they were losing charge fast. It looks easy but you will still need a little patience and TLC as this are pretty small earbuds if you have huge fingers. I bought a pair batteries online which cost $18. The tricky part is placing the battery and it's metal connector with double sided tape. Before you close the cover, you can actually put the earbuds on the charger to make sure the red charging light appears. If it's blinking or no lights, it means the battery is not sitting or connected correctly.

Thanks for a great and informative video. Any idea if the case battery is possible to replace?

Hi Saroua, thanks for your video which comes at the right moment as my wfx3 are dying to fast.

Do you think they could be compatible with wfx3? thanks

@photonicpizza1466

Жыл бұрын

They will be compatible. The A4 batteries are newer generation batteries from Varta. They weren’t available when the WF-1000XM3 were designed, so the batteries installed originally will be the A3, but you can use the newer batteries. The warning in the video is mainly because of sellers on eBay selling A2 batteries very often, which have a lower capacity so they would be a downgrade, but the A4 batteries do indeed have a higher capacity (and practically identical charging characteristics) so they will be an upgrade.

Thanks for this awesome guide !

My right earbud has no sounds. How can i fix it? Any suggestion? Touch controls are working

hello, have you replaced a battery in the "WF 1000X" ?

after changing battery, the light indicator on the headphones are gone, any fix?

My replacement batteries came wrapped in yellow tape that I had to remove. They also had tabs that I had to break off. They worked awesome the first night but once I put them back in the charger overnight the left one stopped functioning. I completely disassembled it and the battery was too hot to touch. I tried to rotate the battery thinking that it might be shorting out on something. IT no longer overheats but that earbud stopped functioning. I would guess that I fried it somehow.

inside under the cover is a flat capacitive sensor coil. There is a black jelly-like plastic there and it serves as a seal or glue to transfer the charge from your finger through the cover to this sensor. So after the headphones are assembled - the sensor stops working because this glue is disposable. Having torn it off, it no longer conducts the signal for the reason that the contact is not tight. How to glue or what to replace this glue?

Maybe you can help me. I changed the battery as instructed. The earbud will function but not load and does not give a red light. The case itself shows a red light, even if the other earbud is not present. What can the problem be? And is there a solution? Thank you

Thanks.
