AravindAnil yes that’s right even i went to service centre and they replaced with new one and now im facing the same issue. Guys if u get a new buds replacement then dont update the firmware.

I think oneplus earbuds are much much better than nothing. Very worst batter backup in both nothing 2a and earbuds.. Am ashamed to buy this brand. Am suffered lot while travelling.

Except os, themes and widgets there is nothing in nothing.

I have a November build of the buds, they still work but I notice that the master earpiece changes with every setup. I would like if they added solid state batteries as they are more stable and is loaded with more power.

Hello. Bought them in July last year. Now I’m getting about 3 hours battery life with ANC on. I’ll disable the case buttons and see what happens. But it feels like battery is degraded.

Update…

After turning off buttons on the case, I’ve gained 1.5 hours or more. It’s still not advertised 6 hours but hey, this makes me happier.

I used to deal with this problem and had two replacements. I found out it’s firmware updates which cause this. Upon the suggestion from someone in the forums, I got a replacement and never updated the firmware (it runs on firmware 0.0.5.5) and I never faced this issue again. Hopefully this helps. Cheers!

Wish i read this thread earlier and never updated them…. Just bought them yesterday.

In my personal opinion, these are the worst buds you can buy in this price range. My 4 year old oppo enco has a better battery backup than these.

Now I am also having same issue of One bud at 95% and other at 100%….. This makes me fear that these will also go bad as some people are mentioning.

Hey! I’ve been using these buds for almost 6 months now while having to replace it 3 times so far. It turns out the firmware updates make these buds worse, i.e. terrible battery life and not full charging. When I got these pair of buds (the replaced ones) I never updated the firmware and the battery life is far better and they full charge. Now the question is this, is it really safe for me to upgrade to the newer firmwares maybe? Have they fixed these faulty firmwares yet?

Seems like the CMF Buds 2 are just around the corner and seeing how we have got no real fixes for these firmware issues in spite of everyone talking about it just seems odd. The actual buds with the base firmware perform extraordinarily well and it just makes zero sense how they are nowhere near on the latest firmware yet, they never pushed out a fix but are now releasing a new product.

I really don’t know how to feel about this, I’ve never seen the CMF Buds have any of these issues. The only reason I bought the Buds Pro 2 was the better battery life but yeah. Thank you for reading and please let me know if the battery life issue has been fixed with the updates.

Also here’s the proof that Buds 2 are soon:

Hey, I’m telling you that I sent my headphones to have their batteries replaced (unofficially by Nothing, since there isn’t one where I live).

I made a post asking if anyone had changed the battery manually, but it was deleted. I’ll let you know on Monday if the battery life is improved.

Andr_sFelipeMontielG sounds good!

I cant be the only one without issues, my build date is November 2024, had to update to 0.0.8.1 and they still work. Its either the overuse or the weather. I live in the Nordics and they work and are OK,I didnt want to spend a ton on headphones. either people use a 4.2 bluetooth phone with the buds which is just bad for yourself.

Ori

we_are_a_small_company I decided to just update the firmware right now because yeah. Let’s see what happens. Hopefully it doesn’t break, I’m legitimately praying 🙏🏻😭

Andr_sFelipeMontielG hey! like I mentioned in the earlier post that I decided to update the firmware, I was stunned to find out that the update never caused the brutal battery drain for me. Every other replacement had a terrible battery drain after updating the firmware but this time, somehow the battery is just as good and it drains very evenly. I’m not sure what’s exactly happening maybe QC were not so good for these buds because 2 times back to back I had faulty units but this time it’s working without any issue at all.

Edit: Both of my buds are full charging as well.

we_are_a_small_company hey, I have a very weird and random question, did your buds come with a white cable? My earlier models had black wires and they were faulty. But this one came with a white wire (I was confused) but this works with no issues at all, so I was just asking.

Andr_sFelipeMontielG

Hello guys, I’m back.

Today I received my cmf buds after the battery was replaced by a third-party technician. To be honest, the problem with the battery drain is still the same. The problem is now software-based, and there’s nothing to solve.

Although the battery is brand new, the discharge is very brutal, so it is not worth changing the battery. Although the battery is brand new, the discharge is very brutal, so it is not worth changing the battery.

raal I’ve been having issues with Battery life too. Especially when on phone calls. Barely lasted 20mins on call. The recent two firmware updates have been brutal.
