Cayin N6iii: Nothing is Impossible with Gen2 User-replaceable Audio Motherboard

Jan 23, 2025 at 5:34 AM Post #425 of 677
Cayin have replaced my n6ii battery for reasonable cost and minimal fuss. My unit still going strong now for 5.5 years.

Enjoy the device and the music. Surely battery replacement a minor and very occasional concern.
I have never even had the need to replace my batteries as long as I kept making sure that I charged the batteries in a proper manner. This inludes making sure never to exceed 80%-90% charge ... The only real case of a battery losing its ability to keep a charge was with the Hiby RS6 ... And even Hiby have learned from that.

Dear product engineer @ Cayin!
It's kind of funny you have designed a changeable motherboard, but you forgotten about a changeable battery, in a flagship dap over $1K!
If i were your boss you would be fired immediatly because of this key mistake!

I am hoping that cleverer guys from Hiby will pick up this idea, @Joe Bloggs
A change battery is nice but really all that important and also really the exception versus the rule. How many other players make it easy?! Off the top of my head, iBasso is really the only one that really does it.

Do we even NEED to be able to charge the battery? In the time my Cayin N6iii has one charge cycle, my iPhone has had 5 or more. The iPhone is 3 years old and has 87% battery health. Assuming they use somewhat similar quality batteries, battery health will not be the limiting factor on a DAP’s lifecycle.

From a companies perspective, it’s probably not ideal to have customers opening their device and changing their own battery.

I‘ll admit, I like the idea of an easily changeable battery is appealing but if you look at it objectively, it’s not all that necessary.

lets assume one wants to replace a battery every 5 years.. lets be honest, in 5 years audio is going to be on a whole nother level anyways. we're in the midst of artificial intelligence booming, we may even live to see it take over our lives, and I'm all for it, hopefully I'll live by the time we implement audio chips into our brain and have whole concerts in our minds without damaging our ears.

Anyways yeah non replacable battery aint too bad

Changeable battery? Go to iBasso. Even changing modules is very easy and changing batteries isn’t that straightforward when the provided battery isn’t readily available.

Sorry folks, the fox is about to go into hibernation zzzzzz

Actually, it’s because the Chinese Lunar New Year—a traditional holiday similar to your Christmas—is just around the corner.

It’s a time for family reunions, so our factory is already on holiday. This means responses might slow down significantly.

About batteries—when you think about it, five years is a pretty long time. Honestly I kind of agree with @justsomesonyfan's perspective: a lot can change in five years, and something look cutting-edge today might already become outdated by then.

Of course I’m not taking sides or criticizing anyone here, if you feel that way, then I'm really sorry, but that wasn't my intention really.

Just imagine—five years ago (since it’s early 2025 now, let’s stretch it a little to make it 5 years and 1 month—so, in 2019)—back then, HiBy had just released the R8, and Shanling introduced the M6. Or if we look at smartphones, Samsung launched the Galaxy S10 in 2019. I loved the S10 for its cool aspect ratio and sleek design.

But what's now, the R8 series already has a second generation, and Samsung is now pushing foldable phone, even the sixth generation. From a technological evolution perspective, these things were unimaginable back then. What seems cutting-edge today could very well be obsolete in five years.

That said, Cayin usually keeps spare parts in stock for many years, often well beyond five. For example, the N3Pro’s battery is still replaceable even now. So, there’s no need to worry too much about battery issues. If it fails, just reach out to us—we’ve got you covered. Plus, our repairs are done at cost, with no additional labor fees or hidden charges, we ain't taking profit from repair service, it's purely a commitment to support our beloved audiophiles.

I normally look at the replaceable battery issue because of reseller value: If I want to sell a laptop or DAP or TWS after 1-2 years, if the battery is down to 50% of what it once was I don't even have the guts to sell it any longer. That also means I won't buy a new one myself, so you won't sell a new one either. 3rd consideration is that I won't buy a TOTL pre-loved DAP either because of possibly (very) limited battery life left.

In the end I hope that all portable gadgets at some point have a replaceable battery or become prohibited to sell in at least the EU. I have to add that as long as batteries do last 5 years then my points are mute, but that is rarely the case. My opinion would change overnight if instead of batteries being replaceable they get a guatanteed 5 year life span.

Just my 2 cents of course.

dongles will probably take over daps almost completely

phones will take over 90% of photography, even for professionals

even nowadays, there are phones like the vivo x100 ultra, that can compete with professional mirrorless camera around their price point, and even beat them. And we're talking a full fledged flagship device, which means you're getting insane value.

to me, it really feels like a matter of time. when Ai robots become something that is implemented in society, good chance most people will have no jobs, and the norm will be to just LIVE. atleast, that is my guess.

Wall-E came out a long time ago but that concept really isn't too far fetched.

edit: just to add, the first iphone came out in 2007.. not even 20 years ago, and the progress since has skyrocketed in ways unimaginable.

if before Ai and technology we advanced yearly in a formula of x+1, then after it we advance in x²

For example, the N3Pro’s
N3pro is one piece brick (and cheap), no one minds that way

But once you start going modular, sliding parts in and out, it's kinda crazy not to make a modular battery. It's absurd thing when combined, so you can upgrade yourself a motherboard but you're stuck with a non removable battery with no choice of capacity you need, that in a few years gonna die, damping the daps reselling value next to nothing.

All I want to say it's ugly designed modularity I don't like to support

Is it really that daps batteries are dying like that? I mean I am not primarily dap user, I do listen to daps maybe max 1h per day. (currently waiting n6III to arive though)

Comparing to my mobile phones of 15hrs per day of usage and 5 years of battery just slightly having less capacity than when I bought the phone, is it lower quality battery in daps or something else? I now use fast charging of my phone each day 3 years in a row without noticable reduction of battery. So how would this translate into daps if one uses them couple of hours per day and shuts it off when not use? after 10 years battery will be 80%? maybe I exaggereted a bit
