What's the real reason that laptop batteries are made not-accessible?

What does that have to do with this? Both of my iPhones use pouch batteries, just like the Samsung device mentioned.

And as I mentioned earlier in the thread, I have an iPhone 6 from 2014 and it's original battery is still showing 92% capacity.

I imagine to wear out a battery enough to need replacing you would have to charge/discharge it several times per day?

I use Waze a lot in the car, and it is a total pig on power, and makes the phone baking hot to boot.  The most recent battery I fitted is a massive external "piggyback" item with 6000mAh capacity, which is enough to run the  S5 for a week - if you don't use Waze!  :)

I normally get 1-2 years out of a battery.  I've recently adopted a new habit of only charging to 85% capacity, in an attempt to make the battery last longer, let's see how that works out...

My wife also uses an S5 with a piggyback battery, and it also burns out its battery in 1-2 years.

(What I call a piggyback battery, is one of those extended batteries with extra capacity that are so big they come with a new back cover for the phone to be able to contain all the lithium ions!)

I carry an even older phone, a Blackberry Curve, which is so ancient that kids giggle when they see it and start asking questions about what it is...  "It's soo tiny!!  Cute!".    It has also always required a new battery every 2 years or so, for more than a decade -  the batteries eventually lose performance and start to swell.  Swap the battery for $5, and it works like new again.

Maybe they are thinking “epoxy” and “superglue”, when in fact almost all of it is advanced adhesive tapes. (If you’ve ever used 3M VHB tape, this is the class of product used.)

I have swapped screens on a couple of "sealed" phones, I am not completely unfamiliar with the types of adhesives used.  - I dislike the combination of a sealed battery, wireless-only headphones, and no SD card.  The modern flagship phones have much better computing performance, but no (or crappy) peripherals! :D

SiliconWizard:
Yeah. Batteries are held in place with this double sided stuff. Heck, most of the time, there's even a strip underneath that's supposed to make it easy to remove the double-sided tape and thus the battery. In practice, after a few months of use, with regular heating from the battery, the double-sided tape becomes almost impossible to remove this easily. So the strip is great for servicing batteries after just a short time of use - probably for phones still under warranty - but after 2 years or so, that becomes a lost cause and removing the battery almost always imply fighting with the adhesive and eventually butchering the battery, hoping you don't damage it enough for it to leak or something. Yes, done this a few times... :-DD

I think the disappearance of SD cards is surely due to pervasive availability of wireless networking and cloud storage?

My current phone has a 5G data speed about the same as my wired ISP. It seems like you only need to keep things in local storage that you have an immediate need for. Other things can stay in the cloud. How many movies or podcasts can you watch during one plane ride?

eti:
Customers are told "You need new things", and they dutifully oblige. That, and "retail therapy" being something they falsely believe will fill the void in their (sometimes) unhappy and unfulfilled lives.

I'd rather proudly stamp my name on a product that will last 20 years, and offer maintenance of it as a service, than undermine my morals and keep selling them shite that I KNOW I've produced to purposely break down. Never ever would I do that. Even if I saturated the market and no one came back for another one, I'd be less well off but my conscience is more valuable to me than endless millions I don't need or will never use.
