You could make a LiPoly battery with a hard user serviceable hard shell but it would have far less capacity than a glued in battery. Not only would the volume of the hard case take away from electrical storage volume but there needs to be free space for the electrolyte material to expand when it heats up. Batteries heat up when charging and discharging in addition to heat absorbed from components like a phone's internal circuitry. Without expansion space the battery is just a small bomb.
Older cell phones and smartphones had far less power draw than modern smartphones. The old Nokia BL-4 batteries were around 800 mAh. The original iPhone's battery was almost twice the capacity and a modern iPhone is 3-4 times that capacity. Smartphones would weigh twice as much and easily be twice as thick if they had replaceable batteries with the same capacity as their non-replaceable ones. While you might be fine with phones being thicker most buyers would rather have the thinner and lighter phone if the extra weight and bulk didn't offer any extra run time. They definitely wouldn't go for phones that had a quarter of the run time because they could replace the battery themselves.
It's not a conspiracy, it's just battery technology and physics. Also concerns about safety by way of insurance liability.
Edit0: specs: https://www.samsung.com/us/business/products/mobile/phones/g... - 4000+mAh battery.
Non-replaceable batteries are a net benefit for consumers most of the time. They get the lighter thinner phones with all the features they want. If you want to keep the same phone for a decade, even with a replaceable battery, I wish you the best of luck. In the US I don't think there's any active 2G service and 3G services will be turned off in the near future. It'll make a decent media player or WiFi browser but it won't act as a phone.
Edit0: I've often found much better (repairable, long lasting) products for myself by looking in the enterprise/ fleet catalog. My oft-mentioned HP Elite X360 is another example of a device targeted to the corporate market and as a result, enables easy replacement of the SSD and battery.
I also didn't claim to know what is good for consumers. It should be obvious that given the choice between thick and heavy or thin and light consumer sales have favored thin and light for the past decade. That's not me dictating what is good, it's just me paying attention to the smartphone market for more than ten minutes.
I am happy for you that you find phones and laptops that last you a long time. Bully for you. But you are not the bulk of the smartphone or laptop market. You represent a tiny portion of both markets. I know this because you have to hunt down phones and laptops with replaceable batteries while pretty much everything on sale at BestBuy is all glued together. Buy the shit that you want but don't pretend that you represent some silent majority quietly yearning to replace batteries in their phones and swap hard drives in their laptops.

And since it is a Samsung device, by the time you get ready to change the battery, Samsung more than likely won’t be updating the operating system.
The $399 iPhone SE has a better processor, camera, finger print sensor and given Apple’s history, will probably get operating system updates for five years.
You could get the battery replaced, and have an updated operating system for years and still be at slightly less than $499.
And you don’t save any money. The $399 iPhone SE with a battery replacement will be cheaper, smaller, lighter, supported, and faster.
you don't know the support cycle of this commercial device
Has any Samsung device ever had six years of upgrades like the original SE/6S?
often options such as LineageOS become available for such devices.
Yeah that’s something most consumers are going to do. As opposed to just going to settings and click upgrade.
So tell me again what is the advantage of the phone again? It’s not price, longevity, weight, size, or performance.
The phone you linked to is worse in every objective measure.
The fact is that even the best Android phones also don’t have a replaceable battery. Are all the manufacturers under the same delusion that consumers don’t care about replaceable batteries?
For once, just once, I'd like to hear you say something even slightly bad about Apple. Come on, just once?
The argument is that the market doesn’t care.
If the market cared about replaceable batteries why are all phone manufacturers creating high end phones with none replaceable batteries? It’s not just Apple it’s the entire industry.
Engineering is about tradeoffs. The phone you linked to proves exactly that - the phone is bulkier and heavier than the state of the art phones from Samsung
Isn't that kind of facial detection done in software? How can it be `heavier' or `thicker' if it's software?
> heavier, thicker, face detection that is not secure,
Is it maybe a way of saying more computationally intense or more layers in a neural network? It could be a non-native speaker, but to me those adjectives only really apply to physical things. I'm not sure.
BTW iPhones are really heavier.

It was my Plex server until earlier this year. It’s thick, it weighs over six pounds, it runs hot and even with a new battery it wouldn’t last more than a couple of hours.
What’s the point?
That it was still useful to you until it was ten years old, and it should be the same for phones.
Apple just released a bug fix update for the 2011 iPhone 4s, June of last year. How many Android phones got security patch/bug fix releases for a 9 year old phone? Yes you can still get the battery replaced for it.
Have you tried using a ten year old Android phone?
