Yes it’s technically possible if you want a heavier, thicker device.

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.

You keep changing the narrative to one that favors your Apple advocacy. You can think of no reason why I might strongly prefer this Samsung over your Apple? Not one? I have seen hundreds of your comments on this site on Apple threads and you never seem interested in seeing the opposing parties point of view. Why? Before you accuse me of the same, know that I have a MBP 2020/16, an iPhone 6s, and other Apple devices. I have recommended Apple to people to whom I felt it would be a fit. I ask you again: can you think of any reasons why I would prefer this particular Samsung?

Your “advocacy” is that a replaceable battery increases the longevity of the device. But how does it increase longevity of a device if it is not going to be supported by the vendor for more than a couple of years instead of six like the original SE? How is it better for the consumer if the phone you linked to is more expensive than the iPhone SE + one battery replacement.

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?

You never answered the question. Not once. You are not even trying. You changed the topic to me 'advocating' for this phone when I, to clarify to you for the third time, was responding to someone who I felt was stating that it's technically impossible to build phones with replaceable batteries.

For once, just once, I'd like to hear you say something even slightly bad about Apple. Come on, just once?

No one was saying that it is impossible to create a phone with a replaceable battery. There have been phones with replaceable batteries for four decades.

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
