Which flagship phones with replaceable batteries can customers buy?
Samsung was the last major brand in the US to have one, and they made the choice to remove it.

Most of the Kyocera Duraforce line has this ability.
Kyocera's 'flagship' is high-reliability phones in absolute garbage environments.
Samsung's 'flagship' overheats and earns them class-action lawsuits.
Motorola's 'flagship' is a hinged throwback to the 90s.
Apple's 'flagship' is an overpriced piece of vendor lock-in.
Meanwhile my phone takes serious abuse and laughs at it. I've dropped it and watched it go more than 700 feet down the side of a mountain (Chambless Skarn) and BARELY chip the screen protector. Waterproofing still intact. Case barely scratched.
What you consider a flagship phone is a brittle piece of junk in my hands.
At least if it had registered memory there might be an argument that it has some radiation resistance, but no it's plain old LPDDR4x.
Ulefone Armor 29 Ultra has the same MIL-STD-810H conformance with "radiation hardening", 16GB of RAM and a flagship Dimensity 9300+. Just not a removable battery.
Yet it is currently working just fine recording video inside of our rad/AtOx chamber with multiple Strontium-60/Barium-137 sources surrounding it.
"LPDDR4x."
Wrong. LPDDR5 and it has its own error correction features (not as robust as ECC but it's still there.)
That's really neat, but doesn't contradict anything I said.
Also do you perhaps mean Strontium-90? ;)

Their product page lists LPDDR4x: https://www.kyoceramobile.com/rugged-devices/duraforce-pro-3. Unless you have a better source I'm going with the manufacturer on this one.
> it has its own error correction features
Source?
Funny because the Qualcomm sm7450-ab snapdragon 7 gen-1 page lists itself as only supporting LPDDR5.
>also do you mean perhaps Strontium-90?
Nope. Strontium-60. 25 year half life compared to Sr-90's ~29. It's what we like to use in real space-environment testing on the ground. Nasty stuff.
>source?
You can actually probe your hardware and see what sort of ECC is enabled on a Droid phone. In this case, in-line ECC, so that means some of the RAM is actually sacrificed for error correction instead of having a dedicated extra chip (256 bit, 240 of that is data 16 bit is error correction.) What's awesome about that is that enabling ECC is simply a bit flip in firmware and you don't need the extra RAM modules installed - the installed memory can already do it. You don't need the extra hardware.
Those pages contain scarce technical information, it would be silly to say that anything not listed there is explicitly not supported.
Qualcomm's leaked datasheet says it supports lpddr4x: https://www.scribd.com/document/868805341/80-26135-1-AE-SM74...

Strontium-60 doesn't exist. It falls completely off the isotope table (https://inframatterresearchcenter.org/IsotopeTable.html). Strontium-82 has a 25 day half-life.

Care to share how? I wasn't able to find anything on the internet and I'd love to know whether my phone has some limited ECC.
Speaking of which, does anyone want to do a list of "features added to smartphones over the last 10 years" vs "features removed from smartphones over the last 10 years" so we can see just what innovations are at risk?
People generally like small, thin phones, as evidenced by the billions sold. It really isn't much more complicated than that.
Maybe it is more complicated than that
