I won’t hold my breath on Apple using this. It’d destroy their upsell from 8gb process in one fell swoop.
Apple only do consumer friendly when forced by the EU.
And even then they'll think of the most malicious way to comply:
Forced to change the connector to USB C? Better only give it USB 2.0 speeds on the regular and Plus model.
Forced to allow third party app stores? Better give it as many restrictions and limits as possible. I assume/hope they'll eventually be forced to open up more, but they'll fight it for as long as possible.
There's a video where someone upgrades the memory of an iPhone by cnc'ing the existing memory chip. So basically using a drill to more or less drill the existing chip to get rid of it. Requires crazy precision.
What the fuck? Like its not even bga or some other kind of soldering?

So I guess it was UV epoxied after soldering and he put new epoxy on with the new nand. Or something along those lines but the component is soldered in a typical way. The rotary tool being used to pull out the residual phone glue is excellent and I feel like I learned something useful even though I'm never going to do an iPhone ram upgrade.

They'd have to redesign their SoCs. The memory chips are right next to the SoC with the M chips.
I've never understood why so many manufacturers do that (laptops with 1 slot soldered and 1 slot replaceable) it seems like the worst of both worlds:
It lets you build one motherboard with all possible ram options.
The smallest one has all it ram soldered on. Therefore less time is required in assembling the laptops. All other patients just need the extra ram placed in the dimm slot.
Thanks! Did the trick!
Generally you can upgrade RAM of different capacities, but only the amount of RAM that matches the original will run in dual channel. I've done it in a couple of machines, and it worked fine. the extra RAM should take a small performance hit, but In my case the tradeoff was worth it. I've also upgraded RAM beyond the specified max. Hasn't always worked.
Yeah, I know it can be mismatched sizes, the laptop i'm typing this on has 4gb soldered + a 16gb DIMM. My question was more trying to understand why manufacturers seem to prefer using one of each rather than just making both replaceable, since the hybrid approach makes it only partly upgradeable while taking up as much physical space as if both slots used removable DIMMs. Since it seems like this combines all of the disadvantages of fully replaceable and fully soldered RAM with only half of an advantage, why are there so many laptops which do it?
I could 100% see them offering user replaceable memory, but with a slower max speed than factory installed. Gotta have something to point to when the regulators come a-knockin.
They could always lock in memory limits until you pay. But i don’t think they will anyway coz doing so won’t increase their sales.
If users have the "I can always upgrade later" option, that screws with the purchases of the higher end models "just in case I need it in the future".
Fun fact: You always use it in the future.
