I’m someone with relatively small hands, plus I want my phone to be on the smaller side since I prefer to use my tablet/computer/tv to watch content. But this trend where many manufacturers tend to keep futures away from smaller phones to drive people to bigger phones is driving me crazy and really makes it hard for me to buy a new phone. I can understand not having everything like maybe a periscope lens or something else that is cost etc. but not to this level. Like take Samsung for example: S24 lacks uwb, 45w, a 1440p display, has a lower amount of ram and storage. Why? Why can’t the s24 have faster charging or uwb? Why is there no 512 version and why does it have to start with 128gb storage? Is it not a flagship? It costs 949€ in my place! Why do I have to give 200€ more to get the s24+ just to get these simple features? I don’t want a bigger phone! Google does the same! No uwb, no thermometer sensor, no telephoto lens. And don’t get me started with all the software features google is keeping for the 8 pro like they don’t have the same processor. Why? Are they cheap? No they are not. I’m just really annoyed by this cause I really don’t want such a big phone.
As Openstars mentions, fitting stuff into a smaller space is much more work and expense than extra material for the body. I’ve watched engineers layout circuit boards for much, much, much less complex stuff and it’s quite a challenge.
Then there’s heat dissipation. Having owned numerous phones, including things like the S4 and S4 Mini, the mini would get hot doing certain tasks. Far less surface area means it will heat up and reduce performance. (Granted this was years ago, that hardware and Android version weren’t exactly efficient).
I’m sure there’s other issues like component selection (and sourcing), how many they expect to sell, etc, etc.
In the end, my money is on projections by marketing/sales/whoever.
