It makes absolutely zero sense to have these thin lightweight phones and then add a thick heavy case around it
I have have a glass back phone without case. Dropped once and cracked. Slippery as hell too! But I flat out refuse to use a case. (disclaimer: it’s my workphone, so I tend to not care so much)
The current phone I have has 70x135mm dimensions and 5” screen.
I would accept up to 75x145 but not more.
Closest phone I found that I might like is the Blackview BV6600 Pro, because it has a big battery and a thermal cam… but it’s also huge, 80x160
There are some thin cases with protruding edges.
The glass back is usually cheap to replace (unless it’s an iPhone). The screen on the other hand is quite expensive. Smartphones are not made to be dropped. The screen can break at any time.
Pixel 5 is not too much bigger than 4 and has 8G memory.
How is the battery?
I see it has one of those useless high density screens that probably draws a lot of battery.
Why are those the requirements? Wireless charging make the backs glass. I have an iPhone SE 2020. I hate the form factor. I just buy the next iPhone but I will try android next once I can relay iMessage to it. I like the smaller phones but I got used to the larger ones. Smaller ones tend to not break though.
The market demands it so they make it. I would suggest the S10 lite. Got an SD card still, good roms, larger than you want but pretty small in my hands. Budget androids are really good. The S7 fits your needs and is probably super cheap right now.
The Pixel 5 actually has a great battery. I can easily go for a few days. They oversized the battery because they wanted people to buy it for its ability to wirelessly charge other phones. I never use that feature, its just a gimmick to me. But I love the battery life. I don’t know what you mean by useless high density screens, I’m getting older and my eyesight is getting worse. The text on the screen is really crisp and easy for me to read. My mother in law also has the Pixel 5 and can read the screen just fine.
Something I tried a few beers ago was using Duplicolor Customwrap to create a very thin, grippy case for a cell phone. 6 layers of the stuff made for a perfect grip.
