Try their Tank Mini. Double the pixels, double the battery and still tiny enough: https://www.unihertz.com/products/tank-mini

We have it here in the house, it is a really good phone too.

How is durability? I use a Pixel 4 in https://ghostek.com/products/atomic-slim-pixel-4-series which is very nice because the bumper frame rises above the screen so when you drop it the screen doesn't break. Yet, it's not obnoxiously huge. I love this setup -- except for the Pixel 4 abysmal battery life.

It is obviously a small phone screen size, my wife is using it because she doesn't like to charge phones and didn't wanted a bulky phone either so that was the middle point.

Camera quality is really good. Battery lasts a week, writing stuff is difficult but generic browsing, whatsapp and so on works as intended. She loves the laser range to measure things, has been used often.

In overall the alumminium body gives it a very impressive and neat look, the phone is certainly tough. She is happy.

Then you could even buy a separate digital camera…
