Smartphone without a battery (2022)

It is criminal that supercomputers in our pockets have expiration dates.

Even cheapest phone these days is hundreds times more powerful than PS2, has better camera on par or better with most feature phones back in the days and cellular/wifi. They can be used for detection, automation or just plain fun/gaming.

But no, you can't install Linux to overcome bloated, insecure abandonware (old Androids, iOS). Built-in, hot pillow of a battery that is pain in the ass to remove and even then it can't work without it.

I understand. I got a Linux phone & its remarkably decent - its called Jolla

I need to know if this is running e-banking a.k.a. "we are secure, yet is that you that made this payment" apps?
