PinePhone, PinePhone Pro and Librem 5 should have the best GNU/Linux or postmarketOS support, but their SoCs are not be as fast and energy efficient as other modern phones. You can check my short PinePhone review and there is also some information in this thread. PinePhone’s battery will last a day only if you don’t use the phone much.
for os i have thinked to use ubuntu touch or postmarket os
Note that postmarketOS is not GNU/Linux, since it’s based on Alpine and Ubuntu Touch is GNU/Android or something like that, since it uses the Android kernel. The most popular GNU/Linux distros are Mobian and Manjaro.
