S25+ vs s26 ?

I wanna buy a samsung phone but i m really scared of heating and battery degradation. My needs are : amazing software experience , browsing and social media and very stable video recording and a good decent 7-8hr SOT of battery life.

I m getting s25+ for 71k inr for 12/256 variant Whereas s25 i m getting for 83k for 12/512 variant. ( 256gb honestly is enough for me )

So my biggest concern is obviously heating ! I m told s26's new 2nm Exynos processor is gonna be very efficient and s26 has a new vapor chamber as well so i m curious how it fairs against larger s25+ . Also i saw a video or s26 and they mentioned its still an 8bit display, which honestly kind of disappointing if its true ?.
