Galaxy A50 or Redmi Note 7

Good evening.

I've spent the past two weeks looking for an adequate replacement for my Honor 6x (starting to get annoyingly slow, especially with a couple of apps open) and everyday I get new ideas. By now I've stepped away from flagship-level phones because I really only use my phone for social media (Reddit, Instagram), YouTube and Netflix and browsing with a pinch of Pokémon Go sprinkled in (and maybe playing on GBA emulators). But I still can't decide on the "right" phone for me.

So what I'm looking for is:

• A good, large screen (is OLED worth the premium?)

• A large battery for when I forget a charger or my Pokémon Go sessions turn out longer and for my general smartphone addiction

• relatively large storage for music, podcasts, videos, maybe pictures

• enough power for a lot of apps open at the same time and for the phone to last me 2-3 years with my current usage patterns

• long and regular updates (or alternatively good custom rom support)

The A50 costs me 242€ in Germany right now, the Note 7 about 50€ less...which should I go for? Or a completely different one?

Thanks in advance!
