Battery backup

My 14 months old nothing phone 2! I'm not a heavy user, most of the time, it's just instagram, youtube and other social media scrolls. I capped battery to charge till 80%. T Is this the actual battery drain of nothing phone 2 or just the battery getting weaker?? One last thing to try is factory reset but I'm away from home, I don't havey pc to backup things!
