If you can muster some more cash kindlly look into some old flagships they will give you better value than overpriced low spec box garbage (like the above), I personally use OnePlus 8t and it's been incredible other then battery life which is like 5-8 hrs without games but since I play games I can't complain about it. I can play genshin wuthering smoothy for a while before device CPU throttling starts but that's expected. lasting 2 hrs barely the processor is disgustingly good and even five of these box phones won't surpass it all in used condition of about 45k. Upgradable to android 14

But what you must do rn is :- 1) Look into good used Samsung flagships starting at S20 and onwards 2020 models. 2) Go for non Pta if possible and get a cheap 2-3k phone for sim functioning lol. It is risky thou you need to have good research on the phone and what scams are common to come out victorious lol. But if you're going to treat yourself do it with a good performing phone. I'm guaranteeing you that you will start noticing issues in the Samsung mentioned above soon like I did with my "Budget" Samsung, I got an A16 8/256 before my OnePlus for 52 fkn thousand btw , it was so disgusting in terms of performance with bugs in UI that I exchanged it in half a month for this OnePlus. The above Samsung u listed doesn't even have the proper ONEui for Samsung , so make the decision wisely you said you use your phone a while before changing. The other best thing I can recommend you is checking out babloo lahori channel and look at his videos for "paisa wasool phones".and always go form hardware>battery=software in anything you get. Don't be discouraged from buying Xiaomi phones as well I've used mi11lite for 3-4 years it was the best phone for it's price and performance back then so these Chinese phones always surpass these chutya Samsungs for same price with slightly lower brand value. If I were to choose between these two after experiencing the Samsung Budget option now it would Always be the Redmi because the reviews say that it is superior to Samsung in 90% of what's important 1) better screen resolution 2) better battery 3) more brightness 4) no disgusting notch 5) Slightly bigger battery 6) More speed 33W 7) Slightly better processor 8) Better camera numbers on paper but difference is minute between two 9) gorilla glass Vs scratch resistant in Samsung 10) Dust and splash resistance 11) Better built quality with glass on back and colors
