1. Currently looking into OnePlus 8T, Pixel 5a, Oneplus Nord 2CE or other recommendation.
2. (1.5k below)
3. (Doesn't matter, need decent phone with decent camera. maybe 256GB)
4. Been using my OnePlus 5 for almost 5 years already, so I believe anything new is also much better than my current phone already. If need to list then
-preferable good battery
-no overheat issue
-decent camera
-headphone jack can hv or dont hv
-can play game without lagging (even my 5 year old OP5 also can launch genshin impact, so i think doesn't matter)
