Suggest a phone under 20k

I am looking for a phone under ₹20K. My main priorities are that it should have good battery, display and good UI. I don't click many photos, so camera is not my main concern.

If possible, it should last for 3-4 years and not be very laggy. Right now I am looking at Nothing 3a, but I have seen people here suggesting that it has UFS 2.2, which could affect the life of the phone.

My budget could go up to ₹25K if I am getting a very good phone in accordance with my requirements stated above.
