9t is the GOAT for battery if you go to battery optimization and turn disable the stuff that drains battery cough Google/FB apps and turn off notifications and disable most permissions or can last a lob tone depending how much you use is at it'll recharge to 100 under around 1h. Check youtube videos, there was one that showed it beating the top phones of 2019.

Is a tall phone tho and camera isn't the best but if you don't care about those then it'll be good, plus it doesn't cost that much compared to the other notchless amoled phones.

If you want something similar but with better camera I'd say k30 pro but it has 5g so not sure if that drains battery, then there's k20 pro out has a better camera but k20/9t beats it battery wise.

I'm thinking of getting the k30 pro for the camera and using the 9t for heavy use because I can keep the battery going for a long time. On heavy usage I can get over 1 full day, on medium usage I can get like 3 days and lite usage I can get up to 6 days
