I currently have a 6 year old xiaomi mi 10t pro. Which phone to get next?

Hey guys, so i bought that phone nearly 6 years ago and want to upgrade. My battery life is draining fast and i just think its a good age now to get a newer one.

I would like to get Android again, and preferable an easy transfer from my old one to the new one. Is Xiaomi still good when it comes to price to performance? I bought the mi10 because of that and was quite happy with it.

Is samsung better? I am really out of the Phone market for awhile now and would like some help if possible. 😄 Thanks!
