[HZ_poland]

Guys, 

I have S21ultra, but battery is poor. I am thinking to replace its battery with S24ultra battery because both are 5000amp.

Anyone knows its possible?

Hey there and welcome to the Samsung UK and EU Community Forum

Although the battery capacity may be the same, the dimensions may not be.

As @Iminvti has absolutely advised, get an S24 Ultra as the battery is optimised for the software that comes with it.
