@blazeink that is reference designator C24042 which is a 120PF 10% 25V X7R capacitor in a 0603 package.

@blazeink that board does not have the same capacitors but it does have a 270PF capacitor which you can use. Replacement capacitors with a higher capacitance can be used for as long as the values are never lower than the original. It is C9126 To find it you will need to remove the EMI shield
and then you will find the capacitor in the location as outlined by the blue arrows.

Capacitors like that are typically used to smooth out fluctuations in the power inputs to various components; they're placed very close to whatever part they're protecting.
The pic I posted is from a galaxy s22 ultra the capacitor broken off so am looking a replacement can I get a replacement from another device motherboard like a galaxy note 20 ultra
@blazeink yes you can for as long as it has the same value. I am not sure why you would do that. These capacitors are a "dime a dozen " and really inexpensive. Now, if you have a board laying around that you want to use as a donor board, we will need to know exactly what board you have.
The capacitor is part of your battery circuit so yes, it could be causing the issue.
I have a galaxy s22 donor board
I all so have other samsung boards

The pic I posted is from a galaxy s22 ultra the capacitor broken off so the device boot and show the Samsung logo for some seconds and then goes black and power off. am looking a replacement capacitor. Can I get a replacement from another device motherboard like a galaxy note 20 ultra or any other device

@blazeink what other boards do you have. I do not have the parts list for the S22 board.
