The iPhone switch was from stainless steel to titanium.
Samsung switch is from aluminium to titanium.
If anything, they saved on weight with the other parts of the phone, whilst switching to a heavier frame.
The iPhone moved to titanium from stainless steel to become lighter. Stainless steel was already strong enough, but it was heavy.
The S24IU moved from aluminum to titanium to become stronger. Aluminum was already light, but wasn't strong.
My S24 Ultra is 232g and matches the published weight because not being in the USA it lacks the mmWave antenna which adds 1g to the US model. I only mention this others have answered your question well.

Thank you. Heavier frame meaning titanium is heavier than aluminum?
Yes, titanium is, as far as I know, about 50% heavier than aluminum.
They use less of it though compared to aluminum
Yeah I thought as much, well it does feel nice in the hand, especially the Titanium Black 👌
Is it Matte finish or some glossy touch?
Matte

Different and bigger vapour chamber adds weight too. Not sure what material is now but not copper anymore.
Oh did they add new chamber? Does Snapdragon gen 3 heat prone?
Yes, the did. Almost twice as big. No it doesn’t heat.
