The space cost of doubling the RAM is zero (if higher density RAM chips are available). RAM in modern smartphones is a single chip stacked on top of the CPU, larger RAM models simply have a denser chip.
The power consumption difference isn't zero but the cost of the memory controller and RAM in a smartphone is about 1W so swapping a double density chip in could only increase the consumption by 0.5W at most if naively assuming double power which is a small amount.
In practice, doubling the density of a same volume RAM chip increases power usage by maybe 10-15% so you wouldn't be able to notice it at all in a smartphone.
