android memory, VRAM max usage?

Hi, I'm making a mobile Game on Android/iOS at the moment.

Let say that I wanted to aim at XperiaPlay and IPhone4

I would like to know on what would be consider average to [high but acceptable] range of RAM usage.

Thank you for any help in advance.

Looking at Stats, VRAM usage is at 2.3 to 22.2MB Used Texture 6-19.7MB.

I'll optimize these later.
