When I want to use my babylon webpage on phone, the webpage can be opened on Android but not on iphone.  
I think this maybe related to memory and gpu.  
So how to know the memory and gpu cost of babylon webpage?

First of all I would say is it on all browsers on the IPhone or only a specific browser.

But that wont solve your case of knowing the memory usage.  
Maybe this link helps you to have that insight.

For the memory you may use `performance.memory` like here - [https://playground.babylonjs.com/#938RNX#29](https://playground.babylonjs.com/#938RNX#29)  
The problem with iPnohes are often related to big texture sizes. It shouldn’t be more than 2048\*2048, smaller is better.
