Proxy is using too much data from opening 1 simple website

I am using my own phone as a proxy, I am using an application called iproxy, everything is working fine, but I have a problem:

When using my python selenium to open "What Is my ip address" website through my code, it uses around 50MB of data which is crazy

But when I go and do the same proccess manually without my code it only costs 1-3MB of data usage

Some notes:
I am using this code to config my "Proxy Authentication" proccess which requires username and password: https://stackoverflow.com/a/55582859

I still did not wifi split my proxy, but i am pretty sure this is not the problem
my code is empty it only opens the website, not sure why its using so much data

cant you disable site images as that accounts for most data

disable the auto downloads. also you can talk with the support team of the iproxy.
