Does the operator affect the battery?

Question

mobile connection

Hello! I have a question related to the Yota operator ..
Today I bought a SIM card and noticed such a feature .. Is it the same as the iPhone writes in the warning https://yadi.sk/i/PVcFacEWg8GDg or is it all wrong? Because when there was a Beeline operator, then with LTE the battery lost its charge much more slowly than on it .. or so it seems to me.
And can the operator influence the battery charge ..?
And yes, if anyone knows, is it possible to remove the restriction on the modem mode (wifi distribution) on the iPhone?
Thanks in advance for your replies!

Answer 1

Yes it does, above answered why. By the way, with 3G, on the contrary, the better the network, the more it eats, verified by experience.
To remove the restriction on the modem mode, open any page from the connected device and select the desired tariff.
