Not saying it's entirely unrelevant, but when looking at energy consumption by production and by usage of smartphones, the usage basically consumes no energy at all (https://imgur.com/VHpJ5et).

That is probably because batteries can hold a very limited amount of energy and therefore mobile software is developed to use very little electricity.

But on the other hand, less energy efficient chargers wont help this. I just mean it's not the big problem about our smartphones energy consumption.

I see that you're _not_ in the mobile dev industry! Power consumption is the type of thing that is talked about in prerelease mobile software, and removed from the bullet points during release. Nobody optimizes for power consumption at the expense of features, bugs, or developer time.

Sorry, meant co2 emissions, not energy use.

Ahh because these two are decoupled. I am sure smartphone usage contributes a significant portion to CO2 then.
