Background application to control charging

Hey! I am gonna be buying a quest 2 soon. But I really don't want to deal with charging the battery.

I want to keep the battery between 20%-80% charge (The level of charge in which the least amount of damage to the battery over time is done) So I was thinking about developing a background program that disallows charging at 80% battery and automatically begins charging (If plugged in) at 20%. Or if provoked it would charge back up to 80% from whatever charge it is at. I would also like to be able to disable this feature if I was to bring the quest 2 outside of my home, say to show VR to one of my friends.

This would not only reduce strain on the battery but it would increase the amount of play time available while using an attached battery bank. Though the main goal is to be able to not to have to end my play session early due to battery life or even completely run out of charge while in the middle of a play session. 

I am not familiar with the limitations of quest development.

Would this be something that I could do?
