I think I’ve found a solution to battery consumption on Android keyboard. It is not the best but I need you test it to confirm.
Having noticed that while loading the type-c Cable tablet is atacched, screen doesn´t wake every 30 seconds even if it is connected to the keyboard, I have and idea: attach into that slot one OTG adapter and voila! It works!
I tried to put a simple cable (not connected to a charger) and does not work. And does not work. And it does not work either attach a micro-USB in its port.</span>
t’s a bit sloppy but … I do not know is why it works, but that it ought to guess that you know this.
My otg cable is very simple and cheap, this one: http://www.igogo.es/product473786.html
It is something short for our tablet. All you have to do is cut with a cutter the rubber part surrounding the connector.
I hope your opinions and tests.
In my opinion is a kernel related problem but i don´t know enought to do a kernel for this problem, maybe any dev. I didn´t find nothing about in forums as Slatedroid for our SOC 🙁
