Android 7.005, Bq5059. sensor accuracy! Charge indicator! How to improve?

Question

Android

Fully charged overnight. 3 hours of charging. Charger for May 2000. 5000 mAh battery
From connected. Turned off. In the morning I turned it on and again 1%. And it lasts for two days!
I start charging in the morning and it reaches 100% in 30 minutes.
Core 3.18.35+
And I also replaced the factory film with shockproof plastic. Top of the screen. Glued.
Now the accuracy of the sensor is terrible. Typing is annoying.
How to reconfigure the sensor or charge indicator?
And generally speaking. Google services turned off and Google Play except Ruth ways in any way?
