There’s no easy way to check iPad battery health like iPhone, But I can guarantee it is not broken like under 80% because most of the time my iPad acts as my second monitor and it doesn’t use the battery.
You can check the power usage, 41mins sharp3D usage costs almost 25% of the battery
And good to hear you are now focusing in the right direction, My major complaint is after the last big update, I had to tap the screen twice in two different places to exit the visualization after changing the color, and there’s no way to take a clean screenshot outside the visualization like it was before.
Since Visualization is here my suggestion is to offer a switch to adjust the 3D appearance for 3 levels Max Normal Min, Let me choose if I need more beautiful rendering while modeling, or saving battery and have a smoother performance and mostly lower the heating.
