Question 78mb User Assets, 170.39MB .aab Build Size

Hello!

For months I've been dealing with unreasonably large build sizes in my mobile game. It's a fairly small game - Two 2D canvas screens (asset bundle loading, login) and two 3D scenes (main menu, game level.) I've moved every asset referenced in my editor logs/build report into asset bundles, yet the build size is still massive! I'm not sure what I could be missing. Here is my latest report from the editor logs when trying to build an Android bundle:

Build Report
Uncompressed usage by category (Percentages based on user generated assets only):
Textures 66.5 mb 85.3%
Meshes 3.3 mb 4.2%
Animations 1.7 mb 2.2%
Sounds 1.3 mb 1.7%
Shaders 2.0 mb 2.6%
Other Assets 2.8 mb 3.6%
Levels 0.0 kb 0.0%
Scripts 137.4 kb 0.2%
Included DLLs 0.0 kb 0.0%
File headers 136.1 kb 0.2%
Total User Assets 78.0 mb 100.0%
Complete build size 879.7 mb

As you can see, the majority of my assets are in Textures, which occupy only 66.5mb.

I've tried adding scenes to the build one at a time and found:
Asset bundle scene (and Asset bundle screen + login scene) 40-45mb
With addition of Main Menu Scene: 112mb
With addition of Game Scene: 170.39mb

So, each of my 3D scenes are adding 60mb or so to the build! Are there any hidden assets not tracked by the build report that I may be missing?

Thank you so much!

Edit: When I compile JUST the Game Scene the total build size is 113.35MB!

I resolved this issue by disabling static batching, as suggested in: https://answers.unity.com/questions/1352782/why-are-the-levels-editor-log-from-build-size-so-b.html
