[Android][URP] Unpredictable FPS Throttling on a device while rendering an empty Terrain

Mobile Rendering

-

Reproduction steps:
1. Open the "New Scene" Scene in the attached "URP Test.zip" project
2. Build and Run to an Android Device
3. Compare the FPS when the project is using URP and when it's using Built-in Pipeline

Expected result: FPS is according to the refresh rate of the mobile device with both URP and Built-in
Actual result: Rendering one terrain or texture causes unpredictable FPS Throttling on a mobile device when switching to URP

Reproduces on: 2019.3.7f1 (URP 7.1.8), 2019.4.11f1 (URP 7.4.3), 2020.1.8f1 (URP 8.1.0), 2020.2.0b5 (URP 10.0.0-preview.26)

Reproducible with: VLNQA00314, Lge Nexus 5X (Nexus 5X), Android 8.0.0, CPU: Snapdragon 808, GPU: Adreno (TM) 418

Notes:
-There's also a "Built-in Test.zip" attached for testing the Built-in Pipeline
-Not reproducible on Windows

    Resolution Note:

    By design: built-in and URP performance is the same. Problem is that low end device overheats and remains in thermal throttling state. Even without the app running device takes several minutes to cool down to a temperature point where full performance is reenabled.
