Question Battery preformance: VSync vs Application.targetFrameRate

Hi! I ran a battery performance test today and got very strange results.
The app under test is a simple 2D puzzle game made exclusively with IU.
The test conditions were as follows:

• 20 minutes of continuous application work.
• 50% screen brightness.
• Internet is disconnected and airplane mode is set.
• 2 devices: xiaomi redmi note 3 (worn out battery) and xiaomi redmi note 8

First test: VSync = Every B Blank
Second test: VSync = Dont sync, Application.targetFrameRate = 60

Results:

• VSync off, target framerate = 60:
  • battery at start:
    • redmi 3: 86%
    • redmi 8: 42%
  • battery at the end:
    • redmi 3: 71%
    • redmi 8: 39%
  • spent charge:
    • redmi 3: 15%
    • redmi 8: 3%
  • heat:
    • redmi 3: moderate
    • redmi 8: small
  • fps: ~60 on both devices
• VSync on:
  • battery at start:
    • redmi 3: 67%
    • redmi 8: 39%
  • battery at the end:
    • redmi 3: 56%
    • redmi 8: 36%
  • spent charge:
    • redmi 3: 11%
    • redmi 8: 3%
  • heat:
    • redmi 3: no
    • redmi 8: no
  • fps: ~60 on both devices

As you can see from the test, VSync has proven to be more effective than fps capping.
Why is this happening?
And what recommendations can you give to optimize battery consumption in general?

 

did you find the solution?
