What do you mean by 'UI?' - The Robin does not use an AMOLED screen so all pixels use the same amount of battery regardless of the colour being used per pixel.
The screen is almost always going to be the biggest drain on a battery, and you can reduce the use of this by:
- Reducing the screen brightness
- Using adaptive brightness where possible
- Changing the screen timeout to a lower volume
I hope this helps
