We built Gemini in a Master and companion model - one of the impact of this product structure is that one of the earbuds will drain more battery than the other.
Let's consider the below example to better understand the model.
- Your mobile is paired to Gemini L so it's considered as the Master
- The master will have two main functions
- Get instructions and sounds from the source (here it's your mobile)
- Distribute sounds and instructions to its companion (here it's Gemini R)
As the master has two main role it's normal to drain more battery than the companion products
