I purchased new battery and replaced it.
But the battery level indicator is not linear.
For example, I rode for 2 hours and battery drain is 16% (100% -> 84%)
I have another 2 hours ride, but battery drain is 1% (3% -> 2%).
Please note, that all settings and sensors still the same in the both cases.
I tried to discharge the device fully and then charge to full, but it didn't help.
May be there are some instructions or system menu for such cases?
