Depending on how you use your doppel, battery life will vary. At 180 BPM and maximum intensity, the battery will last for over five hours of continuous use. At a lower BPM and intensity setting the battery will last longer.
The average time with continuous use is around 8-12 hours, and we would recommend charging your doppel overnight. If your doppel is fully charged and hasn't been used much in the week it will still stay charged for around 4 days.
Ensuring doppel is fully charged
doppel has been completely charged when the LED on the charging base turns off.
Important, please note: You should charge your doppel after periods of non-use of more than a few days to ensure maximum battery life. This is because doppel's touch controls use power even when the motor is not spinning. You can charge doppel using the supplied charging base in approximately two hours.
How to find out doppel's battery percentage
To check how much battery your doppel has, using the straps as a guide, tap back and forth across doppel three times and then count the buzzes you feel.
Four beats = 75% - 100%
Three beats = 50% -75%
Two beats = 25% - 50%
One beat = 0% - 25%
