The Core battery should last around 4 days on a full charge, depending on a few factors: how often you use it, how long your meditation sessions are, and whether the sessions you’ve been doing involve more intense vibration patterns.
We recommend when you are not using your Core to place it on the charging base. This will ensure the battery is always charged and you can begin meditating without delay.
It can take approximately an hour to fully charge your Core Meditation Trainer from zero, but if you’re eager to meditate and don’t want to wait that long, it should take 15-20 minutes to get you enough juice to complete a session.
