The battery SafePal S1 hardware wallet uses is a lithium battery. Assume that a user uses SafePal S1 wallet 10 minutes per day, the device can sustain around 20 days after it’s fully charged.
Since the battery is a lithium one, one of the nature of a lithium battery is that, if you don’t charge it regularly, the battery life would reduce gradually.
