MOTHER's charging combines temperature difference generation and solar power.
However, under certain conditions, consumption may exceed generation, potentially leading to battery depletion:
・A loose band fit reduces temperature difference generation.
・High-frequency and prolonged activity modes result in increased power consumption.
・Frequent app syncs increase power consumption during data transmission.
・If the main unit is covered by clothing, it won't receive sunlight.
In the future, our goal is to enable users to monitor charging levels and promote healthy outdoor activities to maintain charge when it's low.
