Some battery-powered products, if not designed properly, may exhibit a phenomenon where the battery fails to charge after being over-discharged. The reason is generally that these products lack a dynamic power path management feature in their charging design. When the battery is depleted and charging begins, the product typically activates certain functions to display charging … Read more
