Antwoord op "Battery percentage going down but its charging"The tablet or phone needs to rest and cool off. Do NOT charge the battery overnight. Let it rest a few days or at least 24 hours. Then plug in your charger. Do not use the device. Let it charge up to full max again. PATIENCE is a virtue folks. DO NOT use the device. DO NOT charge with device off overnight. WAIT1 A Day, or 2, or 3 then with device off recharge to max capacity.
