iphone is charging but there is no battery charging icon (the lighting like icon in the battery ) on the screen on the top right. I do see the battery icon getting empty and full when its charging but i dont see the lighting icon anymore when i charge it there is also no big charging icon on the lock screen. and there is also no sound when i put. the charger in the device. There are no icons at all that indicate the phone is charging. but my percentage works and the battery icon itself works also. anybody know how to make the battery charging icon work again or what to do ?
