One of the most important features of a smartphone is its battery capacity. The battery capacity shows whether this smartphone will support you to use it all day or not. However, like everything else in the world, your smartphone’s battery wears out over time and loses its capacity. If the battery of your smartphone is always low and you need to charge it mostly, then you need to check its battery health. If it is too old or worn out, you should replace it.
