iPhone Tips : Showing Battery Percentage, Turning on Power Saving Mode, and Reviewing Apps that Consume More Power

iPhone Battery Percent

iPhone doesn’t show battery percentage by default. When you buy a new iPhone, you will see battery bar that keeps decreasing as battery discharges. However, the bar doesn’t make it clear how much power is remaining. In such case, battery percentage is very useful, and you can at least have an idea how long it may run before it need another recharge.

Along with checking battery percentage, you can also see what apps are consuming most of the battery, and what app you use the most. It may help you save battery, and make your device run longer.
