If you are an iPhone user, you should know that you can display the remaining battery life. When I bought my iPhone 4, it was not showing the battery percentage and if your iPhone doesn’t show the remaining battery percentage, here’s how to quickly enable it.
Tap on Settings on your iPhone homescreen.
Scroll down and go to General settings.
Under General tap on Usage.
There you’ll see the Battery Percentage option. Just switch it on and it will show battery percentage on your iPhone.
Simple and easy. If you recently switched to iPhone from Blackberry, you can check out our guide to help you transfer contacts to your iPhone.
