The iPhone is one of the most versatile phones on the market. It can run a large number of applications, surf the web, make phone calls, send text messages and emails, and more. All of these things require energy from the battery, effecting how long it will last until it needs a charge. The iPhone has a few ways in which you can check your battery level.
Instructions
1. Look up to the top-right hand corner of the screen. This will show a battery icon that will give a rough estimate of the amount of battery you have remaining. At 20-percent remaining it turns red to let you know you should charge it soon.
2. Turn on the percentage option for the battery. By going into the iPhone settings you can turn on a feature to tell you the exact percentage of charge you have left. Simply tap on the "General" tab, and then tap on the "Usage" tab. You will be brought to a page with a button on the top that says "Battery Percentage" next to it. Turn this button on and the remaining battery percentage should appear next to the battery icon in the top-right corner of the screen.
3. Download a third-party application for the battery. A number of applications have a battery feature. They typically tell you the percentage of remaining charge, but also give you additional information. These applications can tell you how long that charge will last while performing various functions like surfing the web on 3G, on WiFi, playing a game, etc. AppBox is one of the highest-ranked applications with this feature, and it has many additional features for only 99 cents.
