Investigate your iPhone battery life

Every smartphone manufacturer makes the claim that their battery can last for several hours. But how accurate are those promises?

With the new iOS 5 software, you can actually check.

To do so, open the Settings app, go to “General”, and then click on “usage”, which will take you into a new page.

Down the bottom, you’ll see two summaries under the heading of “time since last full charge”, with categories for both usage and standby. There you’ll be able to see how much battery life you’re getting, and determine if your phone is working properly or there’s a problem.
