With the iPhone 4S and iOS 5′s reported battery woes, it’s no wonder then that you’ve keeping a close eye on the battery meter. The 5.0.1 update that should address these power zapping issues is still 2-3 weeks away from general release. In the meantime though, you can rely on Philips’ BatterySense iDevice app. Like many battery monitors for iOS (Battery Doctor Pro for instance), BatterySense provides users with the estimated hours remaining for talk time, internet use, audio/video playback, gameplay etc. based on the current charge of the device. What’s unique with BatterySense is its “What if?” feature. By dragging the power meter up or down, the app will give recommendations on how to achieve extended usage. So if you wish to add an extra hour to watching videos, it’ll tell you to turn down screen brightness and turn off WiFi. There’s even a “Tips for Better Battery Life” page that gives some nice advice on maximizing your i-juice.
Aside from having one of the cleanest interfaces among battery apps, BatterySense is also a free download. Every iPhone should have one of these utilities installed, and Philips’ is good place to start.
