The iMapMy apps seem to require a lot of battery power. How can I maximize my iPhone battery life?
GPS requires significant power to operate effectively so you might notice that your iPhone battery drains quicker when using an iMapMy app. Don’t despair. There are a couple ways to extend your battery life while running the app. Decrease the Backlight Timeout from the Settings screen significantly. Enable the app’s screen lock feature (the Padlock icon on the upper left of the Record screen) will also extend your battery life. Note: the iMapMy+ apps include iPod functionality and Voice Feedback options that can further shorten battery life. If you plan to use either of those two features regularly then consider purchasing one of the many iPhone battery extenders available for sale online or at the MapMyMyFitness store at http://www.mapmyfitness.com/shop or your local Apple store.
