Plug your phone into the car charger to conserve juice while you're driving and using the iPhone 5 for music, calls, navigation or anything else.Step 7: Shut down the vibes
Turn off the "vibrate" setting if you don't need it or aren't in silent mode. Go to Settings > Sound > two vibrate options there.Step 8: Skip the equalizer
Switch off the equalizer for song playlists. Go to Settings > iPod > EQ.Step 9: Plug into the port

Step 10: Try a battery boosting device
Get an add-on battery charger
accessory, such as the RichardSolo 1800 for iPhone or Kensington Battery
