While traveling to Portland last month, I had the pleasure of sitting next to an Apple Genius from the Wayne, NJ store – now how lucky was I!
One of the secrets shared that I know you will all find helpful, especially when you are at the beach or away from the office and see that your battery life is getting low, is:
Double click on the Home button – the button at the bottom of your iPhone, in the center. You will then see a row at the bottom of your screen showing applications. These are all the applications that are running in the background, draining your battery. The Mail program is the worst offender. To turn off these applications, hold down the icon until you see the red dash (minus sign) and the icons shake, click on the dash to remove them from the background.
Another power-saver hint, Mail does take up a lot of energy on your phone especially when it is set to continuously check for email. If you go into Settings, Mail, Contacts, Calendar, turn off Fetch New Data.
This should at least give you enough battery life for the day until you are able to recharge.
