iPhone draining / running out of battery / power

------ Update ------  Looks like the latest build of IOS for the iphone now fixed this problem ------ Finish update ------ There is an issue for iphone's running version 5 software on them, that drains the battery power of the iphone Currently the software is leaving the location tracking services running in the background constantly and draining your battery To stop this * Click on "Settings" * Click on "Services" * Scroll to the bottom and select "System Services" * Un-tick "Settings Time Zone" and turn if off (see pic) Hopefully Apple should fix this in version 5.1 With this disabled if you travel into a different time zone you will have to manually change the date and time / time zone on your phone
