IS 'Setting Time Zone' draining your iPhone battery?

31 October 2011

iphone_batteryThere's been complaints about the battery life in the iPhone 4S and it seems that there may be a fix for it.

With users complaining that their iPhones have been dying after a few hours, even with minimal use, it appears that a location-based feature in the phone that detects when you've physically moved to a different time zone and then resets the phone's clock accordingly may be the problem.

The problem seems to be the "Setting Time Zone" feature which is constantly trying to determine the phone's location and bleeding the battery dry.

Oliver Haslam, of iDownloadBlog says: "It appears that iOS 5's GM release introduced a bug that causes the Setting Time Zone function to keep the location tracking circuitry running constantly, draining battery power considerably. Switching it off may mean that your iPhone will no longer set its own time zone when you travel, but that's a small price to pay for having your iPhone last more than 12 hours on a full charge...We have tested this method on 4 different iPhone 4S handsets, including an iPhone 4 and an iPhone 3GS. All have reported drastically improved battery life after switching "Setting Time Zone" off."

Apple have yet to sort this out, so this is definitely worth a shot if your phone isn't up to scratch.

Setting Time Zone is found under Settings/Location Services/System Services.

    Interesting. Mine was on, but the battery life was pretty good. Turned it off for good measure :)

    I have done the same and just turned off those location services. Oddly since the iOS5 update my iPhone 4 (normal one) has had much improved battery life. Previously I got 1.5 days with 3G off yet now am getting 2.5 days with 3G on!? Very odd. Will see if this location service adjustment adds to the battery life.

    Can't you just carry around a large car battery or something to top up the power levels?
