4S Location Services always on for Setting Time Zone?

    I've noticed the poor battery performance since getting the 4S, so I was checking Location Services, and noticed the purple arrow by Setting Time Zone, indicating it was currently using location services. Anyone else have this?

    To find it, go to Settings/Location Services then at the very bottom, System Services.

    same here, updated my iphone 4 to ios5 a few days ago, noticed problem this afternoon, i used the maps application this afternoon, don't know if it has anything to do with it. I disabled the location settings for the time zone, then reenabled it, and the purple arrow came back for 2 minutes, and now it has disappeared. but it stayed on for a very long time this afternoon.

    Yes. Mines doing the same and it really hammered the battery. I've turned it off for the moment until someone resolves it.

    I found switching the time zone setting from auto to manual stopped it happening for me.

    but does this actually waste battery life? it would appear that it does because gps is always on...

    I assume setting time zone to manual mean you have to change it when you travel... any other solutions? What if i just turn off "setting time zone" instead of turning off auto time zone.. what is the difference?

    This is just a guess, but the new system service probably tries to detect your time zone via GPS. In ios 4, I think time zone was detected through your cell network.

    So if I turn it off will it still detect via cell tower?

    I don't believe the GPS is always on and have seen no evidence of that in my phone. It appears it comes on periodically to ID location then switches back off. I'm not seeing any battery issues here.

    This has been a problem since the iOS 5 betas. Beta 2 I believe. They resolved it at some point, but its back in GM. Don't know if it is only on the 4S or on all devices, but it was definitely an issue with a 4.

    Mine is turned to "ON" and it's never purple. It's always grey since it's not actually needing to be used.

    It was always purple on my iPhone 4 running iOS 5. I turned it off.

    So at the top of your phone the purple GPS triangle is on all the time? I don't see this on my 4S. Did you update from a beta or something that maybe brought bugs with it? It is odd some see this and others do not.

    this is a fairly well known fix.

    It's certainly massively improved my battery!

    Same here! Get confused and annoying

    It is gonna turn on every 2~3 mins and last for 5 to 15 and more mins ( depends how long u use it). sometimes even long the entire night ( but plugged to power). When I stayed home or in campus building or whatever place, the icon appears periodly. And look at the usage time vs idle time, it's rediculous: half of the time my iPhone is in used even though I leave it alone.

    Once I turn off time zone auto setting, I'll gone.

    I finally find out why my iphone run outta juice that's fast! Its more because GPS using rather than be in a weak signal area I guess!

    iPhone 4 with iOS 5 installed on Three network in Australia.

    What's the purpose of doing this or just a Bug?

    GPS always on by auto setting time zone function

    Or maybe iPhone use the gps signal help to choose a better cell tower#?

    Or just use it for quick launch of Camera (with location tag right?) ? #

    Or just being tracked by friends in Find Friends?? #

    Or just kill ur battery especially after one year warranty but no extra Apple Care Plan? #

    Or just need a backup power station like Air Juice ? ☕
