  • Setting Time Zone Feature Claimed To Be Culprit For iPhone 4S Battery Draining Issues

    If you are one of the many people that have upgraded to the iPhone 4S, you may have been experiencing some issues with your battery. Since the release of the iPhone 4S, many users have been complaining and trying to look for a way to resolve the issue while others have contemplated switching back to an older iOS device until Apple resolves the issue. It appears that a fix has been found though, all you have to do is: turn your “Setting Time Zone” switch to OFF in the Settings > Location Services > System Services (at the bottom of the page).

    What has been noticed by many is that when you switch this feature OFF, the standby time has gone up significantly. After testing this on an iPhone 4S, the new iPhone only lost 5% of its total battery life. The tip originally stems from Oliver Haslam, who noted that the bug likely lives inside iOS 5 and not necessarily within the iPhone 4S hardware. The “Setting Time Zone” ends up tracking constantly instead of periodically, causing the battery time to be severely cut down. According to Haslam, the folks over at iDownloadblog ran some tests as well and saw the same result:

    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.
    The only downside to switching the Setting Time Zone function off is the automatic resetting of your time if you end up crossing the barrier into a different time zone. Changing the setting is a small sacrifice to make for convenience in terms of battery life.

    If you have tried it already, what has your experience been with it so far? If you haven’t give it a shot, come back, and let us know afterward!

      Agree, I'm also on iOS5 with iP4 and seeing the battery drain faster since the update, probably this will help, I just checked it and the mark was blue meaning it was active, I just turned the option off.

Not if you value battery life and overall usability! For the love of god!...Don't do it! You have a sweet thing going with the iPhone.
      Actually, most of the advices you get from the are senseless, if you use an iPhone and disable all the good features on it, you just may as well buy a plain and cheap phone and that it is.

I think turning off location settings for each app when ever possible will be a huge help, as using my TomTom app smashes my battery.
      GPS app as TomTom are battery hungry and you cannot use them for a longer unless plugged it to a car charger or similar device.

      I also heard and there is a youtube video claiming that you need to turn of the calendar widget in notification centre, and this has apparently worked for a lot of people. Allegedly the calendar widget polls for new calendar events 1000+ times and hour and this kills battery life.

      I have switched this off as well and can not fully comment on if there has been any improvement but it still looks like battery life is poor.

      still broked....

      My battery improved a whole lot when I turned off location based reminders. That application has to be constantly refreshing my location in order to remind me at the right location. That was killing my battery..

      I don't have the crazy battery drain some have talked about, I notice 15-20% more battery drain with the same daily usage than my ip4. I flipped the time zone setting last night and will be trying it out today. So far battery actually seems worse! Down to 88% and all I have done is 4-5 text messages, one 2minute phone call and checked my email pretty much. Sigh.

      I'm not sure if I'm having issues or not I get about 1:20 usage and I'm down to 80% mostly 3G web browsing on ip4. Is that normal.?

      I found this on Day 2 after launch. I turned off a bunch of the system location settings. Still drains faster than my husbands 4 with similiar usage pattern. Only thing that helps is disabling SIRI. This is unacceptable. I should not have to turn off the features that attracted me to buy the phone in the first place. Apple really dropped the ball this time. I don't think I'd be as upset if they hadnt claimed such better battery performance in the first place. Just wrong. If no fix by 30 day mark I'm returning it for a 4

      The genius pulled up the diagnostics.
      2.5 hours of use with 26% battery remaining.
      13 hours of standby.

      Here's the thing
      My last charge was last night. I disconnected around 3am. At 1050am I was at 98% with no use. Then as the genius started playing with it it lost 9% is under 10 minutes and nearly 1% every minute.

      He took the phone disappeared to the back for over 10 minutes. Came back with a replacement and a recommendation not to use location services unless necessary. That is what the memo circulating from corporate said.

      The replacement phone is performing the same.

      Original c39
      Replacement c38

      I Asked for a sim key, took out my jailbroken ip4 and put the sim into it.

      Genius: well you properly get better battery life on the ip4s than on a jailbroken phone.

      I nicely asked, better than the 4s?

      this has helped some but not much. my ip4 battery was so much better than the 4s'.

      It's so sad that the ip4 gets better battery life jailbroken with full hacks on iOS5 then the ip4s no jailbreak does

      Not really, since installing iOS5 on a factory unlocked and jailbroken iPhone 4, battery life has decreased a lot.

      My iPhone 4 OS 5.0 jailbroken died this morning after 6 hours with minimal use. I've turned off location based tracking with several apps to see if it's helps. I feel like my phone isn't going to sleep and it tends to run hot while sitting in my pocket unused. Something is keeping it awake, whether it is from the location services or something else, I don't know.

      - passcode lock- wifi (when not at a hotspot)
      - brightness (keep it low as possible)
      - photo stream
      - Bluetooth
      - Equalizer

      I told them I bought the new iPhone 4s to use these features and that I didn't have this issue on my other devices running 4.3.3.
      I'm happy to learn a solution has been found, hopefully this will be fixed with an update. Funny how Apple couldn't figure this out given they created iOS 5.
      Oddly enough my clock was 3 hours fast as of yesterday on my devices.
      Passcode lock? Whyu us that battery drainer.

      sigh, its still bad, maybe a tad bit better, but its still bad.

      Not sure that will help everyone but here is my story. I've had the exact opposite issue. I have both the 4S and 4. Using iOS 5 on both (updated the 4 with iOS 5), used a backup on the 4 and set up the 4S as a new device without a backup. What did I notice?The 4 battery would drain from 100% to about 20-30% in less than one day. My 4S ran four days (3 on standby and about six hours of total use). This was with location services and 3G on the entire time and using Wifi intermittently. Those of you having battery issues who used a backup after upgrading to iOS 5 might want to try and restore your device and set it up as a new device without a backup and see what happens.

      iPod Touch 4g + iOS 5.0

      Not using an iPhone(4 or 4s),
      not seeing any excessive battery drain,

      BUT I'm definitely seeing some differences in time setting with 5.0.

      The iPod (presumably iPhones too) has a rather lame internal clock,
      and it drifts by about 1 second per day (+ .89s or so).

      on iOS4 it syncs time with iTunes, but intermittently and semi-randomly
      so that I find I need to manually sync (e.g. with ntpdate) every few days to keep it in line.

      on iOS5... I have never seen it drift more than 1s off.
      Something is definitely synching, and synching much more often than before.
      And I can't find any user-interface or plist setting to control this behavior.

      Not a problem for me, but I guess if there were a 3G radio waking up and hitting up time servers
      it would be a serious power drain. Possibly the "auto-set time zone" makes it even more hyperactive than default.
