iPhone 6 Motion Calibration Always Using Location Services

I agree with you, but why some people are constantly active localization, even after 1-2 months and others never icon for the calibration of movement even in the first week?

When I do a reset and restore the backup to iCloud I have not always immediately calibration of active movement.

Yestarday when I put the 8.1.1 update icon is back (even in airplane mode)

It is like a bug.

Location Services does not use significant energy. It is a receiver of data, not a transmitter, and it does not use significant CPU cycles. If your phone is getting hot and draining fast it is not because of location services. The Location Services icon is displayed continuously on my iPhone 5S. Yet I get excellent battery life. If you are not getting excellent battery life it is some application or applications that's using energy. That application may be using location services, so turning off location services may rein in the application, but the real problem is the application. And it should be easy to identify the application. You can turn off Location Services for any application. So turn them all off. Then turn them on a few at a time until you find the culprit. If it's applications that use Motion Calibration, that should help narrow it down.

Your snarky post contributes nothing to the discussion and does nothing to help resolve any problem. Believing that Location Services itself is the cause is not going to solve the problem either. It may make you feel smug, but your battery will continue draining until you do some real troubleshooting.

It's much simpler than that ... to know what app uses location just go to "location" and look what app a purple logo to its side.

Just the topics here is about people who constantly have a purple logo next to "Motion calibration". It is a fact, we do not want to know why our phone constantly locates us but why specifically "motion calibration" locates some devices 24/24 and other rarely...

On other forums have some tests and says "Home and Lockscreen" uses a lot more energy when "motion calibration" is active that is not ... This is a sign as the location to a significant impact.

I'm not sure if you're just not very smart or intentionally trying to mislead people. The fact that location services only receives radio data -- which isn't strictly true if you look at how it interacts with the cellular radio, 802.11, and bluetooth stacks, only GPS is passive, but let's pretend your post is actually accurate -- doesn't mean it has to be low power. If location data is being polled from location services frequently, your battery is going to get hammered, and that's exactly what motion calibration appears to be doing to people. We're talking about a service that uses data from 4 different radios in the device. Nobody should be shocked that it can use significant amounts of energy.

The next funny thing about your post is, motion calibration isn't actually something called directly by an application, unless you can point me to the API call and explain how it's implemented. What I see are calls to the core motion framework:

https://developer.apple.com/library/ios/documentation/CoreMotion/Reference/CoreM otion_Reference/index.html#//apple_ref/d…

Calibration itself would then be called as required by the OS. Everything I've seen here leads me to believe that there have been issues on at least some phones, mine included, with the OS calling for calibration excessively, in a manner that is not intended by Apple. You can say it's the fault of a developer for using the core motion framework, but really, if an app calling core motion for CMPedometerData is hammering someone's battery, then it seems if perhaps coremotion isn't behaving as designed on some devices, because the ENTIRE IDEA of this framework and the M7/M8 is to provide a "low cost" (low energy usage) method of accessing this data by keeping apps from polling sensors directly.

I think I might have a solution. I also restored to my iphone 6. What i found was that there was tons of data in the Health app. It went back months even though I only got my new phone a couple days ago. Apparently the restore imported the health data from my 5s. I suspect this is part of the problem, perhaps because the data didn't import properly. What I did was to delete all the health data from the Health app. It was challenging as the app gets very sluggish and unreliable when asking it to show and then delete all data. But I persisted and eventually got it all deleted. I then went back and re-enabled motion calibration and the location icon came on for about 10 seconds then WENT AWAY. It's only been a few minutes but this looks promising!

I deleted all health data, and Motion Calibration is still using Location Services. I restarted my iphone 6 and it is still on. I have done everything I have read here and everywhere and I can't make Motion Calibration to stop using Location Services.

Health app is useless in my iphone 6, even with Motion Calibration on and using Location Services all the time. I walked a couple of miles with my wife and her iPhone 6 Health app shows the correct distance, while my iPhone 6 shows 30% shorter distance. And when I am at home, my iPhone shows I am walking hundreds of yards while I may have walked a few dozen yards.

My wife's iPhone 6 is not using Location Services all the time for Motion Calibration, and it appears to be measuring steps and distance more accurately. It's probably a hardware defect on some iPhones? I have the latest software update.

orate2000, what I've noticed after a couple days after deleting all my health data is that yes, motion calibration is still using location services, but it's not all the time, and way more importantly my battery life has improved enormously!

So I recommend just leaving it on, and don't worry about how often you see the location icon. Just see if your battery life is improved. Also, I expect that in time your health data will be more accurate.

OK I will just leave it on all the time. My wife has had it on ever since we bought the phones, may be that's why her's is more accurate and Motion Calibration is not using location services that much. But I have been playing with all the settings trying to get the most battery life.

Funny thing is, while I have been turning on an off all kinds of settings and she's had them on all the time, battery life is about the same on both phones, and her's is more accurate.

Apple replaced my phone after complaining several times at the genius bar. I set my new iPhone 6 up as new (no backup) and thought the problem would be solved! However, after one day of usage where everything was normal (location services operating as normal) I now have motion calibration AND spotlight suggestions constantly using location services!! Is it possible I had/have two faulty phones? Coincidence?? Opinions please

sarrastro, For a while I also thought I had a faulty iPhone, motion calibration was always using location services. I bought two iPhone 6, one for my wife and one for me. From the beginning I started playing with the settings to maximise battery life, or so I thought, I turned off most of location services, including motion calibration. I started turning the settings back on one by one, and I noticed motion calibration always using location services.

I went to check my wife's phone and motion calibration was using location services very rarely. I tried every suggestion I found online, but nothing stopped motion calibration from using location services. I even called Apple Tech Support and they don't have a clue as to what Motion Calibration is, after putting me on hold several times for long periods of time to go and find out what I was asking, they came back and told me it was normal to work like that and to drain my battery, so turn it off if I didn't want my battery drained. That answer didn't make any sense, they are not the engineers who designed the iPhone nor the software and they obviously don't know.

Someone on this blog suggested to forget about it and leave it on, so I did, but it annoyed me to know the battery was being drained unnecessarily. Since my wife's iPhone was working fine without location services being used all the time, I was convinced my iPhone had a hardware defect. When update 8.1.2 came out I thought may be that would fix the problem, I updated immediately, but nothing changed.

But after a few days, may be two weeks, and before I had the chance to return my iPhone, like you did, motion calibration stopped using location services all the time. Now it is working fine. The location services icon appears a few times a day, but only for 5 or 10 seconds and then it goes away. So my conclusion is that motion calibration needs to acquire enough data from the motion sensors, perhaps two weeks of data, before it can stop using location services all the time. My wife's iPhone was able to acquire enough data long before mine because the first couple of weeks of use I had motion calibration off, while she never played with any of the settings.

So, I don't think you have a second faulty iPhone. Actually, I believe there was nothing wrong with the first iPhone you returned. Like the guys from tech support, I think the genius bar guys don't have a clue about motion calibration, otherwise they wouldn't have replaced your iPhone with another one. My suggestion to you is, let motion calibration acquire the data it needs from location services for as long as it takes, perhaps 2 or 3 weeks, and then it will stop. And another thing, when motion calibration was using location services all the time, the battery drain wasn't much different when I turned motion calibration off. The reality is, iPhone 6 battery doesn't last as long as I would like it to. Even my 6 year old iPhone 3G lasted longer, after 6 years of use. I only get 5 or 6 hours of use in a period of 48 hours, which is why I tried to tweak the settings to see if I could make it last longer. But with everything off or everything on, there is not much difference, I get the same 5 or 6 hours of battery while 48 on standby.

Can be a runway furthermore. For all the people having the problem you have " frequent locations" deactivated?

i just got my iPhone 6 few days back and set it up from a backup of my iphone 5. That too was on iOS 8.1.2.

After setting it up I realised that location is on all the time and like all motion calibration was the culprit.

So after trying everything to no avail, I finally restored my device as new and voila. The issue is gone and motion calibrarion uses location every few mins to start with and m sure it will reduce with time.

so i can confirm that restoring as new helps ...

Yesterday was the 2nd week since I made a restore with no back up, I made a clean installation of latest iOS, MC is still on all day. I'll be patient and will wait to the 3rd week and see what happen.

So I had restored as new just yesterday and spoke too soon I guess.

the MC is on most of the time after a first few hours. But it does seem to turn off intermittently. So I will have to wait a few days to see how it turns out.

Has others seen any change few days after the restore as new?
