iPhone 6 Motion Calibration Always Using Location Services

just received my iphone6 and is updated to ios8.

IVe noticed that the location services was constantly on so went through each item which was enabled for location sharing and disabled one by one. I discovered that under Privacy > Location Services > System Services > Motion calibration was purple. As soon as I disabled it location sharing icon switched off. As soon as i enabled it it came back on again and the purple icon showed up next to motion calibration meaning it was in use.

So my question....what is motion calibration and why is it constantly using location services??

thanks

iPhone 6, iOS 8

WRONG. It is explained very clearly what a purple arrow means, and it does not mean it is actively being used. Read what it says at the bottom of the Location Services setting:

"Recently Used" is NOT the same as "Actively being used."

Yes...that drains the battery.

Also wrong. There are anywhere from a dozen to hundreds of apps and functions on your phone (depending on how many apps you have installed) that consume battery. You are focusing on the least likely cause of your battery problem.

The Location Services arrow on my phone's status bar is always displayed, and going to location services I see a total of 24 arrows displayed, and 10 of them are purple (one is a geofence, which DOES continuously actively use Location Services). If Location Services was a major battery drain my battery life would be 15 minutes. Instead, I only really need to charge every 2 - 3 days; if I charge overnight by the end of the day my remaining battery is typically 70%. And I'm a heavy user, with over 250 apps installed.

By paying attention only to one arrow in Location Services you are essentially denying yourself the opportunity to fix your battery issue.

Try this: Settings -> General -> Reset -> Reset Location & Privacy

I seem to have made a little bit of progress with this issue concerning Motion Calibration and Location Services.

Things I tried (and didn't work):

Reset Network Settings
Power cycle (duh!)
Soft reset (holding sleep and home buttons for a few seconds)
Complete wipe and restore

What seemed to work was something very simple - I turned off Motion Calibration and this removed the Location icon from the home screen. I turned it back on and the Location icon came right back. I figured this was just the (iPhone) life condition and put my iPhone down for a bit (about what it takes to make a cup of coffee). When I got back, I picked the phone back up and noticed that the Location icon was gone! I went back to check if Motion Calibration was enabled and it was.

What I've noticed since then was that the icon does pop up every now and then (perhaps when calibrating motion?) but clears itself after a few minutes. Perhaps this is how it was always supposed to function but the icon never cleared itself; either that or Motion Calibration truly didn't shut off. I will attest that regardless of everything else I did, I never thought of just "turning it off and on again" for Motion Calibration (i.e., disabling and re-enabling Motion Calibration).

That "works" just because when you do that (reset location & privacy) what it does is to turn off the icon but locations are still working.

Every night before I go to bed, I close all apps and put the iPhone down (home button face down) all night long, it doesn't work.

When you turn off the iPhone and turn it on, you'll see that MC works for 10 seconds ~ but after a while it comes back to be there forever haha.

Just turn 'locations services' off and on again fixed the problem for me.

Yesssss, Just turn 'locations services' off and on again. (ON LTE or 3G not WIFI)

Jan 18, 2015 9:02 PM in response to STiCKeRz

It worked for me as well.. Been using for only 15 minutes still. Can poeppe confirm if it sticks for longer?

Also, I did as u said on 3G. Any reasons it won't work with wifi on?

I can confirm that on WIFI it changes to "always on" after an hour or so, i will check on LTE or 3G.

So guys, i think i found the solution. I uninstalled Health mate. This was the only "health app" that i was using and it seems that it was causing the problem from the start.
