My mom tried to track my iPhone 5 using Find My iPhone. My location services were turned on and everything was working properly. Then it said between a certain time that my iPhone was 'offline'. She thinks I manually went and turned it off, making me appear to be offline but I did not do this. It is the second time this has happened since I got the app last year. I need to know why this is happening so that I can explain to her I am not doing it.


Wow, Big Brother is watching! Contrary to popular belief, the iPhone's cell reception is not perfect, and from time to time you can and will "lose cell," and it will appear offline. This can happen when it enters its energy saving mode when asleep, though you should still receive calls. This can really happen any time you're not within a reasonable line of site to a cell tower, or even when switching between towers, and cell frequencies really don't go through wooded areas or mountains or hills all that well, and by that I mean "not at all." It is completely normal for iPhones and cell phones in general to lose cell connectivity when behind a hill from the nearest cell tower. Also, holding the phone wrong can cause it to lose cell, because just holding it will de-attenuate the antenna. And all cell phones have this feature.

Also, the A-GPS system iPhone uses is also not perfect. GPS itself is far from perfect, and really doesn't work all that well (read "not at all") unless you have a line of sight to 3 or more satellites. The 'A' part of A-GPS means "assisted" and you can read about what that means in the link above, and it mitigates some of the issues with GPS.

Using "Find My iPhone" to track family members is a little extreme. I think a more friendly way to have the same functionality is to use Apple's Find My Friends app. Try to talk Mom into using that instead, and then you can track her at the same time, too, quid pro quo.

  • Is there any way to remotely wake up an iphone from its energy saving mode? If my iphone is ever lost it would be nice to find its location, even if it is in an energy-saving state – Nosrac Jan 31 '17 at 18:15

My daughter had this issue as well. She lives alone and relies on me to know where she is if she goes missing. She didn't turn off the setting, but it somehow got turned off. Here is how to turn it back on:

Settings → Privacy → Location Services → scroll all the way to the bottom to Find My iPhone and flip switch on.


You must also go to:

Settings → iCloud → scroll down to Find My iPhone and make sure it is turned ON.
