The iPhone 5S didn't bring a lot of new features, as you'd expect from an S upgrade. But like always, Apple did introduce cutting edge silicon that powers the phone. This time, along with the A7 chipset, we got the M7 motion tracking chipset as well. As the name suggests, this dedicated chipset is there to track the phone's motion which can then be used in a variety of different apps such as steps counter. But if this redditor's post is to be believed, your iPhone 5S maybe tracking your motion even when it's powered off.

Doubt it. If that was true they would've marketed the living thing out of it in their initial presentation.

If it is true, then Apple has once again given me that warm fuzzy feeling I love so much.

Devices equipped with lithium batteries are shut down and charged up to very conservative levels so they will at least live through a thousand charging cycles. If the consumption is low enough, this motion tracking thing could very well run a few hours off the battery remainders...

This.

The GPS or w/e tracking sensor is running of the remaining charge, perhaps at a reduced sampling rate (e.g. minutes instead of second(s)).

Now, lets see if the test is repeatable with other iphone 5s (why not other models) and if other manufacturers are not doing the same also

Maybe this tracking app just "tapped" into the "features" they didn't what us to know about (cause hard to believe no one ever noticed before - step counting apps and motion sensors have been around long enough).

Yup, the on-screen battery meters lie to you. Batteries are not technically at 100% or 0% just because the display tells you. They place limits to extend the battery life.

It wont use the GPS thats for sure, accelerometers do not require much power to operate. I guess the itty bitty chip has access to the flash with a dedicated section that it writes to. Not sure what good this is though. Outside a pedometer, it probably wont do anything. If your riding in a car, it probably wont be able to keep any sort of idea of where you are, just knows that you went that way. Polling would also play a bigger part. If you want a pedometer like functionality, it would need a fast interval probably in the .1 second range. Odd, but leave it to apple to add something like this. Hope it turns out to be something cool though.

useful for when little jimmy gets lost in a forest.. or recording the movements 100% of the time of 1 billion people.

whatever

It's possible that the chip can run on a super low power setting, which can last on 1% of the phone's battery for a day or two. Perhaps there is also some sort of very tiny induction generator that absorbs kinetic energy from walking, and turns that small current into usable power for the tracking chip, keeping it going even when the phone is off. Of course, a certain quantity of memory would also have to be powered in order for it to be able to write to some memory.

Apart from an app knowing what you do (running/walking) and where you are, I don't see the point of this, unless oh wait... they want to know where you are of-course.

I wouldn't dream of carrying a phone that didn't have a removable battery.

have you noticed in the last 3 years how many phones now have integrated batteries ?

Saves up on space if you don't have to design sturdy yet simple mechanisms of holding the battery and the rear cover down.
