About 3 years ago Apple Lossless Audio CODEC (ALAC), was involved in a complicated scandal in which she was accused of using linen iOS location monitoring systems without the users knowing. Although a lot of time has passed since then and various "security" systems have been implemented in the operating system of iPhones, it seems that iPhone 5S is able to monitor still our locations, even after its closure. Even if in this case we know about monitoring, when the terminal is open, the worrying thing is that it can monitor the location when theoretically the battery would not be enough.
While traveling abroad, my iPhone cable stopped working so my 5s died completely. I frequently use Argus to track my steps (highly recommended if you have any health bands or accessories) since it takes advantage of the M7 chip built into the phone. Once I got back from my vacation and charged the phone, I was surprised to see that Argus displayed a number of steps for the 4 days that my phone was dead.
The discovery was made by a user whose iPhone 5S it would have been inactive for 4 days after running out of battery, but upon reopening the user realized that a fitness application had monitored all his movements during the time the terminal was closed. Chip M7 performs this monitoring for fitness applications and the only logical explanation presented so far would be that there would be enough energy in the battery to keep the chip active, but without energy for the flash storage medium and the motherboard, the explanation cannot be believed.
Probably no one will provide details too soon about how the said iPhone would have monitored the locations in the moments when it would have been closed, but some researchers will definitely test the theory and if it is true, then we will see a new media scandal .
