ABC news drove around with a cell phone "off" and it was still tracked. "Sources and methods" issues guarantee that the fact it can be tracked will be met with "tin foil conspiracy" allegations in any such thread. I wouldn't bet anything more than a few bucks on the "off is off and on is on" certainly but not much at all. I think there's a pretty good chance there's layers of back doors. I'd would bet that Black Hat/Defcon as already tampered and tested the hypothesis and have published their findings. |

If I was hiding this inside a phone I'd give each phone a unique ID - done.
When the phone is off it remains in a low power listen only state listing for it's "door bell" - a unique combination of bits a few thousand bits long. After being awoken by the door bell the phone reports in and can be interrogated and controlled silently. After the data is transferred the phone goes back to sleep. Alternately it sends a data burst every XX number of minutes/hours/days. The remote control connects in as the system owner and allows a remote user full access to the file system - applications, data like audio, video, and photographs ... everything. |

Just pull the battery out of the phone if you want to be 100% sure that the phone can't ping a tower(s). You can also wrap the phone with several layers of aluminum tin foil. It's cheap and it works.
All of these "RF signal blocking" devices don't completely block RF. They decrease the RF strength. It's called - attenuation and usually measured in decibels (db) on a logarithmic scale. I would suggest to get a "Faraday bag" with at least 50 db of attenuation at 1 GHz. A bag with 20 db rating may also block enough of the RF to disable your phone from communicating if the phone is located relatively far from a nearby tower. It may not provide enough attenuation if the phone is near a tower. |

The "off" button works pretty well for me. No bag required. Unless you're the tinfoil hat-type that believes your phone can still be tracked and is never truly off. If you're using a regular commercially available smartphone in the US, you are most likely being tracked even when the phone is powered off, so long as the battery is in it. This isn't some sort of secret-squirrel stuff, it's for commercial purposes. The phone is not sending anything - it's listening, and sending that information later when you fire it up again. What it is listening to is generally not the cell towers. I would say it's a poorly kept secret, but most people still don't seem to get it. |

The screen goes black and white and the battery will last at least a week without recharging (with moderate use). Charging ports went to crap on all of my previous phones. This phone takes a much wider plug and it's hard to damage. |

Cheap/easy and I’ve heard basically foolproof Faraday cage for larger than a cell phone. Also suitable for long term storage, think dropping your NODs or electronic optics if you’re really paranoid about EMP (yes I know EMPs can’t really screw up small electronics but whatevs):
Take a 30 or 50 call ammo can that’s in good shape with good rubber seal. Cut down a cardboard box and make ‘panels’ to completely line the inside of the box with. Tape them into the box. This creates an electrically decoupled assembly. Drop your phone in and close the lid. Because the cardboard insulates the phone from the actual metal can, waves hit the box and are stopped from traveling further. Nothing can go in or out. If you really wanna go bananas, put the phone in a Faraday pouch first, THEN put it in the ammo can. |

People who claim phones can be tracked while off usually are not very technical and don't understand how they work.
That said, it's not impossible to have this "feature". But to do so, the phone has to communicate with cell towers. To do that the phone has to emit a signal while off to connect to a tower. This is *easily* detectable if one were to check. I have not personally checked, but given the enormous activity in people legitimately scrutinizing every wireless device imaginable out there (look up defcon talks on wireless hacking on youtube) I am going to assume somebody out there would have proof of this if it happens. I have seen nobody, nada, not one single person show a phone emitting RF while turned off. Now, let's say a bad actor with CIA level access to anything were to want to do this. They could push an update to your phone that causes it to appear to shut down when you turn it off. The display turns off, almost everything powers down. Periodically the code would power up the cell tower RF chips and phone home, without appearing to do anything. You're not gonna want to do much or you'll drain the battery which would make it obvious the phone is doing something. You could record audio as well. Issues here would be you have to store the audio temporarily because it's not being streamed in real time, and battery usage over time. You could record audio for a certain period of time, assuming people would turn the phone off immediately before having a private discussion. |

Out of curiosity I did some quick research and found this, which seems to say they are doing exactly what I would suspect to monitor a "turned off phone" (i.e. it's hacked to not really turn off).
It is not explained in the report exactly how this technique worked. But to spy on phones when they are turned off, agencies would usually have to infect the handset with a Trojan that would force it to continue emitting a signal if the phone is in standby mode, unless the battery is removed. In most cases, when you turn your phone off—even if you do not remove the battery—it will stop communicating with nearby cell towers and can be traced only to the location it was in when it was powered down. In 2006, it was reported that the FBI had deployed spyware to infect suspects’ mobile phones and record data even when they were turned off. The NSA may have resorted to a similar method in Iraq, albeit on a much larger scale by infecting thousands of users at one time. Though difficult, the mass targeting of populations with Trojan spyware is possible—and not unheard of. In 2009, for instance, thousands of BlackBerry users in the United Arab Emirates were targeted with spyware that was disguised as a legitimate update. The update drained users’ batteries and was eventually exposed by researchers, who identified that it had apparently been designed by U.S. firm SS8, which sells “lawful interception” tools to help governments conduct surveillance of communications. Note the title of the article - "NSA can track cellphone even when they're turned off!" Most people don't read past the headline. Now the big question is - is your phone compromised? |

If I say the sky is blue (the generally accepted wisdom), and you say the sky is purple with pink polka dots (an off-the-wall assertion), I think it is incumbent on you to provide proof of your outlandish claim. Ditto with claiming "off" means "on." So now we delve into the dark world of conspiracies. Can we agree that just about every adult has a smart phone? And maybe, just maybe, some of those people might have access to RF/EM measuring equipment, and maybe, just maybe, they might just experiment on their phone, and maybe, just maybe, post a video of their "off" smartphone registering EM/RF on a meter? Or is it just such an overarching conspiracy that any videos showing this are squelched before they see the light of day? So which is more likely?: 1) no one has ever experimented on their phone, or that people have and the videos have been squelched, and any and all posts describing such behavior have also been squelched anywhere and everywhere 2) "off" means off https://video.foxnews.com/v/5731183327001/#sp=show-clips |

your phone can not only be tracked while off, the camera and mic can also be activated and monitored remotely while "off". i know for a fact federal and state law enforcement have access to those tools. i am sure bad guys with malware do as well. That said it requires a LOT of paperwork to get such things approved for use. it's not something the gov is going to do unless they are looking at you already. if the battery is in and charged it is never truly "off".
power it off and let it sit for a few days. you will notice the battery has dropped a minor amount while powered off. |

So, yes, you can track a phone while "off" because it's not really off. As for whether you can track a phone without a battery, that is much, much more difficult and you'd have to know a lot about that particular phone for the methods I've heard about to be effective. Battery out, in a Faraday bag, most likely not trackable. Not usable, mind you, but not trackable either. Quote HistoryQuoted:

You shut the phone down and slide it inside a tight golden color wire very fine mesh - cloth like it's so thin. That sits inside a ballistic cloth pouch with a velcro flap. The golden mesh folds over tightly. I've tested it both with meters and in the field with last two generations of Samsung's phones and they're dead when inside.
