If you are sufficiently concerned, why not mod the phone to add a physical battery disconnect? Would this not provide 100% protection?

If you are concerned enough, but a phone with physical switches

Or at least phone with a removable battery

I know I will never buy a phone without a 3.5 audio jack

That last sentence surprises me a bit. What does a 3.5 audio jack have to with any of this?

[catlikesshrimp]

Manufacturers are always trying to push features that are more profitable to them. As expected.

Non-removable batteries is the new standard because of that. (Also stream lining) Which is bad for security (the point of the article)

I don't use bluetooth because it is not reliable enough for me, because I don't like charging another device and, less importantly, because in the past it has been exploited to hack devices. The audio jack is the one port I prefer never to part with.

What if there's a capacitor inside the phone that has enough electricity inside to let the phone ping cell towers?

Depending on your occupation it can have very serious consequences.

Even better: practice defense in depth and do both.

Better still, just leave it in a drawer.
