Stingrays and Dirtboxes: how cops can secretly track your phone

That is correct. The phone waits until it has enough power to ensure it won't die during startup because a lot of modern phones (and ultralight laptops) require tapping into battery reserves because the direct pathway from the wall wart to the device was not designed to provide sufficient power to operate at full speed/capacity for more than a brief turbo boost and startup requires more than that.

Battery charges "enough" to that point in less than a minute? I find it hard to believe. 4-5 minutes? Absolutely. 50 seconds?

I suppose the timing depends on if you have one of the anemic iphone ones or a full 2.4+ amp USB charger. Given that charging status is unreliable at low charges and charge tends to "come back" a bit when not actively drawn.

My current phone has an old battery and can go directly from 40% to 70% charge in one refresh cycle (10-30 secs?) after plugging in to my ikea charger.
