New device checking rules for flights to/from USA

I see the TSA have brought in new rules for devices, in response to intelligence that terrorists may be trying to pack mobile phones with explosive, so checks before flights can include having to prove the device can power on.

Although fearing the worst and allowing lots of extra time at airports, I have not yet encountered any checks of this sort over and above the usual taking devices out of bags so they can be scanned separately.

From various news articles, there doesn't appear to be any consistent view as to what checks will be carried out.

Can anyone here clarify what they do? Do you have to prove a phone can make a call, or just show it is powered on?

Here is a link to the official announcement from the TSA:

http://www.tsa.gov/press/releases/2014/07/06/enhanced-security-measures-certain-airports-overseas

The text contains the following statement:

"During the security examination, officers may also ask that owners power up some devices, including cell phones. Powerless devices will not be permitted onboard the aircraft."

There is no mention of it having to be capable of making a call, only that you can power it up. The new rules apply only to certain airports that have direct international flights to the USA.
