I stared at the phone’s battery life readout, where it resolutely read ‘11%’.
Normally that would be a minor concern. But considering that this phone was attached to a rather large bomb, and the anonymous caller had said that any attempt to interfere with the phone would set the bomb off, we assumed that the battery running out would count.
So while the building was evacuated, we desperately searched for a charger for this brand of phone.
One of the kids had one, so we got it, and plugged it in.
And then found out that recharging counted as interference.
