batteries
In my understanding, theoretically, when an uncharged capacitor is connected directly to a battery of, let''s say, 9 volts, instantly the capacitor will be charged and its voltage will also become 9V. This will happen because there is no resistance between the capacitor and the battery, so the variation of current by time will be infinite.

The lithium ion battery will support that load until it''s almost completely discharged; a bigger concern is discharging the battery so far that it destroys the battery. The ultracap, however, will drop from 3V to 2V and still have almost half the total charged energy still in the capacitor, unavailable to us because of the drop-out voltage of the phone.
