From the Youtube description:

If you don't have electricity: Get two batteries and dunk them in the cup of water for 1 or 1 1/2 hours and then link the mobile phone with USB cable to the water! Great improvised technique for those traveling through revolution areas, or maybe just backpacking somewhere and you don't have electricity.

Meh, fixes like this are a dime a dozen.
