For years we've been told not to overcharge our devices or you'll ruin the battery but Nokia doesn't appear to have listened. The Finnish company teamed up with the University of Southampton to show just how quickly 200,000 volts can charge a smartphone.
A Nokia Lumia 925 was hooked up to a transformer that was hit with a simulated lightning bolt in the lab. No one's quite sure how, but the phone managed to make sense of the immense shock and used it to charge the phone in seconds.
Nokia and the Southampton-based scientists say it's an important proof that the more extreme forces in nature can be made good use of.
"This discovery proves that the device can be charged with a current that passes through the air, and is a huge step towards understanding a natural power like lightning and harnessing its energy," said Neil Palmer, one of the scientists behind the experiment.
