While the jury is still out on whether cell phones positively or negatively affect the live music experience, the topic of cell phone battery life remains a relatable struggle. Cell phones are often necessary for a group of friends at a music festival, especially when most events have a dearth of power outlets. Getting lost from your group when your phone’s battery died hours beforehand can ruin your night. Sometimes, putting your phone into airplane mode simply isn’t enough.
Luckily, a solution may be on the horizon. Finnish company Nokia and researchers from the Queen Mary University of London have begun developing a cellphone with a battery powered by sound. The prototype phone’s battery charges when exposed to traffic and street noise, human voices, and most importantly, loud music.
“Being able to keep mobile devices working for longer, or do away with batteries completely by tapping into the stray energy that is all around us is an exciting concept,” said the QMUL engineer Joe Briscoe.
While the final product is likely a few years away, the prototype's initial success heralds an age where dead phones at shows and festivals may no longer be a problem for attendees. It remains to be seen how the technology will change or adapt as development continues, but the prospect could forever evolve the social aspects of live music events. You may never lose your friends again.
