Today we live our lives through our mobile devices – smartphones, laptops, tablets: we are said to touch our phones at least 150 times a day. Our ability to order a taxi, food or a holiday at the touch of a button or swipe of a screen, wherever we are and at whatever time of day, is the norm. However, all of this is dependent on power and as consumers we are constantly in pursuit of power to remain fully charged. Battery life is a modern-day preoccupation. Research conducted by OnePoll and commissioned by Chargifi suggests that over half of Brits (52%) suffer from battery anxiety at least once a week.
