In recent years, consumers have stopped replacing their smartphones every year, as the rate of progress in smartphone technology has slowed (and prices have remained relatively high). Polling data indicates that a majority of consumers now wait two to three years – often until their phones die – before they replace them. As phones get older, however, the batteries used to power them get less and less reliable.
Part of the problem comes from the way many people charge their phones. A lithium-ion battery like those in a smartphone is best between 20 and 80 percent of charge. Either running the battery dry, or leaving it plugged in when it is already at 100 percent charge, hurts the longevity of the battery. It will be less able to hold a charge; so when people are out and about, this may lead them to purchase an expensive battery case or pack to carry around with their phone, or to spend time searching for an outlet with which to use a charger.
Sony may have an answer to this problem. The company recently announced that is partnering with adaptive charging startup Qnovo to include its technology in Sony smartphones. According to Sony representatives, the new tech will double the life of the battery in their phones, to around four years.
Jun Makino, Sony mobile’s senior product marketing manager, said:
“People are starting to keep hold of their phones for way more than two years usage, so we’ve been looking at ways to try and prolong the life of the smartphone. We’ve started learning your charging cycles so that our new Xperia X smartphones only complete charging to 100% when they estimate you’re about to start using them, so that the damage caused by maintaining a battery at 100% is negated. Of course, we’d still like it if you bought a new Sony phone, but we realise longevity is a trend and we want to help with battery technology and services on the phone such as the Smart Cleaner and Xperia tips that learn your behaviour and help keep it running like new for longer.”
