Battery life on smartphones is immensely important, and so is battery charging time. Most smartphone users have probably faced a time when they wished to venture outside but had to wait until their phones charged, which isn't always the fastest task to complete. SoftBank today announced the Arrows A smartphone in Japan that it claims can provide a full day's charge in 10 minutes. The Arrows A has a rapid charge feature that can provide enough juice to survive a day and has optimizations that can extend that time to three days if given more time to fully-charge the 2,600 mAh battery.
The Arrows A doesn't specify how it manages to recharge the battery so much in such a short amount of time. The phone uses the Snapdragon 800 processor, which has a Quick Charge feature designed specifically to accelerate the charging process. While I have noticed that the LG G2, another Snapdragon 800 device, charges very fast, I haven't seen it fast enough to offer a day's worth of battery life that quickly. Perhaps the measurements for what qualifies as "full day" differ at Softbank HQ.
Over the next few years, smartphone buyers can expect their devices to charge faster. Various technologies are being developed to increase battery power through memory management and new lithium-ion batteries that greatly accelerate the ability to charge phones.
