Smart phones today are extremely impressive and boast as much power as full fledged desktops of a couple years ago. Phones such as the LG G3, which has a 1440 x 2560 QHD display, pack a much higher resolution display than many current core i series tablets such as the Surface Pro 3. With all the hardware and software advancements that have been made in recent years, battery technology has been the one thing that has remained the same. With all this demanding hardware how could the energy supply not improve much?
Consumers can never truly enjoy their powerful pocket computers as much as they would like to because they always have to be extremely careful to not deplete the charge of their batteries. How could someone truly enjoy their device when while they're consuming media there is always that thought at the forefront of their minds that they should keep watching the upper right corner as well?
In order to sort of remedy this problem manufacturers have opted to simply use larger batteries. However, there are quite a number of things wrong with this solution. Not only does this make the device heavier but it also makes the device bulkier and thus less desirable. Manufacturers knew this would happen and slimmed down the phones by making devices with non removable batteries. The problem with this design is that batteries can go bad either over a period of time or simply just fail quickly for a number of reasons and thanks to the battery being sealed in to unibody designs, consumers can no longer safely and easily replace the batteries of their phones and are then forced to send in the device for repair or buy a new one.
Another problem that manufacturers have created by simply increasing the size of batteries is that devices now take an even longer time to charge. To fix this problem rapid chargers were developed to, as their name suggests, charge batteries rapidly. The problem that this solution produces is that once you start charging a battery too quickly it can result in a reduced life span of the battery. Obviously the solutions that have been put in place by manufacturers are just filled with compromises.
After years of stagnation, battery technology finally seems to be getting the innovation that it has been missing for years. A company called Qnovo has come up with a way to solve two of the problems. They've managed to come up with a way to charge batteries much more quickly and efficiently which results in an increased life span of the battery.
Their fix is achieved by both hardware and software implementations. The software side to the fix is called QNS and the hardware solution is a chip dubbed the QN200. These two work together to measure battery stats such as the amount of charge remaining, recharge history, temperature and cell status and then calculates the amount of power that is allowed in from a source such as a wall outlet in packets. According to Qnovo, this allows them to reduce the time it takes to charge a battery by a whopping 50%! This also increases a battery's lifespan since current isn't just flowing in from the power source constantly.
What is also impressive is that the software can work without the hardware and has been implemented on the Nexus 5 in the video below! Of course this might mean that we won't be looking at the full potential of this technology but hopefully this means that we can get our hands on this software soon. There have been reports that Qnovo has recently pitched there ideas at cell phone manufacturers. Some manufacturers are interested in the whole package while some are interested in just the software portion.
