Qualcomm has this quick charging technology which makes sure that your phone charges in less time and stays equally efficient. This technology was invented because “Smartphones are dumb when it comes to battery life” and alternative right now is to charge them faster. Though it also means that you will speed up total number of recharge that the battery supports.
Qualcomm rolled out first version of this tech into devices like Lumia 920, Nexus 4, S3 and so on. This version made sure that the phone charges up 40% higher.
Time to get even more faster. They announced on a blog post that Quick Charge 2.0, the next version will ensure that charging happens up to 75 percent faster. So if your phone was taking 7 hours to charge, it might take just 3 hours to do now with this technology.
Extending beyond the device:
Now the version 1.0 has the fast charging available only on the chip and micro USB interface. In version 2.0 this is being extended to even the charger. In the device it is available as Standalone or PMIC Power PMIC power management integrated circuit of Snapdragon™ 800 processors and in charger it will extend to the AC/DC wall charger.
Tablets and Mobiles which will use the Snapdragon 800 Processors will have this technology.
As it is still new, Quick Charge 1.0 and 2.0 will work together. So they are both forward and backward compatible. A 2.0 charger will quick charge 1.0 device while 2.0 device can be charged with 1.0 charger with the speed first generation can charge i.e. 40%
Extending beyond Mobiles:
Quick Charge 2.0 can deliver upto 60 watts of power which means it can even support charging of notebooks. Once this technology starts rolling out globally we might see every other device getting charged by it. All you will need is correct converter.
This technology is expected to roll out by 2014 with all devices. Since one needs to have S800 processor which is like mother of all chip. It carries an SOC a CPU, GPU, DSP, LTE Modem etc. It also supports UltraHD video, high-end 3D gaming, 7.1 surround sound, and up to 55 Megapixel image captures.
