At the recent Mobile World Congress, Chinese smartphone maker Meizu demonstrated its new Super mCharge quick-charge technology that fully-charged a 3,000mAh battery in only 20 minutes. (For comparison purposes, this is a touch larger than the iPhone 6s battery, although most Android batteries hold a capacity of 1,800mAh.) It delivered a 60 percent charge in just 10 minutes. This compares favorably to Qualcomm's newly-announced Quick Charge 4.0 technology in their Snapdragon 835 processor, that can provide a five-hour charge in five minutes.
The downside is when that horizon nears, since the Super mCharge won't be available for the market for another one to two years.
