Qualcomm boasts that it can charge some devices up to 80 percent in 30 minutes or less (?). Power transfer in the latter stages of battery charging is much lower regardless of the charging tech used, hence why Quick Charge can boost your battery to 50 percent or more rather quickly, but will still take over an hour to fully charge your smartphone from zero charge. Devices that are Quick Charge 2.0 compatible can still work with a Quick Charge 3.0 charger but they will charge like they would with a Quick Charge 2.0 charger. A Quick Charge 3.0 compatible device will charge with Quick Charge 1.0 and 2.0, so if you think that you must have a Quick Charge 3.0 charger for a Quick Charge 3.0 device well there’s no need to! Quick Charge 3.0 compatible devices are backward compatible. Fast charging is really what the limits of your device is able to accept.
