Battery Saver Technologies aims to maintain at least 80% of the battery's original charge capacity after 500 charge cycles. Qualcomm claims Quick Charge 3.0 is up to 4–6 °C cooler, 16% faster and 38% more efficient than Quick Charge 2.0, and that Quick Charge 3.0 with Dual Charge+ is up to 7–8 °C cooler, 27% faster and 45% more efficient than Quick Charge 2.0 with Dual Charge. 134: 55:(SoCs), and by some chargers; both device and charger must support QC, otherwise QC charging is not attained.
