No it doesn't! That's the biggest issue!
15-90 (QC) - 50-60 mins
15-90 (Normal) - 70-75 mins
90-100 (QC) - 20 mins
90-100 (Normal) - 15 mins.
The only positive difference b/w QC and normal I've observed is, QC remains just as fast even if I game or run AnTuTu alongside, while Normal one can also start discharging meanwhile.
