Battery Life
The QMobile Noir Z9 is powered by a non-removable 2000 mAh Li-Po battery. While the capacity might seem modest, the efficient hardware and the power-saving features of the AMOLED display, combined with the optimizations of Android Lollipop, provide acceptable battery life for a device of its kind. It supports up to 345 hours on standby and around 8 hours of talk time on a 3G network, which was standard but could require frequent charging for heavy users.
