PowerMaster: The all-in-one intelligent power management app

Your ZenFone 3 Max is built with a bigger battery capacity that lasts through your full work day and beyond. And with the built-in ASUS PowerMaster app, an intelligent suite of power management technologies, your phone can get the optimized performance it deserves, while staying safe at all times.

Double your battery lifespan

All batteries eventually reach the end of their useful life. Good news is, there’s something simple that you can do daily to extend your phone’s battery life, such as avoid overcharging. To increase your battery lifespan, just tap 2x Lifespan then turn on Double battery lifespan. PowerMaster automatically optimizes the charging method to keep the battery in tip-top shape, so your phone can live longer.


Note: The battery lifespan data is based on lab tests, results may vary depending on the actual use.

Reverse charging: Your phone is also your portable power supplier

Your ZenFone 3 Max’s huge battery capacity allows you to charge other digital devices via the built-in Reverse charging feature, making it your portable power supplier. Simply connect an OTG cable to your ZenFone 3 Max, connect the USB cable to the device that you want to charge, plug the other end of the USB cable to the OTG cable, then select a charging option that appears on your ZenFone 3 Max’s screen.



Power-safe technology for better protection

ASUS has developed the exclusive Power-safe technology, which provides extended protection for your system, battery, adapter, and the charging function. The safety check points such as OVP/UVP, TCO, JEITA, and other safety measures protect and optimize your battery’s charging activity. For example, if your phone heats up too much from overcharging, your ZenFone 3 Max automatically shuts off the power. These technologies keep your battery safe under different temperatures.
