The Zenfone Max M2 has excellent battery life and support. The powerful 4000mAh battery is enough to last an entire day and even more, provided you just use the phone for routine tasks (like calling, texting, social media browsing, lightweight gaming, etc.). For heavy usage involving continuous gaming or video streaming, you might see a considerable drop in the battery, but that is true of all phones, and thus, is not an issue. Although it does not have fast charging support, you get a 10W charger with a decent charging speed.
The phone incorporates all the necessary connectivity options like Wi-Fi 802.11, b/g/n, Wi-Fi Direct, Mobile Hotspot, Bluetooth v4.2, micro USB port, dual-SIM, FM Radio, GPS with A-GPS and Glonass, and 2G/3G/4G support. It also has sensors like Ambient Light Sensor, Proximity Sensor, Fingerprint Sensor, Accelerometer, Compass, and Gyroscope.
