Sound was loud and clear, no issues with networks. Reliance Jio SIM worked and I was also able to make calls (VoLTE supported). The home button doubles up as finger print sensor. There are on screen navigation  buttons and a single home dedicated button.

Finger print detection is a bit slow but decent enough. To unlock with finger print you need to press the home button and keep your finger on the sensor.

The Asus Zenfone 3s Max comes with 5000 mAh battery that does an excellent job. You can expect over 2 days of battery life with mixed moderate usage. On a full charge you will get around 7 to 16 hours non-stop moderate to heavy usage.

Asus Zenfone 3s Max Battery Performance (time / battery % drop / estimated battery temperature)

  • Running Benchmark app – 10 minutes / 1% / 34 degree
  • Asphalt 8 game play – 17 minutes / 4% / 41 degree
  • Fhd video playback with full brightness (WiFi /4G on) – 38 minutes / 7% / 37 degrees

The Asus Zenfone 3s Max is a good handset packed with a powerful processor. Camera quality is average and battery performance is excellent. Price is way too high at Rs. 14,999.
