2. Asus Zenfone 3s Max ZC521TL Camera Review:

  • Asus Zenfone 3s Max has 13MP ƒ/2.0 PixelMaster Rear Camera, PDAF, 5p Largan lens, Dual LED Real-tone Flash and has 85° FOV 8MP PixelMaster Front Camera, HDR, Lowlight, and Beautification Modes.
  • Asus Zenfone 3s Max has 52MP Super Resolution Backlight HDR mode, QR reader mode, Low Light mode, Night mode, Selfie mode, Panorama mode, Beautification, and Time-Lapse effect modes andFull-HD video recording.

But I was not satisfied with the Camera of Asus Zenfone 3s Max neither with the Front nor with the Rear. Even I did not like to Click Pictures because the Phone is priced at 15K INR and having this much of low-quality camera is not acceptable. If you need a good camera phone under 15000 budget then forget Asus Zenfone 3s Max. You can go for Moto G5 Plus or Xiaomi Redmi Note 4 or Huawei Honor 6x.

If you are good in photography and know about the ISO, Shutter Speed etc then you can go to manual mode and set the settings accordingly and you may get some awesome shots. But you cannot do anything with Front Camera even the third party applications like Candy Cam etc failed to take the good selfies.

In Zenfone 3s Max Asus has mainly focused on Battery. And yes Asus Zenfone 3s Max is the best battery phone right now on the market. I have used this phone as my secondary phone for some days and it gave me around 3-4 days of battery back-up which includes normal browsing, YouTube and Phone Calls. So on an average, it gives you 2-3 days of battery backup. I have also used 4G and connected it to WiFi and still gave me 2-3 days of 1 full charge. The best feature in this phone is that you can use this phone as your power bank also. Because it has a reverse charging feature also. With the Help of OTG, you can charge your other phones also and this feature helped me a lot in my recent Trip. However, it doesn’t have a fast charging feature and because of that, it takes a lot of time to charge. But is has a great Battery Optimization and also a great battery backup.
