Talking about the physical overview, on the top we have a 3.5mm audio jack. The volume rockers and the power button on the right side.

The charger provided is not a fast charger. The device runs on Asus UI v3.0. You get the typical toggles. It is strange that this is a 720p HD screen and not a 1080p screen so that was a surprising thing. The screen quality isn’t really bad, but I noticed that the screen has sort of yellowish tint. The good thing is it is running on Android Nougat 7.0. And it has onscreen controls. It has auto brightness sensor. There is no option for setting color temperature and there are blue light filter controls. The screen is ok and just an average one. As it is running on Mediatek octa-core processor with a GPU of mali T860. The disappointing thing about the sensors is it has all the basic sensors. We have advanced sensors on this device. It is having a 5000mAh battery. And another good thing about the device is that it supports reverse charging. So if you have that adapter you can use this as a power bank. At Rs 15000/- the phone didn’t make any sense. We have many options like redmi note 4, Honor 6X which are much better than this mobile.


Talking about Asus Zenfone 3S Max ZC521TL mobile camera, You have tap to focus. The focusing is good but the shutter speed is sometimes good. But sometimes it lags.  Lighting is good but all shots don't come great. It is a typical Asus cameras. They do an ok job and again they are not the best. It is a mixed product in my opinion.   



ü  Nice design

ü  Performance is ok


û  Average display

û  Average camera

û  Aggressively priced


Asus Zenfone 3S Max ZC521TL felt like a device which is overly priced just in name of battery. This doesn’t mean good. The overall performance of the smartphone is above average. And camera quality is also average. It is available at a price range of Rs 14,999/-
