Asus has been manufacturing smartphones for a long time and they have been able to produce some amazing flagships too. They also seem to have captured a significant market share. Asus has launched ASUS ZenFone 3s Max (ZC521TL) as an upgrade to its earlier versions. This time the phone comes with a huge battery life and has some minor design changes. So, let’s see how this smartphone turns out to be in real life.
The phone sports a full metal unibody design. We can’t say that the design is somewhat unique, but then again it’s not traditional too. The device does radiate a distinct vibe of premium-ness, as it boasts its well-built aluminum chassis. The phone doesn’t features with capacitive buttons. Instead, this time Asus has introduces on-screen buttons. The fingerprint scanner has also been provided in the front of the phone, just below the display. One of the best parts about this phone is its screen-to-body-ratio that is kept at 75%. The phone is 8.85mm thick, which again is not that bad. Weighing 175 grams, the phone is not that heavy if you factor in the fact that it packs a huge battery. The phone is available in two color variant i.e. Black and Gold. Talking about the display of the phone, the phone features a 5.2 inches IPS LCD that provides a screen resolution of 720 x 1280 pixels and corresponds to a pixel density of roughly 282 ppi. The 2.5D curved display turns out to be rather bright, and so provides a fantastic sunlight legibility. The viewing angles are fairly excellent too. Considering the fact that the phone offers only an HD display is rather disappointing, as now one can easily find FHD display even in low budget smartphones.
This phone features with a 1.5 GHz Octa-core Cortex-A53 processor that is backed by a Mediatek MT6750 chipset. The processor is capable of providing a decent Android experience. One may not be able to play few heavy apps or games on this phone that smoothly and they might have to go for maximum performance mode to get the desired result. The phone also comes with Mali-T860MP2 GPU that makes sure graphics remain top notch. The phone works on Android version 7.0 i.e. Nougat with the help of Asus’s ZenUI 3.0. A 3GB of RAM is provided in the phone, which we think is decent. The internal memory provided in the phone is 32GB and could be expanded up to 256GB using the hybrid SIM card slot. The phone offers dual SIM support and also supports 4G/LTE networks.
The phone features with a 13 MP primary camera that is supported by a dual-LED (dual-tone) flashlight and autofocus. An 8.0MP front camera has been provided in the front. The images captured by the rear camera are decent, however, the color reproduction seems to be messed up and the images seem to be a little washed out. The images seem to be not that sharp. However, the images are decent enough to be shared on social media. The rear camera failed to take decent images in low light conditions. The front shooter was able to take decent selfies. Overall, the camera of Asus Zenfone 3S Max is plain average. The phone features a loudspeaker which gets loud enough and a 3.5 mm audio jack has also been provided in the phone.
Now talking about the most touted part about the phone i.e. the battery. The phone features with a huge 5000 mAh Li-Po battery. The battery is non-removable and promises stand-by time up to 816 hours on 3G networks and talk time up to 28 hours on 3G networks. When the battery was tested in real time, we found that the battery lasted for a two whole days with moderate to heavy usage. The connectivity options include WiFi Direct, Wi-Fi 802.11 a/b/g/nac, dual-band, Bluetooth version 4.0, Hotspot, A2DP, EDR, A-GPS, GLONASS, BDS, FM radio, microUSB v2.0 and USB On-The-Go. The phone comes with sensors such as Fingerprint (front-mounted), accelerometer, gyro, proximity and compass.
