Zenfone Max ZC550KL Review – Autonomy of 7 Days

Zenfone Max ZC550KL

Dual-SIM Android 5.0 Marshmallow, Zenfone Max ZC550KL is neither very thin nor extraordinarily powerful, its hardware easily framing the entry-level range. At a closer look, we discover a smartphone carefully optimized for efficient use of battery with large screen running at a not too large resolution, an appropriate amount of 2GB RAM and less demanding chipset. "Max" appellation is obtained by the virtue of a giant battery, which occupies much of the internal volume of the housing.

Discreet and elegant, Zenfone Max comes in a casing fitted together with the front side dominated by Gorilla Glass shield protecting the LCD screen with IPS technology. Like all phones in the series, Zenfone Max includes under the screen a metal ornament with slightly sticky texture.

Having 156x77.5x10.6mm dimensions and less hampered by battery (202 grams), Zenfone Max is the kind of smartphone which you don't forget that you have in your pocket.

Asus Zenfone Max ZC550KL - specifications:

Screen: 5.5", 720x1280pixels (267ppi) IPS LCD, Gorilla Glass 4
Operating System: Android 5.0.2,
Chipset: Qualcomm MSM8916 Snapdragon 410
Memory: 16GB
Card: MicroSD (max. 64GB)
Camera: 13MPcamera with autofocus and LED flash
Front camera: 5megapixel,
Battery: 5000mAh Li-polymer
Dimensions: 156x77.5x10.6mm
Weight: 202grams

The accessories package includes an AC adapter and USB cable or a wired hands-free kit.


Zenfone Max ZC550KL is powered by a Snapdragon 410 chipset produced by Qualcomm, equipped with 4 cores at 1.2GHz and Adreno 306 GPU series configuration is complemented by 2GB of RAM and 16GB internal memory, expandable up to 64GB by attaching a microSD card. The camera can shoot 1080p and get pictures at 13MP resolution and snapshots, at night has available a dual-tone LED flash. The front camera can get pictures at 5MP resolution.

Synthetic tests and user experience

Powered by an entry-level chipset, Zenfone Max ZC550KL achieve results rather mediocre at performance tests, the CPU benefiting more than the graphics acceleration. Thus, the performance demonstrated in 3D acceleration tests are not exactly stellar, core Adreno 306 being good for less sophisticated Android games. Instead, the use of Zen UI interface poses no problems and the experience with common applications for Android is satisfactory.


Very good lighting, its 5.5˝ screen uses IPS technology, providing very pleasant colors and excellent contrast. 720x1280 resolution may seem small for a smartphone with a large screen, but in practice this easily pass unnoticed, sharpness having suffered too much. Unfortunately the glass shield received less expensive oleophobic treatment, fingerprints are easily noticeable even with strong ambient light sources. Controlled ambient brightness sensor is adjusted to a comfortable level in most situations. Unfortunately minimum brightness does not go far enough, phone use in total darkness is slightly strenuous because of this. Probably can correct this issue with a software update that could eventually help to better manage the battery consumption.

Touch interface is accurate, composing messages poses no problems, responding well to commands and keyboard without too many errors of interpretation.

Phone calls, networking

Equipped with two SIM card slots, Zenfone Max ZC550KL can be connected simultaneously to two telephone networks (first 2G/3G/4G and second mode 2G/3G). ZC550KL can receive calls from any network, but once a call has been answered any unused card is disconnected, the user cannot be contacted on the other network, only after you hang up in progress.


Equipped with Android 5.0.2 version and ZenUI interface, the phone keeps little resemblance to the visual appearance of the default operating system supplied by Google. ZenUI addresses Material Design graphic style, but uses a different color palette.


Helped by a very generous 5000mAh battery, Zenfone Max ZC550KL demonstrated enviable qualities in autonomy tests, and won a clear advantage to the usual Android phones. Aided by screen limited in HD and unpretentious quad-core chipset, the new representative of the Zenfone series phones boasts no less than 7 days of autonomy under a regime of normal use, with permanent access to the internet via WiFi or 4G.

The scenario included daily web browsing sessions, using applications like Facebook, Instagram, YouTube and Gmail respectively camera for pictures. In these circumstances, the 5000 mAh battery took 7 days to go up to 10% capacity, resulting in a time of actual use (Screen-Time) eight hours and a half.

Once without autonomy, the phone must be left about 6 hours for full charge at AC adapter, the operation is best planned for the night period.
