Benchmark Performance

The Max Pro M2 has been given a boost in performance over its predecessor thanks to a more powerful mid-range Qualcomm Snapdragon 660 processor and a whopping 6GB RAM. The only other entry-level phone using a 660 processor is Xiaomi's Mi A2.

SunSpider Javascript

SunSpider JavaScript measures the browsing performance of a device when processing JavaScript. It not only takes into consideration the underlying hardware performance, but also assesses how optimized a particular platform is in delivering a high-speed web browsing experience. 

The ZenFone Max Pro M2 was the best performer in this comparison thanks to its speedy processor, 6GB RAM and stock Android OS. Actual browser performance was fast and smooth.


Basemark OS II

Basemark OS II is an all-in-one benchmarking tool that measures overall performance through a comprehensive suite of tests including system, internal and external memory, graphics, web browsing, and CPU consumption.

The ZenFone Max Pro M2 was again the best performer in this benchmark.

3DMark Sling Shot

3DMark Sling Shot is an advanced 3D graphics benchmark that tests the full range of OpenGL ES 3.1 and ES 3.0 API features including multiple render targets, instanced rendering, uniform buffers and transform feedback. The test also includes impressive volumetric lighting and post-processing effects. We're running this benchmark in Unlimited mode, which ignores screen resolutions.

Once again the ZenFone Max Pro M2 showed significant improvement over last year's M1 and was also faster than the Mi A2 thanks to its extra 2GB RAM.


Imaging Performance

The ZenFone Max Pro M2 has a dual rear camera setup comprising of a 12-megapixel f/1.8 primary camera paired with a 5-megapixel depth sensor, which is only used for capturing information for Portrait Mode.

The default camera app is a custom version from ASUS rather than the stock Android one. The camera app has most of the basic features, and even includes a Pro mode, that lets you manually adjust most settings. According to ASUS, the camera app will also be getting a firmware update in mid-February which will add AI camera features (first seen in the ZenFone 5).

Image quality is pretty good, especially for a phone this cheap. Colors and white balance are accurate, and detail retention is good, with fairly low noise or processing. However, the phone does struggle a little in low-light situations, and the auto-focus could be a bit snappier. For those interested, head over here to check how the Max Pro M1 and the Huawei Nova 3i fare.

Battery Life

Our standard battery test for mobile phones has the following parameters:

  • Looping a 720p video with screen brightness and volume at 100%
  • Wi-Fi and Bluetooth connectivity turned on
  • Constant data streaming through email and Twitter

The ZenFone Max Pro M2 has the same size 5,000mAh battery as its predecessor. While its battery life was still great, lasting eleven hours and 13 minutes in our video looping benchmark, it actually fell slightly short of the Max Pro M1. This is presumably due to the Pro M2's larger display and more powerful processor. Still, it's a good showing by the newcomer.

The ZenFone Max Pro M2 supports fast charging, but only up to 10W of power. Due to the sheer size of the battery, it actually takes quite a long time to charge the phone. Using the bundled charger, the Max Pro M2 reached 50% in just over an hour, and took nearly three hours to reach 100% charge.



When I reviewed the Max Pro M1 last year, it narrowly lost out to Huawei's Nova 3i, due to the 3i's more interesting design, better features, and slightly better performance. However, the improvements ASUS has made to the Max Pro M2 change things entirely, and the new attractive Wave Design, larger display, much better performance, same great battery life and stock Android OS, all without an increase in price now makes ASUS the clear leader when it comes to entry-level phones.

The ZenFone Max Pro M2 punches well above its weight, and it looks, feels and handles like a much more expensive device. If you're on a tight budget for your next phone purchase, and you're looking to get the most bang for your buck, right now, there's no better purchase than the Max Pro M2.

At the point of publishing this article (4th January 2019), local online stores have yet to receive sales stock. By 12th January 2019, all authorized online stores have the phone stocked:- LazadaQoo10 and Shopee.
