Success Metrics


Like most of the high tier devices, the ZenFone 7 is armed with a Qualcomm Snapdragon 865 5G mobile platform. Asus has left behind the IPS display and has bet for a 90Hz full HD OLED display in the ZenFone 7 model. Like the 6 models, the ZenFone 7 is powered by a 5000 mAh battery with a 30W fast charge technology and comes with a homemade customized Android version, the Android 10 ZenUI 7.

Testing Results

Through ViserMark test protocol, the ZenFone 7 battery almost lasted 40 hours, obtaining a 193 ViserMark score. Compared with the average ViserMark score of high tier devices “176.8” the ZenFone 7 is slightly superior, however, most of these devices have 4000 mAh batteries. Meaning we would expect a 5000mAh capacity of the ZenFone 7 to be higher

Test Graphics


To conclude, the ZenFone 7 autonomy is less than expected if we consider its battery capacity and Asus promoted autonomy of two days. Nevertheless, the device is equipped with the latest chipset and a mechanic system to have a top-quality camera.

ViserMark tests are performed with the strictest protocol in a controlled environment to ensure repetition and consistency powered and automated by SmartViser’s test automation solution viSer. The automation test includes a variety of user actions from calls to social media and periods of standby times.
