Testing Results

Through the ViserMark test protocol, the 7i battery lasts around 86 hours obtaining a 374 ViserMark score. The average ViserMark score of low tier devices is “221” and the 7i score is much higher than most low tier devices. However, it is important to consider the battery size to make an objective comparison.

To conclude, the Realme 7i autonomy is higher than most devices in its price range, offering 3.5 days of autonomy through the ViserMark Test Protocol. To compare it with other low tier devices, a selection of devices powered by a 3000 mAh battery was conducted expecting them to have scores close to half of the 7i ViserMark score (187).

From this perspective, the Realme 7i performance stands close to other low tier devices like the Samsung J6+ (3300 mAh) (190 Visermark score) or the Huawei P Smart 2019 (3400 mAH) (190 Visermark score).

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.
