OPPO Reno Series started in 2019 and the first Reno Smartphone became famous thanks to its unique shark-like fin design which integrated the selfie camera. With the OPPO Reno 4 Series just having been released, OPPO is back to a more conventional front side design now with a selfie camera placed into a small punch on the screens.
The OPPO Reno 4 Series includes three different models, two having integrating displays with higher refresh rates. Even the OPPO Reno 4Z 5G, the entry model of OPPO Reno 4 Series gets a surprisingly good 120Hz refresh rate LCD display. Overall, all 3 models are lightweight, even though integrating a 4000 mAh battery to power their 5G processors.
Intriguingly, the OPPO Reno 4 5G and OPPO Reno 4 Pro 5G are equipped with Qualcomm Snapdragon 765 5G which has been already seen on many Smartphones this year, while OPPO Reno 4Z 5G gets the Mediatek Dimensity 800.

Battery Performance
Introduction
The OPPO Reno 4Z 5G is classed as a ViserMark Mid Tier Smartphone (between 200-499 EURO)
The overall Battery Performance Score is now a global score taking calculations from Battery Life, Power Efficiency and Charging Times.
From the OPPO Reno 4 5G test results, we have given this Smartphone a ViserMark Battery Performance Score of 53. The Battery Performance Label, being nearer 100 indicates that it is one of the better-performing ones and has been ranked in 13th place of the best Battery Performance Smartphones as tested by SmartViser.
Testing Results
BATTERY LIFE - Days of Use
Through the ViserMark test protocol, the OPPO Reno 4Z 5G obtained a Battery Life Score of 2 Days of Use.
The average ViserMark Battery Life score of Mid Tier Smartphones is 1.9 Days of Use. This impressive result positions the OPPO Reno 4Z 5G Middle of the ViserMark Battery Life autonomy ranking.
Testing Results
The OPPO Reno 4 Series includes three different models, two having integrating displays with higher refresh rates. Even the OPPO Reno 4Z 5G, the entry model of OPPO Reno 4 Series gets a surprisingly good 120Hz refresh rate LCD display.
Overall, all 3 models are lightweight, even though integrating a 4000 mAh battery to power their 5G processors. Intriguingly, the OPPO Reno 4 5G and OPPO Reno 4 Pro 5G are equipped with Qualcomm Snapdragon 765 5G which has been already seen on many Smartphones this year, while OPPO Reno4 Z 5G gets the Mediatek Dimensity 800.
After a few days of usage, we soon established that with lightweight and excellent displays, all three Smartphones are wonderfully comfortable to use. Here at ViserMark, our aim is to verify if end users will be satisfied with the battery life and performance of Smartphones. We tested and proved the real difference in terms of battery performance across the three Smartphones from the Reno 4 Series.
On taking delivery of Smartphones in our testing lab that integrate screens with variable refresh rates, our ViserMark scores are calculated by averaging results across the different settings.
All three Smartphones within OPPO Reno 4 Series achieved very similar battery life performance with respectable scores starting from 44 to 53. The OPPO Reno 4 Pro 5G and the OPPO Reno 4Z 5G have been both ranked with over Battery Life of 1.5 Days of Use, with individual Battery Performance Scores of 48 and 44.
The OPPO Reno 4 5G has been ranked with a Battery Life of 2 Days of Use, with a Battery Performance Score of 53. With its 60Hz refresh rate display and the capability to support a Battery Life of 2 Days of Use, it has excellent performance for a combination of 6.4’’ screen/183g body. These results define the OPPO Reno 4 5G Smartphone as the best of the three in the OPPO Reno 4 Series.
There are a number of power-efficient processors, within today's Smartphones, that are able to cope with the growing number of new applications and can support high-resolution displays without compromising battery life.
Power Efficiency is calculated using Battery Life and Battery Capacity. This is expressed in “Leaves" and reflects a rating between 1 being least and 5 being the most power-efficient.
The OPPO Reno 4 5G achieved an overall Power Efficiency Score of 2.
Best Smartphone for Power Efficiency: Ranking #36
Conclusion
To conclude, the OPPO Reno 4 5G Battery Performance Score achieved was 53 which is lower than most Mid Tier devices.
All three Smartphones from the OPPO Reno 4 Series clearly demonstrate their power efficiency through the ViserMark testing protocol. By combining light bodies, 4000 mAh batteries and mid to high-end processors, particularly on wide screens, often causes a compromise in the Battery Life performance.
OPPO succeeded to overcome this challenge by achieving an incredibly good integration of all components to maintain a high level of quality experience relating to Battery Life.
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.
