OPPO A5 2020 & OPPO A9 2020 viSerMark Battery Life review – March 2020

OPPO A5 2020* & OPPO A9 2020* have recently landed in our lab and our team has been very excited to go through the ViserMark battery life scoring testing protocol on those two products.


A5 & A9 2020 target a very competitive market segment (200 -250 Euros in Europe) and OPPO has very high expectations of them as their technical specification should perfectly match customer's expectations of this product range.


First of all,  A5 & A9 are powered by a mid-range Snapdragon 665 chipset which is offering good performance and an overall balanced user experience. This interesting configuration is completed with an HD+ screen and a massive 5000 mAh battery to maintain good performance for a longer period of time. The main difference between A5 & A9 2020 is on the camera side we expect both products to offer similar good battery life.


This is what our battery life measurement protocol has indeed confirmed. Our scenario which is regularly stimulating the devices with a mix of standard usage has been steadily running for more than 2.5 days.   A total of 4 products have been tested and they all performed our protocol during the almost exactly same total duration, which is very impressive and shows how much the overall products are very well optimised.


Our real day-life simulation is covering some long standby (idle) time slots to verify how much power is drained overnight. Idle performance achieved by OPPO A5 and the OPPO A9 2020 is once more, excellent with an average of 1.5% of battery drained over 8 hours. They will be powered to wake you up in the morning and will be ready for a new intensive day.


If you are a heavy user, whatever the main usage of your Smartphone, the OPPO A5 and the OPPO A9 2020 will deliver a very comfortable battery lifetime. Both products are able to follow you during more than 15 hours of streaming over WiFi or 4G when network signal conditions are good. Only intensive gamers will have to charge their device after one day.


OPPO A5 and OPPO A9 2020 have achieved one of the best battery life scores of 2019 products that SmartViser has been testing. Of course, they have a high-capacity battery but they are undoubtedly using each mAh with the best care.
