Battery Performance Testing and Review - September 2020
With a Battery Life of 1.5 Days of Use, the OnePlus 8 Pro end users can very accurately set display experience. As for every Smartphone offering to change refresh rate we have tested with 120 Hz and 60 Hz settings. 120 Hz (adaptative) is the default refresh rate, this is an interesting point as this means that OnePlus is confident in getting here a good trade-off between fluidity and battery life.
OnePlus 8 Pro also allows changing resolution. We have kept the default FHD+ resolution. Indeed when display is set to 120Hz/QHD+ fluidity and browsing/reading experience is excellent but in this case, the Battery Life is highly impacted. With a battery capacity of 4510 mAh, this smartphone is durable by design, with a 120Hz Fluid display and a super-fast Qualcomm® Snapdragon™ 865 and 5G.

Indeed after several generations of device range, OnePlus has now settled himself as a true flagship maker, bringing also its own innovation.
OnePlus was for instance one of the first to introduce higher refresh rate. 120 Hz display is of course available on the latest OnePlus 8 Pro, animated by very smooth Oxygen OS and powerful snapdragon 865. OnePlus has equipped its OnePlus 8 Pro with a 4510 mAh battery. Let’s check if with an impressive spec sheet OnePlus 8 pro can deliver premium battery life.
