Success Metrics


OnePlus is known to be first smartphone maker to release a flagship killer. A flagship killer is integrating a full set of premium components, especially the most powerful chipset of the moment. However in order to keep the price below competition manufacturers should compromise on one or several topics: build quality, picture quality, battery capacity, audio performance… OnePlus is not any more a flagship killer. 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. 

Testing Results

With OnePlus 8 pro end users can very accurately set display experience. As for every device offering to change refresh rate we have tested with 120 Hz and 60 Hz setting. 120 Hz (adaptative) is the default refresh rate, this is 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 to change resolution. We have kept default FHD+ resolution. Indeed when display is set to 120Hz/QHD+ fluidity and browsing/reading experience is excellent but in this case battery life is highly impacted.

When set to 60Hz OnePlus 8 pro achieves an interesting result with 49h and a 2 days rating. With such a great display it would be a pity to stick to a lower refresh rate. When switching refresh rate to 120Hz we noticed a difference in battery life but this one is not excessive even if OnePlus explains that 120Hz is not always applied and software adapts rate depending on content to be displayed. When at 120 Hz OnePlus 8 Pro achieves around 39h of execution for a 1.5 days ranking.

Here is below summary of results achieved with 2 different refresh rates:
