However, the high-resolution panel and fast refresh frequency have a disadvantage. The battery life can vary dramatically, based on how you set up the display. OnePlus also sends the phone with the dynamically set resolution so it can automatically switch between Full HD + and Quad HD + based on the content being displayed.
Web browsing and internet usage is a very typical use case that allows us to get a good idea of battery performance. We've played a series of battery measures that simulate a typical blowing level at all the display variations available on the OnePlus 7 Pro. The results tell:
Predictably, the best battery life you get is set to Full HD + (2,336 x 1,080) and the refresh rate is set to 60Hz. The battery life goes down at 692 minutes of web browsing.
We noticed a significant decrease in battery with the screen refresh rate set to 90Hz. The phone managed to achieve 498 minutes of continuous web browser.
Screen resolution to a fixed Quad HD + (3,120 x 1,440) resolution results in similarly interesting results. To start, start battery life at 552 minutes of web browsing when set to 90Hz. This brings up to 60Hz to a more respected 605 minute scrolling time.
At the highest settings, a 5.5 hour screen time is much lower than expected.
In average day to day use, screen on time varies dramatically depending on the institution used. With the highest resolution and display at 90Hz, screen time was only about five and a half hours. It's considerably lower than what we see on OnePlus devices and what you expect from a phone with a 4000mAh battery. Reducing the resolution and refresh frequency brings it more in line with the seven hours or more screens at the time we are accustomed. Unfortunately, this is something that would not be obvious to the average user and could lead to less than ideal user experience.
Suitable, the phone shears with a handy adaptive mode feature where it can change resolutions based on the usage case. We encourage you to set the phone to automatically switch on and adjust it in a dynamic way based on content.
The refresh rate is where things get difficult. A great selling point of the OnePlus 7 Pro versus OnePlus 7 is that extra smooth experience brought along by the 90Hz display panel. If you're willing to dive into battery life, it's hard to go back to a 60Hz screen after trying out the buttery smooth experience at a high refreshment panel. However, if you run on your own, consider switching to the 60Hz mode.
What do you think? Is the less ideal battery life enough to consider the OnePlus 7 over the OnePlus 7 Pro, or are you prepared to sacrifice battery life for a smoother user experience? Let us know in the comment section.
