One of the best screens you will find in this budget, the display is extremely smooth and fluid and has great brightness.
Performance of the phone is also amazing it is very fluid and for everyday tasks it will handle everything flawlessly, works great for gaming too unless you want the absolute best performance in gaming.
The main sensor of this phone is very good, takes very good images in well lit conditions and does well in dark conditions too if you switch to night mode, only suffers in very dark conditions but that is expected at this price range.
Battery life is good it will easily get you through one day, and the fast charging is amazing, from 0 to full in approximately half an hour.

Quality:Good
Performance:Great

This is one of the top mid-range smartphones.

The battery is big but if using a high refresh rate it drains faster. However, it charged super fast, so it's not much of a big problem. The camera is not the best but also not the worst. Even though the OS is clean, I disabled a few apps.

This is my 4th OnePlus phone and I am disappointed by the product fragility. In less than 24 hours after I received the phone and (unfortunately) before I receive the phone cover, the phone fell once indoor of 70cm height: the plastic frame of the phone bended causing the back glass to crack over 10cm and even to lose a small piece of glass. How is it possible to make a phone so fragile?

I even not use mobile idle condition also battery drain
When I'm use mobile 2-3 min 1% battery drain really very disappointed ☹ buy this model

but after update oxygen OS 13.1 little bit Good
