- Honkai: Star Rail
…at the highest graphics resolution. Normal game sessions don’t cause frame rate dips on both phones.
The iQOO 13, on the other hand, upped the ante a bit. Under heavy workloads, iQOO’s gaming software enables for more extreme GPU tuning and sustained higher frame rates.
OnePlus 14 is a more balanced device. It is more about thermal stability and long session gaming rather than maximum performance in short games.
In practical usage:
- iQOO 13 provides a little better maximum gaming performance.
- OnePlus 14 is more resilient over time.
This distinction is apparent after long sessions of playing, which are longer than 1 hour.
Cool performance and thermal performance.

The iQOO 13 uses Funtouch OS, which is more heavily geared towards games.
It includes:
- Dedicated gaming dashboard
- Enhanced GPU controls
- Touch sensitivity tuning
- Real-time frame monitoring
- Advanced cooling management
For the advanced users and competitive gamers, iQOO offers more options for tweaking the gameplay.
But, OnePlus offers a better overall software experience for the everyday user, apart from gaming.
Camera and Daily Usage.
This article is all about gaming, but daily usability is important too.
