Realme GT 7 vs OnePlus 15R?

Hi everyone, I am deciding between the Realme GT 7 and OnePlus 15R. Both are almost the same price in my market.

Current phone: Oppo Find X5, used for around 3 years. Main issues are heat, bad battery drain once warm, and performance drops, especially with Maps, Android Auto and charging.

My use is mostly WhatsApp, Instagram, YouTube, Maps, Android Auto, Bluetooth music, browsing and casual games.

What I want:

1. Strong battery
2. Good thermals
3. Smooth daily use
4. Good display
5. Decent camera
6. Reliable 3 year ownership

I looked at Pixels, Samsung S/FE models, Nothing phones and other OnePlus/Realme options, but narrowed it down to these two.

I like both phones a lot and currently lean toward the OnePlus 15R because of the bigger battery, Snapdragon chip and OxygenOS.

The only thing making me hesitate is the camera compared to the Realme GT 7, especially the GT 7 having a dedicated telephoto camera.

For people who used either phone: how are battery, thermals, software and camera in real daily use? Would you pick the GT 7 or 15R for long-term use?
