Not the original poster but the iPhone 5 had a 1440 mAh battery while the iPhone 11 has more than double that with a 3110 mAh battery. For comparison, iPhone 5 was rated at 10 hours video playback while the iPhone 11 is rated at 17. So ballpark guess, that hybrid version would have ~8 hours video playback compared to the iPhone 5's 10.

Rough numbers all around, especially since battery usage is largely driven by the display, RAM, and CPU.
