@Kyle Crane Ambient temperature, your use cases, location, calls, and signal strength will be a control challenge for this test. Good luck!

Great question.
5G NSA is essentially LTE core + 5G radio. It is primarily used for thickening the data pipe.
It does not deliver true 5G capabilities like ultra-low latency, network slicing at the UE level, or service-based architecture, because the control plane and frame structure are still LTE-anchored with backward compatibility.
As a result, NSA offers limited real-world benefits beyond peak speed bursts. In practice, speeds cannot be leveraged everywhere because low-frequency bands (which provide indoor penetration and coverage) remain on 4G. This makes 5G coverage non-ubiquitous, leading to frequent 4G–5G switching, which actually hurts handset battery life rather than improving it.
Now coming to 5G SA.
SA can deliver better power efficiency and real 5G features, but only if it is built on a strong foundation of substantial low-frequency spectrum. Deploying SA with just 10 MHz in 700 MHz is neither here nor there. It is insufficient to support meaningful UE-level slicing, as slicing without adequate spectrum would choke the best-effort pipe, cause congestion, and raise net-neutrality and regulatory concerns.
Yes, 5G SA can improve battery life, provided the operator manages band and network switching intelligently, and carrier aggregation (CA) can further help. But without adequate spectrum depth and coverage, SA alone is not a magic switch.
Hope this clarifies the practical difference between 5G NSA and true 5G SA.
