Do battery optimization features actually reduce performance on Android sma

Lately, I’ve noticed some newer Android phones throttle app performance to save battery — especially in background-heavy apps. I’m wondering if disabling “battery optimization” genuinely helps performance, or just drains the battery faster.

I tested this while streaming’a few media apps for research, and performance seemed smoother with optimization off.

Has anyone else compared app stability or battery life with this setting toggled on/off? I’d love to know your experience across brands like Samsung, Xiaomi, and OnePlus.
