I have a feeling you could improve the SoT by manually optimising battery usage for individual apps. I have done and get nearly 6hrs. EMUI has gone from stopping everything to allowing everything with the update to 5.0.Unfortunately 3 hours of SOT did not cut it for me, I'm back to my Exynos S7 Edge. I'm a pretty heavy user and S7 Edge almost makes the 5.5 hour SOT with my usage pattern. The Honor 8 is listed on the marketplace.
