I don't mind apps too much (which is why I've used Windows Phone in the past), so really all that matters to me is the multimedia experience, stability and battery life. The Idol 4 has quad speakers while the Lumia 650 has one front-facing speaker. The Lumia has a 720p AMOLED display and the Idol 4 has a 1080p IPS display. The two run entirely different operating systems and that definitely affects their stability, performance, and battery life. Windows 10 Mobile compared to Android has amazing battery life, but the stability and performance dropped from its predecessor, Windows Phone 8.1. Someone who owned the Idol 4 and Honor 5X said besides battery life, the Idol 4 is better.
