Not a firm believer in Intel when it comes to mobile SoC. The Zenfone 5 according to my female cousin has poor battery life. The Zenfone 2 only got a 59 hr rating from GSM Arena and 7+ hrs SOT on video playback which is ok but could be better if it is packing a 3000 mAh capacity. It seems when it is idle, Intel SoC seems to drain. This is also happening to my ASUS Transformer Book T100. In constant use, I can get 9-10 hrs SOT. While it sleeps, it drains 50% overnight. I really hope ASUS goes Qualcomm next out like mentioned in a previous article.
The Zenfone 2 was just released in my country recently. About 10K PHP (or $225) for the CL550 variant and $50 less for the 5-inch CL500 variant which is more like the Z5 successor. The 4 GB RAM variant is the way to go but I still don't trust ASUS as much when it comes to quality. Tech Radar mentioned poor build quality and poor camera. Plus there are so many choices for us here with similar prices. Huawei Honor 4X, Honor 6, Zenfone 6, and Meizu M1 Note could all be better alternatives. The Meizu M1 Note might be the best smartphone here for under $200 but it suffers at low speaker sound. My choice is really the Huawei Honor 4X with its weaker Snapdragon 400 but very good battery life and camera for its price class.
