Brightness is about 30% all the time (almost) I don't use 3G much since I'm always in between home, job or some cafe WiFi network. I switch off WiFi ocassionally. (when I remember to) My Advanced WiFi setting has: Network notification and WiFi optimizaton (wonder why yours says "optimisation" :) ) ticked, others are off. Economical backlight is switched off (brightness) No Xposed used. No airplane mode or overnight switching off.
Right now I have 23% left, 3d 15h on battery and SoT is 3h 40 min. Battery drains the funny way as you can see from images. It was at 45% for more than 2 days and it dropped to 0 in 10 minutes :) I have this much capacity only if I charge it to 100% and it stays on the charger like that for an hour or so... Otherwise it is 1.5-2 days cycle
Did you install vcom autoinstall drivers? Now for something completely different, Coolpad's marriage with Qihoo 360 (coolpad quit rom development for F1 and other phones and transferred that to 360) is going to break down ugly very soon. Qihoo asks for $1.5 Billion payout.
