Yeah, I will have both running concurrently or manually switch, but deep sleep app is one that'll provide the means for those two bars to halt and then come back on when your phone screen is off long enough. The bars for WiFi and network would have breaks in them if no items pushed through (messages, phone calls, &c).
Also, check to see if WiFi scanning during sleep mode is set to either never or only when plugged in (from settings choose WiFi, menu, advanced) instead of always. Another item in that submenu (there are a ton of WiFi options on this phone) is automatically switching from mobile network to WiFi. You can try it on or off to see which works best for you.
These merely delay the inevitable...devs and the manufacturer can provide tools to assist with battery drain while your screen is off, but they can do little to help with power draw while your phone is awake, since how you use it drives much of the depletion rate.
That extra capacity battery is pretty awesome, but how much extra time you get from it depends a lot on how you use your phone.
Hope this helps.
