by "booster" I think you are saying/meaning "network extender" ? That is for the cellphone DATA connection to your carrier/ATT/Verizon/Sprint?
I moved to a rural area w/o Verizon coverage. The other folks did not provide good coverage either and the phone was always roaming looking for a better signal. I purchased a Network Extender "mini cell site" from Verizon that plugs into the home wideband internet router. Wallah! I now have 5 bars on a carrier name of "Network Extender". works great.
My router is also plugged into a
Buffalo WiFi router so I have a huge circle around my home with great WiFi.... I have the guest account turned OFF, and the primary account locked tight. No freebies for my neighbors to slurp up my bandwidth.
Now, your problem. Give us some screenshots of BATTERY, so we can see what is happening there.
I am assuming that you do have Wideband cable or DSL to your home for internet?
That is what you want your WiFi to be working from.
Also, how about logging into your WiFi router and changing the name of your WiFi account. That will force the S5 to ignore the old signal and log into the new signal. While you are at it, do NOT leave the WiFi channel on '11'. Turn on Channel 1 thru 6. I chose '6' because it is weird and no one will be looking for it there. Channels 1, 2, 3 are the strongest your router will be able to put out because the frequencies are lower and have better range. Experiment around a bit.

Each of those apps has a nitch in the tools arena. I look at each of them to get an overall picture of what is happening around me.
WiFi Overview 360 Pro has a tab labeled:

it will show you what channels are free.

If you have a neighbor(s) with WiFi signals, your S5 is going to have a rough go of it trying to stay logged into your router. That is going to eat up a lot of battery, especially if some of those signals are weak and your WiFi is really ramping up the transmit power to reach them.
Using the above tools will let you learn who/what is in the air.... then you make damn sure that your force your WiFi onto an unused channel and lock it tight with a security password.
Do NOT leave an open channel available for the neighbors, or your phone to look at. You only want '1' WiFi signal period.....
Let us know what you discover.
