Will toggling Wi-Fi on and off drain your battery? I'm asking this because I read:
http://www.androidcentral.com/android-101-save-battery-keeping-wifi-alive
Essentially, you want your Wi-Fi sleep policy to be "Never" because when the Wi-Fi sleep policy is "Always," your phone searches for Wi-Fi more often and that drains battery (I think that's what it is saying).
At the moment, I toggle the W-Fi on every time I'm using it and off as soon as I'm done using it in an attempt to save battery. I'm not sure if this actually works or it's actually draining my battery because it would search for Wi-Fi every time I toggle it on.
On my Samsung Galaxy S4, I can't find Wi-Fi sleep policy as mentioned in the article, but I found "Keep Wi-Fi on during sleep." Am I supposed to set this setting as "Always" to save battery life?
Thanks.
P.S.
I toggle Air View and Smart Gestures on a frequent basis as well--not sure if I should do that too.
keep wifi during sleep-always will drain your battery as even if u don't use your phone wifi will be still on

Hi
Just looked at spare parts battery history and noticed "wifi running" is reporting the same level/% as "wifi on". Is this an indicator that wifi isn't properly sleeping on my phone?
I have wifi set to sleep when screen is off in wireless & networks advanced settings. I could have sworn that in SC 2.9 and earlier, "wifi running" was reporting much lower than "wifi on" with this setting. Also I am experiencing worse battery life since flashing 2.9.2.
Anyone else having the same behavior? Any ideas?
Thanks.

Quick test for those that are having high battery drain due to the newest firmware release, with lots of usage being attributed to wifi...
If you have the wifi sleep policy set to never (Settings, Wifi, Advanced Wifi, Keep Wi-Fi on during sleep = Never), if you turn off the prime, can you still ping the IP address listed that's assigned to the prime when it's in sleep mode?
If I set it to sleep / close the dock, wait 5 mins or so, then ping it's IP address, I get a few timeouts then it starts responding...
If I start pinging it when it's awake, I get ~250ms pings, if I sleep the prime it times out a few times then the ping jumps to 700ms odd...
To me - this indicates that the wifi's not sleeping properly, when you sleep the prime it should stop responding entirely...
Does anyone else get this?
I've never had a wi-fi battery problem issue so far.
But there a setting in Asus Customized Settings, all the way down 'Disconnect Network during Sleep'
it at the very least logs you off Skype and doesn't sync/receive emails when you close the lid on with the dock.
Cheers

Correct.. but 21 increased battery drain, probably because of changes in WiFi power. They wanted to fix the weaker reception, many are experiencing.
Otherwise, you suggestions are very good.
There is another thread about it...
Can someone clear up what it means for the battery when both Wifi and 3g are enabled at the same time but only one is connected? So when I pull down my status bar (on Gingerbread) both are lit up. Depending on where I am, only one will be connected. What does it mean (battery wise) for a constant on Wifi connection to have 3g data enabled at the same time, and more importantly what does it mean to have 3g enabled and wifi enabled at the same time yet set to sleep/never? If I toggle wifi when the screen goes on via a battery saver, is that causing more battery drain constantly turning the wifi on and off than having the wifi kept alive (still sounds like this would not save the battery from the name but that's what I read!) Surely if there are only a few hotspots I connect to, it seems that using a location based wifi manager to turn it off when traveling makes sense. But when at a location, even on battery, is it best to just leave the wifi on constantly or would toggling with screen off save more energy?
Toggling it would increase battery life.

What the title says. When my WiFi is off, my batter you does not move when idle or active. When WiFi is on my battery dies really fast
Have you disabled Wifi Always Allow Scanning under Advanced Settings?
Yo,
I dont know which settings are best in terms of wifi/LTE.
I ready I shouldnt have turned on in same time LTE and wifi, is it truth?
But I dont see another working options tbh. If I get bixby routines with leaving home and turning on LTE turning off wifi I need to have GPS on all time. Also if Iam changing by myself turning LTE and WIFI I always forget to turn off LTE and turn on wifi when I am back at home.
What settings u advice me to use for best battery lifespan

Actually, data is unused when wifi is enabled and connected. If you want to have data to be turned off, then you can create a routine. The only downside is if you are not connected to wifi, data will be enabled but wifi will still be enabled. For this, you need to manually disable wifi. But, keeping the wifi enabled throughout shouldn't really drain the battery a lot or so I have read!
