I've searched and saw a bunch of BS about this option.
Here's what I've found.
1. When you turn it on, it's beats your battery. About 4% battery drain per hour vs >1% for normal wifi from what I've seen.
2. It doesn't make your wifi 'faster'
3. What it does do, it fixes the wifi disconnect issue.
#3 expanded. Some EVOLTEs(maybe all) drop wifi when you're far away from the access point. For me it takes just being downstairs to get drops.
If I'm in the same room as the AP, no drops, don't need this option. If I'm far away from the AP and I'm playing an online game and I keep getting kicked, this option will fix that. If I had to guess at what this option does, it must turn up the broadcast strength of the wireless card.
What I've done is I made a shortcut to the wifi settings menu. 2 clicks to turn it on and off.
Turn it on when needed, off when done.
If someone made a widget for it, that would be badass.
I've found just the opposite, it actually makes my disconnect issue worse.
Found this out myself about a week ago. Fixes my issues as well.

I had that turned on for a while because it sounded pretty harmless but it KILLED my battery life. I couldn't figure out where this huge drain was coming from, I would be losing an extra 20% throughout the day and 10-15% overnight. I suppose if you're really having wifi issues it would be worth it, but IMO I would download Wifi Analyzer and see if you're having interference issues and change the wifi channel.

+1 That's what I did and found the default channel 6 to be super crowded. I moved to channel 9 (most unused for me) and ALL my wifi issues, not just my phone, went away.

Toast95135, thank you for the info on this app. This fixed all my WiFi issues in my house too. I thought that mine was sharing a lot of channels with the neighbors. I was sharing the same channel with about 3 of my neighbors. No wonder I was having so many issues. My WiFi is also a lot faster.
Thanks again! I hit the ty button too. I wish I knew of this app about a year ago. :good:

Why does my WIFI turn off when Prime goes into sleep mode?
This is new over the past week or so. After lock screen, I have to wait 10+ seconds for WIFI to turn on and connect. Any ideas?
Thanks.
The WiFi turns off to save battery while the Prime is sleeping. After all why keep the WiFi radio on if you are not using the tablet?
If you go into Settings > WiFi > Advanced (top right corner of the screen next to "Add Network") you can change this by making WiFi stay on all the time. But don't blame me if your Prime's battery starts dying a lot sooner.

Thanks. I wonder if the last firmware made this change. Because I didn't do it.
Wifi uses barely any battery life.
I want apps like Skype to stay active like they did on original Transformer.
Will definitely be changing that setting back!

Using "some" battery is still a lot more than using "no" battery
To each their own, the default setting is for it to turn off when sleeping. However I believe one of the last firmware updates kept it from turning off, which lead people to complain about shorter than expected battery life so Asus released a new update that fixed it.
From my experience, with WIFi off while sleeping, you can leave the Prime on standby for 2 weeks and come back to find better than 80% battery remaining. That is a pretty handy feature.
Not using the prime for 2 weeks, what kind of person are you? Thats not possible.

I'm on the collective ICS Unoffical
I don't think it drains too bad but I like to turn wifi off when not in use. I pretty much only use it at home. LTE is fine everywhere else without hitting my data usage limit.
So...is there a way to have wifi toggle off once I'm out of range?
TIA
Use tasker.

What's so hard about using the drop down toggle to turn it off? Why do you need it to be automatic when it's right there all the time?
Settle down there cowboy.....
That's not hard at all and it's what I do.
But I usually forget and do it hours later.
"IF" it drains the battery by constantly looking for a connection, I'd like to minimize that....
The beauty of android is there is usually a way to do things like this.
Thus the question....
Have you tried Llama? I'm using it on my captivate, not sure if it works on ICS or the note but it is a scheduler that uses cell towers to define locations and you can have different actions occur if you are in certain locations. I have an at work set up so that the ringer is off and so is wifi, at home I have ringer on high and wifi on until 10:00 then I turn the ringer off.
I think juice defender app does just that among other things.

Have you had a look at "Y5 - Battery Saver" in the market? It's a very simplistic app, but it works pretty well in my experience.

Yes it does (at least the pro version does) -- Wifi gets activated and deactivated based on location. When it gets in range it turns on, when its out of range it turns off.
I've had issues with Juice Defender turning off my WiFi when I didn't want it off. I vote Tasker.

Tasker, at least in my experience, really needs to be paired with a tutorial. Its amazing the things it can do, but its a very intimidating program to start using.
JD ultimate does the wifi trick (Ive been using JD Ultimate until just recently). I actually feel I've gotten better battery life when I stopped using JD and switched my launcher to GO launder EX. When I had JD active...I'd struggle to see just over 3 hours screen on time. Now I see close to 4 hours, if not more.
EDIT: I also have turned my syncing off.

Thanks for all the replies.
I tried tasker about a year ago and agree with it being a bit intimidating.... I might go that route.
Never heard of llama but it sounds interesting.
I use 2X battery and it definitely helps save battery. I'm in a LTE area and that can suck it down quick. I don't need things pushed to me instantly so as long as I get texts and calls I'm cool. I can jump on data and get things sent down. However it looks like the wifi option isn't avail.
Llama is cool and did the trick. Now to see how else I can use it. It's like Tasker with a friendly gui. Thanks

I've had a combination of two weird / PITA problems since upgrading past LE6 leak:
1. Slow to lock GPS
2. REALLY bad battery life (losing 10% an hour while idle in some cases).
In the last few days I was at a conference with known poor signal indoors, so I started toggling Airplane mode on during some of the sessions. I noticed a DRAMATIC change in battery life. I thought the improvement was too good for just having disabled for about 2 hours each day, so the last two days I've toggled Airplane mode on and immediately back off after heavy use... I've done this today and after frequent use repeated the toggle routine. At the time of this posting I'm sitting at 70% at a time of day I'd usually be around half that.
Anyone willing to try this and let me know if I've just been lucky the last few days?
More info:
I've run CPU Spy and I know my phone isn't going to deep sleep as frequently as it should. I installed better battery stats and nothing was causing partial or kernel wakes so I was about to give up.
I believe this may stem from the GPS having crappy lock time, since I frequently use Facebook on the phone and it activates GPS (and doesn't F'n lock) I figured airplane mode after use couldn't hurt.
Qualifiers for a valid test include the two problems I mentioned above. If you're lucky enough to not have these issues, please recommend your settings... WiFi is off with screen off, i'm using screen filter at 38%... I've tried task killers, I've tried many different ROMs... this is the first time I've seen any noticeable improvement.
I heard that powering down your phone completely works even better...not sure though, might need to test it.
Jk. But yeah, it's well known that the radios are one of the biggest drains of battery besides the screen. Turning them off will obviously increase battery life, but it also turns your phone into a big iPod touch, as you can't receive calls, texts, etc. Add for the GPS issue, several roms have zero GPS issues, try them out, see which gives you best GPS. And turn it off when you're not using it.

The battery life advantage exists even when the radio was only toggled off for about 1s. I'm no longer leaving it off for hours.
Yeah, probably because it kills the GPS searching for satellites. So either flash a new modem or ROM. I leave my GPS on 100 percent of the time, as when it works properly there is no battery drain when an app isn't using it. The GPS is known to be hit or miss with lf6, so take that and fix it with a modem flash.
Edit: in other words, your toggle method won't improve battery anymore than a properly working modem, and it's a lot more of a hassle to you to keep toggling instead of trying different modems

Do you have a recommendation on a modem then? I'm currently using King-Kang (love AOKP and Paranoid Android... Dagr8 did one hell of an integration). I've left the kernel and modem alone since then.
I'm using LE2, you really just have to try them and see what works best for you.

what are others thoughts on some of the pros and cons of this update? i'm thinking it will actually save battery to have wifi 'always on' in standby mode rather than repeatedly switching between a on/off state which uses more energy.
It will definitely eat more battery if it's always on under the lockscreen...
Also there is an option to deactivate notifications when new wifi hotspots are around.. if you are about battery life you should deactivate this..

I keep my Wifi always on because it consumes the least battery (vs 3G, LTE, etc).
If I don't play games on my Lumia 920 the battery can last 3 days.
This update is freezing my phone Dunno why but I have tested it. I occasionally get a freeze now and then, but when the keep wifi is on, it is like every couple of hrs... Will test it more though.

Wrong unless your phone is using 5-year old wifi chip.
Correct me if I am wrong, but is the wifi on this phone an on demand type system? From what I see on mine, the wifi unless being used for an actual update or downloading other content goes to sleep when the lock screen is on. It then wakes up if there is an update pushed to it or if something else needs it or of course if you unlock the phone. At least that is the way it appears that mine works.
Also your radio service are going to use much more power than the wifi will as they are higher power transmitters and receivers. There is a reason wifi only works within a few hundred feet and radio works for several miles that is due to the power difference. Of course with more power you get more battery consumption.
In the case of conserving the battery you are better off to use wifi when possible, leave it on and let the phone control it.
In my experience keeping Wifi on permanently lead to a remarkable decrease in battery life. That will depend on where you are though. If I have it sitting at home where it has Wifi connectivity it's likely that I would see better battery life because all actual transfers will happen via Wifi. At work though it can't connect to the Wifi network (private phone, work network) and so I have 3G running anyway while the phone keeps looking for Wifi networks to connect to.
The problem boils down to the fact that while you can switch off Wifi completely because everything can still work using 3G you can't switch off the phone part completely because only data is done over Wifi but you still need the mobile connection to receive calls/SMS.
I would suggest to anyone to simply try out what works better for them. For me it worked best to let Wifi deactivate automatically as it had been the default in WP since WP7 came out.

Maybe Wifi is using less power when you are downloading something and need a lot of data... But when your phone is idle... Constant on Wifi is using far more battery power than 3G that checks for email or weather every 1-2 hours...
Simple enough...if you are consistently in an area with a WiFi signal, leave WiFi "always on"...it will consume less battery. If you're in an area without WiFi signal then turn it off, as searching for a signal will help run your battery down.

Again, simply not true unless you are using a 5-year old phone. Even if you are in an area that has no wifi connection, the extra drain caused by searching for Wi-Fi networks is minimum in a modern OS and modern chipset. I have left all my android phones (the ones that offer Wi-Fi always on feature for a few years now) wifi on all the time. Never have felt much difference vs if I turn wifi off. It annoys me that WP didn't offer this capability for so long.

I tested a lot of phones Android and WP, my experience is that wifi always on is a battery killer... And I'm talking about state of the art hardware... It's just my 2 cent's but i keep it off...
When I don't charge overnight and wifi is always on my battery drops about 40%
with only 3G on about 8-10%
Foxbat: you can leave it any way you want to do it. I'm not saying Microsoft should remove the feature. But in my experience keeping Wifi on kills the battery faster. I tested it for my use case with always on and with Auto and in the end: Auto it was for me.
The best advice you can give to people is: try it out yourself and you will see what works best for you.
A picture or two says it all. See the attached files for my two testing: one with wifi always on for 24-hour and one with Wi-Fi in auto mode for 24-hour:
The right picture shows 0.0%/hour under current discharge rate... pretty impressive

The keyword is 'Current' -- means at that moment. You can derive the same thing from the left in various sections. The key here is that I don't see any discernible difference. Certainly not a battery killer in any sense as you claimed.
If you look at the first 12-hour period of both chart (when the phone is mostly sleep and not used), the result is almost identical. FYI, there are three push emails connected all the time: Hotmail, GMail and Corporate Exchange Email.
Yes the keyword 'Current' -- means at that moment... so your phone is not discharging although your screen is on... Very accurate app...

So, what you saying is that if you have the screen on, you will see your battery percentage drop immediately? You should return your phone if that is the case.
Battery app get its information from the phone OS reporting. If the OS reported the same battery percentage over a short period of time, the discharge rate won't be anything other than zero. That's limitation of the platform, not app.
Instead of criticize the app which is not the point of the post, why don't you post your findings where leave Wi-Fi always on kills your battery?
it' % per hour... and your phone is using currently using 0,0% per hour so if you leave it like that it will run for ever... so where is the mistake?

% per hour is a unit of measurement. It doesn't mean you have to take one hour to measure it in order to claim its rate. That will be average rate on that hour, not current rate which is meant to see what your current usage pattern is. It can't be used to predict your battery life. If you notice that when you take your phone off the charger, it will stay on 100% for quite some time before it starts to drop. Does that mean your phone battery can last forever? Think about it before post these ridiculous statements.
Foxbat - you are trying to tell us how our devices should behave while we are telling you how they actually behave in the real world out there. You can repeat your 5 years story as often as you want to but it clearly doesn't live up to the factual reality we experience every day and I guess after trying it out with different ROMs on the 920 and leaving all other settings the same I know the effect it had pretty well.
Nice to know though that you are having a different experience with different devices.
I really hope I'm not the only person having this issue. Wifi calling is causing 35-40% of my battery usage on my device, even when turned off. I turned it off last week as it was extremely annoying having to constantly go into the wifi calling settings to re-set the location of my wifi network (I would have consistent wifi calling authentication errors until re-setting the location). Now even with it off and ALL authorized wifi networks removed from wifi calling I am still seeing this huge battery drain.
Anyone else see this happening on their devices? Better yet, anyone know of a fix or work around?
Check to see if connections optimizer is on. Turn it off if so.
It was on. Just turned it off. I'll report back with my findings.

I know I was seeing moderately bad battery life and it ended up being the optimizer. Would definitely try that first as others said.
After turning off the optimizers this morning i am so seeing 36% battery usage and 9+ hours of stay awake time on the Wi-Fi calling app. It is still disabled and the authorized list is blank. I'll try rebooting the phone and wiping cache.

When I first got the phone, the WiFi calling kept giving me authentication errors and would not work, and then after a couple days the phone just shut down on me and never turned back on again, while the battery got hot. I exchanged my phone for a new one, and haven't had any problems since.
On a side note, wifi calling has allowed me to get rid of my Airave, which Sprint gave me for free about a year ago because I was getting constant dropped calls at home.
I'm getting huge battery drain and I actually stopped the process. Its using up more than my display.
After a little more investigation, it would appear that the issue was 2 fold. Connections Optimizer was causing an issue however the root of the problem appeared to be having *any* wifi networks in the authorized list even when Wifi calling was turned off. Now that the authorized network list is blank and wifi calling is disabled, it no longer shows up in battery usage and my battery life is much much better.
Reading the success of dkratter, it makes me wonder if a re-image might correct the issue. I did enable wifi calling when Sprint was having some server issues with the authentication.
