My battery stats show wifi as on most of the time even when my wifi is off, continuous scanning and available network notification are off so why does the phone think wifi is always on?

It's a bug. There's a thread about it somewhere. WiFi isn't actually on, it's just reported that way in battery stats.

Do you get the color change as described in this thread? http://forum.xda-developers.com/showthread.php?t=1261253
Mine does this
My bionic also stays connected to the mobile network when wifi is on and sometimes it will pull from the network instead of switching to wifi. the radio is all messed up on my bionic.
Well is not a mess I mean when I am connected to wifi my phone use wifi internet instead the mobile data but I guess with wifi n mobile data use more battery I guess I don't know the revolution is like bionic the same happens

I see this on mine as well. I know some people have indicated that it is not really connected to 3G, here is what I'm seeing:
When Wifi is turned on, the 3G (or 4G if lte is enabeld) sometimes stays on. Sometimes it changes to white (indicating that it may still be connected, but not syncing to google through that connection), sometimes it stays blue, and once in while it actually goes away, but not often.
Some other threads seem to indicate that this is just a display bug. However, if I analyze my battery stats, I think the connection is actually staying on. Here is what happens:
* With just a plain 3g/4G connection and no wi-fi, if I look at the battery stats for Cell Standby, the "time on" increases as expected. If there was a period when the cell signal was dropped, I will also see the percentage ot time without a signal.
* When I turn on Wifi and the 3G icon stays on, if I look at the battery stats, the Cell Standby's time on continues to increase, but not the "percentage of time without a signal" also increases. This seems to indicate that the cell signal is staying on, but it knows it is not connected and is searching for a signal. I'm not sure if this is actually eating up more battery like when you really don't have a signal and it is searching, but it is being reporting that way at least.
* If I install a widget to disable 3G/4G while on wifi, the icons go away, but I still see the same thing happening in the battery stats. This could indicate that it is still connected, or it could invalidate what I'm seeing altogether, not sure.
In any event, I'm not sure what the real story is here, I never had the icons stay on with previous devices (Droid X and X2), so I never investigated the battery stats. However, I see alot of people talking about their Cell Standby taking up a lot of battery, I wonder if this plays in to it.

yeah I don't think it's really on either. I verify this by using speed test. I know my speed at home and lte is faster. lol
When I use juice defender I disable mobile data when connected to a wifi SI icon disappear this happen with the revolution and bionic I don't see on tbolt nor charge

My 4g icon stays on while connected to wifi and stays blue. But according to speedtest the speeds reflect connection to wifi.

Mine is doing the same, but its still draining the battery like CRAZY when browsing on supposed wifi... Definitely a bug.
Mine is the same way but I can't use anything on my network like google tv remote or printershare it says it can't see anything on the network. Tried other phones and they work

It should prefer wifi over 3G/4G. I keep this page bookmarked on my Droid that shows IP and ISP name to test it.

I have been on wifi all night. 3g lights on. However, my data useage for the month have not changed. I am confident that 3g is not being called upon

My experience is similar.
Hi, when I'm abroad using wifi (so no cellular data), my battery lasts longer compared to being at home, also on Wifi. how can this be possible? shouldnt cellular data be deactivated as soon as i activate wifi?
thanks in advance

Depends on what Wi-Fi network you're connecting to. In theory - 5Ghz network takes more battery than 2.4Ghz or a/b/g network. Also, signal strength also plays it's role - constant low signal forces the antenna to work harder - and at home you always get good signal.
Who knows, maybe that's the reason.
Maybe when you are home the data connection stays in the background waiting for you to drop off wifi network and therefore eats up the battery
but when you are on roaming the data connection is turned off completely to save on data bill
this is just an assumption...
what I usually do is when am at home or work, I turn off data and turn on wifi manually instead of letting the phone choose for me. I've found that this helps in conserving battery
No, thats not how it works.. Your cellular data connection is active, just unused.

I do this too, in fact I use Llama to do it for me. It saves a lot of battery.
Thanks, that's what I thought. But why can't android simply deactivate data when connected. I don't get why there is no such option.

When internet access (either idle or during active use) is necessary, what is the better option for battery life?
Does Wi-Fi drain more battery, is it the other way around or is it the same?
Best option for bettery life is to leave wifi on when your in wifi area

Wifi saves more battery than 3g.
Sent from my GT-N7000 using XDA
yes I agree Wifi drains less battery than 3G if you have a good wifi connection, but not if your phone is scanning for new wifi connection when you travels.
To be clearer, wifi is the best option at home or hotel room compare to DATA transfer (3G).
Thanks, I always thought that 3G needs more battery juice. Every day you learn something new.
Damn me to i always taught 3g would use less. Thr note battery still needs to be inproved.

But if you are at home , WIFI is on and the screen off - actually this happens the most time.
I marked the option in the advanced WIFI-settings that turns the WIFI off when the screen is off.
What happens then? Does it do all network stuff with the 3G connection or is there a WIFI-wakelock for apps like Whatsapp?
If it uses the 3G network would't it be better to change to 2G?
Iam not sure this helps something but iam acutally doing it like this. Always on 2G (because at home and at work i have WIFI) and only when i need 3G when iam not in a WIFI-Network range i switch to 3G.
Does someone know how Android works?
Wifi is always better than 3g
Saves battery
saves money
And in many cases faster speed than 3g
So I will go with wifi

I have an issue where WiFi will turn itself on even if I had it off in settings. It has happened when WiFi and mobile data are off and when only mobile data is on WiFi will turn itself on. I only noticed this when I had both radios off to save battery but turned screen on to check the time and saw it on. Anyone else had this issue or knows of a fix. I am stock, unrooted and on 4.1.2. Thanks

Do you mean keep WiFi on during sleep? If I leave WiFi that doesn't bother me. It's when it's turned off, it turns itself back on.

I've recently noticed that even when I've switched off my Wi-Fi, the battery meter shows (claims?) that Wi-Fi is still active. I haven't tested it enough to see what effect this has had on the battery life, but still I'd like to know if anyone else has noticed this oddity. Is it common or just my phone?
Screenshot attached. WiFi was initially on for the first 10 minutes or so, and then switched off. WiFi scanning is set to off as is use WiFi networks to determine location.
Anyone have any idea whats going on?

My Pure edition has the same issue. From what I can tell, it does turn off and is just a meter issue.
Same here. You need to reboot while WiFi off to solve it.

To avoid this from happening you can disable the WiFi while still connected to the WiFi network. Otherwise it's a visual glitch with the Lollipop graph.
You need to turn off scanning always available in Advanced WiFi settings. It's not a bug or graphical glitch of any kind.
