If it's constantly in a loop of trying, unsuccessfully, to connect to a wireless network, I could see it increasing obviously, but in a normal connected state, as the others say, no way as much as mobile.
alright awesome ill keep using wifi

Scott is right. If you don't have wifi connected it will constantly search for it causing battery drain. If you leave and don't plan on being on wifi I would shut it off so that your phone isn't constantly searching for a network. There are some battery settings in the wifi menu that can help with that though just not very much.
P.S. oops edited sorry Scott lol

I'll take that as a complement.
I disagree, every phone i have seen uses significantly more battery having wifi turned on, I definately notice it on mine, and im talking about being connected to a wifi the entire time. My battery life with wifi on has always been **** compared to it being turned off, Iphone's all of them including 4, droid x, vibrant, captivate, inspire all the same result with wifi enabled.
Do a expierment charge phone to 100% before going to bed, lets say 10 pm to 6 am check battery power lvl, next night enable wifi, I am absolutely certain that u will have a much larger drain.
as for does it drain more while in use than 3g or 4g is another issue, some say it uses less than mobile network to transfer data because a mobile tower can be a few miles away while the router is no more than 200 feet. I personally think wifi still uses more battery, however i do use wifi when available to keep my data usage down. if u disabled 3g altogether then maybe. but with both on u are powering another radio.

If you're saying that having WiFi on uses more battery than having WiFi off, which is how I read the first part of your post, I'd have to say you absolutely correct.
I think the question was whether WiFi used more battery than mobile data.
Mobile data uses more battery because its constantly trying to look for a better connection. E/3G/4G/ETC...

according to alot of other post about this same issue say wifi uses more battery either way because your 3g /4g radio is still on when using wifi
Both right
If you have WiFi always on, constantly polling for it, when not connected, you will use >battery. If you are connected to WiFi, and thus not polling all the time, <battery usage.
I use Llama to disable my WiFi when I am out not using GPS. It knows I leave home or work based on location as tringulated by the cell towers, thus GPS doesn't have to be on. Your phone is always polling for towers anyway, even with data shut off, so this does not use any battery to speak of. There are a lot of towers here in my basic hood, so Llama seems to identified that I leave home from 100-1000 meters, depending which direction I go.
You will use less battery if you shut off WiFi polling while you have no chance to connect to Wifi, that is for sure!
I use Llama to shut off and on all sorts of stuff based on location or a set of conditions. It is all logic based: If condition A exists, perform B toggle. Works great for me in an area with lots of towers so location at home vs. work vs. out is determined rather easily and accurately in my experience.
Edit: other conditions available include days of the week, time of day, headset or bluetooth enabled, etc.
Wifi definitively uses less battery than 3g from all the tests I've done and common experiences around the forum. Its not even close.
Can you change the wifi interval in the build.prop file to have it search after a longer delay? I know on mine it is set for 15 (seconds)?

When I'm at work my phone goes in and out of signal a lot while in the office. When I go outside I've 4G and 3 bars. The temp of my battery has been at 118F before and the battery drains about 50% per half hour.
Are there any techniques or apps out there that will solve this? Airplane mode works best when in the office, but of course that sucks.
Thanks

Maybe this can help. Airplane mode
I live in NYC and am hitting up subways quite often. I've noticed a major decrease in battery life whenever getting out of the subway due to not having any signal underground. The phone is constantly searching for 4G and a Signal and it drains.
Everytime I hit up the subway I stick my phone in airplane mode since I know I won't get a signal anyway, and my battery doesn't drain a lick. Maybe this could help?
2x battery is great

is there a wifi network you can connect to at the office? I'm in a similar situation at my office, for whatever reason the connection to the mobile network is incredibly spotty and unreliable in most places in my building, so I just connect to wifi.
otherwise, have you tried just turning off the data connection, rather than putting it into airplane mode? you'd still be able to use your phone and sms/mms (in theory anyway, depending on signal strength) and you could just turn mobile data back on when you need it. going from full off to 4G mode has always been a lot faster on my phone than either airplane mode or forcing it to stick with 3G.
I agree with number5toad, sometimes forcing 3g isn't always easy with the phone. But 2x battery app really helps my battery life!

If you are rooted, get SetCPU from here at XDAdev. You can set a profile so it will underclock your phone while the screen is off which in my experience, completely balances out the effects of the battery drain for searching for a signal. I know this doesn't exactly address your issue, but it will definitely help save battery.
can i run both wifi and 4g at the same time and will it drain my battery faster

No...so No

Well, yes and no.
You can run the LTE chip set while you have Wifi enabled. However the wifi will take precedence over LTE, so you will be using wifi for data. The LTE will be connected in background, allowing you to receive MMS automatically and quickly connect to 4G after you turn wifi off. It will drain your battery faster but it won't make your interwebs faster.

just to elaborate further - leaving wifi on without a connection is the big drainer. leaving 4G on while connected to wifi does not (but I'll be testing some experiments on this theory today).
wifi
the reason i ask is i use a app called timeriffic and can set wifi on and off at differant times but if i turn wifi off i have to turn 4g on manually
was hoping to leave 4g on so when wifi is not connect my 4g is

i leave both on all day - but I also set my wifi scan to 1800 (once every 30 minutes). this has almost no impact on my battery life. also, each time I enter an area with a known connection, it connects rather quickly.
update to this, when leaving on both WIFI and 4G (while maintaining a WIFI connection), my phone drains at about 3% per hour in an idle state. Last night, I turned off mobile data, and my battery drained about 1% per hour. thus, I'm curious to see why previously my phone was still using the mobile data when there was a wifi connection.....
It isn't"using" it per se, but it is holding the connection open and dormant so it can establish a connection quickly on need. With LTE, you're dealing with a separate radio from voice, so if it dropped the connection entirely, it would have to open the radio link before it could get data flowing, which can take several seconds or more. It's convenience over battery life.
thanks for all the great info guy i will just leave both on and see what battery life is :fingers-crossed:
It's kind of like having a hybrid car in hybrid mode it uses just electricity (wifi) but the gas is still idling (4g) but if you were to use only electricity you would have lost no gas i.e. better mileage i.e. better battery life.
I stay in a hotel room often without free wifi. Most of the rooms I get 1-2 bars, occasionally 3. A decent amount of the time I get no 4g and sometimes signal is so weak no internet at all. I notice this destroys my battery life. Is there someway to lower the extra strain on the battery when I know I will have a weak signal anyway without using airplane mode? I wanna lower the power being used by my phone to search for stronger signal while still being able to receive texts and calls. Would prefer to keep 3G on as well when it works.
On a related note, are there any products I can buy to boost my signal that work? And is there a rom or roms that are known to have great signal strength compared to the rest out right now? Thanks for any help.

You should be fine disabling Mobile Data... You should get texts just fine and use the WiFi for all data purposes.
Im not using the wifi ever unless really important to get it, $15 everyday is too much. So i am trying to rely on mobile data.
Go download the free app "Phone Info", it will allow you to shut off 4G, shutting off 4G stops it from searching and draining your battery.
Once installed, click "Device Information" and scroll about half way down and change the drop box from "LTE/CDMA/EvDo" to "CDMA only"
Hope this helps!
I use phone info already, 3g over 4g definitely helps, but am I wrong in assuming that the phone is still destroying battery when the signal is weak even with 4g off?
Hi,
I am trying to get a clear idea on the battery consumption of N5 on Wifi, LTE and E. If the purpose is to be battery friendly, which one (LTE, Wifi, Edge) should I left my phone on most of the time?
Thank you,
Well id say not WiFi! I use Wi-Fi at home and battery life is OK, it actually depends on how much you use it. I'm usually on my tablet at home and on the road my n5. Idk what E is but I'm thinking it's edge so that's probably better than LTE battery wise.

Wi-Fi is by far, the most battery friendly connection because the device only has to transmit and receive from a very short distance. Mobile data signals have to travel to the cell tower so more power is used the farther away you are from it. Less bars, more power used to communicate with the tower. LTE is best because you get that transmission completed very, very fast. HSDPA is good as well. Edge connection is very slow and makes the device hang waiting on the package to be sent and received, thus using more power in the long run. I usually set my phone to edge when I'm not going to be really using it.
Hope that helps.

You certainly want to be using WiFi at home. I tried going data only for a couple days because it's unlimited and the battery drain especially while idle was much higher than using WiFi. This is with full signal 90% of the time.
WiFi is your friend for extended battery life. Mobile data - whether it's LTE, 3G/HSPA+ or good old Edge/2G will vary in power but it's pinging the towers for signal & cycling, so it will use more data - that is, all other things equal in terms of settings including the newer/est KitKat features.
Wifi whenever you can use it.
As far as cellular, as long as you have a decent signal, faster is always better (so the modem can download what it needs and turn back off). So use LTE if you're going to be using any data. Knock it down to edge (or off entirely) if you don't want to use data at all, or just for the occassional notification.
So Wifi is clearly the best. So when my phone is idle for a long time, let say at night, should I leave it under Edge or Wifi?
I am writing a tasker profile, so I just try to see which one is better in term of battery.

Well you can always put it on airplane mode/turn off the mobile radio and switch on Wi-Fi after to just have Wi-Fi data. The catch is, you will not be receiving any calls or SMS/MMS while you have the mobile radio shut off... unless you're using a VOIP service.
