I think Mobile Data...because the Radio of the phone is already turned on either ways..uing Data or not, and when using Data, I guess it only causes a slight increase in battery consumption.
On the other hand, WiFi is an entirely different hardware component that will need its own battery consumption share.
So both Radio and WiFi being On, one for regular cellular connectivity, and the other to provide Internet connectivity, that will surely increase battery consumption.

Wifi uses less battery. Mobile data uses alot more battery because your phone always has to search for a better/stronger connection ( that's where the option to only use 2g comes it). Also wifi sends and receives data faster which lets your phone take breaks (idle) between pushing and receiving data. Mobile data slower speeds takes shorter breaks and always has to check in with the network (fast dormancy is a new tweak to reduce that check in frequency, included in newer roms to save battery).
If you are using GPSR (Mobile Connection) it will cost less battery than WiFi, I Think...
GPRS cost less battery than wifi
and 3g cost much more.
and the weaker the signal is,the more battey is cost.

Any expert can tell me why 3G Data Connection consumes more battery than Wifi?
I have done experiment on turning on just:
1. Wifi
2. 3G Data connection
All other functions/apps stay the same.
1. lasted over 20 hours with minimal usage
2. lasted no more than 13 hours with minimal usage.
Any expert has an explanation?
I'm not an expert, but I've observed the same thing that you have, 3G uses more power than WiFi, both at idle and "in use" (such as streaming music).
On my HTC Hero, using WiFi, 1%/hour idle, approx 2.5-3%/hr "in use". With 3G, approx 4%/hour idle, 10-15%/hour "in use".
It takes more power to boost up your transmit signal from your phone to reach the cell tower 2 miles away compared to the wifi hotspot 5 meters away?

thanks
yeah, because i was thinking when using wifi, there is an extra device running.
but when on 3G data, shouldn't it be the same thing as the normal phone signal?
so why would 3G data consume more battery than wifi? thats what is puzzling me.

3G (UMTS) and 2G (GSM) are usually implemented as two different subsytems. 3 years ago, when I was working with their designs, devices actually had 2 antennas internally, because of optimsation for different frequencies.

i am no technical person but I am guessing .. that means when I turn on 3G data, I am using something that is NOT related to the original phone signal connection and that is why it consumes battery on top of the original phone signal connection?
and so happens the UMTS consumes more battery than Wifi too?
Wifi just sucks more battery in general

Hi,
I was thinking which consumes less power on a Note 10.1
Wifi or 3G?
Anyone got any info on this?
plz google it... it can affect all gadgets pertaining to ur question.
http://androidforums.com/samsung-galaxy-nexus/503684-wifi-vs-3g-battery-life-wow.html
According to wikipedia typical power usage for wifi would be 32mw and typical power usage for 3G would be 500mw.
That would make wifi about 15x more efficient.
Ofcourse there are many more variables like howmuch processing power is required to handle the connection and the distance between you and the accesspoint. But considering wifi is faster and needs less transfer time to finish sending data and considering the above I reckon you should leave wifi on to increase your battery life.
I do feel that wifi is much more battery saving than 3g too. hope this help
3G/4G is a power hog as long as its on, whether you are downloading data or not.
WiFi is MUCH more efficient.
And I'm talking at LEAST 50% more efficient.
Here is my questions :
No doubt , when using phone for data , wifi is more battery friendly.
But what about just staying in sleep , not using it , having skype and whattsup opened just in case someone contacts me...
So , in Idle , wich one is battery friendly ?
In my opinion it is the mobile data, because the modem is always opened , so it does not consumes extra battery .
But if you keep your phone on idel connected on wifi , u`ll have both data modem opened (for incoming calls) and the wifi modem opened...
2 hardware pieces that eats battery....
So in my opinion just staying on mobile data in idle saves more battery.
i`m expecting more opinions...

I agree, but IMO, when I want to save more battery, I'll just switch to "2G Only" mode, that'll make differences
and if I need connection, I simply just switch back to 3G
WiFi eats far, FAR more battery than 3/4G.
If you really want to spare your battery, you could just turn Mobile Data and WiFi off, and manually turn on Mobile Data for a few seconds every hour. Whatsapp delivers messages the second the data connection is made. That's how I do it, anyway.
There's probably even apps that allow you to set an automated task to turn on the data and turn it off again a minute later every set ammount of minutes. I've never looking into it though.
What type of phone do you have? With a CDMA phone, if you are not close to a cell tower, the phone will put more power into the antenna in order to try to get a signal. This is true with all CDMA phones, so you may want to take that into consideration. Having an established connection consumes far less battery than having a wavering signal, so I would suggest leaving it on whichever you have the strongest signal, being wi-fi or the mobile network.
Personal experience with an iphone 4s, Wifi tends to drain more battery from my phone.
However, I feel both Wifi and 3g is a battery killer,
if I turn those 2 off, my iphone 4s could stay for 2 whole days on regular usage.
With either of them turned on, it could barely last a full day.
I would agree with the others. Wifi for data is indeed friendlier, but when it comes to sleep mode, mobile network is the way to go.
I don't know if it is because of the reason you mentioned about the 2 hardware pieces, but it sounds right..
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.
Hey there.
I use tasker to turn mobile data off as soon as I connect to my Wifi. When I go out of range, it turns mobile data back on.
That works great, the thing is I just read that the OS automatically does that for you, so... Am I being redundant? Is my tasker profile useless?
Thanks!
well, if you are on wifi, you are not connected to mobile data, youre connected to wifi so mobile data has no way of flowing in and out of your phone until you connect to a mobile connection.

Keep Wifi ON and Mobile Data ON, when your phone is close to a known wifi it will use the wifi instead of data and when you leave the wifi range it will go back to data by itself.
OK, I should have probably added that the purpose of this Tasker profile is to save battery life. As far as I know, not having to be connected to 3G or 4G would consume less power. Right?
EDIT: I mainly ask this for scenarios of really low data coverage. At work I barely have 1 bar, and the radio keeps switching from 2G to 3G and 4G. I'd assume that does indeed consume a lot of power even though I am connected to a Wifi network.

im on lte 100% of the time, and never ever use wifi, and i get 5-6h sot every battery cycle. really, youll get your best battery on the fastest, highest quality signal(data/phone) available for you to use, whichever type of signal it is.

Well if you have Wifi toggled ON and DATA toggled ON too, the wifi would put the data on stand-by mode and when data come in it would put the wifi on stand-by(and you can also go to wifi settings>advanced>wifi optimization[helps with power saving] while wifi is on and running).
Sorry guys, I see I edited my post while you both were replying. See:

So my point being, data might be put into stand by mode, but my guess is that the phone constantly switching radio modes and having to deal with low signals might consume more power than with data off. Don't you think?
Thanks!

if its constantly jumping to differing signal types, and quality is low when it is connected, then youd probably get better battery life with the data connection off.

However, he's thinking that you need to turn off mobile data while WiFi is on. This isn't true, it turns off/goes into standby until you need it.

Where you can save a good chunk of battery is disabling WiFi while using data. You also need WiFi always scanning turned off for this to work.
As you have found out data is switched off automatically. The reason some people are doing that now is it might be a temporary fix for some WiFi connectivity issues.
