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..

Anybody which consume more battery? My initial though was WiFi would drain more battery since you'll need to turn on both phone and wifi radio, and Edge you only need to turn on one. But it turns out that EDGE take more battery for the iPhone. So i'm wondering if anybody done any real world testing of which drains more battery. I know that there's some app out there that would measure battery drain but that's per application basics, not the actual connection itself.
Well, you can turn the phone off when you're using wifi. You just won't get any phone calls (which may not be a bad thing).

I think he means the power consumption required for using edge to surf the net.
I never thought about it, but since I'm rarely within a free wifi network outside, so this won't matter to me

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...
Sent from my T-Mobile G2 using XDA App
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)?

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.
Hello to anyone who read this thread :fingers-crossed:
My question is, when wifi is on, and I'm connected to a network, like home, work, school, etc. If 2G or 3G is also turned on, it isn't transfering data, but, is it consuming battery juice? just a little? or a lot? or none?
It's just that i'm lazy and think it's better that when I leave a wifi area, the phone keeps connected and I wouldn't have to remember to turn it on.
I don't like to use any kind of auto toggler or anything like that, and if it doesn't use battery, think my life would be easier
Thanks!

Yeah definately don't use an auto toggler those take more battery than they save. And over my years of android use i have never experienced a noticiable loss in battery from leaving data on while connected to wifi you should be just fine leaving it on as far as battery goes. It is true that you device can still use the data connection while connected to wifi (for instance MMS) but really I haven't noticed any extra battery suck.

leaving 3g on while wifi is connected doesn't suck your battery.. however I would recommend you to see that you don't leave wifi on when you are not connected... searching for wifi networks really takes hell lot of a battery :/
Great
Thanks for the answears, so now I'll keep the data turned on all the time.
Hey guys just a quick question. I already get phenomenal idle drain. I don't drop a single percent overnight in an 8 hr period. Couldn't be happier. I also have no wakelock issues However I want to help battery life while not idle.
So I created a tasker profile that enables data when only in apps that need it like Tapatalk. Then when I exit that app (screen still on) or turn the screen off data shuts off.
My question is if I'm going more harm then good with the constant data toggling. I know it's probably subjective to how much I use these data apps so data gets toggled. Is there a way to test this myself?
Not worth your effort. Don't try to micromanage too much.
thats right, enjoy your device instead.
OK thanks guys

How do you get this?
I would just say to one day use your data toggle, and don't the next day if you're curious. I'm usually curious about these things too. I set my Tasker up so it switches to 3G when I'm connected to my work's wifi. My whole work's area has very strong 3G and very weak LTE so I have bad signal because the phone keeps trying to connect to the LTE network. However, my work's wifi is also not very stable and it keeps disconnected which leads my phone to constantly toggle between 3G and LTE. I'm not sure if this affects battery drain but it felt a bit like a drain. I just ended up manually toggling. But I'm usually curious which what drains the battery more. Since your data would be off when the screen is off and if you're not using wifi you should get very good standby time.
