So, I read somewhere that 4g is more similar to wifi, indicating that 4g is better for the battery if you have good signal. But I notice the exact opposite, 4g kills my battery whereas 3g isn't SO bad. Can anyone confirm this?

I use 4G frequently while at work. I obviously don't use my phone as much while I'm at work as when I'm not, so it's tough for me to get a good comparison.
It does seem to me when downloading bigger items, like ROMs, 4G will take up more battery than 3G even though it will certainly take longer on 3G to accomplish the same thing.
And for what it's worth, I do get a good 4G signal while at work too, so it's not like it's bouncing back and forth between 3/4G.
From my own personal experience;
Wifi>3G>4G

Imho I think it is modem/kernel/ rom related. I certianly think there was a period that wifi was sucking the life from my phone and 4 g was sipping. Presently I think I am doing 3g>wifi>4G...but I have seen this flip arround on diferent versions.

Thanks for all the replies (literally). I've seemed to notice exactly what your saying though, I was just wondering because I heard somewhere 4g drains less battery in high signal areas. I usually get 2/3 4g bars, so id say mine is ok, but it definitely drains faster than 3g
sent from my touchwiz 4.5-ed epic
It doesn't make much of a difference for me. Probably though because my school is so close to a 4G tower? I mean I can literally see it.
4G is a seperate radio so would require more power. 3G is tied to the CDMA radio. Wifi uses almost no power when connected. So I get days of standby on weekends at home on wifi.

Funny, my device gets the opposite with 3g vs wifi. My sleep policy is set on 'never', but wifi has drained the hell out of my batter since Froyo. It's nearly as bad of a drain as 4g, when I was in a 4g area to test.
+1 and also since froyo. How I long for the wifi battery sipping days.

4g spectrum runs at a higher frequency rate than 3g. Therefore, 4g will drain ur battery a lot faster, especially if u have weak or weaker signal strength. Wifi, is low aplitude frequency rate, meaning..it an open frequency , therefore, does not require much power for high speed. 3g is moderate frequency rate. Just to clearify..3g and 4g are cdma, depending on carrier. Support information regarding can be allocated at www.phonescoop.com

I have no doubt you are technically accurate and it could be the implementation and how they are managed. If I take a full battery and leave one of these on at a tome...as of stock froyo (I think some roms may have had different results) and all gb 3g certianly is usong about half the battery being used as 4g and wifi consistantly uses more.
Sammy should talk to u guys n get theeir sheit fixed.

it also has to do with power time managment in the kernels. i discovered that between the different kernels i have tried and xda. you just have to play with the different roms and kernels and see which gives you better results.

My 4G speeds has decreased greatly here in Delaware, I used to be able to get speeds as high as in my sig (10-12mb down on my OG Evo), but since I had my 3D & now this phone its much lower, but right now I'm getting better speeds at home where I used to get horrible speeds as posted in this pic. One more thing, get the GS3 cuz Bmore will have LTE hopefully within the month or sooner.

No 4G service here in the USVI. Service has also been horrible lately. About 8-20Kbs during peak hours and 50-90Kbs during off peak hours. It unbearable and makes the smartphone experience suck compared to the continental US. The voice service also sounds like I am under water on over 50% of St. Croix.

not sure if thats exactly it, but its a signal booster you can install in your home to get signal in areas you cant.
I just got my gnex yesterday and im on ATT and get slightly better signal, i can actually text sitting at my computer, my inspire i had to hold near the window to send/receive.

When you don't have a stable connection your phone is always scanning for a better connection. So it will use more battery.
You might want to try updating your APN settings, and possibly try using 2g only at your house.

As someone else said, low signal means the phone works harder to maintain/find signal, which results in more battery usage. I work in what might as well be a faraday cage because of EMI from all of our test systems. If I don't keep it plugged in while I'm at work (or go into airplane mode), it won't last the day, even if I don't touch it.
Find a place with better signal, use a repeater/booster, use airplane mode, or keep it on a charger. Those are about your only options.
Edit: You can also use an app called OpenSignal (free in the play store) to see what tower your phone is connecting to. That could tell you if you just simply don't have a tower close enough.

It's kind of like tethering. It picks up on the signal and "repeats" the signal, except now since you're right next to the cell tower (repeater) you get better signal.
Hey!
I am living in Oman,I am going to buy a Galaxy Note II,I've confused to choose N7100 or N7105,because carriers have not provided LTE for Smartphones and Tablets yet,but they launch in 2013,but not sure.
Now,I would know,N7105 Battery Life in 3G carriers is same as N7100?
In addition,I'll keep Note II for two years.
Regards
Its almost the same if your going to use 3g.. but if your carrier will provide lte then better go with the n7105 for future purposes.. both devices have same battery which is 3100mah.. you can go a day or two with minimal usage.. almost 1 day for moderate to heavy usage..

I have confused again because of an idea that stated in http://forum.xda-developers.com/showthread.php?t=1979246
"Here are the facts as i've had both n7100 and n7105.
N7100 gave me 9 to 10 hours on screen battery time almost all the time.
N7105 gives me just over 7 hours. This is 3g only as i'm with 3uk and they only deal with 3g. Their 3g network gives me 19meg download speeds most of the time though.
So a big difference and i actually miss my old n7100 but i'm loving n7105 speeds to. Catch 22 situation. So even with 4g disabled and settings set to 3g only the n7105 radio uses more power. " Lawtq says.
I have been getting 20 mbs down and around 14 mbs up. Anyone getting better then this?

i used to pull down 40-60mbps in the metro atlanta area on my old LTE skyrocket but on my note 2, i've been averaging 15-20mbps. other cities i've traveled to, i was seeing 30+.
i got the skyrocket right at launch and it was samsung's first at&t LTE phone so i'm guessing that the network's bandwidth was hardly being used but with the iphone 5, gs3, and note 1 & 2, there's a lot more congestion which is driving the speeds way down.
I recently had about 45 down and 25 up around Detroit since there's like no one there haha

I had this problem when I first got my NoteII. I was coming from a NON LTE device so when I switched the phone they didn't put me on a LTE plan. If you are in a good area where they have LTE give AT&T a call and make sure you are on a LTE plan. Also if you are on a custom ROM you may have the wrong APN settings.
On LTE I am getting 55 down 35 up all times of day.
