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?

For me it's always been from best to worst
Wifi, 3g, 4g.

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

Same... 4g def kills battery quicker

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.

Eclair: wifi > 3g > 4g*
Froyo: 3g > wifi > 4g*
Gingerbread: 3g > wifi > 4g*
*Was only available when I traveled to a city with it. Closest was ~400+mi away. Lame, I know. Stupid Sprint.

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

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.
Does anyone know much about Sprint's LTE frequency? From what I understand it will operate at the 1900mhz frequency... But what exactly does that mean? Isn't the lower the frequency the the better? Would someone more knowledgeable be able to explain this? TIA!

Wimax is at 2500 mhz ....lte will begin at 1900 and then go to 800 when sprint gets rid of iden. From Nextel .... higher frequency was used because it takes less towers to get coverage but the 2500 doesn't penetrate very good ... the 1900 will work good and get much better later with 800 ...

So what radio is best for data and battery life on the GSM nexus on T-Mobile in the Arizona area?

I'm in az and had T-Mobile they are great out doors but no radio will give you good indoor reception sadly that's why I left T-Mobile

That's not exactly a rule. They do operate on a higher frequency that doesn't penetrate buildings very well, but that doesn't mean that you'll always get bad reception indoors...
OP, you should try some different radios and see what's best for you. Easy to flash and test.
I'm using xxkk6 with T-Mo in WA and its great.

What he said.. I have good luck on UGLA4. NY, NY... mileage will vary.
So Sprint is partially launching its 800MHz network in September. I'm trying to find if it is actually up now. Does anyone know how to view the current frequency the phone is using? Thanks.
Sprint hasn't deployed 800 MHz anywhere on more than a few towers except in the Chicago market. Even in that market, it's unlikely for you to be close to a tower broadcasting that frequency.
But just for reference, dial ##DEBUG#, enter the code 777462, go to the first listing mentioning 1x, and look for the line labeled "Band". Most Sprint service is on band 1. Roaming can be either band 1 or 0. Sprint 800 MHz service is on band 10.
777462 is invalid

The correct unlock code is 777468. (If that is too hard to remember, just enter SPRINT)
##debug# does nothing for me

Correct me if I'm wrong but our phones will never see 800 MHz. The LTE radio it has, isn't built to pick up that frequency.

I believe that is correct for LTE. But the OP is writing about 1x service on 800 MHz.
I've been on 800 mhz here in NW Indiana for the past 2 or 3 weeks. I'm on the southeastern edge of the Chicago market. All the towers in my area are NV complete for 3G according to S4GRU's maps, and I can confirm that since I can see the RRUs mounted behind the antennas. I've seen 800 come and go a couple times, but it's been on solid here at my house for the past couple weeks. I live in the sticks, 5.2 miles exact from the tower (with LoS) i'm connecting to, and my signal went from around -92 to -97 dbm on 1900 to -83 to -88 dbm on 800 mhz. Significant increase.
With CM10.1?

there is no such thing as LTE only, and i doubt it will exist until LTE coverage is more widespread. LTE also runs off CDMA, i don't know the technical information but i don't think it would save any power, compared to using CDMA only. if you want to run LTE just select CDMA / LTE and it will stay on LTE whenever LTE is avail.
if i was to turn my phone on LTE only and do my usual day of driving i would have no signal for 70% of the day, and that is driving around the GTA, which is canada's heaviest population density. so even if u happen to be somewhere where u usually have LTE, this is extremely rare that's why the mode isn't out yet.
cdma / lte priority goes as follow
4g lte - highest priority
4g - 2nd priority
3g - lowest priority
if you are looking to save battery and not performance, use 2g only for extreme battery saving, or CMDA only for moderate battery saving while still having good performance.
.... besides you couldn't make phone calls on lte kinda defeats the purpose of a phone.
