I have a very good 3g signal when I am at home but was wondering what was easier on the battery while at home, 3g or wifi? Thanks

wifi uses less.
my battery life is alot longer on wifi
Thanks for the feedback.

Okay, so WiFi is usually better than 3G when it comes to battery life; but what about WiMax? I don't have a stable signal yet so I can't reliably test the two. What are ya'll experiences (for those within a reliable 4G area)? Better, the same, worse, or a lot worse?

I don't have reliable 4G in my area, but I notice that even turning on the wimax 4G radio dramatically drains my battery. Don't know if its becasue its constantly searching for signal or just becasue the radio is turned on. My 2 cents, but I know it's not very thorough..
Any time you have a radio turned on and do not have a signal it will drain the battery trying to find a signal.
If you go to an area with poor 3g service, your battery will drain crazy.
They are testing 4g in my area, so it is up and down a lot, so I cannot test.
From reading other posts, I believe 4g may take slightly more battery.
Since Froyo has been released, the 4G battery drain isn't nearly as bad as it was on 2.1. I've noticed that the speeds have substantially increased as well as better battery management as well.

Yeah, that's why I wanted to see how things are now. We all know how 4G got slammed by reviewers for killing the battery, but the new radio might have changed that. I'm just curious at how it compares to 3G now under ideal conditions (good signal).
I have full 4G coverage where I live and to be honest when 4G is on, the battery drainage difference is not much, when compared to 3G.
I have 4G in my area as well, but I leave it off because it goes back and forth from being connected to not being connected. I did notice last night that my battery went from 70% to 5% over night... Anyone know what could cause that?

I have the same problem. I'm in the Baltimore area and the 3G/4G switches back and forth. I figured out that when the phone isn't in 4G, it searches for a 4G connection, but you can put it to 3G only (with an app called Phone Info) until Verizon is done with their 4G coverage.
4G uses more power than 3g, which uses more power than wifi.
4g<3g<wifi.
it's significantly worse on 4G, so much so that I have an extended battery and I still don't use it.

there is something wrong with your phone then, maybe it's not sleeping. you should be noticing a huge difference.

Which is better for battery life? O have both good 3g and widow connection are work.
Will using wiring be better for battery or just 3g?

Yo.
3g = 3 - 5 MBits/s
WiFi = 10 - 120MBits/s
And yes we have WiFi N in our phone.
Do the math on how much longer 3g will last.

3G sucks down the most juice. It's just a fact. 2G will drain the battery less and if you have WiFi, your battery life will increase even more. I can leave my phone on overnight with WiFi on while sleeping and it will still have 80% when I wake up (5-6 hours)
Today was the first day I have ran wifi all day and I would say me battery use appears to be about the same as having 3g coverage all day. I would have figured wifi would drain more, but I haven't noticed a difference. Again this is just 1 day experimenting (I have my wifi set to never go to sleep with the screen off too). I have been connected to wifi 90% of the time. As a bonus wifi is a lot faster than the 3g speeds I get, so I think I'm going to leave wifi on all the time now.
Thanks for the opinions guys.

If I leave wifi on at night I lose about 8% or so in ~8hrs.

When I'm on wifi I normally turn all mobile data off. There's a widget that comes with Juice Defender that allows you to do that with one press. You can still get emails and texts, so the only thing you can't do is stuff that requires a cell connection, like Market. It really saves a ton of battery to turn off both 2G and 3G radios.
As others have said, Wifi is better for the battery. If you're connected for most of the day it'll also help to disable the Vibrant's wifi sleep policy.

Stupid question but why? Wouldn't that eat battery? Or does it just male the phone stay on wifi rather than when it sleeps and comes back the wifi doesn't re-iniate?

your logic is wrong.
3G actually uses more battery, so if you turn 3G off, wifi will save your battery.
Anyone think the Wifi version will have better battery life? I keep my 3G version on airplane mode and just use WiFi. The battery life is OK. I am wondering if it is searching for a wireless signal, but this seems impossible to me. The Wifi won;t do this.
THoughts?
What do you consider OK battery life?

How would the WiFi only version get any more/less battery than a 3G version in Airplane mode with just WiFi turned on?

No Idea, But some of the official specs said that battery-life was longer on 3g than wifi.
yeah I get well over 24 hours off of my xoom.

If you didn't run it in airplane mode and it was searching for a signal you would loose battery life. As its in airplane mode, its no different then running the wifi only version.

That may be true for some reason, but the OP is asking if the 3G version in airplane mode using WiFi will have better battery life than the WiFi version. Which makes no sense.
The wifi version is the same hardware except it doesn't have the 3G chip so I'm going to take a wild stab and say they'll have the same battery life if using the same functions.
Just so you know, if you have wifi on all the time, it WILL poll for wireless access points which will eat battery. You should only turn on wifi if you're using wifi. Same with phones.
Thank you all.

Hello fellow xda users. I'd like to ask a question regarding battery usage while on active 3G/3.5G data. To be precise I'm looking into 3G tweaks so it doesn't drain 350-700mA while on 3G data, that kills battery very fast.
It would be great to find a compromise between performance and battery life.
I'm using Typhoon ROM atm. Also, I got very good signal reception, both with GSM/WCDMA
Also, can you report how much juice does your phone drain when browsing(actively using data trasnfer) ? Thanks!
The 3G is very hungry, i din't think anyone would fix this, just use 2G
2G is very slow though.
Shame there are no solutions to this.
3g drain my battery badly too. no solution?
Hey guys, just wondering if anyone has any idea how the battery life on LTE is compared to WCDMA and if there are any ways to try to reduce battery drain from LTE.
Also, would you use LTE/GSM (auto prl) or LTE/CDMA?
Thanks.

Use lte/gsm. There is no noticeable extra battery drain with lte. Just faster data speeds.

No difference. Stock 4.3 with lte is amazing on battery

My best guess is that background data related tasks like syncing finish faster so cpu spends more time in idle and foreground data tasks like webpage loading finish faster so cpu spends more time in min cpu frequency.
By the way, try different lte modems. I had bad battery drain on .33 not because of lte. Battery is excellent for me on .27 and now the hybrid .27/.84 modems.

Hmm, one of the things that affect battery life most is signal strength. If you have poor signal strength, you will generally have poor battery life. I would say this is probably the #2 most important thing after screen on time
Having said that, where I live, I get much stronger HSPA/HSPA+ signals than LTE. At my home, I may hover anywhere from -77 to -89 dBm whereas with LTE it might be between -89 dBm to -95 dbm
In the battery graph, on 3G I get a solid green bar (the best) whereas on LTE I get the slightly yellow-green colour
