Hello guys,
I've read that whe when I'm at home, it's better to be connected via Wi-Fi instead of 3G (Data Plan) in terms of battery ussage.
Is this true? Wi-fi uses less battery than 3G?
thx
Yes, generally wifi will consume less battery than using data. It also depends on the signal strength. The stronger the signal the better.

Why is it that when I'm on wifi, my battery last longer vs while I'm on 3G?

Wifi uses less power, it's a different frequency, as you're much closer to the wifi device than you would be the 3G cell mast.
plus, 3G need to find signal, when you in a place where 3G signal is weak, it will drain more battery
Use it when you need it...
After serval Test while I was in school and at home I found out:
Edge with Datasync on is the worst! Battery drains in 4 to 5h
Hspda/Hsupa with a good connection is way better. Batterylife 7h
If you just turn if off it saves a lot of energy! Up to 36h
So what I am doing now: I turn the Mobile Network off when I see that little E in the top right corner because the connection is so slow anyway..
Specs of my Phone:
HTC Desire HD with RCMix3D KINGDOM v1.1
1370mAh Battery
For actual data transfer, it depends on how often and how much is being sent.
3G transfers faster, so if you're just going after 1 thing, it can be less draining than 2G, assuming full signal strength on both, because it's in use for less time.
Yes radio and signal strength affect the battery. Some radios work better than others in certain areas thus giving a better signal. If you are right next to a tower your phone will last a while. The phone always tries to get a better signal thus causing drainage.
Thanks dudes, good info

I have a stock Neo and found that battery life is nearly doubled when using 2G as cell standby use drops from 48-50% to 13-15% which I like.
I also have a -89 to -93dBm 10asu signal strength which believe is good.
But when on 2G there is no data connection, so does the Neo not have EDGE also is the phone faulty in respect to 3G data as I can only assume that is the cause of the poor battery.
2G normal uses less power, but if the 3G signal is stronger than the 2G one, I would use 3G as the phone has to use more transmit power to work with a weak signal.

I've got working, but relativly slow 2g GPRS (EDGE?) data transmision. I hate 2g lags (much higher ping) and when it is possible I use 3g or wifi. Maybe your situation is caused by your mobile operator.
I asked the question on sony forum and it appears that all xperia have this problem of no or very poor 2G data connection whereas 3G is there but results in awfully poor battery life.
Just checked about mast location and I'm about approx 700m metres from the the mast.
I have just walked to the mast with the Galaxy W and Neo and both phone signal strength increased the same and at 100m they were -52dBm.
re op your comments still do not explain why the Galaxy W has twice the battery of the Neo when using 3G, my conclusion is that SE are rubbish at 3G.
From my walk I would also say that with a -70dBm that you are 200-300m from a mast, apart from the terraced houses (no high rise/flats ) it is level ground to the mast.
Just to add my phone on GSM only shows gprs not EDGE
Does data connexion drain battery faster ? ( not on 3g, I mean only on 2g because i disable 3g, here in belgium there is only 2g+ so 3g is useless .. )
Thanks !
up No one know ?
Well.. Yes, of course it does.. You may want turn it off when you're not using data.
Yes it does. A constant 2G connection drains much more battery in standby than when it is off. You'll find your battery lasting longer with data turned off. WiFi uses far less power than mobile data.

According to what I've experienced with both my android phone (a SE Xperia X10) and my former maemo phone (Nokia N900) the power consumption while surfing the web on 3G is at least 3 times bigger than the consumption while in a wifi LAN.
I cannot say anything about 2G, because H3G in Italy has no 2G.
It has been documented that using wifi when at home (for example) can conserve battery, however in most cases there is a stable GSM signal. For this reason the phone will not waste a lot of battery trying to connect to the cellular network over and over again. However, I have an unusual situation that I would like advice on. My office has TERRIBLE reception and in fact I constantly lose/regain signal all day long. I believe this contributes to relatively low battery life on my phone(s) that I use. We do have office wifi however, and I am wondering how connecting to it will impact my battery. Would that improve the battery drain, or would it actually make it worse?
I read someplace recently that using Wi-Fi for internet browsing on a cell phone consumes less battery than using 3G. I've been told previously that Wi-Fi, while being a faster connection, also uses more battery. So which is true?

I've noticed when I use wifi I have longer battery life then when I have 3g on

3G consumes a hell lot more power than wifi. My n7.2 has wifi running all the day, and the battery lasts for 1.5 days. My ol' HTC Desire couldn't last 2 hours under 3G.
Wi-Fi uses much less power than 3G. I keep it on 24/7 and there isn't much difference in battery consumption compared to Wi-Fi turned OFF.
