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.

I have a question to everyone. I understand wifi drains less battery than 3g. But what if you are not surfing the web? Which would drain less battery while using the phone but not surfing the web?

Depending on what you're doing...
If you have a strong 3G signal, that's probably your best bet.
If you leave wifi on, it will continually search for available networks, which drains battery. However, if you're somewhere with little or no cell reception, the phone uses more power to search for a cell network.
If you're not actually using any online service, airplane mode is unquestionably best.

Get the smoda widget.
One button, one click. And ur data is off.
Helps w battery. I font know how much. But I ALWAYS download that widget first when I restore my phone
my second widget is from droidmania. Get the wifi one

At home I have weak 3g signal. Overnight, 8 hrs, WIFI conected to home network uses about 6-7% while weak 3g about 40%.
I leave Wifi, 3g, GPS, and bluetooth on all day and use my phone a lot and my battery lasts a whole day. We shouldn't have to **** around with enabling settings anytime we want to use the damn thing. If however you are running low on juice, then at that time you should start turning things off, and lower the screen brightness. Note: the auto brightness setting uses more juice than manual settings.
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

Has anyone managed to find a fix for the cell standby battery drain? As for the people not suffering from it, what rom and kernel are you using?

HyperGalaxy with siyah kernel = the perfect combination....so fast with an abundance of free ram and no signal battery drain

has become much better since i flashed XXALF2 baseband and Franco r2 kernel. Standby (mobile data on) drop was around 4-5% per hour before, now its around 2.5% per hour
Stock LF2 no problem .

Cell standby drain cannot be confirmed by all people and is related to the 3G setup, antennas and location of your provider.
Here the network show a very bad case of hopping when switching to/from IDLE (fast dormancy) which drains the battery in no time.
I'm currently running Juicedefender Ultimate beta with AOSP helper which switches to 2G when the screen is off and no data is transferred. Only issue is that you'll loose connectivity twice (3G->2G and 2G->3G) for a very short time but other than that it seems to work fine and has solved my battery drain problem.
I've been used to switch back to 2G as soon as I don't need 3G/HSPA with my S1 as it's drain is even worse, so it's no big change for me

i conquer on this.
i do use now 2x battery saver, which does the same thing as the juicedefender, but even before that, my battery is very well managed. I would assume that the fact of cell standby being on the top of the list when you havent been using the phone for anything else is logical to be there. That IS what will be draining the battery. I would only see the problem on those handsets that this drain is not within acceptable limits, ie, whatever people have measured as normal drain for these circomstances.
I use juicedefender and with the latest update the battery drain is less than 2% an hour, im happy with that
Ive always found by the the biggest drain in standby being data always being on
That's not totally correct. Data is not what is actually draining your battery (at least it never was for me).
It's 3G not being in IDLE due to sending/receiving data, fast dormancy not being (properly) supported by the network or the network provider having a badly configured/balanced network.
If you switch to 2G, you'll find that your phone can run 2 days with data enabled if not heavily used.
Big exception seems to be Exchange's ActiveSync which is, when an account is configured (whether enabled or not) always top-of-the-list in BetterBatteryStats. But well... Exchange sucks anyway =)
I should have typed 3g data, this single act of letting the 3g connection be managed by juicedefender doubled my battery life
Yeh i have no idea for the technical reason but managing the 3g connection makes a big difference to me
hmm i am not aware of the actual network causing problems with the drain issue during 3g/2g signal. I only knew that when the signal is bad in general or you get no signal at all, then the phone is wasting too much energy trying to log on to a network itself.
i have the 3g swap on my 2x battery saver to rotate every 5min when the screen is off. Its the smallest amount of time you can apply. However i dont know if im the average phone user, as i see here lots of people doing a lot more things with their handsets during a day.
Not so sure about the 3G data thing but I'm only using the phone on wifi with data disabled and I still got the battery drain.

Wifi is another issue, especially when you have the 5Ghz band enabled and your phone hops between both. Try checking if your Wifi's channel is crowded and configuring the router to another less crowded one.
Then force your phone to use either the 5Ghz or 2.4Ghz band depending on your setup; drain should've gone away.

hi.
A few days ago I applied for a data plan.
Until then I was always using 2G network. Now I am using the 3G network while surfig or using the mobile internet. When I finish using it, I use 2G only and disable data.
Since then, I feel my battery is draining almost twice as fast as it was before. I am using the phone and internet exactly as much as I was using before, the only difference is that now I am using the data plan instead of the (very weak) WiFi signal. In battery menu, it appears "cell standby" takes only 4% of the battery life, but the real difference in battery life is very noticeable.
What could cause the difference? And are there any ways to improve battery life with 3G? (Hellybean 15/11 with newest kernel 1.9.5).
Thanks.
*edit* I have also checked, that if I leave the phone on standby with screen off on the 3G network with data on (but no apps that use data), battery level is decreased by roughly 10% every hour. If I use chrome for an hour using 3G connection and screen on half brightness, that would be 35% of battery decrease in an hour.

Try a different ROM? I remember on Hellybean I had really bad battery life. It drained quite fast, especially on browser. BTW, when you got 3G, did you change ROMs or no? Could you also post a battery stats screenshot? Also, data uses much more battery than WiFi. The part where you said it decreases by 10%, that kind of irks me. I would try a different ROM, such as PA 360 which is really good for battery.
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.
