Hi, I have a limited data plan. I noticed since I bought the phone is consuming Cellular data even if I don't turn it on.
Like 1mb per day in minimum. But the problem, I think, is the consumption of battery because of that problem... the phone is new and some say that the battery takes a few cycles to adjust...
but anyone experienced this issue? or it's something active by default that does this?
Consider it as date time exchange from server.
You will definitely notice that 1 mb because on signal network phone makes data exchange like automatic time update etc.

But before when I didn't have data plan it wasted money. The mobile carrier told me that I had the mobile data on, which I didn't had.
Well consider as your bad luck then..

Hi,
I am on an unlimited plan with my mobile service provider.
Which do you'll recommend that I use Wifi or 3G? When am at home, I could switch off my apn and switch to wifi, but I need to know which you'll recommend.
I don't really use the mobile to browse or do anything special ... just that the mobile does its normal check (syncs my email through exchange and Gmail). Both exchange and Gmail mails don't really pull a whole lot of data so efficiency wise, I really don't care.
What I really need to know is which one uses more battery? If wifi uses more battery, I'll just use the 3G or otherwise.
Thanks for any input.
First off, idling on WiFi uses more battery than idling on 3G. Are you sure you have completely unlimited data though? For example, T-Mobile claims to have unlimited data and (which is true, they do BUT) they severely limit your data speeds after 5GB of data. If you're just idling getting emails and push notifications then you'll never hit 5GB (hell, I'm constantly on XDA on my phone and my wife is constantly on facebook and FML and we haven't even broken 2GB yet).

I have found this to be 100% the opposite with both my Nexus One and my Nexus S. I am running 3x push email accounts and I'll lose ~ 1% / hr on wifi and just over 2% / hr on 3G when the phone is sleeping (and i am sleeping). I saw the same behavior on the mt4g I had for a few weeks (although it sucked a bit more on 3G than 2%).
On every one of my previous win mo handsets (6800, TP, TP2) wifi was a battery killer, but I can say that on my 3 android handsets (as well as the other 2 at our company) wifi uses considerable less battery than the 3G radio.
Ive been usng my phone for quite a long time without Wifi but ive noticed that recently, after I installed Eaglesblood (dont think the rom/its kernel made much of a difference) the battery life with wifi ON has been draining much slower than without wifi and the use of data only. I dont understand because ive been using it constantly and it has been yanking in data constantly but draining much slower. Normally data on lasts me about 11 hrs on a good day. I was home all day, so with wifi on, my batter is at 30% left with 14 hrs of usage now.. Can anyone explain to me why this is happening because I wud much rather have a slower drain on 3g data than wifi (Im not always home and data is used much more extensively in updating).
If you're using wifi, you're generally in good range and have an easy connection.
If you're using data, things like buildings and movement can interfere with your connection, meaning it has to do more "searching" for the proper signal. Even if your bars tell you that you have a good connection, all that tells you is the total amount of signal, not the available amount to you (so sometimes even if you have full bars it needs to search for a good connection).
Correct, if you're on radio (2g/3g/4g), the phone is constantly searching for a signal and will thus spend more battery.
Hence why people say, turn off your radios (airplane mode) when you're in an area with no signal...like out in the boonies, because it will spend time searching for a signal that's nonexistent.
Some people say that Wifi uses up more power than data because it has faster data transfer speeds, but that clearly isn't the truth.

Who said that? I've never heard it. Wi-Fi is known to use less batttery since day 1, clear and simple.
Sup' XDA forum !
So, I recently installed CM9 on my HTC phone (2 weeks ago).
Since 5 days my battery life is very low.
For exemple today my screen was on around 30 minutes (without the battery loader) and the battery is already very low.
Here you have 3 screenshots of the battery utilisation :

You can see that the screen seems to be the mainly problem of battery drain, but on the second screen as I said before my screen was turn only 30 minutes a day ! It can't drain 60% of my battery only with the screen on 30 minutes !
By the way the phone is many times in activity ("awake") and I don't know why.
I turned off the Wi-Fi connexion but that does not change anything.
I don't know what "mobile standby" is corresponding to, this is totally abstract...phone idle and Google services too...
I disabled the e-mail synchronisation, but same problem.
Anybody can help me please ?
Sorry if I commited mistakes in my sentences.
Do you have "Restrict background data" enabled?
Also are you using any management applications?
Regardless CM9 with its standard kernel is known to be juice hungry. I'm currently back on CM9, now using the "Stable" release. Still testing battery life. But I can tell you I've underclocked the "off screen" processing, and also using "medium" auto-kill settings in System Tuner, and my phone did not drop a single % over 8 hours of inactivity (sleeping) but quickly dropped 5% when I used the phone in the morning.

There is a data connexion limit with my mobile phone operator (250Mo a month) and I reached the limit some days ago.
I don't know if there is a connexion between my problem and that but if I reached the limit there's no more data.
I have a task killer to check if there's something that should not run but nothing special. I had no problem before I don't know why now there is one.
Anyway I restricted the background data I'll give you a feedback at the end of the day or tomorrow.
(Again, sorry if my sentences are some times confused.)

Regardless of whether you have data with your carrier or not, having background data 'on' will use more battery, as the mobile data service on your phone stays somewhat open.
In saying this though, it doesn't explain why you are getting bad battery life all of a sudden.
Have you recently moved house? To an area of bad reception? A phone that is constantly trying to find signal will drain the battery much faster, then a phone with full signal.
Have you installed any new apps recently? Might be some juice hungry new app running in the background?
Normally if this happens all of a sudden, it's generally for a valid reason.

I disabled background data and I had no problems anymore.
I recieved my monthly 250 Mo data yesterday, re-enabled the background data and everything works fine.
Thanks!
Here is my questions :
No doubt , when using phone for data , wifi is more battery friendly.
But what about just staying in sleep , not using it , having skype and whattsup opened just in case someone contacts me...
So , in Idle , wich one is battery friendly ?
In my opinion it is the mobile data, because the modem is always opened , so it does not consumes extra battery .
But if you keep your phone on idel connected on wifi , u`ll have both data modem opened (for incoming calls) and the wifi modem opened...
2 hardware pieces that eats battery....
So in my opinion just staying on mobile data in idle saves more battery.
i`m expecting more opinions...

I agree, but IMO, when I want to save more battery, I'll just switch to "2G Only" mode, that'll make differences
and if I need connection, I simply just switch back to 3G
WiFi eats far, FAR more battery than 3/4G.
If you really want to spare your battery, you could just turn Mobile Data and WiFi off, and manually turn on Mobile Data for a few seconds every hour. Whatsapp delivers messages the second the data connection is made. That's how I do it, anyway.
There's probably even apps that allow you to set an automated task to turn on the data and turn it off again a minute later every set ammount of minutes. I've never looking into it though.
What type of phone do you have? With a CDMA phone, if you are not close to a cell tower, the phone will put more power into the antenna in order to try to get a signal. This is true with all CDMA phones, so you may want to take that into consideration. Having an established connection consumes far less battery than having a wavering signal, so I would suggest leaving it on whichever you have the strongest signal, being wi-fi or the mobile network.
Personal experience with an iphone 4s, Wifi tends to drain more battery from my phone.
However, I feel both Wifi and 3g is a battery killer,
if I turn those 2 off, my iphone 4s could stay for 2 whole days on regular usage.
With either of them turned on, it could barely last a full day.
I would agree with the others. Wifi for data is indeed friendlier, but when it comes to sleep mode, mobile network is the way to go.
I don't know if it is because of the reason you mentioned about the 2 hardware pieces, but it sounds right..
Hey guys just a quick question. I already get phenomenal idle drain. I don't drop a single percent overnight in an 8 hr period. Couldn't be happier. I also have no wakelock issues However I want to help battery life while not idle.
So I created a tasker profile that enables data when only in apps that need it like Tapatalk. Then when I exit that app (screen still on) or turn the screen off data shuts off.
My question is if I'm going more harm then good with the constant data toggling. I know it's probably subjective to how much I use these data apps so data gets toggled. Is there a way to test this myself?
Not worth your effort. Don't try to micromanage too much.
thats right, enjoy your device instead.
OK thanks guys

How do you get this?
I would just say to one day use your data toggle, and don't the next day if you're curious. I'm usually curious about these things too. I set my Tasker up so it switches to 3G when I'm connected to my work's wifi. My whole work's area has very strong 3G and very weak LTE so I have bad signal because the phone keeps trying to connect to the LTE network. However, my work's wifi is also not very stable and it keeps disconnected which leads my phone to constantly toggle between 3G and LTE. I'm not sure if this affects battery drain but it felt a bit like a drain. I just ended up manually toggling. But I'm usually curious which what drains the battery more. Since your data would be off when the screen is off and if you're not using wifi you should get very good standby time.
