Battery drains extremely fast because of mobile data

Hi My Friends ,
when I use mobile data networking ( GSM & HSPA ) it drains so fast , cant i just go for edge , there is function for it in iphone , you can turn off or on 3g , is there any function in nexus ?
Because it drains so fast , it drains one percentile per a min , it means that battery drains in 2 hours
Google are you kidding us ?

Its not the data. Its probably what you're doing all together. Actively using data means that 1) the screen is on, which is the biggest drain and 2) the processor is actively running, which is the 2nd biggest drain.
If you want to switch to EDGE only, go to Settings > More... > Mobile networks > "Use only 2G networks"
You'll still get about the same battery drain because the screen will still be on, and the processor will still be working. Any savings you get from slower data will probably be wasted by keeping the screen on longer to complete the task.
I'm assuming you just got the phone? Use it regularly for a few days and stop watching your battery % and you'll be fine. Checking your battery just drains more battery...

Believe me i have been doing nothing , and it drains so much fast compared to HTC Sensation , my gf has a htc sensation and it also use 4g and we dont use it , and the result is HTC drains 2 % and mine ( galaxy nexus ) drains 17 % , we dont have any app under working , believe me this phone is the worst second thing ive ever had ( first one is Iphone 4s )

my LTE nexus battery drains very fast when im at class, and im assuming that because i have a very very weak data signal, to where it doesnt really work at all

Sell it and get the sensation then

Why so resigned? maybe you have an app not playing nice and/or draining more on ICS than in a previous phone. I use my phone for heavy use and sometimes drop about 10-15% in an hour.

u know what , ive been using android for two years ( htc , samsung , lg ) and dont judge me as using this phone efficient , I have knowladge about computer and smartphone almost your age

uninstall all your apps.
check all settings of apps still on the phone.
and see if the battery is better.
often its an app that is using a lot of CPU or Data in the background causing it to never really sleep.
Maybe use CPUSpy to see if its the cpu which is causing the drain.

I have the same problem as therollingstone - I get about 6hrs of screen-on time on Wifi and 2-2.5 hours on data, nothing showing up in Battery stats tho, must have something to do with the network...

Usually its some rouge app running in the background. Management people!

Beastly Galaxy Nexus Prime!

Use wifi whenever possible guys. It's a lot more stable and battery efficient than using mobile data.

Looks like you might want to go back to the drawing board and spend another 2 years trying to learn Android. Surely with your vast knowledge of smartphones and computers you would have figured out the problem by now. Hint: It's you. Damn, well I gave you the answer.
In all seriousness, you are the reason for the problem. You control the apps installed. You control the permissions these apps are allowed to have. It is your job to monitor activity and make sure none are misbehaving. Don't blame Samsung, Google, or anyone else.

Antennas
Wifi
Consumes more energy per time when trasmitting than mobile data, BUT...
Takes less time to transmit data, espescially large files, so it consumes overall less energy.
Wifi scans for a connection and pings the router less often than mobile data, thus consuming less energy at idle
Bluetooth
Consumes a small amount of power at idle to connect to new devices
Scanning for deveices consumes more energy
While connected, very little energy is consumed unless data is transmitted.
GPS
Unless an application specifically invokes the GPS antenna, it will not consume power
Using constant GPS updates (as in Navigation apps) will consume a large amount of power
Some apps will have bugs in them which will keep GPS on indefinitely. Try reinstalling those applications first, then remove if necessary.
Mobile Data
2G antennas consume the LEAST amount of energy at idle, but because they take so long to trasmit data, they can kill your battery.
3G antennas are Ok at idle, but take less time to transmit data, so are the best all around for traveling around metropilitan areas.
4G Antennas are FAST, but consume the most power. Best to leave these off when in transit, and used for stationary, stable connections
All Antennas consume much more power idling in areas of bad reception. So if you know you're going somewhere with poor reception, and don't need data, turn it off until needed (Settings->Wireless&Networks ->More ->Mobile Networks-> "Data Enabled"; "Data Roming" OFF; "Use Only 2G Networks"
This is from the guide to galaxy nexus battery life

I never turn off Wifi, H+, 3G or GPS. Sometimes I forget to turn off Bluetooth after I get out of my car and just leave it on for the heck of it, that while a blue LED is blinking on all the time to notify me Bluetooth is on. It would still last me the 6-8 hours i'm away from home with regular usage of browsing, checking mail, messaging and stuff until I get back, and even then it would still have some power in it. Lasting only two hours means something is wrong and I doubt it's the data networking. Check background services and widgets refresh intervals.

Wasn't trolling, only saying that I think that the data connection is draining battery as I'm getting 6hrs screen time browsing with 50% brightness against 2-2.5hours of data browsing with 25% brightness. So, I think there IS a problem other than the screen that maybe someone has the answer to...

[Q] Constantly in a bad reception zone

When I'm at school (5 days a week) most of my classes are in a building where I do not get a lot of reception, aka, my battery gets killed by the phone to keep up the signal. I do get reception, around 1-2 bars, but that still drains the battery extremely fast. Is there any app or something that I can do to help reduce the amount of battery drain?
I don't want to put the phone into air plane mode because I can still send and receive text messages, but it's just very slow.

Have you tried putting it in cdma only mode?
Sent from my Galaxy Nexus using XDA

You could save a lot of battery life by either connecting to a wifi hotspot (if available) or by turning off background data. The problem your phones having is that it has to turn the gain way up on its cellular radio in order to transmit and receive data. By reducing the amount of background data usage (or off loading it to another network with better signal--i.e. wifi) you'll save a lot of juice.
If you can't do either, there are some things you can do with Tasker to reduce data usage to windows of time instead of always on. May be something to consider.

Give juice defender a try. It used to almost double the battery life on my old X10 when I worked in a building that I could only get 1 bar at best.

[Q] WiFi stays on even in sleep mode!!!

So my stock JB 4.1.1 GSM Nexus is having some issues regarding the wifi, specifically the sleep policy. I have it set to turn off when the phone is sleeping but whenever I go to look at my battery consumption, it shows the wifi as being active all day long. Has anyone else experienced this/ can you reccomend a fix? Thanks!

Same problem here; wifi is always on for me on stock 4.1.1. Anyone have advice?

Not sure why you'd want to turn WiFi off when the screen is off?
But yes, the "advanced" settings on WiFi are a bit finnicky for people. I've noticed that they don't always stick. Just gotta try toggling it a few times over and over.

I know it does because my battery lasts longer when I manually shut off wifi.

Wifi will never consume more battery than the cellular radio.

Wifi consumes more battery idling. 3g consumes more battery surfing.

Over a whole day's use, if you're on WiFi the whole time you'll use less battery then if you're on the mobile network. The idle battery use is higher but your time connected to transfer data (and therefore battery used) is much much lower.

idling in 2g saves allot more battery than Wi-Fi

Turning off the phone is the best battery saver. But everyone knows wifi is the best option if you have it. 3g runs your battery down way faster. Even though most people have known this for yrs, its even in the tips section when you go into your sprint account. "Wifi to save battery" or something like that.

I use juice defender to turn off all radios when the screen is off. WiFi and 3g will pop back on within seconds of the screen being back on. I know not everyone finds juice defender useful, but I love it

[Q] 3G Battery Drain

I have noticed that when I am on 3G, my battery drains very rapidly. Usually like 3% a minute. Is there anyway to fix this, if this is abnormal?

There's no fix to signal related drain. There are only two things that can be fixed really:
1. drain related to apps including unwanted prevention of deep sleep - wakelocks are normal
2. drain related to screen - lower brightness
3g drain is related to signal strength which there is no fix and 3g drains faster than wifi. Also, the older the battery, the less of a charge it can handle. If you're in an exceptionally poor signal area sometimes Verizon can get a signal extender. I haven't dealt with that but I've heard that sometimes happens if signal is bad.

More than likley means that the phone isnt getting a good signal, and is using more battery trying to stay connected. You can try updating to the latest radio, and prl. Has it always done this, or did it just start recently?

Though 3% a minute is really fast. I usually am closer to 1% every minute of two of screen on time depending on signal. Keep in mind battery drain is not linear meaning it may seem to drop off faster at different percentages. I don't know the details of this but this may help:

Thanks tiny and cmlusco. And no cmlusco, it has always done this. I did update my radio to yours (I don't remember which one exactly) and that helped. I'll search how to update prl. And thanks tiny. I'll look into that link.

To update the prl just dial *228 and select option 2.

I feel your pain. I work in an area of Tampa that has zero service and I mean ZERO. My phone tries desperately to cling to a signal and the battery drain is mind blowing. I usually have my phone in airplane mode and switch it off now and then to check for missed calls and what not. One of the roms I was using completely lost 3G and this was while I was at work. I had to change to a different rom after messing around with **778* I couldn't get it back.

It certainly sucks. But i dont really think its Verizons fault. I work on an AirForce Base. Cell phone service is scarce within the whole base. It does seem to be worse for Verizon and Sprint users from the people i had asked about it
Alot of the times my weather app will show totally different locations then where i am, I will pickup the weather forecast for Apollo Beach or Gibsonton(i dont even know where this is)

might be my imagination but i noticed this battery drain using 3G more when i switched to CM10.1(4.21) versus CM10(4.12).
but when on Wifi, my battery usage seems adequate to very good

It is your imagination. ROM has no bearing on 3g drain.

Battery drain....cell standby..

So I have not been getting that great of battery life at all...I've had the phone for 2 weeks so I'm sure it's broken in. Seems like cell standby is eating my battery life , is there any fix for this ?
Edit: seems like the longer my phone is on for the cell standby percentage increases

Cell standby happens when connected to wifi dont think there is a fix

Wifi doesn't affect the cell stanby on my phone. If I turn it to airplane mode and turn the wifi back on cell standby doesn't even show up in my list. It must be some kind of data connection.
