Hei,
With mobile data on, the batter drains like anything.
The 3G coverage in my area is not so good and hence it switches continuously between H, 3G & 2G.
Can this be a reason?
If not this, what else can be a reason?
Is there any app that measures battey drain, mentioning the usage when data is on?
Am using Galaxy S3, GT-I9300.
It is now with Jellybean 4.1.2, which is not yet officially available here in India.

That is a very big battery drain. If it is constantly trying to get one signal or another it will drain the hell out of your battery.

i thought that you are able to check your battery usage under your settings
betterbatterystats would help you find any wakelocks. I have experienced a massive drain with low mobile data signal as well. It was actually more efficient to keep my wifi on all day rather than data. You should also check out juice defender. I mainly use it to automatically turn my wifi/data on and off.

He already stated what is draining the battery. No need to look any further then the signal fluctuations

Hei,
Is there any app which logs the mobile data connection signal strength?

So I just checked my phone here at work and it's been off charger for 2 hours and is already down to 80% battery. The biggest battery drainer is "Cell Standby" since the phone has mostly just been sitting there.
does anyone know why cell standby is draining the battery? I though cell standby would just be maintaining a connection, but is it anything more than that?
Running lean kernal/Das BAMF 1.5
If you select Cell standby it says its "Battery used by cell radio". I believe its the amount of time searching for a signal. Are you in a bad 4g area and your phone is constantly switching between 4g and 3g? It is odd for that to be the biggest battery drain but I guess if you have not had your screen on at all than its not too much of a surprise. Remember that under battery stats all of those percentages and information is based on how much battery you have used so far so it may say 30% of it has been used by the cell standby but that only means that 30% of the 20% battery life you have used.
If you click on cell standby you will see the answer to your battery drain. I bet the without a signal percentage will be up and the cause of the drain.

Its most likely a radio signal issue, as said. What kernel are you on?

Kernel has nothing to do with the radio so that doesnt really matter.

Mine is always number 2, right behind display. However, my time without signal is always 0%. I live in a good 4G area, but do work in an area where I bounce around a lot. In it's infancy I expect LTE to give people fits with this. I don't think it's that out of the ordinary.
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?

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

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.

Hello. I picked up my s3 this morning after having charged that night. I unplugged it at about 1 in the morning, with airplane mode on, bluetooth off, and WiFi connected. When I woke up though at 10, the battery had dropped down to 80 percent while in standby, with no recent apps even running. I'm not sure if this is normal or if it's a battery problem but it's quite annoying, because it drained 20 percent in 9 hours of standby. Any help is appreciated.

I will drain the battery and charge to full again tonight. After I check it in the morning, I'll note what the battery stats say is draining it. I don't want to do it right now because it's been influenced by my usage today.

This looks similar to my problem, and happens only when connected to certain WIFI-networks.

The things that it's say are draining it according to the usage stats are: WiFi, android os, phone idle, and android system.

Hmm. This could be my problem, but I'd need to try out some other WiFi networks to make sure.

Maybe caused by ~LG8 OTA combined with dual-band WiFi network?
I posted this over in another forum, but copying here to see what you all think...
..............
I don't know this for a fact, but I've read some things that lead me to believe the issue may (again, not confirmed), MAY be related to the recent ~LG8 OTA push. The root (no pun intended) cause is related to how the SG3 interacts in 802.11n band Wi-Fi networks that utilize multi-band (i.e. 2.4Ghz combined and 5Ghz running simultaneously).
One of the "features" of ~LG8 was to remove Advanced options for Wi-Fi networks, switching the connectivity logic to "automatic." If a GS3 is in a multi-band 'n' Wi-Fi network, it MAY be switching back and forth between bands, thus chewing up battery without actually pulling any data.
This is unconfirmed, so don't shoot the messenger. Can any of you validate whether or not the Wi-Fi networks where you see excessive drain is indeed a multi-band 'n' network?

This sounds like it could be a possible cause. I'll have to try out some multi band n networks in the next few days or so and see if there's any effect.

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'd like to better understand how your battery is drained based on your location. When I'm at home on wifi and with a strong native signal, my battery life is good. I recently was travelling and found that I would go just a couple hours and I'd go from 100% down to about 60% in a matter of hours with no use!
So what exactly causes such drain? I understand that weak signals and tower switching may drain battery... but is there more to it than that? Is there something I can do to limit battery drain in this situation such as switch to LTE only or CDMA only or Home network only or Roam only, etc?
I have a Sprint Galaxy S6 Edge 64gb.
Thanks!
Welcome to my everyday! My job is in transportation and that's all I do is move around lol
It has to be a location setting tho... Or an app wanting to use location BC I was just on my phone, screen on for 1hr 20min over the last 3hrs traveling and only lost 20%.
