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
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.

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.
what are others thoughts on some of the pros and cons of this update? i'm thinking it will actually save battery to have wifi 'always on' in standby mode rather than repeatedly switching between a on/off state which uses more energy.
It will definitely eat more battery if it's always on under the lockscreen...
Also there is an option to deactivate notifications when new wifi hotspots are around.. if you are about battery life you should deactivate this..

I keep my Wifi always on because it consumes the least battery (vs 3G, LTE, etc).
If I don't play games on my Lumia 920 the battery can last 3 days.
This update is freezing my phone Dunno why but I have tested it. I occasionally get a freeze now and then, but when the keep wifi is on, it is like every couple of hrs... Will test it more though.

Wrong unless your phone is using 5-year old wifi chip.
Correct me if I am wrong, but is the wifi on this phone an on demand type system? From what I see on mine, the wifi unless being used for an actual update or downloading other content goes to sleep when the lock screen is on. It then wakes up if there is an update pushed to it or if something else needs it or of course if you unlock the phone. At least that is the way it appears that mine works.
Also your radio service are going to use much more power than the wifi will as they are higher power transmitters and receivers. There is a reason wifi only works within a few hundred feet and radio works for several miles that is due to the power difference. Of course with more power you get more battery consumption.
In the case of conserving the battery you are better off to use wifi when possible, leave it on and let the phone control it.
In my experience keeping Wifi on permanently lead to a remarkable decrease in battery life. That will depend on where you are though. If I have it sitting at home where it has Wifi connectivity it's likely that I would see better battery life because all actual transfers will happen via Wifi. At work though it can't connect to the Wifi network (private phone, work network) and so I have 3G running anyway while the phone keeps looking for Wifi networks to connect to.
The problem boils down to the fact that while you can switch off Wifi completely because everything can still work using 3G you can't switch off the phone part completely because only data is done over Wifi but you still need the mobile connection to receive calls/SMS.
I would suggest to anyone to simply try out what works better for them. For me it worked best to let Wifi deactivate automatically as it had been the default in WP since WP7 came out.

Maybe Wifi is using less power when you are downloading something and need a lot of data... But when your phone is idle... Constant on Wifi is using far more battery power than 3G that checks for email or weather every 1-2 hours...
Simple enough...if you are consistently in an area with a WiFi signal, leave WiFi "always on"...it will consume less battery. If you're in an area without WiFi signal then turn it off, as searching for a signal will help run your battery down.

Again, simply not true unless you are using a 5-year old phone. Even if you are in an area that has no wifi connection, the extra drain caused by searching for Wi-Fi networks is minimum in a modern OS and modern chipset. I have left all my android phones (the ones that offer Wi-Fi always on feature for a few years now) wifi on all the time. Never have felt much difference vs if I turn wifi off. It annoys me that WP didn't offer this capability for so long.

I tested a lot of phones Android and WP, my experience is that wifi always on is a battery killer... And I'm talking about state of the art hardware... It's just my 2 cent's but i keep it off...
When I don't charge overnight and wifi is always on my battery drops about 40%
with only 3G on about 8-10%
Foxbat: you can leave it any way you want to do it. I'm not saying Microsoft should remove the feature. But in my experience keeping Wifi on kills the battery faster. I tested it for my use case with always on and with Auto and in the end: Auto it was for me.
The best advice you can give to people is: try it out yourself and you will see what works best for you.
A picture or two says it all. See the attached files for my two testing: one with wifi always on for 24-hour and one with Wi-Fi in auto mode for 24-hour:
The right picture shows 0.0%/hour under current discharge rate... pretty impressive

The keyword is 'Current' -- means at that moment. You can derive the same thing from the left in various sections. The key here is that I don't see any discernible difference. Certainly not a battery killer in any sense as you claimed.
If you look at the first 12-hour period of both chart (when the phone is mostly sleep and not used), the result is almost identical. FYI, there are three push emails connected all the time: Hotmail, GMail and Corporate Exchange Email.
Yes the keyword 'Current' -- means at that moment... so your phone is not discharging although your screen is on... Very accurate app...

So, what you saying is that if you have the screen on, you will see your battery percentage drop immediately? You should return your phone if that is the case.
Battery app get its information from the phone OS reporting. If the OS reported the same battery percentage over a short period of time, the discharge rate won't be anything other than zero. That's limitation of the platform, not app.
Instead of criticize the app which is not the point of the post, why don't you post your findings where leave Wi-Fi always on kills your battery?
it' % per hour... and your phone is using currently using 0,0% per hour so if you leave it like that it will run for ever... so where is the mistake?

% per hour is a unit of measurement. It doesn't mean you have to take one hour to measure it in order to claim its rate. That will be average rate on that hour, not current rate which is meant to see what your current usage pattern is. It can't be used to predict your battery life. If you notice that when you take your phone off the charger, it will stay on 100% for quite some time before it starts to drop. Does that mean your phone battery can last forever? Think about it before post these ridiculous statements.
Foxbat - you are trying to tell us how our devices should behave while we are telling you how they actually behave in the real world out there. You can repeat your 5 years story as often as you want to but it clearly doesn't live up to the factual reality we experience every day and I guess after trying it out with different ROMs on the 920 and leaving all other settings the same I know the effect it had pretty well.
Nice to know though that you are having a different experience with different devices.
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.

having battery drain issue, cell standby and over-counted are the main reasons showing in battery stats. how can i get rid of that? after full charge it takes 4 to 5 hours to plug in the charger again.
What are you showing us here? Looks to me like a mostly idle run over about 12 hours, getting roughly 2% per hour drain. That's a little higher than I usually see, but not horrible depending on conditions, especially if the small amount of use you did have was demanding. How much screen on time are you getting out of a full battery run?
I would suggest getting the app betterbatterystats (search xda) to get a better idea of what your issue is, if you actually have one...
Thanks for the reply. I was trying to say that why stand by time consuming that much percentage? Is that normal while data and wifi disabled? And what is that over-counted thing? As you said stand by time is little higher than normal and depends on condition. What kind of condition you're talking about?

I've never run with both data and Wi-Fi turned off (I use data for notifications when idle) so that might be higher than expected idle drain. I typically see 1 - 2% per hour drain in that configuration.
In my experience, you'll need to better narrow down the cause of the drain if you want to fix it. It may be due to weak cell signal (though your screen shot shows what appears to be decent signal), or possibly an app that frequently wakes in the background looking for a network connection. If that is the case, having data and Wi-Fi off may actually hurt your battery performance.
Get the BetterBatteryStats app, it will help you narrow down the cause.
