Hello Everyone.
There is a battery drain issue in in cell standby and I think I just solved the issue. Let me go back to when I last experienced such an issue. It was when I flashed a ROM for my SGS1 Captivate called Cognition. There was a bug that left wifi not only on but it was active during sleep mode.
http://forum.xda-developers.com/showthread.php?p=12294219
It was later solved by the Dev and the draining went away.
What is different here is that the SGS3 only has this bug when wifi is on. Look at my battery charts when I have wifi on and wifi off. The red area shows the slope with wifi and the blue area shows it without wifi. This is during standby times.
So is this due to the wifi dual banding just taking up more battery? Or is the phone not properly tuning the wifi down in standby? Solving this issue is out of my hands now and I will have to hand this over to someone else.
For now, change your wi-fi sleep policy to shut off when in sleep mode.
EDIT:
So I think i figured out why the wakelocks are happening. Other people have the problem with dynamic IP addresses.

I don't know why these other fanboy war threads are bumping and so popular but a serious problem doesn't even get a response or a second look. Does anyone else have any comments on how we can get this fix? We need Samsung to fix this problem too.
I will make this post for two reasons;
To bump the topic
To say that i would also like this "bug" to be solved

hi slim,
I agree with you here as well. However I've not noticed any battery drain. I've got about 35% left after good full day of use.

I'm experiencing some kind of battery drain too with sgs3, but mine it's not wifi related. I have as first voice in battery stats page Cellular Standby. I mean, it's almost impossible it drains more then the screen!
Anyway, giving a look at your screenshot, I can clearly see some areas you didn't red boxed when wifi was on, screen was off but battery drain was not terrible at all.
How do you explain them?!

Yeah, I mean my battery life is still good, but I know it can be better. Now that I made it turn wifi off when it's asleep the battery life, the slope you can see there in blue, is a lot better. It's not so slanted and draining as quickly.
A lot of other people that complained about bad battery life I noticed the same trend, it's their wi-fi also. If you notice the long blue line on the bottom, that's when wi-fi is active and those extreme slopes have to be caused by wifi. Cell standby shouldn't be draining the battery more than the screen I don't think.
It's either wi-fi, the radio or both.

I don't know, I guess that is when the wifi properly shuts itself off.
When I look at my screen while I'm not doing anything at all I can see the orange arrow on the wifi on, and it stays on even though I'm not using the internet or anything. What can that mean? Is the orange arrow "uploading" or "downloading?"
EDIT: It's downloading. And I set the wifi to shut off if the screen shuts off. The Wifi sometimes shuts off. But right now it refuses to turn off even in sleep! And the orange arrow is lit up!
How do you get the wifi to shut off when the screen shuts off?

It's there in advanced wifi settings.
Did any of you people tried flashing different modems to resolve this?

If you turn off the wifi then wont it just use the normal data connection and so use more battery? I was led to believe that using wifi was less demanding than say 3g.

Yes that is correct, but read my OP and the thread I posted. A wifi bug is the wifi not powering down in sleep mode. It stays on at full power during sleep and drains your phone.

I tried a couple of modems, but in vain. Cell Standby is always much too high. Wifi is beyond good and evil.
I would by now also lean towards a bug. Unfortunately I'm not a Android dev. My knowledge ends at developing apps.
I am satisfied with mine
ive noticed smth:
with Droidwall blocking everything -> still wlan sends smth & causes traffic
hows that possible? u guys can experience the same?
under 3g/edge and droidwall everything blocked: no traffic anymore -> everything is ok!
Have any of you guys tried easy battery saver? One of the features is to disable radios when screen is off. I wonder if it is more successful in doing this than the built in setting.
I got the same cell standby problem so I went ahead and flashed Omega ROM, yesterday was my first day full with that ROM and the result was quite good. I ended up with about 45% battery after about 15-16 hours. Well I'm on wifi for like 3-4 hours though.
Drain caused by exchange sync process. Kill this process and see how battery life will change. Sorry for my english.
Curious, which F/W are you on? I was getting oddball WIFI battery drain using an older LE9 insecure kernel to root at first (WIFI would actually shut off and come back on after coming out of idle... even though I had it set to "always on.")
Completely went away after I flashed back the stock LEF kernel that my phone shipped with.
For reference below, no drain issues during idle with WIFI left "always on."
Hello all, so I've done some Google searching to see what is causing this awful Wakelock on my device and I can't figure it out. Asking help from you all. It's called "SmartFaceService" and basically is responsible for my battery draining 40% while I was asleep. Picture is attached. Any ideas?

All smart screen features. sucks we can't use it without it draining the battery
could autokill on screen off
Just as an update, I installed the factory image and did a firmware initialization on kies and the wakelock hasn't been a problem. Not sure what to make of that but - I didn't know how else to deal with it since it was destroying my battery life
keep the screen on if you look at the phone: smart face

The latest update has improved battery life...

1 install Android Assistant, search for it on Google play
2 check what apps are using the most Cpu time
3 decide what you need and what you can uninstall (careful).
Mind you, some apps may not appear in the list and be often using cpu time anyway.
In addition, try the app 'Greenify', it can help a lot in saving cpu time and energy, if you learn how to.use it.
Also (only for rooted devices) use Autorun manager or a similar app to select apps you want to prevent from starting at boot.
Hi
I will try tht thanks.
When i look with gsam the android(os kernel) is at 82%!
i think that causes the battery drain right now but dont know how to fix it
Hello

I had this same issue. Mine was overheating when i used any app and sucking up battery life like crazy. Yesterday I did a factory reset, reloaded my apps, and installed the latest firmware update (NF6). So far everything seems to be back to normal. No more overheating and no extreme battery use/drain.
oh ok.
I only have the battery drain but no overheating yet
But isnt it to quick to putt it back in factory reset since i only have it for like 3 days
Hey there!
I flashed the official Lollipop (Germany) rom that is posted in the Note 4 General forum two days ago without doing a factory reset. Right now, I am experiencing horrible battery life. GSAM reports that the phone radio is using 35% of the battery life. I also see the 4G icon blinking every few seconds, indicating that mobile data is being used. How can I solve this? My battery life was perfect before flashing Lollipop...
Many thanks in advance!
Screenshot just in case:
Maybe you should try a factory reset.
Although I updated without resetting and one of my friends did a full wipe before and after, and we both see a decrease in battery life. Nothing too horrible, but noticeable. So I think it's just Lollipop. After all, even the Nexus devices have been having battery issues with it.
See if a factory reset helps you, worth a shot.

Thanks for your advice. I will be sure to give it a shot. A decrease in battery life is pretty bad if you ask me. I thought Project Volta was supposed to improve battery life, not decrease it. And definitely not as much as is happening to me. By the way, the phone radio is still constantly active. I hope a fix will be out soon.
Can you check your Power Saving menu? I have similar problems with all apps that are using mobile data. Their Total connection time is really long even though I have used them for a few minutes.

Unfortunately a factory reset didn't help. My battery is still draining way too fast.. I can get around three and a half ours screen on time. Previously that was around five hours. I will check the total connection time later on when my battery has drained a bit!
Horrible battery drain in my handset, too. 910F model with German rom.
Flash echoe lollipop rom.waaaay better then stock.no more battery drain for me and much faster!
Formating cache partition helped me to get rid of the battery drain.

That sucks. It seems like this is a very serious bug in Lollipop. You'd think Google would have it figured out in 5.0.1 but that doesn't seem the case. Very annoyed by this.

here the same battery drain of facebook after lollipop upgrade (germany)
when i unplug wifi it starst keep stay connected to facebook and it grows even bigger than screen battery consumption.
heve you fixed it?
thanks!
I found WiFi to be the culprit for the rapid battery drain on Lollipop. Check out the following posts with my observations so far:
iridaki said:
After updating to Lollipop, I found that the phone behaves very differently. I have high "stay awake" times, caused by Android OS, even on Ultra Power Saving Mode. However, screen on time is still close to 4 hours, which is what I was getting on KK with my usage.
Before people jump in and say I need go factory reset, no I don't, there's another Note 4 in my home right now that was wiped before and after the update and shows the same symptoms.
Also I did install Gsam, but I'm not rooted, so it didn't give me more information than the stock battery stats page.

iridaki said:
UPDATE: I think I found the culprit. It's the WiFi. What I did today was charge my phone to 100%, switch WiFi off, disconnect from the charger and reboot. Then went about using it as usual, only I didn't turn WiFi on at all, not even for a second (weirdly enough, the battery stats report WiFi being on briefly at times, but that's another Lollipop bug).
The results were a big increase of SOT (+1 hour, see my previous post for comparison), no more permanent wakelock and increased standby time.
My findings are consistent with reports from Nexus users, claiming WiFi on Lollipop is a battery killer, even on 5.0.1, which was supposed to be an update to fix said issue.
Now, not turning on the WiFi is not really a viable solution for me, as I don't have an unlimited data plan, so I sure hope Samsung will fix this problem soon.

Below are screenshots showing battery behaviour with WiFi on (first 3 images) and with WiFi off.
It's important to point out that simply turning WiFi off doesn't appear to bring battery drain back to normal.
Turning WiFi off and rebooting fixes the issue, so long as you don't turn WiFi on again.

LOLLIPOP
I've started to have very poor battery life 7 days after installing the DBT lollipop. 60% after 4 hrs use today. It was good at first but has been getting worse by the day. Something was making the phone get hot just now so restarted and its cool shortly afterwards. However I cannot identfy what it was causing the overheating.
Is it worth trying to wipe the cache? I did a factory reset after the install as it was boot looping. I really do not want to reset it weekly! Google is crap at backing up all the apps - 160 out of 196 were reinstalled after the factory restart. Very poor.
Hey guys. First proper charge from around 3% too 100% and I'm getting battery drain already, I thought this issue was resolved in lollipop? Not the mention the emense heat that comes off of this device
Check out the picture and get back to me. Thanks.

Same thing is happening to me... I don't find that the drain is really so bad, as I still get pretty great battery life, but does appear that this issue is still present in lollipop. Seems pretty wide spread among Android users.
I had an iphone for about 5 months. Went back to android and the problem still persists I got 3.5 hours of screen on time yesterday. Take a look at this
Also getting battery drain, the main offender seems to be the "mobile standby" which is always around 50-65% for me.

I think this was an error in reporting in the stock firmware, I haven't had a problem with the battery, in fact it's been really good. Since updating to B132 (GRA-L09) the battery usage seems to be reported correctly.
Interesting, I'm not sure what the normal drain should be then. My HTC One had a pretty good battery life, but it seems with this phone the battery drains quite fast when I'm using Chrome and WhatsApp etc. The power saver reports Chrome uses a max of around 10% but the rest use very little %, yet it seems I'm using around 30-40% of the battery in around half an hour.
Do you think using a custom rom (when they become available) would be any different?
Not sure if a custom rom would help. Are you rooted? If so you should have a look at betterbatterystats which should show you what's using up the battery.
When I'm mostly on wifi I can get 5 hours of screen time with 32+ hours running time.
i have the same problem with the "mobile standby" batery drain
i did a clear data/cache then factory reset, and now it's ok
androyd system still drain batery pretty much

Was going to wait for a few roms to be released before rooting, but the battery life seems so poor I think I'll do it just to find out.
I've had the same Problem with the battery drain and analysed this with the Wakelock Detektor (needs root). Cause was the "NlpWakeLock" thats part of the Google Services. Then I disable the Google Location History everything went well. They are a lot of of useres, who have the same problem. The only real solution (If you want to use the Location history) is a Xposed module for that you need a working Xposed framework.
I have now disabled Google location history, hopefully this fixes the problem for me too.
