Hello there, if you've installed the 4.3 update for the SGS3, you might have noticed the lag on the wake up screen. (When you lock your phone, you press a button to unlock it, and it takes 5-10 seconds for the unlock screen to pop up.) And I'm here, with a fix. This lag has been causd by "deep sleep", and we need to turn it off. But first, install the app below. (Does not require root)
https://play.google.com/store/apps/details?id=otis8.softlocker
After you're done installing, tap the lock once, and you're done. You might check the box if you want this app to automaticly start when you open your phone. Hope that fixes your problem, it fixed my i9300! Have fun

Surely turning off deep sleep is going to have an impact on battery life?
I installed the ADAM Kernel which reduced the lag from deep sleep to around 2 seconds at worst and the battery life is the best ive ever had from the phone.

** Update: I swapped rom and have a battery drain issue, a user reported the had the same thing until a chrome update came in and it had apparently fixed the issue with 4.3...
Not for me i had the update already 2 days ago, i had also flashed ADAM kernel over the new 4.3 rom and that didnt help either.
I cant remember where i read this (ive search but cant find it) but a user said they turned off location services and the battery drain and wake lock issue went away with 4.3...?!?! no one belived them (i really wish i could find the post again)...
Anyway i though what the hell lets give it a go, (note i had already unselected the option to allow google to trawl unsecure wifi connetions regardless if my wifi setting... thanks but no thanks) so rather than initially turn it off i turned off:
"Use wireless networks"
I left the rest of the options on, the phone has GPS so i dont need poor mans GPS....
Guess what since ive made the change 5 hours ago the battery hasn't lost 1% (im on a zero lemon 7000mah cell) so 1% for me is 2-3% on a stock cell, before i made the change i would lose 1 - 2 % per hour with the phone doing nothing at all.
Additionally ive had no wake lag.....
I suggest other user try turning off use wireless networks under location services and see what happens, it shouldn't make a difference but it sure as hell did for me... Such a difference im going to stick with 4.3 instead of downgrading...!!
Just harping back to the ADAM Kernel, i noticed for the short time i was on stock 4.3 MJ9 the phone got hot (cpu) after a period of time, after flashing ADAM no getting hot issues.

Just took my phone off charge a few minutes ago so going to give your suggestions a try, see if the battery drain reduces, it was around 50% in 24 hours with my normal usage, wake up lag from cold was around 2 - 3 seconds so see if that improves, I am on a stock rom, not even got round to rooting it again, yet.
Why don't you just install an app, which keeps the screen always on? I am sure the lag would be gone
Honestly, I don't think it's a general issue. no one has reported this in my thread yet.

I know battery has been diacussed before but i think this isnt normal. I left the office with almost full charge, listened to music on the.way with bluetoith headset for an hour. Got home and browsed for like half an hour. And here is my battery.
3 hours and the phone is almost dead. I have no apps running. I had 3g on when i left the officw and at home i used wifi.
Is this normal or should i take the.phone back for an exchange?
Regardless, i still love the phone.

btw when u return the phone what do u say exactly
Thats ridiculous man. Maybe you're battery is broken.
That said mine has just drained 35% in 3 hours with almost no usage so maybe it is just the phone.
I think there is 100% guaranteed a software problem and we need samsung to fix it.
It says you've had the display on for quite a long time, music needs the display on? Also that wifi sharing is another culprit.
It drained because you had the screen on nearly the entire time not because anything else
Unless thats a case of the 'phone staying awake' bug. You can freeze wifi sharing with titanium backup to save some juice

I too am facing the same issue battery drain from 100% to 60% in a span of 3 hours.
I am having a mediocre usage of battery with touchdown as my mail client talking to my corporate exchange. Still it doesn't warrant a drain of 40% in 3 hours.
I dont have much apps installed. Even with juice defender I am not getting better results.

You could say it's normal because if you haven't yet rooted and frozen the wifi sharing process this is the exact behavior everybody else is also having. A new phone will behave in exactly the same way if it's using the current firmware.
You can do two things.
1. root and freeze the process with titanium backup or similar.
2. wait for the next official samsung firmware which may include a fix.
The rooting process takes about 15 minutes and is not too difficult. You may or may not get in to warranty trouble in case of repair, but as I and several of my friends saw it, there really is no other way unless you want a phone with 3-4 hours of battery compared to the 19-23 hours we all get now after the freeze.
Another thing, it won't matter if wifi is turned on or off, the bug and wifi sharing process will still be there.
You will probably read around the net that several processes has to be frozen, but it really only is the "wifi sharing" one that needs to be frozen for the battery drain issue to go away.
What is the "wifi-sharing"?
Mine GS2 is a bit different from the OP's. Android OS occupied 45% while Display only 19%. And charging time is unusually long. Very long. I plugged my GS2 into PC at 9am with 30% left, and by the time I left work 6pm it only got up to 75% something. That's half a day charge.

I don't really know. But I haven't found a feature not working after the freeze. Even dlna sharing, hotspot etc.. Everything seems to be fine.

Regarding the unusual long charge time, I haven't heard about that before. It takes my phone about 3 hours to fully charge.
I can recommend this application for monitoring if the phone really sleeps when left on the table and which processes uses your juice in general. It's history based and you will be able to figure out a lot of useful stuff with it.

I'm also have a similar problem, but mine was after one hour and an half of web surfing using dolphin HD and wifi... it was full, it's now about 25% remaining... Is it normal that the dolphin browser used 39% of the battery ? It's even more than the display... !
Ps: it's actually really hot on the back of the phone, on the top, just under camera... Normal ? ? ?

Well. When you have rooted your phone, you are able to do a lot of usefull stuff:
-Freeze processes
-Disable the camera shutter sound with a simple property/text file
-Make the middle home screen the real home (like htc sense) with a simple property/text file,
-Replace camera.apk and get higher quality sound in video, actually also higher video bitrate if you want that.
-Replace talk.apk and enable the upcoming google talk with video chat
-Install chainfire3d driver to be able to play tegra2 gpu based games
...and probably a lot more, but above is the only things I've done.
Freezing means : that you lock a process you don't want to run ever. You are also able to "un-freeze" if you decide to revert.
So:
1. you root your phone
2. you install titanium backup or other application that has the "freezing" ability.
3. open the freezing app, go to the process list, find "wifi sharing", press freeze, reboot
Problem solved, "wifi-sharing" will never run again.
You want to revert: Launch titanium, go to process list, find wifi sharing, unfreeze, reboot. Everything back to where you were before.

I really don't think anything matters as I can see you have the wifi-sharing bug.
You must understand, that it's everybody with the current firmware that has this bug. You must either wait or root and freeze.
Sucking up your battery in a couple of hours and making the cpu run at full speed which makes the phone get hot is exactly what this wifi-sharing bug does.
There is absolutely no way you can change anything in the settings or say, not run dolphin browser to fix this problem. You simply have to freeze the process or wait for samsung to fix it. As long as the wifi-sharing process enters your battery usage list you have the firmware that has the problem (and it's more than one) and your doomed until you freeze or upgrade to a future firmware where the bug may be officially fixed.
Just another "wifi-sharing" discussion link:
https://code.google.com/p/android/issues/detail?id=16721
Alright then, it's just that it doesn't seem me to be that much of the battery (~20%...)
I did just freeze that process and will see once my phone is fully charged... Thanks.

oh, was that a constructive comment?
How much percent does your battery go down over night when you sleep? When i first got my tab it literally went down at most 2% and usually it was 1% or none at all.
After using it for 3 months and having a ton of APKs installed on it. I just installed Galaxy task's fat 14 and my tab died while i was sleeping, and I went to bed when it was around 18%
how is everyone's elses battery consumption during the 7 or 8 hrs of sleep?

dude. you answered your question yourself. "After using it for 3 months and having a ton of APKs installed on it." you have apps running in the background and who knows which one is going crazy. i have apps on my tab and at most i'll lose 3% while sleeping for 8-10 hours. you issue has nothing to do with the rom. it has everything to do with whatever app is going haywire.
I wasn't trying to blame it on your rom, its great, I'll investigate the apps/games i installed.
but i was using your task v12 for several weeks without this happening. Maybe something happened to my settings when i upgraded i guess. Thanks.

I know you weren't bro. I was just explaining how with a lot of apps this issue can happen relatively easy. You just gotta try and figure out which app is causing this and then I'm sure you won't have an issue anymore.
go to settings>about>battery use to see which app is using more of the battery.
you can also check to make sure your wifi sleeps when your tablet is off.
I am using task rom also and I don't have any battery issues. Before I go to bed, I always turn wifi off and kill all the apps thats running in the background and my battery never drains more then 3%. I hope this helps.
ot: how long does it take to fully charge the Galaxy Tab? i charged my gt for the first time yesterday and i wondered it took half of the day to reach the 100 percent
Thanks for the tips.
For the official charger that gets bundled i can usually charge fully in what feels like 3 hours.
Via USB on the non official it feels like i need 6 hours

Is there a difference between wifi sleep and OFF? I know there are some market apps that turn the wifi off based on certain conditions but i don't know if that saves more than wifi sleep
I put my tab in "Airplane Mode" when I sleep, and kill all active applications. I found this usually drops 1% or so when sleeping for 8 hours. The airplane mode shuts off all radios.
I have a button on my home screen that toggles the airplane mode, so I just tap that before hitting the power button.
This thread is very useful. I have been noticing a lot of battery drain while the Tab is in sleep mode. Changing the WIFI setting so it was turned off when the Tab screen is off made a big difference.
When I check the battery use info, one of the biggest power users is something called "Mediaserver". Does anyone know what this is. I am not sure if this is something running in the background or just displays as a result of viewing a video recently. If it is a background app, can it be safely disabled? Should it be disabled?
BTW, for those of us who are using Task's ROM, it is really easy to enter airplane mode. Just press the power button to bring up a dialogue box that allows various options including Airplane mode, reboot, recover, etc. This is a very useful feature.
Latest SiyahKernel with stock rooted ICS 4.0.3.
Now, this has happened twice in the last week. I unplug the phone from my charger and place it under my pillow for the alarm to wake me up, and go to sleep. I disable both data and wifi so that twitter won't update and wake me up prematurely. Then, I oversleep about two hours, and what wakes me up is the phone that's EXTREMELY hot. The alarm doesn't go off and the battery is completely drained.
I have no idea what drained the battery and why the phone was that hot (I couldn't hold the phone for more than two seconds before I started experiencing pain). I've tried searching, but there were no topics like this one. So does anyone know how I can fix this?

Thanks for the answer, but even after doing everything there I have the same problem.
A few days ago, I was able to "intercept" the process.
I had just used the phone, and put it away. Then after no more than ten minutes, I noticed it getting extremely hot. When I tried unlocking the screen, the phone had frozen, so I had to pull out the battery to turn it off. When I put the battery back in again and turned it on, the battery level was down from around 80% to around 60%. The battery graph showed like vertical drop, so it was clear that it had happened within those 10 minutes.
Is there really noone who has had this problem before?

Try N.E.A.K ICS kernel. I had some really good results with aokp rom. It's compatible with Samsung rom as well I think. Check it out
Sent from my GT-I9100 using Tapatalk 2 Beta-5
I'd be more worried about it setting my pillow alight
Steps.you could try:
- Wipe all data (Optional maybe an app conflicting with something)
- Update kernel or change rom to CM9 or any other stock
- If none of those work try an different battery
*I believe its an well wakelock had this when i was using siyah 3.1 Rc 1-5*
~Blizz™;
I had roughly the same problem. I did a full wipe and installed a custom from and changed the kernel... everything works perfect then. One of my friends finds taking his battery out every few days works best. Try both and see what results you get.

I would have to guess that it's either the kernel or the battery calibration. Are you using a third party battery? I think with the original samsung batteries, this must not be as much of a problem (I have never owned an original samsung battery for my S2, sadly). I know that with my fake Chinese super-cheap "2150mah" battery, which somehow is small enough to fit in the original cover which makes me think it's more like 1350mah, I have gotten horrible battery drain problems for basically no reason. But, after following the thread where it was explained to charge to 100% and then take the battery out, wait three minutes, and put it back in, I've had the phone stay at 100% for over four hours, with wifi, syncing, and all that turned on.
I should mention that I sometimes also have had this problem where it seems to be charged, then for some reason it drops to 20%.
If your battery is third party, make sure you calibrate it. I've also noticed that the more roms I flash, the worse my battery life is, so I'm trying to resist the temptation of flashing something new every twenty minutes.
Good luck.
/proc/last_kmsg
Use it.
You could try downloading Better Battery Stats and hope to identify the wakelock or app that's draining the battery. If it's not either of those and you haven't always had an issue with it under your pillow, I'd say it's time to try a wipe and new rom and if the problem persists even after that...hardware problem.
Have you been able to leave it under the pillow previously? Part of me is wondering if the overheating itself is affecting the battery and causing it to degrade though I doubt it should happen so quickly and in such an odd fashion as you're experiencing.
After a bit more tinkering and testing, I'm almost 100% certain that it's the kernel, as it was the only thing "constant" in my testing. I reflashed over and over. I also think it has something to do with the wifi, since when wifi's off, my phone is fine and doesn't get touched by the described bug. So right now, I'm waiting for SiyahKernel 3.1 to be released while keeping wifi off.
On the changelog for RC6, it says that the "battery drain issue" is fixed, and on the changelog for 3.1, it says "new wifi drivers", so I'm assuming it'll be ok once the 3.1 is released. Thanks for all your replies and help.

Hello people,
most of the time, during the night, I left my phone in Airplane mode and usually loose around 2% (~7 hours).
But since some weeks, I find my battery lose approx. 1% per hour...and I don't know why.
I tried to find wakelocks but nothing really evident -> http://forum.xda-developers.com/showpost.php?p=42248819&postcount=14809
So I'm wondering, if like me you're using sometimes the Airplane Mode, how much battery are you losing per hour ?
Thank you
I can use AP for about 10 hours (never tested longer), without losing a single percentage. Did you check for wakelocks?
1% if I hit snooze on the alarm 5-6 times over half an hour, 0% if I switch the alarm off as soon as it goes off (This is over 8-10 hrs).
Edit - Battery could be on the way out if you've had the phone for a while.

As you can see here there's nothing really obvious, for my part I do not see wakelocks
However, in normal usage, when I make some calls, I can see the battery draining much more than before.
I had some doubt about the open source RIL implemented in CM but I recently flashed an older nightlies (prior to open source RIL commits) and get the same drain in Airplane mode...around 1% per hour.
Anyway the small draining you get with your respective is showing that there's really something wrong on my phone.
The question is: What's wrong ?!
Thank you for replying
Quite weird, because I can't detect any bad wakelocks in that post either.. Maybe try another rom (Samsung based) to test it out? I don't use CM anymore so I can't say anything about it, but Samsung-based roms work really good.
No, you did not mention a new battery in your OP. This is the first time you've mentioned it.

My bad, sorry. I was sure to have mentioned that my battery was new. That being said, now you know that I changed the battery
Yesterday, I made a full wipe (again) ...factory reset, format /system, run GS2ROMNuke script then flashed the latest CM nightly.
After the first boot I just configured the Wi-Fi access point, my mail account and disabled location services. Nothing more than CM installed.
Then I waited the phone was in full charge (~2 hours),then disabled sync, Wi-Fi, switch in airplane mode and unplugged the power supply.
The phone has been left in this state for ~11 hours, believe me, the phone lose around 11% of battery.
I'm losing it
Anyone with an advice ?
Could it be due to the phone itself, some hardware faulty component ?

Well i just got the LG G3 and am using it on GSM.
prior to using i rooted ,TWRP and loaded jasmine 4.0 , also put in skydragon kernel 2.9.4 s 3.0 had crazy boot times.
I am trying to get the max out of the phone what ive noticed is that the phone just doesn't wanna deep sleep.
I have greenify , xposed (amplify) and noticed the issue of battery being drained when idle , i went to sleep and saw it was at 50% , woke up to 10% battery, my older phones never dropped more than 2% overnight,
To investigate loaded BBS and wakelock detector , nothing that pops up out of the ordinary
So my question is what do you guys do to max the battery outta this , what can i do ? i dont really see any apps causing it to wakeup . suggestions or any would be appreciated
any other stock rom also if you could suggest for battery life ? ive heard good about cloudy 1.2 as well.
I have really gotten great battery life out of sky dragon along with the 3.0.2 SD kernel (kernel is in the orig Dev section). Along with amplify ad greenify.

Are you connected to WiFi when your phone won't deep sleep?
I work from home, so my phone spends 90% of its time on WiFi - I was getting terrible battery drain and only 50% deep sleep on a good day. One day, I left the house and noticed great battery life and plenty of deep sleep on a 4G connection (which is the opposite of what I expected).
After trying nearly everything, I discovered the fix was as a simple as turning on the "Battery Saving for WiFi" setting under Settings -> Wi-Fi -> Advanced Wi-Fi". I've been getting great battery life and deep sleep times when I'm at home now.
Give it a shot and see if it solves your issue.
Also, ever since daylight savings time went into effect, I noticed both my phone and my wife's phone keep randomly changing time zone for no reason. Looks like the phone is struggling to automatically detect the time zone from the carrier and causing battery drain as a result. I disabled the setting to automatically detect the time zone (and manually set it for PDT) and the battery drain stopped on both of our devices.

Are you connected to WiFi when your phone won't deep sleep?
I work from home, so my phone spends 90% of its time on WiFi - I was getting terrible battery drain and only 50% deep sleep on a good day. One day, I left the house and noticed great battery life and plenty of deep sleep on a 4G connection (which is the opposite of what I expected).
After trying nearly everything, I discovered the fix was as a simple as turning on the "Battery Saving for WiFi" setting under Settings -> Wi-Fi -> Advanced Wi-Fi". I've been getting great battery life and deep sleep times when I'm at home now.
Give it a shot and see if it solves your issue.
Also, ever since daylight savings time went into effect, I noticed both my phone and my wife's phone keep randomly changing time zone for no reason. Looks like the phone is struggling to automatically detect the time zone from the carrier and causing battery drain as a result. I disabled the setting to automatically detect the time zone (and manually set it for PDT) and the battery drain stopped on both of our devices. Could be unique to my area but may be something to try as well.

I thought the same as well which is why I discounted this as being a cause for 4 months....I have 15 other android devices and none have exhibited this behavior so I was surprised that such a trivial setting could have had this impact.
To answer your question, I am currently running:
- BeanTowns stock 11B ROM
- SkyDragon 2.9.7 kernel
- Xposed installed with Disabled Services running
- Selected stock apps/services disabled
I don't use greenify/amplify (don't see the need as my average daily drop is anywhere from 1.6% - 2.4%/hour with moderate use).
