As you can see I have a few spots where my screen is off for hours at a time but the phone still wakes up. I'm trying desperately to find out what the cause is as I have basically no syncing going on. No news, no weather, nothing.
So if anyone out there has PERFECT wake locks where the only time their phone is awake is when the screen is on, please post up! But I'd like to see everyone's wake locks anyways, to compare and contrast.
Thanks!
Mine appears a little worse than yours

Yeah yours looks a lot worse than mine.
Anyone else wanna post? Looking for some more wake lock screens please.

The phone it self will always wake up due to other functions, not necessarily network data sync.
For example, Alarms, or Calendar Reminders, Or Weather service (and various "smart" features in Google Now) . or IM programs (WeChat/WhatsApp/GTalk etc), or even Google Playstore/Music (for example if there are new app updates or music added to your library etc)
If you make all those gone, what is the point to have a smartphone anyway.....
Yeah, anything that syncs will be a wakelock. I have 3 email accounts syncing and one of them is high volume. I get text messages a lot too.

Yeah alarms seem to be one of my highest wakelocks at the moment. But as for the rest of that stuff, I don't need any of it to sync. Weather updates when I wake up my phone, so it's pointless to have it sync at random hours in the middle of the night. And I don't use calendars at all so that's wasted wakelocks there too.
Just because I don't use these sync events doesn't mean there's no point in having this phone. It's amazing as a pocket web browser, tool to research things on the fly, and media player. Not to mention I just love being able to hook this thing up to a dock and use it as a portable computer. There are other reasons to own a smartphone like this other than just the basic social fads.
Looking at everyone else's wakelocks though I'm pretty happy with mine. It wakes up very rarely and it's not as huge an issue as I once thought it was. Anyways thanks guys.

I think there are several things that can help after some testing. Seems the 'Smart stay', 'Smart Rotation' and 'S Pen Keeper' all play a part in the wakelock. Try disabling those and see how your results fare after that.

First of all I've search through the forums, google, samsung support and even friends with the SGS2 as well yet I keep having the same problem.
No matter what I do, play games or just leave it on standby my battery dies in 5-6 hours.
I'm on Android stock 2.3.4 non-rooted, Baseband version I9100UHK1 kernel version [email protected] #2 Build Number GINGERBREAD.UHKI2
Brightness always at minimun, I changed TouchWiz to go launcher with a minimal setup where my icons are just white text and my background is quite dark, I don't run any app like twitter or facebook or anything like that, just pulse but i have only 3 feeds on it and they have news pushed every 5-6 hours.
Also I have widget locker, and the app i semi-use a lot is WhatsApp.
The thing is I've hear the battery isn't the best but most of the people I know get at least 8 hours with it and is driving me crazy since I go to work around 7 and when I'm going to lunch I'm hitting 15%...
I can provide any info required but I would really like some help here, I want to know if maybe I had a defective battery or something or if there is something wrong with my phone.
Although If I'm on a WIFI the phone can last up to 10 hours, so perhaps I was thinking i was having a signal problem so I switched my network mode from AUTO to WCDMA only since I like to use the 3.5G network since in my country the 3G network barely reaches 256K...
I also have widget locker.
Well that's about much the info I think I can give so far... tomorrow I'll be posting a picture around lunch with the battery usage so you can see how fast it drops, it's amazing it takes me 7 minutes to get to the office and in those 7 minutes I would go from 100% to 97% easy...
Post a screenshot of your battery usage.
Sounds like an app is keeping your phone from entering deep sleep, try downloading betterbatterystats from here http://forum.xda-developers.com/showthread.php?t=1179809&highlight=better+battery+stats to see if you can track down the offending app. There is plenty of explanation in the thread that should help you locate the source of the problem.
Ill be posting a battery usage screenshot tomorrow and getting that BetterBatteryMonitor since today I've been with the wifi all day.

Sent from my GT-I9100 using XDA App
im not too great with BBS stats. What I do know however is that using the phone with no apps installed, then installing each app u like one by one always helps. As someone explained earlier your phone is awake a hell of alot more than your screen on time. Im currently on 27 hours with 3 hours screen on time and my batt is still on 35% so thats an indication of the battery life you should be able to get with the stock battery.
Your alarm manager is draining a lot of battery though, if i'm not mistaken, the alarm manager has something to do with apps that sync, so something that syncs is more than likely draining your battery. Just noticed you have liveprofile. I must say Liveprofile DRAINED THE HELL out of my battery, it doesn't happen to everyone but once I uninstalled liveprofile my battery issues went away real quick
Uninstall whatsapp and see how your battery is then.
Whenever I install one of those style of apps my battery life drops to what you have now. Uninstall and I gain a couple of hours all around.
Whatsapp shouldn't cause issues, I have used it since day one and most people report it to be fine. Liveprofile however just runs non stop
Are you using VoIP? If yes, try to disable sip registration. When I had it enabled, my battery would drop around 5% an hour on standby but now it drops 1% every 3 hours or something. Today I'm 12 hours on battery with a couple of phone calls, 20-30 minutes gaming, an hour of internet browsing, some music and wifi on for 5 hours and I'm still on 81%. I use Checkrom 3.1.1 with Speedmod kernel and ondemand governor with no underclock or undervolt. Brightness at 40%, a gmail account with push enabled and another e-mail account syncing every hour.
You should find out what app wakes up your phone so often and uninstall it. It may help if you flash another kernel too.
Ive always had a problem with whatsapp, nomatter how I configure it it will take on average 3hours off my standby time. Did it on my HTC Hero, Does it on my SGS2.
I try reporting it to the devs they just ignore me.
I uninstall it and my battery life comes back up to normal. I admit though that others are definitely worse, but I am just saying Ive personally had drain issues with Whatsapp over two different handsets over the space of 9months/a year.
Defo not whatsapp i have it and its never held a killer wake lock. But u defo have a badass wake lock. One of the worse ive seen. What social apps do u have? And whats ur syncing like?

Moving to Q&A
As I'm looking at the usage. Maps seems to be the biggest component but I haven't used Maps at all. And location services icon is basically on the whole time. And I tried disabling everything and that icon is still there. I wonder if thats the issue.
I left the phone on my desk (no wifi) at 50% and when I work up, it drained to 4%. That's a big no no.
Wondering if anyone is having the same issue.
Thanks,
Tom
That's very odd. I'm not having that issue at all. Something is truly chewing your battery up.

try opening maps so it can get a lock on, then exiting. maps might be running in the background.
Maybe play with it for a couple more days, and if you keep having issues just exchange it for a new one.
That kind of battery drain doesn't seem right to me. I I'm a fairly heavy user and I'm able to get almost a whole day out of the battery

I definitely don't have this issue but it sounds very reminiscent of the maps/latitude issue that plagued jellybean roms for a while and prevented deep sleep. I would try to get a maps gps lock and disable location sharing in latitude settings and see. If it persists have it swapped.

Most definitely a wake-lock issue. Something is staying awake. Go into gsam, and on the launch screen look at the app usage list on the bottom. Something will have a very large % of usage. Then you will have to deal with that app.
I assume your post was in reference to the OP - however, looking at the app usage list doesn't always tell what app is causing problems.
Look at the screen shot I posted right above your post. The top 3 %'s aren't apps, and it really gives no reference as to what could be causing my kernel to be so high ont he list.

If you choose app usage, then press the little arrow at the top right of the screen, it will list options. Choose the one that says "view time held awake". This should show you the offending app.

Oh, true. Thanks for that! I've never known about that feature. I'll have to check it tomorrow during the day and see what it says. I have a feeling it's just going to say "Android System" or "System *wakelock*" though.

This kind of apps is a waste of time. I tried a lot when I first bought my S2 SHV-E120 HD and finally this kind of apps end-up taking more battery to save battery, it doesn't work.
Plus these apps that kills apps to save battery also end-up by your phone working all the time to restart those killed apps. Not good.
Use Gsam battery monitor to find which app takes your juice and take Titanium backup to FREEZE these apps and the one you never use.
Yes, Don't waste money on such apps. Better get tasker and use it to configure phone as per your requirement.

Juicedefender doesn't actually kill apps to save power. It doesn't actually touch your running apps at all
It disables networking (it enables networking periodically so email and whatnot can update) when screen off and (in paid versions) underclocks idle clock speed

Jd is great. It really saves bateu by turning all your radios off and underclocking. The radio off saves the higher amount of battery. The bad thing about that is not receiving whatsapp messages high away. You can set the sync time every couple of minutes, but the use of battery will increase too.
Also would make a little harder to use a tracing software in case you get robbed. Cerberus can work with it, but as far as I know he is the only one.
Since I bought my second battery, I don't worry about power anymore so I have up on Cerberus.

You don't need an app to turn off your radios. And why are you buying a quad core phone if it's to underclock it. It's like putting 6 inches wheels on a Ferrari to save gaz.
Here is an idea, turn your Power Saving mode ON, turn OFF GPS-Bluetooth- synch and set your phone on Airplane mode and never turn on the screen. The battery will last 3 days and you will have a nice 500$ paper weight.

Totally agree.
You can set everything through settings. I've tried so many and all give problems.
One common problem is they turn off things that you might want to use and then you wonder why this or this feature doesn't work.
I can't help it. Hijack coming up.
Well, I can't vouch for JD, though I do understand, it can have a positive impact if you absolutely know what your doing. It takes experimenting to get it just right.
But anyway,
I revisited a similar but far simpler app named Green Power.
I use it to disable wifi/data 20 secs after the screen turns off since I do not care for PUSH messages etc.
GP turns wifi/data back on after I unlock my screen (or when I am on power)...and on the S3, there is virtually no waiting or interruption before you can start surfing etc. This...I do to gain max battery saving in standby. (without switching to AP mode)
I spent several years experimenting with battery savings including using Tasker. I can tell you quickly here that standby drain went from 1% - 1.5% per hour or more...down to .5% or less. Main juice sucking culprits are wifi/data tx/rx, and apps like Maps/Location/Push/sync all that stuff. It works and I can repeatedly prove it...and like I said, Green Power is simpler. Juice Defender can do the same or better but used incorrectly, can do more harm than good.
I uninstall this app because i have not seen any difference ...
I have battery killers like Facebook installed, maps running (Location updates off of course) and whatsapp sending push messages all day. Can easily use the screen for over 4 hours over a 24 hour period which normally includes playing Dead Trigger (Which kills the battery like crazy) or Punch Hero. No need to constantly turn off my data. I leave GPS on too, the only app that is allowed to use the GPS is Maps & Bus Checker. Simply leaving it turned on whilst no app is searching for your location is as good as turning it off. Of course if you have a rogue app constantly polling for your position, having GPS turned on will drain the battery
What options of gps settings needs to be enabled?
I have this:
Enviado desde mi GT-I9300 usando Tapatalk 2
I agree with themadproducer, jd if set up right is a good app, the same with green power
Juice Defender is useless since Android 2.2.1 and higher. On Android 2.1 it was GODLY. I recommend you to not use this app anymore, better do it yourself and it will save you alot of memory and battery.

U should reset ur phone. G2 battery is very awesome. I turn on everything 3g, WiFi, sync, Facebook, viber, ... And I use my phone to read news whenever I have time, so my screen time on of my phone one day is usually 4 hours. Everyday I get home with approx 40% of battery. But one thing I recommend u is u should buy the app lux auto brightness replace for stock auto brightness. I was really surprise after I installed that app, it save for my about one hour screen time.

Take a look at the wakelocks, alarms and see what is keeping your phone awake.
Also , posting a screenshot of your battery life graph would be beneficial.

Edit: Agree with quachhanthanh about Lux Auto Brightness. Totally worth the money , even though the free app does its job admirably.
Ah good idea with lux auto brightness.
I will test this too.

It really helps to know the stats to start. A rogue app or service can cause a lot of issues. I had a contact sync issue that drained my battery quickly. Found and fixed.
I use greenify(really good for battery life) and also under google settings, I mean the app you have called google settings, uncheck all those things you dont need including under Android Device Manager -> Remotely locate this device. I disabled alot of things in there. If you need to leave wifi on you can also change your wifi scan intervals to like 360 in the build.prop. Thats just for starters.
Great battery here!
As has been said, a battery graph will help out a great deal. If you have a rogue app, it will show a higher percentage of usage than other similar apps. If services really high, you might want to take a look at exactly which services are running. Be sure to always disable any you don't actually use. Also make sure your screen is set to turn off quickly, or use that nifty knock off feature. One last thing, if you are in a spotty coverage area, your radio will broadcast at maximum power trying to find a tower. That searching will kill any battery.

I'm getting horrible battery life.. About 2.5 hours screen time with 45% left. Screen has only used 20% of the battery.. its mostly being used up by Android System (33%) and Android OS(13%). I've got wakelock detector installed and its saying most of the time my phone is in deep sleep... God know's what's the issue.
P.S: I'm even using DS Battery Saver to force deep sleep... I really don't know why the OS and system are using so much battery!
P.S: Using better battery stats, it seems I'm having the activity manager causing wakelocks and the alarm rtc and powermanager service causing wakelocks... anyone has any idea how to stop this?
Almost 40hr with 4.35hr of screen time and still 38% left.
What can i say. I am happy
in two days and im with 20% , is that good or bad?
with normal use

Depends on what you do with the phone. I can drop 20% in like 3hrs easily using spotify alone.
At the moment im at 37h 12m with 3h 8m screen on. Im at 40%.
Here are my stats. I wonder why there's such a variance between different phones. Do LG source batteries from many different manufacturers? Maybe they don't do enough QA on the batteries? Battery life for me isn't terrible compared to other Android phones I've used (many won't even last a day), but I definitely need to charge it every night.

Useless, can't see your app usage.
I recommend posting in the comparative battery analysis thread.
Make sure you post all screen shots otherwise OP will be on your case.

Hi Guys!
Following Question. I got myself a new Galaxy Tab S3 and realized somehow, that i got a massiv Battery Drain. For examlple today after i finished charging i didnt used it for couple of hours and leaved it idle and locked. After 2 or maybe 3 hours i saw that the battery lost abt 6 or 7 percent. Does anyone saw some similar problem? I already tried wiping the cache.
What should i do in that case?

Does the Wifi usually drains that much??
For some reason it does on this tablet. Tried freezing apps, greenify, and naptime with same issue

I'm having serious issues with battery life, tried with all those apps, rooted. The battery life on this thing is a disaster

Battery life is great as far as SOT, stupid tablet just doesn't enter sleep unless you turn off wifi. Hopefully a future update will come out that fixes this or we'll see some custom roms that have this issue resolved.

But in actual use, I could be annotating a PDF file with the pen and it seems to drop really fast while the screen is on!

Odd. I use my tablet for media consumption and I have to charge my tablet every week & a half. I usually have it streaming videos around 75 minutes 5 to 6 days a week, so the really quick rough math is around 8 or so hours of SOT.

For me too when i use my tablet for writing, but i guess it's the digitizer
I experience large battery drain by wifi in sleep as well. After two/three days of idle tablet won't even power up until I plug it into the charger. Turning wifi off before putting tablet to sleep helps, but's really annoying. One would expect Samsung would fix this ASAP.
I take my earlier comment back, aqdc still has the wifi drain bug, very annoying. Also, the new ipad pro makes this look like a joke. We need an 8895 in this tab not useless qualcomm chips.
Latest AQF3 still has the bug, I guess it's time to give up on this tablet and just use my S8+ for everything. Samsung support thread in case in anyone wants to vent:

Tried to find the root cause using wakelock detector and greenify, didn't yield much. The problem is likely at the system firmware/wifi driver level. I suggest all folks start returning their S3s , teach Samsung a lesson.
AQF5 build came out today for Korea, trying that now. The way they are increasing the build numbers, hopefully they are actually fixing something. Interestingly this had a modem file too though the SM-T820 is wifi only.

No dice still with AQF5 KOO firmware today, I officially give up. Likely a hw issue , only reason they have not addressed it across 6 firmware updates. Too bad since the tablet is very decent otherwise. Unlikely this will ever get fixed at this point since this is not a Note 7 type headline grabber. Time to find an used S2 to replace the one I sold or wait on something else.My S3 is going back tomorrow.
SOLUTION for SAMSUNG S3 TAB
go to SETTINGS - CONNECTIONS - in the right top corner click on ADVANCED. click on to "KEEP WIFI ON DURING SLEEP" and select NEVER.
I was pulling my hair out as my tablet was running out of battery unless I manually switched off wifi. Hope this helps.

Oled display`s use a huge amount of power when showing white/light screens, oled is best for video(supposedly use less power than lcd)
Buy an lcd display tablet if you do a lot of writing/drawing.

+Turn on airplane mode
I noticed that Cell standby take from battery even if you don't have sim card
++ Go to developer options and turn on do not keep activities
+++ Advanced WLAN Settings >> Keep WLAN on during sleep >> never
