I installed Spare Parts and saw that my phone was never sleeping, even though it was on standby all the time.
This was caused by the location by antenna feature.
Ever since i unchecked that feature i've had around 50-60 hours of uptime, with a few calls and a lot of texts.
hope this helps alot others
With the new firmware the problem of battery dissapears completely
There is a known issue with network location detection in android 1.6. I had the same issue with my galaxy and it was solved. Now that we have root, we can hopefully do the same.
Also, br aware that I have found spare parts to actually stop the phone from sleeping, as well as tapatalk. I suggest rebooting after using either program.

Actually that issue is fixed in the latest update so it's already fixed without needing root.
Which firmware? I know I'm still experiencing it.
RBA020 solved the battery issues for me.
Where in spare parts does it show you if your phone has been sleeping?
you don't need spare parts. Just dial *#*#4636#*#* and click battery history and then the running bar.

I hope this means that under Location, you had Wireless Networks and Assisted GPS enabled.
One question tho... how did you isolate this feature as the one that was keeping the system awake?
I just found that my phone has been running most of the time, I see Running at 100% under Battery History. Then I select Partial Wake usage and see Android System has the largest share. But what part of Android System? how does one get to know?
I know from having a Samsung galaxy and being part of the androidforums community that was going nuts until Simone found a bug report with Google saying that network location was stopping devices from sleeping. We had root so a Dev applied a patch to services.odex and voila! Phones were napping again.

Hmm... time to give this a try... so is it just Wireless Network or also AGPS that causes this problem?
I hope I can still leave GPS turned on?

Didn't know that there was an XDA App till I saw your sig. Looks like its worth a try since its free!!
Update after turning location off completely
Well first run with all location methods disabled (I can still enable GPS quickly via a widget when I need to use it)... the battery performance is up phenomenally!!
I charged fully before going to bed last night, then kept the phone unplugged... woke up and found the battery was at 97%. This has never happened to me.
Ok, one thing tho, I use Juice Defender with night time schedule, so my wifi and 3G were off during most of the night. Anyways, its been around 3 hours since I woke up, and I've been using the phone on and off to do some browsing.
The battery is now at 93%.
I do not use any other aid other than Juice Defender... no task killers, no startup editors. Will update on how the rest of the day progresses.
EDIT: my thanks to Inebriatef and adrianoftyriel for pointing this out.

I too would like to hear a bit more. Could the OP please elaborate?
I'm running the latest FW and although my battery life increased exponentially, I find that it's not going to sleep anymore! I had close to 50 hours battery life and now I repeat everything to get just under 20 hours.
I don't use task killers and crap anymore, just before I put my phone away. If I don't, I have a trillion programs running with like 40mb of RAM free. Although I understand this is Linux based, these programs are RUNNING and not idle. All my **** is draining the battery again after a clean reinstall of everything. What a bummer.

@bongd, by latest FW, do you mean the R2BA020? If yes, then you shouldn't be affected by the problem being reported here. I'm still on R1FB001, which apparently has this Android 1.6 bug related to location.
As in my case, simply by disabling location settings (even though this reports that network location is the culprit, I disabled them all), the phone is now able to suspend itself and basically consume very little battery in standby.
Personally, I dont see any issue with lot of applications running and having little RAM left because I trust the Android system to manage it efficiently. Furthermore, the RAM on these phones is not as fast as what you would see typically on desktop systems, so it actually helps having things around in memory rather than aggressively cleaning it out. Checkout this link to understand a bit more about Android task management features: http://android-developers.blogspot.com/2010/04/multitasking-android-way.html
I suggest you use Spare Parts to isolate your battery drain, there might be some app that is misbehaving and hogging systems resources. Also turning off very frequent updates/refresh intervals in some applications is the way forward.
I found through trial and error that fancy widgets keeps my phone from sleeping.sad cause I really want to use it.

Thanks, j4mm3r. I am using R2BA020. It looks like I have some diagnostic troubleshooting to do when I get home.
Sitting here at work charging my phone, it isn't loading craploads of programs anymore. And it seems to be sleeping okay. I'll play around when I have some free time.
Fixed my problem big time
Hey guys,
I just wanted to throw my two cents into the pot.
OK – so after experimenting with Task Killers, Task Managers, Spare Parts, Juice Defender, etc. I came to the conclusion that they (for the most part) did more bad than good. It was getting to the point that I was just starting to accept that “The X10 just has ****ty battery life” end of story.
I also read in a Google released post on the web, that there are a number of reasons that Task Killers, etc. are actually not required to end tasks. Android actually has a fairly intelligent and systematic approach to killing tasks that are not being used. I haven’t used any sort of proprietary battery saver, task ender, startup cleaner, etc. and I’ve been having the best phone performance since I got the headset.
The time now (Eastern Standard) is 3:30pm on Monday. The last time I charged my phone was Saturday evening at 6pm, and currently I am showing 24% battery remaining. Let those numbers do the talking!
My settings are:
Wi-Fi always off unless I am going to be actively using it (browsing)
Using Phone info, I change WCDMA Preferred to GSM Only (enables 2g instead of 3g without disabling data altogether)
GPS always off
Screen settings, brightness, etc. I believe have a much smaller effect than people tend to believe. The SINGLE BIGGEST factors for me, and noticing this huge increase in battery life are:
Settings -> About Phone -> Software Update -> UNCHECK Automatic Search (this constantly searches the market, etc. for app updates and what not)
Cycle power immediately after charging. Once my phone completes its charge, I turn off and then on again.
I hope that some people can enjoy moderately extended battery life as I have. I am SO ecstatic to be at HOUR 43 and still at 20%+
Worth mentioning also that I am on Rogers (Canada) and have not received any updates, so this extended battery life is not a result of a firmware update.
How I Fixed My Batter Life Problem
My Incredible would run dead in about 4 hrs doing nothing. I finally dug into several "task killer" programs and found that about 20 - 30 apps were invisibily running in the background constantly. As soon as I permanently killed them, my battery life went to normal. I can now get about 2 days of normal use on 1 charge. Even a day of pretty heavy use will last almost all day.
So for me, it was all the new apps I installed when I first got the phone that were running in the background. The free "task killer" program was not showing them. I finally found the app called "System Panel." It was the ONLY app that would show me all the "invisible" apps that were still running invisibly in the background and let me kill them. Once I killed them with System Panel, they stayed dead and the free "task killer" program could auto-kill them from them on.
Not sure why the free programs could not see the rogue apps, but my battery life is GREAT now.

Where is this option to uncheck this feature.

I'm running R2BA023 and I am struggling to get a full day from the phone at the moment. It normally lasts around 12 hours and then its flat.
However, I ran the Telenor R2BA020 update and I manage to get a full day with ease.
I have just done a clean install of R2BA023 Generic UK "root" edtion and going to see how I get on. What I did notice before is that the phone was not returning to a idle state.
Edit: The 4.2.2 update seems like it fixed this wakelock from taking over. That's just my personal experience so let me know if yours is different from mine after the update.
I've searched and tried to find a solution to my problem, but I can't find anything. My main kernel wakelocks are sns_async_ev_wakelock and sns_periodic_wakelock and the time they both register is massive. This has been happening for at least a week, or at pretty much the entire time I started monitoring my wakelocks. Does anyone have any idea what these might be attached to? I originally thought they were pertaining to social networking services, so I promptly deleted the Facebook app and for a day it seemed to fix it. But then the wakelocks came back and were even worse.
Have others come across this problem and does anyone know what might be causing it? They've been preventing my phone from going into deep sleep and I would really like to reduce or get rid of them.
Updated info: I have determined that the game Asphalt 7 is at least one app responsible for massive sns wakelocks. As long as the game remains as a "recent app" it will continue to wake the phone up. Angry birds is another game possibly responsible for the wakelock as well as reddit sync. Anyone else that uses these apps regularly us encouraged to report back your findings. Using the phone prompts sns wakelocks, but the amount of time the phone contributes is identical to your talk time, so your phone is triggering a fake wakelock since the device isn't supposed to be in deep sleep while you're on the phone anyways. Right now the only fix I know of for the listed apps is to manually clear them from "recent apps".
Please include the rom and kernel you're using. So far it seems like a new kernel doesn't actually fix the problem when you're on the stock rom. So anyone on CM or PA, do you have this wakelock after having a game like asphalt 7 or angry birds sit in recent apps?
Have you tried a custom kernel like Franco's ? Might be the Qualcomm fixes.

Well I'm getting this on Franco's. I think it has something to do with the phone. [ I mean talking/calling on phone]
@OP,
Do you get this only when you call someone or get a call. In bbs, try a custom ref. setting and monitor for 1 hour where you were not getting/calling anyone and see if it is going down drastically. Also is the msm_hsic wakelock present for you a lot? [The custom kernels like franco, faux and others have fix for this, taken from patch commits done by qualcomm]
What were you doing with your phone in that time, were you making calls, texting, etc?

I talk on the phone for maybe an hour every day, so I would be surprised if it was associated with the phone since the wakelock time has been increasing this whole week while my phone time is relatively constant. Although I'm just taking the phone off the charger now and won't use it for calls for the next 2 hours, so I'll report back with what kind of wakelocks I'm getting as well was the apps I've used. As for msm_hsic_host wakelock, it is present but not as prevalent as the sns wakelocks. As you can see from the first picture I'm only getting about 20 minutes for that wakelock compared to the 4 hours of the others. If I remember correctly I ended the day with almost 5 hours for both sns and then an hour and a half for msm_hsic. So sns slowed down a bit and msm_hsic ramped up, but it didn't come close to overtaking sns

I was using it pretty normally. Had around an hour of talk time (cumulative over the day), texting throughout the day, streaming pandora for a little, checking emails, playing a game for a bit, and on sites like xda, reddit (through apps), and facebook (through chrome).
So far I haven't had any sns wakelocks today (well, nothing compared to what I recently had). The hisc wakelock is dominating now which seems more "normal". I only talked on the phone for a grand total of 3 minutes today so maybe that has something to do with sns. Currently charging it so I'll start getting new stats (the ones I'm posting now were taken a few hours ago), but this time I'll try to use the phone more as well as keep everything else the same. My use today has been streaming pandora, checking emails, reddit, xda, facebook, but no games (maybe that also comes into play). I'll keep updating
I'm getting massive sns kernel wakelocks too. No phone calls.

Hmm, yesterday I started getting sns wakelocks after I was on the phone for a while, so that might be part of it. Of course there might have been another reason behind it if you get a lot of wakelocks without the phone. Forgot to get a screenshot
This is the first day since I've been monitoring that this wakelock just went berserk. I made zero calls today. Then, I went back in time to determine what I was doing when it started. At that time, I was using Reddit Sync. Before doing anything, I locked the screen, and a few minutes later checked BBS and determined that the wakelock was still active after locking the screen. Then, I closed Reddit Sync and locked the screen. After a few minutes, I unlocked the screen and checked BBS. Sure enough, the wakelock times had frozen. So, by simply closing Reddit Sync, this wakelock has stopped, at least for now. After restarting this app, locking the screen and unlocking after a few minutes, I notice that the wakelocks were not re-activated. Well, that's my story. Do any of you use this app too?

No, I never used Reddit sync. However, it could be related to a general sync problem

Ha. It's not a sync program whatsoever, not in the sense that it syncs anything to the contents of your phone. It does sync in the sense that it keeps track of your "read" articles.

I only use Reddit News. My sns wakelocks for today match the time I was on the phone, almost identically. This has been the case for today and yesterday which leads me to believe that the phone calls are NOT responsible for this runaway wakelock (as others have been saying). I didn't use my Nexus 4 very much this weekend, and the two major functions I used it for were phone calls and checking email sporadically. Others seem to report substantial wakelocks even without calls, so this has to be attributed to some app or setting that we're missing. Although I'm more inclined to think it's a problem with an app (or apps) because limited use seems to result in limited wakelocks, and if it was a system setting then it would be fairly constant. Has anyone gotten low sns wakelocks after not using their phone much in a day (like not using very many apps)? And thanks for the input so far
Async could stand for asynchronous, the CPU functions asynchronously but, I have no clue whether that wake lock is really cpu related.

I think it might be but I'm not completely sure.I found out last night that the game Asphalt 7 was responsible for a couple hours of wakelocks. However, in the system battery stats it registered as 0s for keeping the phone awake while android os registered the 2 hour jump I saw after playing the game. I played for a few minutes and jumped back to the home screen and didn't touch the game for those 2 hours. I'm not sure why, but having the game in my recent apps triggered those wakelocks, and the second I swiped it out of recent apps the wakelocks stopped. Either the app is bad or maybe the system isn't handling it correctly. I'll be trying other apps to see what the results are.

I use redditsync and also had a 7hour snsw wake lock overnight... Gonna keep an eye on it and hope it was a one off (or an update gets pushed out)

Alright, so that's two people getting wakelocks from redditsync. What happens when you clear redditsync from your recent apps? Does the wakelock continue or does it stop? This definitely sounds like the system isn't handling some of the open/recent apps correctly. No idea what links these apps together though
I am using Franco 62 with stock ROM and it turns out that Angry Birds Seasons can cause these wakelocks as well. Glad I'm not the only one with this issue.
I have never had these wakelocks previously (only the famous msm_hsic_wakelock). Yesterday after I installed a couple of apps (most are just theme-ing apps with no sync) and flashed custom kernel (Franco.r53); and ever since then these two wakelocks are continously appearing in my BBS stats, almost preventing my phone from entering deep sleep AT ALL. So I thought it was the kernel's problem; flashed back stock kernel and the problem still persists.
It's really weird as I previously NEVER had these two wakelocks.
By the way, I'm on stock ROM (rooted, unlocked)

Thanks for the update. But, it begs the question as to whether you uninstalled the new apps one by one to hone in on a possible culprit?

I'm suspecting something else, will update if it's solved.
UPDATE:
This is really weird, I have uninstalled what I installed yesterday and the problem persists, so I decided to try something else (as it was the another differences factor compared to pre-problem).
My WiFi was disconnected in middle of the night and I thought it could be causing it.
I turned my WiFi off, turn it back on and the problem is gone. This is really weird, as I have rebooted many times prior to trying this solution (and even flashed back to Stock Kernel).
Really random or just plain unlucky? I have even reinstalled the apps that I thought are causing the problem, but still fine so far. Gotta leave it overnight again to judge.
Hi,
I purchased the s4 through radio shack 4 days ago. I was having issues with the wifi staying connected for more than a minute. After doing research and reading forums I came to the conclusion it was my router. I've reset it and done firmware updates and changed security to WEP and wifi issue was resolved. However now it is constantly scanning for a wifi network even though it's already connected to one. Have called samsung and radio shack sbout this and am getting various responses such as it is normal, or no it is not normal let's try a a hard reset to see if it fixes the issue. So this forum is my last resort before completely resetting the phone. Should wifi be continuously scanning even if connected to a network or not? Thanks

Mine still scans for Wifi about every 4-5 seconds even when connected to Wifi. It seems to be normal and believe it did this on my S3 as well. Unless it is draining your battery I wouldn't worry about it. Also, it may only do it when you are in the Wifi settings and not when you exit but who knows. I get great battery life so it is something I'm not going to worry about.

have you asked if it Is normal? Im pretty sure the scanning is affecting my battery life but but not

I have not asked because my battery life doesn't seem to be affected by it. Also, I think my S3 did it also. From what I find when doing an internet search everyone else is seeing the same thing so almost positive it is made this way. When I look at the breakdown of battery usage (Settings->More->Battery) Wifi is only using 6% of my battery. Look and see what is using battery on yours. If you need more detailed information on what is using the battery than get BetterBatteryStats from Play store to help pinpoint it. There is a forum just for it where you can post and get help figuring it out if need be.
Also, as for resetting, I just did a factory reset yesterday and it still scans when in the Wifi settings.
The scan interval is probably cooked into the build.prop somewhere by Samsung. Usually apps like Blade Buddy and Rom Toolbox Pro can change it but BB is not compatible yet with the S4 and Rom Toolbox doesn't show the scan option in the build.prop list. I looked at a few of the custom TW roms and not finding any changes to that listed in any build.prop tweaks.
If I had to guess would say there is something else on your device using the battery but using BetterBatteryStats can pin point it for you.
**Edit....From what I am reading it seems there is nothing in the build.prop to edit. A line needs to be added in to change the default scan interval. I'm not 100% positive on this but seems to be the case.

OK I've looked at battery usage and and wifi is at b 4% and screen has the highest percentage eventhough I have it at a lower resolution. However when I click on wifi from the battery setting it says it has only been connected to Wifi for 4hrs. 32 minutes . I've had wifi turned on since I got home last night. Could that be the issue? I did charge the phone overnight unless it shuts off while charging but still my emails would have to sync every hour. Do you know why it would say it's only been connected for 4 hrs if I've been home much longer than tgst? Thanks for the help. And also did you reset your phone due to the wifi scanning?
THANK YOU

OK I've looked at battery usage and and wifi is at b 4% and screen has the highest percentage eventhough I have it at a lower resolution. However when I click on wifi from the battery setting it says it has only been connected to Wifi for 4hrs. 32 minutes . I've had wifi turned on since I got home last night. Could that be the issue? I did charge the phone overnight unless it shuts off while charging but still my emails would have to sync every hour.

I don't know about the reported length of time for WiFi. Mine seems to be accurately reporting when I connected to WiFi this morning at work till now. Maybe it disconnected and then reconnected for something? Do you have multiple bands in your home (2.4ghz & 5ghz) to where it could have jumped between them? Did you walk outside and out of range for a sec? Maybe for some reason it had a hiccup and got disconnected and reconnected. Not sure.
Also, I did a factory reset for a Play Store issue and not because of the WiFi.
Wifi scanning every 5 seconds on my Galaxy s4
Jellybean 4.3 has been responsible for one of the highest complaints to hit android since androids launch.
Wifi overscanning
Battery management
HDMI Completely not working
The list goes on, this is all because some idiots wanted to rush jellybean out to accommodate for the introduction of the Samsung Gear. As a result of rushing it's release many elements were not tested or even included in the update of our much loved now screwed galaxy s4 's
Someone better get there act together and roll out a TESTED release to address all of these screw ups!

When this post was made 7 months ago, the S4 was on 4.2.2 not 4.3. Way to revive an old invalid thread. Also, all the things you mentioned work great on my phone so calm down a little.

That's funny because as a senior member, your reply seemed neither helpful nor relevant to what I said about the Galaxy S4 being affected by the latest Jellybean 4.3 update (whether I posted on an outdated thread or not) The subject matter remains relevant because the Wi-fi over-scanning while connected is still very much a current issue.
Many users have complained about the numerous errors currently being recently experienced in the latest 4.3 update, many of which have now been announced on the Samsung support forums. I'm in the UK and I see you're in the US. that in itself could make a hell of allot of difference in the errors that UK users may be experiencing. I'm also on T-Mobile and that could also have implications to the version of Jellybean subversion that has been installed.
Telling me I should 'calm down' (just because you're not experiencing any issues with your phone) is not the sort of condescending remark expected from any senior member.

Well, seems you don't have the l720 so why are you paying in these forums.

I am not sure if this is a legit complaint, but sometimes I don't use my N10 for a few days and my tablet will be completely drained. I really only use my tablet for some general browsing/emails/videos. I generally turn off all automatic updates/notifications/etc as I know I may go days between use and want to conserve as much battery life as possible.
With that said I have noticed lately that my entire battery will drain after 3-5 days even if I am not using. Is that just the case? Or should I expect to not lose too much battery when inactive. I looked and 90% of the batter drain was the Android OS.
Any help would be appreciated.
Hi,
The same problem just happen to me. I've fully charged my tab yeaster day night and I found her with only 14% left. Didn't use it the last 23 hours.
WTF!

When your N10 is sleeping, you still have several things happening such as looking for updates, synchronizing RSS feeds (like your greader), WIFI connection and communication. By looking at the programs that consume the most battery during those times, you can start tackling them 1 by 1. There are a few apps that will help with battery life and to reduce drain. You can also try turning WIFI off when not in use and you don't want updates. You can also change your WIFI - Advanced settings to Keep WIFI on during sleep only when you are plugged in. You can google battery life during sleeps as there are lots of threads about this topic, which is more Android related than N10.
Just like SmokinCharger said there are other apps running, try turning off Sync initially and don't forget to turn off WiFi, this may save a little your battery, if it doesn't try uninstalling some apps that may cause this, like Facebook.

That graph looks exactly like a wakelock going on all the time and your tablet never actually sleeps. OP probably has the exact same problem.
My own personal Nexus 10 will lose about 1% battery every 20 days when sleeping.
Thanks for the help. I really do t use that many apps and don't have Facebook. I have attached some pics. Media server is using all my battery? I even turned my wifi off while sleeping.
Any other ideas?

Do you have your N10 set as a media server? If not, media server could be just looking for changes in your N10 in order to have media available - i.e. downloaded a jpg and to show up in Gallery. I believe there is a setting to not allow it to auto detect, but I don't remember where in the settings it is.
Don't have it set up as a media server. Like I said I really don't use it too much.
Enigma - you only lose 1 percent? How is yours set up?

While i may not say there is a wakelock, you can clearly see that because the app has been on and running for over 14 hours time that that process is what is causing the wakelock and draining all your battery. I forget how to fix the media scanner thing, I know I have seen it before in the forum for the Galaxy nexus, which was my old phone. What Media Scanner is is the process that scans your storage for files so that it has an index of what is on the device and so it can display the files and folders for you in Windows. most likely Media Scanner is stuck on a specific file and cant get past it so the process is staying on forever.
My personal setup is the RaSaber ROM (not available anymore) 4.2.2 and KTManta kernel (whatever the last 4.2.2 version was). I probably will never upgrade to 4.3 because this setup is perfectly smooth and the only bugfix that 4.3 brings that I would ever care about does not matter to me since I never hit the bug (playing video in specific apps using hardware rendering). I mainly use my tablet for games and book reading on trips, so it goes long periods without use these days. I never charge it in between because I know it will still have basically the same exact battery level as I left it whenever the next time I pick up the tablet is. I posted some screenshots before in some other thread a while back because no one believed me on the battery life. I went something like 70 or so days of idle and was at 97 or 98% still, then went on to use it for gaming and got like 7 hours of screen on time still before I needed to charge the thing.

Your tablet is searching for more media, maybe you can check the settings and see if there's anything set up to be syncing. Also you can try installing another ROM to check.

I had a similar problem, after upgrading to Android 4.3 a couple months back. The battery seemed to run down much quicker when the screen was turned off. However, the problem seems to have gone away now. I'm not sure if there was some media scan or whatever running in 4.3 that finally finished or if it was a webpage I had loaded in my browser that kept refreshing itself. See if you can reproduce the problem with all browsers, email, video players turned off. Check the app switcher to make sure nothing is loaded. If so, the problem might be in the OS itself. Maybe it will go away with time, as it did for me. :victory:
Hi,
You can try leaving it off, the battery will stand by then . And as Nexus 10 boots really fast you won't see any problems (mine has 2GB free and booted in 20-25sec).
Hope this suggestion helps ,

I found this in relation to this topic on a different site:
"All you need to reset is that media scanner: Settings > Apps > All > Media Storage: Force stop & Clear data. Then, reboot."
Most people seem to think this works. In a follow up, someone posted this:
"I had the same problem and none of these fixes worked. It turns it that my Spotify was the problem. It had crashed and could not find the media files i had downloaded. I uninstalled Spotify and that solved the problem"
Good luck.
Hi - newbie here hoping to get to the bottom of my battery drain problem.
Somewhat unusually I think, I am seeing problems only when I have wi-fi switched on. It took me a while to realise as I have wi-fi at work and home and I wouldn't normally have turned wi-fi off as I always understood that 3G uses more power.
I tried installing BetterBatteryStats but I am not rooted so it is only giving limited information. What it does tell me is that I am draining the battery at a rate of 9% or so an hour on wi-fi and about 1.4% on 3G. This is with very light or no actual use of the phone. The top two wakelocks by a big margin are msm_hsic_host and PowerManagementService.WakeLocks.
I have virtually nothing running according to my running processes list - mainly the Google ones like Google Play Services, Google Keyboard.
I couldn't put my finger on exactly when this started but it was towards the end of 2013. I did have the really bad drain with Google Play for a few days until the next Android update came. What I'm seeing now is not as bad as that was. I couldn't say whether I had a period after that update when things for a while were better than they are now but my feeling is that things have never been great since the 4.4 updates.
Does anyone have any suggestions please? Am I going to have to root to get better info to debug this problem?
OK, I'm too having this problem and couldn't find any concrete solution for this.
Without full use of batterystats application, the information that you provide don't help much.
Could be many things.
