I have my phone running 99.6% of the time in spare parts and it shows android system as the culprit holding a partial wakelock.
so my question is, how do i fix this? i've tried a factory reset three times, am updated to 1.21 ota and have slowly started to reintegrate apps but it always starts again and always after a different app.
i'm getting pretty frustrated anyone got any ideas?
UPDATE In my case it was network time abusing wireless location service that was causing the problem and hence the reason a factory reset didnt solve it, i switched off network time and voila!
just to clarify, no live wallpapers, and phone is in airplane mode to avoid any data usage drainig the battery.
i have got beautiful widgets homescreen small clock and pure cal widget installed at the moment but even when i uninstall them it doesnt fix it, also im running launcher pro 0.4.2 but also had the problem when i reverted to sense.
and i have read every other thread here about battery life that i could find but no-one seems to have this problemo
anyone with any advice on why my phone wont sleep?
A long shot, but go in to Mobile Settings and untick Enable always-on mobile data.

ok cool, giving that i try now but i had been leaving it in airplane mode to try and take the vagaries of data out of the equation.
this started about a week ago and i really noticed it when i was in a 6 hour long meeting and my battery basically draines 60% even though the phone was in airplane mode
ok tried that but with my phone just factory reset, airplane mode and no apps installed other than spare parts it's showing running 94.1 % of the time and all of it is android system.
that cant be right
i have restored data, maybe i shouldnt restore data either but that just seems plain crazy
Re: Android system - partial wake lock
What exact foreground and background processes/services do you have running when this is happening, any idea?
Apps like System Panel can show you them and some useful other details. That is certainly too high.

ok right now there is
com.android.syncml.service
sense
market
messages
people
rss reader
syncml provider
sys panel
touch input
updater
and then a load of inactive cached applications
do you see anything unusual there?
ok so i downloaded system app and killed all apps except excluded and sytem apps and my running usage has gone down, now thats no suprise in and of itself but now i need to see if it stays down.
i've just checked again and the percentage is still going down, so it's either an inactive app which i didnt list ( is that even possible if its inactive) or one of the items i listed above.
has anyone got any thoughts.
What do the logs say upon going to standby? (Use aLogcat to watch/save system log).
I had same problem I tried the turning off network always on to off, didn't change anything. the thing that worked for me was turning off my flickr account!? For some reason it kept my calendar awake so keeping system from sleeping, don't ask me why as I can't figure it out, though since doing this I'm now getting up to 2 days of average use from the battery. Also I've done the usual of reducing the different accounts sync timings etc.
Have you typed *#*#4636#*#* into the phone key pad to look at what is happening? This can give valuable info on what's draining the battery.

I have the same problem as OP since the latest update. The *#*#4636#*#* code is not helping in this case. The partial wake lock is displayed as Android System - which doesn't tell me anything.
I read something about the Calendar issues but I am unable to stop the calendar in running processes.
How did you solve your problem?

Ok i seem to have had some luck since last night though i'm not sure of the exact reason.
i did as th3 said and downloaded system monitor and then killed all background active and inactive tasks and that seems to have solved the problem. I have no idea why that would be the case though and i am watching it carefully to see if it stays fixed.
i dont have a flickr account setup

Djet, I installed alogcat and have found all references to wakelock, rather than post the entire log
D/PowerManagerService( 77): wakelock: PARTIAL_WAKE_LOCK 'NetworkLocation Check Location' activated (minState=0)
D/PowerManagerService( 77): wakelock: PARTIAL_WAKE_LOCK 'NetworkLocation Check Location' activated (minState=0)

there are also some entries in red like this one
E/vold ( 53): Unable to lookup media '/devices/platform/msm_sdcc.1/mmc_host/mmc0/mmc0:0001'
and a load of errors to do with global search etc but this is all pretty much gobbledegook to me, what am i looking for?
thanks
ok so based on that log i have switched of the use wireless networks to find my location (not gps i hardly ever use that anyway) and now the running % is dropping fast.
i will keep you posted as to whether it keeps coming down or not.
it is going to be an enormous bummer if i cant use wireless location, thats one of a smartphones greatest powers, why would this suddenly start happening now ( started about a week before the ota update) and continues even when i factory reset.

I suppose it's not the feature itself guilty but the applications using it. I had the same issue with battery running out because of Location service wake locks. It turned out one of the Locale app plugins was abusing this service. Having it uninstalled battery run became normal.

Yes i know what you mean, how did you go about diagnosing that? also i have done several factory resets and it still happens
Re: Android system - partial wake lock
There are a many app settings that drain battery and the stock setup is nothing I am fond of. Location/locale was one of them for me, calendar, network time and widget/app syncs being the others. A non-stock app causing such problems was NetCounter.
Calendar was fixed by killing it and restarting it. It's a known bug for many.
If many widgets are running sync very often, then you can imagine battery draining fast.

Good find. I had the thing off anyway, but it is good to know.
Battery Save Like RandomKing
I find myself regularly repeating many of these suggestions on many threads to many different people on how to extend your battery life. When not in use, my phone loses at most only 1-2% battery per hour! So I'm making one thread in the Epic forums dedicated to maximizing battery life while trying to explain why these steps will work. Some battery improvements come at the cost of performance or lack of certain services. This must be distinctly understood, or nothing wonderful can come of these steps.
Step 1: Brightness & Battery
Let's face it. Our Android phone screens are huge. This feature is the largest, and completely unavoidable battery-drain. The only way to limit it is to not use the screen... ergo... not use your phone. But that clearly makes no sense, so how to limit that drain? Well, a good step is to turn down your screen's brightness to the lowest you can read clearly, don't hurt your eyes! For night-time use, there's an app that can turn the brightness down even lower called Screen Filter(Thanks to iModMM for the find!). Also, choose a nice dark background, something in the black color range. For all phones, the darker the color, the less brightness used, less power consumed! But for our Epic's Super Amoled screen, specifically, a black pixel is technically an "off" pixel. That's right, every black pixel on your screen is a part of your screen not being powered, since the Super Amoled does not need backlighting. Blackle is also a good alternative to the standard Google site for a black themed search engine, though it doesn't seem to be mobile optimized. Also, lock your screen with that nice little button on the top right side of your phone. Don't wait for it to lock itself! As far as the battery itself goes, charging to 100% can be tricky. The moment that led turns blue, your phone has generally reached 100%, but it will generally trickle charge between 97 and 100 after that. A good way to charge to 100 percent is to use an external charger, which generally come with 1 or 2 spare batteries for about $20. This way, the moment your battery dies, shut down, and pop a fresh one in.
Step 2: Using a Custom Rom
At this point, there are many Epic 4G custom roms out, and if you're in this forum, you've likely rooted or are trying to root. Well I will not go into rooting directions here. Take a look at one and see how it fare's out-of-the-box for you. If you choose to use my customized rom, you will find a task manager with a preset ignore list, ready to use as a one-tap app-closing widget; as well as the service-freezing patch mentioned below in Step 8 ready for execution through a terminal, and my entire setup(among many other mods, apps, and tweaks tested for the greatest battery performance). These are just roms I've used myself to great results. Many others exist. Updated 7/6:
RandomKing's Customized Rom
2.2.1 EC05 v.1 Plus [Journaled w/Genocide 1.0] [Screenshots]
SyndicateFrozen Rom
2.2.1 EC05 v.1.2
Bonsai Rom
2.2.1 EC05 v.4.1.1 Not Supported on XDA. Sorry.
Midnight Rom
2.2.1 EC05 v.5.3
Step 3: Disable Unnecessary Services
First and foremost, disable all location services, wifi and gps based. This will affect certain apps like weather apps, you'll simply have to deal with static locations. Next, disable data sync. Contacts will not synchronize with Gmail while this is off. You will have to enable it sporadically. The Gmail app also will not function while this is off, I recommend using the email app and simply adjusting the refresh interval. You can always manually check your own email . Likewise, you may put your phone into airplane mode altogether if you don't plan to use it for an extended period of time, such as school, work, swim meet, movies, or on an airplane.
Step 4: Task Killers and JuiceDefender
First, let's get JuiceDefender out of the way. It's a neat app, and in certain ways, effective. However, it's own effectiveness comes with certain contradictions. It disables nearly all signals, which will include, for example, Google Voice. In my experience, this app hindered certain other services, and if anything may have drawn further on my battery. My recommendation is to stay away from it. Now onto Task Killers, they are good, and they are evil. Let me explain. Many of us may find issues closing all the apps we open, and sometimes forget we left something open. A task killer can easily ensure that you've closed all of your programs. Now onto the bad. Task killers can try to kill certain system services. This is generally BAD. Certain services shouldn't be killed, and others can't be killed, and the ongoing battle only further drains your battery while trying to kill services that AREN'T actually bad. So on that note, the worst part of task killers is AUTO-KILL. Disable it! Kill it! Kill it with FIRE! I use Advanced or Adao Task Killer, with no auto-kill. It is one of the only widgets I use, and I simply tap it before I lock my phone each time.
Step 5: Widgets
If you don't need them, don't use them. Almost all widgets make continuous unnecessary calls to the Android system, and this can be a huge battery draw. Even simple widgets. Through all my testing, there's only 2 widgets I have approved thus far: Advanced Task Killer, Power Control. Other disapproved widgets: Pandora, Winamp, Weather(ALL OF THEM), etc.
Step 6: SetCpu, Voltage Control, and Over/Underclocking
As with much of this thread, this is opinionated and empirical theories. Through my testing, Overclocking is unnecessary, and guaranteed to draw on the battery. Most of these roms come from fantastic devs and are, by default, blazingly fast. Overclocking is completely redundant in my opinion, and I'm generally all about speed. Underclocking/undervolting may preserve more battery, but my opinion on the matter is similar to my feeling on widgets. If you don't need it, don't do it. If you feel the need to use these apps, a generally accepted setting for battery preservation is to undervolt to 800 max. and 100 min. (if your phone can handle it, some may experience wake-locks, raise min. to 200) on conservative governor, adjusting your profiles for when the phone is locked, unlocked and etc.
Step 7: Unnecessary Apps
Free apps are great, aren't they? But how many have you gathered, just because they're free? Now how many of those don't you use, but regularly draw on your phone regardless. There's an easy way to roughly check. Open your settings. Now go to Applications. Manage Applications. Take a look at which are running that you have not opened. Using a task killer prior, and waiting a couple minutes to see what re-opens may be a good way to check which apps are continuously running in the background and evaluate if they can be removed.
Facebook --- Notorious for running in the background. Disabling notifications may help.
Latitude --- Largest offender of location service usage. Neat app. Huge battery hog.
QIK/Fring --- Any video chatter really. If you don't use them, remove or disable them.
Browser --- Large ram usage. Try Dolphin Mini or Miren.
Step 8: Freeze Services
Using Titanium Backup Pro, MyBackup Pro, or Bloat Freezer (yes, non-free apps) freeze any of the following services:
sns --- (Will disable sns)
snsaccount --- (Will disable Facebook contact integration)
drm --- (May affect media programs like mediahub)
drmcontent --- (May affect media programs like mediahub)
systemupdater --- (Best disabled if on custom rom)
Enter the following commands into the Android Terminal to manually freeze the above services:
Code:
su
pm disable com.sec.android.providers.drm
pm disable com.sec.android.app.sns
pm disable com.samsung
Simply enter the previous commands into the Android Terminal while substituting "enable" for "disable" to manually defrost these.
If you would like a shortcut for this method, check out the patch in This Thread Also Included In RandomKing's Rom..
Step 9: Journaling
Journaling... some love it, some hate it. The fact remains, journaling enables extra write cycles. While this will prevent data loss, it also means more cpu usage. It follows that battery should last longer with journaling disabled. You can use chris41g's mod HERE to turn Journaling on/off at will.
Step 10: Turn it Off and Spend Time With Loved Ones
That's right. You're obsessing with your phone. Leave it be. Do something meaningful and memorable. Have fun with life! This is just a phone.
More coming as it comes to me! Including mods, apps, etc. aimed at improving battery life. Feel free to leave your own suggestions or questions! If this guide and it's features have helped you in anyway, leave THANKS so I know whether or not to keep up on it!
Y is this in q&a?

has anyone noticed an effect on the phone's ability to sleep when you manually reorder the apps alphabetically in the app drawer? I kept having problems and factory reset 2x. Now I did find 3 troublesome apps that although not apparently running in the background, kept my phone from sleeping simply by being installed. I also stopped ordering my apps, deleted the troublesome apps and now it seems my phone is working correctly. I wonder if that (editing the default order) could also prevent the phone from sleeping? Any thoughts?

I'm non rooted stock EC05. I used to use EDIT in the app drawer to rearrange my apps in alphabetical order (they don't arrange themselves automatically this way after rebooting). I had noticed in spare parts that my phone was never sleeping and killing my battery. I did a factory reset and it worked as advertised. I slowly added apps back until I found two that seem to prevent my phone from sleeping so I uninstalled them. Phone worked fine for a while but then started acting up again. I repeated the procedure, leaving only the apps my wife's phone had (hers always sleeps like a baby), but then my phone started up again. Tried another reset but this time decided to leave the apps in the order they put themselves and so far so good...wondering if that was doing something or if it is an app update that goes bonkers?

Hmm. If you can't narrow it down to a certain app, I'm not totally sure what it could be. Have you tried clearing the data/cache of Twlauncher? You could try a launcher like LauncherPro, you don't have to be rooted to use a different one.
No but if the problem comes back up I will try some of those...these are the 3 apps that when loaded caused problems: NIV Bible, Document Scanner, [I now have relacement apps for each of these now] and most recently Espn Score Center, but my wife had all of thse but the doc scanner and had no problems
i would check in spare parts to see which apps may be holding a partial wake lock. for me the facebook app was not letting my phone sleep until i disable all of its notifications.

Likewise. This is why I removed facebook altogether. The new mobile site has proven to be pretty useful now.

Yeah I found the same thing...but I would log out of Facebook too. Also the problem reappeared after a factory reset and I had not gone into Facebook. Are you saying that even if you don't log in, it can stop your phone from sleeping? My phone started doing it again a few days ago for no apparent reason, and I was able to stop that behavior by: finding and moving 2 apps from the phone to SD card (I thought I had gotten all of them), clearing any cache from different apps, and rebooting.

That wouldn't tell me anything when I had the problem. The only thing was Android System....and....the phone wouldn't sleep even if in airplane mode! Which meant it had to be a process or app doing it all the time. I had never thought to clear cache, but I wonder why doing that works? Also there's a menu option in Spare Parts about Button Behavior which leads you to believe you can make the phone sleep but the menu says "only available in Ver 1.5". I've checked the market and can't find a ver 1.5 Spare Parts...

I believe it means android 1.5, because that says "End Button Behavior", and no new phones have Call and End buttons on them. Because the "Fancy Screen Rotation" says 1.5 only also.

I think you mean "Now go to Applications. Running Services." Going to Manage Applications will show all non-system applications and not tell you what is currently running, AFAICT.

Sounds to me like a system process may be the cause rather than any particular application. For me also I had issues early on with the SNS service forcing itself to restart continually and being a battery drain. It usually takes a force stop on that service followed by clearing data in the sns app and rebooting to fix. Don't know if that will work for you, but hope it helps.

My tips you can add:
1. I always, no matter what, always have brightness on lowest setting! If you have a hard time seeing in sun, than do auto, but turn off when don't need to, I have on low 24/7. Then at night, I have this app called screen filter which lets you lower brightness then default setting(good on eyes).
2. I always have auto-sync off. If you want emails etc. configure with ur preferences. And most of the time background data. But with background data off, you don't have access to market and have to enable for use. Don't get notifications. Lately, haven't been getting WhatsApp messages. This is optional.
3. In wifi settings, network notification turned off. Haptic feedback and all vibration disabled. Sounds on key clicks or anything disabled. Auto rotate screen off. No window animations. Screen timeout, 15 seconds. Keyboard timeout, 3 seconds. In location, use wireless networks and gps satellites unchecked.
4. No live wallpaper! No bright colors! I use a black background for wallpaper!! Try to go a little dark, not bright, stay away from white! Id recommened, the full black wallpaper. Also on ur homescreen, avoid widgets! Especially ones that use live web feed like, facebook, scorecenter. These are battery suckers!
5. I delete all apps I do not use! Stock and user. Download titanium backup to fix this issue. I freeze, system updates, swype, drm content, drm content launcher, sns, snsaccount. I uninstall the stock browser, use dolphin!! I also uninstall, all sprint bloatware, my files, gmail, email, talk, news and weather. Uninstall all stock and user apps you don't use! Check spare parts to see what runs in the background that you don't use. Another thing to add, I uninstall swype and android keyboard and use better keyboard gingebread edition 8.
6. Disable refresh interval in facebook, do it manually when you are going to use it!
7. Use setcpu. Undervolt to 800max and 100min on conservative governor. Set profiles, when phone is locked and etc.
8. Now lets talk about juicedefender and task killers. Juice defender will work and is a good app! BUT: if ur a person like me, I text a lot in whatsapp and when u lock screen it disables data, so u wont get texts. Download it, take a look at it, try it out. I recommend using agressive mode. Now lets talk about task killers. Personally, I think they dont work at all, and actually waste battery then save it. I just would say don't use one, and use samsungs stock task killer(actually works!)
9. Use a custom rom and kernel. Always be up to date on updates. I usually use, SRF and midNight. All about preference.
10. Extended battery FTW!!! Buy a seidio extened battery! May cost some money, but will greatly increase battery!!! Or get a cheap asian knockoff on ebay.
11. Disable data and put phone into airplane mode when it wont be in use for a period of time. Like at school or work. I usually keep data off during school. You will see a difference with data on and off.
12. Always keep wifi, bluetooth, gps, 4g off when not in use. They will drain battery crazy!!! Wifi will search for networks constantly, same basic thing with gps and bluetooth.
13. Also do full charges!! At night shut off phone and let it charge for a good 8 hours. Then in morning, turn on still plugged in. The charging indicator will be red, leave it alone till its blue. Go get dressed and eat some breakfast lol. Then when you come back it should be blue. And when on boot, let it finish media scanning, don't interrupt it!!
I can guarentee if you follow my tips, you will see a significant increase in battery life!
These are my tips!! I will add more if I can remember some more!
Typed this all on my Epic!!
Hello,
Title says it all...
I would notice overnight that my battery would be completely horizontal (no drop) and thought it was the combination of SETCPU and JuiceDefender (night profile + screen off drop mhz).
But, after unisntalling them, I noticed the same "flat line" at night and also achieved over 30 hours of battery life.
My question is... do these apps really make a difference on our phones?
Or, are the phones advanced enough to handle everything just fine?
your thoughts are appreciated.
I agree... I got about 27 hours of life out of my battery without set cpu or JD (i've never liked JD anyway because its like putting my kid on riddlin)

Which version of JD are you using? If you have the Plus or Ultimate version, you can probably still gain some benefit, but you need to learn how to custom configure the settings so that you use the ones that are still relevant. For example:
Where Not Helpful: JD will turn off your GPS if an application isn't using it, but most of today's phones will do that anyway.
Where Helpful:: In advanced settings, you can provide a 'night schedule', wherein during this time, JD will disable mobile data, and thus polling, so your phone will not go out and check for mail, FB messages, Tweets, etc. Otherwise, mobile data is off unless you 'wake' the screen for some reason. Or another feature that 'trains' your wi-fi to only activate when you are at home or a 'recognized' wi-fi spot. These are a couple examples, there are others.
Where it MAY be Helpful: JD can disable mobile data for a custom # of minutes (10/15/30/60) and prevent background sync during those periods. It will awake, allow the sync, then turn mobile data off. Now some apps may only sync in these intervals anyway, but unless they're all syncing at the same time, you could have lots of 'up' time. Some of this may not 'wake' your phone from Deep Sleep, but depending on how sloppy the code is, it might.
Hope this helps.

Hello,
Title says it all...
I would notice overnight that my battery would be completely horizontal (no drop) and thought it was the combination of SETCPU and JuiceDefender (night profile + screen off drop mhz).
But, after unisntalling them, I noticed the same "flat line" at night and also achieved over 30 hours of battery life.
My question is... do these apps really make a difference on our phones?
Or, are the phones advanced enough to handle everything just fine?
your thoughts are appreciated.

I think really depends on the ROM you are running. ViperROM has a script that changes the CPU speed and governer on the fly. So no need for SetCPU there. I'd say Juice Defender can still come in handy with turning data off when you aren't using it.
My 2 cents. Your results may vary.

Which version of JD are you using? If you have the Plus or Ultimate version, you can probably still gain some benefit, but you need to learn how to custom configure the settings so that you use the ones that are still relevant. For example:
Where Not Helpful: JD will turn off your GPS if an application isn't using it, but most of today's phones will do that anyway.

I use ultimate. I did run a night schedule, but that kind of points back to my original observation... I'd have night setup from 11pm - 7am and see a horizontal line for battery during this time (wow JD is really working)... BUT, with it uninstalled, during the same period of time 11pm - 7am my battery was also horizontal line... So did it really do anything? I'm on wifi at my house so when I'm sleeping the phone is wifi and not constantly pinging the mobile network (does that make a diff. being on wifi)?
I also did like the wifi only when home setting.
With ViperRom, I probably don't need set CPU anymore... Maybe i'll throw JD back on.
One question.. were you running the beta JD? I noticed the beta would always throw errors in the log stating i needed to uninstall, reboot, reinstall (I never did) anyone else have that happen?
These numbers sound like you have the radio off and don't turn your display on. Pretty amazing numbers otherwise. Would love to know the rom + kernal you're using
edit: I see the post above you mention viperrom. Typically if you have data turned off and display off any device will last days. My OG evo lasts for around 48 hours just sitting there. Still really impressive if you're using your phone within that 30 hours

I've never tried the beta; I started with standard, upgraded to Premium, then eventually upgraded to Ultimate (I use the 'Customize' setting, but rarely the 'Advanced' config).
I hear ya on the night-time wi-fi thing. But with this particular phone (and before I rooted and changed ROM/Kernel), on some nights I would be connected to wi-fi and get ZERO CPU sleep time, other nights it would sleep - I have no idea why. It is conceivable that if the only polling your doing is e.g., Gmail, that either it doesn't happen at night, or it happens in such a way as to not knock the phone out of sleep (it IS Google's OS after all).
On a related note, I'm using K-9 mail (my primary mail is Yahoo); it throws wake-locks all the time (set to poll every 15 minutes), but they don't seem to impact battery life or take the device out of deep sleep which is why I suggested that case above.
One other item I like about JD is the ability to permission each and every app for wireless/network access; obviously mail, calendar, phone, etc. need it, but some apps simply don't, and I've been surprised when I set it to 'notify' and some random game pops up seeking network access. Looking for an update? who knows, but I lock 'em down anyway.

I do not turn off data/radio (no airplane mode).
I'm running ViperRom 2.2 with the latest loskernal experimental.
My display was on for roughly 2 hours (again, just used it as i happened to during the course of the day) and data was on.

Interesting thing is with the latest JD build it has the bluetooth settings, so i can leave my headset paired, but the phone disconnects while not on a call and then when i get a call, it turns on... kinda cool.
In regards to the permissions... do i need to give the email applications permission for enable/screen off? (so that I'll still get the notifs?) or just enable (as in when screen on).
thanks,

Hi guys,
Though I have been reading these threads for quite some time now, I just joined so that I can post the issue that I am facing.
I am rooted and using Liquidsmooth v2.4
I am facing a battery issue. Battery life is short. I never survived more than 2 hours of screen time on my device which I know from these forums that is not normal.
The stuff I have tried but didn't help:
Wiped and factory reset on several occasions, both using the settings function and CWM
Flashed various roms (Cyanogen Mod, Carbon, Liquidsmooth, Stock rom)
Unroot to stock and root again
Changed to various more battery friendly CPU governors
Changed battery with a friend who is using the international version (which is using the same battery according to the Samsung website)
I am not in the states now and the local Samsung service centre refused to service it because they don't have the appropriate parts and also due to the difference in software. (I unrooted it and restored to stock before sending in.) They just looked at the model number and refused service; didn't do anything more.
I have attached some screenshots. There are no obvious wakelock issues and no app in particular is draining the battery. 50% power used on screen appears to be normal. The rest of the apps also look like they are behaving themselves, at least power consumption wise. I am not a very heavy user and don't run any games/apps that are huge in resource requirements. Email/facebook/browsing are my main activities.
The current settings on my phone:
Auto brightness
Wifi/bluetooth/GPS all off
Autosync is off by default but will use it sparingly if I need to.
Almost all of my apps have their notifications off and all apps are set to sync manually.
I only have one calender widget on my home screen, no others elsewhere.
CPU Governor is "ondemand", iO scheduler is "row". Min/max freqency: 384/1512 MHz
Juicedefender is enabled with "aggressive" (I know its effectiveness is controversial but on my device, disabling it eats more battery)
Any help is appreciated. "Thanks" will be awarded to all who post!
Thank you!

I see horrendous wakelocking. Install BetterBatteryStats. Charge it up for a bit, reboot the phone, then let it idle for a couple hours. Then post screenshots of everything.
It might be the worst I've ever seen. Good news is it's probably not a hardware issue.
It also looks like half the time you had a poor signal. Data transfer on a poor signal can wat at your battery too.
Always use wifi when available.

thanks folks. I've installed better battery stats and will update shots accordingly at the end of the day or end of the battery cycle(probably won't last a day)
Really appreciate the help.
Here are the shots for today.
I rethinked about the poor reception comment and wondered if any of my radios are malfunctioning or if my radios can work in the frequency bands here in Singapore. I called my local service provider to ask about the frequency bands and.it appears that my device's radios can recieve the GSM bands here although they suspect 3G may be an issue. Nothing concrete but I do hope to find out if that could be a possible reason for my battery drain.
I managed to squeeze past 2 hrs of screen time today by using as much wifi as I possibly can. This improvement in battery life probably means that data reception can really be an issue. It's not unlikely that both my home and workplace suffers from.bad reception but i do have a Q. If poor reception is an.issue, will the battery consumption by cell radio sky rocket?
For some reason the previous battery stats screenshots was only for about 5 hrs. i have refreshed and have uploaded the refreshed screenshots

This is not BetterBatteryStats. We already know your battery life blows. I want to know why, and BBS will tell me. I can't do a thing for you until you show me that. I think there is a free version on the forums, but it's cheap in the Play Store, and worth it. Get Greenify, too. You're going to need it. Greenify will prevent notifications from showing up for greenified apps. If you don't need notifications from Facebook (honestly, who does?), Greenify it. Maps, too. And disable Juice Defender for now, so I can see what is really happening.
Poor cell reception, if not on wifi, causes drain, yes. It seems to only get really bad when the phone can't hold a data connection.
Try turning off GPS. Also under Settings > Backup and Reset, turn off the Back Up My Data option.
Additionally, check the stickies in this forum. Woody has a fantastic Battery Thread that you should read if you haven't already.

Thanks everyone! I sheepishly searched better battery stats on Google play and.simply installed the first that popped up without looking closely. My bad. I've purchased the app and will post up screenshots soon. I didn't manage to grab the shots today as my batt went flat before I could. Should have kept a better eye.
Will certainly post up screen shots tomorrow.
PS: My GPS has been offed by default. Will disabling Google backup services help?

It cant hurt your battery life! Theres a number of things you can do for settings. Read woodys thread stickied here as its pretty much all there. One of the big batt drainers can be auto brightness btw.

Once you get a good cycle run with BBS, the screen shots we want to see are Since Unplugged/Process and Since Unplugged/Partial Wakelocks. Those two will help tell what is eating your battery and also what is causing all those wakelocks in your original screen shots.
If you are using Juice Defender, that will contribute to the wakelocks (but doesn't keep your device from entering Deep Sleep, so no worries there). I use it, but I have mine set up custom plus have done some basic build.prop edits regarding the RILs and wifi_supplicant_intervals.
My suspicion is that there is a rogue app that is transmitting data somewhere and that is not letting you sleep. If it is transmitting in a poor reception area then that puts ever more strain of things. You are not the first and wont be the last but Doc, Aero and I can help you figure it out.
Images for today. I've included a few more shots for the items that appear lower in the lists.
I've installed greenify but did not add any apps while collecting these data. Juicedefender is also disabled. My screen time was less than 2 hrs.
I did some of the stuff listed in Woody's informative thread. Deleting the tombstone files, lost&found files etc.
Thanks for everyone's help. Hope to solve this issue soon.
Get Greenify from the play store.
Greenify:
Maps
Facebook
Google Now
Take more pictures with BetterBatteryStats tomorrow.
Looks like Maps is misbehaving. Terrible coding is terrible.
Yup. Looks like you are broadcasting your location all over the place. Do you use Maps? If not close it and Greenify it.
Are you getting notifications from Facebook or have a "Check-in" thing going on?
Google Now>Settings> turn off what you don't use.
Settings>Location> Off.
Edit: Tombstones and Lost.dir files are just memory management and have nothing to do with battery.
Shots for today. Things are a little better but looking at my screen usage, maybe there's still a lot of room for improvement.
I've greenified just about all apps that may run in the background. Facebook, Maps, Google+, Gmail, Chrome, Google Search (I converted it into user app), dropbox, etc. Whatsapp, Viber and Wechat are spared as I needed them to be able to notify incoming messages. Juicedefender is on, with advanced settings - set to sync only once an hour. Maps have been set not to update my location although I didn't go to the extent of denying location access ( I use maps fairly often).
All these are rather aggressive steps and I do see improvement. What else can be done? Other than my messengers, all my notifications are essentially off.
Once again, thank you everyone for your time and effort.
Please stop using Juice Defender. I want to see what your battery life looks like without it now. And it's also responsible for the majority of your wakelocks. And if you could get us some ~4 hour idle BBS stats (during sleepy time), that would be fantastic.

Noted. I'll charge my phone up and take some shots in the morning. Juicedefender will be disabled and hopefully more information will be revealed. Do today's shots show any improvement?

I think you are heading in the right direction (8% deep sleep improvement). For this next test, please disable Juice Defender (don't turn it off through the app, but disable it in the app manager to make sure it can't run). Also, I'm hoping to get a test where the screen isn't on for more than a couple seconds, so I can get an accurate reading on the usage per hour.
I suspect the rest of your issues (bam_dmux_wakelock), are due to a bad cell connection for a good chunk of the time. Connecting to a wifi network will solve that. If you don't have a wifi network, you can turn on airplane mode, or set up some Tasker profiles to help with that.
Out of curiosity, how bright do you have your screen set? Obviously its a big drainer, but it seems like every time your screen is on the batt level plummets.

I've lately got into developing mobile apps and even though i've promoted this as beta, people seem to be using it, but nobody's reporting back! - same goes for all of my apps, i don't get it...
Anyway, i need real feedback and I was wondering if any folks here with a rooted android could help test this app out, it was made on Kitkat, so while yes, it works fine for me, it may not for you... I've had one feedback comment saying that his modem data was not switching off on lollipop, so i added support for that now allowing him or her to use the app as intended, but after replying via the playstore, nothing was heard of him since... almost suspicious lol

Find it on Android's Playstore... Craig's Battery Saver ROOT
https://play.google.com/store/apps/details?id=saver.battery.craigs.craigsbatterysaver :good:
How it works..... read on
How it works, if you're interested!
2 things use up battery power
1. apps that are CPU intensive, eg constantly repeating to connect (this would only happen under malware, as most apps would never do this, it would see the socket it closed/dead and stop and wait until user input, malware would constantly reconnect.. but 99/100 apps will just stop and then do nothing meaning all genuine apps should 'idle' not really using up cpu time....
2. Hardware services, bluetooth, mobile data, wifi, gps, these services are all hardware, so your cpu will switch on each of these services and each one has a significant drain on your battery, go bed at 11pm, by 9am it may have drained 30 - 40% or more... with this app, it will have drained under 1 - 3% depending on your battery (tablets for example should run for days with this app if rooted)
So this app does 2, it first remembers which hardware was on before the screen goes off, so no confusing switch wifi on when wifi's already on (as i've seen on other apps?!) reason why i wrote this because all the other apps i came across sucked really, almost but not quite etc etc..
With this tool, if you're a light user you could quite easily see 60% battery improvement! the bonus side affect of this app is also interesting, for 1, it charges quicker! if you accidentally fall asleep, it will conserve as much power as possible, obviously sms,telephone/mobile network is still running in the background so you can't completely stop a device from draining...
the other bonus side affect was, it kills dead all facebook notifications, twitter, well it would as it disables wifi, modem. 3g, bt when the screen goes off! :good:
1 more feature, if you drop your phone? then what?... take where's my droid, i sms it asking for location... it replies "GPS OFF" and "modem off" simple, send the text message to your phone with "on" without the " " around on, and the app will disable itself so it does not switch off the services and then at the same time it enables Wifi, Modem Data, Gps, Bt pretty useful huh... then on where's my droid, you'll get GPS combined with AGPS data from mobile data giving you pin point accuracy, as soon as you get the data of where it is... type in
off (to turn this feature off) or
on (to turn on all your services)
It also disables itself taking calls...
It has a smart check feature too, let's say after you switch the screen on and for some reason wifi failed to switch on ? after 3 seconds it will then check again to see if wifi is indeed on... if it's not on, it attempts to switch it on again...
Feedback is greatly appreciated so i can support a larger range of devices.... thank you for reading! (Suggestions, welcome!)
So basically what your device is and what's not working (along with build version, lollipop/kitkat etc) and i'll see if i can find a way to add it in to support your droid! - one more thing, i've been releasing updates like a crazy woman collecting cats lately and even though it does all this it's only supporting "Extreme power saving option" come tuesday i hope to have that sorted out so that every few minutes it can wake up to check for twitter/facebook messages for all of those who hate the sound of a phone being blissful quiet
if you're rooted and it does not look like that in the video [top of screen] (not the interface, but the services, i've already updated the UI)
anyway, help me to make it better for you...
One more thing, there are no push notifications, no popup adds, no huge banners, all my apps have one tiny advert to help support the countless hours of programming i'm putting into this apps, with each upgrade i aim to make them more stable and more usable, and i really need peoples help and support even if that is criticism - it's "beta" but i'm almost ready to bring it out after i add the wake up services....
Nobody has a rooted device?
Unlike other battery savers... it really does work
