Insane bad battery life - high usage from "Android system"

I'm getting quite annoyed with my S3 and its piss poor battery life - currently seeing as little as 5 hours. On average, 55% of my battery goes to "Android System". I've tried a variety of battery monitors, but none can dig deep enough to determine which of the processes under Android System are sucking up all my juice. I'm on stock (rooted) and have tried to uninstall as much as I can (including the notorious Google+). Any tips on an app that can determine exactly which process is draining? I've also disabled as many Samsung apps as I can. I *did* try CM10 for a bit, but too many small things were not working right, so I nandroid'ed back to stock again.

I had this problem numerous times before. If it is Android System that is taking up battery, then its most probably a bad kernel. Your nandroid backup probably was bad. (it sucks, i know). Redownload the stock rom, flash it in odin, before starting up reboot in recovery and factory reset, then start it up. Your problem should be resolved. dont restore any apps and start fresh. Like I said it sucks but what can you do?

Hey ScottC,
Definitely doesn't sound normal. At the end of the day, I'm sitting around 10% lost to android system, 15% tops (of course this can vary on what you use and how you use it, but if your battery dies in 5 hours, certainly something is wrong). It's possible that in the process of nandroiding back, something messed up. I'd recommend a complete wipe (factory reset, wipe dalvik, etc), then test it out for a day or two. If the issue persists, you will likely want to Odin back to stock. If it still persists (highly unlikely), I'd call in for an exchange. Best of luck to you, and please let us know the results!

Thanks for the tips - to clarify, it was doing this before I ever nandroided back - but I have a feeling wiping might be the best bet (or trying out a better JB leak).

I think you may be getting the gsiff_daemon bug. Next time you have the battery start draining like that, turn on show cpu usage under developer options in settings. If you see gsiff_daemon at the top, then that's what's causing the android system battery suck.
The fix is simple go to /system/bin with a root explorer, mount r/w and rename gsiff_daemon to .Bak or delete it. This won't hurt anything. Then reboot.
There is a thread about this in QA. If you check it out keep in mind it's full of wags and speculation.

I have the same issue. My phone was 100 percent and I've been sitting here watching the Texans game and I'm getting the worst battery life today that I have in my week or so of owning this phone. My phone is bone stock.

Add another one to the list for this problem. I've had my phone since Sept. 27th (so 3 weeks?) and up until about 4 days ago it was great. Great battery life, even with all the bells and whistles turned on, and several apps that update constantly. For some reason a few days ago it started to battery drain HARD, downing to 25% of the battery life in less than 6 hours. That's with the phone sitting idle, not touching it, on wi-fi (not 4G) with excellent signal. Last night I plugged the phone in at 10% battery, did some chores, and returned some 3 hours later to find the battery at 5%. It drained while it was plugged in!
The battery drain issue seemed to start after the phone decided to have a certain level of diffuculty finding a 4G signal. I had to reboot the phone to get it to connect to the network. After that, the Android System will take anywhere from 55% to 76% of the battery drain.
I have shut off numerous programs, disabled the Samsung apps that were said to possibly be a problem, and looked for the gsiff_daemon in the CPU list (my top process is "com.android.systemui"). I searched com.android.systemui to see if I could find a fix, and all I'm really seeing is "flash a new ROM" or "Your kernal is bad, reset or reflash it." I'm running a 100% stock phone, and actually had no intention of rooting or flashing this phone yet, and I didn't want to have to factory default it. It's starting to look like that's my only option. Someone said that this bug seems to crop up out of pure chance and I think they may be right. My husband has the identical phone, bought, charged and activated the same day, and he doesn't have this problem. He's still getting the incredible battery life that I used to get.
So what's the skinny? Is my only option on this a factory reset? I've seen threads referrring to a thread dedicated to this topic, yet no links. If there's more info to be found, I'd love to read it.

This thread might as well be titled "all noobs thread". It is known widely that android system in jb leaks is a problem but of course u cant know that cuz reading and searching are two words that sound like chinese to you.

Actually I have "searched" and "read". I wouldn't have posted had I been able to find an answer. Everything I've found has been for ROOTED/FLASHED ROMs, and I'm on stock. I don't want to root/flash this phone, I'd like to fix it without having to return it or factory default it if possible. I also mentioned that I had gone through threads and tried as many of the tips there that applied to my situation.
While I'm not nearly the level of many here, I'm also not a n00b. I've flashed, rooted and hacked many devices, I'm just trying to avoid that here. I didn't run across anything called "jb leaks" in my search, so if you'd care to be helpful and elaborate on that term, it might prove useful.

I believe this is the thread you were told about.
http://forum.xda-developers.com/showthread.php?t=1755180
When you checked cpu use, how did you check it? There's an option in Dev Options to Show CPU Usage and you can see real time what's running. Just fyi in case you did it differently.

Thanks for the Link, Doc! It's much appreciated. As far as checking the CPU, I used the option under the Dev Options menu and watched it bounce about. Many different programs would take top spot, but when the phone was idling it was always com.android.systemui at the top. When it wasn't top, it was never far below.

Have you tried booting into recovery and wiping dalvik cache?
If it comes to it, before factory resetting since you want to avoid that, download the official stock FW and flash with Odin. I'm pretty sure it will keep your data and apps intact. Backup data first in case I'm remembering wrong. If that doesn't do it then factory reset may be your final option.
Check settings > Battery, and open Android System (I'm betting its at the top). This may give you a better idea of what the root cause could be, maybe...

You are not the op of this thread so i cannot comment about your problems. The first posts regard rooted devices running jb leaked roms and in the jb leaked roms threads all people talk about is android system taking a high percentage of the battery usage. So one must be really blind not to notice what is the problem and fix if there is any. There is no fix and it is kernel issue. Thats the reason why it is called leak and not official release. U can post some screenshots of ur battery usage and firmware version you are running if u want people to help u since u claim u r all stock and still android system usage is high 76%.

Doc-
I tried booting into recovery, but since I'm not a rooted user I can't clear the delvick cache. Somehow in the process of attempting booting into recovery I managed to lose my set wallpaper and most of my homescreen widgets, though the rest of my data and programs seem perfectly intact (accidentally went into a safe mode option). I did clear the cache partition in recovery, and tried another trick someone listed of pulling the battery and holding down the power key (I'll try anything at this point) and oddly it seems to be behaving better so far. Sitting on my desk it didn't discharge at all, and having just put all my widgets back it's only drained a few points. The screen is now the big spender at 39% with Cell Standby next at 12% (previously is was Android System being the hog at 50-70%). I have no idea which of the things I did actually did anything, but I think this just saved my tail.
I'm going to charge the phone normally tonight and leave it loose all day tomorrow like I usually do, and see what happens. If it starts battery draining again, I'm going to try flashing with Odin. Here's hoping I'm one of the few lucky ones where the problem simply "goes away".
Thanks again for your help!

Well that's kinda weird...good, but weird!
I've heard of people going into safe mode but its never intentional and I've never found how to do so at will.
As long as it goes back to normal though! Hope it does! Good luck!

I know that this sounds pretty simple and you may have already tried this, but it always works like a charm for me. Try draining the battery ALL the way down until it automatically shuts off. Then keep turning it on until it won't even turn on our vibrate anymore. Plug it in and turn it on. Leave it plugged in until it's at 100% again, I do this overnight so there's no usage other than standby. Hopefully this will get your battery back in shape. Good luck!

Sometimes I wonder how I got into Safe mode.
forum.xda-developers.com/showthread.php?t=1821557

Well, It behaved for about an hour, then it started the massive drain again. Sadly I just backed a few things up and then factory defaulted it. We're leaving on a trip tomorrow, and I need it to not be a power-sucking brick. Oddly, everything that my CPU report was showing was identical to my husban'd phone, which has no issues with battery life. The Gsiff daemon never once showed up.
As far as safe mode, I held down the volume down button while I powered up the phone. It went into safe mode. Don't know if it'll work for y'all, or if it was just a fluke on my part. :>
Thank everyone for your help in trying to troubleshoot this. One of these days I'd love to have an electronic device that just worked without me having to poke around in it's guts. ;>

If its still acting up after the factory reset, your best bet is to flash the stock FW with Odin. If the factory reset didn't wipe your internal sdcard, you may need to to wipe it in recovery by using format data as well. (Factory reset should do this anyway as long as you're on stock recovery)
I've seen on some jb leaks where this would significantly help. I know your not using jb but its worth mentioning anyway.
Good luck!

[q] at my breaking point with battery drain

I know this horse has been beat to death, I'm just hoping I can get maybe one bit of info that will help me resolve this issue before I just swap out to another phone. I really don't want to, but I'm just so sick of being chained to a charging cord all day. My phone should be able to hold a charge for at least 1 day, I don't even use it that much!
So with my little tirade out of the way, let me give you the facts I've got a Samsung Galaxy S II/SPH-D710, and the battery just drains down so fast, and the phone's barely 6 months old. I've downloaded numerous process monitoring apps, designed to see what's going on, and they all point at WiFi being the culprit. The phone never hits deep sleep because the wireless is keeping it awake. Sure enough if I turn WiFi off and I go 3G/4G all day my battery is fine. Problem is I can't get to that next level and find out what program or process is causing the WiFi to be on all the time. Even more frustrating, every time there's an upgrade like FI27 or FL24 which I'm on now, the battery works fine for a day or two. Then something kicks in and destroys the battery. My thought is it's got to be an app, I just don't know which one.
So before I kick this piece of **** out the window, I was hoping someone could please help me figure out what app/process is the cause of my battery drain.

Get DS Battery Saver. It will force all of your stuff off when you turn off the screen so that it will go into deep sleep.

Get a new battery?

Apps, batteries, ics vodoo it's a host of things that can solve your battery drain issue. Being that your phone is 6 months old I have to rule out the battery. The fact that your on ics is going to be main culprit, stock ics was not the best at managing battery use. There's something revving the crap out of your Wi-Fi, while Wi-Fi is on even while your screen is off there are processes going on in the background that are using Wi-Fi to send receive, update, sync, you name it and all you need to do is pinpoint these processes.
Some apps in the play store can help, but some of these apps can consume battery also, so it's best to delete it after troubleshooting.
If your phone is working properly and your not a social media junkie while it sleeps it should not be using any battery at all, just enough to keep your processor awake.
I keep notifications are sync off on my phone, while I'm out and about I'll check email or do a quick sync if I want to check for some incoming whatever. Most of the time I want info on my terms, not every minute with chimes beeps or lights flashing.
If you use google maps disable background location reporting, location services just use "location and search " disable Wi-Fi and GPS usage for location services.
This is a start, but I recommend Jb ga10 stock/rooted to give your phone a stable os.
I run stock/rooted Jb de-bloated with minimal apps, no games (all the games I like are on my Galaxy Tab 10.1) I use my phone for calls........... navigation and media player while driving. I get 16 to 20 hrs on a charge.

I get about 20 hours on the Vanilla RootBox JB ROM. YMMV. I also had terrible battery life on the stock ROM and every other one I tried. This is the first ROM that's bested 10 hours. Again, YMMV.

what rom are you on? tw? cm?

Have you used Better Battery Stats? Or the JB release candidate GB08?

Not to raise the dead, I've just been busy, but this is still an issue for me. I upgraded to JB GB27, and I love the GUI, it’s such a step up from ICS. But I’m still getting **** for battery life. Yes if I use DS Battery Saver it works and I get good battery life. However all those programs cause flaky restart issues. The phone will just restart for no reason. More importantly it’s not getting at the root of the problem.
IRL I’m a computer tech and I can’t just let this go, as previously stated I’m tired of being shackled to the phone charger. I’ve swapped in a new battery, it’s not the battery. I even turned on the setting “Keep WiFi On > Only when plugged in”. That did improve the battery a little, but I still can’t make it through the day without being charged. I’m on the phone maybe combined 30min of phone calls, 30 min checking email, and an hour or so of miscellaneous watching video etc. I know heavy users that are on their phones all day, or let their kids watch Disney movies all night. I’m not that guy, I’ve had numerous cell phones and never have I had one that couldn’t hold a charge all day.
I will be diligent in monitoring this thread, please give me your troubleshooting tips and I’ll report back with the results.

Downlpaf betterbatterystats. And find the wakelocks.

Can do, will let you know at the end of the day.
EDIT: Actually I read multiple issues with SG2 and BetterBatteryStats. However your wakelock comment made me stumble onto the app Wakelock Detector. Again I'll run it and report back. Thanks for the point in the right direction.

Ive noticed no better or worse battery between being rooted/custom rom and stock not rooted. However my phone gets about 16 hours on average. My friend has an epic as well and gets only 10 hours. I feel as though it depends on the user and apps. Facebook is a silent killer. As is any app that uses backround. Best setup ive had so far is billgeryans Quattro Rom with ds and greenify. I pulled a whopping 25 hour minimal use before charge and 13 hour heavy use day.....

With titanium backup. You can also install greenify. It puts your apps in hibernation when your screen is off. So basically it's like freezing and unfreezing. Tbh I think it's better using greenify.

titanium can and you can create a widget to do it easily per app.
or

or what I do:
shell commands usind connectbot widgets with a command like this:
pm disable-user com.facebook.katana
pm enable com.facebook.katana
---------- Post added at 07:36 PM ---------- Previous post was at 07:32 PM ----------
so my 2 cents:
1) get a second battery and charger.
2) betterbatterystats to identify "bad" apps and either get rid of them or deal with them.
3) "autostarts" app to stop crap from auto starting on boot that you don't need running as a service.
4) dim screen! huge huge savings. keep it dim enough to use the phone.

Battery issues well I have a solution that won't solve but greatly helps. It's called greenify. It puts all running apps in hibernate mode. It's not like a task killer that just screws things up. U can choose what u want to hibernate and all that jazzy stuff. It's worth a shot. All in all if you want a bada$$ battery efficient rom go with wcx stock rooted rom. It's simply amazing. Hope I was at help

Check out greenify if you're rooted. It removes all currently unused apps and processes from memory, essentially putting them into deep sleep. That combined with ds battery saver and watching your wake locks will drastically improve battery life:beer:

[Discussion] Official JB 4.1.2 Stock

K....I apologize if I missed it, but didn't see a stock jb thread....aside from the one from months ago that has a billion posts. I think a new one is not unreasonable.
Anyway... just curious about what others think.
After debloating it heavily....all T-Mobile and Samsung junk gone and a lot more....and stopping apps from auto starting with autostarts...I'm pretty happy!
GPS took about a minute to lock first time ...but now its quick. And accurate.
It is super smooth after a day of settling.
Going on 14 hours on battery with light to moderate use and at 59 percent left. Seems on par with most stuff I've ran.
I do miss some of the customization ...which will lead me to start flashing soon I'm sure. LOL
But overall....I'm impressed.
Anyone wanna share, ask questions or debate?

I had it working once on my T989D, it was heavily bloated, still seemed faster than usual leaked builds. Doesn't really matter now though because I can't flash anything based off this official tmob update because every ROM I've tried with it either bootloops or FC`s constantly. A real shame, I looked forward to this for so long, I assume it doesn't work because I have the koodo t989. Waiting on the Telus version to be released.
Sent from my SGH-T989D using xda app-developers app

I have a T989D also and I've been able to get it to run perfectly fine for over 24 hours.
I have version 1 of Infamous S2 and I had to flash it, wipe cache and dalvik, reboot let settle for ten mins then flash the newest radio or it would keep dropping my koodo radio.
I think the key is wiping cache and dalvik after you flash it, I did also do a full internal wipe and installed from an sd card though.

I didn't see a huge increase in speed. Although it does feel a little smoother.
The increase in battery life has been huge for me though. On ICS I had a terrible average of about 6-8 hours depending on light to moderate use. On Jelly Bean I'm averaging 10-11 hours on more than moderate use.

Do you have a list of what you removed?

I also can't flash any recoveries except the old cwm so that's probably part of my problem.

That's pretty decent battery life and what I used to get when on the stock 4.0.4, but my battery life with this one has been worse. It drops below 50% after 4 hours off the charger with the same amount of use as before. I noticed in a developer thread a screenshot of someone getting great battery life as well. Did you root and debloat?
It seems like the OP was able to do that with some success. I really like the performance otherwise, much better improvement over 4.0.4. OP, are you rooted? Also, I searched the Play Store for autostarts and saw a few different options...would you mind sharing which developer's autostarts app you're using? I saw one that's paid and a couple that were free. Thanks!
EDIT: The other thing that's frustrating is when a new text comes through, it just says "New Message Arrived." I used to be able to change that in 4.0.4 to where the text would display in the notification area, but I can't find that on this version. Wondering if TouchWiz did away with it or it's because of my corporate password policy.

The 10-11 hours is even more amazing to me because I've been using my phone way more than usual (Simpsons Tapped Out is addicting)
I did do a full recharge/drain a couple times after upgrading, so maybe that may help you.
These are my steps in case you want to give it a try.
(On a full charge 100%)
I used odin to flash back to ICS stock unrooted
I then used kies to upgrade to JB
After the upgrade, I went into recovery and did a wipe/factory reset for good measure.
Unplugged phone and started setup (Disabled some tmobile bloat)
Used the phone until it ran out of charge.
Charged the phone completely .
Unplugged and drained it completely again.

K....not gonna quote a bunch of stuff....but in response to a few things.
This was my experience, but trying to use the tlle4 Telus radio left me frozen at bootup mostly....I got in a couple times, but it wouldn't let me save my apn settings and I had no signal. Flashed the new jb radio and manually had to enter apn settings, which saved this time...and I was good. Tlle4 has better signal where I live, but the new one works OK.
What did I freeze? Well, mostly anything with T-Mobile or Samsung in its name. Now everything is working fine, so soon I will uninstall and delete them completely.
I use the app specifically called Autostarts. It is a paid app....but gold to me. I stop any app I am familiar with and don't want starting by itself at startup or other events. Especially maps!! Otherwise it seems to run all the time. I disable it in autostarts anywhere I find it. Then it only runs when I start it.
Think I got most things that were directed to me covered.
I also use advanced task killer free. I do not ever autokill apps. I use it as an easy way to kill things after I run them that don't close properly by themselves. Like maps and Canada's the weather network app.
Last night when I plugged in my charger I was at 24 hours and 3 hours screen time with 22 percent remaining. So stock seems no better or worse than most other jb roms I've used.

It seems like the OP was able to do that with some success. I really like the performance otherwise, much better improvement over 4.0.4. OP, are you rooted? Also, I searched the Play Store for autostarts and saw a few different options...would you mind sharing which developer's autostarts app you're using? I saw one that's paid and a couple that were free. Thanks!
EDIT: The other thing that's frustrating is when a new text comes through, it just says "New Message Arrived." I used to be able to change that in 4.0.4 to where the text would display in the notification area, but I can't find that on this version. Wondering if TouchWiz did away with it or it's because of my corporate password policy.

The new message thing was bothering me too. After seeing your post I looked more closely at the settings. Open Messaging and then open the settings. Under notification settings check preview message. Now the text will display in the notification area like before.

The JB this phone got is crap. Doesn't the same phone for att Skyrocket get ripple lock screen and multi window? Also we can NOT download the voice files for offline voice recognition.
The Skyrocket port of JB for this phone can do all of that.

I'm using the Embryo rom now. I did try installing the new stock JB rom but it just can't compared to some of the custom roms. I haven't try the roms by ptmr3, Rushing, and Jamison. I'll probably wait for a few more updates before trying the tmobile JB roms. I missing using Wifi-calling sometimes but the Embryo is just a very good rom.

Cyanogenmod 10.1 terrible battery life

I have recently installed cyanogenmod 10.1 onto my galaxy s3. The battery life since then has been very poor. If I leave my phone on without even using it, it drains about 1% every couple of minutes. When I look at the battery it says that the process of "phone" is taking up a huge amount of battery. Can anyone tell me why this is or how I can fix it?

Generally these issues are user related and not ROM related.
I was so frustrated with some of the ROMs when I first started out but then realized I was doing a few things wrong (mainly because these ROMs, including CM10 have very decent battery life).
First, I would recommend a clean reflash:
factory wipe / reset
wipe cache (some say twice)
wipe dalvik cache
install ROM
after rom loads, wait 5 minutes (don't touch at all) then reboot
now you must wait.. sometimes it takes 24 hrs or so for a ROM to correctly load.
Not sure how true it is, but some say to now drain battery down, then fully charge.
At any rate, I follow these steps all the time and works great!
Also, keep in mind that most of battery issues are user related.. so think about what settings, apps and kernels are being used on your end before question a ROM. This is why waiting 24 hours or so before installing all of our "crap" will give give the ROM more time to settle.
Hope this help!!!! Happy Flashing

Thanks for the reply. However, I have looked at what apps and processes are draining my battery. And it appears it is the "phone" process that is doing this.

Just to piggyback on spenny88's reply, exactly what did you come from (stock?) and how did you wipe and flash?
This is all key as to how well your device will perform.

I have noticed something similar. I am coming from stock. I am going to guess my battery life is in the neighborhood of 10% less. I wiped everything before I installed CM. That said, this feels so much faster than stock.

Having the same issue with my Samsung Galaxy Tab P1000 (p1 in Cyanogenmod). "Cell Standby" is taking as much juice as "Screen", and I am using Wifi only. I don't even have a sim card in the device. Wish there was a way to disable Mobile Networks without disabling Wifi via Airplane Mode.
I installed through Rom Manager as upgrade from CyanogenMod 9.1 with wipe. I will try the recommendations above and report back.

Try the latest nightly (or RC4) of CM10.1. The battery life has definitely improved a bit.

Samsung Galaxy s3 intl battery drain cm10.1
I recently installed cm10.1 nightly on my international S3, it has cut the battery life down drastically and seems to drain over 10% an hour, even when not being used.
I've tried everything that i've came across by searching and still haven't had any real gain on battery life. Doing a full wipe and reinstalling doesn't help, and i've given it time for battery to calibrate; no difference. Even with wi-fi and location services off i'm getting a big drain. I've even tried switching to Slim Bean, if anything the battery was worse still.
Firstly i'm getting that Android OS is eating up a large chunk (usually above 60%) and using BetteryBatteryStats i don't see anything out of the ordinary in terms of partial and/or kernel wakelocks. I really don't wanna have to put the stock Touchwiz rom back on but that seems like the ways it's going. Any help would be greatly appreciated. Is there anything else i can try?

i find i get terrrible battery life on AOSP when i restore google through the setup. i skip thru the installation and open the play store to enter my gmail. then, before restoring my apps, i let it charge to 100%. honestly AOSP still doesnt have decent battery life, but it does improve if you play with it and try different things

I would respectfully disagree with you. I have run a number of ASOP based ROMs and find them better than stock in terms of battery life. Certainly better in terms of not making my eye bleed (as I hate touchwiz, but that is a personal preference). I find that SlimBean gets me the best battery life of the CM based ROMs.
To clarify, I get just over 1%/hour battery drain, when idle (as measured by BBS) with GPS and google sync enabled, mostly on LTE. My phone happily spends almost all the time I am not actively using it in deep sleep.
The recipe to achieve this is to disable google location reporting and history, avoid tons of widgets that constantly update themselves, disable samsung services that you do not use, and monitor battery usage to look out for rogue apps that do stupid thengs, like hold wakelocks when they should be idle. Dropping the minimum frequency to 192 MHz, and going to ASSWAX (CPU scheduler) and ROW (I/O scheduler) also helps.
To get decent performance you do need to install things properly. Which means ensuring that you don't have conflicting settings or random leftovers. I tend to dirty flash updates but you reallly do get better and more consistent performance going through the pain of a complete clean install (format system, clear cache, reload apps from the store) when you are switching ROMs. Only use TiBu to restore app data. Once you do this, in my experience rogue wakelocks are the biggest cause of lousy bettery perfromance, and you can track down and eliminate these. I have around 150 apps loaded and do not run any task manager/autokiller. My phone typically runs without any reboots or power cycles between ROM updates which equates to rebooting every couple of weeks to a month. I have seen over 2 months of uptime.
Certainly should be able to go 16-20 hours between charges which I would consider real world all day functionality. I guess my point is that rock solid stability and all day battery life is possible if you are systematic about how you do things.

Battery Life Issues

Scenario:
Yes, yes, I know. Battery life issues. This is a common problem, noticeably on the Samsung Galaxy S3. However, I've taken a look at MANY MANY threads concerning this common and irritating issue. I always ensure that my data is off, wifi is off, airplane mode is enabled, power saving mode is on, sync is off, brightness is at low, etc. I've even gone to the running services section and manually stopped unnecessary processes. However, my battery life is still terrible. I've tried different roms, different kernels, and eventually found myself back at the stock rom and kernel (best stability). I've debloated my device. I even downloaded a bunch of useless battery saving apps that don't do much apart from the obvious. Is there anything I can do? I will be putting up screenshots of my battery stats.
Usage;
I am a typical user when it comes to smartphones. I browse through xda forums, watch some youtube videos, browse the internet, play a few games, and soon enough the battery begins to plummet. I've noticed at times that the phone gets hot. I have a general knowledge of the things that drain my battery the most. After looking at the battery stats section that comes with phone, it says that Android system, media, and screen use the most battery. Whats the point of having a smartphone if you have to tweak almost everything just to allow your phone to last one day?
I am thinking that there are certain background processes that are dramatically draining my battery. I don't have many apps installed, because I am always flashing roms. I've wiped media storage data, by the way. Some apps that I have installed are the xda developers app, dolphin browser, rescan media root, root browser, rom manager, DS Battery Saver, and lux dash.
Extra: I've debloated (still some left over garbage stock apps leftover but not much, and does it actually help?), I've installed lux lite and lowered my brightness to the point where you can barely see the screen, and I've also downloaded rescan media root and disabled media scan (I heard it has some effect).
If you have any suggestions, please post them. Thanks for reading my thread.

TL;DR all the way since there is no numbers. We need numbers and better yet wakelocks. The info you state sounds like normal usage that should get about 2-3 hours screen on time, and 16 hours or so day usage. You say you turn off data, and wifi, and put on airplane mode, and stuff and yet you use the phone normally?? Either way give us screen on time and the main users, and the graph.
Furthermore, no need for duplicate threads....

I'm going to charge up to 100% and then when I get to about 50% battery life or so I will post screenshots. As I stated in my first post, I acknowledge that there are many battery problem threads out there, but people also say it can vary from phone to phone, and I will soon post screenshots so that somebody can at least tell me what is causing my battery drain, specifically and what I can do about it.
If anybody feels that this is a duplicated thread, please refer me some links or useful threads that I can look at.

Should I just leave it overnight and then post bbs log tomorrow?
Btw, should I install ktweaker so that I can set governor to conservative and also tweak some settings or should I leave it alone?

Also if you really want reliable results, either run the tests on the primary rom you will be using or run on stock rooted. Dont debloat because it can be very easy to remove something that could impact performance. You can do that after running your tests and gathering data. The further down you run your battery, the more reliable the data btw.
This hasn't been much of an issue since JB came out, but if the media scanner is using a large amount of power delete all your media content from both internal and external sd cards. Clear data on media storage (factory reset preferred) and run a day w/o the media on your device.
As stated above though, BBS screenshots are needed for further help.

No.
Charge it up before you go to sleep. Unplug the phone, turn off the display, and let it sit idle while you sleep for at least 4 hours. When you wake up, open BetterBatteryStats, and press the share button on the top right. Dump to txt file and post it here.
If you give BBS root access, and set it to show alarms (in the advanced settings), that can be helpful also. It's better if you can do this, actually. Then run your test.

I was referring to you making two posts about the same thing. As you're already aware of since you acknowledged your mistake here
and tl;dr is Too Long Didn't Read... just cause of the fact that there was no numbers to look at. Looking forward to seeing what your issue is tomorrow. Hopefully it might just be a bad battery.

Yeah just reset to stock and just doing some daily browsing on phone. Btw, on bbs, there are multiple graph, (processes, wakelocks, kernel wakelocks, other, alarm wakelock, etc) which one(s) should I post?

I left it on overnight, battery only drained like 4% so I don't think its a problem when its in idle. As of now I am testing how long my battery will last with moderate usage. I'm hoping it will last at least 24h its been 10h and its at 79%. Its that good? I've mostly been listening to music, I haven't opened any apps. Only problem is whenever I am on xda or playing a game, the battery seems to drain like 1% every 5-10 min. Is this normal?

Just leave BBS running all the time. If you have any more problems, I think you know what to do

This is exactly what I was expecting the whole time, normal usage and normal battery drainage.

Have you seen this? http://www.jeffmixon.com/examining-build-prop-tweaks-for-android-ics-a-comprehensive-guide-part-1/
Most of the battery "tweaks" in use by custom ROMs are in there. And I was running stock deodexed before S3Rx and ultimately Dandroid. Battery is always good as long as I run LJC firmware.

Just took a quick look at it, looks pretty complicated for me. What exactly is the difference between deodexed and odexed anyways? I've heard of both of them but never really understood what they were. Which firmware do you run on currently?
For the firmware are you referring to the 4.1.1 JB firmware T999_UVDLJC?
