I've been trying to troubleshoot my battery drain rate and I found the problem.
When I turn off the GPS, and leave the wifi and bluetooth on, I get tremendous battery life/
What could be causing the GPS to drain the battery?
Do you ahve any programs running in the background that use gps? such as latitude, or that google one that maps your location? If so, gps kills batteries, because it constantly resyncs with the satelites... I believe the sense weather app also does periodic polling to pinpoint your location for weather.
If you dont need GPS exact location tracking, dont leave gps turned on, and turn it on when you need it.
My GPS is always on. It doesn't really hurt the battery life unless you are using with an application that uses the location service. My weather widget is set to refresh every hour and it's not impacting the battery.
I would look at your running programs and figure out which one is using the GPS. If you have the sensorly 4g map viewer, I found that to be a battery hog.
My money is on Latitude, that's been implicated in a lot of these situations. GPS always on is hardly a battery drain unless something is actually using the receiver. If you don't see the GPS icon in the notification bar, it's not GPS-ing.

Interesting tip. I had not noticed it. Thanks.

I have my GPS on all the time and I regularly go over 13 hours without recharging; this is before SetCPU and underclocking.
I open this thread to help the users having bad battery life and find out the possible resolutions. Whenever you see the bad battery life, in most of the cases it would be caused by some specific apps or the way you are using the phone and it's not from the ROM itself.
As you may know, I'm working on Kobridge Tweaks and trying to improve the performance and battery life but there're lots of variances that we still don't know and have to know.
So, let's work together to find out the better solutions!
In here, please share your screenshots and your settings. But, don't post with just simple words - it's good or it's bad. We need the following information when you post;
1. Your ROM related info - Rom name, version
2. Kernel/modem version
3. Any additional apps installed
4. Any tweaks that you did by yourself
5. When you post, please add the screenshots -

Kobridge - General Settings to extend the battery life
General Settings or Configuration to extend battery life
This is an initial edition. I'm going to update and add more information here.
Original post - http://forum.xda-developers.com/showthread.php?t=1625299
I've worked on this part so long time since I've started using ICS ROM. I also tried almost every battery saver apps but didn't get any better result using my own method because sometimes there are lots of overheads using it (I'm trying to avoid describing any individual app's pros and cons in here and just provide you the better way to configure your phone).
The information in here is based on FF18 rooted stock rom/modem/kernel. But it's not limited to any specific phone or build. You could probably use it in any phones or builds.
1. Wifi
Some of you understand that wifi is faster than 3G and use less battery than 3G. You also say that 4G is the biggest monster consuming lots of battery. But that would be true and false.
Sometimes, wifi uses lots of battery to get the faster speed and keep the connection.
There could be multiple scenarios in here and below is based on my test -
Original post can be found in here
WIFI - I always turned on at home (because wifi is available) with 'never' option. In this case, 3G will cover the data communication if 3g turned on during the deep sleep. If wifi signal is so strong, even you don't need to turn on 3G and use the wifi during the sleep mode by changing the wifi option.
If you don't need the data communication during sleep mode, then turn off 3G and make wifi sleep (never) during the sleep mode. With this option, your battery could last about 2 hours per 1% drop.
3G - you need to compare between 3G and wifi. Which one is better and use less battery based on the signal strength.
For me, I'm using both 3G and wifi turned on. Using these two options turned on, I make the data communication available always and these two are compromising each other.
OK, here are some screenshots from 3.4M (check the original post link above). From 100% to 65%, I turned on 3G, so it covers the wifi when wifi sleeps during the deep sleep. From 65% to 45%, I turned off 3G, so during the deep sleep, both wifi and 3G were not available. When screen turned on wifi only came back (if you are not a heavy user, this method will save lots of battery).
Based on what I said, I've tested couple of things-
1. Battery life when wifi turned on 24x7
2. Battery life when 3G turned on 24x7
1. When wifi turned on 24x7 (turned on even screen is off), my phone shows that there were about 2.5% drop in every hour (100% > 73% about in 9.5 hours)
2. Wehn 3G turned on 24x7 (no wifi, no 4G), the battery consumption was much slower than wifi. (73% > 62% about in 14 hours). A little more than 1 hour per 1% drop.
Based on my test with minimum wifi, 3G usage, it shows that 3G saves a lot more battery during the standby mode. This result could be different based on your area and signal strength.
Now I showed many things related to wifi, 3G and how it affects the battery life.
Only one thing that I did not test is 4G. It's really hard to make a test using 4G inside of my office because I don't have 4G signal at all. What I can try is, 4G random reboot issue. I'll try to turn on 4G and see if it happens....
2. 3G
Keeping 3G turned on is a good habit. Because it covers wifi and 4G whenever those are not available. 3G uses battery a lot less than wifi and 4G (it could be different based on your signal strength)
Howto keep it on: setting -> more -> mobile networks -> check 3G DATA
Like I said before, if you have a reasonably good 3G signal, then you may want to turn off wifi and 4G to save the battery.
3. 4G
Just like wifi, minimize turning on 4G network. This use a lot of battery if you are in the bad reception area. If the signal strength is really good, then it would be probably ok keeping 4G turned on. In some cases, 4G would be the only solution to watch the movies, streaming videos when the wifi is not available.
Based on my limited test, using 4G in good reception area is much better than using wifi with low/weak signal.
4. Call option
Mark checkbox for Turn on proximity sensor for your convenience even there would be a little battery drain. But if you are a heavy talker, then I recommend to uncheck this option and use the power button to go back to control mode.
5. Sound
Lower the sound/vibration level within the acceptable range for you. There would be some differences on battery behavior by turning off or on of sound/vibration. But I don't want to recommend anything in here because I don't want you to lose any incoming calls/messages/etc.
6. Display
Automatic brightness should be fine in most cases. It's really related to screen on time battery consumption. I don't want to deal with this option at this time.
Pulse notification light, display battery percentage - turn it on or off based on your preference. Battery consumption by turning on these options would be minimal. I saw that some people said that they recommend to turning off the 'pulse notification light'. But I don't agree with that. One blinking LED light almost does not use any battery!
display timeout - I set it with highest value provided. After using the phone, I manually press the power button to go to sleep mode. With short timeout value, I have to keep press the button or screen to keep the screen on. I don't like this method.
Turn on 'Auto adjust screen power'.
7. Power saving mode
I always keep this option off because I do not want to lose anything because of low battery. I would rather change the numbers in my tweak (battery profile 2 in scaling tweak).
8. Account and sync
Most of time, I keep this option turned off. This would be one of the battery eating monster. I would rather individually sync the apps whenever I need it or from the actual apps.
9. Battery
when you charge the battery and phone shows that 100% charged, unplug the cable few seconds and plug-in again to charger. Repeat this couple of times and your battery would be really fully charged. Many times, even phone shows 100% charged, it could be the minimum 100% range. Actually, there's some voltage allowed and considered as 100% charge. But by maximizing the voltage during the charge, your battery life could be extended.
10. Motion
Turn off this option if you don't need this.
11. email
If possible, turn off the option that pushing email immediately. Instead, put the retrieval interval as long as you can. Based on my test, it could extend your battery life as maximum as couple of hours. In my case, I put the 2 hours interval. By doing this, your phone is much easier to enter the 'deep sleep' mode.
12. Startups
For me, I don't allow the apps automatically start during the boot as much as possible. If it's the system app and critical app for the phone's normal operation, then you have to allow those startups but otherwise, you can disable the startup apps based on your test.
For this, I usually use Rom Toolbox and/or System Tuner Pro. These apps allow us to enable or disable the startup apps.
For any apps like I don't use frequently or at all, I disable the apps from the 'event' (rom toolbox) or startups (system tuner pro). Once you disable the startups, you may need some test to see what happens when you manually launch the apps. If your app does not start normally, then go back and enable the event again.
There's also one more battery eating moster - widgets (currently doing some experimental test on it)
Regardless of widgets are in foreground screen or just stays in widgets folder, almost same amount of battery could be used by widgets to make it upto dated and refresh the connections, etc.
So, if you don't need the widget or don't use, go to (from Rom Toolbox) Auto Start Manager -> Applications -> select app you want to check -> it will show that widget updating is enabled or not. If it's enabled and you don't want it, just disable it. Then the app is not going to use that specific widget and actually widget will disappear from widgets folder.

It's not that the blink uses battery, it's that the blink causes your phone to wake up from its Deep Sleep and use the 200 MHz state of your processor. This wakelock takes away battery.
Thanks for the guide though. Looking forward to getting better battery life. I'm currently on CM9 though so I can't use your tweaks Just waiting for an AOKP build that switches /emmc and /sdcard back around to the way it should be
Edit: Just got System Tuner Pro... seems very complicated but I followed your startup advice
Per OP's request. Thread closed for now.
I have a T999V (Wind Mobile) running TouchWiz 4.4 (with towel root) on the Wind Mobile network. This phone has a brand new Anker 2200mAh battery.
Unfortunately, my battery life is under 9hrs. I get about 2hrs of screen on time, which consumes about 20% of battery, and then the combination of Android System, Android OS, Google Services will consume a whopping 50% battery.
I have Wakelock Detector, BetterBatteryStats and GSam Battery Monitor installed.
How do we diagnose what's causing this problem?
I'm usually at home, using my home WIFI. Other issues I've noticed with my phone are that I notice slowdowns sometimes with Swiftkey, when a lot of app updates are going on, Google Maps, Google Chrome address bar. This phone did have water damage at some point and I had to have the power button replaced. Could this affect the battery drainage and or the slowdowns?

Thats about what I get with a new stock battery. If I leave it on and roaming all day while at work and I get no signal, I'm down to 40%, few hours of screen time. airplane mode all day at least gets me to 60-70% by the end of the day.
Is what it is. lol. Plague of all smartphones.
you can't expect a good battery life that you desire. because samsung s3 has a powerful CPU, and a good high resolution screen which will take power to run. You will be lucky to get about 5 hours on a stock battery. If you really want to do stuff.. try under clocking the CPU too 1GHZ or below. that would probably give you 1-2 hour extra battery but other than that..
Try the basics: - GPS off, location off, Data off. etc.

Dude, your battery is normal, we all have the same or similar battery time.
If your concerned with battery life, try an extended battery..
In 3hrs I've used 70% of the battery with 2.5hrs of screen on time. I find it hard to accept that this is normal for these phones.

What were you doing during those 2.5hrs of screen time? With wifi or 4g on, I can kill mine in a few hours, with a new battery. Don't know what you expect.
Disable Google now from the app settings, in WiFi advanced settings make sure 'always scanning' is disabled, only sync what is necessary from the accounts section in stock settings app, only enable WiFi, Bluetooth, etc, when you use it.
First, bigger battery: http://www.amazon.com/dp/9838427837/
Second, Turn off background WiFi scanning (in CM11, Settings / WiFi / ::: menu (lower right) / Advanced / uncheck Network notification, uncheck Keep Wi-Fi on during sleep, uncheck Scanning always available)
Third, Deny wake rights for Google Play Services (in CM11, Settings / Privacy / Privacy Guard / ::: menu (top right) / check Show built-in apps / long-press Google play services / scroll down to Wake up and Deny , scroll down to Keep awake and Deny / BACK once / long-press Google Services Framework / deny Keep awake )
That'll get you 2 days in MY usage
i cant decide if i should keep my GPS on or off, if i keep it off apps like lookout will not work in case i need to locate my phone if lost, how do you keep your gps on or off?
On. Always.
on, all you are doing is allowing gps to run when needed. the only time it is on is when you see the location notification.

Depending on your other apps, GPS can either be a light nuisance (getting location takes an awfully long time) or a complete battery destroyer (apps which use the location feature too often.)
Definitely off, if you care about your sanity or battery life. "Battery saving" location option is more than adequate for most everyday tasks.

I always have my GPS off unless I need it.
I can't tell the difference on my battery life weather gps is on or off so mines always on
Keep your GPS on and in battery saving network towers option. If you have apps that look for location like a weather widget, they will actually use more battery trying to find location with GPS off than leaving it on.
My battery will completely drain after <10 hours while the screen is off!
However I was able to find out thatquickgooglesearchbar is always the top app.
Those screenshots are a bit old but it's still the same thing, I did manage to root it today, and I was testing Greenify which did nothing even with the Xposed modules, service disabler apps just did not show that specific service for some reason. I was able to remove the widget with Xposed GEL settings but it was still running even though the widget wasn't there.
So can someone please help me out here, maybe the search bar isn't the problem but I just want some battery life.

search and install betterbatterystats (read the whole first post) and it will tell you if its wakelocks etc.
Service disabler apps will need a setting to show system apps (or something similar) ticked or switched to etc.
greenify system apps in greenify also needs to be selected. You may also need to cut wake up paths to get it to stay greenified.
You could alternatively delete the apk of hibernate it (byfar the easiest option of all this).

Your 3rd image shows googlequicksearchbox had 370ms (milliseconds) of wakelocks over a 9hr period. I really doubt that is your issue.
If it is your top app, then it is probably because of Google Now launcher listening for OK Google spoken keyword.
I seriously doubt that is your battery drain problem as almost 90% of people probably have OK Google turned on and are using Google Now launcher and only a very few have serious battery drain.
BTW wakelocks aren't the issue usually. In the past it has been "partial wakelocks" which means an app locked the device from sleeping, but never released the lock, so the device never goes to full sleep. If you see some app with partial wakelocks or if you see some app with hours of regular wakelocks then that might be an issue. Minutes or microseconds of wakelocks are inconsequential.
I suggest you flash factory image and install your battery tester only. Turn off wifi, bluetooth, nfc, cell radio. Test the drain overnight. That is a baseline for the minimum drain your device can have. Then enable what wireless stuff you normally have turned on. See what that drain is. Then start installing apps and see what that drain is.
If you have reasonable/expected battery drain with stock and everything turned off, then it is just a process of elimination to see what is causing your battery drain.
If you can't get reasonable/expected battery drain with stock and everything turned off, then you probably have a bad battery.
For the record, my overnight battery drain with everything turned off is 0-1% With wifi turned on about 1-2%. With wifi+cell about 2-3%.
IMO the biggest drains for standby are wifi and/or cell signal related. Either bad signals or apps sending data in background or apps that are polling all the time.

Factory reset didn't do anything a few days ago, the results were exactly the same that was when my phone wasn't rooted, so I guess I should return the phone, and get a new one?

What is your battery drain per hour with nothing installed and all wireless turned off and everything stock?
I'd only return it if that is significantly more than 0-.2% or 1% every 5 hours.
Otherwise it is something you have installed or something to do with the signal and how it interacts with your phone.
Once you start installing stuff or turning on wireless (wifi/bt/cell) then it is no longer purely about the battery and there are more factors that need to be isolated independently.
You really need to establish a baseline to see what the minimum battery drain is. Then you can determine if the battery is the problem or something else.
If you just install everything and turn everything on, there are too many moving parts.

Which battery life was the one you think you have a problem with, standby or in use? IMO for in use battery time this phone is about average. Your title of "wakelock" made it seem like you were concerned about standby battery time as it doesn't matter if there is a wakelock if the device is already turned on and in active use.
When turned on, the screen is probably the number one thing eating power, so adaptive brightness could help, but if you are in a bright area, it might be worse than if you fixed the brightness below max.
Even if you have adaptive brightness turned on, the slider scale still is useful as you give the adaptive brigthness mechanism some idea what level of brightness you feel comfortable when the mechanism detects dark, med, bright situations.
One of the worse things for eating power is for the cell radio to be turned on but have no signal, like inside office building or just a bad signal area in general. The reason is the cell radio is power efficient once it establishes signal, but when it is searching for (or loses) signal it uses a lot of power.
If you are doing a lot of disk activity like taking video or hdr pictures, it would probably help to have your userdata unencrypted as this device does software (kernel) encryption and doesn't use the fast/more power efficient co-processor.

Standby is the problem, on screen times are good enough.
Anyway, I don't even know what to do at this point. Android N didn't help enough (cell data is off), I guess I can flash Android 6.0 again and then try to fix it using apps...
What do you suggest I should do, I'm out of ideas at this point.

What is the power drain over a couple of hours with *no apps installed* completely stock, and wifi/cell turned off? What is the change when wifi is turned on?

Have you set "WiFi on during sleep" to "Never"? in the Advanced WiFi settings?
In the original release, there was a bug where WiFi would stay on even if you had set it to "Never" draining battery in standby.
Somewhere between MDA89E and MHC19Q they fixed it and WiFi will go to deep sleep after being in standby for a while, but they introduced another (or exposed existing) bug where WiFi will not resume after coming out of sleep, unless you cycle WiFi off/on. So you're standby battery should be better with this setting, but it'll be a little more annoying when turning on your device.
