no battery life with the 2.2 update

My battery made it to 1:00 o'clock today with the new 2.2 update that i did last night. It normally lasts till 11 - 12 at night. Whats up with that?
FYI - All the same apps,widgets, and settings
**UPDATE**
Doing a factory reset fixed the problem for me!!

Strange, I'm sitting at 75% after 5 hours off the charger and using it for moderate text usage (probably less than 80 messages today). Usually around this time it's sitting closer to 60%.

i have the .3 update and went from about 24 hours to about 8-10 hours. Battery life cut in half. My friend who has .3 is having same issue too. So much for increasing battery life.

Wow. Have you searched the forum to see if anyone else has the same issue? If not I hope it's not an isolated incident. Then again if it's isolated maybe you can get support on it better...? Good luck finding a solution.

You gave us zero information to help you. So thus, you will not get any help.
There are about a billion threads on here about battery life and how to tweak it. When you flashed 2.2 you will need to do those steps again.

yeah some people are reporting bad battery life after update. most people i know are on .3. don't know if .6 fixes this hopefully we get update soon

I did a test last night. Dropped 13% between 1130 and 3:30am With wifi on (got up cause of baby), then only 10% between 330 and 8am with wifi off. So a drop of only 23% overnight.
That's with one exchange account, one gmail account (both syncing as items arrive), htc news set to not sync, but newsdesk and feedr both syncing. Facebook for htc set to sync contacts only.

I had the same issue on all 2.2 ROMs I tried.. i am now going through the apps one at a time to see which one is the issue.
right now I am 7 hours in and sitting at 75% very light use ( read about 7 emails, 5 new articles and little to no Web surfing). installed 10s so far other than the standard with Fresh latest ROM that is.

I've actually had very good battery life, I'm running the .3 release. Battery life for me has been very comparable to running Baked Snack 9.6, with its underclocking/undervolting power save features. Moderate use of the phone for 8 hours (wifi, browsing websites here and there, one navigation route, texting, bunch of short phone calls, playing some games), my battery was around 65 or so, same as I had before for similar usage.
I did do a full wipe though, and haven't calibrated my battery since updating.

I am just stating a observation on my part. And i know all the little tricks of how to get better battery life. But like i said, before the update i was getting a full day of battery and now after the update i am getting half. With the same settings and the usage on my part.

maybe because some of the htc sync stuff that you might have disabled before re-enabled.
Check that.

This is not directed at you personally, but at the words you chose to use:
I am sick and tired of "tweaks and settings and cutting things off." I used them and got over 30 hours on both DamageControl and Fresh.
I paid Sprint/HTC good money for this awesome phone (and am committed to pay them a whole lot more over the course of the next 22 months).
While I can understand the 4G thing, why should I have to cut off Data-WiFi-Bluetooth, power down the CPU, not use it a lot in order to get... in short, drive it like a Toyota Prius when then phone is billed as a Maserati? Why should I have to try out this app and that app(Overclock widget, SetCPU, System Manager, Task Killer, Autostarts etc which all use battery too) in order to get the phone to do what it should have done on June 4, 2010?
Most of the battery draining apps and widgets come pre-loaded with sense (i.e. the Favorite widget, Friendstream etc). Why should I have to resort to rooting my phone or not using it in order to get the thing to last all day?
I'm keeping my EVO cause I love the device, but maybe Sprint/HTC need a little of the medicine that Jobs/Apple is getting in the form of lawsuits due to over-promising/under-delivering.

You should send that rant to HTC and Sprint... I think we all stand behind you on that one.

there are lots of reasons a battery might not last. there are way to many tweaks out there which is why you have to do it yourself.
First set the phone up like you normally have it and test the battery life. if you can live with it your good. if not start looking at the settings. Read the tweaks but don't just take them as golden as everyone is different and uses their phone different. Ask yourself if you real need that setting. (I like my screen time out at 2 min. do I need it NO 1 min is fine). When done with the settings move to the apps. load the flat ROM no apps and run for a hour and track your battery life. then add the apps 1 at a time or in small groups and let run an hour and track. there are was if find what apps are using the CPU or Battery but many do this normally and yet don't effect the battery much. Only way i have found is old school add them one at a time. When you find a bad one decide if you need it or can find a replacement.
I am done with Sense as Launcher Pro Plus is awesome and now with the only Widget I was missing (Calendar). Once I done going through my app list I will create a new thread in General to list the bad application I found unless someone else has or does before I done that is.

From what I have gathered from using .3 that apps auto sync/update on their own now with "always on mobile data" turned off. if you use advanced task killer, do a kill of all apps then turn the screen off. If you wait for a few minutes and turn the screen back on you will notice that apps like news, messages, Twitter, Facebook clock, weather and others will be active. From what I gather the decrease in battery life is from apps like those will send/receive data on 2.2 while on 2.1 apps would not update/sync until you manually refreshed or opened the app, as long as you didn't have "always on mobile data" enabled.
Edit: this reason is why I uninstalled fring. Just too bad I cannot uninstalled qik.

It is a mini-computer. You don't use it like a "phone" anymore. You shouldn't expect more than 15-20 hours on it. Do you get angry when your laptop runs out of life after 5-6 hours? If you don't want to do tweaks, then don't. Keep a micro-USB at your desk at work and charge it there. I, myself, enjoy rooting so I don't mind tweaking it. I also get 30 hours of life on it due to this. If you don't like to do that, you get what you put into it.

Again, you have unrealistic expectations for a smart phone it seems. All I have is Set CPU running on my phone with Fresh 3.0.1 and works just fine. I still use my phone like a "Maserati", it just lowers the CPU when the screen is powered off. That is like saying you want your car to idle when you get home at night until the next morning. It doesn't change how you drive it, just how you store it in the garage.

You don't have to use them though. You can remove friendstream and go with either the twitter or FB update app or go without either and just check facebook like anyone else. As far as favorites go, you don't have to use that either. You can just make shortcuts to each person's phone number on that same screen if you think that is sucking all your battery life. There are always other options or fixes, but again you expect the phone to come out of the box perfect without any customization. You are getting away from what Android really is. Something tells me the Iphone would have been more your liking since it is built around lack of true customization. This isn't a rip, but just saying if you want cookie cutter phone reliability, it is hard to beat Apple. If you want the ability to tinker with the phone, the power to change things, and the power to make your phone yours, then that is more Android.

I can understand your frustration, but nothing was ever promised to us on purchase. I don't remember anywhere seeing something saying the battery would last 30+ hours out of the box. Apple had an actual structural issue with their phone, that is why they had the lawsuits and PR nightmare. This is just the phone doing what most would probably expect(at least anyone who had a G1 or Hero or any of the earlier Android phones). You love the device enough to keep it even with your frustration, something tells me it works quite well for you. But I have yet to see any over-promising/under-delivering on the Evo myself.
And no, I don't work for Sprint or HTC. And no offense meant to you as a person, just I didn't understand your motives on your frustration. Guess we will have different opinions on the Evo so far.

I had the same battery problem after updating to 2.2. After 3 hours my battery was at 50%. Normally it'd be at 50% after 9 to 10 hours of usage.
I did find that some settings had been reset. Once I turned off all the crap syncing, gtalk logging in, Sprint Zone, etc my battery usage has seemed to flatten out.
I made it an hour and only dropped 2% which is much more like it. This is all with very little usage going on.

Buy a new battery! Best solution!
No joda!

The saga of the GS2 and the iPhone 4

I bought a SG2 some time ago and loved it except for the idle battery drain. For the life of me, I couldn't seem to get it to stop chewing battery when it wasn't being used. I even tested it by charging it to full and leaving it overnight. It lost about 20%.
Remembering that the iPhone 4 had excellent idle battery life, I decided to give it another go just for the hell of it. I hate iOS as a daily driver, but I figured at least I wouldn't have to worry about battery life.
These are my observations:
1) Idle time on iPhone 4 is indeed better. When it's not being used, it uses no battery. However, when being used heavily, the SG2 actually seems to get BETTER battery life than iPhone 4 when it is being used heavily. Not sure why.
2) I severely miss being able to send/upload high quality videos and pictures. I hate the restrictions that Apple places on file size. I don't always have wifi readily available and at least with Android, you can upload large videos to Youtube over the cell connection.
3) I miss the integration in the photo album with social services. It's annoying having to launch an app every time I want to upload a picture/video.
4) The camera on the SG2 is definitely better. You get more fine detail on objects that are further away, no doubt due to the higher megapixel count.
5) I think most apps on iOS look better and are more functional, but the problem is, you have to launch an app to do anything in iOS.
I really wish Samsung (and maybe Google in general) could solve the idle battery drain. Losing 20% over 8 hours without even using the phone seems rather high when you factor in that you'll be losing that battery life whether you use the phone or not. Theoretically, this should mean that the iPhone would get better battery life with the same use, but I'm not finding that to be the case so far. I will probably be going back to my SG2 very soon.
Sorry for the long-winded post. Just wanted to collect my thoughts and present my personal findings.

U r right about battery consumption .
But i m sure Android is going to be so much improved and vast in features that we cant compare to any os in the world in future.
Biggest plus of Android is community like this and the freedom to change things inside it.

agree on most of the things u said there
but
when it comes to battery life i have no idea why its soo random with some people
i lose about 1% an hour on KE2
(stock was on the phone when i bought it no root )
but since i installed KF3
i lose about 2% an hour
rooted flashed from odin

I must have responded to 10+ questions on this forum in the last 24 hours as regards battery drain, i get 25+ hours on my GS2, if you search on here you will find many tips that will substantially increase your battery life.

check the new kernel ninephetamine. Have used the modified 1.4v (with deep sleep enabled).....promising results with undervolting.
Currently OC 1400, and undervolted.

Simple Answer
Iphone does not loose batter on idle cause it puts all apps to sleep state if not used for a while
Android phones in general are always using data for like your emails, facebook, etc if you have set the apps to connect say every hour or so
IF you leave WIFI on it takes up battery as well
I am quiet happy with my SGS2 ( 12 -15 hours ) heavy usage and I am used to daily charging. and its just the day time hours unlike people who may be posting their night time hours as well which add anything form 8-16 more

I'm not interested in disabling everything that makes Android what it is. If I have to modify it to the point that it's an iPhone, I might as well use an iPhone. I'm well aware of battery saving tips for Android. They almost always involve shutting down all automated services and anything that retrieves data. This is not a solution. I have some e-mail accounts on periodic pull and the most important ones on push. On the iPhone, I have all e-mail accounts on Push.
I also don't particularly want to use a custom ROM. I prefer to stay stock.
I'm not getting horrible battery life on my SG2. In fact, I get around 15 hours with the same kind of use as that on the iPhone 4. I would just like to be able to set the phone down for several hours and not lose a quarter of the battery.

i have tried every single battery optimisation and calibration tricks on my Android phones. My first Android phone was a htc hero, second SE X10 and Now Galaxy S2.
All the optimisation and stuff works if you sacrifice something on your phone. i like my display to be sharp and easy to see. I want my email notification to be prompt and so many other things.
I used to be Windows mobile user my last handset was Toshiba TG01. i never ever had any battery issue.
It is to do with Android system, it needs to improve. it has all the pace now and so many chances.
if this roumor is true then IOS will shrink sooner than 2015:

Why my Lamborghini needs more fuel than my Fiat Panda? I can't understand. Crappy Lamborghini, back on Panda.

Well if riding the Panda can get me through the jungle instead of half of it, why not?
Also, the Panda can get me more food via the App Store.
Granted though the Lamborghini has alot more fancy features and doesnt have mindless sheep following it
Anyway, coming from an SGS1, then an iPhone4, I heartily agree with the OP. Android is awesome but it's still rough around the edges. Sometimes the ease and boring simplicity of IOS is something that I miss, along with the Apps and definitely the games which Android is sorely lacking.
But then again I'd be reminded of steve and his itunes bloatware. ugh

Yes, but when Lamborghini is parked it should use the same as the Panda! (I.e. zero.)
Google really should minimise the stuff going on when the phone is idle. Google also needs to do something about all these rouge apps that always start up services that always run in the background. They should provide some way of limiting/stopping the CPU usage of apps running in the background.
Even the official XDA forum app still servers up adverts in the background eating up your battery (and bandwidth) if you press home instead of backup to exit.

wifi sharing is a bit of a bug that drains battery like crazy. If your not rooted thats definitely the screen off battery drain for sure. If there was a reason to root, just root to freeze that one rogue app.

But most of the stuff is pretty useless anyway all this Samsung bloatware is guaranteed to drain your battery, i don't see it as sacrifcying anything, ive got email on push and i still get over 25+ hours battery,i used an iPhone 4 for a few weeks and id be lucky to get 16 hours with medium to heavy usage.
My data is always enabled too, you can save a lot of battery if you use apps like Juice defender plus and system panel will also tell you which apps,etc are using up more than others.
At the end of the day smartphones are always going to use up much more battery than normal phones and this isn't going to change anytime soon until such time a revoultionary new battery is designed that lasts for days on end.
Until then people have to deal with it,follow the tips and you'll get good battery life, if you want absolutely everything "on at the same time" your simply not going to get it, not on the iPhone 4 or any phone.

Is my phone nomral? "Android OS" eats my battery

i have bought my GN last week, once i have got the phone, i immediately update it to KK1 (2.3.6, Hongkong version) via OTA.
i have read many posts on XDA that you guys with 2.3.6 are happy with the battery life, however, it is not the case on me.
as you can see, i have used for 5 hours after unplugging from full-charge, the battery drains from 100% to 65%, during this 5 hours, i had 10min phone call, took 2-3 pictures using build in camera, about 10 whatsapp messages
do you guys think it is reasonable?
what should i do to fix it?

These third party ROMs all seem to have one issue or another based on what I've read in the threads. Better to just root it and remove apps and tweak yourself.

I haven't had any trouble with Sheep Rom. I think the problem with some kernels is that the phone is not entering deep sleep. You could try installing setcpu and forcing it to 200Mhz while the screen is off.

Completely agree. Wish I never screwed mine up with Odin. Wish I could get back to my stock ron and just root, but my stock ron can't be found. I'm on the Hong Kong non modified ron now and am as close to being happy as I can get without selling and really buying.
I had problems with the sheep rom not showing apps in the market that worked and showed fine on the stock rom. Yeah yeah yeah, I know there was probably a fix but I'm not willing to spend all my time fixing silly **** that wouldn't be a problem.

I recommend starting with installing betterbatterystats to monitor wakelocks. That has identified my android os problems.

thanks guys for your suggestions on roms
i would prefer keep using the stock rom
will try to install betterbatterystats to monitor wakelocks, i will post the result after 1 day usage for our further investigation

Stock
I'm running stock for now, no root, and battery is pretty good. After installing juice defender ultimate, it's actually better than my GS2 battery.

rooted and using titanium to freeze a lot of the junk apps originally installed. Currently at 21 and 33 minutes with about 75% left. I never turn off wifi and have sync going all day. Browsing and a few voice calls. Not bad IMO

I would appreciate if you could you give us a list of those junk apps.

bunch to list (which I will do later) but go into running services. there should be a ton of crap (assuming your on stock) you can freeze. These are mostly stuff I would never use

Charged to 100% and left overnight...the drain was about 2% per hour...anyone can explain to me why..??...screenshots attached..

2% with wifi on is normal i think. just you off wifi then it will go < 1% /hr
You can use phone weaver to auto manage wifi. It will switch off at specific time and will switch on autometicaly at predefine time.
I manage to switch off data connection + wifi at 2am to 9am. and by bettery drain just 4% during this 7 hrs.

Hmm...but what about Android OS battery usage..its always high..??

wat is wrong with this, it showing you how much battery drained by OS. if your phone is workng then smthing shud use it na?
if your use is <1 %/hr, and that use, is with android OS mostly. it means not other than OS draining your battery.
Look to total battery draining/hr, and smthing (like ne service/application) over consuming battery, thn you have to worry for that..

And while using betterbatterystats...i saw in kernel wakelocks that vbus_present and deleted_wake_locks were on for a considerable amount of time...
Do they cause high android os use and drain battery..??

[HOWTO] Cleaning your ROM for better battery life ~ up to 5 days

Disclaimer
I am not responsible for any damage to your phone and/or any consequences from your phone being bricked, exploding in your face etc etc etc... You are expected to read the full description and use your brains to process this information, before even touching your phone. Assumed is that you know how to flash using CWM.
Whining that you disagree to remove bloat is not appreciated; If you want to keep your phone bloated for whatever reason, you are at the wrong thread. Feedback should be substantiated and reproducible, not a ventilation of your bottom.​
Context
The intention of this thread is to set an approach how to minimize the battery consumption when you are NOT using your device, e.g. when you are at work, sleeping, at some place that does not allow you to recharge, etc. This guide explains how to thoroughly remove stuff that you probably do not need, something that certainly will not affect your battery life in a negative way. The approach is based on the ROMCleaner script, which was extended a bit. Whether it is necessary to remove all the stuff as described, is debatable - nevertheless it is an approach that works for me, otherwise I would not be posting it.
Because a lot of people replied with phrases like "this is bullsh*t", let me state the following: This approach is in no way a guarantee that you will actually achieve battery life longer than 2 seconds after a full recharge. Neither is it a part of the bible, it is merely the approach I followed to prolong the battery life of my device - which I like to share with you. If you are still hating, wonder yourself: "What have I contributed lately?". In any case, at least try it out yourself before drawing your conclusion beforehand and polluting this thread.
The second discussion point is whether the battery should last longer than 1 day. According to many, you are not using your device properly if you would like this to be the case. My answer is simple: If you have no such desire, move along. If you do, like I do, this topic might be of some worth to you.
Furthermore, I honestly do not understand statements like '2-3-4-5 days is impossible' on one battery charge. If you are convinced that Jesus will return again, please do so, but give other people the space to actually find out whether it is the case for themselves.​
Some Introduction...
Have you been annoying your ass of because your battery is drained within a day, without even using the phone while at work? I certainly have. Coming from a SGS1, which used to serve me at least 3 days on one charge, I got instant diarrhea from the battery life of the stock SGS3 firmware.
Then I downloaded a ROM, stripped everything unneeded and more and finally got a battery life of approx 3 - 4 days. However, because I had ripped a ROM apart, which was a manual operation, updating became quite time-intensive. Therefore I also did not update, until the recent JB leaks. So this time I though: Lets make a script to do it for me, in order to make updates possible in an easy way. Then I only have to run the clean-script after an update.
After some testing, I am finally satisfied with my device again - Check out the screenshots. The results are achieved while having wifi constantly on, using google sync and whatsapp. The screenshots are based on Wanamlite XXDLI7; The first shows the battery usage during a night, the second during a day of light phone usage. I will post another screenshot when the battery is drained completely.​
What to expect and trade-offs
After completing this procedure you can expect significant increase of battery life when the phone is idle. If you are using the phone actively all day long, then this approach might not be of much worth to you. People who do not have time to play with the phone all day, e.g. because they work during the day, will probably find this most useful. The cleaning of your rom will remove about 70% of the apps/widgets that come by default, therefore it is wise to check whether you will not lose apps/widgets that are valuable to you. You are still free to modify the "script" according to your need/desire.​
So what do we need?
A DEODEXED Stock-based ROM, I prefer wanamlite http://forum.xda-developers.com/showthread.php?t=1705866
ROMCleaner - http://forum.xda-developers.com/showthread.php?t=1827817
The attached ROMCleaner_user.txt will sustain default samsung browser, calendar, email and messaging. (untested)
The attached ROMCleaner_user_jb-apps.txt expects you to replace the JellyBean apps discussed next. Beware that the stock browser, calendar and email are not tested by me and could drain your battery faster.
Because I had some issues that ROMCleaner would not read the ROMCleaner_user.txt, I had to integrate the file into the ROMCleaner package. To do this, you can download the ROMCleaner package and replace META-INF\com\google\android\romcleaner\ROMCleaner.txt in the zip by the file you just downloaded.
Packages to restore some stuff ^^
If you have chosen for the JellyBean apps package (jbapps-avdaga.zip) you will get:
JellyBean browser + calendar ripped from http://forum.xda-developers.com/showthread.php?t=1797109
Inverted JellyBean apps: email and messaging ripped from http://forum.xda-developers.com/showthread.php?t=1780559
In case you want Samsung Apps store for free fancy games, get it from http://forum.xda-developers.com/showthread.php?t=1861409
Got the packages, whats next?
Put all files on your phone, reboot to CWM.
Make a backup of your current system, smart monkey.
Flash the JellyBean ROM of your prefrence if you have not already. (If you come from ICS, wiping your data guarantees best results).
"Flash" the ROMCleaner script, either by using ROMCleaner_user.txt approach, or integrating the file.
If necessary, flash the provided JellyBeans apps package and Samsung Apps package.
Reboot and enjoy your awesome battery.
Thanks to
Wanam for his awesome ROM.
Patrics83 and others for ROMCleaner.
Temasek and CyanogenMod team for proper Android apps.
All others I forgot.

@OP: Your post is missleading. Removed bloatware has nothing to do with the battery life.
After intensive research I came to the conclusion that there are only 2 major issues for the battery drain on vanilla stock ROM (JB DLI8).
Those are:
1) Samsung push service : SOLUTION -> simply unstall it, bacause you don't need it anyway (e.g. via Titanium backup).
2) Wrong fast dormancy setting : SOLUTION -> use https://play.google.com/store/apps/details?id=com.gokhanmoral.fastdormancytoggle.i9300&hl=sl from gokhanmoral to toggle it to the setting supported by your carier. BE careful not to toggly it exactly the oposite.
With these 2 mods on stock DLI8 I get less than 0.5% battery drain while idle over an hour.(Mail sync set to every 30 mins)

Nice!
I've been on Stock-rooted since I got the device. I'm definitely going to try this out.
I use my phone plenty, doubt I'd be able to get 5 days out of it, but we'll see.

Is it better than just freezing all the unwanted apps?

Cannot promise that, but you can compare the list of removed apps in ROMCleaner.txt

Will it work with a LH1 (BTU)- stock rom? (Rooted, of course)
Thanks!

According to the images, the screen was off 99% of the time, am I missing something?

It should, make a backup and try for yourself. Do take into consideration that you might need the default ICS apps or simply use the ROMCleaner_user.txt, not the JB one.

The first image is supposed to show how it performs when idle, the second is after a day of usage. Primarily used it for some messaging and calls though, however the main point is that the battery is not drained when not using the phone. When I used a stock rom the battery was depleted for 50% after half a day without me even touching the device :-\
Of course if you use the phone normally the battery will be depleted in 3-4 days, like i mentioned in the intro.

I know how to get years of battery life, charge your phone to 100%, take the battery out for at least 2 years, and it should have some life left in it, you must make sure you don't put the battery in for at least 2 years.

What are you guys whining about..if it can improve your battery life and remove the apps that you dont need, why not? You should be thankfull that people put their work in such things in their free time.

Yay, let's remove a bunch of features from the phone so that when you're not using it at all, you can get 5 days of battery life! :silly: Your claim of "normal" usage equaling 3-4 days is pretty unrealistic. Battery usage is subjective with thousands of variables, which makes lofty claims of battery life completely pointless.
Nearly all of your battery life improvements are just doing step #1.
You're using a rooted and tweaked stock ROM with a tweaked kernel. Just by doing this, you're going to get much better battery life versus stock ROM. Nothing new to see here. Removing what little other "bloat" that Wanam left in the ROM by removing a bunch of apk's (that don't run anyway unless you launch them) and replacing a few ICS apps with JB versions will only offer a very small improvement.

Please install any stock-based ROM and check the services that are running in the background - without you even know you had them. There is a lot of garbage coming in all stock-based roms, and I really do not understand the problem of removing stuff you do not use; Morever, I think this is something people should do in all apsects of life; that is removing sh*t you do not use.
I conclude your assertions are based on thin air, as you did not even take the time to test this approach. I have spent quite some time testing stuff out and posting my observations here - so please do not post if you have nothing constructive or reproducible to say.
Last thing: I do not replace ICS apps with JB, this stuff was tested on a JB rom - but you knew already because you read the full post

so basically you debloat a stock deodexed Rom? Any other changes I'm missing?

Besides changing some samsung apps for CM10 ones, that is it indeed. Though the debloating is more thorough than proposed by others.

Ok, thanks,, just wanted to know exactly what the script did, prefer my own debloating and tweaking, but good for newcomers.

there are also people that are not normal and want to use their phones on trips or in situations when they have no charging opportunities

Does this work on the omega rom by any chance. i only need at least a full day worth or battery

It should work on any stock-based rom, also omega.

My thoughts...really.
I don't wanna sound rude, yet i had to agree with some when they say "buy a Nokia (old one of course" or just "disconnet for one or two years".
It's virtually impossible with the kind of gadgets we have these days any battery last more than 1 day.
I've made my own mods and roms from scratch in recent past for X10, so u may consider at least that i known what i'm talking about.
The only way, no mather witch brand you like or believe its the best, is by f#@king your screen. Period. That is the main reason why every phone just last 1 day with "normal" use.
If you've payed attention i've used "normal" expression witch means phone, mail, sync and didn't wrote "heavy use" that will include music, YouTube, videos, etc.
Like i said. I've made my own work in the past and still do some minor (?) changes and i must say this: i'm glad if my phone last one working day from 7AM till 23PM. Yes! Working day, that's why i dont't develop anything.
If you or anyone else state that your/his phone had better battery life than this i make two considerations:
1. You're (not you in particular) a liar, or;
2. You simply don't use your phone as you can.
If you dont consider that you belong at the first consideration than..."buy a Nokia..."
Another thought:
You just bought this (or similar) phone for a status matter or money it's something that's really cheap for you (another 2nd choice).
Like i said...just my 2 cents.

[Q] Battery life is turrible

So, I got a Galaxy S4 back at the beginning of December, and the battery life has just been awful since I got it. I'm talking 5 hours max.. of juice. Its bugging me because I have tried so many different options and nothing makes it last any longer. One time I got 8 hours and I was like planning on throwing a parade because it was so groundbreaking for my GS4.
Here's what I normally have going on:
Admittedly I use my phone quite a bit and it's always on full brightness because hey its a $600 1080p phone so I want to be able to use it to its full potential.
I do not have one game installed. Never been a huge fan of mobile gaming.
I usually have a 4-5 bar 4G signal and barely use my wifi because it's like 300kb/s down.. And really spotty.
I may listen to 30 minutes of music a day.
Most of the time I'm on twitter and looking up stuff on Chrome.
This is not a battery issue I do not believe because my brother got the same phone and he has had similar issues. My brother uses his phone maybe half the time I do, so I doubt it is my usage that is bringing it down. I seriously do not want to have to contact Samsung for them to tell me it probably has water damage and then ask me to wait 2 weeks to get my phone back. My phone does tend to get warm from time to time but I've seen multiple reports of that. My iPhone 4 that I upgraded got 8 or 9 hours of battery life on similar use. (Android rocks)
So what is the problem?
P. S. my phone ran down 8% while typing this.

Are you running a custom or stock rom? And are you rooted?

Look at your battery usage in settings. Screen should be number 1. What's after that? Get betterbatterystats and see where your wake locks are. Without some additional info it's hard to help you

It depends on what I am using the most. Most of the time its below 10% of total battery use. I would say it is mostly Chrome at 4-8%.
Right now it has been on for 37 minutes and is at 85% battery.
84% screen
7% Chrome

so under battery usage it's just screen and chrome usually ? (iId dump chrome to begin with anyway)
Is GPS on ? Any other apps that would be constantly syncing like facebook, twitter, etc ?

Yes, normally screen and chrome are the biggest consumers but I do use a few more apps. I've been wanting a Chrome alternative, but nothing I've tried has been as efficient.
I do use Twitter and Facebook(rarely), but at the same time, my brother doesn't use any social media and his battery isn't much better.

The biggest user of battery would be the screen, LTE, and GPS or location based processes. Honestly LTE that doesn't use much unless you are streaming all the time. Something isn't letting you phone go to sleep and if you can root I would just do it to be able to use an app like greenify or another wakelock killer that lets you keep apps from keeping you phone awake. Also turning off sync in general helps i.e making you refresh stuff manually.

Thanks for your help so by the way. I always have gps off and I only get regular 4G in my area. I will check with Facebook and try to turn off automatic syncing. Rooting is an option, last time I went through kingo and did it just fine until I tried to flash Cm over my locked bootloader *facepalm* Haha. I haven't heard anything definitive on the downside of using that tool. It was very simple. Would you suggest me going that route for Greenway?

No problem just hit the thank button
I'd root and just leave it stock the rest of the way. With battery life it's always YMMV. The battery stats given in the setting menu don't tell you much so apps like wakelock detector or Greenify allow you to stop apps from "waking" the device all the time to either push notifications, sysnc, do whatever crap they do in the background. You could also get something called better battery stats, the app in on xda just google it, and let it run from full charge to dead and then take some screenshots of partial wake locks, how often CPU is in deep sleep etc and others can help sort some out.
Just root with Kingo as its easy and leave the custom rom's alone haha.
BTW how did you fix the brick form flashing a custom rom on MK2 ? I'm on the good MDL firmware so not sure how others fixed the MK2 brick

Well after about a zillion tries on Google I finally found where someone got out of soft brick. It was something like hold down volume down, home, and power buttons until two options come up after you first power on the device. They are like "proceed to recovery mode" or "boot regularly" (something close to those anyways) and then you hit the volume down key to select boot regular and it boots up the phone without seeing that Oden screen. I was so relieved, I had already BSed my chat with a Samsung rep so they probably would have fixed it do to "accidental" downloads caused my phone to brick.

Watch out having your brightness to 100%. My statusbar got burnt into my phone. Just be careful. I can see the clock numbers(blurry) as well as battery and such. It sucks.
