I'm a truck driver and I'm a heavy user.
I did too before I made the changes below. These all work with the Stock Rom.
1. Installed No Lock (so that I don't have to swipe the screen to unlock, just push the power button)
2. Set screen to turn off in 30 seconds.
3. Installed Brightness Widget (allows changing the brightness from the home screen
4. Installed Screen Filter (lets me really darken my screen at night.
Try those and see how you do.
5. I then flashed the Infused Rom (I now get up to 10-14 hours)

Also, Turn off GPS and Wifi when you're not using them.

Battery
After much experimenting and monitoring of battery use I find that the biggest drain is the screen display, so go to settings-->display-->brightness and lower the screen brightness as low as you comfortably can. Also when you you are not using the phone make sure the screen is off, I have trained myself to automatically hit the power button every time I put down the phone. If you listen to music through your phone make sure the settings on your music players allow the phone to play when the screen is off and turn the screen off while it plays.
GPS also drains the battery, so I keep it turned off when I don't use the Nav. When I use the Nav I know the battery will drain at a rapid pace, nothing you can do there, even if I have the phone plugged in to car power while using Nav it still drains the battery! Drains slower than unplugged navigating but still drains.
If your watching videos then your S.O.L. there's really nothing you can do that will increase battery life enough to make a difference during video playback.
I get 10-12 hours with regular use and stock rom. Worst was 8 hours best was 24.

Thanks for all the advice this has really helped my battery

3. Installed Brightness Widget (allows changing the brightness from the home screen
There was a recent post that showed a shortcut for changing the screen brightness from the homescreen without any additional software. First, turn off auto brightness. Second, tap and hold the menu bar at the top. Third, slide left to reduce the screen brightness and right to increase screen brightness.

How does it drain your battery when its plugged into the car? I have never seen that on any cell phone. That my friend is messed up if true.

It seems that Samsung ****ed up and included phone CPU/screen/etc usage when measuring battery charge current.
This means that the 600 mA stock battery charge current limit isn't just going to the battery, it's split between battery/screen/CPU. If screen/CPU/etc go above 600 mA (Navigation at full brightness seems to be the most common way), battery starts draining.
It also means that unless there's something I'm missing (which I could be since the MAX8998 datasheet is super-ultra-secret), our phone isn't going to be able to do proper charge termination - if the screen is on/CPU is running, it will cause a falsely high battery charge current reading, which will cause charging to fail to terminate.

Juice defender
I found that juice defender helped my battery and i just use the free version it's a great app

I used Iphone 3g 3gs 4. None of them drain battery like this one. First time use Android phone and getting a bit disappointed of this phone. It's draining 2% every 5 mins and im using stock Rom.

Install a ROM. Infused v2 nearly doubled my screen-on battery life and tripled my screen-off battery life.

look in about phone battery use to identify the biggest battery user, it should be the screen. anything else and there is a problem.
the cell standby may go high on froyo rom, turning on flight mode and turning it off will correct that, it's an android bug.
on gingerbread the android os or android system may hog battery occasionally. some think it is the wifi sleep policy but it pops up on me without setting the sleep policy. the fix for that is to pull the battery for a couple minutes and put it back in and restart the phone.
next manage the screen brightness
install a custom rom, there are issues with certain firmware keeping sensors active wen they shouldn't be.
turn off unneeded sync options (i find that auto fetching my email uses a lot especially with my gmail already set to sync),
use wifi when you use the internet if possible, turn it off when out and about.
monitor cpu useage of apps that are cached in the task manager
kill apps that use cpu
if needed turn the max cpu clock down to 800mhz
set "use wireless networks" for location when possible for general location (limited to city level at times)

Actually, high cell standby is OK if the phone is screen-off often.
Cell standby is always my top user - but my phone is sitting on my desk with the screen off frequently, in a location with weak signal. Weak signal makes cell standby usage go WAY up.

Syncwifi application is awesome for extending sync settings to gain more battery

JuiceDefender!!
I agree JuiceDefender works!! I had to charge in the middle of the day. Now with moderate use it will last all day Im on stock Rom.

I easily get 2 days out of my Infuse, no idea how some of you are managing to only get 8 hours. After rooting my phone and freezing the bloat i easily get twice the battery life of my prior iPhone 3GS.

Green Power vs JuiceDefender

Hello everyone!
I was just wondering between these two apps...
Which one works better for you and if will be great if you can share your configuration!!
Also, does anyone knows is any of these two disable whatsapp and gmail notifications?
Many thanks for sharing!
Cheers!

IMHO
I can answer about Green Power Premium:
It doesn't have such option like disable notifications. He does such thing like disables data connection for amount of time you chose (for me it is 15min) and then enables data connection for amount of time you choose (for me it is 2min)
Now my Galaxy Note works 2 times longer (from 10h to 20h)

WOW! double time!!
thanks for sharing!

I have been trying both, and while both of them seem to deliver a noticeable reduction in power draw (actually in my case a dramatic reduction), of the two I'd have to give my vote to GreenPower (I'm using the full version). The power reduction is at least as good as Juice Defender Ultimate, and the premium version is significantly cheaper.
Both work by turning various features (mainly Wi-fi/3g/BlueTooth) on and off automatically, but as result can cause delays in things like receiving push-mail and that kind of thing. With Juice-Defender I found this to be quite noticeable, but I'd have to say that with Green-Power I haven't really noticed it slowing down messaging or anything else.......

I've used them both - and deleted them both. I'd rather manage power myself.

i am using 2x Battery for me this is the best. simple and clean.

I usually use JuiceDefender but decided to try out Green Power. I really like it but I have a hard time getting my phone to sleep properly on GP.

i use widgetsoid and just enable my connection when i want it (wifi/3g)
i could never find the proper app that did exactly what i wanted- rather just have control.
going that was and using the phone an average amount my battery goes from 100 -> 75 from the time i wake up (7am) to the time i got to bed (12-1 am)
the 2500mah battery is pretty good!

With JuiceDefender I can get my phone to sleep 95%+ of the time but with GreenPower, my cpu is only sleep 40%+. Can anyone give me tips to get my cpu to sleep more to preserve battery?

Just out of interest, what happens when you browse the web and GreenPower has turned off the Data Connection?
Or you're watching a youtube video and it decides its time to turn off data?

Tried both versions and found green power premium to work better for me. (Price was a good point too.)
However the next day I found that if I left my phone for a while (Around 1 1/2 to 2 hours), the display would not turn on and If I called the phone it would not ring. Only way to fix this was to press the power button for 10 seconds to reset the phone.
Uninstalled green power to see if this was the cause and hasn't happened since.
Was wondering if something similar has happened to other people?

I had to go back to JuiceDefender since I couldn't get my phone to go into deep sleep with GreenPower.

Hi, i went for Green Power. I found it simpler to configure, more focused on the job. Juice Defender has to much possible settings and complexity, this makes it a great tool but might also lead to poor efficiency.

I have never used green power before but im on juice defender. I have experienced auto turn off by the note due to a set cpu settings that govern lower clock to cpu at a certain condition. Due to the big display on note i think lower cpu clock wont do it. Because of that the device turned off itself. Upon failure to operate. Hope this solves your problem

I have tried JuiceDefender but ultimately prefer to do everything manually. Some how I always feel the auto manage apps will have everything off precisely when you need it. I use the SwitchPro widget to quickly enable/disable the various radios from my home screen and it works great.

@ Aldragor
I have/had the same problem. In the beginning I thought that my launcher would be the cause for this problem, but after I disabled my Green Power Premium it hasn't happend since now.

Juice defender ultimate, the feature of switching 2g 3g on stock ROM alone was worth the price!

After figuring out how to config GreenPower properly, I went back to it.

I used JuiceDefender and thought it was great.... when it worked. However, I used it mostly as a scheduler with about 15% battery saving which I took as the icing on the cake.
I want all connections on during the day (peak) so I can take skype calls, etc.. When I'm home, I just want to periodically check for mails, etc (so have connection enable every 15min) and when I go to bed I don't want to be disturbed by emails, messages, etc but still want phone/sms on in case there is an emergency. And most of all, I didn't want to have to manually do that every day.
Problem was that it never really stuck to the schedules. This was the ultimate version but it was a crack as they never offered the ultimate on a trial. I wanted to evaluate the ultimate and buy if it did the job. So, it might have been a bad crack which caused the problem, but I guess I'll never know as I don't want to risk wasting the money if the schedule problem persists.

I am a lover of juice, it keeps he juice in and right

here's to the people who think there battery is bad

1) there r chances u might have a faulty unit but the biggest thing that drains ones battery is cell signal strength a couple days back. I couldn't understand how I was getting terrible battery on wifi in my house I realized it was cause in my house I only have some bar
Share some other reasons why battery might suck for some
Sent from my HTC One X using XDA

1) Sticking with the Sense launcher
2) Widgets, widgets everywhere (it takes CPU cycles to keep those pretty widgets drawn on the screen
3) multiple home pages (read: more than 3-4)
4) leaving your wifi on when not connected/trying to connect. Your wifi, if on, is constantly looking for signal. Turn it off when you leave the area.
5) Sync. I have 6 gmail accounts I sync to. I turn them all off while at work. They can wait.
6) Update frequency of apps (facebook, weather, dropbox, google+, etc) Also, auto upload of pictures. Change the settings to either "only over wifi" or "while charging only"
7)Auto-brightness. It takes juice to have that little sensor constantly monitoring the light conditions. Set it to manual and change as you see fit.
8) Seriously, delete most if not all of the sense widgets. Check the update frequency. Run another launcher.
9) Some web browsers (chrome) give the option to pre-fetch data. Stop that
10) Stop being a SAP and checking your phone (while in public) every 5 minutes. No one has sent you a message and you already know the time. The screen on is the biggest power drain.
SAP: Socially awkward penguin
edit for clarification
1) sense is a hog. As "light" as some websites may paint it, it is still the bane of HTC's phone battery issues. There is no way to turn it off but you can keep it as a background process if you use a different lighter launcher (nova, apex, etc...)
2) Widgets require updating (internet) and need to be redrawn (cpu) both of which drain the battery
3) the more pages you have, the more cpu cycles it requires; see #2
4) self explanatory
5) see #4 (Seriously, do you need to have all your email all the time?) I mainly only receive updates to sites I visit (XDA, and deal-a-day sites) so I can deal without them while I'm AFC (away from charger)
6) The more you update, the more it needs internet access the more it drains the battery
7) self explanatory
8) If you insist on using Sense...You're gonna have a bad time
9) self explanatory
10) How often do you pull out your phone to "just check the time" and how many times do you actually read the time? I'm a victim of this, too. Pull out phone, power on, look at screen, check for notifications, turn off phone. "****, what time was it?" Rinse, repeat.
Under battery stats, screen is always, always, the biggest culprit. Minimize this by not turning the screen on!! Wear a watch, maybe even a bluetooth watch (to check for alerts) and consciously avoid pulling it out.

A sap is a gullible person; a dupe.
I have been seeing SAP and always thought that's what it meant, but now that you say it, it makes more sense as S.A.P.
Thanks! lol

Or if you're one the peps that loose 1% battery for every minute of screen on time. Like me. Replacing tomorrow hopefully.

I'm losing crazy amounts of battery when talking on the phone. A 3 minute call will take 10-12% of the battery. Usually after 20 minutes talk time I'm down to less than 50% battery. I've turned everything off, notifications, syncs, and most apps. I'll see how it does but I may try returning it for another.

I'm seeing this problem too. 15 minute phone call shows as 14% of my battery life when i'm down to 10%. I think I might need to take mine back too.

Juice Defender of any use?

Is there any practical reason to install these battery-saving apps? Most of them I have seen just tweak the menu options of your phone you can already access manually and give no additional functionality to the phone itself that you couldn't already do.
Is this any different? Or will it just sit in the background consuming battery life itself just to run its "function"?

I've always had horrible time with these "battery saver" apps
Just let android do its thing
Turn brightness down, turn off GPS, BT and 4G/LTE when not in use and lower the intervals of background updates (and by that i mean turn the time up higher lol) on apps and your battery should last longer

I used Juice Defender for awhile and realized it wasn't what I wanted. I tried Easy Battery Saver and that really helped out a lot.
What it did was to disable all internet, GPS etc when not in use or screen locked. It really helped out a lot in helping to save battery

I don't find they help much anyway and will just drain your battery faster, I think they're kinda designed for the average user who keeps everything on and don't know how to do all the things alot of us who are more better with Android already do.

All I had is bad experience with battery savers and they drain alot more then they save for me plus I already turned off all online stuff like Wifi, bt, 3G, mobile data etc.

Juice defender pro is doing a great job for me. Recommended! No joke at all.
Also it has come to my attention that it has a feature of learning. The more time you have it in your phone then it will do a better job to save you battery. Also alot of settings to do depending on how much juice you want to save.

On my phone, I used to run Juice Defender all the time. After awhile, I realized all it was doing was turning 3G off when my screen was off and turning it back on when the phone woke up. Since I wasn't necessarily using 3G every time I woke up my phone, I got into the habit of just turning 3G off and on only when I need it and stay on Wi-Fi as much as possible. After uninstalling Juice Defender and growing accustomed to found this, my battery life has improved at least 3x and I have never looked back. Just my 2¢.

Yep, I also stopped using JD a long time ago. There are much better ways of saving battery than adding one more application - if you know what you're doing. Using JD is less work, but it's not the best way.

If you are toggling wifi, data, gps etc by your self you dont need JD. I used it sometime but I have habit to control all toggles myself and just found JD interfering with my choice and it shows it saves some 1.8X battery but I didnt find it that much.

I have tried many of them; in my use/ my phone (Nexus S, unrooted, stock JB) is Battery Stretch far the best, really almost doubling battery life.. JD, etc did save some juice, but far less, than Battery stretch. Just my 2c.

Personally I'd call my level of use on Android to be near expert. Not really a developer here, but I'm a very proficient user.
I'd say Juice Defender is totally full of crap.
So what can it do? It turns off "3G?" I swear this misnomer came from the US or something. We somehow equate 3G with data. I thought it meant it would throttle me back to 2G while the screen was off, but all it does is turn data off. Now here's a question: What the hell is the point of a smartphone with its data off? If you like social networking, email, communication, you WANT those notifications to come through. So what does turning data off while your screen do? You might as well turn off data manually and then turn it back on when your screen is on.
Furthermore, if you're interested in saving battery, use wifi in places where data sucks. The minute you turn wifi on, data is switched off. You don't need Juice Defender to figure this one out.
I can see 2G/3G auto toggle being useful, but this can be installed separately as the 2G/3G toggle app for CyanogenMod.
You should be able to tweak your battery to max it out without the use of any 3rd party apps or rooting or anything like that. Tons of newbies install a bunch of apps and as a result here's what could be draining for example:
- Google+ instant upload
- Dropbox instant upload (wow way to duplicate Google+ and effectively double your data use and battery consumption)
- Pulse news sync
- Google currents sync
- Gtalk 24/7 push
- Google latitude
People always say turn off GPS but I ask why? Are you leaving your maps on for 10 minutes at a time? I use location services a few seconds at a time. Show up to work? Checkin at foursquare. Walk into a bar? Checkin to foursquare. About to go home? Take a look at Google Maps. All that takes 1-2 minutes tops. How much battery should that even consume? 1%? Turning off GPS means what? I consume 0.5%? Woohoo. BIG SAVINGS there bro. Furthermore you gotta remember to turn it back on if you ever want to use navigation, and if anything having GPS accuracy helps when using location services like for Foursquare of Facebook checkins. You could find that venue as one nearby rather than scrolling around trying to find it because the cell tower puts you a mile away. You save time like that too.
Screen is the big one. Autobrightness should work well on most stock ROMs and even most stable ROMs. IF you're using your phone outdoors expect that screen to drain like mad, but indoors it should be fine.
Honestly, JuiceDefender accomplishes its task by crippling your smartphone. That's not what a smartphone was built for. You should be able to use all its features and get through a day unless you're on your phone 5 hours straight surfing. Then expect it to die soon. No juicedefender will save you there.

I think the point of JD is that you don't need 3g data on all the time, you can set it to enable 3g data every min/5 mins/30 mins/hour etc for a set time, if background processes are sycn'ing (gmail, facebook, twitter etc) it will wait until the sync is done, this means its up to you when you sync data, I sync evey 15 mins and it works really well. When you switch the screen on, data is automatically enabled, i have set it to use wifi when in range, or 3g when out of range (again its automatic) JD does save you battery and it does it all on its own, millions of downloads can't be wrong
Sent via TCP/IP

And that's exactly what Battery stretch does - with a much smaller footprint/memory/battery load than JD!
Just give it a try - I have tried all of them- and judge it for yourself

Another one to check out is 3GBattery, very basic but maybe that was the point too

Juice Defender is a fickle mistress. It does what you want, but it can get in the way. I use it when I know I'm going to be away from power most of the day and I either forgot my Sparq or it won't be practical. When properly configured Juice Defender bloody works. I usually end the day with a 2.4x boost when I use it. Normally my phone needs a pick-me-up after about 8-9 hours. With Juice Defender I had 35% left after an 18 hour day. The only difference was Juice Defender and using Screen Filter to drop the brightness. Had about 3.5 hours of screen on time.
Juice Defender's bread and butter is its data toggle tool, and there are some things to keep in mind with it to make the most of it.
When the data state on the phone goes from not connected to connected programs that can sync want to sync. This adds a lot of data use and cpu cycles. Because of this I've used the Application Specific control rather than having data toggle on at screen on/unlock. I don't want data coming on because I reply to a text. Data comes on when I call up an app that needs it, and data runs in the background for Music and Spotify only.
There's the argument of crippling a smartphone, but honestly, 99% of communications that come over the data network aren't urgent. Urgent communications are calls or texts. No power is more crippling to a smartphone than no data.

It's an absolutely fantastic app, but the memory footprint is huge! Even really fast devices like my evo lte slow down a little over time

[Q] Do the screen power saving options on this phone make a real difference?

The settings on the S3 have the following power saving options available: Auto adjust screen tone, Screen Power Saving and background color. Do any of these settings have a decent or better impact on battery life? I have a hyperion 4200 battery and use Lux autobrightness to lower screen brightness below zero when I dont need a bright screen, and seem to have my phone currently doing okay when it comes to wake locks, so wondering if these options make any noticeable difference in battery life or are they more gimmicky like a lot of the other settings choices.

I think the data syncs are more of a culprit than auto brightness settings but then again I have auto brightness on and it still helps. I notice my wife's phone gets better battery life than mine because she doesn't have as much data syncs in the background as I do even though she is constantly playing word games. She doesn't use FB, Twitter, Google plus, Google Music or Dropbox and I do. We both charge our phones at night but she has more screen time than I usually, stock batteries too.

I consider my battery life to be okay. I use my phone a lot so I cant expect the multiday cycles people have. I wanted to know this more for information. I have all my auto syncs off except for youmail, which i need on to update my custom voicemail greetings. To sync everything, i wrote a tasker action to sync everything everytimebi connect to a wifi access point other than gmail. For gmail, i have it set to sync every other time the screen turns on. I am able to do this because of the synker app from play store.

I'd say power save works. Extra hour maybe.
I turn off WiFi and data when I don't use it and my phone last all day with heavy texting and frequent WiFi use.
