1.Reduce display brightness of your screen
Although Samsung Galaxy S come with Super AMOLED which is supposedly to reduce your battery consumption but ironically it is one of the biggest battery life eater of your phone. Try to disable Automatic brightness and set it to the lowest level will improve your battery life a lot.
2. Remove unused widget in the menu
You must always remember that the more widget you have, the more battery life will be consumed up especially those widgets that use data connection and auto sync based on schedule. PS: only keep those widgets that you really need.
3.4. Turn off Bluetooth, GPS when idle
Only turn on Bluetooth and GPS when you need it, otherwise please disable it as it will consume your battery resources. Or please ensure that the charger is hook on your device when you turn on the GPS in the car.
5. Turn off 3G data connection, use Wi-Fi instead
Always gets connected with Wi-Fi when available. 3G data connection consume more battery compare to Wi-Fi connection. Turn off both of them when not needed.
6. Ensure you phone have a good signal as poor signal consume more battery life
When the phone is at the poor receiving end it will tend to use more power than usual to increase its signal strength with the communication tower. So it is always good to make sure that your phone has a good signal reception. You can try to switch to 2G if 3G connection signal in your area is poor.
7. Try to disable / reduce auto-sync whenever possible
All you have learned, data connection does consume lot of your battery life. By disabling the background scheduled auto-sync applications like Facebook, Gmail and Twitter can save your phone lot deal of battery life. If you really have to turn on the auto-sync feature in the phone try to reduce the frequency of auto-sync will also help to improve your phone battery life.
8. Disable new Samsung Apps notification
You can turn off new Samsung Apps notification if you not using it.
The configuration can be access through ~ >Settings >Application > Samsung Apps > Off
9. Turn off motion sensor
Only enable the Samsung Galaxy S Motion features that you using and try to disable those you not using like turn over, tilt, panning and double tap, turn them off as it might save your some battery life.
10. Use solid black static wallpaper and no live wallpaper
Most of the phone including Samsung Galaxy S Super AMOLED will tend to use less power on just solid black wallpaper than a lively solid white color based wallpaper because there will be almost no backlight on the screen. Please do bear in mind that a lovely animation live wallpaper will even cost you more battery life as ~ CPU power = battery life.
11. Fully close application that not use
Samsung Galaxy S is a super multitasking mini computer that come with dual-core processor but running a lot of applications at the background can actually increase your battery usage because they all require your phone CPU processing power. So it is advisable to fully close all the background applications that you not needed.
12. Freeze unused bundle applications
Too many original bundle software running in your Samsung Galaxy S? Freeze them… Titanium Backup Pro provide a way for you to freeze away all the stock application like Social Hub, Email, Maps that are running and utilizing your phone processing power even when you’r not using them. Ps: Your phone need to be rooted before you can use the Titanium Backup Pro.
13. Undervolt and underclock You 800Mhz GHz CPU
Aside from display, Samsung Galaxy S′s powerful CPU is one of the reason why your battery life eat up so fast. You can just underclock and undervolt it with SetCPU if you don’t need that much of processing power. Ps: Your phone need to be rooted before you can use the SetCPU.
14.Download and install JuiceDefender
With an amazingly over 5,000,000 downloads recorded so far in the Android market, JuiceDefender will definately extend your the battery life of your Samsung Galaxy S. JuiceDefender pack with powerful and easy to use power manager app that specifically designed to extend the battery life of your Android device. It can automatically and transparently manages the utilisation of your S battery like when to enable and disable the 3G/4G connectivity and WiFi.
JuiceDefender is available in the Android Market for free and if you would like to have a more powerful (customisable) version you can download the add-on JuiceDefender Ultimate for a small fee of $6.83.
15. Use custom ROM / firmware
Custom ROM / firmware offer a lot of optimization and tweaks to improve the performance of your battery life. You can try it out if you feel that after you have tried out all the tips above and your battery still draining too fast. But please be reminded that flashing a custom ROM / firmware will be voiding the warranty provided by Samsung.
Please let me know if there are other tips and tweaks to improve battery life of Samsung Galaxy S/Cappy that I have missed out.
I think #14 is not necessary if you are running a custom ROM
why wouldnt it be?
I believe number 11 has been proven untrue in the fact that killing tasks that the phone will reopen soon after actually reduces battery life hence the reason task killers are bad. Also the captivate only has a single core processor.
Other than that nice work it should help people out.
If you use a stock ROM with no voodoo color built into the kernel, then use full brightness, I do and I get great battery life, the screen isn't the biggest battery life sucker.... this isn't the greatest battery saving thread from what I can see.
Sent from my SGH-I897 using xda premium
Generally good tips, but definitely a few holes here and there.
For example, GPS doesn't drain when 'on', only when certain apps use it, making it pretty safe to keep toggled on all the time.
You can go further with SetCPU and other similar apps but underclocking during screen off, and I think that's helping me save battery in my personal experience.
Having a black wallpaper is good and all, but I feel that doing that is a bit too far in optimizing battery life. What's the point of having a pretty decent screen when all you do is use a black wallpaper?
Or flash Darky rom 10.2 Extreme Edition.

That is no good, considering the screen should be taking most of the power.
You either arent using your phone or you are crushing batteries in hours.
No I'm using it, Android OS process in ICS includes more than what they do in GB. It last all day (~15 hours with %40 left)
Sent from my SGH-I897 using xda premium
Yeah I have the ICS port, build three, and the battery sucked the first day due to all the downloading and cpu usage, but after that and a full charge and battery diagnostic wipe it was a great life with decent usage on apps and data and messaging with auto brightness
In Point 11, Captivate uses single processor....and killing system apps causes more battery drains....
My limited experience with roms suggests that as roms are works-in-progress their battery life can vary widely. Serenity6.1 has really seemed to be a long life rom.
These steps do make a big difference, also the Beta 2 build for ICS solves a lot of issues that users had with ICS battery life. Honestly if you want even more battery life grab the 3500 mah extended battery off amazon for $10.

Basically dont use your smartphone as a smartphone. Thats what you're saying by turning off all the good features of the phone.
1, 3, 4, 11 are like NO DUH!!!
5. Are you saying use EDGE? It will save some battery, but you have to consider it may take longer to load something, and thus the screen might be on longer, negating savings. Plus, it's a PITA to change back and forth.
6. Other than switching to EDGE, not really in your control.
7. That's stupid. It defeats the whole purpose of having a smartphone.
9. As long as you lock orientation. I doubt it saves much though...
15. YES, that can be HUGE.

I agree. I think a compromise is a better idea. A lot of ROMs have black wallpapers with a small % of extremely brightly colored random or geometric designs, or green android-ish swirls or something that look AMAZING on the AMOLED screen.

Idk if this goes in Q/A or not I never had a Q/A section as I came from the amaze but anyway. What battery savers do you guys find best? I Use Batter Defender but doesn't seem to really extend it. Would i be better of not using one at all?
I use 3 programs to help me maximize my battery life.
1) Badass Battery Monitor to figure out what's sucking juice, how long I've left, and how long until I'm full.
2) 2x Battery to manage background data. This probably saves me the most battery by disabling that data transfer a lot of the time.
3) Lux Auto Brightness to tweak my screen brightness. It's pretty much on "dark" now all the time aside for when I'm in really bright light.

I use the free version and it's very good!
I think the most effective battery saver is to flash a kernel that has become voltage control features and undervolt the cpu.

I'm not a fan of under volting the CPU. Mainly because if my understanding of Ohms Law is correct, it's pointless. And my personal experience with it seems to corroborate my feelings.
Under volting the CPU in my experience just introduces stability and reliability issues. I've personally never seen any battery savings from it, especially since the CPU should, theoretically, just draw more current (I) to compensate for the lower voltage (E). It's watts (P = ExI) that matter, and the CPU, if I understand correctly, is going to demand the necessary P for the frequency requested. So under volting either starves the CPU (it can't get enough P), or over currents it (it draws more I to compensate for less E). There are slight variations in each CPU, obviously, which may allow for a margin of under volting to be possible without issue, but the battery savings of this, I feel, are so small, any you notice are most likely a placebo effect. Your screen, and apps constantly polling the CPU or network are your biggest source of battery drain to worry about IMHO.

With an higher frequency the phone will use more power, like a pc processor when you overclock it so this is natural, but overclocking/downclocking has nothing to do with undervolting, MadJoe is right.
With JuiceDefender for example you can set your 3g/4g to shut off when you don't use the phone, it activates 3g/4g when you use your phone and at regular intervals in backgroud so it can fetch emails etc.
All automatic so you don't have to switch off and back on network connection every time.
As network connection is one of the services that consumes the battery a lot this is really effective and really improves battery life!
I've read a lot of complaints about these PowerManagement Apps using more battery life then they safe.
I don't know if this is right.
At the moment I'm running CM9 with modified auto-brightness options, auto-sync and 2G/3G/WIFI always on.
I'm really happy with the battery life I get, so I don't see why you would need a Battery Saver app with this phone.

Heh, so why did you get a smart phone. Some older nokia's that can only talk and text can last for weeks on one charge, if you want a model # I can look it up 4 u.
So guys, its a fact we have a small battery for our phone but I was wondering, how do you get the best battery life?
Just post anything! What ROM your using, what kernel, your kernel settings or maybe a tweak you found.
I want this to become a help center for people who suffer from bad battery
EDIT: Also, have you guys expierenced a difference with unfervolting?

I wholeheartedly believe in Greenify! I have it on my tablet and phone. I've seen a jump in battery life by about 30% since installing it. Not sure if you will have the same type of luck or not.
There's many factors that can be affecting your battery. More importantly it depends on the type of rom you are using, assuming it's sense based... Try using elementalx 6.6 kernel, it'll help your battery; tweaked with the right settings. Power saver also seems to help a bit.
This probably isn't what you had in mind but my best tip is to keep my old iPhone with me and use it for media consumption. That way my android always has a full battery for actual getting work done.

Why not just Greenify maps as suggested by others. Did wonders for my battery life, used to go to 15% in the evening, now regularly above 60%. I also use autostarts to kill some other processes that are launched by default
I'm using the stock Android 4.1.1 ROM unrooted. With my normal usage, I can get through two full days. I make sure to toggle off WiFi and mobile data when not in use, as well as toggle on the "battery saver" built into Sense. I also turn off sync for everything (Facebook, Twitter, etc) except for two Gmail accounts which only check for email. It's about on par with my old Nexus One that I moved from. Keep in mind, however, that I just got the phone and these might change, but this is what I've noticed thus far.
A combination of 2xBattery (toggles data connections when screen off) Tasker (toggle data in different times/locations) and Greenify.

When it comes to battery life, the basics really are the most important.
here's a couple:
1. Don't use auto brightness. It tends to keep the display super bright even when it's not needed. The display may very well be the component that draws the most power in the entire phone! Look for widgets that let you select manually (I use "Brightness widget - backlight" from Google Play and even manually, I set the brightest it can go to 79%) or apps that still let you have auto brightness but more controlled (Try "Yet another auto brightness" from Play Store).
2. Use a setup as stock as possible. I know some people are going to disagree with me , but having your phone as close to stock as possible will have the best proven battery life. I think some of the developers here do amazing work on custom roms and kernels, but when people report good battery life you should keep in mind that are so many factors involved that it's hard to replicate it if you want to. Carriers test their phones extensively to ensure good battery life, and while I am NOT saying custom roms and kernels is a bad idea, I AM saying that I believe a stock experience is a more proven option.
3. It also has been proven that undervolting does NOT help with battery life because not only the difference in millivolts is negligible, it may cause instability and finally a reboot, which just happens to be the biggest software-related power drainer.
Hope this helps
im running clearrom 6.5 but i havnt been able to get greenify to work really. when i install it, it only shows a couple apps that i dont really use to begin with. correct me if i am mistaken, but greenify will hibernate/shut off running apps and the apps that the greenify app shows are apps that are currently running?
Correct. If the app you want to hibernate isnt running you would have to run it to add it to the hibernate list.

I don't know if I agree 100% on that one. Undervolting can reduce the amount of heat discharge caused by too much voltage being provided. A hot battery affects battery life both in the short term, and the long term.
Yes, not all phones can handle undervolting (because they're already receiving a good amount of voltage out of the box), and will glitch and reboot, which drains battery.
But, for phones like mine (which I can generally UV by about -75mv without adverse effects), the reduction in heat can only be a good thing for my battery life.
Sent from my Evita using XDA Premium
Heat itself should not cause your battery to drain quicker. Heat is moreso an effect from the cause of something causing the battery to drain rather than heat causing the battery to drain faster. Heat can damage the battery which would cause it to drain faster... so what I mean to say is heat will often accompany the battery draining quickly but not be the cause of it. Hopefully this post makes sense.
Sent from my HTC One X using xda app-developers app
Yeah it's the damage caused by heat that I was talking about. I've heard a hot battery will discharge quicker though. But heat is also a side-effect of the battery providing the CPU with too much voltage, that extra voltage being provided has nowhere to go so that energy ends being dispersed in the form of heat. Which in turn damages the battery.

That is mostly incorrect. The voltage options we can tweak are not enough to make such a big difference, so you can and will still experience heat even with an undervolted cpu, provided the load is the same. And that's my point, that the difference in undervolting in millivolts is negligible yet one reboot can wipe out an entire day's worth of battery life "savings" from an undervolted CPU.
Ok well all I can say is UV'ing definitely decreases heat for me, particularly when playing games (which is when it heats up the most), and I can safely operate without reboots. Before you say it's a placebo effect, I check my temp regularly to verify it.

Well, don't think so. My phone also heats up during charging when I use it. I'm not sure if this work or not but you of course when you wan't can enable option that Nexus 4 has. It's like when a phone reach certain temperature a cpu/gpu clock is lower to prevent battery overheated.
I don't have it enable as mostly I don't play or do anything more stressful that will make phone hot.

dude you have a fit right...oh you sold it, still that device was about half as powerful okay 1/3 rd yet the battery temp with 0 activity and mostly in deep sleep is at 30 C.
now xperia L is way more powerful so should get a tad bit hotter too right(of course that's based on CPU activity) try it put is down for say two hours no charging , no nothing so that in deep sleep(lowest freq) also no 3g(that has its own daemon that eats cpu power i.e. causes cpu to work and hence battery drain and heat). wifi is okay(stable connection hence minimal cpu usage as no reconnections).
now check yor battery temp should be around 35C so your device is fine.
all this is based on stock heat and power management cant comment on custom kernels.

if you are on a custom kernel the best practice is to uv and NOT oc also change the governor to Interactive since thats far better than performance.(spimply put performance goes to top cpu freq even when not required and slowly scales down while interactive scales up fast and down fast at user touch events) for heating and basic phone wear and tear purposes.
and one of the main reason along with more ram(i mean lower bloat hence more free ram) that i want a cyanogen mod ROM.
Before and after playing candy crush.lol
When charging,it will up to 37-39 degrees
Qualcomm makes the MSM8230 chip that you see in L, there are 4 different "types" based on how it meets their quality standards. These are Slow, Nominal and Fast (Faster is on Higher end chips like APQ8064). The main difference IIRC between these types is how stable each can handle undervolting. CPUs that are "Fast" for example come pre-configured at a lower nominal voltage than a "Nominal" type CPU, and more so than a "Slow" type. IIRC, there's like only a -50mV difference between Fast and Slow out of the box, however Fast CPUs should be able to handle lower voltages than Slow-type.
This may explain why some people complain higher temp than others on account of same tasks. Although there can be other reasons. I'm not quite sure.
To find out what binned CPU you have, I recommend the following:
YOU MUST BE ROOTED! And installed busybox
1) Install Terminal Emulator
2) Reboot your phone
3) Open Terminal Emulator, and type:
su
dmesg | grep PVS
(if you don't see anything, try it.immediately after fresh reboot)
For example I've fast binned cpu
So basically, far as I understand I got Fast CPU which isn't going to be as hot as the Slow type due to lower voltage ?

if you are on a custom kernel the best practice is to uv and NOT oc also change the governor to Interactive since thats far better than performance.(spimply put performance goes to top cpu freq even when not required and slowly scales down while interactive scales up fast and down fast at user touch events) for heating and basic phone wear and tear purposes.
and one of the main reason along with more ram(i mean lower bloat hence more free ram) that i want a cyanogen mod ROM.

Bro no interactive governor present in stock extended kernel v3 :/ any other tips? @Dark Passenger

then go for ondemand the performance might be a tad bit slower than preformance governor but your battery life should be better along with the heating...also no oc.

I have a fast binned CPU
The result number shows the characteristic of cpu binned (AFAIK) Source : http://www.oppoforums.com/threads/qualcomm-cpu-binning-is-yours-slow-nominal-fast-or-faster.2842/page-5
1 : slow
2: normal
3: fast
4: faster
my tab become so hot hen i use it .. no matter at what frequency i set cpu!
im using next kernel right now ! but even at stock kernel its the same..
im wondring if there is any way to reduce this!??
thanks in advance

Few recommended tips:
1.Off your GPS, WIFI, DATA CONNECTION and BLUETOOTH when not in use. ( they are battery suckers)
2.Use original Samsung charger to charge your tab.
3.Watch your apps which consumes much processor and Ram, after that if they are not important just install them.
4.See your screen brightness, try to increase in daylight and decrease in nights.
5.Use power save option in your tab.
6.Try to charge your tab in switch off mode.
7.While charging don't do task, let it be only charge.
8. Charge only once a day completely without interrupt, rather than always keep on charging for few minutes and then few minutes and so on.. ( You will loose its original capability if you continue doing charging)
Edit: Make sure to uninstall apps which consumes more Processes.
You have to do it manually, no other Magic to keep your tab unheated. Follow above tips.
Underclock your gpu to 307Mhz or 153 mhz (through next kernel) , it will clearly reduce overheating amd battery consumption
