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.
JuiceDefender
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.

I use Power Controls widget.
Unless I'm actively using internet, I make sure to turn 4G data to 2G. That alone saves so much battery. If I want further battery saved, I disable internet completely with a touch of a widget. Now my phone will last a week just by what phones do best: Making phonecalls and texting.

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.

As above, anyone using higher capacity battery for their HTC Desire and it is tested and proven to last longer than the original batter? Can post the link to purchase the battery?
Thanks!
Before you buy another battery, have you read this thread about calibrating your battery?
And have you installed a rom that allows underclocking? It makes a massive difference.
I am now getting 20+ hours from my phone where as before underclocking I was getting 8 hours.
Same amount of usage, just underclocking when screen is off.
Erm.. I will go read about it, but because I want to retain as it is now, thats why I'm looking for an extended battery.

What kind of battery life do you currently get? Before (accidentally) calibrating my battery I was getting around 10-12 hours, now I'm getting around 36-42 hours.
I'm looking for one that can last me more than 1 day.

Well, I'm using the standard battery and have 26% remaining with "1d 10h" since unplugged (admittedly I haven't used the phone for that much in that time, just some internet usage, a couple of calls, but it's been constantly on WiFi or 3G to sync GMail).
Use SetCPU for underclocking, and use JuiceDefender to automatically turn off your data connection while the screen's off/locked.
It will still reconnect every 15 minutes to sync, and will remain connected as long as there's any continuing 3G traffic while the screen's off. Basically what it means is you're running one of the most power-consuming parts of your device only 1/15th of the time, which make a big difference. Text messages and voice calls come through instantly still - only things requiring a data connection like facebook, weather, twitter, etc will have any delay, and even then it'll only be 15 minutes at the most.
You can also try setting your phone to WCDMA-only, which means it won't be constantly trying to connect and maintain two radios simultaneously. GSM-only would be even better but depending on your carrier it might not work at all or might only work for voice.
With SetCPU try making a profile to automatically go into "powersave" mode when the screen's off, which will ensure the CPU never clocks up past its minimum speed during that time. It's still over 200 mhz, more than enough for anything you might want to do in the background. For normal operation, between 499 and 768 mhz as the maximum clock, depending on your preference, should be adequate and will save you a little bit of battery life as well all the time.
Also, download a widget to allow you to manually set screen brightness when you're indoors and the auto setting is useless. I have my screen brightness set to 15% while indoors and it's still plenty bright. I have the SLCD model, I don't know if that makes any difference.
My phone has been off the charger for 17 hours and 10 minutes. During that time, the screen was on for 2 hours and 29 minutes. I'm at 79% battery life with the standard battery.

Yours able to charge it properly?
A small update to my previous post... I'm now at 32 hours, 38 minutes uptime, 4 hours 44 minutes awake time (screen on). Battery just reached 60 percent. Stock battery.
Remember when you made the choice to buy an Android, you were in effect saying you wanted to have a highly customizable miniature computer. Just like when you customize [insert your desktop OS of choice] to suit your taste, you need to configure your phone in order to get what you want out of it - namely, better battery life than with the standard settings.
HTC's goal with the Desire was to have a showpiece, it runs very fast and it looks good doing it. But they designed it with frequent charging in mind. Since most of us here, I imagine, would prefer to charge less often, we just need to configure the phone appropriately.
If you want a guaranteed solution, try this:
- Install NextSense rom (it's free, latest version right now is 5.3 AFAIK, I'm currently using 5.2 still)
- Install JuiceDefender - it's free on the market and its default settings are, for a change, very intelligent and effective.
- Install SetCPU - You can get it free on this forum. Set it to "interactive" mode with a bottom speed of 245 and a top speed of 806 to start with. The default is 998 at the top, but 200 mhz doesn't make a big difference in this case except to help battery life a bit. Once installed, add a profile for "screen off" which sets the phone to "powersave" mode. This will keep it running at the minimum clock any time you're not using it. Nothing running in the background while you're not even using the phone requires more than the minimum CPU speed.
- Install the Brightness Widget by Curvefish. It's free on the market. Put its widget on your desktop and keep your screen brightness at 25% while you're indoors. 15% is what I use, but 25% is one of the presets so it's a bit easier. I have an SLCD display so the brightness I get on auto might just be different from what OLED gets on auto, I don't know, but in any case for me it's way brighter than it needs to be.
- Set your screen timeout to no more than 2 minutes
- Make sure any apps that sync data do so in a reasonable interval. +/- 15 minutes won't ruin your day for most things.
- Under Wireless & Networks, set your phone's connection to WCDMA-only (3G-only). For many people this results in an increase to both signal quality and battery life, since it allows your phone to only run one radio at a time, making a significant difference. If it doesn't work for you, it's as simple as turning it back to the default setting.
- Disable haptic feedback and see if you mind the difference. Making all those little vibrations takes power too.
- Finally (obviously) don't run a live background, but you probably already know that.
Doing all of the above takes an hour or maybe two at most to set up and the difference in battery life is tremendous. It's simple to do, I worked out all of the above on my own and I've literally only had the phone for 4 days now I think, never touched a smartphone before in my life let alone an Android.
Give it a try, you have nothing to lose, and it will probably save you needing to buy a battery. Or, if you still buy a double-capacity battery, it'll mean you can run for like a week on a charge.
edit: also make sure to get the latest version of the radio driver, I don't have a frame of reference for comparison since I updated mine right away, but apparently it makes a fair bit of difference and probably gives you a more reliable cell signal in the process.
In case you think I'm exaggerating, here are some pics I just took.

"Ideal" settings are basically the way it's configured by default. You can't improve upon them much even by getting the "premium" upgrade unless your phone is rooted... but SetCPU is a better choice in that case anyway.
Just install it, hit "enable" after it's done auto-detecting your phone's capabilities, and you're done. It's really that simple.
Be sure to add it to your task killer exclusion list if you use one.
You saying the default option is for SetCPU or Juicedefender?
So just download the free juicedefender is good enough for me already since the pro version is more for rooted phones? (mine is not rooted)

Yes exactly. The pro version unlocks some more customization but ultimately won't add a whole lot to your battery life no matter how it's set up. I mean, beyond what the "regular" version does.
I am playing a bit with underclocking my DS (Using UNITY v4 kernel atm, will update to v9 later).
However, I'm figuring out the usefulness of it (to extend battery life mainly).
Does it really save battery life? I'm already using JuiceDefender, and its SetCPU function.
Or is it not very useful since the most batterydrain comes from radios anyway.
What are the best values for it?
What's the standard clockspeed for the DS? And what is the best Max IDLE clock speed?
Well, i wont underclock at all.
First of all there is no need to do that to get good battery life. You can do lot other stuff to do so.
Under-clocking is risky as it might now have enough power that needed to the phone. that means that some stuff might not get processed like calls and stuff.
Right now with me using miui i get life for about 3-4 days.
Standard clock speed is 1,000mhz.
I have mine underclocked to 600mhz during idle times and it's perfectly fine.
Never had any issues at that speed and it keeps my Desire S much much cooler which can only be a good thing.
As for it's ability to extend the battery, I don't think it does so much in my case. I typically run WiFi overnight and G/3G/H during the day and my display usually chews up 60-70% of my overall battery usage even on a very dark screen.
I'd pick a setting that you feel comfortable with but have low expectations of the benefits.
The only time I use underclocking is for using Google Navigation.
On a hot day using Navigation for over a couple of hours, my DS would over-heat and restart (usually as I was approaching my motorway exit). So I have Tasker dialing back CPU to 768Mhz when using Navigation, and it does seem to help the phone run a little cooler. I no longer have to take it out the case for example.
Using the smartass governor (I believe) automatically knocks the CPU back to 240Mhz when sleeping. Not 100% on that though.
I'm currently testing a new kernel, and I spent an entire charge cycle on 'Smartass' and then an entire charge cycle on 'Powersave'. Aside from lots of lag on the latter one, the battery life was pretty much the same!
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.

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.

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.

Thanks man!
Will give it a go.
I'm not really sure on what the value of these apps are.
Letting my phone do whatever it wants when I'm on wifi and my phone is sitting idle, my phone uses around 1%/hour of battery life.
Some portion of that is all this app could really save then, right?
Why bother if, in exchange, I'm possibly having delayed notifications, apps not updating in the background, etc.?
Sounds like a bunch of BS to me.
I'll be shocked if this makes any discernable difference.

This inherently means the app will take control of the CPU/governor adjustments. A kernel such as KT with an app that LOCKS frequencies may prevent this, but also will render the app useless.
They aren't concerned with the same things as we in the rooting world are. We want to push as much processing power as possible while using the least amount of electrical power needed, not slow the device down while hoping ppl don't notice. Lol..
I too experienced battery drain from this app.

tryed for about 1weeks.
After the learning mode...it started to appear as one of the most stealer of battery life...with 12/13% of daily battery usage. Disinstalled lol ...and my phone seems to be turned at a good battery life
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?

Try Greenify in the Play Store. It seems to help for me.
I use a Tasker profile that will disable mobile data when my screen is off and when it's not being used. Don't know if it helps or not I don't worry about battery because I have a a portable battery pack charger thing

Pretty sure there is already one of these.
Elementalx kernel, greenify to hibernate Google maps, use WiFi as much as possible.

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.

I've noticed on CleanRom that maps uses a lot of battery %. I've never looked into it, but I'm guessing you've found the same problem.

Ya I have, usually turn off location services until I need them

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.

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.

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.
