Amazing battery life!

I'm just wondering if anyone here is getting the super amazing battery life that I'm also seeing. I'm running Virusrom (basically just themed stock rom with no bloat) had my data connections off, and screen off clock speed set to 200MHz (using overclock widget to control speed)
I got through 12 hours on 3% battery. Is anyone else seeing this?

what overclock widget you using? Just curious...
Bleeds

I would love that...

If I never touch the phone I get this
But unfortunately I can't leave it alone xD

seems alittle fishy since the processor cannot go below 245Mhz.
plus what do you mean by data connections off? No LTE or 3G?
Or do you mean you disabled always-on mobile data? I myself usually drop 10% in about 7-8 hours with that enabled and normal use, with SetCPU telling the processor to run at 245Mhz when the screen is off.

Yea, 245mhz, I didn't have my phone on me, and couldn't exactly remember. No data means no wifi, 3G, 4G. It just could receive/send calls and texts. As for the overclock widget, it's just called "Overclock Widget" in the market.

I am on a stock Tbolt and have disabled the lock screen and GPS when not needed and am getting at least 12 hrs with life to spare. MUCH better then my first day of use

1 1/2 more hours I will reach 12 hours. All I did was to follow this man's tips. I still have 30% left. I'm sure it's nothing new to some of you but new to me as I never had to do this w my old Samsung or Nokia phones.

I have
1. MS Exchange sync every 15 min
2. Gmail sync
3. Facebook sync
3. SipDroid calls for about 2 hours
4. Pandora streaming for 1/2 hour
5. Surf net about 1 hour
6. Xda app about 1/2 hour
I'm happy and i'm still stock TB!!!

Unless I'm actively using data, I always have it off. Well unless it's on charge haha. As for sync, I don't even sync email (gmail), or anything. I don't really count contacts or apps as syncing as it's almost a one time thing. Most people tell my i Baby my smartphone, but I'm the only one I knew that could get 3 days on my Dinc 3 days no charge on stock battery haha.

Uhh... congratulations?! You made your device entirely useless and got trough 12 hours on 3% of the battery.
What is the point of using your Android smartphone without data all day? Is this a pissing contest to see who can disable all of the core functionality of the phone and see how long the battery lasts?
I turned my phone off the other day and when I turned it back on I used .5% of the battery... woah!! That is absurd battery life for such an awesome smart phone.
Sorry for all the BS... but honestly, why go through all of these lengths to prolong battery life longer than 12-18 hours. It renders the device useless and it no longer provides service to the user. I completely agree with optimizing the device (running custom kernels when they become available), using SetCPU profiles, etc... to a certain extent. If those optimizations impede on performance or functionality in any way then they are not worth it to me.
So ultimately, why sacrifice performance and functionality for the sake of ridiculous battery life. As long as you can make it through the day, then no worries. I charge my device every night anyhow.

I've started using this widget as well, I'll find out its effectiveness in a day or two once I leave it off for a while (like overnight). Only complaint I have though - every time I turn the screen on, it says it's been granted su permissions, right above my dock. Is there any way to turn that off? It's just kinda weird too, if I go to show off the phone it looks bad.
Edit: I do have data usage in the background though.

Well honestly, I am around a computer most of the day, sleeping, or at work (can't be on my phone) I was sleeping most of that 3% loss. When I'm near a computer I tether so that charges without me thinking about it, and in my car I have it on charge because of the battery rape of GPS and 3g/4g. It's still a fully functional phone with no data... I can text and talk all I want. And it's not like I don't toggle on my data when I need it. I just don't see the point of being THAT connected to technology ALL off the item, and I'm a programmer, and an I.T. gupy >_>

In the Superuser app you can change that notification. Also, there is a preference for the notification letting you know the clock changed in the widget's prefs. I turn them off. I normally use a smartass kernel as it works with much less power, but this is better than not having it for now IMHO.

This. One of my pet peeves is people bragging about amazing battery life when they're using their phone as a paper weight. Why buy a smartphone?

I'll tell you why.
1. 4g tether that rivals my cable internet, and I can have both at the same time
2. I always have data and GPS, which is amazing in my car or anywhere.
3. Why no I have to be strung to the internet 24/7 and not just when I want to? It's always there, at the toggle of a button. I'd rather not be lazy and toggle data versus looking for a charger every few hours >_>

Thanks, I somehow missed that setting when I was setting it up earlier.
Also, I kind of agree with what's said due to the fact that 75%+ of the time I'm awake I'm at a computer. I don't need to have my phone do much more than texts/calls during that time. Why waste battery for that? But when I'm not at a computer, I need it, and that's why I have this phone.

Not a problem. We all miss something at times
As for "needing" data, I personally find myself "wanting" it. I don't have anything that I can't let go of on the internet while I'm at work (can't use my phone for anything but texting once in a while). I always enjoy my data, and use a considerable amount of data, but it's either tethered or plugged in as I'm driving, and may as well. I guess being a minimalist is against the law now a days

i get great battery life stock not rooted but when i added adw launcher and gingerbread theme with ginger bread keyboard i went 1hr and it was a 60% and i never touched it so stock my battery is awesome

I think you've missed the point. Noone will last even more than 6 hours if you don't do the trickle charges or whatever you call it. That's the point. I know you reply to OP but just want to point it out. After charging it the right way, you will certainly last 8 hours at least which then bring to your point "I charge the phone every night anhow".

in settings, there is a setting to turn off data and wifi after a certain epriod of time when the screen is off, saves battery very well.

[Q] Help with battery usage / drain, how to increase battery life

Ive searched around and this seems to be a common issue, I tried the factory reset even the htc battery conditioning where you charge fully turn off then another hour back on for 2min off again and charge for another hour with no positive results, I read online some ppl are getting -1/-2 mah an hour I have never seen single digit in my phone.
I included screenshots of my battery drain even adjusted the app to read 1500mah, anything else i missed in settings? Also went into phone information in the Tests menu set it to auto instead of GSM, also with SetCPU I tried underclocking with little change to mah usage, running out of ideas...
Currently its rooted with GingerBreak, and CM7 with #48 nightly installed, any help would definitely be appreciated.

How many hours is your phone lasting on a single charge?

Lately between 5-7hrs one had about 8 and half hours a handful of times

it's true that if you constantly use the phone nonstop like watching youtube, browsing, playing games, etc. the battery won't last longer than 4 hours without getting an extended battery, heck just using moderateley the battery will be about 50% by the end of an 8 hour workshift, but what I found that will extend the battery life with moderate use are these...
1. Turn of wifi, bluetooth, gps, sync. (contrary to what ppl say on this forum I find that wifi eats way more battery than being on 4G)
2 Disable background data. (The only thing I actually need background data checked is to use the android market or maps when I need to, with it off it's a huge battery saver)
3 In settings choose to use only 2G (This will increase battery life 4x and Tmobile 2G is pretty fast, just like 3G)
4 Download Opera Mini (Since you'll be using 2G to save battery you'll want to surf the web with a browser that is super fast using slow connections, and Opera mini is second to none. You can always turn on 4G when you want to have fast video streaming but then you eat alot of battery again.)
5. Install Auto Airplane Mode (you can turn auto airplane mode on when you're not gonna be expecting calls such as at work or when you don't want to be disturbed, hell, if you just want to save as much battery as possible. Since Auto airplane mode disables the radio and data completey which is the number 1 cause of battery bleed with it on from a full charge unplugged you'll still have a 100% when you wake up your phone after a day.)
6 Install juice defender (free is fine)
7 Don't use Lookout Antivirus (I've found Lookout drains the battery quick, if you want an antivirus that doesn't eat the battery try AVG. I prefer AVG because I notice it does not drain my battery like Lookout.)
This has made my phone last more than a day on stock battery with moderate to light use. If I think of more tweaks I'll add later

This is ridiculous. If you have to turn off all those features, then don't even bother getting a smartphone.
My tips are:
1- Set brightness to auto.
2- Avoid Skype and other apps that usually appear as On going on the status bar.
3- Get rid of any task killer. They actually make the battery life worse. Don't worry about tasks running in the background, the OS takes care of them. If you wanna quit an app, try to look for a quit button by pressing the settings button when the app is on the foreground. Otherwise, just press the back button below the screen until you get back to the home screen (for some reason this seems more efficient than just pressing the home button.)
4- If you don't use IMs, get juice defender and set it to disable data when screen is off. It will turn data automatically on once you turn the screen on by pressing the lock button on the top of your device. Note that this is different compared to auto airplane mode, with Juice Defender you can still receive phone calls and text messages when the screen is off.
Last but not least, consider purchasing an extra battery and/or car charger.
Mine usually lasts for about 12 hours with moderate to high use. Almost all smartphones have short battery life if used heavily.

Yea that's awful. Do you by chance have your brightness set extremely high? And how is the cell coverage where you usually use your phone?

I think all of the advice above is valid and will save your battery. The question is to what extreme do you want to go? I tend to agree with donatello88 that there comes a point when you get so paranoid about battery life that you may as well not have a smartphone because you've turned off most of its features.
Get rid of any task killers, battery monitors, etc. They are simply churning thru clock cycles and that uses more battery. Set email, Facebook, etc to check for updates less frequently. Either use auto brightness or manually set your brightness to about 25-30%. That should b bright enough for everyday use unless your in bright sunlight a lot. Use juice defender if you like. And be wary of antivirus apps. I've heard some can suck ur battery dry.
If you do those simple things and are still getting only 5-6 hours then I'd be taking it back to T-Mobile ... unless of course you're on your phone without ceasing. In that case, what can you expect? Lol

Ok with the tips I just mentioned above, I got a chance to put it to real world test. I caught the bus to my son's grad ceremony and reached there at 4pm ceremony didn't start till 6pm so those 2 hours just surfing the web reading articles and forums I was down to 90% battery. Didn't know how long the ceremony was gonna be so called my sister on video chat using tango and spoke to her for about 20 minutes. Did some more browsing using opera mini set to only use 2g for another 2 hours, my don came out, I took some pics and video of him turned on 4g to video chat again with my duster for about 5 minutes, and after 4 non stop hours of consecutive use with screen on, I'm now at 71% battery life. I'm at the bus stop now on my 12 mile commute home and I'm confident the battery will give me more entertainment until I get home. Awesome! You don't have to believe me, just try out my tweaks and you'll be amazed.

Everyone thanks for all of the help and tips, today was the first day I saw 10hrs+(included screenshots), I had my screen on auto and after some reading saw that with CM7 it doesnt work well so I have changed it down to 20-40% depending on where I am, turned off background/auto sync only turn it on when I need it and uninstalled the app killer I was using also changed a few of the SetCPU profiles.
Im not really a heavy user just wondering if having 3email accounts set to update every hour would be a battery drain too? I mostly text/email during the day and talk about 1-2hrs depending how busy I am at work.
Again I thank everyone for pointing me in the right direction...unfortunately at home I have 1bar to none for service so I do depend on Wifi calling which im sure drains more juice, also at work since it in a high rise not too much cell signal so wifi on most of the day...

Hello risho,
I was having the same kind of battery life... After 3 months of research, I collected all valuable tips.
"Valuable tips" means: tips that do not need constant involvement from your side (you don't need to go switch on/off things, etc..) and also that leave you with a very functional phone (you have location when you need it, you have e-mails flowing regularly enough, etc...)!
With these tips, I am now lasting from 6am to 11pm and at 11pm, remaining battery is 10% at least!
Go and check my thread: [Ultimate GUIDE] Increase your battery life on Android!
Enjoy!

Fast discharging

I896, Rooted, factory Gingerbread.
I have a Captivate and a Tab. Both Wifi only, no Sims, Airplane mode on, Bluetooth off. Machines are on but screen is off. The Tab looses 3% over the course of the morning and the Captivate looses 20%!
I'm running regular 'power user' type apps; Titanium Backup, Tasker, LauncherPro. If there are any apps notorious for secret batt consumption, let me know what to avoid.
Running SystemPanel Lite - I can't see any app that is taking up more CPU time than normal that would explain this kind of drain. The battery page shows a good proportion of battery use display and wifi. In one instance I used the Captivate so little that display showed less use than wifi. In the course of just checking phone power consumption, the display use percent way up, just like expected (Just to show that wifi was really doing almost nothing) and still I had lost more than 15% of battery over the time when the phone was supposedly idle, not connected to anything with the screen off. Some ghost is sucking the life out of my battery. Grrrr. What could it be?
I loose 30% in a night with wifi off, backlight set to absolute min and nothing runninng or syncing.
I don't get it. Any ideas? What do I try next?

His tab is running Android too.
If you don't have anything helpful (or knowledgeable) to say don't say anything.
Op, download watchdog from the market, (system panel is kinda ..meh.) and see if there us a rogue app munching battery.
You may consider flashing a ROM see if its just that firmware/kernel reacting to your phone.

Have you tried Juice Defender?
Also, check to make sure you don't have applications constantly running. What version of android are you running? Check in system settings -> status -> somewhere in here you can check the battery status and what applications are pulling the most juice ... From there if one application needs to be removed you can action it ...

Also try the "Battery Calibration" app in the market. It's free.

my captivate running cm7 STOCK will drain down to 20% from being idle for 12 hours
my battery will also drain 30% from 45 mins of wifi only use.
doesnt help him but thats my experience from my captivate

Menu -> Settings -> Wireless and Networking -> Wi-Fi settinngs -> Menu -> Advanced -> Wi-Fi sleep policy
Set it to when screen turns off.
We have to switch that every time we flash. I really wish it was default. Some ROMs also have background data control, but it's usually when wi-fi is on so it shouldn't be a problem.

You do know that cm7 doesn't have the proper hardware drivers from Samsung so the battery life is known to be HORRIBLE right? If not you should really read up on the ROM you're using
Flash any touchwiz ROM, especially a native I897 build and you will see a dramatic increase in battery life.

I'm on CM7 and am going on 27 hours with moderate usage.. Granted, I have the 1800 mah battery from the Sprint Galaxy S2

trying flashing to pinnacle. I too have battled weird captivate drain issues.
if you wanna try CM, read my thread:
http://forum.xda-developers.com/showthread.php?t=1364357

I've held off replying as I was trying a few things and figured I would report only once I was done.
I found and ran Battery Calibration, just before I read the post. Between that and turning Wifi sleep policy to off with screen off, I had a great weekend. I was getting a day and a half out of my phone, which considering the use, was very acceptable. I was getting about the same drain as my Tab. I had 1% battery drain after 4 hrs of screen off time. That seemed fine for me.
I got back to school where I teach and yesterday the phone drained as fast as it has before. Interestingly, it continued its rapid drain even after I left the school and went back home. So, it died at 4am this morning. I heard it shut down. The school has at least 4 routers, two of which have 5k access options. I know if I choose them, my laptop drains way faster. Is there a way to limit my wifi connection on the captivate and not use the faster 5k connection?
But, this still doesn't explain why, even after I leave the school, the Captivate continues to drain when it is 10ft from a single 100mb wifi router.
I'm almost ready to try a custom Rom, but not sure how that will affect my ability to use it as a phone, once I get my Sim activated. Still new to this all.

You think everyone running a custom ROM doesn't use the phone?
Shouldn't affect your ability to do anything...

The WiFi and cell radio do increase power on lower signal as we know, but that's not always the cause of drain. I remember times using Froyo when kswapd goes nuts for no reason, or trillian, email, twitter or some other app just starts using massive CPU. Many apps are probably never tested on a system that has no connection most of the time. That's where all the utilities come in handy to find the culpret. OSMonitor can help find CPU hogs. TiBu can freeze apps, or uninstall them temporarily. Juice Plotter can monitor drain over time (newer Androids have something like it built-in). It takes some time to find it, but newer versions of the OS make it easier and have less trouble.
Also the battery % is only estimated. I'd trust full to empty time rather than 90% to 80% time as 10% use since it's not really as linear as we think.

Not to point out the obvious, but it can be the battery itself that has the problem. They aren't exactly manufactured to NASA standards... well, maybe their standards lately, but the point is, sometimes the ghost you're chasing is staring you right in the face.

Extreme measures for better battery life

I finally decided I would take some extreme measures to aide the BL of my Androids. I have an HTC Inspire and HTC HD2 with Nexus S Android. The HD2 isn't all that bad...much better BL than the Inspire, but I wanted to apply this measure to both phones. Will it help? Only time will tell.
I started by removing all screen widgets. Then I sorted the screen icons so that a minimum of homescreens were needed...got it down to 2 homescreens. Then I deleted all widgets without apps not able to be opened through an icon. Then I went into Applications manager and cleared and stopped all non-used apps and services. I also deleted all duplicate services such as OEM email accounts and their associated syncing....using add-in apps for them. (example: built-in apps and widgets like Facebook, Twitter are uninstalled or disabled and am using another combining app like Seesmic. Same goes for the email app)
What I currently have is an Android iPhone. I'm using only icons on the 2 homescreens. And this makes me understand why Apple refuses to use widgets and stick with icons...to preserve BL. I hope this will improve the BL of my Androids because it is purely horrendous. And it is horrendous with all Androids I've tried and used.
Until the recently announced battery tech breakthrough is made available, this might have to be how Android is used from now on. But I doubt these extreme measures will actually help.

What is the difference between a widget and an application?

An application is a single, whole program package that is loaded into the phone. Examples would be Tapatalk, the default Calculator, and Angry Birds.
An application can have one or more widgets in it -- a widget is an interactive thing you can place on the home screen. It can give you information, and you can tap on it to change what it says. A good example of that would be Beautiful Widgets, or the little Android guy that tells you about how to use your new phone.

@Marty, how long was your battery lasting prior to the "Extreme Makeover"? Mine currently will last me 2 days. Admittedly, I've not loaded a lot of stuff on the phone yet, and I have the power saver mode start at 70%...but I only need to recharge every other day.

My desire lasts around 2 days with moderate usage. But on a good day (read: many boring moments), it's completely depleted by the end of the day. My biggest battery drainer is whatsapp, if I uninstall the app my battery will last a LOT longer.
If i really need my phone to last for a long time (when Im on a big trip or on a festival) I always use JuiceDefender with a very strict setting. This is a big help, but not for everyday use

whats the point? Where ever you sleep you have access to a plug/usb w/e so whats the big deal ? how hard is it to charge the phone every night? even thought my galaxy s2 hold battery for 40hrs+ i never need that :|

Ive dont the same thing, I also found some build prop and init.d tweaks that improve battery life.
my brightness is always at minimum, i have only one widget,
My battery could last two days BUT i use my phone a lot. like its on for 7 hours with 4.5 hrs screen on.

Hilarious.

ther have been many apps and disucssions on BL. heres some common tips.
screen to lowest brightness possible setting. background data always off unless using market. disable -use wireless networks- options, no gps, no location. also turn off *back up my data*. wifi always off not in use. screeen timeout no more than 2 minutes. turn off animations and transitions. setcpu with moderate settings (if you can do a screen off profile it will be beneficial but beware Sleep of Death.) no live wallpapers. minimum widgets or none. minimum homescreens or 1. startup manger. adfree. location cache app. and battery calibration to get the most juice.

the issues seems to be alot with hardware the Htc inspire and HD2 have 1250 Mah Batteries , which are very small.

If some people are just like me... I can kill at 1800mah battery in 5 hours even at full charge...
I do everything on my smartphone. So anything to save the battery is a good way.
I have the Galaxsy S II and I've managed to drain the battery in 6hours of usage and since I'm not near a power source most of the time then yeah I need all the juice....
I don't sit in an office or am near a power source 80% of the time. I usually carry 2 spare batteries with me and a charger for them just in case.
Cheers! (Extreme power user).

Whats the point??
Here is my daily usage :
Alarm goes off at 6:30am (phone gets unplugged)
Blahblah (at work) reply to emails and messages throughout the day, on twitter A LOT (plume premium)
2 calls approx 30 mins each
Play some games at break and lunchtime (Drag racing KILLS my battery, a bit of plants vs zombies, grave defence HD and maybe some pinball deluxe)
more emails and twitter
another 20min call
a little more gaming while im waiting on customers (1hr or so??)
6pm go home for 6:30pm
BAM! battery is at 10-20% and i need to plug it in again.
this is a typical 12hr day for me and im sure others have longer days and i would appreciate not having to rush home (sometimes) if im expecting a call.
so as far as im concerned anything which will save some precious battery on my devices is appreciated.
btw i have reduced my homescreens to 3 and only have 2 widgets running and that has made a great difference to my battery life (esp. on the DHD)

Basically kill factory and carrier bloatware and you are getting better.
One thing I was amazed about was the eBook reader that comes with our Galaxy Tabs, and suppose others too.. it always working even if you dont have or use it.
And remember, the screen is what takes most out of your BL, always. Lower brightness? Get a better ROM with no bloatware and maybe undervolt the screen.
Homescreens dont change a bit. Widgets do, if they update a lot.. more than that notification stuff do. Like if you use a antivirus or antisomething, just check of notifications.. check of any unneeded notifications.
Vibration theorically is what consumes the most.. but since its not as used as the screen, you dont even compare them. But every little bit helps. Check off keyboard clicks and hepatic feedback - vibrations.
Wifi, bluetooth, data... don't actually consume much.. actually it's better if you leave a service stable on, than keep sleeping and switching it. So leave wifi always on, no sleep policy. But when you go out turn it of so it doesnt keep scanning all the time (unless you want to ).
Just like any PC, the more you install.... Just check what you got going on, learn how to check processes and services that keep on all the time, and there are some utils to help stop some crap from starting up. I use ROM Toolbox and Autostarts.. some stuff get activated just because you plug you device to charge!
DONT use task killers... dont let anything like that keep running... and no, GMail push notifications wont use any batt. Maybe pop/imap emails always pollling will use some.. but probably nothing compared to the examples above.
Cheers for my 2 cents.
EDIT: and after Xmas, remove those animated wallpapers!

Is Juice Defender a task killer? Not really sure what is it but I've been wondering about that.
Juice Defender Ultimate has been giving me about a 1/3 more time with screen on max. Why is my screen on max, because I was trying to drain the phone. It's on about 40% now which is still pretty bright. I wouldn't be mad to get more life but I think 20+ hrs with moderate use isn't bad. I think the most I did was search the net about 4 hours total. But I was also, customizing, so it the screen was lit for a while.
This is a TMO GSII I'm talking about.

There are a ton of things you can do, but the truth of it all is that our 3G/4G radios pull so hard they drain the battery, which is why you were on the right track when you disable active since, Facebook and Twitter.
The main two things I do, is
1. add a widget for turning off 3G or 4G (If its in your area).
2. Installed Startup Manager ( it disables startup programs in the unseen background, (my phone is rooted)).
by doing these two things I am able to get 17hrs+ on a standard HTC EVO 4G battery. Keep in mind the more you use the Internet the more it will drain your battery. So I only turn the internet connection on when I need it or the app needs it.
*I also only use one screen and remove unnecessary widgets but I find that doesn't help the battery life all that much, (my personal Preference)
*When I or my sons game on my phone I put it on Airplane more which turns off all Radios including the Phone (call/text)
*Drawback to turning 3G off, you have to wait a few second for the internet to come back on and MMS won't download through your messenger unless have it one.
I've been off the charge for 8hrs and my battery life is still at 65%
Sorry to be long winded but if I know anything its battery life

Completely agree. What's the point. Either you don't use your phone for ANYTHING, and watch the battery last for 2 weeks (literally), or you use it so heavily that it lasts only 2 hours....
I was sick recently, and as such couldn't use my phone (I couldn't open my eyes without getting dizzy, and even closed.... still was). Suddenly my HTC Inspire 4G used only 20% of the battery in 10 hours. The previous day, heavy mail, "friendstream" (HTC's facebook/twitter/etc app/widget), listening to music (well, audiobooks) for about 8 hours, and I had only 20% left. And i've found that overclocking the phone to 1.3GHz helps more than any other tweak.
Don't get me wrong, I'm obsessive about using my phone *and* getting awesome battery life out of it. But the ONLY way to true "maximize" your battery life is to *minimize* your usage. But then you might as well buy a feature phone.
And I know a few people with iPhones. a 3GS and a 4 and a 4S. They don't get any better battery life than I do. Heck, they get worse. Even under the same type of usage.
For me, the problem isn't the usage, isn't what's running, or what's loaded (but it does help/hurt). The problem is that battery technology has NOT kept up with consumer needs, or IT development. Your battery is dying as soon as it leaves the factory. Your battery is dying every time you change it. Especially when it gets hot. your battery dies faster when it's cold outside. We need better energy storage medium. Period.

Buy the biggest battery I can find on eBay....
Use the fsck out of my phone all day and have plenty of battery left.
Problem solved.

<<<< What he said

I don't think the use of WiFi could be overstated.
On my Skyrocket, leaving Wifi on (indoors), it'll sip about 1% every hour. I go out and have 4G LTE on, it drinks up about 3% every hour.
Minimizing widgets also helps. I saw noticeably better battery after removing my facebook and Latitude widgets.
The screen also sucks up the most battery. Turn it off on every occasion. Just turning it off instead of letting it shut off by itself has made a difference for me.

Battery technology has kept up with usage. However, battery size in relation to the power draw, has not.
Compare the size of the back cover on your phone, with the size of the battery. Why is the battery this tiny little 2" square, when the phone is 5" tall and 2.5" wide? Why aren't batteries the same height/width as the phone? Why isn't the battery the same size as the back cover? Why aren't phone manufacturers optimising the size of the battery (meaning, making it as big as possible)?
It would be so nice if phone manufacturers would stop with this stupid "race to the thinnest" crap, and started:
- releasing phones that are actually comfortable to hold like a phone
- releasing phones with batteries larger than a pack of matches
your battery dies faster when it's cold outside.

Actually, keeping a battery cool makes it last longer, not drain faster.

Best Battery saving tips -

Hey guys, I know hussainmicromaxa60 has recently posted a battery saving tip post, (copied from cnets post) but really what cnet said isnt of much use. i.e switching off GPS doesnt save battery as android only uses it when it needs to, the rest of the time its off anyway. So I thought I post a youtube video here with the tips I have found actually useful:
http://www.youtube.com/watch?v=sUAlbkvlVQ8&feature=youtu.be
The tips are to use programs like cpu spy and betterbatterystats, to find and stop partial wakelocks,
switch to 2g when you are near wifi
Use an app like screen filter when indoors or and at night
And finally check sync intervals for apps and change them to a longer time period.
Let me know what you guys things of the video.

best battery life
I have read the new forums that wipe battery stats would extend battery life. I have tried that repeatedly yet I'm not so sure that he does. The jury is still out on this. Perhaps someone that knows better can advice.
I have also read in some forum and I think this comes from T-Mobile, that wiping battery stats does not actually extend battery life.
The only certain thing is that if you want better battery life you must buy a better/bigger battery.

Well, I'm sure some applications can really help your battery (Juice Defender, Green Energy, etc..), however, I gave up all that and I'm using common sense (not a market app).
So, only use wifi when needed, wifi drains battery really fast. Same goes for the use of 3g. Sometimes it's like a taximeter when you turn it on.
Brightness, it does spend battery, keep your screen confortably visible but not on max brightness. Don't know how far "self adjust" works for everyone, but CM7 allows you to personalize the self ajudsting methoods more to your needs.
Voice calls don't spend much battery, what does spend is apps, games (specially the ones with nice graphics and stuff), network, and so on.
I don't listen to music on my phone so... I'm not sure how much battery it takes to use it as a mp3 player, however I have an iPod for that, so I avoid listen to mp3 on my phone.
GPS... hardly use it... only when needed.
So, for all the "extras", only when needed seems to to do the job.
Also, disable "vibrate" when you don't need to. Like, cm7 vibrates on some awkward ocasions, like when you pick up a call, hang up, etc... if you don't need it, disable.
It's really personalizing your rom options to the point where you don't need additional features just for the sake of having them turned on.
Use your phone and features on a "when needed" basis and your battery life will be be longer.
Also, widgets, they do use battery, and sometimes, more than needed. The ones that use Internet (wifi or 3g) use more battery. Facebook, twitter, etc...
One more thing, about the CPU governors this time. I usually keep mine on a on-demand. When it runs low (under 20%), it switches to "conservative". It does get sluggish, but you get a few extra hours out of it. It's usefull for emergency voice calls.
Try to "underclock it" when not using (screen off, charging, etc..) and use overclock if you're really sure you need to. Most of the times the max allowed cpu without overclocking is more than enough, unless you're a performance maniac and need the best of the best performance out of it, there's really no need to overclock it.
If you play a lot with your phone (like me), at least keep a usb cable or a charger with you.
Hope it helps
PS - Some apps allows you to customize the way your phone spends battery. I find Juice Defender really cool for that. Spend about 20 minutes tweaking it for your needs, and the next couple of days with final adjustments and you'll notice improvements.

nice

I have tried several battery saver, but all the same .. no one gives optimaliasasi on my samsung.. sorry for my bad english

wiping battery stats will not improve battery life.
screen brightness is the major reason for battery drain. so keep the brightness as low as possible

Things like juice defender ect can be helpful i guess but i have never seen much of an improvement, in terms of wiping battery stats, all it really does it to allow android to read with better accuracy the amount of juice you have left, so it does not increase battery life at all.
Things like cpu governers etc is quite advanced, and I dont know really much about it, but as long as you keep under control misbehaving apps, switch to 2G when needed and dont have apps checking every 15 minutes for new data, you can get through a full day, no problems.
Also, keeping your battery in good condition always helps. First few charges, charge overnight, first week or two never let it go below 50% charge, and keep total discharges to an absolute minimum, and you should have a battery that wont degrade too quickly.
