I did with my 2.1 same as 1.6. removed unwanted apps. using taskkiller and autorun killer same way. holding wifi, gps, and bluetooth off. everything i do is same. I'm not using live wallpapers.
With 1.6 there was no problem keeping phone uncharged for 4 days.
With 2.1 it's like one day or little bit more.
What can i do to make battery not drawn so quickly ???
You shouldent use a taskkiller on 2.1 since it does that by itself. Using taskkiller will make your phone to force start apps again to shut down.

4 days uncharged!?!?
My phones battery runs approx. 10 hrs standby + 4 hrs of use (screen on) on a full charge..
I also think that there are some battery issues.. On 1.6 it would last about 14-16 hours. Enough to use it during day and keep it charging overnight. Now I have to charge it twice per day Looking at the built in what uses battery app it says that the major draws are phone not in use (30%), screen (40%) and wireless (15%).
Any suggestions on what app i can use to micro manage what is using battery even further?
Found a program http://ziyang.eecs.umich.edu/projects/powertutor/UMLogger-release-signed.apk that does exactly what i wanted. Shows battery usage per system wise (lcd, wifi, 3g, etc) and can also get down to real details, showing battery usage per process. This way you can determine what is hogging that battery.
I left my mini in standby mode during the night and in 10 hours it only used 5% of the battery indicator. in theory I have 200 hours in standby... dont have any issue with battery myself.
In daytime use the battery goes way faster but still can do a day without charging with moderate use (3g, wi-fi enabled)
I have all the auto-syncs off and i do use the task killer but it is set to kill himself 2 when i hit the kill button.
hope this helps
Be careful, to use a task killer or similar on 2.1 maybe worse than you don't use it... it isn't recomended from 2.0 and above to use a task killer, because of the own task administrator of Android... Remember that this operative system "learns" your most used apps... the less ones... and admins the process, so be patient and wait some more days and some reboots...
Certainly I have to say that I realize that my batt is a little bit longer... but let's wait to make a real feedback...
i'm using taskkiller because of some programs like "Quick System Info" ver 1.4.5. I can't find any other way to close this app. I can remove icons from notification bar. but app is still running. Any ideas for that ?
On standby for 9 hours i'm getting 30% less battery.
Is android 2.1 supposed to use less battery anyway ? seriously considering going back to 1.6
Mine has been running for 20 hours now since fully charged and still has 54% of the battery. This is with 2h 15mins out of standby watching Youtube videos and talking on the phone.
Wifi is always on, Bluetooth is also always on. And yes, 2.1 does better battery conservancy for me: with 1.6 sometimes the phone wouldn't go into standby thus killing e.g. 30% of the battery over night doing nothing. I haven't noticed anything similar since I upgraded to 2.1.
I only use advanced task killer rarely if I want to kill a running process. No auto-kills...
P.S. Also I only use 2G.
Skype also eats a lot of battery. i cant find a way to turn it off other than with a task killer
O skype, if you go to 3rt. tab (I think its "My info".. My system is not in english) menu button will show an opt to disconnect, that completly leave app.
its fine to use task killer, JUST end tasks yourself with the end all button.
CERTAINLY dont put auto-kill processes or ur battery will die, hope it helps.
I know this has probably been asked hundreds of times and I have searched up and down the forums but have found no fix for my battery problem.
I always have my battery at the dimmest level. Mostly only text, the occasional 5 min phone call and web browse here and there. Yet when i look into the battery use the display is always at atleast 96% ive never seen it less than that. But i kno that it has to be something other than just the display though.
I stoped using beautiful widgets, and froze media hub (i read that it eats battery in the bg) recently ive been monotoring my system through system panel.
As of now system panel tells me that System Processes is at 5.7% and system at 2.6% The next highest thing is Swype at 0.4% and android.process.acore at 0.2% the rest of the things are at 0.0%
I was thinking that it might be the battery or just the phone itself...
Edit: im sorry idk why the app didnt post all my post <=(

Having your screen use that much (as a percent) isn't necessarily a bad thing. It means that everything else is using minimal power. You also shouldn't be checking your stats for useful info within moments of turning it on. Give it a whole day of use and check again. Your screen will have used less % after a day but it is totally normal for it to be the largest user of power.
So then what could be causing the battery drain?

How much drain?
You should expect to get 4-5 hours of use from your Vibrant. Total time could range from four hours to several days, which is what you hear people saying in most battery threads. What they often don't state is how much time the phone is actually in use and whether you get 5 hours or 24 hours before you hit 0% battery you probably are using the phone (screen on for anything, or screen off while listening to music or talking.) for 4-5 hours.
So is your phone getting less use then that? If so then you may have some other issue.

The links are very informative
Of actual use, not just standy by I get just about 4 hours. Usually under 4.
And that link looks pretty interesting

Fast Battery Drain
Bad News Everyone!
I have spent the last 3 days searching here and other forums trying to find out why my battery has been horrible. My battery goes to around 30% after only 3 or 4 hours of very slight use (2 or 3 texts and checking email once).
I have done two complete battery drain to full charge with the phone off the past two days to try and get a better reading.
The history of the drain, at the end of November I rooted and installed RyanZA OCLF, rooted, and lag fixed, no issues. Installed the basics of rooted (busybox, superuser) and SetCPU.
SetCPU presented problems with not coming out of sleep and freezing after reboots. The battery would give about 6 hours of moderate use. I played around with settings, but ultimately removed it and when I did my battery was lasting 3 hours longer with moderate use, facebook, twitter, browser, 20-30 mins of gaming. From 12:00 pm (leaving work) to 9:00 at night (leaving school) with 35-40% left before I got home.
About 4 days ago, my battery was draining very quickly. Wake up, unplug phone at fully charged, get ready for work, grab phone to leave for work and I am down to 90% after only 20 minutes of standby. When it use to have it around 96% by the time I got to work, about an hour with light use. Seeing this problem I went back and looked at updates and apps that I had. The only thing I could think was Launcher Pro, but no one else has reported battery drain issues and it wasnt showing in Battery Info.
In my attempts, I have done the following.
Went from 7 to 3 screens (one widget per screen)
Removed apps and bloatware with Titanium Backup
Doubled checked my account syncs, Facebook once a day, no twitter sync,
Screen brightness at ZERO
2 Battery Resets (fully drained to recharge phone off)
Installed Watchdog to find any heavy mem/cpu users, (none found)
And a crap-load of googling, forum searching (here and cyanogen forums), and I am still getting horrible battery life.
Today for example: Phone completey charged 10:30 am with only 3 texts sent and I am currently at 28% at 3:15. 5 hours of stand-by should not have drained that much battery. No GPS on.
If you have any ideas of what it could be, at this point I have alread bought a new battery, I would love to hear back.
edit: I am running stock rom 2.1-update1
I used to have poor battery life as well on stock 2.1 rom until i flashed the leaked jk6 update. Im now averaging about 25 hrs per charge with my phone pretty much always in use whether its calls, texting, music, gaming, web, movies ect...
Not to mention i also get 3g in places i havent before and faster DLs, less lag... This rom is awesome, i suggest giving it a try..

dubbz106, thanks for the advice. I have not had a huge desire to flash a new rom because my phone had performed pretty good. But with my G1 I was keeping it alive through cyanogenmods.
I have been moving closer to flashing and this new battery issue my push me to do it.
Can you link the thread for the rom?
Hi,
For those of you that have Battery Monitor Widget installed, what kind of average usage are you seeing with the phone idle, screen off?
On my old Desire it'd sit at something around low double digits, 10mA or so idle with the screen off...
On my new shiny SGSII it's at about 180mA odd, which may explain why I struggle to get a days usage out of it. I've tried different ROMs (stock rooted, lite'ning, currently on villain 2.4.2) and different modems (currently KG6) and have used Ti to freeze all of the samsung bloatware without any improvement...
What kinds of values are others seeing?
Thanks
Jon
in idle , i get average of 50-60mA .. but after 3,4 hours of idle , i can get it as low as 9-10mA .. running on sensation rom 1.4 .. in normal use , it will hike from 100+ma to 400mA ..
it's actually a bit higher than my last desire HD. which in idle can get as low as 4-5 mA .. i guess that's all depend on the kernel ..
seeing at your idle usage about 180mA, that's definitely have something wrong somewhere. gotta find what apps draining the battery
Just did a test while I was down the gym - with mobile data off, but streaming music to a bluetooth headset, it was down to 60-80mA. Turn it back on and it's gone back up again...
Gtalk is frozen, Latitude isn't signed in... Nothing obvious shows up in Better Battyer Stats.. Other than removing apps one by one, any bright ideas as to how to work out which is the culprit?
I think i read that HTC phones actuality give true mah battery rates where on the S2 it is only get`s estimated.
I fully charged it last night, and left it alone overnight. Perfect signal (local picocell about 10 ft away), pretty much everything disabled, all user apps, samsung stuff frozen - only google apps unfrozen. Background data disabled, bluetooth, gps, wifi off.
After a few minutes, after a short while at 60mA odd it sat idling at about 9mA pretty much all night - used about 8% overnight. I re-enabled background sync, now sat on my desk at work with a reasonable 3G signal it's sat at about 60mA.
Time to start unfreezing apps and see what's draining it!

It's installed - I get a lot of events/0 and suspend listed in process, and not that many wakelocks listed...
I've just frozen the samsung email client (exchange) and the associated processes, and my usage has dropped from 60-100mA at idle to under 20 - looks like this may be the culprit!
Going to try unfreezing it and seeing if it goes back up again...
I gave up trying to freeze / unfreeze stuff - too much hassle.
So - did a factory reset this morning, so back to a totally fresh villain install. I even removed my 32G sd card in case that was causing issues..
Disabled automatic app re-installing, and have been slowly setting things back up while watching the juice usage.
Currently with touchwiz and all of the samsung crap frozen, no widgets running, my 2 gmail accounts and exchange activesync configured, and it's idling at about 50-60mA.
It's going to be a pretty drawn out process working out what's causing the drain
Update and FIX!
My phone is no longer draining massive amount of batt life when idle (3-5% after 7 hours of idle), android system usage is now down to 5-15% instead of 78-97% from before.
My fixes.
1. Turn off data syncing
2. Turn off wifi while on the road (so wifi doesn't constantly look for signals).
3. Clear memory
Yes, att installs a lot of bloatware that constantly update for changes.
If killing those services AND disabling data syncing doesn't help your problem, then you have a kernel problem (like myself).
If this is the case, do the following:
1. Take phone back to att and get a replacement
OR
2. Re-flash your android with the STOCK kernel found here
http://forum.xda-developers.com/showthread.php?t=1286432
OR
3. Reflash with cognition x2 (reported to solve a member's problem, I didn't try this myself).
NOTE** This will root your phone, you will NOT get the exclamation mark during boot up, but kernel counter may be at "1" after this process.
Re-flashing my phone AND applying the three tricks I mentioned above worked for me..finally my phone is no longer crippled with crappy battery life and recharging is A LOT faster now.
I must be going crazy but this sg2 is killing me. I got it from Att yesterday and the battery life has been pretty HORRIBLE. (First time android user btw).
The phone will eat up 10% of my batter life after only 90 mins of idle. I checked the battery usage and Android OS is at around 78%!!! How do I fix this problem? I downloaded OS monitor and didn't really see anything that uses a lot of CPU, except for certain files syncing from time to time (but 2-3% usage usually).
Checked with battery spy and apparently the majority of the time, the phone was hovering around 200mhz 70% of the time and not deep sleep.
It's sad to have only 1.5 hours of display time with a battery of 45% left (7 hours total time)...coming from an Iphone 3gs, this is just unacceptable. I almost flashed to the 2.3.5 firmware but noticed it's NOT compatible with ATT's version of SG2.
I see people who have a total time of 2 days AND a screen time with 3 hours with 30% battery left. I wish I can get half that!
Running on 2.3.4, can't be the infamous drainage bug right? Thought that only happens with the 2.3.3s
Wifi on, application sync on, GPS off, brightness at 25%, using live wallpaper (the windmill). No active apps on. Downloaded aim, epocrates, battery monitor, cpu spy, and os monitor..rest of the apps are stock.
Update
According to my CPU spy
For the past hour that the phone was in idle
2:20mins at 1200mhz
4:52mins at 1000mhz
8:33 at 800mhz
1:28 at 500mhz
10:11 at 200mhz
33:36 in deep sleep
Currently Android CPU usage is @ 97%, display time of 7mins(2%)
2h 30mins since last charge (97% charge)..current power is 79%. Did nothing but idling and checking battery life.
So...that's 30 mins out of the hour in which my idling cellphone was hacking the pentagon....
Also the cellphone is a tiny bit warm to the touch (not cold)
I have 35% battery life remaining and have been unplugged for nearly 11 hours. This is significantly better than what I was getting with a Thunderbolt on Verizon, where I was needing to charge after about six hours of use. 11 hours and 35% remaining isn't the best in the world, but it's only been two days. The phone needs a few days to charge and discharge to determine true battery stats and will probably get better.
Being that this is your first Android battery life will not seem great but let it settle in for a few days it should get better.

If you only got the phone yesterday, its way to early to make any judgments on battery life. Battery needs at least 3-5 days to settle in and build consistent battery stats.
Also, what are you settings? Auto Brightness, Bluetooth, GPS, auto syn(exchange emal, gmail, facebook, etc). If your not using these, they should be OFF. It's easy to manually refresh email, etc.
I've seen some people reporting very high Android OS(over 50%) but still getting solid battery life.
I'm at 1hr display time, heavy texting. 72% left, been unplugged for 12hrs
no people what this guy is talking about is the android os bug. i have it too. hopefully an upgrade or different rom will fix it. my phone has been unplugged 11 hours with only 1 1/2 hour display but android os has ran for 52 minutes and now im at 32% battery life. once this bug gets worked out the battery life will be amazing.
I don't think that there is an android OS bug. My android OS shows as being 42% with 13hrs of moderate use and I am still at 67% battery remaining. This is by far the best battery use I have ever experienced on an android device! My cappy would not even come close to this performance and this is on stock ROM and kernel.

I'm very happy with mine, this was the first total drain on a new battery so I know it will only get better.
Total time: 18hr 25min
Display time: 4hr 48min
I think it's the system os, not the hardware. There were a few times when the battery didn't discharge itself at 7%/hour (had it idle for 3 hours and it went down like 2%).
And yes, everything is turned off except the sync app data and wifi. There's no option to turn off 4g btw. It's just weird how sometimes it's in this mode of power drainage, and then sometimes it doesn't drain much..but most of the time, it's draining.
I seriously doubt the phone can only run 2.5 hours worth of heavy usage or 12 hours of standby (it should last days!). If this is "normal" for android, then maybe I should have a visit back to att and exchange for an iphone (and I really don't to!)

I agree - as I said in the Android OS drain thread, even in "good" situations, Android OS displays way high on our systems. I think it's a reporting bug.
I dropped 2% in 5.5 hours completely idle (sitting on my shelf) last night - Android OS was at over 60%. It seems that so far for me, the higher it is, the better my battery life is.
I drop around 15-20% in 9 hours of being mostly idle at my desk at work - it's a weak-signal location so the radio eats much more battery.
One thing is that unlike first-generation GalaxyS devices and interim ones like the Infuse, the GS2 has a coulomb-counter type of battery gauge. This type of gauge sometimes needs to be calibrated with multiple charge/discharge cycles or it will misreport battery state of charge. (However, when calibrated, it's much more accurate.)
Edit: I do have some power management tweaks in the kernel I'm running, but they don't make that much off a difference except in some high-drain corner cases in my experience. I'll be releasing it sometime later this week depending on how well these antibiotics do their job.
Do i need to install a battery app to see the percentage? or we have a way?

If you see "DataTracker-FD" or "Fast Dormancy" as the top wake lock, go into dialer
dial *#*#9900#*#*
disable Fast Dormancy (FD).
By default, the Samsung Galaxy S II has Fast Dormancy support enabled. One of the goals of Fast Dormancy is to increase the battery life of a device, by limiting the amount of signaling between the phone and the cell network. But, when Fast Dormancy it is not enabled in the network and is enabled on the phone it ironically works the other way around, and actually drains more battery than before.

That applies to the I9100.
As far as I can tell, the I777 has FD disabled by default. (This may change once I9100 ROM ports start showing up)
Okay, charged my battery to 97%(I got a beep saying it's fully charged). Idled for the past 2 hours and 22 mins. Battery is at 86%.
According to the battery, my screen account for 2%, and the android system accounts for 97%.
This is a stock phone guys, I have no apps installed!

Just search up "battery indicator" in the Market and you'll get a few to choose from.
I too got mine yesterday and started tinkering around with installing apps and such to test out all functions before I rooted it and move onto cm7 most likely. The 1 things I noticed was that the battery was NOT completely full when it was first turned on at the store so once it got a little lower after playing with it I charged it up overnight. Today the battery was WAY BETTER and was not dead yet. I have been using it NON STOP today, rebooting it, testing it, trying to root it, rebooting some more, some time using tango to test it out, watched a Netflix movie, pretty much taking full advantage of it all day. I finally decided to charge it up and use my Captivate a bit. I didn't keep track of usage and times today but I KNOW it lasted a WAY LONGER time with all I was doing with it than my Cappy. Tomorrow I will check more out possibly before putting on a rom.
So LOOOONNNNGGGG STORY short make sure you charge it up once you get it before messing with it too much and then it will LAST LONGER.

After two nights of completely draining then recharging the battery to full, the battery has gotten significantly better. I'm trying to drain it again before I go to bed tonight but I don't think I'll make it.
I played the entirety of Toy Story 3 on max brightness, and only burned 20% of the battery!
I'm not very happy with the battery life so far. Some website had tips on getting more battery life and one of them was to turn the screen brightness all the way down. That's way too dark. I keep it a little less than half.
I always have it 100% charge before I go to work. I normally work 8:30-5:00, but today we had some snow and went in at 11AM. So, today we skipped taking our morning tea/coffee break, which I'd normally be using my phone on. The only thing different about my morning is that I used the alarm clock 2 more times than normal.
All I did so far was listen to 3, maybe 4 videos on YouTube on my drive to work through bluetooth, check a few notifications, and my lunch break I updated every app that said it had an update.
I'm down to 45% already!
If I go into battery to see what is using my battery, everything in there only adds up to 20%.. so 45% I have left + 20% I just mentioned = 65%.. where did the other 35% go?
Screen 7%, Mediaserver 3%, YouTube 2%, Android OS 1%, Android System 1%, Phone Idle 1%, Google Play Store 1%, Google Services 1%, Cell Standby 1%, Wi-Fi 1%, Chrome 1%.
I've got hardly anything installed since I just got the phone. Haven't even rooted it yet. Only have about 4 apps installed, which I mostly don't use yet.
Nope best battery life for me. Up to 6hrs sot
Yes - the battery life is atrocious - despite doze. Greenify with aggressive doze does better. Some times nothing kicks in and the phone shows a straight line of battery death. I am no talking rooting and beyond - I am talking straight as it is.
