I have seen very conflicting reports about battery life when running Android. Some claim they have battery life as good as WinMo (1-2% drain/hr standby) and others claim anywhere from 5-8% drain in standby/hr.
I don't really think there is a difference between builds because I see claims of good and bad battery life for basically all builds.
To straighten this out I thought I would start a poll - please tell me what kind of standby drain/hr you are getting.
no response so far since it is just a poll and we are moving off the first page - BUMP

Need to add selection to see which build people are using also as well as battery life. That way we can have a better idea which build(s) offer best battery life.

I tried two Android ROMs a while ago - shubcraft (I think 1.2b) and Darkstone's Sense.
Shubcraft DEFINITELY had much lower consumption than darkstone's ROM, both in standby and in use.
It's just a shame the shubcraft ROM is so ugly.
With shub 1.3 and mattc's sense build I get less than 1% drain in standby. Shub 1.4 burned slightly over 1%. When I'm in standby everything is off except the phone radio. I also don't use any task killers.
Still not as good as winmo though. I only use 1% every 3 hours on standby in winmo.
Why do you consider shubcraft ugly? Because it doesn't have sense? I love the performance and look of the shubcraft cyanogen rom 1.4b. I get battery life very close to my WM energy rom.
I have a
TMOUS HD2 with 2.09 radio in NYC,
Chucky Android rom and Darkstone V2.1.
It drain >7%/hour for standby.
Can someone tell me how they get <1% per hour battery lose with which build, device and etc? I really like to try that out sometime.
Its a bit more then 1% per hour on shubcraft 1.4, but i use SetCpu.
shubcraft 1.4 @ 925mV r4 KERNEL, setcpu conservative minimum on standby, sdcard powermanagement tweaks, all tasks killed, VBN beta 5 Android Rom, 2.12.50_2 Radio ~ 3% / 5h

Only difference is I am running Energy ROM, but the rest is the same.. I've been using WM due to the poor battery life, as I can't make it through the day in Android.
Solution for 5%/h drain standby problem
I had 5%/h battery drain in StandBy, but I believe I found the solution (it is working for me).
(a "small" copy of my another post)
Solution (need confimation), found somewhere on xda-forum
1. Battery calibration (not sure if this task was really necessery)
2. Charge battery to fulll (green led light expected)
- on WinMo till green led, turn off the phone (shutdown winmo)
- on phone turned off (till green led)
3. boot WinMo and Android
- then remove /data/system/batterystats.bin
Use this commands from Android Terminal (free).
su
rm /data/system/batterystats.bin
Click to expand...
Click to collapse
3. Restart Android
- in that moment I had expected 1%/h drain already
- use battery till it become almost (~10%) empty (just use the phone as usualy).
Thats all.
Propably, after many android switches (new distribution tests) the battery stats was broken - collected partially in different Android instances (on memory card).
Then finally, after 1 week with 5%/h battery drain problem in standby I have 1%/h in standby again.
I think it is standard drain in haret.exe version.
I've seen many people saying they have poor battery life, see now with no changes in windows mobile or android such as using set cpu I get just over 1% per hour. I was asleep for nine hours with my phone in stand by mode with the radio on and I lost ten percent. In the same conditions with windows mobile I'd usually of lost about six percent so there is still quite a large difference. however I am using froyostone version one as my daily os and its manageable, listening to music and using 3g rather frequently and it lasts me the day.
So for me battery life isn't a major problem
Based on the broad range of battery drainage reports (at least ten percent in each category) the problem could be with battery calibration like in lemars post. I am going to try his recmmendation tonight and report back.

With a few calls, wireless and autosync on at all time, my battery drops down from 100% to about 80% in 5hrs usage.
data on GSM during standby instead of 3G..
unless i need to surf net or use data intensive stuff, or else for facebook and twitter updates, i remain in GSM data as well as for push mail notifications..
my battery lost is less then 1% while on standby partly because i use setcpu for clock speed setting.. another reason is possibly due to my GSM signal on Max at -60dBm so i use less energy to lock on to the signal..

There are many free terminals like this http://www.androlib.com/android.application.jackpal-androidterm-zxnC.aspx.
Install from Market and on the Android prompt "#" put su<Enter>rm /data/system/batterystats.bin<Enter>exit<Enter>exit<Enter>.
There will be no message after rm command - if there is one, you missed something.
I can confirm that after more then one day of usage I still have ~1%/h in standby. So this solved my problems.

Yes... none of the 2.1 ROMs currently provide long battery life times. I believe that one of the chefs said it was because of the kernel and that it won't be fixed until HTC releases or leaks an official Hero kernel for Android 2.1.
However it also depends on what you think would be a good/adequate battery life.
Personally I charge every night so as long as the phone lasts circa 24 hours it is fine with me.
All 1.5 based roms should give you battery life over 24 hours even with everything turned on.
as for tips:
-turn of wifi when not using it
-turn of mobile internet when not using it
-turn of gps
-always put phone in sleep mode (end button) when not using it
- screen time out turned low
- backlight on low
- kill tasks that run in background
- don't have a bright wallpaper
Just depends how extreme you want to go
I have a decent battery life on the rom I am on (see sig) and I use a brightish wallpaper and auto backlight but always turn wifi off when out of the house.
Flashing a new radio file can also help battery life.
Edit: with a bit of use I have lost 5% in the last 8 hours on my phone today
Mhm too bad i like to use 2.1
Does 2.1 Roms drain the battery so much more?
Battery life is very important for me...
I am running the original Rom and i had to charge my hero every night, too.
But one day is okay...
Thank you for your tipps (bright wallpapers *lol*, but it make sense^^)
So what are you fav. 1.5 roms?

P.s. Does HTC want to upgrade the hero to 2.1 ??? Would be awesome...any dates?

SenseHero 1.6 is awesome 1.5 ROM
Also it uses a nice theme, and can last for more than a day

To me BeHero has the best battery life of the 2.1 roms and Villain had the worst (the life would literally go from 100% to 50% in 4hrs and I barely touched the phone).

I put on 3.4 yesterday and ya my battery life was terrible. The only thing is that I hadn't ever updated my radio. Now instead of it being dead within 4-5 hours I've gone over a dozen and my battery is down to 45%, which is pretty good for me. I'm a pretty data intensive with my phone.
if you want to test the battery life, test it 2 days or more!, because the first day every rom(almost..) is draining fast, because then it needs to set up everything etc(idk excactly why)

Wow I find it very hard to believe that you only lost 5% battery in the last 8 hours with little use...do you have mobile data on or off?
Even with no use at all I can never get 5% decrease in 8 hours, regardless of whether its a 1.5 or 2.1 ROM. I keep my mobile data on all day and night and with no use at all i lose like 20% battery life in 4 hours.
If you want 2.1 firmware with good battery life, go foe BeHero_v1.3.2, I am using it without any trouble!

Trust me I was not lying I have no reason too.
Will report on what it does today.
Yesterday I had mobile internet mainly off but turned it off at certain times of the day.
So far today (3 hours since fully charged)
-wifi for about an hour
-use wifi things during that time (seesmic and News Rob mainly)
- bluetooth for 45 mins (journey to work)
- mobile internet for about 40 mins
- downloaded an app and tested it (used barcode scanner to scan a barcode (twice) and go to the download link)
- synced emails
- sent a text
- mobile internet now off and back asleep
And a reboot as my connection was lost for some strange reason
lost 2%

i can only say that perhaps ur battery is a special one..
i cant even get half of that with 1.5 rom (with the same usage)..i will surely lost like 10% with that kinda usage on phone..
no offense..but..unbelievable...
my current setting :
GPS , WIFI & Bluetooth off..
brightness around 15%
dark wallpaper..
mobile internet on when browsing needed
@aziz831
Lennyuk´s battery consumption is real. My battery would last 216 hours just in idle. But that would mean just asleep and waiting for a call.
I use WiFi 18/7, I have in that time mobile data enabled, I have a brown wallpaper and my backlight is on lowest level (but I can still see everything). My average loss is 1-1,5 % a hour if I´m in idle with all this enabled. Over night I do disable WiFi and auto sync, that saves a lot of power.
My average time of usage with one load is about 80-96 hours.
Just wondering because right now I'm using GSB v2.6 and I'm getting max 6 hours of battery life through normal use like checking email, sms, casual browsing, and listening to music.

Have you tried re-calibrating your battery? Made a huge difference for me; it's good to do especially with a lot of ROM flashing, but even with just one it can throw your battery calculations off.
FYI follow the instructions to the letter, otherwise you might as well not do it at all IMHO.
I had the same issue using GSB 2.X. Switched to OMGB 1.1.1 and i now get 15 hours with moderate usage and no tweaks.

I've gotten over 30 hours before with GSB, immediately after a recalibration.
Your best bet for battery life is setcpu settings. As long as you're using froyo and gingerbread you'll get a boost.
I suggest Tazz as his ROM's have always worked for me. My setcpu sleep profile is:
min 19mhz
max: 480mhz
governer: smartass
and in advanced settings I have:
polling interval: default
Whatever the next one is: 98
Ignore smart or hwatever the third one is: 1
bias: 4
edit: With this I can get a good day or two of moderate use.
I found on GSB that that 19mhz is too low and the phone does not always wake from sleep. I followed workshed's suggestion of min 480 mhz with max 710 using CM7's CPU settings and all worked very well...that is until 2.0 when battery life went to hell. I recalibrated but i think the problem was my exchange mail app.
Oh, and with smartass you shouldn't have to set sleep profiles. Supposedly it's "smart" enough to figure that out
You can also try collins battery tweak, I use it on tazz gingerbread and it works awesome my phone used to die pretty fast before I tried it and now that I put it back on my phone I am very glad I did.
Im running GSB 2.8 but for me, all seems to be going well.
In one day, off a single charge, I've gone 12-14 hours at a time!
Make sure you always charge correctly, and don't abuse the phone's battery all the time!
Been trying out various ROMs and lately, I've settled on FroShedYo's Final V11 with CM6.1 as my everyday workhorse, stability over speed, and with a bit of battery calibration - getting an average of easily 20 to 30 hours off a full charge on OEM 1500 maH battery originally for the HTC Ozone (so it's about 15% higher capacity than stock's 1300 maH, which I keep as a spare/backup.)
With a bit of tweaking on CPU clocking (Ondemand), turning off vibrate & alert sounds/LED's, and email checks every 60 minutes (1 account only + Gmail pushed) and minimal widgets open, etc. - I can leave the house at the beginning of a long day, go about daily business, voice calls, check email checks, quick news & weather update, etc. and still have 25% to 50% battery life after an extended 12 to 15 hours day on the move, depending on how the device is used. I get a poor 3G signal at the house flipping to 1X often & back, and wifi OFF on the road (BlueTooth ON for driving but no Maps/NAV (ON at home.) In short, plenty of variables on how the battery is getting drained - in standby mode, clock speed is lowered so I could still be over 90 to 95% battery after 2 years but it will slide downward with active usage. After wiping/flashing & reinstalling all the APPS & fine-tuning the settings, I do a NAND backup and then do the battery calibration - and after 1 full cycle, I've been consistently getting these standby & usage time - which I can live with (C2C flashed and extra goodies on a 16GB SD card.) Yesterday, it was showing over 50% after 15 hours of light/moderate usage.
I've tried the latest nearly finalized GSB/GB Roms & variants, they are faster & fancier, but FC's, GPS issues & other minor bugs plus "not as good" battery life had pushed it back to 2.2 OS on the Eris. OMGB 1.1.1.1 and the Condemned CM7 just out this week are pretty cool - but battery life really slide quickly - unlikely to see more than 10 to 15 hours of usage out of a standard/non-extended battery.
The other one that I like is the Nonsensikal 2.2.1 ROM, troublefree, stable & reliable - the edge on battery yielding to FroShedYo's version ( keep that on another 8GB card along with the newest GB releases for "playing")
Otherwise, the xtrSENSES 5.x and xtrROM 5.x are fine as well for everyday use - performance & battery life-wise over the latest stock 2.1 ROM.
Those are my two cents for what it's worth, great work being done here and it's giving new life to the Eris, not quite EOL for some of us - played with the TB in the store, nice big screen & fast, but I'm not about to wear a "brick" phone going out on the job with an extended/bulky battery just for bragging about 4G/LTE. Mobile devices have come a long way, I still got my original analog MicroTac XLT with a 2200 maH tipping the scale at 10 oz in my bottom storage drawer.
On the sideline for a "polished" GB/GSB ROM with the bugs resolved and better battery life, and I'm off to flashing it on my spare SD to test it out. for the "adoption" usage.

6 hours wow thats bad man. i get 30+ running gingertazz
i leave 3g off till i need it and usally just use wifi if around wifi spot
do a recal. like people suggested
so since i installed this new ROM CM7 I have noticed my battery usage is not so great when i look at the after 2 hours of use cell standby is 32% and phone idle is 24% android system 21% before it was always android system at the top so it just seems excessive use for phone idle and standby im not a expert tho any ideas???
well bro u can this
1. turn off wifi & data
2. use task killer to end tasks wen nt using phne
3. turn off auto synchronization
4. lower cpu freq
cm7 is not official so hv to face such prblms!!
yea i already do all that but oh well ill ust wait for the official release i actually like the ROM
67% ->goto bed->after 9hrs->still at 67% on stock v10f rooted
Im using CM7 too, and I've noticed that MAYBE there is a problem with wifi... Battery consumption is relatively normal, except for when the wifi is on, then it uses around 1% each 4-5 minutes, but with the phone idling all night it will use 2 or 3 %
Make sure you stop maps and music app after you use those
CM7 does have battery problems. You can try putting francisco's tweaks along with his sql patch. Will give you some kind of slight increase in battery performance.
You can use the calibration of the battery.
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.
Sent from my SAMSUNG-SGH-I777 using xda premium
Used Nexus S, LG Thrill, Samsung Focus, Infuse, This is the best Android phone for battery. I have 40% left with normal use (emails, calls, music, read news) at the end of the day. Huraaaaa

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?
Install this app:

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!

I'm talking about live battery display. I installed no lock and have no lock screen to see how many % left.

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!
How you guys get even 2 days of battery??
I am tired of tryin gall the combinations of settings / kernel / ROMS nothing has helped till date.
I am not able to get battery for a complete day. Freaking it drains it off in 9-10 hours.
There are users who are getting 2 days of battery with wifi/edge on at all the time, with overclocked phone, and many other options enabled. But I am not getting any of these.
My usage includes
* 1-2 hrs of music
* 1-2 hrs of edge
* frequent texting but can be summarized for 1 hr in a day.
* hardly 10-30 mins of calls
* 10-30mins of games
CyanogenMatt 1.1
franco kernel 19.4 gbs v18cfs
InteractiveX 480-600 mhz
all this is normal and way below average usage but still I am not able to get battery life. I hate recharging the phone after every few hours. Have searched forums tried suggestion but nothing worked.
Maybe I am choosing wrong combination of ROM / kernel , I have gone complete clueless now, any help or suggestion is welcome.

It is because of usage patterns. Based on your usage, I think its normally for your battery to drain just like that.

Thanks for replying terratrix,
but users are using continuous wi-fi and get a complete day of battery, I dont even use that. AFAIK wi-fi uses more battery than EDGE. Can you suggest me proper ROM+kernel combination?
I installed cyanogenmatt 1.1 thinking it would improve battery life but it didnt.

Well theta because they are using the phone less often. You are wrong , wifi consumes far less battery than edge. Wifi on standby drains minimal battery.

It's mostly about background tasks. Install supercharger and a task killer to kill your tasks on screen off. Then disable unneeded autostarting applications with Gemini or Autostarts. This way I get about 1% battery for 4 hours without using my phone. And I strongly advice you to use 480/YourMaxStable with SmartassV2 as Smartass automatically manages the current CPU frequency. Your brightness should be between 25 and 50%. And also disable any unused at the moment radio (including mobile data).
how would I disable radio?
do you mean not using radio is disable it??
Well here's how my phone goes on for 2 days
android assistant app for cleaning memory every 10 minutes and for killing apps on startup
Advanced task killer for killing tasks(set on auto kill)
Antutu power saver which has some good features(puts phone on flight mode at night for few hours)
or use juice defender(has extra features)
try keeping edge/3g/wi-fi/bluetooth/gps off when not using(saves a lot of battery)
reduced brightness(40-50%)
and keep screen off when not in use
also keep OC freq at 729/480 its the best know OC for our phone performance and battery wise
and InteractiveX is well know for battery saving
(i prefer on-demand because of performance and gaming )
the above things help me use my phone for 2 days or i must say 1&1/2 day
with 4-5 hours gaming(3d HD games)
1-2hours browsing the net
few messages and calls here and there
on a full charge and normal usage at the end of the day i have phone battery at 40-50%
A radio is basically a wireless I/O device. GPS, Bluetooth, Baseband, WiFi, FM... - these are different types of radios. They drain power when powered on so if you want battery life you should simply disable the ones that you aren't using at the moment.
@viv_jen: There is no need to autokill every 10 minutes if you don't have unneeded autostart applications. Task managers also drain battery if used too often. It's also a good idea to use the long-press back key feature of CyanogenMod (It kills the currently visible task).
To pitch in my 2 cents worth,
I've found wifi uses quite a bit less than edge/3g data on this particular phone.
This phone has shocking battery life, even for a smartphone.
What you are getting seems about normal for your usage. My battery will be between 20 and 30% after 4 hours of music and 3g browsing. Once I stop doing these things it goes down at about 2% an hour on wifi, about 3% an hour on 2g, and 5% an hour on 3g. I ended up keeping my charge cable on me when I go places and actively use the phone, and "topping up" the battery when I'm sitting at a desk or whatever.
thank you guys for valuable inputs,
could the combination of ROM + kernel also help?
I tried cyanogenmatt + goldenleaf after some of the user suggested that it gives enough battery.
I also heard void gives a good battery.

yep it does
for me atleast
@nogav: WiFi drain depends mostly on Tx (Transmit) power. Mostly we receive information from the internet (Which means Rx is way more important than Tx), so after running a few speed tests (Speedtest.net app) at each option avaliable at the Wifi Tx Power app from market I found out that internet speed at a Tx power of 4dBm is roughtly the same as for 32dBm. Also, our device only supports 801.11b/g mode, so internet speed isn't the best thing about Optimus One (Excluding HDSPA).
@droidevil: The thing that drains most battery is Stagefright. It is able to play 520p mp4 videos almost smoothly, but it is a battery killer. Hardware acceleration also increases performance at the cost of battery, but it is reasonably balanced. Other things that depend on roms: number of preinstalled apps. Deodexed apps load faster, and the less of them there are, the faster the phone boots and runs. If you have about 100-200 programs installed, Autostarts, Advanced Task Killer and Supercharger are likely to be used.
thank you guys for your useful information..
Just raised all urs thanks meter for helping me out..
Well I have installed android assistant set to auto kill on every 10 mins.
Installed gemini and stopped the apps which are set to open on boot.
brightness is the minimum
480-728mhz with InteractiveX
so far 12 hours have passed by and have 50% left
Normal texting, gprs browsing, music no games though.
Lets see how far can I pull it off.

Nonono, don't use autokill, they are just crap, not needed, they drain more battery.
I have installed void forever to see whether it helps in battery performance.
The ROM itself is very fast, just wondering which kernel will best suit the rom to give the desired battery performance.
Any suggestions please..!!!!!
My LG optimus v running iho cm7 only gets about two hours of battery through normal use.

franco
and use interactiveX governor(if you want for battery)
franco's CFS / BFS?
I have read around that fserve's kernel also gives good battery...
IMHO, actually your battery drain is actually pretty good for a usage like that, I am using more or less the usage of yours and everyday I have to charge.
