Try this:
top -d 240
and leave it alone for at least 4 minutes.
Then look at the CPU % column and you can see what is using CPU time. Ideally everything should be 0%. Less than 1% might be ok.
or install one of the battery graph programs. I've used "BatteryGraph" to monitor what uses up the battery.
I have tried and the CPU is 8% usr is 2.3% nice 90% and idle 0.7% and rest of them are 0. any advice

My battery drains empty in about 12 hours now without using it, it's just 12 hours of standby
Anyone able to see the problem ??Code:Powertop 1.13.3 Sleeping for 11 seconds before sampling Collecting data for 600 seconds Sample interval was 10m 00s 19287us C# | Ratio | Avg/dura | Frequency | Ratio --------+--------+----------+-----------+--------+ C0 | 7.9% | | 1150 MHz | nan% | C1 | 0.6% | 3.8ms | C2 | 10.4% | 6.8ms | C3 | 48.7% | 110.5ms | C4 | 32.4% | 631.0ms | ....

But I more mean to look at the part below so you can see what is using your CPU cycles:
for me its:
skyhost at 1.4% CPU,
telepathy-spirit 0.2% CPU
These are part of the instant message protocols I have.
I Mainly suggest top so it's easy to identify the culprit programs and doesn't involve installing things. But powertop does let you see the power states which is nice.

The i2c irq count looks very high, but all these figures might be a bit polluted since it kinda looks like your device wasn't idle the entire powertop sampling period
The powertop application was runnig for 10 minutes and I left the device on a table for at least 15 minutes so any activity was not done by me.
I have increased the battery life a bit now. The last week my phone was running at 850 Mhz max (not a problem) but the low end was 125 (a problem I guess). Now the limits are 250 till 850 and battery life increased by something like 25%

Mine drops dead in about 4-5 hours...but I'm a heavy user of the device. Constantly using it all day for just about everything. Pedometer, GPS nav, music, podcasts, streaming audio, FM transmitter in the car, photos/movies, Web browsing, games, etc..etc..etc..and more.

You can redirect powertop's output to the text file and then copy+paste it for examination here. like this:
# powertop > /home/user/MyDocs/tmp/powertop-out.txt

3g starts to win once you're doing something that takes more than 5-10 seconds of continuous transfer at max 3g speed to complete. Lots of websites are so slow to respond that they load about as fast on 2g and 3g, in which case 2g would use less power to do it.
Downloading podcasts with gpodder is a case where 3g clearly uses less power than 2g.
