Maybe you should reset your cpu back to default (1 GHz), overclock always drain battery.

So I've just recently rooted my Incredible (about 4 months now) and I bought a 3500 mAh battery off ebay for about 12 dollars around the same time. I used to get really great battery life with it. About 2 full days without having to charge. I'm not sure if the battery's getting worse or if this is normal battery depletion for all you other Incredible users.
I'm running CM7 nightly 258, the latest one, and have the newest Incredikernel, just flashed the kernel about a week ago. I'm still pretty new to the rooting game. Before I flashed the kernel I just had the normal kernel for CM7. I was getting about 10 hours of battery before and tried the battery calibration, but I think I did it wrong and got maybe 8 after that.
So I tried running the Incredikernel and was getting between 12-20 hours of battery life after that. My usage is at least 2 hours of Pandora a day using 3g, sometimes 3-4 hours. Moderate to high internet usage, rarely make calls, and moderate texting. I'll sometimes play some games, but that probably equals about half an hour's worth per charge, an hour at most. I'm also running juice defender, too.
With the new kernel I have the smartassv2 governor and have my processor speed between .128-1.113ghz. I think I did the battery calibration the correct way this time. I bumped charged it until it was completely charged. Then let it completely drain till it shut off yesterday. It lasted about 24 hours with the normal usage I have stated above. I then turned it on 2 more times to make sure the battery was completely drained. I took out the battery for a couple minutes and then put it back in. Then I let it charge off until the light turned green. I then booted into recovery and cleared battery stats. Rebooted the phone until it was completely started and then unplugged the phone.
I let the battery drain completely again and it lasted another 24 hours with the same usage I have stated above and I'm now charging again. I turned it back on while it's still charging though.
Is this normal battery life compared to you guys. Remember I have the 3500 mAh battery, but it was off ebay (stated new though). If you could also post you're battery usage and how long your battery lasts, as well. Also any other important info like, kernel, ROM used, CPU speed, etc. I'd like to compare to see how everyone else is doing. Thanks again.
I'm on CM7 right now with the latest Incredikernel. I use the Incredicontrol app to undervolt and set my frequencies from 128-921 Mhz. I have a standard battery and with light usage I get a day and half off a single charge, moderate/heavy usage it'll range from 12-20 hours.
You use any powersaving apps like Juicedefender? Also what do you classify as moderate/heavy usage? What battery governor do you use? Did you do a battery calibration?

I don't use Juicedefender or any power saving app like that. Moderate/Heavy use I mean texting all day making calls, on the internet, playing various games. Don't get me wrong there have been times that I kill my battery in less than 10 hours, but that's when I'm on my phone non stop or on Netflix. For a governor I use smartass, not smartassv2. I did calibrate my battery once, last year when I got the phone. To me what makes the biggest difference is undervolting with the Incredicontrol app. And the phone runs much cooler.
I might try undervolting to see how long that lasts. 1.113 ghz might be overkill, but I have noticed a performance increase. The majority of what kills my battery is the display though when I check out my battery stats. It's always at around 60%. I have the amoLED screen as well.

I always dim my screen as well. If its on the highest setting it'll kill a lot of your battery quick. I used to have my phone over clocked to 1.113 GHZ but after testing different things out I noticed if I lowered it under 1 GHZ there was not much of a diff. For undervolting I dropped the number by 25 at a time until I noticed the phone lagging. hope this info helps.
I have my screen on auto brightness. It's usually at a low bright setting unless I'm outside. I'll try out undervolting, too. I have noticed the phone does run a little bit snappier with the 1.113 ghz though, but I can live with it being a little less if it means better battery life.
I don't know if it's my battery or not though, but everytime I unplug it, it's been going right back down to like 89% within minutes. I understand that you can't fully charge the Li-ion batteries all the way, but I don't know if I'm fully utilizing the battery to it's full potential since it is 3500 mAh.
I might go back to my standard battery and see how it compares. Although I do like the feel of having the extra thickness with the bigger battery.

Charge it while its off or get an external charger. That's the only way to get a true 100% charge from a phone battery.
-My life is a shooting range, people never change-
Yeah, I have been bump charging as of lately(about a month), but I hear it decreases the life of the battery so I've been holding off on doing that.
With my latest charge, I've gotten 1d 14h 49m 20s, with moderate usage which I think is pretty impressive. It's still at 5% and I'm going to let it completely discharge and then charge it off again until the light turns green.
Edit: It lasted me right around 40 hours all together. It shut off so I decided to turn it back on and see how long it would last again. It was at 2% when I turned it back on and I got another half hour out of it which led me to the 40 hours. Do you think that's good battery life with a 3500 mAh battery?
Been trying to improve my battery life and I found this in my battery stats:
Cell standby: 41% (7% of time without a signal)
Phone idle: 35%
Android system: 10%
com.cooliris.media: 6% (Used to be default gallery, but I unintalled it)
Dialer: 6%
Display 3%
Is it normal for cell standby and phone idle to take up so much of the battery?
Yes. Cell takes up a lot of battery, especially if you are getting a low signal

If you use an app to reduce your minimum cpu mhz, the idle should take a bit less of battery

I already underclock my CPU. from 1GHz to 900Mhz, then at 30% battery life, goes down to 768Mhz, at 10% it only goes at 368Mhz.
And when the screen is off, it only goes at 245Mhz.

Are you using an app to get those results?
i work in an area where the signal coverage is really bad and when i leave with full battery in the morning, i get home even with ~50% only. the battery is basically killed just because it keeps searching for a network
I recently installed Cyanogen Mod 9 on my HTC Wildfire S but the battery only seems to last for 2 hours and 30 mins.
Any Suggestions?
Well that's quite abnormal. its not that bad.
battery life depends on various factors: Your charging level, Processor clocks and governers.
Also is your deep sleep working?
Install CPU Spy and see if its using the Deep Sleep state. You have to leave your phone on idle for a few minutes, without it on charge.
If my bluetooth is on my deep sleep doesn't work, even though this is supposed to be fixed.
My Battery Life is absolutely horrendous lately. Before after 8 hours moderate use, it would be about 50-60% remaining.
Now it's almost flat after 8 hours. No change in usage patterns.
I reverted to stock, cleaned the device of all apps and data, no change, it's still bad.
The only thing I noticed was that SetCPU says that 122Mhz frequency is unused. It uses all the others (including Deep Sleep).
Is this normal?
Does it sound like my battery is dying? (the phone is still within warranty... so should be covered)
I have also seen this. Anyone had any noticable difference with it?
When phone reaches 50% in battery level turn it off and pick out the battery for a few minutes. Put it back and connect the charger, now charge the phone turned off for about 5 hours or overnight. Start the phone as normal and check if the battery life time has improved.

I noticed that too.
Though I use No-frills CPU to set the min to 122MHz and max to 1024 MHz. my battery life is sucky too
Try Betterbatterystats
If your phone is rooted i think it voids the warranty on your phone

Rooting doesn't void your warranty. Unlocking your bootloader does.

I have exactly the same issue. My battery doesn't last longer than 8-10 hours of normal use. I use setCPU as well with 122 mHz. It will try that solution that CarzyPeter suggested

Hey guys.
For some days my battery drain is just horrible. I have 180mhz-1.2ghz deadline smartassv2 and i did play today Pokemon's with My Boy (gba EMU) and for atlast 30min my battery is over 55% (when i started it was about 90-95%)
Is there any battery calibration or smth like that?
I have lupus v12 with gin2jellybean 2.5.0

lol @ over 9000
As for battery, it can vary. Depends on age of your battery... After a year of constant two charges per day it can lost that much capacity.
What you can do is turn off phone over night and charge it while off around 8 hours, That should refresh you battery a little.
Also, after 30minutes of heavy gaming (as you said) does it stay on 55% or rise to 60% or more? If yes, then it's time to replace your battery.
And make sure you don't have any apps running in background (especially those who use wifi/3g)
IMHO, battery calibration apps are useless because stats are deleted by OS everytime you charge it over 90%
