    The battery & performance are already pretty good, it really depends on what apps you have installed. To improve battery further, turn off 3G data or disable apps that update using 3G data in the background or use some sort of app like Juice Defender to automate this. To improve performance (at the risk of battery power), overclock or use Interactive/Smartass Governor instead of Ondemand. Although I don't think the slight gain is worth it.
    Thanks. Do these roms have the dalvik cache to cache mod? If so, what happens if i select the wipe dalvik cache option from recovery?

    Yes, I've added a few tweaks in the latest builds of BACKside to allow for bootsounds, a wifi patch we are testing, and to add the video icon into the app drawer. Since the begining I also changed the bootanimation and updater-script to make things a bit less boring during installs.

    IHO does have the dalvik to cache mod, it's the first script in init.d

    I was loving this rom until I noticed the terrible battery life. I had everything turned off. I removed all uneeded apps and moved apps to sd. Battery was going down fast just by moving around on the home screen. Went back to bumblebee.

    Not a fan of the new startup sound. Phone automatically rebooted at work and although the volume was off and headphones were in, it played full volume throughout the office. Had to pull the battery and now I can't turn my phone on. Will be deleting it as soon as possible...
    Even if you have everything turned off the boot sound will play no matter what. If you forget next time you update and it happens slap the phone under your but. I dont have a big butt and its muffled enough most people would think it was somebodies headphones got turned up on accident.

    I just noticed that my notification tone that plays isn't the one I have set to play, its not a problem its just strang, by the way I love the boot sound, I'm looking for an animation to match now
    Jerry has idea he is working on. I wont mention it right now but stay tuned. I also did some looking around and will be trying a couple things. Most boot animations readily available are focused on android or the phone itself.

    IIRC you also have tons and tons of things you shut off to "save" battery. Turning everything off will hurt you more then letting some things run. Not sure what you have your clock settings at but its been shown 480 will be the best minimum speed for 90% of the people.

    Why not do this, install the rom set it up like you would bumblebee then run a log cat for an hour. Post that on pastebin and on github. Then revert to stock setting and do the same. Saying it has terrible battery life and not helping by posting a logcat is just uneeded fluff.

    Dont take that as a insult but more of a give more to get more suggestion.

    Well I set it to 806-787 just like I have it on bumblebee. It drained like 10% off a full charge in about 3 hours of mostly standby and a few texts. I had 3g off. That was never a problem with bumblebee. I flashed back to bumblebee and got about 25mb of ram back which were used up in IHO. Im just saying. I think this rom is awesome, but to me battery life is one of the most important things. 480 isnt the best min speed for battery life. For the best battery life set it to 806-806 max and min. 806 uses the least amount of power to complete tasks. I personally have it on 806-787 since my optimus would reboot sometimes on 806-806, but thats cause my optimus is pretty lazy and 806 is is the highest it goes.

    Why would you have your cpu at max speeds all the time? Bring the min speed way down and then talk about battery life.

    I believe there used to be a thread where someone tested various ROMs & min/max CPU settings, and reached the conclusion that increasing the min CPU didn't drain more battery, but just finished whatever calculations faster. But I think they were all done using one kernel (Picasticks?), and it may not apply to other kernels like today. I use mine at default 245/600 Ondemand and get great battery life & runs pretty smooth.

    Check the sticky and find the threads on battery tests by Marzz and read the whole thread.
    You are working on incorrect and early information that was later updated in the thread. Some of which I post below.

    Also, a LAZY Optimus at 806?
    You need to do some research. Very few go any higher and it has been shown that running at absolute max speed is bad for battery. Most cannot go above mid 700's stable and you still need to come down a setting or two from peak for the best efficiency.

    Min CPU does have an effect.
    Too low and the CPU spikes to 100% and stays there until it has completed the task. This isn't a problem on something short term, however, listening to streaming music can exceed 245 processing power so your cpu will continuously run at 100% the entire time you listen to streaming music. You need to find a happy medium. This is why I put overclock recommendations on Harmonia of a minimum of 400. Too high and you waste battery at idle, too low and you waste battery anytime anything minor runs.

    Granted this research was based on Froyo, but likely holds true on GB as well.

    I have never had a problem with my phone running at 864max and 844min. It seems stable, every app works, and battery life is great in my opinion.

    Running you CPU at max speed 24/7 isn't going to do you any favors for battery life or the life of the CPU in general.

    I'd like to see real tests on GB instead of just assuming it's the same. It could've been in Froyo ROMs, the kernel or something internal wasn't efficient and triggered the CPU spikes that kept it running at higher CPU. Gingerbread also has a lot of internal updates so it may be perfectly fine streaming or doing other low-demand activties at 245 Mhz.

    You are misinformed. However you did read part of that thread mmarz posted. I give you that.

    I believe there used to be a thread where someone tested various ROMs & min/max CPU settings, and reached the conclusion that increasing the min CPU didn't drain more battery, but just finished whatever calculations faster. But I think they were all done using one kernel (Picasticks?), and it may not apply to other kernels like today.

    The test was by mmarz and used the recommended kernel for each rom. They were a mix of Froyo and Gingerbread roms.

    LeslieAnn is correct on everything mmarz posted two threads and by the end of the second one had come to the conclusion above. However the tests were perfromed on both Froyo and GB.

    The tests where conducted on 2.3/Gingerbread the early adaptations of the rom by aSOP and Zefie.
    Here are the links. Yes they should be updated with the new roms but they are a basic idea.

    Ok I consider my optimus lazy because my other optimus with bad esn can go up to 864 completely stable. It clearly showed on one of mmarz's graphs that 806 was the most efficient and used the least amount of power to complete tasks. The slower speeds used the most power. I think its actually comon sense, faster speeds-less time to finish tasks-more battery savings. Thats my opinion though.

    Now back to topic. All I said was that backside rom had bad battery life compared to bumblebee. I used the same settings and apps for both. Could be gingerbreads features? Or could be that bumblebee has many more tweaks and mods which give better battery life? Only JerryScript and obijohn would know.

    806-806 are the same speeds that I use on bumblebee and the battery life is much, much better than backside. And it shouldnt have to do with the kernel but with this specific phone.

    And there is people here telling you that you are clocking WAY to high on the minimum side.
    Here is mmarz final conclusion. I tend to think you read the first page and stopped.


    I've been busy with a few other projects (my CNC mill blew up yesterday), otherwise I've finished my last round of tests. I need to write it up and I'll post it within a few days.

    Topics I will cover:
    How your Kernel effects battery life
    How your Rom effects battery life
    The ultimate system settings to get the most out of your phone.

    @ theboundless
    I may have been a bit hasty with my conclusion that you should set the min and max CPU speed to the same value. Here are situations where this would hurt battery life:
    Streaming music
    Surfing the web
    Talking on the phone
    Or any other low CPU intensive, extended period task.

    Here are situations where it will help:
    Leaving the phone on idle and having occasional tasks occur (check GPS location)
    Editing files
    Downloading/uploading files
    Or any other finite time task

    By not wasting time with the lower clock speed, your system should finish these types of tasks using less energy than if your system had attempted a lower less efficient clock speed first. If you are just concerned about standby battery life, setting both the min/max to the highest stable clock speed will help.

    Try this, flash nothing but a rom and setcpu. Set the min/max to the same high value. Test how long the phone lasts. Now set the min low and the max to 600. You'll probably notice a decrease in battery life.

    You talk about trying different kernels and roms to get better battery life. Here is a little spoiler on what I will post in my last set of tests. Your rom/kernel have little to no effect on your battery life. No matter what you have flashed, you can manually change your settings/uninstall apps and get the best battery life out of your phone. If you suffer poor battery life on the Optimus V (less than 24 hours), it is because of one of the following:
    You are a heavy user of your phone
    You have installed applications battery hungry applications
    You have flashed a rom/kernel that has a bug

    If your rom/kernel has no bugs, you should get over two days of standby time with minimal use.
    This was pre IHO 2.3.4/5 and there has been some significate changes to the kernel and overall how the rom works.

    You want awesome battery with a awesome rom. Take the advise given and instead of being hard-headed and thinking shutting everything down and ramping the cpu to max is super duper awesome.
