    how can you tell if its a specific rom or kernel or speed your set at killing the battery i know in battery use you could see other details but how can you really decide which it is

    my phone has been on for 3 hours

    i had one short phone call
    some texting
    and very light browsing

    and im down to 70 percent

    im on the latest beast froyo
    with chevys lv 1.1 kernel but right now set at 1.0

    and in the past few nights ive noticed that when i get down to like 40 percent it pretty much skips 30 and goes straight to 20

    The only way I know how to do this is to run a day or two on the stock kernel that came with the ROM and then start trying other kernels.

    For this part, if you are talking about the battery percentage in the notification bar... it will only read in 20% increments, this is a standard Android thing... It will go 100/80/60/40/20/dead

    Wrong, the battery goes 100/80/60/40/20/10/dead.

    I thought I saw 15% somewhere. Maybe that was on a pop up or something.

    The Droid reports battery life in 10% increments. It did on 2.0.1 and 2.1 and also does on 2.2. Other Android phones report in 5% increments (and maybe even 1% increments). It depends on the hardware. The battery app I use still reports in 10% increments on Froyo, just like it did on 2.1.

    I've been having some similar issues with 2.2. Most of my battery drain I found out was coming from my Engadget widget trying to update constantly.

    But since 2.2, I've seen my battery jump 20% instantly too. Just today, I went to use the browser, before I started I was at 70%, I opened the browser for like literally a minute, closed it and I was at 50%. So I would like to figure this out too. It's happened across the original vanilla 2.2, FRF57 and NexBeast v0.1.1. So I don't think it's a specific ROM issue, maybe an issue with FRF57 based ROMs.

    Have you checked to see what is using the battery up the most? Could be an app not playing well with 2.2

    My 2-part philosophy is summed up in these acronyms:

    WEB = Widgets Eat Battery

    -and-

    KISS = well... you know...

    I think the only way to know if a rom or kernel is causing battery drain is to change said rom or kernel

    Easiest way would be to change the kernel. Then if it is still the same change the ROM.
