    Low voltage causes high Android System?

    With low voltage kernels I seem to get a high Android System in battery, and take a huge hit. Is this standard or am I doing something wrong here?

    I am using P3's kernel on UD right now.
    I have done the same on CN1 ulv and it seemed to have the same problem. I have searched and haven't found any info on the matter.

    They were both at stock speeds since I rarely have to go higher.

    I know that PS3 has standard voltage kernels.... Try looking in Rom Manager, if I'm not mistaking the kernels ate under Slayher.... I had the same problem with the PS3 1.6 lv 1200 kernel, so I just went back to the original kernel that came with UD and now my phone runs smoothly with no issues

    I remember reading that other people have run into issues with P3 kernels and UD. The ROM comes with a slayher kernel so you should give one of them a try and see if you have better results.

    Ah yes, I am sure I can just switch it to a standard voltage module, just wondering if this was common. I was also looking up some things, kingklick had some interesting properties, but I am not sure if I can run them, I read about them being used on Droid, but it might have just been the 'Droid name.

    If this is a standard problem, I do not see why it isn't reported more.
    If this information was out there, it could save a lot of trouble for users, unless it is isolated.

    I know my phone runs better with standard voltage kernels also. Some phones just don't do as well with the low voltage. This is a long read but has some good info about overclocking

    Thank you for pointing out that thread.
    I've read it and even talked to Skull One.
    I get more confused everytime I read that thread.


    (The info isn't bad, its just overbearing and I'm an experienced overclocker, it just confuses me since it lists so much stuff.)

    Two things:

    1) Have you noticed a drop in battery life over stock voltage or any other performance issues or just a high percentage of Android System?

    2) Some phones can't handle LV kernels, but if you can run a ULV kernel the LV shouldn't be an issue. If the voltage is a problem then you'll notice lag and tremendous heat buildup, random reboots, etc, because the hardware is malfunctioning. The ECC kicks in and heat levels jump, the phone will lag, etc. Have you noticed any of this?

    Yes, I could get 3 days on low usage, now it drains 10% in ten minutes while I do nothing.

    I flashed a kingklick kernel once, it didn't work so I reverted back to the stuff I was using before. The only reason I mention that is because after that, it went from 80% to 50%. I'll recalibrate.

    I ran an ULV, and it was warmer than usual, but never dangerously hot. There was a little lag, but probably due to clocking lower rather than the kernel not working as intended.

    Okay, flashed to a standard voltage P3 kernel, the drain is still there. This occurred after the bad kernel flash, so I will restore nandroid and see if this was the main cause of the high battery drain. I've experienced Android System taking more battery on lower voltages though, still wondering is this common?

    Odd, after the restore I get a lot of force closes, just like I did before the NANDROID restore.
