Yes you can use any though I don't see why you would want to use the Bullet kernel. Not to say that its not good but it hasn't been updated in a long time and all the current ones are better performance-wise.

But you upgraded your phone right? Maybe it's time to upgrade your kernel too ;)

(darkside kernel's the best of the best)

I think Eugene's kernel is one of the best but I just say that because I haven't really given dark sides to much of an opportunity. I'm guessing that's the same with you and Eugene's kernel

Guilty as charged! I gave macnut a twirl but LG is not really to my liking and so I never got to use streamline again. But with darkside I'm running it underclocked @1.35Ghz and undervolted by -112.5mV. Your mileage will vary with how much you can undervolt it and get away with it.

K so I know how to under clock but I'm a noob with undervolting. Do I have to under volt the amount you said to all the frequencies?

Start with -50mV across the board and work your way down from there to see how your phone reacts. I have Darksides ROM at Min 384/Max 1.51GHz and undervolted at -50mV across the board and it works quite well. I might give -100mV a shot to see how it goes.

Yesssir I'll give that a go. I'll update later, the minimum for each frequency is 800mV correct? At -50 I have the first bottom five at 800mV

You can technically go lower than 800 but it was posted at one point that any lower than that causes more battery drain than it saves (I'm not sure why though). Things to look for when you're undervolting: if you're off the mark by more than 2-3 steps (12.5mV per step), your phone will reboot on the spot. If you're off by just one step, your phone well generally work fine but will randomly reboot on occasion. For me, if I go to -125 and I leave my phone alone for around 20 min it will reboot. But I get no reboots at 112.5.

Something to keep in mind though: undervolting isn't linear which means that while my 112.5 works for my underclocked processor at 1.3GHz, it doesn't work at 1.7 GHz. The higher you run your processor the less you can globally undervolt.

Okay cool I'll keep that in mind. I'm on stock frequency at 1.51GHz and at -50mV. So far so good, I'll give it like 2-3 marks less later and see how that works. Thanks again for your help

Thanks much for this, I undervolted too much and now my battery is draining like crazy. I was at -100mV and was fixing to flash the kernel all over again, saved me a good 5 minutes thanks :)
