Root Low Voltage Kernal by ejhart

just try it out... i use the undervolt and overclocked kernel and it is actually better to me
Click to expand...

I'm the undervolt kernel, the oc/uv put me in a boot loop so i thought i'd try the uv. i put in my new 1500 oem battery yesterday and loaded this kernel. i've been off the charger for about 2 hrs now this morning and i'm at 98% still although i've barely used my phone today.
 
I first tried the undervolt/overclock+N and noticed a pretty big drop in life.

I just started using the undervolt+N (stock clock) and battery life seems largely improved. Only seeing about 1-1.5% drop an hour as phone is in idle on a 1500mah battery.

i'm at 80% now after being off the charger for just over 5 hrs with the same battery and kernel as you. this was with fairly light use though, still pretty satisfied.
 
thats good and when i say i have the hybrid kernel im still using the first one... its seem to be the most stable and i dont know why he has made ones that are worse? but v7 has just released so i may try the new one her released
 
I'm running the undervolt + N kernel (first version, not the new 0.2) and I thought my battery life was pretty bad the first cycle after I installed it, but after that it's been fantastic. When the phone is off it seems to take no power at all. This is on the stock battery, too. Wonder how long I could get on my usage with the 1500 mAh battery... :)
 
Anybody have any ideas on how to verify that the WiFi is running at Wireless-N speeds? I have my AP set up on G/N mixed mode and in the wireless settings page it shows 54Mbps as my speed still even after flashing and validating the kernel is installed.

wondering this myself, is there a setting to activate n or is it just on?

activate N only on your wireless router through its menu and see if your phone connects... thats how i figured it out.. also when you look in your wifi menu on your phone and click on your network it should say speed of 65mbps or higher not 54 since thats G

My incredible connects to my Airport Extreme as:

b/g/n with a rate of 65

My laptop connects with:

b/g with a rate of 54

I named my 5 Ghz network differently and neither device can see it. I assume this is because neither device supports 5 Ghz (cheap wifi card in laptop).

Maybe the incredible only supports 2.4ghz?

that is correct we only support 2.4 i think
 
I have the uv kernel right now and it works great. If I want to go back to stock kernel, or change to of, do I need to do a full nand restore or advanced restore and boot restore?
 
Thanks for the tips guys, I actually figured out its something with my router's firmware. The build of DD-WRT I'm running seems to have issues with N. My buddy's newer build of DD-WRT on the same router worked fine for my DInc at N speeds.

Based on that, I would expect the phone to run about 3-4x as long with undervolting. But how fast is the CPU running (at max) ? Can you use System Panel and figure it out?

Can anyone please confirm how much longer the phone lasts with the 1500 OEM (or even stock 1300) ?

I'd love to know the differential. I'd appreciate if someone could list usage parameters - BT, 3G, WiFi, Nav, calls, texts, browsing, etc. - as well.
 
So I tried out the oc/uv and got stuck in rebooting. When I did a boot restore, I lost WiFi. It said it was unavailable. I had to reload the uv kernel that I previously had. Any idea why it lost WiFi? How do I get it back if I want to go back to stock?

try the overvolt undervolt file its just a step up in volts from the original uv file but made my DINC not hang like the main oc uv n file. theres like 3 steps to the undervolt files go to his website and read it but its something like this

"Try the 1st link (in overclock section) FIRST, only if you have stability issues (bootloop/lockup) should you then move on to the 3rd link with the slight overvolt at the 1.15ghz slot. If the third link fails for you then there is still hope, move on to the 5th link. If you need the kernels without wireless N use 2nd link then 4th link and last 6th link if all else fails. If by some slim chance NONE of these work for you, stick with the stock speed undervolt kernel in the very first links of this blog."
 
Ok I've come across the need for wireless N now so I'm leaning toward trying the undervolt with N and no overclock again. What's with the old vs. newer kernel. Can someone point me toward the most stable undervolt + N?

Can't hurt to try...giving the new UV + N a try, will report back.

LOL i've just done this, currently using this right now.

I don't have a wireless N router, do you know how to check if I had correctly enabled wireless N on my phone?

I assume if this kernel is running well, and my wifi is fine, I should have done it correctly?
 
Based on reports of occasional issues, I guess the first thing is to try wireless tether to make sure it's still working ok. I can't test my N yet either because I don't have it at home, there's a wireless access point at work that I loaded it for so I'll find out tomorrow. If there's a way to tell otherwise, I don't really know it.

I was just planning to check my connection at Settings > Wireless and Networks and hope the N is showing up as something greater than 54 mbps that my 802.11g Linksys provides. :D
