This kernel with viper gives me incredible battery life...typically 18-20 hours with moderate/heavy use during the day

Took me 30 seconds of searching from the tapatalk beta search tool.

Yeah sorry, I was a little overwhelmed with the site at first. I too found it via Search. Thanks for your help.
Just saw that 2.06 source has been released. Will there be another update?

The 2.06 download is the URL as the 2.04 download. When 2.06 was released, it didn't look like there were any kernel changes and it looks like they just published the same download to make that official...
yep, 2.04=2.06. Even kallsyms are identical, so it wasn't even recompiled. This is why dnashellroot.apk worked on both kernels.
I just got these results yesterday with heavy usage, no calls though. I am on the newest version of Viper. I had wifi on and connected almost the entire time. 5 hours of screen on time is pretty awesome. However I do feel like msm_hsic_host is still running more than it should, my phone was still awake with the screen off for about an hour. Is being awake with the screen off 6-7% of total uptime pretty good? Also I wish I could get Facebook to stop, Greenify won't work on it. I also have Beautiful Widgets set to only update every 3 hours, I don't know why it's waking the phone so much.
Pretty tough to get better battery life than that...lol
Better Battery Stats has your msm_hsic_host at 1%...which is great. Other programs will report that as much different /higher than BBS.
Not sure which one is right, but on days I'm really impressed with my battery life, the msm_hsic is reported very low on BBS whereas it tends to be reported higher on GSAM...so I tend to believe BBS. I mainly use GSAM to see if I have any apps that went haywire.
I always have gotten great battery life on Elkay's 096...great kernel,
I was using crpalmer's but I was having issues with msm_hsic_host keeping my phone awake, which is why I started using LK.
if you are still using Viper or other Sense based ROM, beaups posted his personalized kernel built off of LKs here with other awesome fixes. Its on page 2 of this thread....(not this specific thread, page 2 of the original android dev thread) I get very good performance and battery life with it.
that is probably caused by apps, not kernel. I am running an aosp based rom and I do not have any hsic issues with crpalmers.

48Hello! Here's an HTC DNA kernel with system write access based off HTC's 2.04.605.2 source. While system write is awesome for those without s-off, there are just a few other things some of us desire while maintaining stability of our DNAs. The most glaring thing to me was the horrible standby battery time on our stock phones. The issue is due to a wakelock of msm_hsic_host that prevents the phone from going into deep sleep. This absolutely kills standby time. I've put fixes into place to correct this issue. I'll likely be adding some additional features to this kernel, but I won't be going crazy. My main concern with this kernel is stability and good battery life, so if you're looking for a benchmarking kernel you should probably try a different one for now. Don't ask for release dates!
Installation:
You must be unlocked and rooted to install this kernel. The process to unlock and root are covered in other threads dealing directly with those tasks. If you are unfamiliar with Recovery Mode or fastboot, this modification is not yet for you and you should read up on those things first. There's always the potential that you may damage your phone with any system modification, and by installing and using this kernel you take full responsibility for any damage you may cause to your phone. Download the zip file for the version you want to install. This zip file should be extracted on your computer and contains a boot.img file that needs to be flashed in fastboot, as well as another zip file containing the modules which must be put on your phone's storage and installed in Recovery Mode. DO NOT INSTALL THE FULL DOWNLOADED ZIP FILE IN RECOVERY. After flashing boot.img and installing the modules zip file, make sure you wipe your cache and Dalvik (recommended with each update, too).

Awesome! I started a new job Monday so I might not get around to digging into their code until this weekend, but I'll make sure to get you guys a build ASAP.
8Just to clear some things up.
I fixed my return to stock flash, thanks elkay for pointing out my derp.
Second, you only need to flash that if coming from my custom kernel, not any of the stock based ones. On the custom one, I remove some files from your phone because the functions are built into the custom kernel. Flashing that file puts them back.

You're correct in that when flashing Viper as a clean install after full wipe, you don't need modules for the dsb kernel since they're built in to the ROM. However, to change to elkays kernel, you must flash the DNA.Stock.Kernel.Modules.Fixed.zip module to restore the missing stock files, then flash the new kernel. It's really a quick and painless procedure, but has to be done in correct sequence.
So what you should do now to set things straight, and might as well move on elkay 0.9.4:
1. Download and unzip the LK_DNA_0.9.4.zip file on your "SD"
2. Download but leave zipped the DNA.Stock.Kernel.Modules.Fixed.zip file.
3. Use flash GUI to flash boot.img file in unzipped LK_DNA_0.9.4 folder. (same as flashing boot.img through adb in bootloader with "fastboot flash boot boot.img" but a hell of a lot quicker).
4. Reboot to recovery.
5. Clear cache and dalvik cache, flash DNA.Stock.Kernel.Modules.Fixed.zip then flash LK_DNA.Modules.zip in the unzipped LK_DNA_0.9.4 folder. You can do all that in one recovery session without rebooting.
5. Now reboot. Bet things will be a lot better.:good:
