Disclaimer : The organization Performance>Battery goes by how it is right from the box, No kernel APPs, no anything, just defult settings the kernels come with and what you should expect from those, however they are also a great guideline to know what you're going to get primarily, even after tweaking, This is based on My experience along with other User's from the Kernel's respective threads and from different ROM threads.
Best performance : https://www.androidfilehost.com/?fid=95916177934546156 And in case you're doubting here's a little peek from AnTuTu, Remember no tweaks
[Just for Reference, Stock is around 45k~46k.] , Daily usage is a bit faster too along with gaming, I suggest to add gboost and usbfast charge. However the battery life is like I've said down below IS lower than what it normally COULD be under the right tweaks [Compared to STOCK] but it still is a monstrous battery life (Compared to the other devices on the market hehe ), and if you LOVE [every other Kernel will only be less by what? 0.1 MS? This is for the powerusers] foresaid stuff such as gaming and multitasking this is the right choice .
Hybird going more towards performance : http://forum.xda-developers.com/htc-...antum-t2993647
All in one Hybrid : http://forum.xda-developers.com/htc-...x-001-t2881605 Recommendation : Universal ramdisk
Hybrid : http://forum.xda-developers.com/show....php?t=2705613 / http://forum.xda-developers.com/htc-...1-3-0-t2955537 Alternative [Port] for CDMA Devices ; VZW&Sprint.
Best Battery life : http://themikmik.com/showthread.php?...1%B4%B9-v2-1-0 - Read the thread and you'll understand why it has the best battery life, It's just stock with SUPPORT THAT YOU SHOULD HAVE, If you like STOCK kernel and wanna use MultiBoot this is the answer, Expect stock-like performance but a bit better battery.
Pick what you think is best for YOU, I have sorted it out based on performance > battery life (Furthermore all have great performance, SD Exceeds at that though.
My favorite Kernels Would be; Skydragon as I like squeezing my performance to the limit,Lyapota's kernel as it's working great overall but it can be iffy, BeyondStock since it's just the best solution for a roadwarrior and back2basic.
I would do the amount of bugs user's find and encounter however it's very user specific and mileage may vary, So sorting the kernels and organizing them by battery and performance is the best. [/QUOTE]

Battery saving tips....
for those wanted to squeeze as much juice as they can out of our m8's.
In accounts and sync go to google and uncheck any syncs you don't need,
In developer options uncheck show animations and allow mock locations,
In display and gestures uncheck ambient display you can also turn off motion gestures if you don't need them and then of auto brightness,
set your brightness manually and try to keep it below 30%
Set screen off time out to 30 seconds or less.
In sound settings uncheck pocket mode, sounds and vibrate.
Turn off auto sync and auto rotate.
use HTC power saver, most of the time performance is perfectly adequate unless playing high end games in which case to can turn it off,
Set GPS to device only not battery saving google messed that up lol.
You can download app ops from the playstore and deny wake up on syncing apps like google play services facebook and google + ect.
And of course greenify hibernate games and apps that are not in constant use,
it's not wise to hibernate sync apps like google+ and facebook and google services this leads to excessive wakelocks,
It's also not wise to hibernate system apps unless it's apps you can download from the playstore and they're not important.
Here is some great info on battery saving.
Here some some info thanks to @MassStash about mako hotplug it's interesting reading if your looking to try different hotplugs.
Some info on governors and schedulers again thanks@MassStash
I found this also it's pretty in depth.
IMO best free kernel tuning app.
Here is a modded Google Play services with less wakelocks.
Some info on PVS.bin
Here's a guide on tweaking interactive governor
Thanks @ MassStash
