I had the same problem, boot without going into recovery. I ended up on flashing stock rom and start from beginning. KingRoot (only) then NUT dual recovery and at the end SuperSU.zip.
From day to day battery works better :) while I have it for just over a month.
Sorry for two posts in a row but i couldn't edit previous... don't know why.
If I have to choose between this two I would buy Anker because it has very good reviews so I would rather pay more for something tested and recommended.
I have Mugen second week. I can use sensation couple hours longer without charging. Also notice some improvement with screen on time.
But for me it is to early for review. I will write my opinion after a longer time of using it.
I will try to add some screenshots in next few days. ;)
edit...
Is there any possibility to see screen with pattern request just after I turn on screen? Because now the first thing I have to do is to pull ring to the center of screen and only after that i can finally draw pattern.
Can I somehow skip the screen with the ring?
I'll be appreciate for any...

I just want to know your configuration so I have few questions :)
Which ROM you have? Is it GB or ICS?
Which kernel you're using? Did you change clock speed?
