Thumbs up [Q] n7105_CM11_4.4.2

May i check whats the best kernel when using this ROM? I notice my batt life sux after running this stock CM11 kernel.

Also is it me or is the ROM works this way. I am unable to uninstall the bloatware. Tried titanium or clean master but it won't work despite already having root access.

Appreciate if anyone can share with me your experience!
