So First of all i have a Samsung Galaxy SII Gt-i9100 with Official Kernel and 4.1.2Jb
Overall, Jelly bean is good but not on the S2, still a noticable speed difference with its successor i9300
I Looked up some ROMS on Cyanogen website, And i looked for Stable roms, and the latest stable version is this one
I really don't know what they exactly mean by "Stable" and All i'm worried about is the battery life, i want a better battery life than the one i already have, and i would really appreciate some guidance from you experienced S2 users in choosing a custom Kernel that suits my needs which are nothing but good battery life and no random reboots. i heard Siyah kernels are pretty good and cyanogen's too.
And all Cyanogen ROM Suggestions are highly appreciated.
Thanks for reading
