sorry m1cha, but for me cm10.2 dont reach the battery life of miui\aosp.. hardly 12 up time\3 screen on here..
do not feel offended, I really appreciate your work and your efforts, your rom in fact are the best, the fastest and fluid, and although the average battery life exceeds the roms with kernel ivan, is not yet able to approach the optimal battery life that could give mi2\s. However, its already okay, because you do it for free, and in your free time, and you did an impressive work for our community. And also, i think that with the next relase of franko kernel (if you do that), battery performance will largely increase, because even in nexus 4, cm kernel consumes too much battery. Thx for your efforts.
Just my two cents.
