20160122
I thought I'd share my experience with agsola's 20160122 (two cores online enabled) so far, though it's too early to draw any kind of conclusion from it.
I've been running this since yesterday morning and left the phone off charge overnight. It lost 10% battery over 8 hours. I don't think this is more than normal, but if it is, it is only
very marginally more. At any rate, I don't have a comparison against the same build without the two cores online, so it's anecdotal at best. I think general performance is slightly better, but again, could be a bit of placebo playing in.
@agsola: From what I can see the changes for enabling two cores online is not in your repo, is that right? I built your repo locally yesterday morning so if not it should be an exact match apart from those changes. I'm newbie at building CM though and I haven't tried this build myself yet. I will try to flash it later to check overnight usage for a more direct comparison.
