HD+ Better Battery Life - your experience is welcome

[mr72]

I spent a whole lot of time fiddling with my Nook Color to get really great battery life from it. On CM7.2 or derivative, with the right settings, I got up to 17 hours of screen-on time reading books (no wifi) and once flying home from Europe I watched movies for 10 hours straight... although the battery was just about dead then. When the NC started to really go south I bought an HD+. I'm super happy with the HD+. I just need to figure out a way to get some more battery from it.

I am running the mid-July build of CM10.1 on EMMC and there appears to be far fewer tweaks available with CM10.1 than there was with CM7 to improve or tune battery performance. I watched one movie (stored on SD) and it consumed over 50% of the battery life. I am getting more like 10 hours of reading books out of mine.

My goal is to get 16+ hours reading (using Moon+ Reader and epubs) and 8+ hours of movies (MX Player). Any suggestions on what I can do to get it there? Is there a kernel with clocking yet? I think underclocking while reading books is one key to long battery life in that case.

Well #1 thing u should do is disable ALL location based settings, including within google maps. This drains battery significantly.

If you could afford it, get rid of all Push notifications...

Well, other than that, there is really nothing else I could think of other than brightness down and exit all apps.

TBH, the battery on CM10.2 I'm using is pretty good w/o underclocking or w.e.

Yeah I've done all that. I actually went ahead and upgraded to the 9/01 build of CM10.2 in hopes that it would have more options for battery life improvement, and it does. Unfortunately some of my apps won't work, but I'll see about sorting that out later.
