I asked this here because the GNex is so hot right now, but it can apply to any phone. I finally got a friend to root my phone for me (he volunteered!). I have an OG Droid, running CM7 (2.3.7) and even at 600 mhz, I notice a much faster battery drain than Froyo had. I did just go to 550, which I believe is stock, so I'll see what that does. Overall, it runs well. Seems smooth, and without the bloat, and especially evil facebook app which ruined my phone before, there aren't any issues beyond just tweaking and adjustment. My real question is when I retire my Droid after I use my April upgrade, would I save a significant amount of battery if I got something like the Gnex, Rezound, etc and underclocked them by about a third or so? Right now, if things are good at 600 mhz with only 256 megs of ram, wouldn't 800mhz - 1ghz instead of 1.2-1.5 with the 1gig of ram be just fine like that? I plan on rooting and using a similar ROM based on ICS at that point, because I love this one, not to say there aren't more that are great too. I was just wondering if there are any holes in my theory as far as underclocking to save battery and depending more on the ram, which to me seems even more important when multitasking. I agree lots of things make a difference, this is only part of the equation. I'm not expecting to tweak the processor speed down and then not charge my phone for days, that's ridiculous. Eventually, I'll be able to run everything I WANT not just everything I NEED like I do currently. Love my OG Droid, and rooting makes me far less likely to die from waiting to retire it, but I am looking towards the future. Love to hear some thoughts on this, and for the record, I did my best to absorb information, but I'm far from ready to do all the work myself again next time!
