I installed this last night and my phone seems to be running great. I was still at 85% this morning after 4 hours off the charger and just over an hour of screen time, then I noticed that they released an updated version with specific versions depending on how much RAM your device has. I installed that and it reset my battery stats, so I will have to charge up and try again later.
I am running Task's latest 4.2.2 nightly and the most recent pegasusq/zen setup.
I am also using the init.d tweaks from this thread. The flashable zip makes things so much easier, but I have a request for a version that doesn't include all of the fun messages during the install process. This tweak takes longer to flash than my ROM, Kernel and Gapps combined! It's not that big of an issue, but I seem to be constantly flashing new ROM's these days and I get a little impatient.
