Thanks devs for this tuning update.
Now testing the out of the box pr1.3 w/o all the habitual performance enhancing utilities and tweaks.
Counting missed calls due to multitasking load, counting the uptime until reboot required to get things going smoothly again. Will evaluate later, but this could be a winner. (aprt from bluetooth peripheral support, pr1.2 was amazingly and uniquely feature complete to me)
So far, bat life seems very ok.
Also big thanks to devs of Swappolube and others to show Nokia the way while on pr1.2.
