ART really needs the framework and apps to be compliant. It is a crap shoot with KitKat, depending on the apps and what junk is running in the background. Since Verizon is infamous for being the bloat kings, not surprising there are issues
Seriously though, the actual improvements in relation to stability and storage space being used is NOT worth it with ART. Folks with only about 4GB free right now on their devices will have a rude awakening when L is released.
ART needs a LOT of room to behave. If a lighter app user, no harm no foul. If a gamer, you will probably be pi$$ed at the tradeoff of storage for nominal improvements.
Folks could be best served to step back and consider the actual weight of what uses the battery on their device. Most of the weight is the display, chipset and radios. The actual improvement of a few hundred less Mghz of process time for running apps intermittently is NOMINAL in relation to the total battery usage weight of a device.
Folks seeing "amazing" battery life or "super speedy" response are respectfully potential candidates for placebo studies
Yep, depending on what apps you use, how you use them and other settings on your device, you could see some improvement, but neither significant or profound. Sometimes the actual improvement noticed is temporary, since part of the normal recompile process is system level cache cleaning as well.
Same thing as resetting to stock and the device is super speedy. Until you start actually doing stuff on the device for a few days
