Here is a cheap and simple and most importantly a reliable way to fix this issue.
The text explanation...
Buy the official extended battery. Its very cheap, got mine for 30 aud.
Install the terminal emulator app. It places an icon notification and thus is the only app that doesn't keep getting killed in the background and consequently stops helping with the wake up lag.
Side effect... you also know if ur phone reboots hot or cold, u get some insight on your stability.
The graphical explanation...
Below are some screens on my setup. I use AOKP and Fluxxi kernel.
