^^ I am currently using Super Nexus Build 5 (Jelly Bean Stock 4.1.2) with Siyah latest Kernel (Overclocked CPU to 1.7 Ghz and GPU to max of 600 Mhz) Battery life is ok, considering I have Wifi or Data on all the time… With heavy usage like full time Wifi/Data on, Gaming for 1 hr, Browsing, Music/Videos etc - I get battery life of about 5 hours which is decent considering the heavy usage and hardware overclocking… But with minimal usage, I can get through 1.5 days… Not great, but also not bad…
