What is the fastest/lightest weight custom ROM and most battery life conserving kernel for Nexus 4 these days? The last time I flashed a ROM and kernel was purity ROM with hellscore kernel on 4.4.2, so I am very out of the loop now that I am forced to flash again after my phone randomly got stuck on boot loop. From what I see online, Nexus 4 support has been understandably dropped due to the phone's age, and everyone seems divided as to what are good Roms and kernels for it now. So any opinions you can give are appreciated
