no... wrong. sorry. ahah miui is most definitely a 2nd-init rom just like cm, justice, liquid, ssx and whatever else.however miui has gotten at least twice the battery!! not just for me but for almost everyone that has made the switch. 2nd-init is not to blame its something in these roms. seems cell standby or sometimes android system/android os drain way too much battery. especially liquid, absolutely TERRIBLE battery.. which is a shame cuz its my favorite rom :/ try miui out though. honestly the more i use it the more i like it, its been great. oh and miui gets this amzing battery all while running the v6 supercharger script!!! which has caused my battery to die quickly on other roms before
