Phone with nlpcollector wakelock means that something is trying to find your position/location using WiFi&mobile network location option under GPS,,, try disabling that option under GPS and hopefully the wakelock will clear out.
Still u need to find out what app is constantly asking for ur location and greenify that if u need that option enabled.
I personally keep GPS off and manually enable it whenever needed to enable any wakelocks it may cause.
The Phone: LG G2 D802.
The Rom: Aeonflex latest.
The Kernel: Always Dori Powered.
