Amazing  and I mean amazing(!) app if rooted. Still somewhat useful  (even if not) 4.4 KitKat and later OS KitKat and later reduced the utility of this app almost indescribably: If not routed now  you are seeing less than a tenth of what this app can do. Still  even now  unlike most great  pre-KK system diagnostic apps that are barely usable  it is still useful for sleep to awake tracking and list of system processes. If you're rooted  it's the holy grail of power leach finders: it gets right to the heart of the issue  and fast. No significant battery load either. If rooted  it is an absolute must have.
