I had battery guru installed on my note 4. Went through the learning curve of three days. And after a further 2 days it started reporting it's activities.
Pro; managed wifi very well. Recognised when I left home would switch off and on as I got into favourite wifi range. Managed activities well. Reported 8 to 9 hrs inactive for evening and night
Cons; something kept the phone from deep sleep. It would show awake time equal to the time switched on.
I averaged 30 hrs of which 8-9 would be night after installing.
I sent the images to qualcomm support. Other than an email to say they are looking into the issue, nothing.
I have un-installed it this morning. Hopeful to get back to 40 hrs plus on a single charge.
