Some days I'm happy, some days I'm not.
On the good days, I can get about 1-2 hrs over 24hrs standby and other times, a runaway app will just drain the battery from 90%to 50-60% in just an hour. It's always been this way on this phone. I try and close out all apps when I turn off the display but sometimes I forget and only notice when the battery drains severely. I have the gold 64GB T-Mobile Note 5. If I don't use the phone at all, it can easily go 24hrs on standby and the battery will be 90-92% after the 24hrs so yes, it's a problem with one of my daily use apps. I know which one but it's an app I use daily. That same app will not drain the battery on my S7 Edge, Note 4 or Note Edge, only the Note 5.
