According to manual, 4.5 hours with iOS, 1:40 with Android. Reason for difference is that RC presents a 500mA charge to an Android where app is able to turn off charging on iOS. Androids don't provide that function in its API.
Sounds like what I am getting with android, but was a bit surprised. I expected longer, but the charging explains it. Read the manual but seemed to haven missed that. Thanks
No, as the only one reported there, is the battery of the aircraft. This makes sense, as the aircraft is away (flying) and there is no other way of knowing, however the remote is in front of you with the battery indicator lights clearly visible.
