Hello, I had similar problem - Wi-fi kept dropping out. However, by lucky chance, I have found what was causing it - for some reason, S4mini can't handle both Wi-Fi and BT on. Or to be precise: If you start Wi-Fi and THEN BT, it'll work till first sleep mode. ...and since I'm wearing MiBand for notifications, BT was always on in my case...
