A device can reduce power or network activity when idle, depending on its operating system and settings. A connection that fails only after inactivity differs from one that stalls during continuous viewing. Check the platform's supported sleep behaviour.
Record the wake-up sequence
Note whether the player reconnects automatically, requires app reopening or restarts entirely. A television turning off an attached device's power can be another factor. Use the manufacturer's intended power arrangement before changing account settings.
Use supported options
Some platforms offer network-standby or energy-saving controls; others do not. Do not copy hidden settings from another operating system. Keep a note of the original value and consider household power use as well as convenience.
Test idle and active sessions separately
Let the device sit for the usual interval, then try playback. Compare with a continuous session of similar length. That distinguishes inactivity behaviour from a time-limited media session or general long-run instability.
