Hi shades,
Thanks for trying out nMedium!
I can't seem to find a setting to turn off repeat
Are you taking about with local (device) or remote (server) playback?
Currently there is no way to turn off repeat for local playback (I had a choice when it was coded to repeat or stop at the end - I thought that repeat was the better option). I could probably do something to allow you to toggle repeat via nMedium - but it's a bit of work and I'm really busy with my day job at the moment... I can add it to the list of enhancements if you'd really like to have it.
For remote playback, you can toggle repeat.
Go to 'playback options' in the menu drawer at the bottom of the playing now screen (click the triple dots to the right of the playback controls) - there's a selection on this options screen to select your repeat mode.
most concerning is that it is draining my Lumia 920 battery very fast.
This one is a little harder to diagnose - tho I doubt the issue is specifically an nMedium one. My last phone was a 920 - and it didn't have any specific battery issues - that I noticed.
When nMedium is not active on your phone screen (and I mean - actually visible on the screen), it, as with all WP apps, goes into a dormant state which uses no battery power.
If you are playing back audio locally, the audio system uses power - but the battery drain is the same no matter what app triggers the audio.
The biggest drains on phone battery life are the screen itself (when it is turned on) and any of the radio transmitters (Cellular, WiFi, Bluetooth). I've found that turning Bluetooth on only when I need it is a great benefit to battery life.
Does any of that help?
Feel free to reply here or PM me if you want some more info.
