I did see the current draw start to increase at about 70% volume and up. Its actually good to know. I'll have my radio, say outside, and have to run an errand or something and turn it off (soft) thinking I am saving battery. Now I know to turn it hard off.

Soft off until automatic shutdown just wastes battery capacity. I am up to 7 days since the last charge which is fine. If I had used the hard power off when the battery was new I might have managed 14 days.

Re: [SlimDevices: Radio] Radio run time on battery
For completeness ~ I reran the test with the kill a watt and a SB Radio. The meter measures voltage (119vac), frequency (60Hz), current, wattage, power factor, and VA. So, I recorded the wattage, VA, and PF readings, as the the load seemed to change reactively, changing the PF. Results below. Note that I also (as a check) calculated PF = W/VA, and there is a bit of a different from the readings, but at lower values, so perhaps resolution comes in to play. Note there are some goofy things too, like playing at 50% volume lowering the VA. 37661 Observation, soft power off (Clock Screen Saver) isn't off much at all. Perhaps only the audio amp gets turned off? You can hear it come on and off. So @Slarti, looks like you either have to hard power off, or plug it back in when not in use :). I usually eventually plug mine in before the end of the day after using on battery. I have not run the straight DC test, I do have the bits and pieces to do it, but am thinking it might be moot at this point. @POMDev - Please help check my work, it's early in the AM again :rolleyes: Jim +---+ |Filename: radio and kaw.png| |Download: http://forums.slimdevices.com/attachment.php?attachmentid=37661| +---+ Redrum's Profile: http://forums.slimdevices.com/member.php?userid=33806 View this thread: http://forums.slimdevices.com/showthread.php?t=116234 ___ Radio mailing list Radio@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/radio

I am wondering if others out there with problems in this thread (hello?!) might try sync. What's weird is in my experience if one player (in my case a receiver) struggled, all others synced struggled as well (rebuffering, then back, repeat cycle). So, sync made it worse. I am also not sure of the exact mechanism that LMS uses in sync that is not present in a normal stream. Maybe one of the devs might be able to shed some insight. If curious maybe you could try both internet streams and your own library, and also a different type of player (if you have one, or use something like squeezelite-X if you have a PC) as the sync healer.
