I think any electronic device with an electronic switch (vs. mechanical switch) will have some sort of parasitic drain on standby. I think, even if it's off unless the device is locked out but I could be wrong about that. Anyway, it should take years to drain a battery...Ive read the battery self discharges faster than the E switch drain.
yes, it is turned on. It's never been off since I bought it.
No, no different with an atty attached to it. (the numbers I posted are from a second test/monitoring..first test had the atty attached and showed even worse numbers-voltage was down to 4.01v from full charge and Radius was sitting for at least a day without any use on a fresh charge) also, I was thinking the battery might be the issue...nope, for the second test I used a different battery.
