Yeah, me too :headbang:
Several users have demonstrated that the batteries are not the problem as they don't lose charge if removed from the S1 Pro . There is something going on in the S1 Pro that draws an excessive amount of current when the device is switched off. Li-Ion batteries have a self discharge of less that 3% a month even when taking into account the charge/discharge monitoring circuitry so that doesn't account for it. Bose even acknowledge that there is a problem with some S1 Pros and recommend removing the battery as a temporary fix.
