Hi there,
Recently I bought broken Bowers & Wilkins PX7 S2, the problem with them is that battery discharges on its own even with headphones turned off. It is a quite common issue with this model and even with model higher PX8.

To check if I'm correct I bought another PX7 S2 working one and replaced small charging board with this IC and problem solved, battery no more drains on its own. After changing board back to original problem returned so I'm 100% sure problem...05-30-2025, 01:11 PM -

Of course it would be amazing if that had fixed the console, but things are never so simple.
