Left both MW07 and MTW alone for 8 days with a full charge. MTW is on 1.25 firmware. Plugged both cases in. MW07 buds and case showed fully charged in less than 3 minutes. MTW is at 45 min and counting, still charging. So that problem is not “fixed.” BUT the IEMs themselves weren’t dead - they were at 20%. So I guess that’s some improvement.
