I submitted a ticket back in Jan and reopened one today asking about the v1.05 firmware issue regarding less playing time...here is the response....(my replacement g10t should be here by Friday....the first one didn't hold a charge at all)
Robert, Thanks for the reply. The update reduces the charge capacity so that there’s no chance of overcharge. The reduction applies to batteries in all states of previous capacity, so if an older or heavily used battery was already depleting, the update could result in shorter overall capacity. A full capacity G10t should give 6 hours of play time wherein it used to provide 8 hours. Let me know if you have any further questions. Kind regards, Jason-Line 6 support
