Re: Noise Cancelling 700 Firmware Update - Reduced Battery Life Announcement
I got all the firmware updates through 1.7.0 and the latest didn't fix the battery issue for me. I reverted back to 1.3.1 which did fix the problem and got "full battery" and 18 hrs and 29 min, which is probably expected given the age of my headset and the amount of use it gets. I empirically confirmed that the usage time was also extended on 1.3.1
Afterwards, I charged overnight on 1.3.1, updated to 1.7.0, and run the battery down again. Same amount of usage time. Charged to full and it still said "battery full" and showed 18 hrs and 29 min.
This method is the way to go if you're still having battery announcement problems.
