Battery capacity test on my 2.75 year old Mojo used as a portable stack:
- Blue for 1 hour 56 minutes.
- Green for 2 hours 46 minutes.
- Yellow for 3 hours 43 minutes.
- Red for 49 minutes.
- Flashing red for 15 minutes.
Full charge to shutoff is 9.5 hours. Purchased March 2016 with a battery manufacture date in 2015. I believe that is a lot closer to typical performance experienced by most owners than your experience. Capacity was determined in a continuous use playing FLAC files. I did this test because I had observed some slight swelling in the battery of my other Mojo purchased two months earlier than the tested unit and used as my desktop DAC plugged in 24/7 so I bought new batteries for both of them from a Chord dealer and decided to see if there was any reason to replace the portable unit’s battery. Guess not yet. Cost to replace was about $65 each.
