After i charge to 100% and leave it 'off' for one-two days - i find my DX80 with 70-80% and need to charge it again.
I tested how long this dap out of the box can play flac with my UE900 - 10.5 hours. Now its only 7 hours. 3 months of use.
Maybe this is due to using DX80 as a PC DAC, because of continuous charging from USB?
Can battery capacity be reduced as a consequence of continous charging in theory?
Not specific to the DX80, but any device which has a lithium-ion or lithium-polymer battery (which the DX80 has): http://www.popularmechanics.com/technology/gadgets/how-to/a7432/why-your-gadgets-batteries-degrade-over-time-6705747/. In short, continuous charging probably doesn't help, but these kind of batteries degrade over time anyway.
