Basically the only thing that's keeping me from buying this.Thanks for the answer, but what I mean by battery life is how fast will battery wear down when a device will be connected to the AC almost all of the time.
Some kind of battery protection could be implemented, like keep charge it to 80% and let it discharge to 20% and again charge it to 80%.
I think it would prolong the life of the battery, keeping it at 100% and charge it continuosly while it is using is quite bad for lithium batteries AFAIK.
I mean it's not a very complicated thing to implement.
Fiio does it with their BTR5. USB mode ? No problem, charge on or off...
It's not exactly rocket engineering
