If I had knew this issue I would not have bought HS70 Pro, because that was exactly my fear, that the design would be bad regarding batteries and lifetime.
Wonder why Corsair dosent address this in an firmware update. Since I bought it, the firmware remains at v0.01 at iCue, guess we will never get any kind of updates.
I bought mine in march 23 2020, worked ok until now but since like 2 days ago I noticed it started to charge very slowly.
I will try to charge it from the wall, to see if it goes full battery, but I must say I used to see that green light every morning and now I see it no more.
