I've also had charging issues with my HS70. It's always a guessing game what percentage the battery will be at after I unplug it. Sometimes it will be at 100%, but commonly it will be some seemingly random percentage below that. Sometimes it is 92% or 96% or 72% or anything else. For a very short time I thought I had figured it out. Originally I was turning the headset off and then plugging it in to charge. I decided to leave the headset on (while also leaving my computer on even though the USB ports do still provide power when the computer is off) so I could hear the "Battery Charging" and "Battery Complete" voice prompts. Twice in a row this method resulted in the iCUE showing 100% charge after unplugging. I thought this had solved it. Maybe the headset somehow better regulates charging when it is left on or maybe leaving my computer on meant the iCUE software could work some magic. However, earlier today I unplugged it (light was green, had been charging for hours) and it only showed 96%. Not that far off from 100, but I decided to plug it back in. Unplugged it a few hours later and the batter had gone DOWN to 88%. It started at 96%, I plugged it in, the light turned orange and then AFTER the light was green the battery had actually dropped to 88%. While plugged in. I also have tried plugging the headset into my Anker 5-port USB charger (that I use for my phone and smart watch) with equally mixed success. Honestly not really sure what to do at this point. I can still return it to the store I bought it from so I'm not convinced it is worth pursuing warranty work through Corsair. Also not sure if it is worth swapping it out for another one since other people are having this problem. Real pity because I love the HS70 in every other way.
