I'm curious to know why the Oculus Go behaves the way it does.
If I have it plugged in while it has a full charge and play Republique it doesn't lose any charge. But if I use the battery and plug it in when it's at around 20% the battery eventually drains to 0% which I can run for maybe 15 minutes and then the device turns off automatically without a heat warning. I imagine this is a software issue because the science doesn't make sense to me at all.
Maybe do a bit more research on lithium ion batteries. When they get down to low levels below about 25% (depends on pack specs) they can often discharge very quickly under load).
As a general rule of thumb, charge your Go to at least 80% before using it connected to your charger. Without it connected to your charger avoid discharging below 30%. After this let it cool down before charging it again and avoid using it until it is at least 80%, preferably 100%. Do this and your Go battery will last a long time.
