Report sent with firmware version numbers. I am charging a USB battery pack from the same Anker usb charger and that is fine. It seems the Quest 2 is slow charging and not reaching 100%.
My Q2 charges and works just fine with v43 as it did with v42. Sounds like an issue on your end. You also mentioned charging the device with an Anker (assuming) quick charger. Anker's chargers are known to kill devices. I know I've lost a few to them, as did a good bit of people I know. It's Chinese junk. Also, if it is a quick charger, you never want to use one to charge any device that doesn't support fast charging (pretty sure Q2's don't), regardless how 'smart' the charger is or what the marketing for it claims.
