Hi - I wish my range was still 317. But it has dropped. Part of me charging to 100% was curiosity of what it would get to. It was at 288 and holding for 10 minutes about (even though it was charging at 20+ miles per hour - which would suggest adding about 3 miles of range). The battery visual was full green. I would bet that if I had checked the percentage it would have said 100% but I didn’t check so I could be wrong.
