After a week of driving, I had a charge go to 311, but it wasn't quite 100%. The phone app showed the power from my 14-50 had dropped from 32 amps to 18 to 12 over about 15 minutes, so it was probably 99.9% at that point. I had to go to work and couldn't wait for it to finish. My typical 90% charge gives me 282 miles.
