Nice surprise! Range increase after OTA update

[DadOfFive]

My J1.1 2022 4S CT just got an OTA update that included some tweaks to the battery management system. At 85% SoC, my range now says 242 miles (was around 220 before). Whether or not this translates to real world range improvement ¯\_(ツ)_/¯ but it’s nice to see that the J1.1 cars haven’t been completely forgotten.

I’ve noticed an increase in my range as well, but I doubt it‘s accurate. 237 miles at 70% for a J1.1 just doesn’t make sense mathematically unless my efficiency is over 3.6mi/kWh

Mine also improved. I’ve gotten as high as 280 driving normally, 270-275 including some freeway driving.

I've noticed another change lately: charging from 80% to 100% seems to be a bit faster. The announced time until fully charged is quite shorter than earlier.

Same here. Approved with 85% charge at 240..

The update occurred around July 3–4, 2026. The trips on July 6 and July 9 didn’t have the same start and end points, but efficiency did improve by about 0.2–0.3 mi/kWh on those drives.

Have you found documentation online about this update? I would like to learn more about what is changed.
