158 miles of range on 2017 bolt?

I am super excited to have purchased a used 2017 bolt EV with 70k miles on it, however I am a bit concerned now that I have been able to charge it fully.

The range is currently 158 mi at a 95% charge. It is a nice 60 degrees Fahrenheit outside and all tires are at 42 psi. It will not charge past 95% because of the recall software update but that should only take ~12 miles off the full range.

Now to be fair I have given a few test drives to friends and family to demonstrate the powerful torque of EV’s and I live in a hilly area, but can that really account for 80 miles of lost range? I expected some battery degradation at 70k miles, but at 158 miles of range on a full charge should I be concerned?

Any feedback or tips are much appreciated.
