My 30kwh 2017 Leaf S had the battery module reprogrammed last summer to fix the "incorrect" low readings of SOH. I noticed that the GOM reads higher on a full battery, and SOH% drop seems slightly slower.
However, once last fall, I thought I'd noticed the SOH dropping like a stone when the battery is more depleted. I experienced that today.
I had SOC of 43% (on the dash, not leafspy), with GOM 41; then drove 21 miles on the freeway (55 to 65 mph). The SOC dropped to 8%, a drop of 35% over 21 miles, for a drop of 1.67% per mile driven. I've seen SOC% drop by 1.0 to 1.25% per mile driven, but pretty confident that 1.67% is unusual.
I am suspicious that my SOC is not dropping linearly from 100 down to zero. It seems as though SOG% decline speeds up as SOC drops.
**EDITED to call it SOC, not SOH **
