Sounds more like low mileage along with maintaining a high SOC in very warm weather.
Nope that's not it, I too have a 2016 Leaf SV with a bad battery that's degrading really fast, I already lost my first bar too and I live in a cool climate. My friend has a 2013 Leaf with almost 60k miles and still has all 12 bars! He lives in my area too and he doesn't baby his battery either.
Another Minnesotan here. Adding some initial stats to this thread:
'13 Leaf SV (Leased) - Leased 34 months. Drove 41K miles. All 12 bars intact when returned car. Mostly charged to 80% between midnight and 5a.
'16 Leaf SV (Purchased - Manufactured 12/15) . Typical charging pattern is to try and charge to 75-90%. Charging typically happens between midnight and 5a.
Date Ahr SOH V Hx ODO QC L1/L2 SOC
11/10/2016 74.49 93% 388.84 88.41 9769 3 350 87.70%
11/26/2017 70.85 89% 345.54 83.71 24414 7 1198 30.30%
The 11/10/2016 was actually a test for a friend. He wanted to ensure he could get a good read before testing used Leafs.
The 11/26/2017 reading is my test to make sure I could get the readings on my phone.
Pretty happy that in over a year my SOH only dropped 4%.
On Tuesday I plan on charging the car to 100% SOC and taking another set of readings which I will report back into the thread.
