Details, but we'd also need to know what miles these % numbers corresponded to. As the battery degrades, I believe the miles/% reduces from 3.1mi/% to something less (and the available kWh goes down). (A degraded battery shows 100% charge when fully charged, AFAIK - though admittedly I don't KNOW this, others can comment. But it does NOT show 310 miles anymore...) We have no way of knowing from your pictures what the state of your battery is. It may be just fine; I'm just pointing out that we can't draw a conclusion from your stated data.
