Battery level mismatch?

Here's a previous post that coincides with @ScruffR's explanation above :

State of Charge Values

I believe the Device Vitals assume that the default Li-Po termination voltage of 4.112 V is used. The Fuel Gauge reports the actual SOC depending on the voltage when sampled. Here’s an example for a Boron being recharged by a small Solar Panel this morning. The Boron’s PMIC setting setChargeVoltage(4208) is used, instead of the 4.112 V (default). Note: be sure to monitor the enclosure temperature when charging to 4.208 V. Fuel Gauge reports 92% SOC @ 4.14V. This is the actual condition, re…
