Too Afraid to Ask

State of health tells you how well a battery is working compared to when it was new. It's shown as a percentage, so if it's at 97%, it means the battery is still in good shape but has lost a little bit of its power.

State of health (SoH) is a measure of the current condition of a battery compared to its ideal or original state. It is expressed as a percentage and indicates how much capacity the battery has lost over time due to usage and aging.
