All batteries degrade and fail, inevitably and always.
Call us back when it’s below 80 and is not holding a charge for as long as is required for your typical use. It’s due for a battery replacement then; as the then-current health drops below ~80.
Otherwise, you’re just slightly past half-way through the lifetime of this battery.
And this health value is the current indication, and a value and a trend which may not predict the future lifetime of the battery, either for better or for worse.
