HikingSpecs Lab

The problem we exist for

Every GPS watch ships with a battery number measured the same way: room temperature, screen off, GPS on its laziest setting, sitting still. Then it gets sold to people heading into cold, wind, and continuous multi-band tracking, where that number does not hold. HikingSpecs Lab exists to calculate what is left once the real world gets involved, and to report the difference plainly.

One model, applied the same way to every watch

There are no opinions here and no sponsored picks. Every figure comes from one published model, Formula v1.0, applied to every device under the same fixed reference scenario. It estimates how much usable energy a battery delivers under cold, wind, continuous GPS, and cell aging, then calculates the hour the device goes dark. The same inputs, the same scenario, every watch. The full method is open at /methodology, and the formula is machine-readable at /formula/v1.0.json.

What we claim, and what we do not

The model is calibrated but not yet independently validated against measured field runtime, and the Lab says so openly on every relevant page. Where a hardware input is estimated rather than documented, it is labeled as such. Nothing is presented as more precise than it is. The point is not to flatter a brand or to alarm a buyer, but to give one honest planning number for the route that actually matters.
