Please fix accuracy of remaining charge. I have Whoop MG. 9% is NOT 3 days.
What you expected instead
Accurate time estimates.
Steps to reproduce
Strap log
Before you submit
I attached my exported NOOP .zip (not a screenshot of the Live screen). If my bug is a clearly reproducible UI issue I described exactly how to see it instead.
I attached or pasted a strap log above — or my bug is a clearly reproducible UI issue that doesn't need one (e.g. a typo, a button that does nothing) and I've described exactly how to see it.
I checked the Troubleshooting guide — especially "history syncs but no data" (most often the strap isn't banking history to flash; charge it to 100% and reconnect).
I checked the FAQ and — if I'm on a WHOOP 5.0 / MG — the 5.0/MG status page, and this isn't an already-known limit (e.g. SpO₂, or recovery/sleep on the 5/MG).
I've left out anything personal (strap serial, account email, raw export).
@ryanbr do we want to start working on a battery diagnostic test so users can test their own devices or do we want to keep it simple with a per reported percentage estimate
