History and battery runway · Pro
Today's health is a reading. The trend is the answer.
Keep a per-device record for years, see the wear rate, and forecast when a Mac battery is likely to reach 80% health.
Battery runway
Put a date beside the decline.
Once there is enough history, WhatBattery fits a trend through the Mac's recorded health and estimates when it may reach 80%, the point Apple uses as a service reference.
It also reports the recent wear rate and flags when the battery begins ageing faster than its own established pattern.
- No forecast until there is enough evidence
- Projected 80% date and time remaining
- Recent wear rate in plain language
- Faster-than-trend warning
Two kinds of history
Inspect the session. Keep the lifetime record.
Dense telemetry helps explain what happened during a charge or drain. Sparse monthly health records show the slower wear story across every device.
Health History
Keep one durable record per device per day, rolled into monthly health and cycle summaries for Macs, iPhones, and iPads.
Reports and export
Keep the evidence when the battery matters.
Turn the current reading and lifetime summary into a one-page PDF or printout for a warranty claim, a Genius Bar visit, or a resale listing.
For deeper analysis, export recorded samples as CSV or JSON. Health history can also be backed up and restored.
- One-page PDF and print report
- CSV and JSON sample export
- Long-term health backup and restore
Stop guessing from one battery-health snapshot.
History, runway, reports, and export are included in WhatBattery Pro.
