How ChargeLog works
The instrument, explained part by part: what gets recorded when you plug in, how a curve becomes phases, where the estimates come from, and what stays on your phone — which is everything.
ChargeLog is in beta, so this handbook is short and it will change. What is here is held to the same rule as the app: every sentence is checked against the code before it ships, and re-audited as the app changes. Last audit: September 2026.
-
Recording
What happens when you plug in: the recording service, what every sample carries, and the one quiet notification.
-
The four phases
Starting up, charging, topping off, full — how ChargeLog segments a charging session's power curve into phases, and what it refuses to name.
-
Estimates & learning
How ChargeLog builds charge-time estimates from your own sessions — and why it refuses to print a number it cannot stand behind.
-
Battery helpers
Keep a floor, Charged by a time, Get me to a time — reminders that plan charging around your day, each off until you turn it on.
-
Your data
Where ChargeLog sessions are stored, what you can export, delete, and sync from your watch — and why nothing leaves your phone.
