Charged builds a battery history for each of your sensors every time rides sync. It can notify you when a battery is running low, and predicts how much ride time is remaining.

What's an ANT+ ID?
The number a bike computer shows for a sensor it pairs over ANT+. A smart trainer's power-match setting asks for it, and so do some gym screens.
Why is a sensor listed twice?
Many sensors connect over both ANT+ and Bluetooth, and some do two jobs, like a radar with a tail light. Your bike computer keeps a pairing for each.
Why do some sensors show status only?
Some sensors only report a status word instead of a charge percentage, and some bike computers only record the status even when a device reported its charge level. The words run New, Good, OK, Low, Critical. "New" is the top charge level, not a new battery. Some devices only report OK or Low. A sensor that wasn't connected during the ride has no reading.
What do * and Probably mean?
They mark something Charged worked out rather than read straight from the file: * on an ANT+ ID, Probably on a name. Tap the sensor to see how.
