Socks disconnect after charging

This is a hardware behaviour, not an app bug — and it confuses everyone the first time it happens.

What's actually going on

When you plug the battery into its charger, the battery powers itself off to charge safely. The Bluetooth radio inside the battery turns off with it. Your phone sees the connection drop because the device literally went away.

When you unplug the battery, it does not turn itself back on automatically. That's by design — it saves power if you charged the battery overnight and aren't going to use it right away.

The one-step fix

After unplugging, press the power button on the battery once. The LED comes back on, the battery starts broadcasting over Bluetooth again, and the WARMWORLD app re-pairs automatically (you may need to re-open the app from the app switcher).

That's it. No need to "forget" the device, no re-pairing dance, no factory reset.
