E7 - Ledger Nano™ X battery conditioning
The Ledger Nano™ X battery needs occasional conditioning to perform best. Normally, this conditioning happens every time you plug in your Ledger device.
However, after weeks or months of inactivity, you might need to help the battery condition properly. It’s like a car battery that has been stored in the cold for a while: a few minutes of care will mean years of reliable service.
If you see one of these messages, condition the internal Ledger battery so that it can charge properly.

Condition the battery
Connect Ledger Nano X to your computer or a USB charger, and hold the Ledger in your hands for a few minutes.
You can use the Ledger while you are holding it. The warmth from your hands will gradually bring the active battery back into condition. Keep the Ledger plugged in during conditioning.
The conditioning might take up to 5 minutes. The battery is back in condition when you see the charging icon on the Secure Screen
