What's the battery life of the Ledger Nano X?

Battery Capacity and Daily Usage

1. The Ledger Nano X is equipped with a 100 mAh lithium-polymer battery, designed to support both daily operations and extended storage periods. This capacity allows users to perform multiple transaction verifications and device startups without immediate recharging.

2. Under normal usage conditions—such as checking balances, signing transactions, and navigating menus—the device can last up to 8 hours on a single charge when Bluetooth is active. Turning off Bluetooth significantly extends this duration.

3. When Bluetooth is disabled and the device is used intermittently, battery life can extend beyond several days of standby time. Power consumption primarily depends on screen usage and how frequently the device connects to the Ledger Live app.

4. Charging the Ledger Nano X takes approximately 2 hours using the included USB-C cable. It draws power efficiently and reaches full charge without overheating, maintaining stable performance during the process.

Bluetooth Connectivity and Power Draw

1. One of the key features of the Ledger Nano X is its Bluetooth capability, enabling wireless interaction with mobile devices. However, keeping Bluetooth enabled increases power consumption noticeably.

2. During active Bluetooth sessions—like approving transactions or syncing with Ledger Live—the device consumes more energy compared to offline mode. Users engaging in frequent wireless operations should expect to recharge every few days.

3. Bluetooth can be toggled off through the device settings to conserve power. Disabling it turns the Nano X into a low-power hardware wallet similar to earlier models like the Nano S.

4. Firmware updates have optimized Bluetooth efficiency over time, reducing idle drain while maintaining secure pairing protocols with smartphones and tablets.

Long-Term Reliability and Battery Degradation

1. The internal battery is built to endure hundreds of charge cycles before any significant degradation occurs. Regular charging from 0% to 100% does not immediately impact performance due to protective circuitry.

2. Over extended ownership periods—typically two to three years—users may notice reduced battery retention, which is common for small-capacity batteries in compact electronics.

3. Unlike smartphones, the Ledger Nano X does not rely on constant connectivity, minimizing stress on the battery. Infrequent but consistent usage patterns help preserve overall battery health.

4. There is no user-replaceable battery; if degradation affects functionality, users must contact Ledger support for repair or replacement options under warranty.

Frequently Asked Questions

How long does it take to fully charge the Ledger Nano X?It takes about 2 hours to fully charge the Ledger Nano X using the provided USB-C cable. Charging speed remains consistent across different power sources, though slower outputs may extend the time slightly.

Can I use the Ledger Nano X while it’s charging?Yes, the device functions normally while connected to a power source. Transactions can be reviewed and signed during charging, with no interruption in security features or interface responsiveness.

Does the battery drain when the device is turned off?When powered off, the Ledger Nano X consumes negligible energy. Any measurable drain occurs only when the device is actively running, displaying information, or communicating via Bluetooth.

Is it safe to leave the Ledger Nano X plugged in overnight?Yes, the device includes overcharge protection. Once the battery reaches full capacity, charging stops automatically, making overnight charging safe and risk-free.
