Trezor Safe 7 battery
The Trezor Safe 7 features a LiFePO₄ (Lithium Iron Phosphate) battery.
Why LiFePO₄?
Most devices use lithium-ion batteries, which wear out faster and can overheat.
The LiFePO₄ battery powering Trezor Safe 7 is safer, lasts longer, can be fully discharged without harm, and stores well over time.
This means your device remains reliable even if left unused or uncharged for long periods.
Wireless and magnetic charging
Trezor Safe 7 supports Qi2-compatible wireless charging.
Built-in magnets ensure the device attaches securely to the charging pad every time, providing a stable and simple way to power up.
Best practices
The Trezor Safe 7 is designed to be turned off when not in use. Leaving it on continuously will quickly drain the battery.
A few simple habits can help extend the lifespan of your battery:
- Turn the device off when you’re not using it.
- Lower the screen brightness to save power.
- Don’t keep it plugged in all the time.
- Charge when needed, let it run down between charges.
- Use and store it within safe temperature ranges.
- Keep it away from water, fire, or any other extreme conditions.
