# Power modes

Flipper Zero has two operating modes: **Active** and **Sleep**. Each mode consumes power differently.

## Active mode

When Flipper Zero runs an application or establishes a connection, the device enters Active mode, which consumes power up to 30 mA with a backlight. With an active transceiver, power consumption can reach 400 mA, and even 2 A with an active transceiver and connected external module.

:::Iframe{iframeHeight="0" code="<div class=&#x22;sdcard flipper-callout&#x22;>&#xA;    <div class=&#x22;callout-header&#x22;>Use a high-quality microSD card for longer battery life</div>&#xA;    When the display backlight is on, Flipper Zero’s current consumption with a genuine branded microSD card is up to 30 mA. With a non-genuine microSD card, the overall current consumption may reach up to 50 mA leading to a shorter battery life of your device.&#xA;    <br />&#xA;    <br />&#xA;    If the battery of your Flipper Zero is draining fast, check the current consumption: <b>Main Menu -> Settings -> Power -> Battery Info</b>.&#xA;</div>"}

:::

## Sleep mode

When there are no running applications or connections established on your Flipper Zero, the device enters Sleep mode, which has a power consumption of around 1.5 mA.&#x20;

:::Iframe{iframeHeight="0" code="<div class=&#x22;info flipper-callout&#x22;>&#xA;    <div class=&#x22;callout-header&#x22;>Disable settings that prevent Sleep mode</div>&#xA;    To ensure Sleep mode works as expected, both Debug mode and the Listen UART feature must be disabled.&#xA;  <br>&#xA;  <br>&#xA;  To disable Debug  mode, go to <b>Main Menu → Settings → System</b>, select <b>Debug</b>, and set it to <b>OFF</b>.&#xA;  <br>&#xA;  <br> &#xA;  To disable the Listen UART feature, go to <b>Main Menu → Settings → Expansion Modules</b> and set <b>Listen UART</b> to <b>None</b>.&#xA;  </div>"}

:::

Two sleep modes are available for your Flipper Zero: **Default** and **Legacy**. Default sleep mode has a power consumption of around 1.5 mA, resulting in a longer battery life. However, you may experience device crashes while using this mode. Legacy sleep mode has a power consumption of 9 mA leading to shorter battery life but also providing more stability to your device.

You can switch to legacy sleep mode by going to **Main Menu -> Settings -> System** and setting **Sleep Method** to **Legacy**.

# Tips for maximizing battery performance

**Battery life** is the amount of time your Flipper Zero runs before it needs to be recharged. **Battery lifespan** is the amount of time your battery lasts until it needs to be replaced.

## Long battery life

- Update to the latest firmware version. -> [Update your Flipper Zero](https://docs.flipper.net/zero/basics/firmware-update) regularly since we constantly optimize the firmware and add new power-saving features.

- Optimize your settings. -> You can adjust parameters in the [Settings](https://docs.flipper.net/zero/basics/settings) application, such as Bluetooth, display, and system settings.

## Long battery lifespan

- Avoid extreme ambient temperatures. -> Flipper Zero is designed to operate within the temperature range of 0° to 40° C (32° to 104° F). Avoid exposing your device to ambient temperatures outside this specified range.

- Store the device half-charged when turned off for extended periods. -> Charge your Flipper Zero to around 50% before turning it off for a long period of time.
