deep sleep with gpio button wake up - 6mA current?

[BootsSiR]

When I use the following code to put my LilyGo T-Display S3 into deep sleep, my meter is showing 6.4 mA of current draw using the onboard button as a GPIO wake up. I was expecting much less. Am I missing something?

// draws 6.42mA asleep and 147.7mA awake
void sleep() {
    if (!_isSleeping) {
        ESP_LOGI(TAG, "Going to sleep... night night");
        _isSleeping = true;

        // Configure GPIO button as wake-up source
        esp_sleep_enable_ext0_wakeup((gpio_num_t)PIN_BUTTON_2, 0); // 0 for active low (button press)
        
        gpio_set_pull_mode((gpio_num_t)PIN_BUTTON_2, GPIO_PULLUP_ONLY);

        // kill the LCD power and backlight
        gpio_set_direction((gpio_num_t)LCD_PIN_POWER, GPIO_MODE_OUTPUT);
        gpio_set_direction((gpio_num_t)LCD_PIN_BK_LIGHT, GPIO_MODE_OUTPUT);

        gpio_set_level((gpio_num_t)LCD_PIN_POWER, 0);
        gpio_set_level((gpio_num_t)LCD_PIN_BK_LIGHT, 0);

        // Enter deep sleep
        esp_deep_sleep_start();
    }
}

Look at the information I submitted, the screen needs to be set to sleep

@lewisxhe now drawing 263 µA in deep sleep. Much better! Thank you 👍
