LED Indicator Colors

The phone is equipped with an indicator light that utilizes a spectrum of light-emitting diodes (LEDs) to produce various colors and patterns. Each color or pattern is designed to convey specific notifications and alerts, providing users with clear and immediate visual cues regarding the status of their device.

Boot-up

These are the colors and patterns used during boot-up to indicate which the state of tasks or error messages. The table below explains the meaning of these colors.

Color

Description

Red

The phone is charging.

Red (flashing)

There is a problem with charging.
See below.

Green

The U-Boot bootloader has started running.

Green (flashing)

A boot-loop persists in the bootloader.
See below.

Yellow (red/green)

The bootloader has started the kernel but there is insufficient power to continue.
See below.

Blue (flashing)

Indicates a notification message in the notification tray.
See Status LED.

Once the phone has started the operating system, the battery status is shown on the lock screen. When the screen is unlocked, the battery status is shown in the status line at the top of the screen.

Red

The device state of charge is represented by a red notification LED.

Resolving charging issues

Solid red

A nominal charging state is represented by a solid red indicator light. This is expected behavior while charging.

Half-second flashes once per second

If the red indicator light flashes red for a half-second once per second, a charging error has occurred and the charging process has been paused by the charge controller.

Before proceeding, verify that the battery is properly inserted into the device, then check the indicator light again.

Using the OEM charger and cable

If you are using the supplied charger or the problem persists when using the supplied charger then the problem could be that the battery is becoming too warm. The charge controller will pause charging when the battery temperature exceeds a threshold that is slightly above 40°C. Launch the Usage application, then select the Thermal tab to check the temperature reported for the sensor named bq25890-charger. If the reported temperature is too high, then if the ambient temperature is likely too high; try moving the charger and phone to a cooler location.

NOT using the OEM charger and cable

If you are not using the AC adapter and power cable that came with your phone:

  1. Disconnect the charger that you are using

  2. Wait until the red light stops flashing and goes out

  3. Wait 20 minutes

  4. Try using the OEM charger

Other possible issues

Other possible reasons that charging may pause are that the battery is missing or faulty i.e. charging has encountered an error of some kind.

Note that there is another flashing red signal viz. very short blinks about every 10 seconds. This means that the BQ25895 itself got warm, which would be normal under prolonged intensive use. The BQ25895 is a battery charge management chip from Texas Instruments (TI).

If the above does not resolve the issue, contact Purism support for further guidance.

Green

A flashing green light is a symptom of the bootloader starting followed by a reset as a result of insufficient power. This is usually the result of a battery charging issue. Follow the steps below to work around the problem:

  1. Hold down the Volume Up button for 5 seconds to enable trickle-charging.

  2. Once the light stops flashing, unplug then replug the power supply while still holding the Volume Up button.

  3. Release the Volume Up button and allow the battery to charge for an hour or more.

  4. Unplug the USB cable from the phone.

  5. Hold down the power button for 18 seconds.

  6. The phone should power on and the indicator light should appear green.

  7. Plug in the USB charging cable.

If the above steps do not help, try the recharging procedure for your phone:

Yellow

If the light is yellow, the bootloader is attemoting to load the kernel but has already determined that there is insufficient power to succeed for one of the following reasons:

  • The battery voltage is low and the USB-C cable was not plugged in prior to the bootloader running the USB power check.

  • The battery voltage is low and the USB charging current is low.

  • The battery voltage is zero and the USB current is too low.

Try disabling the modem and WLAN by pushing their kill switches in the down positions, towards the center of the phone.
