Depending on the Linux distribution used on a PinePhone, the default settings may differ. It may be advised to lower the settings (i.e. the thermal trip point temperatures) to prevent the phone components from being damaged by excessive heat.

			Current CPU temperature can be displayed using the following command:

	cat /sys/class/thermal/thermal_zone0/temp		cat /sys/class/thermal/thermal_zone0/temp

	To ~~retrieve~~ the thermal ~~zone~~ types and trip ~~points type~~:		The unit for all numeric values is millidegree Celsius. To read the thermal trip point types and current trip point temperatures, use the following:

	grep . /sys/class/thermal/thermal_zone0/trip_point_*_temp		grep . /sys/class/thermal/thermal_zone0/trip_point_*_temp
	grep . /sys/class/thermal/thermal_zone0/trip_point_*_type		grep . /sys/class/thermal/thermal_zone0/trip_point_*_type

The possible names and associated meanings for the trip point types are the following:

			* "active" – a trip point to enable active cooling
			* "passive" – a trip point to enable passive cooling
			* "hot" – a trip point to notify emergency
			* "critical" – hardware not reliable

			The values for the trip point temperatures can be lowered individually, but make sure the trip points have the correct value for their corresponding trip type, e.g. '''don't''' simply swap the values for the first and the second trip point. '''Make sure not to set values higher than 110000''' (i.e. 110 degrees Celsius, which is the default value) for the third threshold, as it may cause damage to the phone. Use the following commands:

	~~{{warning\|Setting wrong values in the Thermal Sysfs driver poses a risk, the instructions are directed towards expert-level users and developers!}}~~		echo 55000 > /sys/class/thermal/thermal_zone0/trip_point_0_temp # passive
			echo 75000 > /sys/class/thermal/thermal_zone0/trip_point_1_temp # hot
			echo 100000 > /sys/class/thermal/thermal_zone0/trip_point_2_temp # critical

	~~echo 65000 > /sys/class/thermal/thermal_zone0/trip_point_0_temp~~		Further information can be found in these documents from the Linux kenel source:
