Are we actually sure the device is unsafe this way? Doesn’t the battery provide in hardware protection against overheating/over current etc?

Pinephone battery uses a 3 kOhm NTC to monitor the temperature. Power management chip in Pinephone expects 10 kOhm variant by default.

This sounds like the battery itself has protection equipment already. Which seems required by law: https://batteryuniversity.com/learn/article/safety_circuits_for_modern_batteries. the Pinephone perfectly safe though the kernel should still deal with power management if only to prevent batteries from dying because of triggered safety hardware.


The battery itself is not protected again heat issues.


I think this is a valid point, but also…

Has this person ever heard of desktop linux? Do they have any understanding of what free software is? You choose what software you run on the phone, so you have to take responsibility and make sure you install software that is somewhat respected. The software is provided “as is” to protect the rights of the developers who are often not paid (or not paid much) for their efforts.

Sure, you might not be able to blame someone if there is a flaw, and flaws in the software might be more likely in some cases because there is less money being spent of security overall, but that’s really missing the point. In other phones you just have to trust the software, you can’t even check it or ask someone else to check that it is doing what it says it is.


He is a quite important contributor to the open-source and p-boot. In a following post he provided some (two) solutions for this problem. But it must be fixed properly and in upstream.

Community about running GNU/Linux on phones. Projects like Ubuntu Touch, Plasma Mobile, PostmarketOS, Mobian etc. Either on former Android phones or hardware like the PinePhone.
