@TheTrench said in Guide to charge limiting your Fairphone 5: a mere 30W at 4.2V puts us far over the 6A point anyway the actual voltage limit according to the official spec (that one from Fairphone since we don't have anything more specific) is 4.5 V, so loading at 6A should get us 27W instead of the advertised 30. I'd say that from a business having successfully sold a phone with a screen said to be 6.46" hence 16.4cm while the phone itself (screen and border) measures 16cm it would not be particularly surprising. Unless the official charger from Fairphone, as advertised, loads the battery with a voltage exceeding Fairphone specs. I'm certainly not qualified to appreciate the risks.

@kugiigi Can you give the exact code of a program that will return the dpi? Note that I'm trying to scale a non-Qt application, so I can use a secondary qt utility to get the screen density, but nothing more. What I have tried that does not give good results is: #include <QGuiApplication> #include <QScreen> #include <QDebug> #include <iostream> using namespace std; int main(int argc, char *argv[]) { QGuiApplication app(argc, argv); QScreen *screen = QGuiApplication::primaryScreen(); qreal dpi = screen->logicalDotsPerInch(); // Moyenne approximative cout << dpi <<endl; return 0; }

@TheTrench It's 20.04 OTA-10. 24.04 is not supported (yet, I hope) on this device.
