Mobile Phones

Android ist ein von Google entwickeltes Betriebssystem, das derzeit von den meisten Handy-Herstellern verwendet wird. Es handelt sich um ein offenes Betriebssystem mit nahezu unbegrenzten Anpassungsmöglichkeiten. Einige Anpassungen können über die Grundeinstellungen vorgenommen werden, während andere jederzeit aus dem Google Play Store heruntergeladen werden können. Der Benutzer kann also nicht nur die grafische Benutzeroberfläche, sondern auch die Bedienung des Handys sehr einfach ändern. Die Schwäche von Android ist dann die höhere Anfälligkeit für Angriffe durch Schadsoftware. Eine ausführlichere Beschreibung der einzelnen Betriebssysteme sowie ihrer Vor- und Nachteile finden Sie in unserem Artikel Vergleich der mobilen Betriebssysteme.

Operational memory, or RAM, is a quickly accessible memory that stores the data being processed. In general, the larger the operating memory of the device, the faster it runs and handles more operations at once.

The display refresh rate indicates how many times per second the screen image is redrawn. A higher number means a smoother turnaround. The normal frequency is 60 Hz and you may notice a slight tearing on it when scrolling quickly. It does not occur at refresh rates of 90, 120 or more Hertz.

Electrical power input is the amount of power that flows from the socket or power supply. The output is always lower than the input. This is where the concept of perpetual motion comes into play, because there will always be some energy loss (thermal, motion or sound). This creates the difference between input power and output power.

Treble is a project aimed at making Android update times faster by separating part of the operating system from vendor implementation to a new vendor interface. Treble provides some of the updates (security patches, kernel, etc.) for the device by Google rather than from the Android OS framework. The second part of the update is provided by the device-specific original vendor (graphical superstructure of the user environment, vendor specific system applications, etc.)
