Fast charging is a technology that allows you to charge your phone more efficiently. Whereas previously the smartphone needed three hours to charge 100%, today less than half the time for the same battery size is just enough.

A mobile phone is water resistant if it meets a certified level of durability that allows total immersion. When it comes to mobile phones, it is the specification of the IP67, IP68, or IP69 Ingress Protection rating.

A method of rendering LCD-display images. In this case, the image is formed by a thin film of transistors. A thin part of the display consists of small transistors that control individual picture points, or pixels. Unlike previous technologies, it has brought high image quality, high contrast, lower power consumption and smaller size. Today, the biggest advantage of TFT displays is the price. Compared with premium OLEDs, they also have a significantly longer life.

Bluetooth is the communication tool used by a huge amount of electronics. Learn how the frequency signal is generated and how it's used. In a simple overview of the different versions, we will show how Bluetooth has evolved and been refined. You can also learn something about the specifications and security of this communication standard.

A device that receives a GPS signal to determine and record a location. GPS modules can be found in car and motorcycle navigation systems, cyclocomputers, sporttesters and GPS locators.

LTE (Long Term Evolution) marks the next generation of mobile data networks. This is an intermediate step between 3G and 4G. Although manufacturers and operators sometimes mistakenly refer to it as 4G, it is not a full 4G network. That's for LTE Advanced. The maximum theoretical data transfer rate is up to 175Mbps for download and up to 57.6Mbps for sending data in one frequency band.

Accelerometers and G-Sensors are motion sensors that determine the tilt in space. The phone uses it to know which way it is being held, e.g. portrait, landscape or upside down.

Az Android a Google által kifejlesztett operációs rendszer, amelyet jelenleg a legtöbb mobiltelefon-gyártó használ. Ez egy nyílt operációs rendszer, amely gyakorlatilag korlátlan testreszabási lehetőségekkel rendelkezik. Egyes módosítások az alapbeállítások segítségével végezhetők el, míg más módosítások bármikor letölthetők a Google Play áruházból. A felhasználó így nagyon könnyen módosíthatja nemcsak a grafikus felületet, hanem a telefon kezelésének módját is. Az Android gyenge pontja a rosszindulatú támadásokra való nagyobb fogékonyság. Az egyes operációs rendszerek részletesebb leírása, előnyeik és hátrányaik a Mobil operációs rendszerek összehasonlítása című cikkben található.
