As mentioned in the beginning, mobile phones are now an integral part of our lives and not just an accessory. With the advancements in internet services and digital media, our smartphones have turned into a virtual workspace and a place for communicating with friends and family. So there is a lot of important data stored on these devices at any given moment. If something happens to the phone, rendering you unable to access the data, it is a very serious problem.
If you simply press the power button, then it will run through the shutdown process. However, if you hold the power button down, then it will perform what is called a hard shut down. This will abruptly shut your computer down, closing any files and programs in the process. This is not a recommended way of shutting your system off, as it can result in data corruption, loss of data and even hardware failure.
