Safe mode shows how quickly the system works, unloaded by excess applications, widgets, launches and other visual elements. In this mode, the battery charge lasts much longer, so when the phone needs at least the main functions, and the batteries are still far from charging, the transition to a safe mode will allow you to stretch for some more time. For demanding users, this mode can become a tool for selecting the most optimal applications for a more speed operation of the OS. Also, a safe mode is useful in emergency cases if the smartphone for some reason began to slow down or hang at the most inopportune moment and it is necessary to make an urgent call or send a message.
