Screen. Problems related to this are cracks and chips formation (due to falls), violation of the sensor’s reaction, burning of pixels, peeling the screen, yellow spots and strips, moisture.
Charging connector. The two main causes of failure are pollution and mechanical exposure. If the smartphone supports wireless charging, it is better to use.
Mechanical buttons. They get stuck in time, stop clicking, sometimes even fall.
Microphones and speakers. Over time, dust may accumulate, so they should be cleaned. It is also dangerous to enter into microphones and moisture dynamics.
Battery. To extend the service life, do not empty the smartphone at 0% – it is better to put it in 20-30% for charging. Also, especially at night, do not hold on constant charging. Try not to use the device during charge, do not play at the temperature in challenging games, buy only original or certified charger.
