The experts told how to properly use a smartphone in the heatwave

The world has been experiencing record-breaking hot weather (heatwaves) for several weeks now. During this period, it is not easy not only for people, but also for gadgets. Alexey Vereshchagin, head of the department for analysis of subscriber equipment and support for the development of the Beeline network, shared some advice on the correct and safe operation of smartphones in hot weather and told what risks non-observance of these simple rules can carry.

1. While charging, we control the temperature of the screen, phone case and charger, do not allow the device to be in an overheated state for a long time.

2. We charge the phone no higher than 90%, do not use untested chargers: in the heat they fall into a high-risk group.

3. During charging, we ensure the maximum heat exchange of the phone with the environment: we take it out of bags, cases, pockets into the air, if possible, put it on metal surfaces for better heat dissipation.

4. We try to use the “fast charging” mode intermittently, no longer than 10-15 minutes each. Many smartphones are equipped with such a mode, but you need to understand that it implies extreme power loads on the battery, cable and charger.

5. In any case, it is better to divide the charging process into short series, allowing the device to rest and temporarily stabilize.

6. We remove from direct sunlight (window sills, benches in public places, seats and holders under the glass of cars, bicycles, scooters). Remember that the temperature of some elements in the car interior can reach 60-90 degrees.

7. Do not put your phone next to equipment that generates heat (microwave ovens, car panels, heaters)

8. When overheating, cool it down as quickly as possible: disconnect it from the charger, turn it off, put it in the shade, under ventilation, remove accessories that do not conduct heat well (plastic covers and covers) that impair the heat dissipation from the phone case.

9. Do not cool with shock drops (freezer, ice) and exclude direct contact with water. Water causes short circuits in circuits and deposits corrosion. Sudden temperature changes can cause mechanical deformation of circuit elements or a battery and eventually lead to micro-damage to the component elements of the device, as well as special coatings.

10. Pay attention to the messages on the phone screen about charging errors, overtemperature (some devices provide this function).

11. We draw your attention to the unusual operation of the smartphone in conjunction with the increased temperature of the case. These failures can be both reversible and, unfortunately, irreversible.

12. We try to limit energy consumption. Large and long-term consumption currents heat up the circuits and the body of the device no less than when charging the device. What do we do:

  • reduce the screen brightness (for smartphones, this is the main consumption booster)
  • reduce the time with the screen on
  • we avoid long calls and internet sessions (longer than 15-20 minutes, for example, movies, music, audio-video conferences)

13. In my opinion, the following devices can be considered the most at risk groups:

  • non-branded batteries,
  • old batteries (over 1.5 years old),
  • phone after a recent battery change,
  • phone of unknown origin, which just fell into your hands.
  • new phone out of the box.

14. Signs requiring special attention, in which it is necessary to urgently cool the device or send it to a specialist for diagnostics, stop operation until the effect is eliminated:

  • some elements of the apparatus are scorching hot (the same applies to the charger)
  • the device displays charging errors, emits a sound alarm, turns off spontaneously
  • charging does not work when heating
  • deformation of the case / cover due to an increase in the size of the battery (swelling)
  • freezes and abnormal behavior coinciding with excessive heat.
