The Beeline expert told how to use a smartphone correctly in the heat

What to do to make the gadget survive the summer.

The Moscow region has been experiencing record-breaking hot weather 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 about the risks of non-compliance with these simple rules.

  1. Control the temperature of the screen, phone case and charger while charging, do not let the device stay in an overheated state for a long time.
  2. Charge your phone no more than 90%, do not use untested chargers: in the heat, they are at increased risk.
  3. When charging, ensure maximum heat exchange between the phone and the environment: take it out of bags, cases, pockets into the air. Place on metal surfaces whenever possible for better heat dissipation.
  4. Try to use the fast charge mode intermittently, no longer than 10-15 minutes each charge cycle. 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. Remove from direct sunlight (window sills, benches in public places, seats and holders under glass of cars, bicycles, scooters). Please be aware that the temperature of some elements in the vehicle interior can reach 60–90 ° C.
  7. Do not place your phone next to equipment that generates heat (microwave ovens, car panels, heaters).
  8. If it overheats, cool the phone 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 cases and covers) that impair heat dissipation from the phone case.
  9. You cannot cool the phone with shock drops (freezer, ice), you should also exclude direct contact with water. Water causes short circuits in circuits and deposits corrosion. Sudden changes in temperature can cause mechanical deformation of circuit elements or a battery and eventually lead to micro-damage to the components 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. Pay attention to the unusual operation of the smartphone in conjunction with the increased temperature of the case. These failures can be both reversible and irreversible.
  12. Try to limit your energy use. Large and long-term consumption currents heat up the circuits and the body of the device no less than when charging the device.

What you can do:

  • decrease screen brightness (for smartphones, this is the main consumption booster);
  • reduce the operating time with the screen on;
  • avoid long calls and internet sessions (longer than 15–20 minutes, such as watching movies, listening to music, audio and video conferencing).

The following devices are considered to be the most at risk:

  • non-branded batteries,
  • old batteries (over one and a half years old),
  • phone after a recent battery change,
  • a telephone of unknown origin that just got into your hands,
  • new phone out of the box.

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 (also applies to the charger);
  • the device displays charging errors, emits an audible alarm, turns off spontaneously;
  • charging does not work when heated;
  • deformation of the case or cover associated with an increase in the size of the battery (swelling);
  • freezes and abnormal behavior coincided with excessive heat.
