To prevent your smartwatch and Apple Watch from overheating

Smartwatches and the Apple Watch can overheat as they are frequently exposed to sunlight, making them more susceptible to overheating issues when we’re at the beach, when we’re driving a car, or while we’re waiting in the sun.

There are several tips for prevent your smartwatch or Apple Watch from getting too hotto be followed as soon as we perceive that the temperature is becoming too high on our wrist.

1) Operating temperature of smartwatches

Even though they are designed to be placed on the wrist smartwatches are particularly delicate from a temperature point of view.

Virtually all models on the market are designed to operate with operating temperatures between 0 and 35 °C; a value of 35 degrees can be considered a value that can easily be exceeded in summer, particularly in July and August.

The only smartwatch designed to withstand higher temperatures is theApple Watch Ultrawhich has a range of operating temperature between -20 to 55 °C.

The temperature ranges also change during the charging process, which in turn generates heat and lowers the tolerance thresholds for smartwatches: even in this case it is not advisable to exceed 35 degrees while charging is in progress, even if we have among the hands an Apple Watch Ultra.

2) Tips to avoid overheating

To avoid overheating on smartwatches we can follow some simple tips that can be applied to any wearable device:

• we avoid exposing the smartwatch screen to direct sunlight;
• we don’t leave the smartwatch resting on the dashboard of the parked car;
• we don’t leave the smartwatch in front of a window exposed to the sun;
• we avoid placing the smartwatch charger near windows or heat sources;
• we turn off the Always-on function of the smartwatch (if possible) when we have to spend many hours in the sun;
• we turn off the smartwatch completely when we are on the beach or have to work outdoors in summer;
• let’s avoid cooking with the smartwatch on our wrist, especially in summer;
• we only use the fitness tracking functions at dawn and dusk, avoiding the middle of a summer day;
• if we use theApple Watch Ultra for divinglet’s make sure that the water we immerse ourselves in has a temperature between 0 and 40 °C;
• we only charge the smartwatch at night.

By following these simple tips we will avoid most smartwatch overheating and we will reduce damage to the battery (the component most sensitive to heat) and other hardware components.

3) Use only original chargers

Often Smartwatch overheating is caused by using non-original wireless chargerswhich can easily bring the device to operating temperatures that are too high or outside the ranges foreseen by the manufacturer.

Below we have collected the original chargers for the main smartwatches sold, namely Apple Watch and Samsung Galaxy Watch:

• Magnetic Apple Dock for charging Apple Watch
• Samsung Fast Wireless Charger

Other chargers for Chinese smartwatches can be viewed on Amazon by entering the name of the smartwatch in our possession and opening the link to the manufacturer’s store.

4) The smartwatch is overheated: what to do?

Has your smartwatch now overheated and shows a thermometer icon, freezes or no longer opens installed functions and apps? This is the signal that alerts us to a temperature problem: it is better to stop and immediately put the smartwatch in the cool or in the shade, removing it from our wrist.

Sometimes a few minutes of rest or shade may be enough to bring the temperature down enough to resume correct functioning; in other cases we will have to turn off the smartwatch in order to get rid of the accumulated heat.

In our small way we can speed up the cooling process of the smartwatch turning off your phone’s Bluetooth to which it is associated, so as to prevent the arrival of new notifications; It can also help a lot by deactivating the smartwatch’s GPS, restarting it or turning off alarms and sound alerts for at least 15 minutes.

Conclusions

The summer heat or accidental exposure to high temperatures (for example in the kitchen or in a sauna) can be very harmful to the health of our smartwatch, which has very precise operating temperatures that must be respected on every occasion to avoid fires and explosions of lithium batteries.

The advice we can give you is to use an economical smartband like the Xiaomi Mi Band when we are at the seaside or under the sun: this small device handles high temperatures better, thus being able to leave the smartwatch at home.
