Our mobile phones don’t like high temperatures, and summer is the season when its components can degrade the most if we don’t take certain precautions. Performance drops, battery degradation, maximum brightness limitations. We explain why you need to be extra careful during these months.

thermal throttling. In the latest Xataka analyzes, we pay special attention to how thermal throttling affects (throttling) to mobile phones. Especially on high-end mobiles, we were able to see how it did last year with the Qualcomm Snapdragon 8 Gen 1. they eventually lowered the performance when the phone starts measuring temperature.

A CPU test is all it takes to see how the phones are affected by the heat.

HE throttling It is a technique that has been used for years (in PCs as well) and reduces the performance of the device so that it does not continue to heat up. In the case of high-end phones, it is usually not overly noticeable, but if we have a mid-range terminal and it reaches insufficient operating temperature, we may begin to notice it. delay and important jerks.

Goodbye to bright peaks. One of the most energy-consuming elements in your phone is the screen. In recent years, brightness peaks have increased by more than or equal to 2,000 nits, which are simply gorgeous numbers, but certain not to end our autonomy. If the phone reaches a high temperature, it’s probably Decrease screen brightness.

Apple devices are a great example of this; iPhone is a device that can be easily controlled when it is hot, in the sun, and we want to see the screen in its direct light. If your phone isn’t able to reach its peak brightness in auto mode, that’s a good indication that it should be allowed to cool.

The battery is dying. The battery is one of the most sensitive components to heat. Scientific evidence suggests that heat is a critical factorhas a significant impact on performance. High temperature can cause premature aging and irreversible damage to the lithium battery.

In fact, one of the most ardent critics fast fees It has to do with the temperature spikes they produce. That’s why manufacturers are working on chargers that keep the heat in their heads to prevent some of this heat from being transmitted to the terminal. Likewise, if the phone is too hot, it’s possible that its charging slows down or that fast charging is directly disabled.

No good news for mobile signal either. While research published on this topic only sees a “weak positive correlation” between temperature and signal quality, there are manufacturers (like Apple) that put phone antennas in a low consumption state. This may cause the signal strength to drop as the device overheats.

operating temperatures. On the Apple side, it tells us it’s between the “acceptable” operating temperature for using an iPhone. Between 0 and 35ºC. Android giant Samsung confirms that this is the right strip. In fact, they state that “a temperature that is too high or too low can cause changes in the behavior of the device to regulate it.” Using a device in very hot conditions, to permanently shorten Battery life.”

Precautions to be taken to prevent the phone from getting hot

In the summer, it is especially easy for the device and battery to rise in temperature. exceeding 35 degrees, especially if we use it with a case or use it heavily. Therefore, it is important to consider some recommendations to prevent it from overheating.

Heavy use is not that heavy use. Playing the heaviest broadcast or recording 4K isn’t necessary for heavy use. Using the mobile phone during a car journey with Google Maps or Waze enabled, 5G connectivity and maximum brightness can actually cause the mobile phone to burn out. In fact, on extremely hot days (more than 40 degrees) the phone is easy to heat up even with light use (social networks, mail, browsing, etc.).

The cover is only on the street. A case is still your best ally if you want to protect your phone at all costs. However, if you are at home and the probability of falling is not high, we recommend that you uninstall. Even in the steam rooms on the most powerful mobile phones, the exercise of disintegration is especially complex in the summer.

Do not desperately close apps. One of the most common myths is that closing apps on our phone frees up resources: the exact opposite. Unless some processes are frozen (unlikely on current mobile phones), closing all apps is just fine. reopen processes such as automatic startup, consuming more resources, overheating of the battery and terminal.

Avoid apps that promise to cool your device. The same happens with apps that promise to lower the temperature of the mobile phone. It is absolutely impossible to achieve this by closing applications, and that is exactly what such applications do. Along the way, they exploit numerous ad-viewing opportunities and tend to stay in the background by curiously analyzing device data and consuming resources.

It’s not crazy to put your cell phone in the fridge, but not recommended. It may sound like a crazy internet tip, but no, since it doesn’t go below zero, if you put it in the fridge, your phone’s health (in terms of temperature) should be fine according to scientific evidence. Actually, out of curiosity, seeing the poor results offered by folding cell phones due to poor heat dissipation exercise, I tried to make a comparison with the cell phone in the refrigerator: the results skyrocketed.

The problem here is that it’s not all about temperature: our phone can suffer from moisture or the risk of liquid getting inside, so there won’t be a server suggesting you put the phone in the fridge to cool it.
