Technology experts recommend that you always buy a protective case for your cell phone, as this element can save you from suffering multiple accidents that can lead to irreparable damage to your device.
Once you put the case on the phone, it practically stays there the whole time and is only removed or moved in case a technical service is needed on the phone.
What very few know is that the recommendation given by experts on the subject is that you have to remove the cell phone case when you charge your battery.
Previously, cell phones were charged at a power of 10 to 18 W and the case did not affect this, since the current stored in the battery did not generate a high enough temperature difference to activate the protection mechanisms.
But currently, both high and low temperatures do affect the performance and life of the cell phone. That is why batteries and charging systems have safety mechanisms that reduce the charging rate in order to prevent the temperature from exceeding a certain range and to prevent serious damage to the phone.
Generally, lithium batteries, which are the most used for cell phones, have a stable behavior at temperatures below 30 ºC and a very low degradation up to 35-40 ºC. But once that range is exceeded, the batteries start to wear down considerably.
In the event that the cell phone overheats during charging, crystallization of the electrodes occurs, which leads to a gradual loss of capacity over time. This process is not automatic or direct, but gradual, and over time we will notice how the autonomy of the phone is reduced.
This situation also affects other cell phone components, since during charging, the entire terminal heats up due to the increase in battery temperature. This can lead to premature aging of the internal electronics.
So to avoid these situations, it is advisable to remove the case from your cell phone while charging it. Doing so increases the surface area for heat dissipation, which can be beneficial in terms of preserving the long-term durability and performance of your device.
