As you surely know, at colder temperatures and in frosty conditions, battery it bothers you in your portable devices. If you want to protect it, you can do it now a few simple steps, which will help him. What are they? We will look at this in our guide today.
Smartphone and frost
Why should you protect your smartphone from frost? It's simple, the answer is the battery. Currently, the most widely used lithium-ion cells use a liquid electrolyte consisting of an organic solvent and a conductive lithium salt.
Due to their composition, these batteries are easily affected by external temperatures. When exposed to cold for a long time, the phone may turn off even though it remains in the battery 20% more energy.
And devices left for extended periods of time in extremely low temperatures can be susceptible to permanent damage, especially if they are in standby or sleep mode. Low temperatures increase internal resistance and decrease capacitance.
In practice, this means that, similar to other liquids or liquid-based substances, if it is cold, the molecules shrink and this reduces performance. However, this reaction happens directly in your smartphones, when used in freezing temperatures.
How to protect yourself?
A very effective solution that anyone can do is to carry the phone as close as possible to the body (for example, in the inner pocket of a jacket or coat). The temperature of the human body is approximately 37 °C. This means that you yourself are the natural source of heat, thanks to which your smartphone will not cool down to such a low level, compared to carrying it in a backpack.
Do you have a job where you often make phone calls? Or are frequent phone calls part of your free time? In that case, it is definitely important to consider purchasing a wireless one hands-free kits.
This accessory can be purchased for 10 € and will help you communicate in such a way that your smartphone is dry and warm. A slightly more expensive solution can be a fitness bracelet or smart watch.
As for the physical protection of your device, the solution can be the use of a cover or protective case. This may or may not be adapted to cold temperatures, but it will create a layer of insulation from outside influences. The phone will not be exposed to frost directly, and the case will retain part of the heat generated during its use. A suitably chosen case can also protect you against falls.
These are the little things you can learn
If you are already going to cold or frosty weather, you should definitely not set out with an almost empty battery. As we mentioned above, harsh conditions can shorten battery life, so make sure you charge your device. In addition to charging at home or in the office, you can also charge the battery on the go. Today, you can get quality power banks with fast charging for a few tens of euros.
Imagine a model situation: Your smartphone has been in freezing conditions for a long time and does not want to turn on again. Try not to panic. If the smartphone turns off due to too low or too high ambient temperatures, this is a defense mechanism. It ensures operation under optimal conditions. When returning from a cold environment, simply let the device warm up slowly and only then start it.
Smartphones usually contain IPS LCD or AMOLED panel. And it is the first named that can cause delayed reactions to touches, blurring of the image or the so-called "ghosts". Sometimes you can also notice zero reaction between the frozen display and the cold thumb. The solution is simple - let the smartphone warm up a little. AMOLED display does not have this problem.
The so-called silent killer of electronics is condensation (transformation of gaseous substances into liquids). This phenomenon can occur precisely with a sudden change in temperature. For example, users with glasses, where dioptric lenses react very similarly, may know their own about this. Even in this case, continuous heating of the device to room temperature works.
