In winter, we are often faced with the fact that the batteries of their smartphones begin to quickly discharge in the cold. Or that the devices completely stop working at sub-zero temperatures.
Let’s Figure Out Why This Happens and How You Can Deal With It
Technology has advanced greatly over the past decade. A smartphone ten years ago did not have half the functionality that modern models have. Every year we get more powerful processors, better cameras, more advanced software. But there is one aspect that has not changed for many years. And these are batteries.
At the same time, smartphones themselves are becoming more and more power-hungry. It requires increasing battery capacity. In addition, the transition to 5G networks will have an even greater impact on the autonomy of devices. Unless radically new battery technology emerges soon, smartphone makers will have to use even larger batteries, which will lead to thicker cases – the larger the battery capacity, the larger its size. Nowadays, no one will be surprised by a smartphone with a 5000 mAh battery, although a few years ago they were very rare.
If your smartphone battery discharges due to the cold while playing lightning roulette in india at the online casino, consider keeping it warm with a battery pack or simply indulge in some offline gaming until it warms up.
What’s Inside the Battery
Unfortunately, modern batteries are not designed for harsh winters, because sub-zero temperatures are contraindicated for them. Almost all smartphone manufacturers use lithium-ion batteries, which are recommended for use at temperatures between 0 and 25 degrees. There are also lithium polymer batteries that can withstand temperatures down to -20, but this technology is much more expensive, so it is rarely found in smartphones.
The operating principle of lithium-ion batteries is to move ions between the anode and cathode within an electrolyte. During operation at the recommended temperatures, this process occurs as normal. However, at negative temperatures it is disrupted due to the freezing of the electrolyte, due to which the speed of ion movement is significantly reduced. This leads to the fact that the battery power is not enough to power the smartphone. In cold weather, batteries can behave unpredictably: users can see how the battery charge begins to melt before their eyes, but more often than not, all smartphones simply turn off.
The rate at which the battery freezes is also affected by the materials of the smartphone case. The worst thing when working in the cold is metal – it has high thermal conductivity, so it freezes quickly, thereby quickly freezing the insides of the smartphone. The situation is slightly better with glass cases, but most often they have a metal frame, so this option is also not for working in the cold. The plastic cases of cheap smartphones have the lowest thermal conductivity, so they can work much longer at temperatures below zero.
In modern realities, the situation when a user is left without access to a smartphone seems catastrophic. It gets even worse when you don’t have a charger with you.
What to Do to Avoid Ending Up In This Situation
Do not carry smartphones in bags and briefcases – they will definitely freeze there, and there is a high probability of taking a switched-off smartphone out of the bag;
Do not use smartphones in the cold for more than 10 minutes. And if you urgently need to talk on the phone or enter into correspondence, then it’s better to go to some heated room, for example, to the nearest store. In 10 minutes the battery will not have time to completely freeze, and you will not be left without communication.
If you have a short jacket or coat, then it is also better not to carry a smartphone in your jeans pocket. Yes, the device will be heated by body heat, but on the other hand it will be affected by sub-zero temperatures. It is best to carry devices in the inner pocket of your jacket – they will definitely be warm there.
But what to do if the smartphone has already turned off? Most often, this does not mean that the battery is completely discharged from the cold. Just warm up your smartphone. But you should not do this with a battery or a hairdryer – sudden changes in temperature can lead to the formation of condensation inside the case, which can lead to a short circuit. Just bring the phone into a heated room, the battery will gradually thaw and after a few minutes the smartphone will turn on.
If you need a working device immediately, but there is no way to go into the room, then you can try to warm up the power sensor by blowing warm air from your mouth into the charging connector. However, this method is not safe, as there is a possibility of condensation. Therefore, this method is only at your own risk.
