When the weather gets cold, why does your phone suddenly run out of battery or even shut down automatically?

Winter always brings infinite beauty, but also some small troubles...

I believe some people may encounter this situation, such as:

While shooting snow scenes outdoors, the phone was "frozen" and malfunctioned frequently, and the battery was quickly dropping; it automatically shut down even though it still had power, and when I plugged in the charger, I saw that the power was still at 50% or 60%; some people's phones suddenly shut down when using them outdoors, but they resumed normal use after being put in their pockets for a while.

When the temperature drops low enough, you will find all sorts of problems with your phone: slow response! Crazy battery loss! Crazy freeze! Simply shut down! At this point you may think there is a problem with the quality of the phone, but in fact you don't know that it is the low temperature that is to blame.

When your phone has this problem, it is not because it is broken, but because it has caught a cold. Everyone can get sick, so why not your phone? When the temperature drops to a certain level, your phone will freeze! It will become unresponsive! It will lose power like crazy! Finally, it will just shut down!

Why does the battery of mobile phone run out quickly in winter?

The smartphones we usually use are generally powered by lithium batteries. Their working principle is that the internal electrolytes form a potential difference through chemical reactions, thereby generating current. In low temperature environments, the chemical reaction rate of lithium batteries slows down, so the discharge current becomes smaller and the power decreases. When the phone turns on the battery low temperature protection, it may automatically shut down.

The main reason why mobile phones become like princesses in winter is the low temperature. Mobile phone screens are also prone to malfunction in low temperature conditions and are particularly prone to breaking by themselves.

The official website of iPhone has clear instructions that the normal operating temperature is 0~35℃; the optimal operating temperature is 22℃; the extreme temperature is -20~45℃. Of course, we know that iPhone will not work properly when it is close to 0℃!

So, what about Android phones? Actually, it is similar. Most of them work normally at -10~50℃. For general Android phones, once the temperature drops to -10℃, the screen of the phone starts to dim and enters a low-battery state; at -20℃, it is almost impossible to turn on the phone, and at -30℃, the screen and battery are unusable, not to mention lower temperatures.

Tips for saving battery on your phone?

1. Lower the brightness of your phone appropriately

The default setting of many mobile phones is to automatically adjust the screen brightness. In this way, when the light is strong, the mobile phone will generally work at the highest brightness, and the power consumption is very fast at this time. Therefore, if you want to save power, first remember to lower the screen brightness, which will save a lot of power.

2. Close unnecessary background programs

Many times, the battery of a mobile phone is lost inadvertently. For example, some mobile phone applications have been running in the background after opening. If you close the opened applications in time, the automatic operation of mobile phone applications will continue to increase power consumption.

How to maintain your mobile phone in cold season?

1. Do not turn on the device immediately after it automatically shuts down and you return to the room

If your phone shuts down automatically when it is outdoors at low temperatures, do not turn it on immediately after returning indoors as this may damage the phone's components. Wait until the phone's temperature returns to normal before turning it on again.

2. Try to use your phone less outdoors on snowy days

Friends should try to avoid using their mobile phones outdoors in rainy and snowy weather, and keep the mobile phone charging interface and other sockets dry. First, to prevent low temperatures from affecting battery performance, and second, to prevent water vapor from invading the inside of the mobile phone and causing circuit board failure.

3. Keep your phone warm in your pocket or bag

Try to avoid using your phone for a long time in a low-temperature environment. When you go out, keep your phone close to your body, or put it in a warm place such as a pocket or bag.

4. Use headphones to answer calls outdoors

In low temperature environments, you can use Bluetooth headsets or wired headsets when you need to make or receive calls, so that you don't have to hold your phone in your hands to "freeze"!

5. Take off your phone case when charging

When charging a mobile phone in a protective case, excessive heat may be generated, which will affect the battery capacity. It is recommended that you take off the phone case before charging.
