In winter, mobile phones consume power fast and react slowly? Try these tricks!

The weather is getting colder, many people report that the phone power is falling faster and faster, and even when the outdoor power reaches about 30% or 40%, it will automatically shut down, why is this?

In fact, this is due to the temperature becoming lower, and the temperature drop leads to a temporary decrease in battery performance. Why is battery performance degraded? What is the normal use temperature of the phone? What are some power-saving tips for low temperature weather mobile phones?

Draw the point

01

Why is battery performance degraded?

Mobile phone batteries generally use lithium batteries and nickel-metal hydride batteries, and mobile phones consume electricity quickly in winter, as far as lithium batteries are concerned, they cannot withstand low temperatures, the normal working temperature of mobile phones is 0 ~ 35 ° C, the best use temperature is 22 ° C, and the limit temperature is -20 ~ 45 ° C.

Therefore, when the ambient temperature of the mobile phone is close to about 0 ° C, it will affect its work efficiency.

02

What is the normal use temperature of the phone?

The best use temperature: 16 °C - 22 °C, normal use temperature: 0 °C - 35 °C, the temperature range that can be stored: -20 °C - 45 °C, the temperature is lower than 0 °C, the mobile phone may enter the automatic freezing state.

If the temperature exceeds 35 ° C, the phone may be alarmed because the battery is overheating and automatically shut down at the same time.

Using the ambient temperature is too high or too low, it will affect the running speed of the mobile phone, and may even lead to automatic shutdown. In addition, in the low temperature environment, mobile phones will also have difficulty in charging.

03

Why does my phone lose power in cold weather?

Most mobile phones use lithium-ion batteries (that is, what we usually call lithium batteries), which is composed of a positive electrode, a negative electrode, and an electrolyte between the positive and negative electrodes, and the negative electrode precipitates the lithium ions through chemical reactions, and the lithium ions generate a current during the movement to the positive electrode.

In a low temperature environment, the chemical reaction speed of lithium batteries slows down, so the discharge current becomes smaller and the power drops.

What are some power-saving tips for low temperature weather mobile phones?

1. Reduce the screen brightness

The biggest killer of mobile phone batteries is not the CPU, not the phone, but the larger and larger mobile phone screen, the default setting of many mobile phones is to automatically adjust the screen brightness, so that when the light is strong, the mobile phone will generally work at the highest brightness, and the power consumption at this time can almost be measured by two minutes off 1%.

Therefore, if you want to save power, first remember to reduce the brightness of the screen, which will save a lot of power, especially for large-screen mobile phones above 4 inches. However, many mobile phones now also have the function of low-power mode, so turning it on when the weather is cold, or when the battery is low, which will greatly reduce the battery consumption.

2. Turn off push notifications

Many people often use "notifications" to remind you to use it, but if you don't want to use power, let it rest as much as possible. First, for newly installed software, select "Do not allow push notifications"; second, for installed software, in the Settings - Notification Center, selectively turn off or all off.

3. Close the backgrounder

Many times the phone power is inadvertently lost, such as the mobile phone has a background program in the work, timely close the open program, do not let these programs have been running automatically in the background, otherwise the internal core of the mobile phone has been in a high-speed computing state, increasing power consumption.

4. Reduce sound and vibration

The power consumption of the mobile phone is also reflected in the sound and vibration, so you can choose to reduce or turn off the ringtone of the mobile phone, while trying to avoid ringing and vibration turning on at the same time.

Also, reduce some unnecessary sound options, such as turning off key tones and lock tones (it is recommended to keep silent mode vibrations, otherwise you may miss important calls or notifications).
