Just charge up and go out

This sentence must be very familiar to everyone.

Before we go out, we usually check the battery level of our phones first,Some people feel insecure when their phones are not fully charged and they go out.

But sometimes, even though the phone still has half of its battery, it still wants to charge.

Some people say that phones must be fully charged before they can be charged,Some people also say that you need to charge halfway through the use.

So which of these two statements is correct?

In the 1970s, Motorola engineer Martin Cooper borrowed communication devices from the science fiction film "Star Trek",Invented the first mobile phone, also known as the 'Big Brother'.

At this time, the phone was bulky and weighed over 1 kilogram, as it used nickel cadmium batteries that accounted for half of its volume. However, nickel cadmium batteries had the advantage of being cheap, easy to obtain raw materials, and could be reused up to 500 times,It can provide high current and fully meet the call needs at that time.

Because the main function of mobile phones at that time was to make calls, the requirements for batteries were simple and direct, as long as they could support calls.

However, nickel cadmium batteries have a "memory effect" issue. If users start using them without fully charging, the battery's capacity will always remain at the initial usage level and cannot be fully utilized.

So at that time, the older generation would advise to fully charge the new phone and pre charge the battery like a "meat dish", in order to unlock the full capacity of the battery,If this' preheating 'process is not done properly, it will result in the battery capacity being limited to a lower level for life.

In the 1990s, with the increasing functionality of mobile phones, users' demands for battery life and weight became increasingly high, and nickel cadmium batteries became increasingly scarce.

The second generation mobile phones, on the other hand, used nickel hydrogen batteries to replace bulky nickel cadmium batteries. This type of battery has many advantages over nickel cadmium batteries, such as smaller size, lighter weight, and no obvious memory effect,The battery life can be increased by 30-60 minutes compared to nickel cadmium batteries, and the weight is also reduced by about 15%.

However, nickel hydrogen batteries also have problems. If overcharged, it can cause the battery to heat and expand, shortening its service life. If not properly charged, nickel hydrogen batteries can also have a certain memory effect. Therefore, many brands at that time would write in their manuals not to overcharge, and once the battery is fully charged, they should promptly unplug the power supply.

The real breakthrough in battery technology was the lithium-ion battery that emerged in the late 1990s, which used layered cobalt oxide lithium as the positive electrode and carbon as the negative electrode,The lithium ions between the two poles can freely embed and detach during charging and discharging, thus achieving the storage of electrical energy.

This type of battery has revolutionary progress compared to the previous two generations. It is lightweight, has no memory effect, and can be charged and discharged at any time, completely free from the troublesome limitations of the past. It is very convenient. More importantly, it has no memory effect and can be charged and used at any time without affecting the battery capacity, which also provides great convenience for users.

Lithium batteries charge quickly and have a long battery life, and can support phone usage for hours or even days on a single charge, which has completely changed people's usage habits.

However, lithium batteries also have safety hazards and may cause explosion accidents under high temperature conditions. Therefore, it is important to avoid charging in high temperature environments, as they are considered the "21st century battery",The significant increase in energy density has made it the preferred choice for smartphones today.

Initially, users only focused on whether the battery could support calls. Later, they pursued longer battery life, and now they place greater emphasis on charging safety. This also reflects the increasing demand for mobile phone functionality,From being able to make calls to having more powerful and diverse applications.

People are gradually questioning how to charge their phones to make their battery life longer?

Is it enough to flush half of the phone?

Have you ever wondered if your phone can be charged when it's half full? How much battery should the phone be charged to? Can I play with my phone while charging?

These issues are actually related to when we choose to charge our phones.

Previously used nickel cadmium batteries did indeed have a battery memory effect, and if they were frequently recharged after depletion, it would shorten the battery's lifespan.

But now the lithium-ion batteries widely used in mobile phones,There is no memory effect issue.

As long as the battery is not completely depleted, charging at any time will not cause harm to the battery. However, we should still use the battery reasonably to avoid frequent charging and discharging cycles.

The working principle of lithium-ion batteries is that during the charging process, lithium ions flow from the positive electrode to the negative electrode,During the discharge process, lithium ions flow from the negative electrode to the positive electrode.

If there are long-term repeated charging and discharging cycles, it will lead to the formation of a solid electrolyte interface (SEI) on the negative electrode surface of the battery. If this interface is too thick, it will reduce the storage capacity and endurance of the battery.

So don't often let your phone run out of battery before charging. Lithium batteries can undergo hundreds of charging cycles,But if the battery runs out of charge every time, the number of cycles will quickly reach the upper limit and the battery performance will decrease.

A reasonable approach is to charge when the battery level drops to around 30%, which can maximize the cycle life.

Of course, you can unplug the charging cable after charging to 80%.

Nowadays, most mobile phones have overcharging protection function, which can avoid overcharging. However, long-term charging can still accelerate battery aging by leaving the battery in a high voltage state.

So if you charge it to 80%, you can unplug it and charge it to 100% later.

More importantly, we should avoid frequent use of mobile phones during charging.

Because playing with a mobile phone can cause the battery to heat up, and heat is the biggest killer of shortening battery life,So when charging, it is important to minimize other uses of the phone and avoid placing it in a hot area for charging.

So try not to charge in direct sunlight,Do not play games or watch videos while charging, as this can cause the phone to heat up.

Of course, choosing to use an original charger is also important.

Some counterfeit chargers have unstable output voltage and current, which can cause damage to the battery,Causes the battery to heat up and expand, resulting in a decrease in battery life.

When the phone has half of its battery remaining, it does not necessarily need to be charged immediately,However, frequent deep discharge should not be allowed. The battery should be used reasonably, and the charging frequency should be controlled to avoid overheating.

Developing good mobile phone usage habits can prolong the battery life.

Explosion-proof tips for mobile phones

Nowadays, smartphones have become essential electronic devices in most people's lives.

There are many reasons for the explosion of mobile phones. In addition to high ambient temperature and improper operation, some brands of mobile phones can also cause explosions due to design and manufacturing defects. Therefore, when purchasing a mobile phone, it is still necessary to choose a large brand with guaranteed quality.

Some small brand phones often cut corners on materials and craftsmanship in order to reduce costs,Once problems arise, they can easily lead to safety accidents.

However, it should be noted that replacing the battery must be done at a reputable repair point,Do not disassemble or disassemble by yourself, otherwise incorrect operation may cause a short circuit.

Also, in daily life, it is important to keep your phone clean, prevent a large accumulation of dust, and prevent liquid from entering the battery area.

Dust can block the phone's heat dissipation holes, affecting the heat dissipation effect. Liquid entering the battery area can easily cause short circuits,So it is important to clean the dust on the surface of the phone in a timely manner, and do not let the phone come into contact with liquids such as water.

Many children nowadays start using electronic devices such as mobile phones at a very young age.

Parents should pay attention to cultivating their children's awareness of safe use and inform them of some explosion-proof knowledge,Avoid charging your phone in hot and high-temperature environments, and handle it promptly when encountering water.

Also, it is advisable not to allow children under the age of 5 to use smartphones for extended periods of time, in order to avoid damage to their vision caused by radiation and prolonged close-up viewing of the screen.
