Who can recommend a mobile phone battery that does not falsely label the battery level?

If you buy a big domestic brand, you can; Such as scuds, endurance, etc.; If you can identify the quality of the product, you can also buy the brand products of small and medium-sized manufacturers; The bulging of the mobile phone battery is generally due to air leakage, and it is usually the beginning of the inability to continue to use; The battery of the mobile phone is bulging, which has no effect on the life of the mobile phone; However, some batteries are prone to bursting after the bulging; In the small space of the mobile phone, it is easy to damage the mobile phone; Therefore, do not use the battery after the drumming; Generally, the life of a mobile phone battery is determined by the number of times it is charged and discharged; Generally, the number of recharged batteries for repair and refurbishment is about 50 times, so when you buy, you will swear to tell you that the warranty is three months or half a year; Once the warranty period is over, it will definitely not be long; The number of charging and discharging of batteries produced by ordinary manufacturers is about 100-180 times; The term of use is about one to two years; The battery charged and discharged by a good manufacturer is about 200-300 times; The term of use is about two to three years; The imported and original batteries can be charged and discharged more than 500 times, and the service life is longer; The most taboo of general batteries is overcharge and overdischarge; As long as these two principles are followed, the maximum use and maximum service life of the battery can be used.

All are lithium batteries;

"Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the anode material and uses a non-aqueous electrolyte solution. In 1912, lithium metal batteries were first developed by Gilbert NLewis proposed and studied.

In the 70s of the 20th century, m s.Whittingham proposed and began research on lithium-ion batteries.

Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been applied for a long time. With the development of science and technology, lithium batteries have now become the mainstream.

Lithium batteries can be broadly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain lithium in a metallic state and are rechargeable.

The fifth-generation product of rechargeable batteries, lithium metal batteries, was born in 1996, and its safety, specific capacity, self-discharge rate and performance** ratio are better than those of lithium-ion batteries. Due to its own high technical requirements, only a few companies in a few countries are now producing such lithium metal batteries.

At present, there are two main types of batteries on the market: nickel-metal hydride (Ni-MH) and lithium-ion (Li-ion).

There are two types of lithium-ion batteries that have been mass-produced: liquid lithium-ion batteries (LIB) and polymer lithium-ion batteries (LIP). So in many cases, the battery marked with li-ion must be a lithium-ion battery. But it doesn't have to be a liquid lithium-ion battery, it could also be a polymer lithium-ion battery.

Lithium-ion batteries are an improved version of lithium batteries. Lithium batteries have been around for a long time, but lithium is a highly active (remember where it is in the periodic table?). Later, there was an improved lithium-ion battery, which added ingredients that can inhibit the activity of lithium elements (such as cobalt, manganese, etc.) so that lithium battery is truly safe, efficient and convenient, and the old lithium battery has basically been eliminated.

As for how to distinguish them, they can be identified from the identification of the battery, lithium batteries are LI, and lithium-ion batteries are LI-ion. Nowadays, the so-called "lithium batteries" used in laptops and mobile phones are actually lithium-ion batteries.

The basic structure of a modern battery consists of three elements: a positive electrode, a negative electrode, and an electrolyte. As a type of battery, lithium-ion batteries also have these three elements. Typical lithium-ion technologies use liquid or inorganic colloidal electrolytes and therefore require a rugged housing to contain the flammable active ingredient, which increases the weight and cost of the battery, as well as limits the flexibility of size and styling.

Generally speaking, the minimum thickness of liquid lithium-ion rechargeable batteries is 6mm, and it is difficult to reduce it.

The so-called polymer lithium-ion battery is a battery system in which at least one or more of the three main structures use polymer materials as its main battery system. The new generation of polymer lithium-ion batteries has a high degree of polymerization, so the shape can be thinned (the thinnest millimeter), arbitrary area and arbitrary shape, which greatly improves the flexibility of battery modeling design, so that it can be made into batteries of any shape and capacity according to product requirements. At the same time, the unit energy of polymer lithium-ion batteries is 50% higher than that of current general lithium-ion batteries, and its capacity, charge-discharge characteristics, safety, operating temperature range, cycle life and environmental performance are greatly improved compared with lithium-ion batteries.

If your phone is a smartphone.

That's the ion battery, and it's all this now.

When the power-saving management function is enabled, there are also four power-saving management modes: intelligent mode, ultra-long standby, extreme mode, and initial mode.

In smart mode, the battery manager retains normal calls, texts, and network functions, and dynamically adjusts the screen brightness according to the specific situation to obtain the most reasonable power arrangement.

When it is converted to ultra-long standby mode, it retains normal calls and text messages, and turns off the WiFi network. In Extreme mode, all power-hungry functions are turned off, leaving only alarms and daily functions.

Hello. Today's mobile phone batteries are basically lithium batteries.

The characteristic of lithium batteries is memory charging.

The best charging time is between 15%-25% of the battery remaining.

It won't take up too much of your memory.

The CPU running frequency can be intelligently adjusted.

Intelligently adjust system parameters and turn off programs that consume a lot of power.

It is charged in three stages.

Greatly improve the service life and standby time of mobile TV.

Nowadays, mobile phones are all lithium batteries, so you don't have to separate, oh.

Today's mobile phone batteries are lithium batteries and nickel-cadmium batteries, nickel-metal hydride batteries.

How to maintain longer battery life

If you use your phone regularly, keep the battery at 20%-70%.

This can make the charge voltage normal and reasonable.

If you don't use your phone often, keep the battery at 50%.

It is best to charge the battery to 50 if it is not used for a long time, and recharge the battery to 50 every six months at most.

Do you know these misconceptions?

Playing while charging is good for the battery, but it doesn't hurt

Because the charging current will be directly supplied to the normal operation of the stimulated type, the excess power will be charged to the battery, so charging and using it at the same time will not let the battery discharge while charging, because the battery will not be discharged at this time.

There is no benefit to being full, but it is a disadvantage

No matter how much power is left in the battery, it can be charged, because lithium batteries have no memory, on the contrary, if the power is completely used to 0 and then recharged, it will cause some damage to the battery because of the charge voltage.

It is better to use it with a plugged power supply than to use it without a power supply

The loss of the battery will be less than the loss of the battery when the battery is used directly when the power supply is plugged in, but if it is connected to the charger for a long time, it is recommended to fully charge and discharge the battery at least once a month to ensure the battery is active.

A reasonable explanation for some malfunctions

In winter, the device is less than 100 when it is close to 100

The normal phenomenon is that there is a deviation between the calculation of the power management system and the actual capacity of the battery, and the power can be completely used up after the charging cover is fully charged to carry out a calibration6In winter, it is normal for mobile phones and computers to not be charged, because if the power management system detects that the battery temperature is below zero, it will turn off the charging inlet, and as long as the temperature returns above freezing, it can be charged normally.

If you want to purchase and experience Samsung product accessories (batteries, earphones, smart holsters, chargers, memory cards, etc.), you can purchase them through the following channels:

1.Samsung Online**: Go to Samsung Online ** - Accessories to buy.

3.Samsung stores around the country.

4.Samsung after-sales service center.

At present, the mobile phone on the market uses a lithium battery, and the battery has been activated when it leaves the factory, and the lithium battery has no memory, so it can be charged at any time. When the battery is fully charged, it can be powered off (after the first three full charges, it can be charged for another 1-2 hours).

Here are a few tips for charging your phone:

1.Do not over-discharge. When the device prompts that the battery is low, it should be charged; Charging is not until the device is automatically turned off, and the battery has been over-discharged. This can affect battery life. So when the phone prompts that the battery is low, it can be charged.

2.Do not overcharge. When the charger gives a full charge, it should be unplugged.

Now the charger generally has a full self-stop design, it doesn't hurt to take off the battery from the charger for a short time, but leave the battery on the charger for a long time, and the grid voltage rises in the middle of the night, and the charger that has stopped charging will continue to charge after the voltage rises, causing the battery to overcharge. This can affect battery life.

3.If the battery is not used for a long time, it should be charged to 60%, stored separately in a cool and dry place, and recharged every other month.

4.It is recommended not to use the mobile phone when charging, and it is on standby for charging.

1.Samsung phones come standard with a lithium-ion battery. Because the lithium battery has no memory function, it can be charged at any time, can be charged shallowly, and can be used when fully charged.

Note: Do not charge after the power is completely exhausted, it will affect the battery life.

2.Do not use your phone during the charging process, it is best to turn it off for charging.

Here are a few tips for using your phone's battery:

1.Do not over-discharge. When the device prompts that the battery is low, it should be charged; Charging is not until the device is automatically turned off, and the battery has been over-discharged. This can affect battery life.

2.Do not overcharge. When the charger gives a full charge, it should be unplugged.

The current charger generally has a full self-stop design, and it doesn't hurt to remove the battery from the charger for a short time, but if the charger is connected for a long time, the grid voltage rises in the middle of the night, and the charger that has stopped charging will continue to charge after the voltage rises, causing the battery to overcharge. This can affect battery life.

3.If the battery is not used for a long time, it should be charged to 60%, stored in a cool and dry place separately (not a single model), and replenished every other month.

At present, mobile phones are designed with lithium batteries, which have no memory function and can be charged at any time. And it has a long service life.
