How can the lithium battery of the new mobile phone not be charged into the emergency

It is necessary to determine the reason why the battery cannot be charged

1.The phone battery cannot be charged, and it is possible that the battery has entered a dormant state. This is mostly caused by the user running out of power and the phone automatically shuts down.

The solution to this situation is to remove the battery, wait 5 minutes, and then reinstall the battery. Use a data cable to connect your Mi phone to the computer, and after 30 minutes, turn it back on.

2.In the case of sudden mobile phone battery not charging, you also need to check whether you are using a regular original charger. If you are using a different charger, you need to check if there is a problem with the charger or if the charger port is damaged.

Switching to a new charger can solve this situation.

3.If there is a situation where the mobile phone can be connected to the charger to charge, but it is always not charged, I need to check whether there is a problem with the mobile phone system. Sometimes, you install battery management software that protects the battery on your phone, and when there is a problem with these software, the battery will not be fully charged.

You can use a universal charger to charge the battery of your mobile phone and check whether the battery is damaged. If the battery can be fully charged with universal charging, then you should repair the phone system or flash it.

4.In addition to the above situations, the loose charging interface of the mobile phone and the short circuit of the internal charging circuit of the mobile phone will also cause the mobile phone battery to not be charged. In this case, you need to send the mobile phone to a professional after-sales repair network for maintenance.

The new mobile phone should be charged directly, and the battery should be charged with a universal charge. There are several possibilities for not charging: the battery and the phone are in poor contact; This battery is refurbished and has a long lifespan; There is a problem with the phone; There is a problem with the direct charger; If there is a problem with the battery, take it and replace it.

I've seen a lot of your problems I am in the mobile phone industry: I know your problems very well, so let me analyze them for you

The so-called high-capacity battery, its life is fully higher than the life of the ordinary battery, it can't be said that it won't be rotten, and it will be the same as the ordinary battery, it will cause automatic shutdown, and so on, the general ordinary battery is between 20 yuan and 40 yuan, and the high-capacity battery is 80 yuan to 100 yuan

So, what about it: your current problem 90 parts of white is caused by the battery Buy a battery Buy a battery and everything will be fine I guarantee my life You can rest assured that you can buy a high-capacity battery because it is still more cost-effective Okay Don't talk about it I repaired the machine 88

The new mobile phone will be replaced in 7 days, go and change it for 1, and if you just buy it, there will be a problem, and you will not change it.

The gold and profit I bought are all for 30 days, generally for 7 days, if you can't replace it, go to the place where you buy a mobile phone, try universal charging, if you can use it, buy it, don't use it, don't spend money to buy a charger ps: Magnum Chong is generally about 15 yuan, don't be deceived.

The "2007 Battery Industry Search Index" was launched on January 23, 2008 with the voice and support of colleagues in the battery industry. This data is completely free to share, which is undoubtedly a great gift for users and enterprises in the battery industry at the beginning of 2008.

With the segmentation of the Internet industry and the development of enterprise focus, more and more users need more detailed, more specific, more purposeful, in this form, most users will directly search for what they want on the **, and then, the information in the search results becomes particularly important, because this information is the user through their wishes, input keywords, and the results of matching.

After more than a year of data statistics, analysis, summary, writing, and many revisions and reviews, the final draft was finally determined on January 23, 2008 and shared with you.

The 2007 Battery Industry Search Index involves nearly 3,000 words and product terms related to the battery industry, involving battery materials and accessories, finished batteries, battery production and testing equipment and other classifications.

This data is the first time in the battery industry to launch an authoritative, extensive, refined, practical comprehensive data, its appearance, breaking the battery industry so far has no reference to the embarrassing situation of user attention data.

The disclosure and sharing of this data fully demonstrates another layer of service of China's battery network: using data to serve the industry and proving its strength with service.

You can charge it with a multi-function charger.

What should I do if the lithium battery can't be charged.

1.In the use of lithium batteries, it should be noted that the battery will go into a dormant state after a period of time.

2.Self-discharge will deplete the battery, and the capacity will be lower than normal, causing the battery to be too low to charge.

3.But the lithium battery is easy to activate, as long as it goes through 3-5 normal charge-discharge cycles, the battery can be activated and the normal capacity can be restored.

4.Due to the characteristics of the lithium battery itself, it is determined that the lithium battery has almost no memory effect, so the new lithium battery in the user's mobile phone does not require special methods and equipment during the activation process.

5.Not only in theory, but in my own practice, it is best to use the standard method of charging this "natural activation" from the very beginning.

What is the reason why the lithium battery cannot be charged?

There are many kinds of lithium batteries, there are batteries composed of round cells like 18650, and lithium batteries composed of polymers, if they are divided into two categories, then they are lithium metal batteries and lithium-ion batteries, and the charging methods are basically constant current charging, constant voltage charging, pulse charging, etc., different charging methods are used at different stages, if the charging cannot be charged, there are only several situations:

1. The lithium battery is in an over-discharge state.

That is to say, the lithium battery is discharged very low, in a deep discharge state, and the power is basically used up, so that it is as low as the cut-off voltage of the lithium battery, and the activation method can be taken at this time, but this is not necessarily effective;

2. There is a problem with the charger or charging line.

First of all, you should check whether there is a problem with the charger, the method is very simple, directly measure the output voltage or connect the load of the corresponding voltage to observe, as for the line if there is a problem, then it will take some effort, after all, it involves circuit hardware and other issues, when necessary, directly disassemble and analyze;

3. The lithium battery has been used for a long time and the battery fails.

The possibility of this happening is relatively small, but it cannot be ruled out that your own battery should be familiar with it, and you should replace the battery after how long it has been used;

4. There is a problem with the battery charging IC or BMS system.

Problems occur in the battery management system due to cell imbalance, etc., resulting in misjudgment of the management IC and failure to detect voltage or current.

Generally, the reason for the failure of lithium battery charging is that the battery life has reached or it is damaged during use. For example, the mobile phone battery is not always usable, it also has a service life or the number of times or duration of charging, and when it reaches a certain value, it will fail to charge and need to be replaced.

First check whether the connection is correct, whether the wire is reliably connected, if these are all right, usually the battery is broken, of course, the charger is broken.

The lithium battery cannot be charged, the battery is full, the charger is faulty, the charging line is faulty, the lithium battery line is faulty, and the lithium battery is damaged.

2.The internal charging circuit of the mobile phone is faulty and cannot be charged normally.

3.If the battery can be charged, then it means that there is a problem with the data cable or mobile phone jack. If not, then it's a problem with the battery.

If it is a problem with the battery, there is a small way, wrap the battery in newspaper and put it in the refrigerator to freeze for three days, then take it out, try to put it in a ventilated place to dry for a while, and then the battery will be fine.

4.If there is a problem with the mobile phone socket, try to wipe the dust inside the interface with a brush or a small brush, or it may be caused by excessive dust accumulation on the interface. If wiping still doesn't work, it is recommended to change a socket or a data cable.

It is possible that the problem is caused by poor contact with the power supply.

5.Check whether there are foreign objects in the mobile phone charging interface, such as liquid ingress, debris that causes poor contact between the mobile phone charging interface and the charger, if this situation is recommended to be repaired as soon as possible. Back up your phone's data (book, SMS, etc.) and factory reset your phone (go to phone settings - reset - factory reset).

6.Try not to make calls while your phone is charging**. A good habit is to turn off your phone while it is charging, so that you can ensure a good quality charge.

In the process of using the mobile phone, try to charge it healthily every time it is charged, that is, when the power is less than 20%, and never wait until the power is exhausted to recharge, so as not to affect the service life of the mobile phone battery.

If the phone cannot be charged, Samsung mobile phones are generally recommended to perform the following steps to troubleshoot and deal with them:

1.Use the original charger to connect to the home power source for charging.

2.Replace the power outlet, try or change a data cable to connect to the charger for charging.

3.If the phone can be turned on normally, it is recommended to back up the data in the phone (such as contacts, multiple files, etc.) and restore the phone to factory settings.

If the problem persists according to the above methods, please bring the purchase invoice, warranty card and machine to the nearest service center for inspection.

Lithium batteries have protective devices. If it's fully charged, it can't be charged. Aging lithium batteries can't be charged.

The battery is broken, or the battery is disconnected and not installed properly. This is equivalent to not having a battery installed. Check to reinstall the battery or replace the battery.

The lithium battery can't be charged, and the original activation method is so simple, just use a mobile phone charger to get it.

Now it's all all-in-one. to the aftermarket replacement battery.

We know that lithium batteries do not have a "memory effect" like nickel-chromium batteries, and now we often see basically lithium batteries, 18650 also belongs to a kind of lithium batteries, after not using the battery for a long time, you will find that the battery cannot be charged, which is caused by over-discharge, that is to say, the voltage of the battery has been lower than the cut-off voltage of battery discharge, and it is generally around for the general lithium battery.

What to do with batteries that have not been used for a long time or have reached a very low discharge voltage, and can they still be activated? When it comes to activation, many lithium batteries will not exist as a single unit, but in the form of a battery pack, then there will generally be a charging management board, the main part is the charging management IC, this IC overcharge, overdischarge, overcurrent, short circuit and other protection functions, for the discharge of lithium batteries will set a minimum limit, placing the battery over-discharge leads to irreversible reaction, that is to say, our battery can not be charged for a long time. Then sometimes you can use the "activation" method to give it a try.

Lithium battery charging generally adopts the method of "constant current --- constant voltage", that is to say, it is charged with standard current for a period of time at the beginning, and when the battery voltage reaches the charging cut-off voltage, constant voltage charging is used. Therefore, it can be charged with DC power for a period of time, and then switch to the original charger to charge when the cut-off voltage is reached, although this method is sometimes feasible, but it is not all possible, after all, the battery overdischarge has affected the performance of the battery, but there are also batteries that have been placed for several years can also be activated.

So how to take care of lithium batteries?

Due to the self-discharge phenomenon of lithium batteries, if the battery is not in use, if it wants to be well preserved for a long time, the battery voltage cannot be lower than its cut-off voltage, preferably around to;

It is recommended that the lithium battery be charged once every six months, so that the battery is kept above the cut-off voltage;

The temperature and humidity of the battery storage environment should be appropriate, and it should be operated in accordance with the specifications;

It is best not to charge new and old batteries, batteries of different brands, capacities, and types together or randomly mix them together to charge a battery pack.

Hello: The reasons why the battery cannot be charged are:

Problems with the battery itself, such as damage caused by over-discharge;

The charging cable is in poor contact or may be disconnected;

It is not ruled out that the charger is damaged and cannot be charged.
