New battery charged? Why is the new battery undercharged?

The new battery needs to be activated, because the battery has not been used for a long time, the plate material loses its activity, and it can be charged and discharged five or six times before the performance of the battery can be brought into play.

Maybe you have bought an inferior product, and there is a problem with the battery. If you contact the warranty as soon as possible within the warranty period.

1. Background program.

During the charging process of the mobile phone, there are too many programs running in the background, and the charging speed is slow due to large power consumption.

Solution: When the mobile phone is charging, avoid using the mobile phone, and try to close the programs running in the background to reduce the power consumption during charging.

2. Charging equipment.

The insufficient current of the mobile phone charger will cause the resistance to increase, which will reduce the actual power charged into the battery, and the mobile phone will not be fully charged for a long time. In addition, a damaged phone charger may also cause the charger to run out of charge.

Solution: Use the original charging equipment of the mobile phone for charging, or try to replace the charging equipment with the same specifications and parameters for charging observation to eliminate the fault of the charging equipment.

3. Poor contact.

Observe whether the mobile phone charging tail plug is dirty and deformed.

Solution: If the tail plug is dirty, you can use a cotton swab or soft cloth to clean it, if the tail plug is deformed, it is recommended to back up important information and send the phone to the after-sales service for testing and processing;

4. The power display is abnormal.

If the battery level does not change when the phone is charging, or the battery level does not change after reaching a certain value, the battery level display of the mobile phone may be abnormal.

Solution: 1. Turn off the phone and restart it to observe whether it returns to normal;

2. Try to charge in the shutdown state to see if it can be fully charged;

3. If the shutdown and reboot or shutdown charging are still abnormal, it is recommended to back up important data and restore the factory settings.

It is recommended to replace the charger and purchase branded products. If this situation suddenly occurs in the old car and old charger, one reason is the charger problem, use it twice more to see, it may be an occasional situation, if it has been like this, it is recommended to replace the charger.

Related Notes:

Any battery has a self-discharging characteristic, so when a new rechargeable battery arrives in your hand, it may have been self-discharging for a while. This means that the chemical raw materials inside the rechargeable battery have not been used for a period of time, and there is a state of "passivation", which cannot fully exert the chemical reaction and provide sufficient voltage.

In this case, when using the rechargeable battery for the first time, be sure to fully charge the rechargeable battery and allow the voltage to return to its original level. In fact, if your rechargeable battery is left unused for a long time, this "passivation" phenomenon will also occur, and it will be more serious. It is best to charge and discharge the rechargeable battery 3 times, which will help the rechargeable battery to be activated.

This allows the chemicals inside the rechargeable battery to fully exert its desired effect (nickel-cadmium battery).

Sometimes, when a newly purchased rechargeable battery is put into the charger, the charger will stop charging before it is fully charged. When this happens, you just need to remove the rechargeable battery from the charger and put it in the charger to continue charging. This is normal for new rechargeable batteries, not for you to buy a bad rechargeable battery (NiMH, Li-ion).

Generally speaking, the charging time should not be too long, a maximum of 12 hours is enough, if it is overcharged, it will cause damage to the rechargeable battery.

The main reason for the undercharge is that the overcharge protection threshold of the new battery comes with a low overcharge protection threshold. In this way, when the protection board has reached the overcharge protection threshold and turned off the input, the system still detects the power according to the original voltage, and the corresponding low power is detected.

For example, the original volt corresponds to 100%, corresponding to 80%, and the new battery's protective plate is only charged to volt, then the corresponding is 80%. (Examples).

Hello, the oxidation and rust of the mobile phone battery contacts leads to an increase in impedance, the battery is installed inside the mobile phone for a long time and is in contact with the human body, due to the humidity (such as sweating, water vapor) is very large, resulting in the battery contacts are prone to oxidation and rust, and a long time and the mobile phone motherboard contacts produce a large current limiting resistance, which will also make the charging current insufficient and difficult to fill.

Questions. Is it related to the punch interface?

Shi Fu cleaned up the interface and said that there was a problem, and Yundian has been fine.

It is a contact point in the battery.

Questions. With two days, it is not as good as the old one.

The maintenance technology is not up to par.

If there is no old ***, then there is a quality problem with the battery you bought.

Questions. Huawei's official electricity.

Solution: Remove the mobile phone battery, find the battery contacts, use a cotton swab or pencil nib to put on a clean toilet paper (if possible, you can use 0 sandpaper to cut it into small thin strips), clean each electric shock, until the contact reveals the true color of brass, if there are too many oxides that are difficult to remove, you can use a pin or utility knife tip to remove them one by one, but be sure to pay attention to the need to clear them one by one, and you can not touch two contacts at the same time, otherwise a short circuit may occur**; Finally restore the battery and try to recharge.

Hello: 1, the battery is not powerful, with the battery's [Date of manufactureThe relationship is very large, the date of the battery factoryThe closer the betterAccording to experience, it should not be more than half a year.

2. If the battery takes time in the production, warehousing and transportation links, as well as the storage time of the merchant, we should also pay attention to the batteryExpiration dateetc. Also, avoid sub-quality, inexpensive non-batteries.

You try to change a charger, some of the poor contact can be fully charged with a charger, you will generally be full for a day, if you can't flush and then change a battery.

It must be that the electromagnetic is not the original factory, not the original electromagnetic and yours are not matched.

Are you charging your phone? A battery that is not original may not be suitable.

This is because the phone's battery has a virtual charge.

Virtual power phenomenon: [Interpretation]: It means that the battery has been in a semi-active state and a semi-charged state, and the displayed power of the battery is very high, but the actual power is relatively low, not the real power of the battery. The battery is fully charged after a short period of time, but it runs out quickly.

Apple mobile phone battery: It is an energy storage tool that provides power for the mobile phone, which is composed of three parts: the cell, the protection circuit and the shell.

How to charge it correctly]:

1. The charger must be original. In the same way as the charger, the charging cable should choose the original cable, especially if there are several cables that look the same on the socket, you must mark it in advance to avoid mistakes.

2. Please pay attention to the temperature of the rechargeable type. In addition to prompting the battery temperature and not charging in a high temperature environment, the mobile phone itself also has to take protective measures, that is, it is best to put the battery side up, so that it does not contact the flat surface to facilitate heat dissipation.

3. Playing with the mobile phone while charging not only harms the battery, but also the radiation of the mobile phone will become larger, causing harm to the human body.

Contraindications to battery use]:

1. Do not use a broken battery, a broken battery is very likely to occur, even if it is not, it will damage the mobile phone and cause a short circuit in the internal components of the mobile phone.

2. Don't use your mobile phone to talk for a long time, a long-term call will not only cause the mobile phone battery to heat up, but also cause the internal circuit and earpiece of the mobile phone to heat up, which is very easy to cause.

3. Try not to hit ** when charging, when charging, the mobile phone battery will generate heat, then we continue to use it to hit **, the heat will increase rapidly, and it is easy to cause danger.

If it is a newly bought battery, this situation occurs, or very undesirable, there is no problem with checking the charger and data cable, and then it is recommended that the landlord go to test the battery at that time, it may be a problem with the mobile phone or battery.

It is very rare for a new mobile phone to be fully charged, if this happens, you have to send it to the after-sales service, there may be a problem with the battery or charger, replace it first, this situation is very abnormal.

The new battery is definitely more durable than the old one, but care should also be taken care of.

Precautions for mobile phone battery in daily use:

1.It is recommended to use the official standard charger to charge the battery to ensure that the charging voltage is stable and meets the standard.

2.Theoretically, keeping the battery in the middle range of power for a long time (around 50%, such as 30%-70%) is more conducive to prolonging battery life, therefore:

It is recommended to unplug the phone in time after it is fully charged, as the phone will be in a high power state for a long time, which will cause the loss of the battery to accelerate.

Try to avoid waiting until the battery is below 20% charge before charging the battery, as over-discharging can cause the battery to wear out faster. It can be charged as you go to prolong the life of the battery.

It is recommended not to leave the phone idle for a long time, and the battery should be fully charged from time to time. If the phone is not used or charged for a long time, the battery will be completely consumed, which will lead to abnormal charging or failure to charge.

3.A battery temperature that is too high or too low will affect your phone's battery life, therefore:

Try to avoid placing your phone in an environment with low temperatures, high temperatures, or large temperature differences.

Try to avoid using your phone while charging. Using the phone while charging can easily cause the phone to heat up, and discharging it for a long time at high temperatures will exacerbate battery loss.

Summary. Hello dear, one-time full good.

Under normal circumstances, the charging time is about 5-6 hours, so that the battery can be fully charged, and then the use can be slightly longer. Charging during the day allows you to better control the time. After the battery is used for half a year, it is recommended to charge the battery once a month, and then charge the electric vehicle battery after deep discharge, and the time is controlled at 12 hours.

This will be of great benefit to the power recovery of the EV battery.

It's better to charge the battery every time, or not to fill it up.
