Mobile phone battery charging Annoyance, mobile phone charging problems

I think you may be using the old universal charger, there is a positive and negative conversion button on it, you correspond to the two electrodes on the left and right of the battery, if the charger's indicator light is not on, then you can press the conversion button, in addition, it should be noted that if your battery is put for a long time, the voltage is too low, even if the indicator light is clamped right, it will not light up, you can charge it for 10 minutes first, if it is not lit, then press the conversion button, and then charge a certain line, But only if you make sure that your charger is good. Otherwise, you can simply spend a few dollars to buy a new universal charger that automatically converts the positive and negative poles.

It may be two next to each other in the middle (the second and third), or it may be two on the side (the first and the fourth), you try these two, if the indicator light is on, it will be fine, and the indicator light will not be charged if it is not on.

Once you've found the right one, don't forget to mark it!!

One left and one right two pieces are fine, there is no specific one, anyway, after the clip, the charger light is on, there are no specific two pieces. If not, then you can clip the left and right pieces.

There will be positive and negative icons on the battery, so take a closer look around the battery metal sheet.

You can put the metal point of the battery against the point of the charger.

Points don't have to be the same.

As long as the dots on both sides are aligned.

I'll tell you!

The two most farthest two touches are the positive and negative poles. You don't have to worry about the ones in the middle. The middle one is used for mobile phone recognition. It has nothing to do with charging.

Draw a mark with a marker.

Generally, it only takes 2-5 hours to charge the new mobile phone line. Charging for 12 hours is a serious error.

The so-called first few charges of 12-24 hours is seriously wrong.

This theory is for the ancient nickel-metal hydride battery. Generally, mobile phones before 2002 mainly used this kind of battery, and now mobile phone batteries are all lithium-ion batteries or even lithium-polymer batteries.

NiMH batteries have a memory effect, and over time, there will be"Cell crystallization"phenomenon, which requires a long time of charging during the first few uses, and it is best to recharge after using the first few uses. As far as the industry is concerned, it is called full and full of release.

For lithium-ion batteries, this characteristic does not exist. So as long as it is full, it can be removed.

If it is charged for a long time, it will have a great impact on the life of the battery, in addition, when the mobile phone alarm is insufficient, it should be removed and charged immediately, and do not force it to be used until the mobile phone automatically shuts down, this practice will also accelerate the death of the battery!

This usage is called overcharge and overdischarge in the industry.

For today's mobile phones, there are two main ways: wire charging (direct charging) charging and dock charging (board charging).

The line charge is mainly suitable for business trips, the battery output of the line charge is very strong, and the current mobile phone wire charge is basically completely full in 2-4 hours.

The output current of the seat charger is low, and trickle charging is the main one. Therefore, the charging time is relatively long, generally 5-8 hours, but low-current charging is good for the life of the battery. So wire charging is suitable for emergencies when you only have one battery or are on a business trip.

The dock charger is suitable for everyday use.

Of course, the quality of the charger is very important, and for inferior chargers, whether it is a wire charger or a seat charger, their negative impact on the battery is self-evident.

The landlord's mobile phone is fully charged in 2-4 hours, and it cannot be said that there is a problem with the mobile phone battery or there is no problem.

However, there are many high-quality imitations of mobile phone batteries nowadays. So pay attention to distinguish between the real and fake batteries.

See details.

Apply best.

Probably not, just pay attention, try to use the automatic shutdown and then charge it every time, don't charge it before you run out of power.

Now the battery is basically a lithium battery, the memory effect is relatively small, the first charge is generally about 14 hours, the first three times of electricity is best put clean, so that the battery activity is better.

You use it without being fully charged on the second charge, there should be some minor effects, but the problem is not big.

Charging with a data cable will give people a bad problem, charging when using the computer, or charging when the mobile phone is connected to the computer, so that the battery is charged repeatedly, if it is too frequent, it will indeed affect the life of the mobile phone battery. Instead, charging directly on the power strip has the advantage (albeit the inconvenience).

Charging common sense:

It is usually the lack of battery life caused by incorrect operation, users often operate the mobile phone in the charging state, use non-original data cables for charging, charge when the power is empty for a long time, and often use the power bank to charge.

According to the above reasons, the user should eliminate them one by one and solve them one by one, so as not to cause fatal damage to the battery again.

Don't wait for the charge to run out to charge, the charging goes through first:

Constant current stage, at this time, the actual voltage of the battery is lower than the charging voltage (mostly, the battery voltage is increased during the constant current charging process, when it is increased to about 85% of the battery power is full), enter, constant voltage mode, the charging current is gradually reduced, the charging is about to be completed, and then enter, trickle charging mode, charging with pulse current, prolonging the battery life When the charger is charging, it is normal for the charger to heat up, but it is not normal to be hot.

The charging head and charging cable are not fast charging, and they do not match the mobile phone.
