SAMSUNG NOTE2 NEW PHONE HOW TO CHARGE? How long is the right time to charge? 12 hours?

According to your doubt, Samsung phones come standard with a lithium-ion battery. Because the lithium battery does not have a memory function, it can be charged at any time, and can be charged and discharged shallowly. However, do not overcharge the battery.

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.

Do not over-discharge. When the device prompts "low battery", 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.

I hope the above reply can help you and have a great life!

Today's batteries are lithium-ion polymer batteries, and the advantage of this kind of battery is that it can be used as it is charged, and it does not need to be fully charged or used up to flush, and lithium-ion polymer batteries do not have the first three charges12

More than hours of saying, this is the theory of the previous nickel-metal hydride battery era, the current battery can be used when it is fully charged, and half of it can be charged at any time, rest assured that it will not break, I have made this battery before.

Know some, hope, thank you!

It takes about 13 hours to charge for the first time, and it seems to be charged three times.

Try not to overcharge it later.

Now lithium batteries don't have to be charged for 12 hours, plug and charge, no problem.

No, just charge as you go, it doesn't matter how many times you first do.

12 hours of ** is the early nickel-cadmium battery, because nickel-cadmium battery is suitable for low-current charging, generally 10 hours can be charged almost, 12 hours can be almost full, plus the memory effect of nickel-cadmium battery is very large, not full of light, has a great impact on battery capacity. This classic saying has been handed down, and some people still believe in it in the era of lithium batteries. In fact, the memory effect of lithium battery can be ignored, and compared with nickel-cadmium batteries, it can also be charged with a larger current, with the original direct charge, generally a few hours is enough to fully charge the battery, and long-term plugging in the charger increases the danger of charging bad batteries (although there is a protection circuit, but it cannot be said that it is absolutely foolproof), so the mobile phone lithium battery, you can charge it with it, and use less inferior universal charging.

To add, lithium batteries do not need to pay attention to any activation matters, just charge and discharge normally.

Hello, it is not recommended to charge until the battery runs out, and it is not recommended to charge when the battery runs out. Because the lithium-ion battery of the mobile phone has been activated at the factory, it is not necessary to activate the battery with the first few full charges. At the same time, the deep discharge of the battery has a great impact on the battery life, so don't wait for the phone to turn off after it is out of power before charging.

Good luck.

According to what is written in the manual, see if there are any requirements, theoretically, lithium polymer batteries have no memory effect, so there is no need to charge them after they run out

Lithium batteries do not need as long as there is a prompt that the power is low, you can charge it, and you can unplug it when the charging is completed, overcharging and overdischarging will cause damage to the lithium battery, and let the machine automatically power off will also cause damage to the hardware of the mobile phone.

No, now the phone is a lithium-ion battery with no memory effect and can be charged at any time.

In the past, nickel-metal hydride batteries had a memory effect and needed to be recharged after they ran out.

The theory is not needed, because it is a lithium-ion battery.

Considering that you can't get over it, it is recommended to charge it for 11 hours.

Now the lithium battery of digital products will generally be activated and charged at the factory, as long as it is not a product that has been in stock for a long time, when you buy and use it, you generally do not need to activate it again, so the first charging time is not so particular.

Now lithium batteries are advanced, and there is no such thing as having to be fully charged for 12 hours. Rest assured.

This is just for the maintenance of the battery. Let the battery last longer.

Today's mobile phones are lithium batteries, and there is no so-called reason for how long to charge for the first time, and those are all old-fashioned batteries in the past.

A normal full charge is sufficient, and it does not need to be charged for dozens of hours.

Hello: According to your description, it is recommended that you try the following:

1.Shutdown charging test.

2.Replace the charging position to eliminate slow charging caused by intermittent socket contact 3If conditions permit, replace the spare charger for testing.

4.When the phone is turned on and charged, if the mobile phone is equipped with a third-party plug-in such as a charging doctor, it is recommended to test it after uninstalling it.

5.Check whether there are foreign objects in the charging interface of the mobile phone, such as liquid ingress, debris that causes the charging port of the mobile phone to be in poor contact with the charger and causes slow charging, if this situation is recommended to be repaired as soon as possible.

6.Back up your phone data (Book, SMS, etc.) and factory reset your phone (Settings - Reset - Factory Reset.

If the problem persists, it is recommended that you bring the purchase invoice, repair card, mobile phone and charger to the local Samsung service center for detailed testing

Welcome to Samsung's Digital Services platform.

It is recommended that you change the battery and charger to try, it is very likely that there is a problem with the battery, my mobile phone is generally fully charged in 2 and a half hours, and the standby is not as power-intensive as you said, the standby is about 2% at most a night.

Hello: According to your description, Samsung Note2 series mobile phones use ampere special chargers, with fast charging function, and the charging time is about 2 hours. It is recommended that you try the following methods:

1. Use the original charger to connect to the power supply.

2. Try to replace the data cable (eliminate the data cable problem).

3. If there is a spare battery, please replace the battery try (to eliminate battery problems) If the charging is still slow after the above methods, then please bring the purchase invoice, three guarantees voucher and mobile phone, power charger to contact the Samsung service center for testing by the engineer.

The charger is not original, the voltage of the non-original may be relatively small, the flush is slow, and it may be a problem with the mobile phone.

Why a complete discharge??? After discharging the battery, the crystal will collapse, causing irreversible damage to the battery. Nowadays the battery is not so particular, the only thing to pay attention to is not to let the battery go below 10%.
