Samsung U4 charging problem, Samsung rv415 battery won t charge

You use the charger to see if it can be charged, if the charger can't be charged, then the battery in *** is broken. Generally, two or three hours are fine.

It's possible that I didn't connect. Some have to drive. Please try it with a charger.

I believe there should be no bad. Generally, the battery can be charged for 12 hours. Rest assured that the charging will not be broken.

Eighty percent is a long time to charge! Otherwise! The lithium battery is broken!

Samsung RV415 battery not charging can be ruled out by the following methods:

1.Check whether the socket can supply power normally.

2、.Then verify that the light on the power adapter is on.

3. If the socket and power adapter are all free of holding problems, and the battery still cannot be charged, replug the battery and observe (if it is a built-in battery, you can use a pin to prick the battery hole at the bottom of the machine).

Samsung Group is the largest conglomerate in South Korea, including 85 subsidiaries and a number of other legal entities, and has established nearly 300 legal entities and offices in nearly 70 countries and regions, with a total of more than 200,000 employees, and its business involves electronics, finance, mechanical sales, chemicals and many other fields.

Hello: According to your description, the charging recommendation for a newly purchased mobile phone:

1. Charge for 2-3 hours after the first three full charges, and then use it after each full chargeNote: Do not charge the battery after the power is completely exhausted, it will affect the battery life.

2. Do not use the mobile phone for a long time during the charging process, please wait for the charging to be completed before using and operating the mobile phone.

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

1. 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.

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 replenished every other month.

After the phone display is full, it can be unplugged after charging for another one or two minutes.

It should be a compatibility problem + a slight difference in performance indicators, which is combined to create a strange phenomenon for you, specifically an adapter, a data cable, and a mobile phone, between the three. The following situation is for reference, which may solve your problem:

I have also encountered a similar situation, the process does not say, just talk about the result, my original parallel charger (input is 110-220V, but Europe is basically 110V) by the multimeter test output voltage is a little lower, can not bring my mobile phone, but the same charger, another data cable can be charged, found that the feet of the data line are different, it is estimated that the minimum voltage of the charging of another foot can be slightly lower, or it may be that the resistance voltage of another line is reduced a little.

The same cable can be used in other chargers, probably because the output of other chargers is slightly higher.

Attention: the similarities and differences of the output voltage of different chargers, the similarities and differences of the charging feet of each data line, the resistance and voltage drop at both ends of the charging feet of each data cable, understand these similarities and differences, and you will know your answer.

If the phone cannot be charged without increasing the battery level when charging, please try:1Use the original charger and data cable to connect to the power supply for charging.

2.For mobile phones with detachable batteries, you can turn off the battery and use a cotton swab to clean the battery contacts and the charging port of the mobile phone. If the above methods do not solve the problem, please bring the purchase invoice, repair card and machine to the Samsung service center for inspection.

Hello !

Your Samsung S4 phone charging problem.

Actually, it's not a problem with the machine; It's not a battery problem, it's just a problem with the power management display, but any chip machine has a chance to appear.

You don't need to worry!

With the original charger, it can be charged for 4 hours.

You can also charge your phone with the next 360 Power Saver, which can not only be fully charged, but also help your phone save power and extend battery life.

You should also pay attention to the features that are rarely used on weekdays, such as Bluetooth, GPS, GPRS File Transfer, WLAN...

Hope this helps you!

The current batteries are all lithium batteries, and there is no previous memory function. Now the recommended practice is to charge as you go, keep the charge above 20%, charge it when it is less than 20%, and fully charge and discharge it once a month, which can extend the battery life.

Typing is not easy, if satisfied with the answer, thank you!

If your phone won't charge, we recommend you try it as follows:

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.

Hello dear Samsung users:

Based on 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 contact of the socket.

3.If conditions permit, it is prudent to 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.
