How long does it take to charge Samsung phone E848?

Normal, it will be charged in 2 or 3 hours.

Shutdown and charging In the use of lithium batteries, it should be noted that after the battery is placed for a period of time, it will enter a dormant state, at which time the capacity is lower than the normal value, and the use time will be shortened. However, the lithium battery is easy to activate, as long as it goes through 3-5 normal charging and discharging cycles, the battery can be activated and the normal capacity can be restored. Due to the characteristics of the lithium battery itself, it is determined that it has almost no memory effect.

Therefore, the new lithium battery in the user's mobile phone does not require special methods and equipment during the activation process. Not only in theory, but in practice, it is best to use the standard method of "natural activation" from the outset. As for the "activation" of lithium batteries, there are numerous sayings:

Be sure to charge for more than 12 hours and repeat three times in order to activate the battery. This statement that "the first three charges should be charged for more than 12 hours" is obviously a continuation of nickel batteries such as nickel-cadmium and nickel-metal hydride. So this statement can be said to be misinformation from the beginning.

There is a very big difference between the charging and discharging characteristics of lithium batteries and nickel batteries, and it can be very clear that overcharging and over-discharging will cause great damage to lithium batteries, especially liquid lithium-ion batteries. Therefore, it is best to charge according to the standard time and standard method, especially not to charge for more than 12 hours. In general, the charging method introduced in the manual of the mobile phone is the standard charging method suitable for the mobile phone.

It's normal. The first three charges should be more than 12 hours.

So just leave that full hint alone.

The first three times should be charged for twelve hours.

Don't leave it dissatisfied

Samsung's mobile phone is charged relatively quickly, generally you still use plug-in charging for the first three times, don't use the dock charge, the dock charge is not satisfied. For the service life of your electric board, I suggest that you must use the plug charge for the first three or four times, and the charging time is 12 hours to 15 hours, and too long time is also a damage to the electric board. My own board is well maintained, and it can usually be used for a week, hehe, I hope it helps you.

Hello: The mobile phone charging you consulted, it is recommended that you:

1.Samsung phones come standard with a lithium-ion battery source. Because the lithium battery does not have a memory function, it can be charged at any time, and can be charged and discharged shallowly. It can be used every time it is fully charged.

Note: Do not charge after the power is completely exhausted, it will affect the battery life.

2.Do not use the phone during the charging process, it is best to charge the slag cracked potato normally.

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.

The current charger generally has a full self-stop design, and 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 recharged every other month.

Welcome to Samsung's Digital Services platform.

If it is universal charging, it may cost six or seven hours, and if it is the mobile phone's own Heng Portable Charger, the class will be hidden in an hour or two! I hope it can help you, by the way, I am familiar, hehe.

Hello: According to the situation you described, it is possible that there is a problem with the phone battery in contact with the phone, or there may be a problem with the charger, it is recommended that you:

1.Take out the mobile phone battery, clean the battery contacts, reinstall the charging stove and check the power consumption;

2.Replace other batteries to see if they can be charged normally, and check the power consumption;

3.If the problem persists, it is recommended that you check whether the charger you are using is a Samsung original charger and connect it to a fixed power supply to charge to see if it is normal;

4.If the problem still exists, it is recommended that you bring the mobile phone three packs of vouchers and send the mobile phone to the nearest Samsung service center for testing

Have a great day!

Because the lithium-ion battery does not need to consider its memory effect and residual power, when charging it, it is usually charged for 5 to 6 hours by charging the battery with 15% to 25% of the current value corresponding to its nominal capacity.

For the batteries of various brands of digital cameras, there are special chargers that will alternate current, and after they are rectified and filtered, they output DC low voltage to charge the camera battery, and in this process, there is generally a charging protection and detection circuit that matches the camera battery to work synchronously, and it can be automatically powered off after charging, which is conducive to the full filling of the battery power and prolonging the service life; Some SLR cameras also have a dedicated charging detection and control circuit for their batteries, which cannot be charged without a dedicated charger.

The newly bought Canon 70d battery will generally have 20% 40% of the power, on the one hand, it is convenient for the first test of the new machine when it is purchased, on the other hand, it also ensures that before the new machine is sold, the battery has no power, and it will also cause damage to the battery, and the charging of it is also carried out using a special battery charger, and there is a good automatic charging, detection, overvoltage, and overheat protection circuit, so it can be used on the charger with confidence, and it can be completed in more than 4 6 hours. It is the same for the first time and for future daily use, because there is a special detection and control circuit to complete, so just plug the charger into the charging indicator color to green and keep it on solid.

Generally, it is charged for an additional 4 hours after being filled.

According to your questions, the standby time and usage time and usage habits, the standby length will change, and the strength of the signal will also affect the battery power.

If your phone has a short standby time, here are some things you can try:

1.Bluetooth, Wi-Fi, GPS, camera, browser, and other related applications, we recommend that you turn them off in time after using these functions.

2.It is recommended to set the automatic screen lock time to 15 seconds.

3.Adjust the brightness of the mobile phone screen according to the actual situation (the screen brightness can be lowered to save power).

4.If there is an external SD card inserted in the fuselage, it is recommended to restart the machine after removing it to test whether there is any improvement. Troubleshoot poor SD card performance.

5.Back up your phone's data (**book, SMS, multi** files, etc.), and restore the factory settings of Huaqin.
