Hello dear Samsung users:

It is recommended that you turn off these functions in time after using them.

2.After running the app, it is recommended to press the [Back Button] to exit, if you press the [Home Button] the app is still running in the background, resulting in the consumption of power and system memory.

3.Remove the phone battery, clean the battery contacts, reinstall the charge and check the power consumption.

4.Once you drain your phone's battery, try to recharge it.

Hello! Go to the after-sales service first!

If you can, get a new machine.

There is no warranty for flashing the machine yourself. Recently, if you buy a note4, there is a lot of refurbished machine. Or you buy a new battery (Pinsheng, Yubo this kind of OK, you don't need Samsung original) to try.

It only represents a personal opinion, don't spray if you don't like it, thank you.

Sometimes system bugs will cause such problems, you can flash the machine first.

Possible causes include:

Poor socket contact.

Third-party plug-ins and system exclusions.

There is a foreign object in the charging port of the mobile phone.

Aging mobile phone battery.

If your phone used to be able to charge but now can't be fast-charged, try the following:

Pay attention when charging:

1. Whether it is a new battery or not, you can unplug it and use it when it is full, generally it will be full in 2-4 hours, do not charge it for 8 hours to more than 12 hours, it will be harmful and useless;

2. When the mobile phone battery is too low, you should try to start charging in time;

3. The activation of the lithium battery does not require a special method, and the battery has been activated before leaving the factory. If you insist on using the circulating "first three 12-hour long charge activation" method, it won't actually work.

Pay attention when discharging:

Because the internal resistance of lithium-ion batteries is very small, it is allowed to discharge with high current, and at room temperature, it can be discharged for more than 54 minutes (more than 90%) with a current of 1C5; Discharge time more than 30 minutes; 2C5 discharge time more than 23 minutes; and allows for short-term higher current discharge.

Precautions for lithium batteries in the use of mobile devices.

1. Charge according to the standard time and procedure, even the first three times, first plug the charger (wire charger) into the power supply, and then plug the output of the charger into the mobile phone charging port (both on/off charging).

2. When the mobile phone battery is too low, you should try to start charging in time; Lithium batteries are the most vulnerable to damage in the case of over-discharge!

3. The activation of the lithium battery does not require a special method, and the lithium battery will be activated naturally during the normal use of the mobile phone.

Does the lithium battery have to be charged for 12 hours for the first three times? Do lithium batteries need to be activated?

For the "activation" of lithium batteries, many sayings are: the charging time must exceed 12 hours, and it must be repeated 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 all the serious formal technical materials I have consulted emphasize that overcharging and over-discharging can cause great harm 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.

In addition, the mobile phone or charger with lithium battery will automatically stop charging after the battery is fully charged, and there is no so-called "trickle" charging that lasts for more than 10 hours as a nickel electric charger. That is to say, if your lithium battery is fully charged, it will also be white charged when placed on the charger. And none of us can guarantee that the characteristics of the battery's charge and discharge protection circuit will never change and the quality is foolproof, so your battery will be on the verge of danger for a long time.

This is another reason why we oppose long charging.

The main power consumption of the mobile phone is the screen brightness, wifi signal, data traffic signal, GPS positioning function, system automatic update detection, turn off all the functions that are not commonly used, and reduce the standby power of the mobile phone.

Hello dear Samsung users:

We welcome your comments on our services.

Mine is the same I went to Samsung after-sales and said it was a problem with the software I went to it several times and said it so Wipe What software do you have?

According to your description phone charging recommendations:

1. Do not charge the battery after it 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.

3. 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.

4. 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.

5. 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.

According to what I use, no, the phone looks full, about three or four hours on the line, the battery will be damaged after a long time
