Long-term use of mobile phones should protect the battery and do the following:
1. Don't operate the mobile phone while charging, especially: watching videos and playing large games.
2. Do not charge with the original data cable;
3. If there is no electricity, charge it. It won't be long before 20% electricity is left.
4, do not often charge with a charging treasure.
5. Avoid using mobile phones in low temperature, high temperature or large temperature difference.
6. The charging time should not exceed 12 hour.
If it takes a long time to charge for the first time, it may be a battery quality problem if it is not used later, but as long as it is not changed, there should be no such problem. Close the application when not in use. .
Don't charge and discharge the battery in time, don't use garbage mobile power supply to charge the mobile phone, stop charging immediately if it is overheated, check the mobile phone, charge it immediately, use it immediately, don't charge it for a long time, don't use it for a long time, don't charge it.
Lithium batteries have nothing to do now. But in general, don't charge while using it, and don't connect it to the charger for a long time without taking it off. If possible, try to charge when it is time to charge (generally about 10-20% of the battery remaining), and don't always charge when there is a lot of battery remaining.

Check whether it is a new machine:
1, see serial number (IMEI)
Mobile phone serial number is the same as ID card, and the IMEI number of each mobile phone is unique. Generally speaking, it can be used to judge whether a machine is genuine or not. The discrimination method is as follows:
Enter * # 06 # in the standby state of the mobile phone, and a string of numbers displayed by the mobile phone is the serial number of its motherboard, so write it down; Remove the battery of the machine and look at the serial number on the white label in the two labels behind the fuselage, that is, the serial number of the chassis. The other label is generally the network access license. Whether it is consistent with the previous figures; Look at the IMEI number on the box of the machine and compare the three to see if they are all consistent.
If the serial number of the motherboard and the serial number of the chassis are different, then the machine is probably repaired or assembled. If all three serial numbers are the same and there is a network access license, it can basically prove that this machine is genuine. However, it is not 100% sure that the serial number of the motherboard can be written by computer and software, and the fake serial number label can be bought for a few dollars. For the sake of caution, we should continue to verify according to the following methods.
Note: The seventh and eighth codes of mobile phone serial number used to indicate the origin of mobile phones, but this method is no longer used to distinguish the origin of newly produced major brands of mobile phones. By analyzing the origin of mobile phone serial number to explain the quality of mobile phone, there is no theoretical basis at present, so please don't blindly follow.
2, look at the machine packaging and instructions.
The packaging and instructions of the regular new machine are beautifully printed. Nokia's high-end models are mostly printed on coated paper, and the fonts and images are clear and layered. However, counterfeit packaging boxes are mostly copied on simple single-sided paper, with rough fonts and images and blurred printing handwriting. Many instructions modified by informal channels are even plagiarized.
3. Look at the network access license
There is a watermark on the real network access license, and the color changes regularly; Most of the fakes are imitations, and the surface color has not changed. If you can't see it, you can also use ultraviolet light (money detector) to illuminate the network access license, and the real label will display the red "CMII" anti-counterfeiting logo. While the dummy pattern is blurred or not displayed.
The words on the real network access license are printed with a needle printer, and the numbers are clear. If you look closely, it is the dent made by the needle, while the fake network access license is printed by a printing machine, and the numbers are blurred and there is no dent. Generally speaking, it is difficult to fake the network access license, after all, the cost of counterfeiting is high. In addition, you can also check the authenticity of the network access license through online inquiry.
Step 4 look at the phone case
When you open the new machine, you will obviously notice that the "key parts" of the machine are covered with film for key protection, such as the inner screen, the outer screen and the camera. As long as the used mobile phone leaves traces. In addition, dust and traces of use are inevitable when renovating the machine.
The gap between the upper and lower casings of the machine, the gap around the keyboard and the charger slot are all places that are easy to "hide dirt and shelter evil people", and the rotating shaft of the clamshell machine will also leave traces of use, so special attention should be paid.
5. Look at the usage record and the running status of the mobile phone.
Look at the records of games, short messages, phone books, call records, homemade ringtones and other items in the mobile phone. If there are, most of them are not brand-new mobile phones. In addition, during normal use, the machine frequently shuts down or crashes automatically. It can be said for sure that there is something wrong with the motherboard or software of this mobile phone.
