The reasons for the slow charging of Samsung S8 are as follows:
1, the charging plug is not original: the use of inconsistent power of the charging plug to charge the phone, if the charging plug power is too small, it will lead to slow charging. If you use a high-power plug to charge a small power, the speed will be much faster, but it will cause great harm to the mobile phone battery, so please use the original charger when charging.
2, the ambient temperature is too low or too high when charging: in a low temperature environment, the low-temperature protection mechanism of the lithium battery will cause no chemical reaction of substances in the battery, so it can not be charged or the charging speed is slowed down, and at high temperatures, the lithium battery will be unstable and even cause an explosion.
3, Samsung S8 does not turn on the fast charging function: Samsung S8 is a mobile phone with fast charging and wireless charging functions, in the default mode, the phone will automatically default to non-fast charging mode. Fast wired charging is turned on or off in the advanced Settings in Battery options. 1. Turn off the mobile phone when charging: the mobile phone is turned on, regardless of whether the user uses it to do anything, its system background process will produce power loss, and turning off the mobile phone when charging can reduce the loss of this part of the power, so as to improve the charging speed of the mobile phone. 2, use the charger to charge as much as possible: the USB port of a desktop PC or laptop can provide very low power (5V voltage and 0.5mA current), obviously, the charging speed brought by such power is much slower than the dedicated USB charger. The safest, most appropriate and fastest way is to use the charger that comes with the phone to charge it. 3, the use of high-quality USB cable: USB cable will also have an impact on the charging speed of the phone. In order to reduce manufacturing costs, some manufacturers use inferior metal or very thin metal wires for USB cables, so they cannot effectively charge at high power conditions. Therefore, mobile phone users use a matching or relatively good quality USB cable to charge.
advice
1. Use the original charger to shut down and charge, and check whether the phone is slow to shut down and charge.
2. If the phone only charges slowly when the phone is turned on, please: (1) End the background running program (the latest application key in the lower left corner - End) (2) Uninstall the third-party battery management software in the phone. If the above operations do not work, see more solutions: (1) Check whether the phone has a version update and upgrade to the latest version. (2) Please back up the data in the phone and restore the phone to factory Settings.
