The reasons for the slow charging speed of mobile phones mainly include: charger damage, charging cable failure, mobile phone interface damage or blockage, battery aging, mobile phone background program impact and other common problems, you can find out the problem by checking the relevant accessories and system use.
With the frequency of use of smart phone devices, as well as the long-term consumption of various software, it will lead to the situation that our mobile phone power is not enough, and it may also lead to the slow charging speed with the passage of time or some circumstances. Below, Zifan has sorted out the most likely reasons for the slow charging speed of mobile phones.
1. Charger problem. The simplest reason why phones charge more slowly than they used to may have nothing to do with the phone itself. Instead, you may have a bad power cord or adapter, or a weak power supply. In the same case, Zifang also recommends the use of the original priority charger, and in most cases wireless charging will be slower.
USB cables often appear, especially in homes with multiple users and devices. These cables often fall, bend, stay in positions where the temperature varies greatly, and even step on them. So before anything else, replace the cable and see if you can fix the problem.
Many people like to use ports on their computers to charge their mobile devices. This is not always the ideal solution, depending on the age of the computer and whether other ports on the computer are in use at the same time. All else being equal, you should use a direct source to charge your phone. In other words: Use a phone charger whenever possible
2. Interface problems. Your wires aren't the only element that can experience problems charging every day. There may also be some damage to the phone's charging port. Check whether the interface is blocked by corrosion or dirt. While this may not be the reason it takes more time to charge your device, you should at least rule it out.
To find the latter, use a flashlight to look around inside your phone's port. Remove any objects (such as cotton wool and dust) that do not belong to the port, and do not damage the components of the port.
3. Background applications. Phones that take a long time to charge also struggle to retain their charge while in use. A rogue application, or a general background application, may be the cause.
Both Android and iOS now offer tools that give you an idea of what apps are running in the background. For Android-based devices, check out Settings > Battery Battery usage menu. On an iphone, select Battery in the Settings app to see which apps use the most battery.
When you think you've found this annoying app, delete it and see if your battery life and charging speed improve.
4. Aging batteries. If you've used up the other tips on the list and the battery still seems to take a long time to recharge, you may want to consider replacing the battery. In late 2017, Apple was criticized for the way it handled aging iphone batteries.
The industry's little secret is that lithium-ion batteries don't last forever and can only be charged a limited number of times. Therefore, it may be the battery itself that causes the slow charging. Take your phone to an authorized dealer to learn more about replacing your phone's battery.
The charging plug is not plugged in properly.

Reasons: First, the connection line is connected to the virtual; Second, the charger output voltage is low; Three, the charger output current is small......
< br >
First check whether the connector plug and socket are virtual connections, and whether the connector is damaged. Secondly, check whether the charger and the electrical appliance match, if there is a mismatch between the charger and the electrical appliance, replace as soon as possible.
