There may be several reasons for the slow charging of mobile phones:
< br >
1. Problems with the charger or charging cable: If the charger or charging cable you use is of poor quality or damaged, it may cause the charging speed to slow down or be unable to charge. It is recommended to replace the original charger or charging cable, or buy a reliable quality charger or charging cable.

2. Aging cell phone battery: If your cell phone battery has been used for a period of time, there may be aging of the battery, resulting in slow charging or no charging. It is recommended to replace the battery of the mobile phone.
< br >
3. Software problems: Some mobile phone software may cause the charging speed to slow down or reduce the power. It is recommended to clear the phone cache or uninstall some unnecessary applications.

4. Charging environment problems: If your phone is charged in a high or low temperature environment, it may lead to a slow charging speed or reduced power. It is recommended to charge at a suitable temperature.

If your mobile phone is charging slowly but the power will decrease instead of increasing, you can try to replace the charger or charging cable, or clean the mobile phone cache, if the problem still exists, it is recommended to contact the mobile phone manufacturer or professional maintenance personnel for overhaul.
1. Please confirm whether you use the original charger and data cable for charging
When using unofficial chargers, data cables, or mobile phones to connect to a computer USB to charge, the amount of charge may be less than the phone's power consumption, resulting in less and less charging.
You are advised to use the Huawei official charger and data cable to charge the phone.
2. Please confirm whether there are foreign objects in the data cable interface or mobile phone charging jack, or whether the interface is loose and has poor contact
Before charging the phone, ensure that the charging port is clean and the port connection is stable.
3. Please confirm whether the phone is running a high power consumption program when charging
When the mobile phone is charging, it is easy to run high-power programs (such as taking photos, videos, games, etc.), which can lead to less and less charging.
If the preceding methods still do not solve the problem, back up your data in advance (third-party applications such as QQ and wechat need to be backed up separately), and take your mobile phone, charger, data cable, and purchase voucher to a nearby Huawei customer service center for testing.
1, the main reason is that the battery aging internal resistance becomes larger, resulting in slower charging.
2, the battery used by smart phones is lithium-ion polymer battery, this battery has a service life, the theoretical life of the general lithium battery is 500 to 600 times of cyclic charge and discharge, that is to say, the battery in the aging process of the battery is lower than the nominal capacity of 70% of the number of cyclic discharge.
3. In the aging process of the battery, the internal resistance of the battery is constantly changing, resulting in the higher the voltage of charging consumption, the smaller the charging current, and the longer it takes to fill the case of constant voltage.
4, a few tips to maintain the phone battery more durable.
5, the current mobile phone manufacturers are equipped with fast charging technology, now the charging time has improved a lot than before, generally more than an hour can charge our mobile phone to the full charge state, the speed is still very fast, so we do not need to shut down the mobile phone charging.
6, usually use a regular charger and data cable can be, usually want to charge how to charge, because the current battery does not have a memory effect, will not be as before in the constant charging unplug will have an impact on the battery power.
Lithium batteries are aging.
The reasons why mobile phones charge slowly and less are generally as follows:
1, insufficient output voltage when charging: long-term through the computer and other ways of charging, if the output voltage is insufficient will cause the battery charge less and less.
2, charging with non-original charger: this may cause overcharge resulting in battery power loss.
3, network signal problems: everyone should have such an experience, in the mobile phone signal is very poor when the battery consumption is very fast. One of the reasons for the poor signal is the old SIM card problem, the old SIM card is bound to wear a lot because of perennial use, and the worn SIM card will have certain problems in signal reception, signal reception problems will lead to the mobile phone itself is often in the state of Internet search, resulting in increased battery power consumption. In the end, the battery is not durable.
4, the battery itself aging failure led to a decline in capacity: the battery itself has a certain service life (normal use of cycle charge and discharge up to 500 times, with the increase of the number of capacity also decreased proportionally)
Charging may decrease rather than increase for the following reasons:
1, the mobile phone system failure, resulting in battery display problems.
2. The charger fails.
3, the charger and mobile phone contact is poor.
4. Cell phone battery problems. Cell phone battery problems are rare.
Mobile phone charging slow but power down because the charging power is not enough to offset the consumption of power caused by the problem, this situation is generally not the use of the original charger charging or third-party charging bank charging caused by the phenomenon, need to be replaced with the original charging
