The slow charging of Huawei's mobile phone may be due to the following reasons:
1. Insufficient charger power: Using a low-power charger will lead to a slower charging speed. It is recommended that you use the original charger or a charger that supports fast charging.
2. Loose or damaged charging cable: Poor contact or damage of the charging cable will cause poor current transmission, thus affecting the charging speed. You can try to replace a new charging cable to charge.
3. Too many background applications: When the phone is charging, if a large number of background applications are running at the same time, these applications will consume the processing power and power of the phone, resulting in slow charging speed. You can try closing unwanted background applications to improve charging speed.
4. Aging battery: Mobile phone batteries are used for a long time and will gradually age, which may lead to slower charging. If your phone battery has been around for a while, considering replacing it with a new one may improve charging speed.
If the charging speed still does not improve after attempting the preceding methods, contact Huawei customer service or go to the authorized maintenance point for further help.
