The phone/pad's charging speed is slow

The charging speed of mobile phones and pads is intricately linked to ambient temperature and usage scenarios.
For your reference, here is more detailed information about the abnormal charging speed of your device:
1. Non-original chargers result in slow charging of your device. It is strongly recommended to use the official original charger for optimal charging performance;
2. Foreign matter or dirt accumulating in the charging port can lead to poor contact and consequently result in slow charging of the device. If you experience slow or intermittent charging, it is recommended to check the charging port for dirt or debris and clean it accordingly;
3. For your optimal experience and device safety, the charging strategy adjusts the charging current based on temperature fluctuations. Consequently, charging will be slower in both high and low temperature environments;
4. When mobile phones and pads approach full battery capacity, they enter trickle charging mode. During this phase, the charging speed decreases, which is normal and does not affect the device's functionality.
