To fix slow charging, several practical steps can be taken:

• Check the charging cable and adapter for damage or wear. Using original, certified, or high-quality fast chargers and cables compatible with the device greatly improves charging speed.
• Ensure chargers and cables are securely connected and inspect the charging port for dust or debris; cleaning the port can enhance power transfer.
• Close unused background apps and disable connectivity features like Bluetooth, Wi-Fi, or mobile data to reduce power drain during charging.
• Use airplane mode or power-saving mode while charging to minimize energy consumption and speed up the process.
• Avoid using the phone during charging as heavy usage drains power and slows charging.
• Charge the device in a cool, dry place and consider removing phone cases that may cause overheating.
• If the battery is old or deteriorating, battery replacement may restore charging speed.
• As a last resort, a factory reset can eliminate software issues affecting charging.

Wired charging is generally faster and more reliable than wireless, and choosing the right charger for the phone's specifications is crucial for optimal results.
