Why does the Redmi Note 14 show fast charging when connected to the Samsung Travel Charger EP-TA200, but actually charges slowly?

To ensure optimal charging efficiency and device safety, it is highly recommended to use the Xiaomi standard charger that is designed specifically for the Redmi Note 14. Using third-party chargers, like the Samsung charger, will cause issues due to compatibility differences, especially when attempting to fast charge.
For your reference, the detailed explanation is as follows:
1. The Samsung charger doesn’t fully support the Redmi Note 14’s fast charging protocols, which can lead to slower charging speeds even though the fast charging feature is displayed;
2. The development team has been working on improving the compatibility with third-party chargers and has optimized the system to enhance the charging performance in the latest software version;
3. If you prefer to use the Samsung charger, please upgrade your phone system to the latest version. This will ensure better compatibility and help achieve more efficient charging speeds. For the best experience, however, using the Xiaomi charger is recommended.
