Samsung s9 can't charge fast?


The main reasons for not being able to charge fast are the following:

1. The connection is faulty

2. Use non-original chargers and data cables

3. The fast charge option is not enabled

4. The software version causes the fault

5. The hardware of the phone itself is faulty

You can perform the following operations to try to fast charge:

1. Check whether the charging cable and the charging head are fully inserted. If they are not fully inserted, the fast charging effect cannot be achieved.

2. Check whether the original charger and charging cable are used. If not, please replace the original parts.

3. Manually turn on the fast charging switch: Settings - Battery - Fast wired charging - Slide on (or Settings - Power saving - Fast charging on).

4. Turn off the device or its screen while charging.

5. Check whether the mobile phone system has a new version and upgrade the system.

6. If the problem still exists, please bring the purchase invoice, repair card and machine to Samsung service center for inspection.


1. Yes, it is. 2. This is because Samsung s9 uses a relatively old fast charging technology, with a maximum charging power of only 15W, which cannot be compared with the fast charging technology on the market now, resulting in a slow charging speed.
3. If you need fast charging, you can consider using a mobile phone that supports higher power fast charging or buying a charger that supports higher power fast charging.
At the same time, you can also try to use a wireless charger for charging, although the charging speed is slower, but you can easily avoid the trouble of cables.


Check to see if the charging head is damaged, preventing the phone's fast charge protocol from being activated. Or your data line replacement caused by the inability to fast charge, it is recommended to use 5A data line
