While charging, the device and the charger may become hot. During wireless charging or fast charging, the device may feel hotter to the touch. This does not affect the device’s lifespan or performance and is in the device’s normal range of operation. If the battery becomes too hot, the charger may stop charging.

 

 

Tips for charging Note9 safelyClick to Expand
  • When using the wireless charger, do not place foreign materials, such as metal objects, magnets, and magnetic stripe cards, between the device and the wireless charger. Especially, do not place cards such as RFID card , credit card, Door lock card between device and back cover. The device may not charge properly or may overheat and may cause damage the device.
  • Use only Samsung-approved chargers, batteries, and cables. Charge-related products affect a direct impact on the safety of the user, so be careful when selecting the product. Unapproved chargers including car chargers or cables may cause performance problems and malfunctions or damage the device which will not be covered by warranty.  
  • Using Non Samsung-approved products (eg. wireless charger, USB cables, car chargers, Micro USB Connector, USB power adaptor) that are not guaranteed to be compatible may cause damage to the product.
  • If the lower part of the device overheats, it could be because the connected USB cable is damaged. Replace the damaged USB cable with a new Samsung-approved one.
  • Be careful not to let foreign objects into the charger connector (connector, plug). It may cause overheating due to corrosion or temporary short-circuit of power terminal.
  • If you charge the device while the multipurpose jack is wet, the device may be damaged. Thoroughly dry the multipurpose jack before charging the device.
Why did my Note9 stop charging when battery is not yet full?Click to Expand

During charging, the device and the charger may become hot. And, if the device heats up or the ambient air temperature rises, the charging speed may decrease automatically.

If the battery comes to a specific temperature while charging, a charging algorithm to protect device overheating operates and accordingly the charger may stop charging. This is a normal operating condition to prevent damage to the device.

Wait for the device to cool down and then begin charging the device again.

Also, please check the charging cable for any damage as this could cause charging to be intermitent.
