Use the charger to charge the battery before using it for the first time. A computer can be also used to charge the device by connecting them via the USB cable.

  • Use only Samsung-approved chargers, batteries, and cables. Unapproved chargers or cables can cause the battery to explode or damage the device.
  • When the battery power is low, the device emits a warning tone and displays a low battery power message.
  • If the battery is completely discharged, the device cannot be turned on immediately when the charger is connected. Allow a depleted battery to charge for a few minutes before turning on the device.
  • If you use multiple applications at once, network applications, or applications that need a connection to another device, the battery will drain quickly. To avoid disconnecting from the network or losing power during a data transfer, always use these applications after fully charging the battery.

Charging with the charger

Connect the USB cable to the USB power adapter and then plug the end of the USB cable into the multipurpose jack.

When using a USB 2.0 cable, plug the USB cable into the right side of the multipurpose jack as shown in the image below.

Connecting the charger improperly may cause serious damage to the device. Any damage caused by misuse is not covered by the warranty.

  • The device can be used while it is charging, but it may take longer to fully charge the battery.
  • If the device receives an unstable power supply while charging, the touch screen may not function. If this happens, unplug the charger from the device.
  • While charging, the device may heat up. This is normal and should not affect the device’s lifespan or performance. If the battery gets hotter than usual, the charger may stop charging.
  • If the device is not charging properly, take the device and the charger to a Samsung Service Centre.

After fully charging, disconnect the device from the charger. First unplug the charger from the device, and then unplug it from the electric socket.

  • Do not remove the battery before removing the charger. This may damage the device.
  • To save energy, unplug the charger when not in use. The charger does not have a power switch, so you must unplug the charger from the electric socket when not in use to avoid wasting power. The charger should remain close to the electric socket and easily accessible while charging.

Checking the battery charge status

When you charge the battery while the device is off, the following icons will show the current battery charge status:

    • You need fully drain the battery only occasionally. The battery level number may be not so accurate, especially after a fast drain.

  5. Is it right that charging when battery is about 50% harms the battery?

    • I don’t think so. But once charging, you should wait until it is fully charged.

      Led is always on during charging. Red means not fully charged yet.

    • If the charger and cable are good, but you still cannot charge the phone. You may visit local Samsung service centre to have the phone checked. If could be faulty battery or the connector or some other hardware problems.

      Except water damage, in most regions, hardware problems added coveted under warranty (battery may only have 6 month warranty; other parts should have one year warranty).

  10. Hi.
    Usually when battery is low my note3 goes automatically to power saving.It disable many features like wifi,screen resolution,screen rotation ect. But once it’s fully charge it does not come back to normal features.
    Is it normal to re switch all after charge.?
    Thank you.

    • Automatic power saving was triggered in note 3 when the battery level is less than 5%. It changes the brightness of the screen and disable mobile data. But it should not change the resolution.

      You can always manually change it back at anytime, before or after the charging.

      Yes, data connection must be enabled manually. Brightness is not necessary.
