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:

Reducing the battery consumption

Galaxy Note 3  provides options that help you save battery power. By customizing these options and deactivating features in the background, you can use the device longer between charges:

  1. When you are not using the device, switch to sleep mode by pressing the Power button.
  2.  Close unnecessary applications with the task manager.
  3. Deactivate the Bluetooth feature.
  4. Deactivate the Wi-Fi feature.
  5. Deactivate auto-syncing of applications.
  6. Decrease the backlight time.
  7. Decrease the brightness of the display.

    Can I unplug the micro usb while pluged into electricity while my tablet is on. I get a message to unplug when I turn it on if still plugged in, I also leave it plugged in while playing games if I’m on for hours, thank you?

    • Simon says

      you can unplug the cable at any time. Of course, it s better until the battery is fully charged. You got the message because the battery is fully charged. It is not necessary to turn off tablet for charging.

      you can also use the tablet while charging.

    i do a full drain by letting my battery run out of power
    then i do a full charge without switching on the device
    is that right cause sometime it gives me that 1% ..when i ll let for alittle while ut showes 2% ?
    So kindly what’s ur Advice ?

    • Simon says

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

      If your battery level is not accurate, you may use the battery until it’s less than 5% once in a while to re-calibrate the battery level.

    • Simon says

      For modern batteries, it actually is not as important as before.

      To be safe, you can leave it on the charger for a few hours after it is fully charged. If you need use the phone urgently, you can still use it whenever you want.

      The good practice is to charge of to full before unplugging.

      Also, the battery level msy be not accurate in the first a few days.

    • Simon says

      If the phone was shutdown automatically due to low battery, it may resume once connected to a charger.

      If your manually powered it off, you can charge it when it’s off. Of course, the screen can always be turned on to check the charging status.

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

    • Simon says

      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).

    if I left the mobile (note 3) all night being recharged . will that harm the battery or shorten its life time as it is being connected to the charger after it be 100% recharged without being unplugged for many hours ?

  4. Rajez says

    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.

    • Simon says

      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.

    My note 3 battery is discharging while i charge my mobile…its depleting fast while i am using it…and its not charging as fast as it should…pl help..

    • Simon says

      Did you use the bundled charger and cable? If you charge it from a pc or notebook, it can be slow, but normally it should be faster than discharging.

      If you have battery drain issue, you may install CPUspy to find out whether the phone can enter deep sleep state when not in use.

    • Simon says

      It should be fine. Actually, you should NOT completely drain your battery very often. It may have more damage to the battery.

      Normally, you should charge the phone when it’s below 15%. But each month, you may drain the battery to less than 5% once or twice to get more accurate readings of the battery level.

    My note 3 Is not getting charged like before it became vryy slow… my original note 3 charger i gave to my dad bcoz he was going for 4 days somewhere out … then i have brought my note 3 charger from outside i have charged my cell at night and in.morning i saw d charger was not working n it got spoiled like it got burned n my cell is also not getting charged now like before… now my dad also came n i checked with my origenal charger bt it’s nt getting charged… pleasee help me what should i do now???

    • Simon says

      if the battery cannot be charged, you may have to get a replacement battery. Please try to get the official one from Samsung store. Of course, you can try to remove the battery and try again. You may also try it with another usb cable.

      You should stay away from cheap chargers and cheap batteries. They can damage your expensive phones.

  7. blank says

    Is it normal that my tablet charges so fast yet it drains fast as well ?
    Or is it just my charger?
    Lately my charger have this strange circle like shape near the end part of the cable
    Should i change my charger to prevent this ?

    • Simon says

      You need check the charging rate for longer period time. For note 3,with the official charger, it should take about 2 hours+ from 5% to fully charged.

      You can check battery usage in settings – battery. What’s the battery life?

  8. keith says

    Hi, does the galaxy note 3 or note 4’s charger stop charging automatically when the phone is charged up to 100%?

    • Simon says

      You need check the battery usage at Settings–battery. You need check the screen time and the apps that drain battery. Please try to get some numbers.

      Battery usually can last 1-3 years unless you use the phone very heavily (e.g., charge it twice a day).

      The temperature depends on the ambient temperature and the apps you are running. Usually, you should not worry about it unless the phone restarts itself.

    Hi I just bought the Samsung Galaxy Note 4 Extra Battery Kit. How long do I need to charge the new battery provided with the kit for the first time?….Could you also advice how long to charge subsequently?

    • Simon says

      About 2 hours normally. There is an led indicating the status.

      The first charging time actually doesn’t matter too much nowadays. Once it’s full, you can discontent the power.

  10. Rick says

    I generally plug my Note 3 into my Linux PC for charging and data transfer. Is it necesary to unmount the Note 3 before I disconnect the cable? Thanks.

    • Simon says

      You should try to unmount the phone before unplugging the cable. The data writing is usually cached.

      It’s not a good idea to often charge the phone through pc due to unstable currents, which may result in inaccurate battery level reading.

  11. john mashauri says

    i have Samsung galaxy note 3 with 2 batteries i charged but it piss me off for sure i miss a lot of things because of out of charge, it show 1% even if i charge
    for 3 hours still keep showing me 1% this is crazy

  12. Carolynn says

    I’m just using a typical Samsung charger for the Note 3 and it takes 12+ hours to charge to 100%. Should I get a new charger …? Is this because the battery is bad or is it because of my charger? I’d want to know if the all-purpose charger with the micro thing would help.

  13. Eve says

    Is it better to charge it every so often I get the opportunity to charge it even if it’s still 50% or above or should i rather wait it until it drained below 20%?
    I heard it’s not good if the battery cycle is drained completely too often, but is charging it frequently when it’s not even half drained a better option?
    Will it make the battery shortened its life and eventually needs to be charged that often?

    • Simon says

      it is not good to charge the battery too often. If you know the battery is enough before you can put the phone on the charger, it is not necessary to charge it.

      anyway, when charging, wait till it is fully charged,

  14. Zay says

    Hi! My tablet has a problem in battery. I have drained it to 0% like trice this month. On the first one, the battery was fully charged to 100% I charger my tab when its in 5% below and its not anymore getting 100% it charged sometimes 92% sometimes 82%.
