Get to know how to charge the battery for your Galaxy Note 3, how to check battery status, and how to reduce battery consumption.
Back to Table of Contents
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:
- When you are not using the device, switch to sleep mode by pressing the Power button.
- Close unnecessary applications with the task manager.
- Deactivate the Bluetooth feature.
- Deactivate the Wi-Fi feature.
- Deactivate auto-syncing of applications.
- Decrease the backlight time.
- Decrease the brightness of the display.

Hi
my galaxy note N7000 takes a long time to fully charge and is heating near the camera area..
also discharging drastically after being charged..any help?
John says
Hi
I have a Samsung galaxy tab 10.1 tablet and the battery indicator is not working properly. It will take a full charge and drain at a consistent level but it will stay at 1% for a very long time. I have tried numerous things and with occasional use it will work for a day or two at 1% or stream a movie for 3+ hours at the 1%.
I have tried numerous times to ‘reset’ the battery calibration by fully draining it and charging it to 100%, turning it on and leaving it for 30 minutes then charging to 100% again and still no luck. Any advice on how to resolve this, it is extremely annoying since the screen dims out at 5% and it basically useless at that point
Thanks
Simon says
Vendors don’t offer any options for battery level estimation. If the battery is old, it’s hard to estimate the level. You can try to backup the tablet, then try a factory data reset.

donna says
my note is not charging properly and when I turn it on it drains fast and keep saying connected to port
Simon says
Did you try to reboot the phone to see whether it helps.
The messages can be due to dirty or failing USB connector. Sometimes, it can also be triggered by main board problems. You should visit local Samsung service center to check the hardware.

greatson says
how to fix it?
greatson says
why it is that if I off and charge my note 3 will automatically on? please reply,
Simon says
If you power off the phone, it should not on automatically. When you charge a powered-off phone, the phone charging status is on. You can check the charging status and battery level. But the phone should not be powered on.
Are you taking about something else?

fahad says
i bought it from someone. its not new. i dont know either the charger is original or not and original accessories are not available in my town. the charger gives different outputs with different cables. with the best avaipable cable it giver 1200 mA which i think should be 2000 mA
Simon says
All the info are printed on the charger. The original Galaxy Note 5 charger should be clearly marked as adaptive fast charging with a lightning icon. The output current is also printed on the charger.
The original charger has two output. One is 5v 2A. Another is about 9v 1.67A.

fahad says
simon i have note 3
plz tell me how much charging current is good for note 3
there are many apps like ‘galaxy charging’ that tells charging current. my chargr gives 1.2 Ampere. while on charger, output current 2 ampere is written.
Simon says
2A is the maximum current. The actual current the battery can take depends on many factors: the age of the battery cell, the percentage of battery level, and the temperature….
So, the actual current is NOT a constant. The system has some algorithms to control and optimize the charging.
For Galaxy Note 3, with the official charger, it should take 2-3 hours to fully charge it.

ranei says
my note3 phone shows everytime 100% battery level. when it normal use drain the charge and phone goes to switchoff without charge meanwhile battery shows 100% charge. what is the problem
Simon says
if the phone always show 100% level, something wrong with the system. You can try to remove the battery, wait a few mins and put it back again.

Chargr is orignal i thnk which is in box
Simon says
For the charging time, it should take less than 2.5 hours with the original charger. Did you check whether the cable is inserted tightly in both ends? You also try a new cable. Don’t use cables from headphone shops: get one from computer shop.
For battery drain, you need monitor it longer time, and check the battery usage details in Settings–battery. You need find out which app are draining the battery.

Ali says
Hey simon how much hours fully charged note 3 can be used easily?
Also my note 3 shows device status custom how can i solve this problem…and smart remote does not work on orient tvs and can this remote control air conditioner as well.?
Simon says
With the bundled charger, it should take about 2-2.5 hours to fully charge the battery. How long you can use depends on your usage and your network signal. Normally, most users can get about 4 hours of screen time.
If it is not official, in some regions, your warranty will be voided. You need check with local Samsung service center. Usually custom stats means you flashed the non-official rom, or you rooted the phone.
For the smart remote, if it does not, then probably the model is not supported. No, it does not support air conditioner.

swati says
hello..I have a note 3 neo phone that I bought some 8 months back..there was a issue in the motherboard so I had to get it changed…recently since the past 1 week..my phone has started heating up while charging and gets switched off in between, I have to take out the battery and switch on the phone again to make it work and sometimes the phone restarts itself on its own while charging. I dont know what is happening..I am using the charger that I got with this phone.
Simon says
Is this happened only when charging? If you use the phone heavily and continuously, does the phone restart?

My phone battery got drained completely overnight. This morning I have been trying to charge the phone but in vain. I tried different ports, tried charging with a portable charger, & also on my laptop, but still in vain. Even removed the battery & replaced back. Please suggest me a solution.
Simon says
Does the LED light after connecting the phone to the charger for a few mins? If not, you may have to visit local Samsung service center to check the connector and the board.

Pls help me out.
Simon says
For the battery issue, if it happens often, probably the battery is too old.
For the storage, it should show total storage, used and available as well. It should be 16gb or 32gb.

ajay lal says
My galaxy usually takes about 2 hrs to complete a full charge but now it takes about more than 6 hrs to comple even when my phone is not using . what is the reason ?
Simon says
Are you using the original charger and cable? Make sure the cable are inserted tightly in both ends.
Our Facebook page || Galaxy Note devices || Galaxy S8 Guides || Galaxy S6 Guides || Galaxy S7 Guides || Android Nougat Guides || Chromecast Guides.
ajay lal says
Yes i am using original charger and cable this problem arised before 2 weeks before that no problem was there it only take about 2 hrs to complete a full charge
Simon says
You may try other cable/charger. Also loose connection may also prolong the charging process.

Zain says
and is it save to put note 4 on usb cable chrging by my laptop?
Simon says
Laptop is not good for charging the phone unless it’s a usb 3.0 port. Some latest laptops may also have a charging port. Try to use these ports of available. When charging, you should wait till it’s fully charged.
If you have no other choices, you can still use laptop to charge the phone. But do not do it too often.

Zain says
ok ok last thing query
will it effect my battery if i keep my fone note on charge after it reminds me? and what is i put it afterwards and keep it using for a while?
Simon says
It’s not good. But it should not cause damages to the battery. If it’s convenient, you should disconnect the charger. Don’t worry too much about it.
But you should NOT use the phone too often when it’s on the charger. This may shorten battery life.
Our Facebook page || Galaxy Note devices || Galaxy S8 Guides || Galaxy S6 Guides || Galaxy S7 Guides || Android Nougat Guides || Chromecast Guides.
Zain says
I actually have a question not about note 3 but bt note 4 i hope it wont make any differnce because my question is about battery charging
i bought my note 4 day before yesterday but i did’nt put it on charge on first time but instead i used it whole night until it battery was drained to 25% and next day morning i put it on charge to upto 94%
does that have effected my phone or may it have caused my phone’s battery damage?
Simon says
Take it easy.
It’s not necessary to charge the battery before using nowadays.
When charging the phone, if possible, you’d better wait till it’s fully charged. But it’s ok if you have to unplug it earlier occasinally. Just don’t do it very often or everyday.
Our Facebook page || Galaxy Note devices || Galaxy S8 Guides || Galaxy S6 Guides || Galaxy S7 Guides || Android Nougat Guides || Chromecast Guides.
Zain says
so whats the proper procedure to charge the battery and at what time?
Zain says
and at what % i should put my fone on charge?
Simon says
Usually before 5%. The phone should remind you when reaching 15%.

Hi simon my question is after i updated my note 3 to lollipop version my bttry is easily to get drained..or it drained easily..is it nrmal?

Ralph says
To all those having issues charging their NOTE3 with the USB 3.0 cable that came with the phone. Use a USB 2.0 cable and your problems will go away. You may also want to try a third party USB 3.0 cable. It appears the Samsung supplied USB3.0 cable has some issues with the mating pins. There is nothing wrong with the phone port, it’s the cable that’s the issue. Hope this helps.
Carl says
Does anyone know how often you are aloud to charge your galaxy note 3 because I’ve had mine since the end of January this year and in the last week or so I’ve charged it 5-6 days in a row but don’t know how often it’s meant to be charged
Simon says
You can charge it whenever you need. It’s your phone.
But the battery has certain life span. Charging it too often may have adverse effects on the life span of the battery.
If you charge it daily, the battery should last about 1.5-2 years.
When charging, you should wait till it’s fully charged. Once it’s charged, unplug the USB cable. Also, try not to use the phone heavily when the phone is on the charger.

Hi simon..my question is i chrge my phone when its 30% and i alwys off the note 3 while chrgng but when its fully chrged the battery level it appears 99% when actually it shows 100%..are u fmaliar with this problem? is it my bttry prbz? Plz.hlp.tnx in advnce..
Simon says
It’s normal. I don’t think this is a problem. First when you start the phone, it will consume battery. Second, the battery level indicator is an estimation. Error is inevitable.
BTW, it’s not necessary to power off the phone when charging. A smartphone should not reboot so often.

Okie tnx.simon..:) so u mean its okie to chrge the note 3 open? Cz i more into off if i chrge my phne. Nd is it okie if it reach 30% do i need to chrge ot in tht lvel? Whts ur advice on this..30% is the proper lvl b4 u chrge ur note 3? Tnx.
Simon says
Smartphone is designed to be always on. You need power it off when you are not going to use it for long time.
It’s not necessary to power off the phone for charging. To save power, you can set shorter screen timeout.
Normally, you charge your phone after the battery level is less than 15%. But it also depends when you can access the charger again.
One important thing for charging battery is to unplug only when it’s fully charged if possible.
Do not use the phone for heavy apps when charging.
Unplug the phone once the battery is fully charged.

chris chai says
simon,is it playing games is harm for phone??
Simon says
I would say it is not a good practice to play games when charging. But a lot of people do it. As I know, it is not good for the battery if you often use the phone in this way.
Our Facebook page || Galaxy Note devices || Galaxy S8 Guides || Galaxy S6 Guides || Galaxy S7 Guides || Android Nougat Guides || Chromecast Guides.
chris chai says
no,i mean that playing games harm for phone?
i does not mean it is bad playing games while charging
Simon says
Games are just like apps. I don’t think games can harm the phone.
Of course, because the phone battery always have a life span of a few hundreds charging cycles or 2 to 4 years. If the phone is not used heavily, the battery can serve you 2-3 years. If you use it heavily, you may have to replace the battery after 1-1.5 years. Games usually consumed a lot of battery.
But this should not be a problem, because note comes with a removable battery. You can get an replacement battery easily. It’s not so expensive.

Stuart Levine says
Two questions: First, when I’m at the office, the first thing that I do when I get in is to put the Galaxy Note 3 on the charger (direct to the wall). I leave it there virtually the entire day. Is that ok?
Also, I will listen to the radio via the Galaxy Note 3 while it is charging. Is that a problem?
Simon says
Keeping the phone the charger is not a good habit. You should disconnect it once it is fully charged. You should connect the phone to the charger when you need charge the phone.
I think it is ok to listen to radio when charging. Try not to do “heavy” things (e.g., play games) when charging. But if you need do it, just do it. The phone has its own protective system if the temperature is too high.

How much time will note 3 neo take to charge its whole battery??my mobile is taking more than 3 and half hours to charge whole battery
Simon says
It depends on the charger. In most regions, the official charger has a maximum current output of 2000mA. So, it should take about 2 hours.
If you are using a charger with 1000mA output, it will probably take you 3-4 hours to charge.

MY NOTE 3 IF POWERED OFF EITHER MANUALLY OR DUE TO LOW BATTERY ( IF LEFT UNNOTICED AT NIGHT) DOES NOT RESTART … WHY?
Simon says
If you choose to power the phone off, you need start the phone by pressing and hold power button for a few seconds.
Restarting (shutdown + rebooting) only works if you choose to restart.

shahere says
I always off my note 3 after it charged and i will on it back after i wakeup. It is ok?
Simon says
It’s not necessary and it may shorten the life span of the phone.
Smartphones are designed to be always on unless it’s not used for long time. Too many power cycles may be not good for the phone.

Rene Perez says
Is there any way to charge battery of Note 3 faster and without harming this one? Thanks.
Simon says
The official charger with the original USB 3.0 cable is the fastest way to charge the battery. Charging too fast may damage the battery or cause fire.
In Galaxy Note 4, the fast charging (with the fast charger) is only for first 50% of the battery levels. This makes the charging time from 0-100% in Note 4 is only about 30 mins faster than that in Note 3. So, I don’t think there is not so much room for improvement based on current technology.

Rene Perez says
Thanks for this answer.
Mimi says
A week ago I bought a new Samsung Galaxy Note 3 phone. I plugged in the charger for the first time and then immediately turned the phone on and used it to finish the initial setup for about 5 minutes while the battery was charging. Only after that I read in the guide that I should have waited till it’s charged before using it for the first time. I, of course, turned the phone off immediately and only had it on when the battery was fully charged. Has the initial usage while the phone was charging for the first time harmed or shortened the life of my battery? I use the phone moderately, not too much, not too little and the battery lasts for about 2 days.
Simon says
Don’t worry about it. It’s not necessary to charge before using the phone. The battery usually have 50% capacity when leaving factory for you to test.
Just remember when charging the battery, you should wait till it is fully charged.

I charged my Note 3 to 100% at 10.15pm yesterday. In the setting, it shows 14 hours plus on battery. As of today, 12.45noon, the battery shows 20%. Normally, in the past 2 months, I only required to charge it once per 2 days. But now, it seems like I need to charge it within 24 hours.
Anything wrong with the phone or battery? Or what is the reason that cause the changes in the frequency of battery charging?
Thanks in advance
Simon says
Very likely, your phone failed to enter deep sleep state.
When you check the battery usage in settings – battery, it shows you how the battery was used (the percentage of battery used by each apps).
If you tap the chart, it gives more info.
You can then roughly figure out the possible caused of battery drain.
If you need help, take a screenshot of the 2 pages and share them with the community.
Of course, you can also just reboot the phone. It may solve the problem sometimes.

Cat says
In the setting, the battery now shows 8h 40 m 46s on battery. My last charging time was this morning 6-8am.
The breakdown of battery usage as below:
a) Android OS 41%
b) Andriod System 13%
c) Google play servive 6%
d) Screen 4%
and others less than 4%.
In the setting, under data usage, for periods 23-30 Nov, about 82.66 MB used. the breakdown as below:
a) FB 18.76MB
b) Google Chrome 13.89MB
c) Waze 12.39MB
d) whatsapp 7.49MB
and the rest below 7MB
So, in your opinion, what is the root cause of the problem?
I’m new smart phone user. How to reboot my phone?
Thanks.
Simon says
What are the battery left?
It could be just be due to background processes. You can tap the battery plot and then get more info on when the phone is awake with screen off.
Anyway, to reboot the phone, press and hold the power button. You should get an option on the screen to turn off or restart. Choose restart.

Sorry, I can’t recall last night battery %. But, now (Time 9.30am) it is 43% (10h 9m 0s). My last charging time was last night 9.15-11pm.
FYI, I restarted the phone this morning.
Also, yesterday I did 2 charging:
a) Morning 6-8am
b) Night, 9.15-11pm
Now, seems like I need to charge twice a day.
I’m concern on this.

Alexa says
I just got a new Samsung Galaxy note 4. So should I charge it for 12 hours?
Simon says
Not necessary, as I know. You can use it once it is fully charged.
Actually, the new battery should have about 50% battery. It is sufficient for you to finish the initial setup before charging it.
You may refer to this guide on how to maintain your Galaxy Note 4 battery (it was written for Galaxy S5, but it works for Galaxy Note 4 as well): http://galaxys5guide.com/samsung-galaxy-s5-battery-guide/

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%. What should do to make it charged 100%? I charge it from 10pm to 5pm so its like 7 hours. Thank you.
Simon says
Are you using the original charger and cable?

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,

Rohit Nayak says
My galaxy note 3 neo battery indicator shows 100% for a long time after i disconnect the charger. When i restart it, then it reflects the actual battery indication.
Simon says
Normally, you should not worthy about this unless it is not updated for more than 15%. The percentage is just a rough estimation and may be not real time.

Thanks a lot.
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.
Simon says
It could be due to the cable.
You can use usb 2.0 cable if you want. Insert it into right part of your usb connector on your note 3.

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
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.

stephen says
Is it advisable to charge even though the phone has still 5% charge?
Simon says
Yes, you should not wait it till 0%. You need reach that low level once or twice every month.

Andrew says
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.

sara says
My note 3 battery heats up fast and drains too. Should i change my battery ?
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.

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
Yes, the battery has its overcharging protective circuit.

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?

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.

Deanne Villanueva Lacuna says
Is it safe to charge a galaxy tab even if its not fully drained? Will it affect battery life?
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.

calen says
Do i have to charge my new note 3 for 8 hours before use?
Simon says
Usually it’s not necessary. But you can leave it in the charger for a few hours after it’s fully charged.

satinder says
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.

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.

mohamed says
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 ?
Simon says
Normally, this is not an issue. The battery has its own protective circuit to protect it from overcharging.

vince says
my note 3 wont charge, im not sure , but might have water
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).

Arjav Jain says
My note 3 does not charge when switched off.. it automatically switches on.
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.

esta says
Even when I manually turn it off. It comes on on its own immediately the charger is plugged.
Simon says
Not sure about this. But why do you need power off the phone?

julia says
My note 3 Led is always red even though the status on the screen shows charge 100% when the phone is turn on. But when I turn off the phone it just shows charging . It doesn’t show a picture of 100%
Simon says
100% is not charged. If your Note 3 battery is fully charged, it will show “charged”, and you will also get a notification asking you to disconnect the charger.
The LED color is usually reliable. If it is red, it means it is still charging.

busiri says
How many hours do I need to charge the battery for the first time
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.

Dr.Ahmad Fawzi says
Is it right that charging when battery is about 50% harms the battery?
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.

MSK says

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

how much time do samsung galaxy note3 took to be full charge ?

about 2 hours with official charger. If you are using it when charging, it may take longer time.

Ryan says
My note 3 is taking about 5 hours to charge using the OEM charger and cable. It just came back from repair to which they replaced the battery and updated the software. Im assuming from your note above that taking this long is not normal?
Simon says
It’s too long for the original charger. What’s the current output of the OEM charger? It should be printed on the charger.
Our Facebook page || Galaxy Note devices || Galaxy S8 Guides || Galaxy S6 Guides || Galaxy S7 Guides || Android Nougat Guides || Chromecast Guides.
Ryan says
2.0 Amps
Simon says
It should not take so long. Make sure the cable is connected tightly.
You may try a few more times and record down the time needed to get it fully charged.

I have a galaxy tab 3, 8 inch.
Mary Hart says
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.

Ann says
Is it true that you must fully charge a note 3 before unplugging or risk shortening battery life?

Just do not do it so often. You need make sure your Note 3 is fully charged a few times each month.

kunthea says
Well, I have one question to ask you.
I just bought galaxy note 3 for a couple days but here come the problem, when it reaches 20% the device will turns off.
What can I deal with this? Please tell me, thanks in advance
Simon says
Is it a pre-owned set? Did you check the battery? is it original? What’s the manufacturing date?
If the battery has been used for sometime, the indicator may be not accurate.

vaxhu says
Which way is it better, to charge my note 3 on or off ?
Simon says
You should not turn off the phone frequently as you may miss some important calls. It is also not necessary to turn off the phone often.
Normally, you leave the phone on when charging. Once it is full, unplug it. Try not to use it heavily (e.g., playing games) when charging.
