What a cluster this thing is to charge...

The note is a disaster for me when it comes to charging.
If your battery is low and you start charging it but using it at the same time, it doesn't get worse, but it doesn't get better either i.e. actually charge the thing, it just holds its own.
I have got to say I am not impressed with this!

I am not facing such problems. Charging takes pretty long yes but not as bad as you said. A larger battery will of course need a longer time to charge. But I wonder sometimes too if it's the battery problem or the charger output problem and if there's a way to speed up the process.

I think it is more to do with the actual charger, seems like a trickle charge or something.
Yes if charging and using at the same time you would not expect it to charge as quick, but mine doesnt really charge at all, just stays the same.
My acer iconia will charge like lightning even when i am using it, smaller battery or not it still charges!
This was one of the things i was looking forward to with the note, but this slow charge seems to make it more or less the same as what I am used to.
I have the usb plug which comes with the kindle, might it do a better job?

If anyone manages to find a proprietary charger which can produce better charging I will like to know too

That is common the charging is very slow and if you are playing HD games then the charging is almost in negative. May be its because of the voltage of the charger inputs and it is to low. Samsung must have done it for a reason may be its because of the proprietry port or the battery itself we do not know but we need to live it

Agreed, charging this thing takes a long time. Keep in mind that the battery is 7000 mAh and the charger is most likely a 2 amp charger, pegging the charge time at around 4 hours with no other losses. So if you're using it, it should take even longer.

No such issue here. I charge to full capacity while using all the time.

I get what he's saying. Because it draws so much power when you're using it; having it charging at the same time doesn't move the needle much. For example, if you're watching a movie while it's charging you'll probably be at the same point battery wise when the movies over. People complain about this all the time when their using their devices as a GPS. In some cases not only doesn't it charge but it actually continues to drain so you're worse off from where you started. We're using 21st century toys powered by 20th century battery technology.

This is a better way of saying what I mean, thank you.
I also have to say one thing I do not like doing is turning the screen brightness down. After all we all get these things as they look so good, so I am not going to make it look worse when I am using it, what would be the point in that? Its a bit like saying yeah my battery life is 14 days but actually it is on standby for that time lol...
Anyway, I still believe it should be better and the primary cause is the weak charger for what ever reason sammy decided to make it that way, but its not a good thing.

It seems like I remember someone recommending a charger that was more powerful so the note would charge faster. Can anyone confirm this?

What a fail thread. If you know ANYTHING about charging, you would know why this happens and why this is NORMAL.
But why even search or educate oneself, let's post a thread on XDA and whine a bit.

It could be worse. It takes six hours to charge a N10.

I dont face this problem i charge mine when surfing the wep

On a slightly related side note, doesn't it suck that the brightness just turns down completely when the battery is low?

The zslower charge rate protects the batteries life ,reduces the possibilty of heat and battery damage trickling insures a full charge

if you don't want your screen to dim don't use the power saving setting.

For all those facing the slight unresponsive screen please change the source of power, I had mine connected to UPS power supply as soon as I changed and connected it direclty the problem was gone.
Even if you read the user manual of Samsung Note its says thats one of the reasons

How Manhattan hours per day do you use the note? With a 10hrs battery life I find an overnight charge is sufficient

Wow! many friends?
Anyway moving on.. so i just got my note 10.1 about a week ago, loving it but saw that while plugged in it was not charging at all while i was using the tablet and never quite getting to 100% overnight. By not charging while using, i mean to say that it was actually discharging. Yes of course i am using the stock charger and cable.. and even stock note.
so just tried something silly. Unplugged and plugged the usb from the block repeatedly about 5 times. Now its not only recognizing and charging, but charging relatively quickly even while using. To test, i unplugged for about 20 min and plugged back in. Same great results.
Just thought i would share instead of hoarding my new found knowledge like others..
Quick update: it charged about 10% in 20 min.. Nice

I don't charge mine - I paid cash for it

Overnight fast charging?

Hiya guys. Long time lurker but gonna pop that cherry today.
Was curious as to how many of you leave this phone fast charging overnight? I know its a smart charger and all that good stuff.
For an hour of charge i dont mind staying up for it since it prevents any damage that may happen. But i mainly do it to baby the battery.

i used the wireless one so it trickle charges and keeps battery in good condition. Fast charging will degrade it faster,

Do you have any proof to back this up?
I've had the Note 4 since January and have been fast charging it over night every day since then and I haven't had any issues whatsoever still running with excellent battery life. I'm now using the S6 Edge+ and wouldn't think it would be a problem. The power cuts out once the battery reaches max so it shouldn't try and fast charge a full battery.

It's a well known fact that fast charging is bad for battery condition. The electrodes degrade and corrode and the higher amps required for fast charging will contribute to the issue. I fast charge my note 3 and I'm on my 3rd battery now and this is starting to show decreased life.

Me too. My Note 4 was always on the fast charger and no obvious signs of deterioration. I am pretty sure Samsung has considered any issues, especially in a phone with a fixed battery, as they put Fast Charging very high on their list of selling point features.
.

I use my fast charger over night and have noticed when it reaches 100% the lightening icon that shows on the battery icon when charging goes away. So there must be some sort of electronic protection built into the phone

Of course it stops charging. Lol

Yeah. I still have the voice in the back of my head making me not let it charge overnight. The smart charger is nice to know it stops it from charging the battery, but still leaving the chance of having it fail in the middle of the night while its still connected to your phone is worrying to me. Even more that it pumps more voltage like a monster then any other wall charger i have.

Charging Problems

Is anybody having slow charging problems when the screen is still on?
A couple of days ago it took over an hour to charge from 5% to 25%, all I was doing was social media browsing. As soon as I put the phone down with the screen off the % jumped to 85% in around 30 minutes. I took my V20 back to the LG shop and in the end they replaced the unit as they could see the problem but was unsure what it was. They then tested the new one just before I was leaving and it was again taking nearly 90 seconds or more to charge 1% on the new device straight out the box. They went and give me a new battery and said to test it out for a few days before going back to them. It was there first complaint about the charging speed.
Again, while not using the device the charging is quick on the new device, but slow when the screen is on and in use. I will give it a couple of days and take some screenshots of the battery stats if it continue. It did say on my old device while connected that it was 5hr 45min until fully charged which is obviously wrong.
No weird apps on there that could be causing it as far as I'm aware, unless it's an LG pre-loaded one.
Strange that the new phone is doing the same.

Sounds like that's how the V20 manages battery charging. It charges faster with the screen off. And a lot faster with the whole thing off.

Same thing happens to me. When using Waze app. Even if it says fast charging, its noticeably slower than when i had my note 5 or 7.
Maybe its "heat management"? Im just guessing. Maybe to prevent it from heating fast with the screen on + quick charge

I think it's QC 3.0 - it does it so as to not overheat the battery. I have it happen on mine too when using a QC 3.0 charger.
When using a QC 2.0 charger(Samsung charger) it chargers a bit faster while screen on but the phone starts to get noticeably warm.

It is probably a thermal management thing. My N6 Shamu got very warm on QC2 with screen on.

The v10 does the same thing it's probably because the screen is the biggest battery drain on the phone so using it obviously would cause a significant charge delay.

Normal.

Hmm. I notice charging is slower when it's the temperature is higher.
I just bought a Spigen Rugged Armour case and I think it's trapping heat during usage. And when I start charging, it's not as quick as I had hoped.
I'm going to observe a little more.

Alright. I've done a few days of observations. It definitely charges a lot slower when the screen is on. I used the Ampere app and it charges around 900mAh max, screen on.
When it's off, it averages around 2800mAh, depending on temperature too. Once it hits close to 40 Celsius, it drops to 2000mAh or lower.
With the phone powered down, it charges faster than just screen off. How much faster, I am unable to measure without using some special hardware.
Overall, I'm quite pleased with the charging performance.

Turn your screen brightness down. Also I noticed restarting the phone helps with it to charge faster. Could just be a glitch in charging software

An observation on the slow charging fiasco...aka not fast charging

So, like most S8 owners herein, my device use to fast charge when I first got it....or so said the description in the notification bar. Recently, in the past few weeks, I noticed that it now only said cable charging. I was pretty irritated because fast charging is really desirable. Being able to top up rather quickly removes any concerns I have about battery life on the device, though admittedly it generally lasts me 24+ hours.
Anyway, I checked around in the forums and realized that many owners had this same issue and nobody seemed to have resolved it. Yes, some said use the original charger (I did, to no avail). Others said to confirm that fast charging was on (I did that also).
Then, I remembered reading an article about how the S8 doesn't actually fast charge when the screen is on. So, I wondered if maybe that's why I only saw "cable charging"...because the screen was on to see it.
As an experiment, I installed Ampere and left it running. Of course, while the screen was on, charging only measured about 1000-1100 mA. Yup, that's slow and confirmed my worries.
But then, what I did was to turn off the screen and wait a few minutes, while leaving Ampere running in order to see the max value. Surprisingly, and refreshingly, when I unlocked the device and checked the max value observed in Ampere, the S8 had registered a value of 2520 mA!
So, I think what's happening is that Samsung eliminated the fast charge notification because people were complaining that it wasn't fast charging when the screen was on. However, when the screen is off, it actually increases the charge. Alas, without the screen on, one cannot observe a fast charging notification.
At the very least now, I feel relieved to know that fast charge appears to be working. I'd be curious to hear what the rest of you think. Cheers.

This makes sense but my S8 still charges slowly even with the screen off. I'll try your test and see what happens. If I want it to charge faster, I turn the phone off completely. This very reason is why I ditched my samsung notebook. There was a system upgrade that disabled the ability of the device to charge while on. So annoying.

As I understand, that S8 enables fast charging when screen is off. With the screen on, it is slower.

Wow that would be really annoying on a laptop. I know they're stepping up battery safety but that's a step too far!

Yes from what I've read fast charging only works with the screen off, this is to limit the phone from getting too hot while fast charging and using your phone simultaneously.

As nice as the S8 is I really think everyone should just use oneplus`s dash charge. It's so great, filling the battery in 50 minutes... Quick charge is way inferior.

I think you hit the nail on the head. It seems that Samsung remains quite stung but the blowback from the battery issues surrounding the Note last year so they are taking NO chances with the S8.

Oneplus Wireless Charger Speed

Hi guys, I was lucky enough to get a free wireless charger with my phone from Oneplus.
Since then I have been testing the speeds and I am pretty surprised about how slow it is.
Now I realize that this might be faster than most wireless chargers, but I was wondering if you guys could post your times, ballpark, from either 50% to 100% or near dead to 100%. Something measurable.
My phone is at 4%, I put it on the charger and it says 1 hour and 43 minutes to full. Is that expected? Do yours show similar?

That doesn't seem right. Did you check your settings on the phone? My S20 Ultra with a bigger battery and much slower wireless charging takes less time to fully charge.

First from gsam after letting it sit for ~30 seconds to establish a good connection, and 2nd from ACCA. This is the charging current it states for me.

Unless there is a setting to turn on on the phone to enable fast wireless charging, and I don't think there is, it doesn't seem to be working correctly. I could try to plug the charger in another outlet. Not sure what other variables there are.

My charging speeds are also slower. Even slower then on my 15W Samsung wireless charger. Any ideas why?

I get fast charge with my Samsung fast wireless chargers. I going to return their Warp charger.
