[Q] Galaxy Note 4 slow charging

So I got a white galaxy note 4 last week and the phone has been working extremely good, but the phone today started charging really slow, like 5 percent in 30 minutes that's just a definitely a problem. I have taken so good of my phone and of the charger, the charger isn't damaged neither the phone and I don't know why is it charging so slow. I remember I use to have this happening to my galaxy note 3 and some days it charged slow and some fast and now it charges fast but why does this happen? I haven't change any setting from the phone or anything and is stressing me out.
I have power saving mode but still that ain't had nothing to do with the slowness, has anyone had this problem? I also haven't done anything to the battery, so I have no clue what it can be.
Any help please?

If the phone is within the 14 day return period exchange it for a new one.

Restart your phone and check if it is still slow charging. Maybe you have some "heavy" apps running in the background.

Flip the polarity of the wall charger. (Plug it in the other way. It fits both ways.)

Does Adaptive Fast Charging Come Pre-Enabled on the Note 4?

Was wondering, Does Adaptive Fast Charging Come Pre-Enabled on the Note 4? Or do we have to go to the Battery Settings first to enable it?

When I got mine, it was enabled already.

Oh, if your fast charge your battery once, does it reduce your battery's lifespan in the long run, or does it need to be fast recharged several times for a notable difference?

As a general rule, the faster you charge the battery, the hotter it gets. The hotter it gets, the more quickly it will degrade. I still use my S3 charger to charge the Note 4 overnight.
Does it really make a noticeable difference? From what I've read, probably not. But I don't think there's been much objective testing. Just using fast charging once is highly unlikely to affect it in noticeable ways at all.

If you've charged the battery once using the fast-charging method, is that going to impact the lifespan of the battery? Or does it take multiple fast-charges for the battery to begin to loose its charge?
Nowadays I use the regular 2amp Samsung charger that came with my Wireless Charger.

I edited that in right after I posted, but I guess you beat me to it. As far as I can tell, it's a gradual process. Unless the phone seriously overheated during the one charge, it shouldn't have much effect at all.

Thanks, looks like I don't another one of the Fast Adaptive Chargers after all, haha.

Honestly I'm not sure if it diminishes battery.
I have to take it off because I'm using a Zerolemon battery and it doesn't charge all the way up unless the fast charging is off.

The adaptive charging is built in as long as you're using the included charger. It charges at a higher voltage so it's not as damaging as say, a 3 amp charger would be, but it takes many many fast charges to affect the battery's performance. Generally speaking though, the faster you charge the more capacity you lose over time, but the worst thing you can do is charge it &leave it plugged in for hours fully charged. I use an old Bluetooth charger that's 500mah when i charge overnight & the fast charger at work or in the living room.

Fast Charge.

Is there a setting I need to enter to get the fast charge rate to turn on? I am charging the Note5 and its rate is at 425 mA with the screen off. My Note 3 Charges at 1800 mA with the screen off. I've switched outlets to see if it would help, but no.
How's everyone else's charge rate?

It's automatically as long as you using the Samsung original fast charger... Also check how long the full charge take.. Should be maximum 90 minutes

Try switching the charging cable with another. When I got my Note 4 I had a similar issue due to the cable.

Try turning your charger around in the wall. With my s6, it won't fast charge if the polarity is backwards.

Very true. I had some aftermarket much longer white cables, and they are SLOW. I just changed by Tab S to a shorter black cable that probably came with a charger I got, and it is charging normally. Odd that a cable can be slow, but it can.

I did not use it yet. How can i understand its charging first ?

Question S21 Ultra charging slowly with 25W charger

My S21 Ultra is taking 1 hour & 30 minutesh to charge from 5-100% with the Samsung 25W super fast charger and the cable supplied with the S21 Ultra.
And I have fast charging and super fast charging enabled on my device.
All the user reviews & battery charging tests online show that the S21 Ultra takes roughly between 1 hour 9 minutes to 1 hour 15 minutes to do a full charge from 0-100% with the Samsung 25W Super fast charger.
Any idea what is going wrong here? Is it an issue with the phone, cable, or charger?

Make sure you use official 25w pps wall adapter. I'm using electjet 65w 3 port adapter as it fit the best replacement for my needs. Its also a good value on amazon with fast shipping. Official samsung should work too but so far I get around 1 hr to full charge from 3% if i leave it alone.

Any suggestions on what I should do?

I've found that u should close all apps and just leave the phone alone it usually takes less than an hour for my s21 ultra to get 100%

I've done that. I've even switched off the phone at 5% & charged it. It takes 1 hour 23 minutes with the phone switched off to get to 100%.

Which 3rd Party Charger
Hi, i am just wondering, which Charger should i buy for the S21 Ultra, as i need more, i would buy them not from samsung. Do you have recommendations?
forum.xda-developers.com
You're charging it like it's a NiCad. Not great for the battery or for time.
Li's wuv frequent midrange charging and that can extent their life by hundreds even thousands of full charge cycles.

But that isn't the issue, is it? There is some fault here because of which my phone isn't charging as fast as other people's phones.
Regardless of the damage to my battery life, I should be getting the charging speeds that everybody else is getting with the S21 Ultra. Everyone who charges the phone from 0-100% gets a full charge in 1 hour 10 minutes. I'm trying to find out why that isn't happening with my unit.

What's the start temp at charging?
Is it exceeding 100°F when charging?
Have you tried another OEM 25w brick/cable?
Make sure plug is fully inserted into brick.
You tried clearing system cache, hard reboot and toggling the fast charging switch on/off 3 times?
Is there any case bulging?
If you're within your return window, get another one instead of going down with the ship.

The start temp is around 98°F while charging.
I have tried another Samsung 25W super fast charger and it still took 1 hour 30 minutes to get from 5-100%.
The plug is fully inserted.
There is no bulging of the case.
I've tried toggling off the fast charging switch & only enabled the super fast charging switch. It took 1 hour 37 minutes this time.

One factor that all of those YouTubers fail to mention is the temperature of the room that the device is in. Sure they take the temperature of the phone itself, but none of them take into account the room's temps. They don't seem to care about a more scientific approach, just AdSense payout.

The temperature of my room is around 30°C. Will it make that much of a difference that the charging time is prolonged by 20 minutes?

At 98F unless you cool it if fast charging* engages it will quickly reach 101F or so and then either ramp the charging rate down or stop charging altogether.
It's possible the battery is damage or the C port PCB is defective. Both will cause erratic fast charging.
*fast charging creates a lot of waste heat, fast.

I'm dreading to take the phone to the Samsung service centre as they almost always format the phone & I have around 400 GB of data in the phone. It'll take me a few days to restore the apps & data back to the phone.

Once the battery temp is at 98F you need to cool it. A damp microfiber cloth and a fan work well in dry climate.
You want the battery temperature between 85-95F for best fast charging rates. That's what I've observed. You'll get best results doing midrange partial charges to below 72% ie 40-70%

I'll try that.
However, I'll start doing partial charges only when I know that my phone charges at the speed that everyone else gets (0-100% in 1 hour 10 minutes). Wouldn't want to be stuck with a faulty phone.

Meh... that's why you always get an SD card slot.
No need to do that right away if there not going to replace it with a new one. Sellers give you a 10 day grace period usually. AT&T does.

Look they don't always fast charge at the same rate even when working correctly.
My latest charge log... this is at near ideal temperatures too.
You can see when charging in the midrange that averages about 2%@minute until 70-80% where it frequently starts to ramp down.

Unfortunately, the S21 Ultra doesn't have an SD card slot.
Also, I live in India where the Samsung customer service is absolutely terrible. Their only solution to all issues is to reformat the phone.

Yeah I know... that's for the next phone.
I did the same thing you're doing until I realized I could use the SD card as a data drive. No more 6+ hour reloads.
I doubt a factory reset will help but give it a shot before taking it in for service.
Just keep an eye open for any signs of battery swelling. If the charger and cable are good it's probably the C port pcb.

Question Mi 11 Ultra charging slow while gaming or using

Mi 11 Ultra is charging really slow when I play game or even do a normal surfing or using whatsapp
It's really irritating. Any fix for this.? Is it a software or hardware limitations.??
PS: Phone charges really fast when it is locked nd kept aside. Using indian variant and 55W charger that came with box

Its not 67w charger?
It could be a heat issue. If the phone is too hot, specially when gaming 3d it reduces the charging cause it has control temperature module.

In India we got 55W charger with box. And coming to the point, I agree during gaming it might charge slow due to heating issues. But during surfing nd whatsapp-ing if I charge then also it's god damn slow, do u face same issue.?? Can u pls confirm
When locked it charges really fast.

what is your ambient tempeture? it also affects it.
Thats the reason why some people get the 38min charging from 0 to 100 and others get 45min or more

It's 28°C.
I think the temperature of phone goes up during normal usage than when it is locked. I think that's the issue causing slow charging during normal usage. But I want to know if this an issue with the device or normal.??

That's definitely no issue! The Snapdragon 888 heats very fast and while charging even more. So there is no wonder it will reduce the charging speed to cool down while using the phone.
