USB charging speed extremely slow

Hey guys, I just bought my One a couple weeks ago and I'm loving it so far. However, I'm having an issue with the USB charging speed.
I know USB charging speed is slower than wall charging speeds, but the speeds I have been getting are ridiculous. To charge my phone from 0-100 takes about 9 hours over USB when the phone is in sleep mode and not being used. Can anyone else tell me if they're getting the same kind of extremely slow USB charging speeds? Is this normal for the phone? I've been thinking about replacing it and seeing how the next one fares.
I'm charging in usb 3.0 port and takes 5h

I haven't timed it, but yes USB charging is very slow in general and especially on this phone. I've had several HTC Ones, and had the same experience.

Some Kernels have an option for fast charge which is supposed to help with it but certain usb ports only put out a certain amount of power. Also I know a problem with the OG note was with fast charge enabled a few charging ports burnt out (mine included). It was easy to replace them on that phone but this one will be more difficult if it does the same thing.
The problem is that the phone sees the difference between an AC charger and a usb charger. With an AC charger it can charge with a maximum around 850mA while with an USB charger it charges with an maximum of 500mA.
There properbly is a trick how to make the phone think it's on AC charger, while it's actually on an USB charger, and therefore charge with a higher current, but I haven't found out how yet.

Depends on the current battery level of the phone. Anything above 83%(somewhere around there), even on AC charger it will slow down to 500mAh at most.

Phone not charging nor with AC nor USB

Hey guys!
My phone will charge battery only sometimes. The PC usb is not charging the battery (but it does see the usb), my ac is not charging also. I bought a new one. not charging. I tried with 3 different batteries - not charging.
It only charge sometimes when im using the galaxy s2 mini charger. But then it charge ex to 50% or 80% and it stops. I get the charging animation but the battery power drops normally like if i were using the phone.
I opened my 9000 and tried to see if the usb charger is burned or the soldering is bad. But everything is all right :/
By mistake, when i was "rebuilding my phone" i put the simcard backwards. And then even with the mini2 charger i was unable to charge more than 1%.
Do you know what can cause it? Its not the custom rom (helly bean) because i did not update it when it happened a month or so.
Thanks for any help.

[Q] DK31 Dock charging time?

I want to buy the dock charger for my Z1 but there is no information about the exact charging time.i heard its 3000mAh @5v but because the dock only has a usb connector it means you have to connect it to the AC charger .and the AC charger is 1500mAh.
so if anyone can tell me the exact charging time on magnetic dock i would be so glad!

The dock has to plug into a wall plug for it to be used effectively. The wall plug determines how much mAh the phone will be charging at. 3000 i think is over the limit the phone can safely charge at...
I use a 2000mAh charger with my Z1 and the dock is connected to the stock sony 1500mAh wall plug and ive noticed its only slightly slower.

so you mean that it can charge by 3000mAh when its connected to the wall plug directly.is there any way to connect it to the wall plug directly? i mean is there any kind of USB to ac kit that doesnt limit the current ? because if we connect it to a charger(like the z1 1500mAh) it will be limited to charge the device at 1500mAh.so is there a direct kit or a 3000mAh charger should be used to charge it

Charging with the fast charger mainly overnight

Hey guys. So I Was wondering whether it damages the battery to charge with the fast charger. If so, should I charge with a standard charger instead?
I was also wondering if it is ok to charge the phone overnight with the fast charger.
Thanks!
Galaxy Note 5 includes auto-discharged feature, even with fast charger. I dont know clearly what your Galaxy Note 5 model is, mine is 9208. When I try to charge with cable charger or fast charger, my phone automatically discharges with all charger when fully charged and LED notification turns to green.
I have not tested with wireless charger so I have no idea.

USB Power Delivery Cable

Looking at this article it seems like an upgraded cable could charge a device faster. If the phone shows "Fast charging" can that be improved upon? Could a USB PD cable charge faster? Is the cable that came with the phone the best?
It is true that the cable intervenes with the charge the battery receives, but, in the end, there is a limit in the charge the charger itself can supply
I have used a couple of different USB Type-C cables that are said to be suppose to offer much faster charging speeds than the bundled stock Samsung Type-C cable. Honestly I don't notice a difference in charging speeds.
The real proof is always testing with a USB wattmeter and a phone that has less than 80% charge (screen-off).
The most I get out of a stock charging brick and a Anker Type-C cable is 18 Watts. Stock cable gives me 16 Watts under the above conditions
