1A charger vs 2A charger vs micro usb vs usb 3.0 - Galaxy Note 3 Q&A, Help & Troubleshooting

Hy guys,
so, i have a normal 1A charger with a standard usb to micro usb cable. It takes around 3 hours for a full charge.
I was wondering if i can reduce the charging time if i buy a usb 3.0 cable and use it with my 1A charger. Will i see an improvement in the charging speed? Do i need a 2A charger, and if yes, will it work faster with the normal cable i already have?
Thanks!
ps. my phone is on 4.4.2 with root

The USB 3.0 cable only improves data transfer from the computer to the phone, not charge speed. And yes, a 2A charger will charge faster but only if your current cable supports the 2A. If you have a generic, cheap cable it is most likely it will still only draw 1A of charge.

Thank you. So i probably need to get both the cable and the charger then.

Can I charge NExus 7 with a 5V 1A charger ?

Bought my Nexus in the US this summer, really enjoy this little beast.
I have a question regarding charging. The provided charger is a 5V- 2A charger but a US one. I have at home a HTC one X charger which delivers 5V - 1A. Can I use this charger ? What is the difference between 1A & 2A ?
Thx, Yves

I don't see how less amps would hurt it. It may not register a charge, or charge very slowly. I would wait for another opinion.
2A will charge faster than the 1A charger. That's the only difference.

On the flip side, can I use my N7 charger to charge my mobile (SG2)?
My SG2 charger is set for 0.7A, while the N7 charger is set at 2A.
Mine charges with the USB cable i use to transfer files, which is about 500mA. Works but slow.
checking around the net, that's what it say.
the USB port have a maximum of 500mA i believe. And i did noticed it tend to charge more slowly. While the provided Asus charger with USB port on it, it have 2000mA (or 2A). So i guess the Nexus 7 is made to be able to support up to 2000mA, while it will charge more slowly when connected to a computer's USB port.
I took out my PSP and its charger recently, and this charger is also 5V, 2000mA, except it's a round tip made to fit the PSP charging port.
I do have another 2000mA charger, it also have a round tip, luckily it fit on my Ainol Elf II tablet. I got this charger/power supply when i bought my HDMI switcher, it work without it, so it was sitting there for all this time, unused.
i'm gonna try charging it with the provided Asus charger now.

Yes. Your phone will not charge at the same rate as the N7, however.

Difference in charging speed with different chargers?

Hi,
I was wondering if using a 2A charger with a normal Micro USB cable will charge my Note 3 as fast as the same charger with a Micro USB 3.0 cable?
Considering that USB 3.0 only delivers a higher output compared to 2.0 when plugged into a PC, I guess it makes no difference when using wall chargers?
Am I right ?
Thanks in advance,
Ben
USB from a PC will always be less than a dedicated charger whether it is usb 2 or 3. A 2 amp charger is what I use but also pay attention to the lead as some are far better at handling higher currents than others as I found out trying various leads whilst running the app at https://play.google.com/store/apps...=organic&utm_term=galaxy+charging+current+apk

The phone detects if you are using a wall or usb charger, the second is considerably slower. Some usb chargers cheat to seem wall chargers so charges much faster.
What if I use a micro USB cable that is attached to a wall adapter plug, will it still charge fast on note 3?

Charging is not depend on USB 3.0 or 2.0, it acts differently only while transferring data. Otehrwise for charging both works similar.
The stock wall adapter has 2Amp output and I’ve a power bank with same output and the Power Bank provided with a short USB 2.0 cable and with both it takes same time to full charge. So no issues with the cable.

USB type C to USB A fast charging?

Are USB type C to USB A cables capable of fast charging? Or is USB type C to USB type C the only way of getting fast charging?
You can get somewhat fast charging on an A to C cable theoretically, up to 2.4A, however as USB Type A isn't rated at 3A you won't get the full speed of a true Type C fast charger. I found with many Type A 2.4A chargers though that none say fast charging, but that may just be because I'm using the cable that came with my 6P.
I bought this cable and plugged it into a USB 3.0 port on my pc. It delivers just as much juice as the stock charger. The two both charge at the same rate.
Updated. I'll add that USB 3.0 is capable of delivering up to 5 amps with the right cable.

I have the Play store Google cables and they won't rapid charge with my car rapid charger , but the Type-C to Type-C google cables will with same charger . So I'm thinking no but I don't have a AC rapid charger to confirm .

A USB 3.0 port on a PC can only deliver up to 900mAh. The stock charger is 3000mAh.

That is a big difference in mAh. It does rapid charge pretty fast though when plugged into my pc. It did not rapid charge with the cable Google provided though. I had to buy the joto which I showed above.

Does your phone say rapid charging? What does Ampere show as the rate of charge?
Before the car was broken into I had a Belkin 4 port charger and the A-C cord delivered fast charging just fine, the one it came with AND the third party cord I ended up using also, have a couple of Yoozon branded cords from Amazon
I have a-c cable, and tried charge it using a 2.0a power bank. It says charging rapidly. Is it save to charge this phone using power bank?

Yes. It says rapid charging. I'm not home now but will check what it says it charges at. I did grab a screen shot yesterday though. You can see by "USB debugging connected" that I am in fact plugged into my pc and it says rapid charging.
Connected to pc I get Max 1050 mAh. On stock charger I get 1850 mAh Max. So the stock charger will be about 40% quicker than USB 3.0. Guess one could just buy a USB C 3.1 pci card if they need it as fast as the stock charger

The stock charger is 3000mAh, so depending on how low your battery is (it charges at a higher amperage at a lower battery, and slower as it gets close to full), you would likely see 2500-3000mAh when charging a nearly empty battery, which would be 3x faster than a computer USB port. I'm not sure why it says charging rapidly though, that should only happen if it's above 2000mAh or so.

Maybe an extra pin being present tricks it(wild guess). I did notice the fluctuations in mAh and am glad to know that's normal . One thing I noticed in the app ampere is it said the port was capable of delivering 1800 so maybe it's just reporting wrong in marshmallow.

Can I use regular 2A charger with N6p?

There are no many adapters on the market and I couldn't find original huawei adapter. Can I use a regular adapter (samsung 2A for example) with my Nexus?

Yes, but you must use a certified cable. Check Benson Leung's reviews on Amazon to find a good one or use the cable provided in the box.
However you can buy original charger from Google Store or a valid alternative from Amazon like this:

If I understand correctly some articles USB A chargers doesn't support type-c power profile, so the phone will charge at a constant rate without lowering amperage to be gentle with the battery. Furthermore the quick charge is a very useful feature, so I suggest you to buy a compatible charger.
Absolutely. Just be aware that charging of the Nexus 6P/5X is limited to 1.5A over a proper USB Type-A to USB Type-C cable. With a USB Type-C to USB Type-C cable and a Type-C charger, it charges at up to 3A (as it does with the official charger).
So if you're worried about speed of charging, you may want to get yourself a new USB Type-C charger, as a Type-A charger will take about twice as long! (a 3A USB Type-C charger takes about 90 minutes) Personally, I just have a USB Type-A charger by my bed, since it will definitely finish charging while I sleep. Then I keep the original charger in my work bag, in case I need to quickly recharge during the day!

I don't know if that's the case, but if it is, I'm not sure it matters. With the USB Type-C charger it's drawing 3A and then lowers as the battery gets full, but I don't know how low it gets. Whereas a USB Type-A charger will be drawing 1.5A maximum, so it may not even need to lower.
Any good USB type A charger that you can recommend?
I Have a good opinion about Samsung adaptive charger that my wife uses with her note edge.
Sent from my Nexus 6P using xda premium
I am partial to Anker brand chargers. I would suggest the PowerPort 2 (as I own a couple), it is capable of charging two devices at up to 2.4A each (while the Nexus 6P can only draw 1.5A, iPads can draw the full 2.4A because of their proprietary tech). But as you can see on the Anker website, they have a ton of different options!

compatible charger

OK.... so i wanna know is it bad if i charge this phone with samsung adaptive charger ? and what about AUKEY USB-C Car Charger with 5V/3A USB C & Quick Charge 3.0?
My another problem is when i use oem charger my phone getting really hot like the back panel 110 degrees till almost 90% and then start cooling down, but i dont have this problem with samsung charger and my phone still charge pretty quick.
is anyone has the same situation?
The phone uses USB-C power delivery for charge spec. QC3 chargers don't work at all on my PH-1, seriously charges at .5amps. You're fine to use the Samsung charger or any other adaptive charger like Ankar power port chargers, they work fine.
Not sure about your phone getting hot using the stock charger though, mine doesn't do that.

So the phone will charge with an old USB Type-A charger and a Type-A to Type-C cable? What if it's not a QC3 charger like my Anker PowerDrive 2? I've read that some peoples phones charge slower than it uses power when using older chargers, but then some people say they charge ok, slower, but not that slow.

Yeah the power port chargers work just fine. Just not QC3 chargers, in my experience.
