Slow charging using USB laptop!

Hi guys. Is there anything that i could do to make my galaxy note 2 charging faster using a laptop? Charging using my laptop is soo slow! Help guys!

That is the limit of usb on a computer. If you want a fast charge you need to charge off the wall.

Wait for kernels that pump up the charge. (not recommended)

USB outputs about 900mA to charge devices with. Note 2 wall charger has a 2A output. Do the math.

If its a USB 2.0 port I think max is 500mA, USB 3.0 900mA

True enough; I just gave the maximum amperage you can get out of USB. Probably should have been more specific.

Something like this might solve your issue...
http://www.amazon.com/StarTech-com-USB2HAUBY1-Cable-External-Drive/dp/B0047AALW6
Not sure I would be willing to try it myself though.

Lol, yesterday I put it on charge at 20%, checked it after two and a half hours, and it was at 55%. I have USB 3.0 on my cabinet/MoBo, but just need to find out which one is it, but how do I do that?

This is a known issue on almost all Samsung phones that most people here aren't willing to acknowledge. The USB spec allows 500mA, but Samsung designs the recent phones to only pull 96mA. Apparently some of the modified kernels correct this.
Just be glad it's not like my old Samsung Focus. It would only pull 50mA which was less than the screen consumed. If the battery was totally dead, that phone was impossible to recharge via usb because it would auto-boot after you connected it, which would immediately consume the small charge it had acquired, thereby dying again.

Anything you charge off of a usb port will take forever.

Other brands of phone I've had seem to charge very quickly over usb. My laptops usb port will even give my ipad a full charge more quickly than my GS3.

Guys, try this. I have been using this for a few years now, works like a charm with everything, including iPads

Yes, that feature is included in a number of Asus devices, and it works really well. It's included in my Asus Sabretooth Z77 motherboard, and also on my Asus Diamond router (which has 2 USB sockets).

Why are you guys in such a hurry? I thought that it was best to charge the battery at the lowest possible amps - and the maximum should be 2amp/hour with the wall charger... so, as often as you can, charge the battery from usb, so that the battery lasts longer...?
- Bobo

Or just get a spare USB cable that you dont use to often. Short out pins 2 & 3 to force the phone into AC charge mode. You just wont be able to use that cable for data any more.
http://forum.xda-developers.com/showthread.php?t=767961

I was thinking about doing this or at least purchasing one online, but not sure what needs to be done, do I short out the CABLE or do I short out a USB port on a car charge? I read on a different thread that a guy who drives for 30 minutes, increased his charge from 15% (unmodded) to 30-31% (modded) and I think he did this to the USB port in his car charger, but not sure

I wish Samsung would just fix the problem to begin with.

If you're rooted I believe the Perseus kernel increases the USB charging rate to 900ma

Check Cable Compatibility

I ran across this helpful little app and thought it may help others to check there cables. All of my google cables checked out okay but the one C to USB cable I got at amazon was not compatible with my 6P. good thing it only cost $8.00
https://play.google.com/store/apps/details?id=net.mderezynski.checkr

Here's a write up Gizmodo did on what cables will work - http://gizmodo.com/a-google-enginee...source=gizmodo_facebook&utm_medium=socialflow

Here is a Google Spreadsheet of what compatible and what's not.
https://docs.google.com/spreadsheet..._sfNVNzbA/htmlview?usp=docslist_api&sle=true#

I've heard all about these 'compatible' cables, in fact I have one of the unsupported/out-of-spec cables and it seems to work fine. What are the consequences of me continuing to use this cable?

Cable or charger but not the phone? I thought with all this USB type c stuff it was suppose to 'intelligently' calibrate chargers and devices to prevent damage or an I thinking of something else?
Sent from my Nexus 6P using Tapatalk

yes when it's USB-C to USB-C, not when it's USB-C connector to USB-A which does not conform to USB-C specs. Makes sense?

Yeah OK that makes sense. Just seems like a step backwards in regards to acquiring and using cables. I'll now be hesitant of using any USB A-C cables that are are unknown or cannot be tested at the time.
Sent from my Nexus 6P using Tapatalk

I have an USB B to C adapter (2 pack) from D&K which, according to this app says it is fine, but according to the google doc's spreadsheet it does not meet the requirements. Hmmmm.....
My Orly 4 pack of USB A to C does not register as compliant which agrees to the spreadhsheet of compatible products. Wonder how accurate this app is????

Quick question!!! If the cable is not safe to recharge the cable is it safe to only transfer file into the phone ?

Good question. I'm not sure if its safe or not but I did transfer some files from my laptop to my 6p with no issues. But as soon as I found out that the cable was not compatible I stop using it. Didn’t want to damage the USB port on my laptop.

I bought two cables from amazon and one of them is probably out of spec - it rapid charges my 6p. But given its purpose (to quickly charge my phone from my anker power bank) I like the extra speed in charging. Any real harm in using it? The power bank is qc2.0 compliant so its used to having a large draw on it.

Thanks for this.

I bought a generic cable from eBay. I checked both the supplied USB a to C cable with the phone and the generic one. Both cables passed the test. However after about 3 weeks I ran the test again, now it is showing me both Google and the generic one fail the test.

Wall Charger with USB A and USB C ports

Is anybody aware of a wall charger that has both ports for USB A and USB C? I want to be able to charge my 5x along with my girlfriend's s6 at the same time, along with some other microUSB devices. It would be ideal for the USB C port to output 3A and the USB A port to output 2.4A. I've had no luck searching for anything like this.

I'm guessing this is maybe what you're looking for. Not sure if it can charge one at 3.0 and one at 2.4 but it does have both ports. Unfortunately since I am a new member I can't post a link but it's called the "Tronsmart 33W Dual USB Turbo Wall Charger". You should be able to find it if you search on google.

Good find thanks, definitely what I was looking for. Just a little expensive at $23...hopefully they start becoming more common soon.
Sent from my Nexus 5X using Tapatalk

Anker offer a desktop charger with one USB C 3A and 4 standard 2.4 A USB ports, total output 40W. Likely to be over budget though...o

There is the Choetech wall charger with 1 x USB C and 2 x USB A ports. It can do 1 x 3 amp and 2 x 2.4 A simultaneously.
It's reviewed here:
http://forum.xda-developers.com/nex...iew-choetech-39w-3-port-wall-charger-t3315872
I have the UK version and it works great with the 5x. Choetech cables (I have a C to C and A to C) are great quality. I think they make the oem cables for Google (I'm sure someone will correct me if this isn't right)

this one is also pretty good, just don't expect to be able to use all 3 ports at max output:

perfect for a phone, a smartwatch, and an accessory though

Does it really make a difference what kind of Type C cable you use? If so what is the fastest and best cable to use.

USB 3.1 will give faster speeds than the stock cable which is USB 2.0.
Of course 3.1 cables are more expensive.

And they are harder to find longer than 6ft.

no such thing as fastest and best when it comes to things that stick to an official spec.
usb spec is a spec all companies must adhere to. one company cant provide more or less than another if they are making cables that use the USB 3.1 spec.
if you want to take advantage of 3.1 usb speeds, look for cables that have the spec clearly on the cable and in the information.
for example, i use these, but there are many others that are also just a good.

They don't exist. They are rarer than Unicorns!

current usb 3.1 gen 1 cables that SPEC "10Gbps SuperSpeed" can only exist currently in cables less than 4 feet. this is the length the cables can be to stick to the spec (currently).
will no doubt change as cable tech catches up to make longer ones.

That's a bit much for charging a device. The cost of those cables are because of the converters on each end.
The best use for them is the Xbox One Kinect to extend its range of connectivity. I'm sure there are others though.
I do believe also that Android kernel does have a cap on how fast the charge is accepted on the device, to better keep the components and battery safe.

https://www.reddit.com/r/Android/comments/5b7ahk/study_critique_apples_rectangular_box_2m_usbc/
Look up benson, he reviews USB C cables and points out the good and the bad.
I have few of the apple USB c cables and they're on the recommended list. A bit costly at $20 but it's more of a universal USB c cable that you can charge devices up to 100w with it. (Apple uses it for their 87w MBP) I guess technically all of his approved cables fit the USB c standard and should handle high current fine but I'm just paranoid.

This right here!!
Been using these cables , powerline series ,for awhile. Almost indestructible, charge faster the stock cables and transfer better. 6 footers great , but 3 footers feel faster, must be 3.1 vs 3.0 . Can't go wrong with Anker.

@jason504,
In terms of charging, they are not different. As mentioned, the cable that currently ships with the device wont give you faster throughput than an aftermarket cable.
if you want to take advantage of faster data transfer speeds of the 3.1 spec, you are recommended to look into a 3.1 spec USB cable.
I use choetech but brand Cable Matters is also another good quality brand of cable. There are others as well...

Best USB - C Cable for Note 8?

Heyy guys. Can anyone suggest some good USB type C cables (3rd Party) which supports Fast Charging for our Note 8?
Do include those which comply with USB Type-C standards/ are compliant cables and are USB IF Certified.
Also please tell me how much maximum current does our Note 8 supports with Adaptive Fast Charge (QC 2.0).

You will not find anything that charges your phone faster compared to the cable and charger that comes with your phone.
I'm using a USB 3.1 Type C (Gen 2) cable together with the Anker PowerCore Speed 10000 QC which is a QC 3.0 charger and it doesn't charge any faster compared to the cable and charger that comes with phone. Both take about 1:30 to charge the phone from 20% to 100% while having the screen turned off.
