After trying a few different roms and yesterday my N7 will no longer charge when connected to an AC charger, it still works when connected to a pc.
I'm using the same charger/cable that has been working for months and the charger works with other devices.
I have tried factory reset/wipes and full reinstall. I have also tried restored backups for a few days ago which no longer work either.
Any one know why it would work from pc and not AC? Could it be a hardware problem unrelated to rom changes?
your tablet charges through PC; are you using a USB slot hooked up to a higher power connector (i know some motherboards have those)
I've worked it out. The nexus AC charger has slide on pins for countries different GPO configuration, the head i had on the charger wasn't clipped in all the way and was causing the charger to work intermittently.
Hi,
I bought PowerGen 3.1A Wall Charger, when I use with original Micro USB cable that come with my Samsung Galaxy S4, the charging current is 1.9A, when I use with a generic USB cable, the charging current is only 700mA. (I have a way to test the charging current)
Does anyone know which Micro USB cable that carry fast current, such as 1.9A like original USB Cable that come with S4, or even better, carry up to 3.1A that this Wall charger provides?
Thanks All.

Faster charging is enabled in the kernel, not by a cable bro.
Hi,
you have to look for custom kernel with fast charging support. I am using faux123 with fauxclock app.

The Note 3 is the first phone to come with USB 3.0 support, the cable and connector are up to spec.
What I'm wondering if this helps with the charging speed, as the wall charger doesn't seem to be with a USB 3.0 connector.
Does anyone have any insight to this?

The wall charger has a 2Ah power output while a pc usb 3.0 port has a maximum output of 900mAh. If you use an USB 2.0 port it's only 500mAh.
The best way to recharge the Note 3 is to use the wall charger.

From a dedicated charger the final charging current is normally determined by the PHONE + CHARGER based on how the phone "recognizes" the charger as good/bad (and what battery level you already have + how warm the battery is) and how much power the charger can provide. I believe the max that I have seen on my Note 3 was 1800 mA (which worked with both USB3 cables but also with some good USB2 cables).
From a PC the charging current is the result of a more complex negotiation, the phone can still have "the last word" but it can not go over 500 mA on USB2 or 900 mA on USB3.
Somehow related - please note that on USB3 DATA you STILL need to MANUALLY enable USB3 mode EVERY TIME YOU PLUG TO THE PC. Even if enabled the mode will be reset to USB2 in 10 minutes and lost if you remove and plug-in again. That being said on my Thinkpad I have not seen it charging over 450 mA even when on USB3 under Win7 (but the speed difference exists, so USB3 is correctly triggered).
Also please note that the life of the battery can be heavily influenced by the charging current - the smaller the charging current the more cycles the battery will last on the very long term. Also high temperatures are pretty bad for the battery. So if you are in no hurry it is always better to charge with a small USB2 current that is guaranteed to not go over 500 mA.
Maybe I wasn't clear enough, I'm wondering if the wall charger is utilizing the USB 3.0 capability, and if there's any advantage of using the USB 3 cable over a regular micro USB cable.

No, there is not. The Note 3 has a USB 3.0 port, but it is only faster for data transfer. Charging is done at 2.0 speed, not 3.0. Regardless of what you attach it to, it charges just as fast as a 2.0 device.

What if you used a USB 2.0 cable with the 2Ah AC adapter? Would it still charge in "USB 3.0" mode and not give you a message to use a USB 3.0 cable?
I have my old 1Ah car charger and when I use a USB 2.0 cable, the phone says to use the USB 3.0 cable for faster charging.
But, looking at this pinout:

It seems like only the USB 2.0 section is providing the power?
It's utterly confusing. Would be nice if someone who really knows this stuff explain how it works?

What's strange is that I have a car charger that is 1.0Ah. When I use a USB 2.0 cable, the phone tells me to use a USB 3.0 cable for faster charging.
When I use a USB 3.0 cable, the message does not appear.
But I'm thinking that the car charger can only put out 1.0Ah regardless of the cable that is used?
Hi everyone,
I have an old fast wireless charger pad from Samsung, it worked alright on my "old" Note 5 but it doesn't fast charge my new SG7 Edge (SM-G935W8).
The SG7 Edge does fast charge when connected on cable (yes, i turned fast charging option on) but it doesn't wireless fast charge. I tried using other, better cable but still no luck. It wireless charge at regular speed as it was using any regular Qi wireless charger pad.
Anyone have a clue how to fix it?
Thanks a lot.
Hi,
So I just got a new car charger: Xqisit 6Amp Micro USB xqisit.c om/index.p hp?productdetail=20425 (Add the http: and remove spaces as I cant post links yet)
My phone charges fine off the 1 amp port, but when connected to either the short built in cable, or using the same cable as with the 1amp port, my phone does not even detect it is connected to a charger
My phone is a Vodafone Galaxy S5, running the stock 4.4.2 firmware.
This charges fine using any other charger.
We have also tested my dads S5, which is running 5.0 which charges fine using any of the ports.
We've also tested both phones in a different car, and get exactly the same results.
Any ideas why my phone refuses to charge off the 2.4Amp ports on this charger?
