Ok. Ever since rooting my GN2 3 days ago, my phone has been having charging issues. I am running MacksROM 2.5 with the latest Perseus kernel. I have a Samsung 5v - 2a charger and the charger is SUPER SLOW...like 1% every 30 minutes! I tried a full wipe(3x) and re-installed the ROM & kernel. I hear that the USB ports on these things were fragile as well. Is this a kernel issue?
I just got a t-mobile version of the S4 and I'm loving it, but I noticed it is very very slow to charge.
Aside from light to medium usage i didn't touch it much between last night and today. I had it plugged in and charging via USB, but it maybe charged about 40-45% in 6+ hours. My old phone (LG G2X) never took this long to charge.
More Info;
This was using the Stock T-mobile Rom
I have since rooted and installed CM10 nightly on the phone, It appears to suffer the same issue
Between 9:27 to 10:00 it went from 67% to %74, My LG went from %39 -%56 in about 20 minutes. By those quick number it will take 7 hours to charge the S4 while only 3 to fully charge the g2x
Is this normal? is there anything i can do to fix/test or alleviate this?

The question for you is the source? If you plugged it into your compy, it will take forever as standard compy USB ports (USB 2.0) provide only about 500 mA. The stock S4 charger is 2 Amps.
The fix, plug the phone into the wall using your stock charger. If it is still slow, it is probably your battery. Good luck.
Make sure to use the charger that it came with. Ever since I started using the stock charger my battery charges fast. Also it could be your plug so test it with another just in case.

Yup it was the charger, I have chargers pretty much where ever i go so i just used those. With the stock one it works great but i ran into another issue. I plugged it in and it was taking a really long time to charge with the stock charger, something like 3% in 30 minutes. I had to unplug and plug in the cable again and it charged normally.
Is this something I should worry about?
It could be possible that the cable was not properly seated in the phone, or the charger end was not properly seated in the wall cube. I wouldn't lose sleep over it unless it happens often. Could be a phone problem, but sounds like a one off to me.
Yea my lady like to use my charger with her HTC phone because it "charges faster". The S4 stock charger has the highest amp rating and provides juice at the highest rate to any device. :good:

There are a few factors here.....
1. The charger itself. The original Samsung is a 2A charger. If you use a different one (most are only 1A) it will take twice as long to charge.
2. The USB Cable. Believe it or not, not all cables are the same. With the standard charger and cable you will be able to charge @ 1900mA. Less then 2 hours to fully charge a completely dead battery. But.... plugging some USB cables into the standard charger will limit the charge down to just 600mA.... taking 3x_ longer to charge.
3. The other is the kernel. If you're using a newer custom kernel Samsung has limited to a max of 1200mA with the screen on & full 1900mA with the screen off.
Lastly, you can download an app on the playstore called Galaxy Charging Current. This will show you the charging rate should you want to test your setup.

This man speaks the truth. I use CurrentWidget and set to manual update. Whenever I'm testing cables/chargers, I plug in a known good cable (charges at 1900) to see what the charger is putting out. I do the same with a known good charger (2A - iPad and S4) and test the cables
I updated to 4.4.2 and flashed the Jedi rom. Everything works but I've noticed that my phone is charging incredibly slower. It looks like I'm charging at 450 mah, which I believe it should be at 1200? Someone mentioned red pill kernel but I don't think it'll work with the note 3.
Edit: I just unplugged the same charger and plugged it back in the same socket and it shot up to 1200...
A week ago my phone suddenly didn't charge and stuck on whatever battery percentage it was on and only charges when it's turned off.
I've tried replacing the battery with a new one and use another charger but the issue still the same. Until I've changed the ROM, it started to charge normally; So I reflashed the old ROM I was using (AICP Nougat 7.1) and installed ampere to see how much current is flowing during charging and it was between 875 and 1025mA then I enabled the option to see charing info on the lock screen and it was reading the following current as 1mA only and 0mA if I'm charging it from my laptop. (see the attachments below)
I've tried doing a clean flash of the ROM and flash a new kernel(Hybrid v9) and it still the same. no matter what charger or cable I use.
Any suggestions on how to fix this problem?
Thanks
In hybrid kernel try set 2000mA in boeffla-config app for AC currient charge section and turn on `ignore unstable power` and `ignore safety margin`.
It works for me.
hello i am with custom rom i already try all the aosp roms like crdroid ancient os and evoultion x and the fast charging is not work as well in stock rom from 0% to 100% it takes 40 minutes and in this rom it takes 40 minutes from 10% to 80% help
just curious since you already come from stock rom and you said fast charging still does not work does poco doesn't have indicator that it currently charging your device with fast charging technology like charging animation or some sort? on OPPO if you use the charger that doesn't deliver 65watt the animation would be gone
also are you still using the stock charger and usb cable that come out of the box?
In Stock rom, the charging speed varies with relation to battery percentage and battery temperature
