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
Hello,
I purchased this ivolver quick charger from amazon from lg g4 2 weeks ago based on the reviews people have written over here and then i put it on charging but it seems like that my phone used to discharge more than charge. I used the ampere app and it went to as low as -1490 mA.
Attaching a screenshot also.
Could you guys help me on what needs to be done?
For some reason, i cannot attach the screenshot only :|
Try disconnect and reconnect again on the charging cable. G4 sometimes need to do this for it to work. If your QC Charger have the LED Indicator you can tell. And if its rooted, install the CTT Mod and your G4 will charge and run colder.
And Ampere its only gives ballpark figure. Uninstall it cos its tend to drain your battery.

Good morning =)
I have been having some issues with my LG G4... Some weeks ago my G4 started having some "issues". I have been reading a lot and can't find an answer. I know there are already a lot of threads on this, I'm sorry. It all started when I left my phone to charge overnight, and in 8 hours more or less it only charged 70%. This has been happening sometimes... Since then I have tried different kernels, different cables and chargers. Currently it is connected to a samsung charger 2A, and its charging 870 mA.
The thing is, sometimes it charges normally from the charger, other times it doesn't. From power banks the story is very different, it is not able to charge normally at all with any of my chargers. (Between 70 and 270 mA, even with screen off!)
I don't know if it is the thermal throttling, or why it started happening now.
I have an H815 EUR, currently with Genesys rom and Imperium kernel, and the thermal mod...
Thank you
What are your charging times? Mine is like 5 - 7 hours from 5% - 100% on rooted stock rom lollipop 30B with stock kernel & stayed the same on crdroid 3.4. I'm still using the original charger & cable. The cable seems fine since I also use it with my s6 fast charger to charge my s6. Any suggestions?
