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?

Sorry if this has been asked before or in the wrong place...
Anyways, when I was using CM7 RC4 I noticed that if I charged my phone by USB on my MacBook the battery life was significantly reduced compared to wall charge. Anyone elts notice this? Or is this just me?
I flashed CM7 Final earlier today, and while at work I read about the GPS fix so I am in the middle of flashing Fresh to do the fix but I am going right back to CM7 final!!
It shouldn't affect your battery life. USB charging will be slower than a wall charger such as the stock one, which supports 1 amp charging and is recognized as an "AC" charger. But once you reach 100%, your battery life shouldn't be affected by how you got there.
I noticed something really odd with charge times on the couple of roms I've been on since getting this phone.
Starting off, I got the phone and immediately flashed Carbon rom. I've noticed extremely poor charge times. This was using the stock AC adapter and usb cable. Surely it shouldn't take that long to charge. The night I noticed I had charging issues, I went to bed when the phone was @ 60% charge. Woke up 7 hours later, phone was at 80%. Ended up playing some games / using the phone and while plugged in charging, the battery was draining down.
The 2nd night. same thing happened. So I decided to watch the phone charge while doing nothing. It would literally climb 1% after 5-10 minutes at best. So further investigating, I was looking around on xda and there were quite a few threads about people having very slow charge times on the Note 2 and some that can fully charge from 0-100 in ~ 2-3 hours. I ended up installing battery monitoring widgets (Elixir Widgets to show charge mA values and Battery Monitor Pro. So apparently even though it shows my phone is receiving 1600-1800 mA, it still charges extremely slow.
The odd thing was, the rate it was charging off the wall was slower than plugging into my comp to charge (and when plugged into my comp, it showed it intaking 500-900 mA).
Now the really odd thing is, I decided to flash a different rom (LiquidSmooth) because of the annoying mdm_hsic_pm0 wake locks carbon was having. I used the phone to about 80% configuring it and I plugged it into the wall charger. Walked away for 5-10 min, and came back and saw it was at 85%. Before, 5% would have taken me a good 20 minutes of charging. After a while, I looked back at Battery Monitor Pro and according to the history, it charged from 80%-100% within 30 minutes. This charging issue is ridiculous. Fixed by swapping roms. Perhaps there are some coding issues somewhere affecting charge rates.
You should post this on the carbon wall and let them know what version u were using.

I have made a lot of comments in this thread regarding charging time issue. Most of the charging widget apps you find in the Playstore are useless. The only app that correctly display your REAL charging current is here: (look for the op's comments and mine, I have provided a lot analysis for everyone's benefit)

I noticed the same thing when I went from stock to tweaked 1.5
What fixed it for me was moving the charger from a strip directly to a wall plug. Kind of a pain since now I have to charge it in another room.

I had to switch roms to get it to charge normally. Now my phone charges about 1%/min. Before on Carbon, it was charging 1% every 7-10 min. I been using the stock 2A charger adapter + stock cable that came w/ the note 2 in the wall. Can't possibly be adapter issue as rom swap fixed it for me.

I don't have the issue and I use Carbon so it's not the ROM.
I installed the app mentioned in the thread and my charge voltage is normal.
Carbon Nightly | Kroz Hue Theme | Crack Flasher
When plugged in, my Note II will LOSE juice while I use it but will charge normally while the screen is off. This is the case even with the brightness set to auto or even manually set to it's lowest level while using an app with a black theme (like Reddit Is Fun). Checking out the battery usage still says the screen uses the most power. This happened while stock and with the Jedi 12 ROM.
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...
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?
