Galaxy note II charging slowly

Hello I don't know if I can find some help here but I'm currently running tweaked Rom on my GNII and have since then noticed that it charges very slow. I've got two different samsung chargers and they both do the same thing. While it's plugged in it seems to still lose juice. It charged for over 6 hrs and only made it to 45% has anyone encountered this issue?? Thank you.

You have tweaked voltage control of your rom. Which tweak tool you've used? Check if there any reset to default option available. If not, reflash rom with all three wipes. Everything will be fine then.

I haven't noticed any type of voltage control on the other tweaked Rom. Thing is i used my brothers charger at his house and it charged ridiculously fast. Even now I've had it plugged into the computer at school and it's been at 59% for last 4 hrs. I know it's not the same voltage but it just hasn't moved at all.

If you don't want to fresh flash a new rom, try with a new full set charger.

Try installing app call Galaxy Charging Current in the Playstore
It has free and paid apps .. just get the free app to test your charger current to your phone
Only pay attention to the value on Maximum .. You should be getting at least 1000mAH to 1800mAH ..
normally I would get 1200-1500 mAH .. You will be very lucky to get 1700-1800mAH
Samsung are well known for the bad usb cable data which often cause slow charging ..
Bad cable will only flow 500mAH too your phone and that pretty much like charging through PC which will take forever to full charging

Yap, that's why I've recommend a new fulls set charger. I am using the plug of GTab and the cable is a nokia one. I've also faced slow charge and I've left the samsung cable.

Sometimes just replacing the samsung usb cable data will fix the problem .. Most of the time the culprit is the usb cable data
Another best option is to use Blackberry usb cable data.. their cables are good and more durable somehow compare to samsung cable

You're most likely using the charging cable of another phone. Use the note ii cable that came with the box. I used my S2 cable and the voltage is only around 780. Thenote ii cable got to 1800, big different.

If avatar is touchwiz based then you can use Perseus kernel. If its AOSP based then you can't unfortunately..

Slow Charging

My phone takes 5 to 6 hours to fully charge. It started about 3 days ago. I've tried Odin back to stock. I've tried different ROMs. I have also tried changing chargers and even a different battery. What can this be. It sucks to have to wait so long for my phone to charge.

It started on liquid with stock kernel then I tried devil kernel and nothing. Then I went Jedi x then to carbon. And now I'm on slim ROM. I haven't changed kernels anymore because I'm getting great battery life on slim but the charging is still slow.

I remember you asked this question about the Perseus kernel also if your running slim 4.2 neak kernel v2.1 has a fast charge setting if on 4.2 download the neak kernel 2.1 and the uneak engine from the play store to utilize all the kernel has to offer

I had slow charging issues on Carbon, but it's been fine on any other rom I've used. I also use NEAK kernel now and no issues here. Rootbox actually works great with NEAK and no charging issues whatsoever. You should give that a try if you don't want to use touchwiz. www.rootbox.ca

What worked for me I just removed the battery and cleaned the contacts of the battery and phone I don't know it might work for u. Good luck.!

Thank you guys for your input. I've been using neak kernel and uneak engine and I wouldn't say my charging is like when I got the phone, but its definitely not taking 6 hours to charge. Its taking maybe 4 now.

They all the same t0lteatt or t0lte. Used both.

Try changing charging cable, the factory one is not good in quality. There's an app that show how many current is taking the n2 when charging. That will give you a glimpse to know what is the cause. Mine was the cable. Hope it helps!

Wife had the same trouble, new cord fixed it... then I had the same issue, new cord, fixed it again.
we went from charging for 6 hours and not hitting 100% (starting from about 50) to going from about 70% to 100% in about 1 hour and still (mildly) using the phone
Change your cord guys, the samsung one stops working so well after a while. also you can use "galaxy charging current" app from app store to see if you are getting good charge levels

Thanks but I stated it wasn't the cord. It charges my s3 perfectly and I've already tried different cords.

Weird battery problem

Ok so I am on frosty v8 rom 4.2.1 I am using saber kernel 45.3 I have tried recalibration of the battery but for some reason when I am charging my phone now it says its charging on the lockscreen but the phone is still dropping power. So I installed battery monitor pro and I have noticed that it says its discharging but while plugged in but the phone isnt running anything in the background.
Will upload some pictures
I think it might be the battery or the charging cable.

He uses saber kernel. And I am using it. But I dont think its rom related. Or kernel related.

It's a tricky scenario. ..
I posted my own observation below yours ...
I get drainage while charging at a low battery% especially while using phone at same time .. This shouldn't be it's like low battery charge% is overriding the charging capabilities.
A phone should gain % while charging regardless of how you consume power least I'd think.
I wanna test this discharge/ charge theory while my phones at 80-90%.

now its really weird the phone is ice cold like 25degree, and the battery monitor pro app says the phone is charging not discharging but it says 0.0%/hr and the percentage is not moving up.. very confused.

I really dont think its rom related. Because I have been using the same rom for the last 10 months.

Paranoid Android battery and ram problem

Hello there,
So I upgraded my GT-N7100 from cm10.2 nightly to paranoid Android 3.6.
I had an amazing battery life with the cm but once I switched, 25 percent of the battery is only enough for a single hour, that's 4 hours from 100-0.
I also noticed that my free ram has been decreased by 150 mb (with cm=1.300 / with PA=1.150/1.200 gb)
I am afraid to debloat on my own because I might remove a necessary item that would ruin my whole rom.
PS: I searched for a good 30 mins about the battery problem and haven't found the perfect solution for a newbie like me.
P.PS: I have unlimited 3g which is running 24/7, but I had great battery life with the cm.
With Regards,
OverDub

Seems that there is no answer, I restored back to cm 10.2 because the charge was going faster than a v12 challenger.

Did u change your charging current or anything? That may be causing the problem. Also, once switching to a ROM, don't touch it and it'll charge faster. Happened to me too.
Smack that Thanks button if I helped!

I had this problem too when I was on a custom TW based rom on 4.2.1. The OS was recognizing the charge current as USB instead of AC. Tried changing the cables etc. Had no affect. Had to let the developer know about this.
Also keep in mind THIS exact same problem happens with the stock samsung cable as well. I had to use my Milo portable chargers cable to cure this issue.

Charging on cruise ship

Just passing along my experience on my cruise this week. I was running tweaked with faux kernal and everything was great. Charging at the hotel/airport was fine. I plug my phone in the first night on the ship and nothing is happening. I tried my wife's charger same result. Every plug in the room same result. My wife's s3 charged on both chargers fine. I eventually restored a nandroid of omni rom with Agni kernal. Still no charging. In the Agni settings there is a setting to dismiss unstable power. As soon as I checked that I had no problem charging my n2. I hope this helps someone else if they have a similar experience.

That is there because the battery needs to charge in a specific way or there are dangers involved. I doubt samsung's battery would blow but if you're using a third party then I would advise against this.
