charging problems

hello.
i have arhd 3.3, 12.41 radio.
i put my phone into wall socket last night at 23 30 and this morning at 5:30 phone was still charging at 73%. at 6 30 it was at 83%. then i switched it off and back on, pluged the charger in, and the led went green in like 2 minutes.
what's this? i have the phone for 3 days now. does it take that long to charge or is it a rom problem? i am using the original charger.

looks like a rom problem. Best way to know will be trying different roms.

dont know if it is a rom problem. i think is a radio problem.

install current widget and see what the input milli ampage is. This should give you an idea of if your having a charging issue. Also when you have charged to true 100% (Not when the LED goes green but when current widget says you are no longer receiving a current (0 Mah)) then reboot to recovery and wipe the battery statistics.
I can't see the radio giving you an issue on charging, unless it was using almost more juice than you are putting in. The only time I have ever seen that behaviour is when using a USB charging cable and navigation at the same time.
Hope this helps.

i am using the charger that came with the device that uses indeed an usb cable connected to it.

I meant a USB only (not original) charger. As the charger supplied is actually a wall charger and is rated to supply the device with more "juice" than a standard USB socket (i think are rated for 1mah charging??)
The scenario I am using is when you use a phone for navigating and have it plugged into a 12v socket in a car using a USB adapter which will only give the lowest permitted power rating.

so......i think i have a problem.
when i plug the phone into the wall socket it says charging(usb)
when i plug it in laptop usb using the cable the same charging(usb).
wasn't it supposed to say charging(ac)?

Not sure about that, but even so my DHD will charge from flat in less time than yours was plugged in, how warm / cold was the room you had the phone charging in? Possibly it's getting too hot whilst charging which would lead to the phone reducing the charge rate?

now it;s on charge from about 30 min. it's not even warm. the battery is reported to have 27*

You might be having a damaged battery try replacing it with a new one.

the phone is new.
could it be because of setcpu 230-1228?

Yes I think it's supposed to say charging AC. Try cleaning the usb connectors thoroughly.

Yeh being informed that it is chargng over USB when in the well is definitely wrong. I suggest trying to get another cable or something like a newer style blackberry charger.

Charging via USB on computer

My device charges very slowly if the display is off. If the display is on it does not charge at all.
I've installed the Samsung drivers from the website. Is anyone else able to charge their device via USB? I need to know if I should exchange mine.

I was able to charge my sgs2 yesterday at work through the usb port. It might be the phone, or maybe the usb port you are trying to use doesn't have enough juice to charge the phone? have you tried another usb port on the computer?

usb will always charge really slow compared to an wall outlet

Yes I have tried multiple ports, computers, and cables. Oh well, I guess I'll live with it.

USB supplies max 500mA. Is probably half what the wall charger is giving you. Nexus S is only 750. My guess gsII is 1000 (1A). iPad charger is 2A.
Edit: no a higher power one than the stock charger won't charge the phone faster in a noticeable way. Charging circuits in remotely modern phones limit current to that safe max. If they don't you're probably risking damaging your phone.

I understand that the USB on the computer is weaker. I was surprised to see that when the phone was connected to the computer, screen on, and streaming music that my battery was actually reducing slowly. I would expect the opposite and this behavior seems abnormal.
Sent from my SGH-T989 using XDA App

that's exactly the reason why in car i use the 2A charger (2000 mAh), and in house i use 1000 mAh wall charger
if i leave it at the computer USB charging, i've to keep it iddle for it to charge after like... 4+ hours
that's usually what i do at the work place, so i keep the battery topped up, for when i need to jump back in the road
as long as you have WiFi on, or 3G/4G on, or if the CPU is in high activity, you'll never see the charge ever reaching the battery.
i always keep a spare wall charger at the office as well for times when i need a quick charge

Thanks for the input everyone! I'm glad it's not defective cause I love this phone!

My issue is a little different but decided against another thread. My phone will not charge with any other cable. Has to be pluged in to oem cable. I left it all night on my old phones charger and woke up with it almost dead. Plugged into oem it just charges super slow. Should i take it back?

Does the other micro USB cable work with other devices? If not, might be a defective cable.
On a side note, who prefers to charge via 500mah vs 1A? I have been charging my phone since day one using my printer, as well as my old Iphone. My battery performance is great! +24 hours on a single charge with moderate browsing 50/50 wifi and 4g. I typically enable the "power save" feature with minimal brightness and 15 sec screen timeout.

[Q] Charging problem
I have an issue that has popped up today. When charging through PC, the phone (not battery) is getting pretty hot and losing charge. I'm not sure what could be causing it. I stopped all extra processes and turned off the screen. This is not occurring when the phone is off.

[Q] Very slow charging. why??

When i connect my galaxy note 2 to stock charger it shows that in my battery stats it's charging as USB not AC.
Well what's supposed to be the problem. is my charger broken or the usb port in my phone is damaged??

Are you using the stock charger with the stock USB cable? My note 2 was charging really slow until I realized that the USB extension cable I was using wasn't delivering enough juice.

Do you have another 2A charger/USB cable that you can test from? I use an HP Touchpad charger + cable because its 2A and has a long cable.

I just happen to experience the same thing. I have had my Note II for a couple of weeks now and it have always charged from almost empty to full in less than 2,5 hours. Today however, it's going really slow. I do not know why. I've tried everything I can think of. I juse only the stock charger. Also tried the Ipad charger - no luck. This seem to be a quite common problem.

Hmm, just as I thought, more and more of this should be coming in upcoming days. I lost two good night's sleep because of this. Anyway, this is what I have done and you guys SHOULD do.

first time ever i have faced this issue (slow charging) couple of days back. it was dropped to almost 1%/3min
I have simply reboot to recovery and wiped cache
Now it come back to normal 40%/hr.

Sv: [Q] Very slow charging. why??
I have discovered that the stock charging usb-cable only has 4 pins in the micro-usb end. It looks like on is missing, from the standard five-pins. Can anyone check your stock usbs and see if there are four or five pins, and report back? Thanks!

I've mentioned it on my topic, I'm sure you haven't read it. Look above.
Anyway, mine has 4 pins.

My cable got only 4 pins. The second from the right is missing if you have the USB logo up.

I found a huge variance in charging rates based on a combination of chargers and cables. Goes to show that the cable makes a huge difference. Here's my findings:
** Stock Charger (2A):
w/Stock Cable (4-pin) - 1698
w/Cable from another phone (5-pin) - 1698
w/Cable from battery pack (5-pin)- 1698
w/generic eBay cable (4-pin)- 100! - It didn't charge at all, even with screen off.
** iPhone Charger (1A):
w/Stock Cable (4-pin) - 1300
w/Cable from another phone (5-pin) - 1100
w/Cable from battery pack (5-pin) - 1300
w/generic eBay cable (4-pin) - 100!
** Car Charger (1A):
w/another generic eBay cable - 490

[Q] What is probably the cause of slow charging?

I was curious that my phone sometimes used more than 5-7 hours to make the battery fully charged. It occurs on both Adam and Perseus kernel, and on both pre-rooted and Wanam rom.
And of course, I charge my phone with the plug, not USB port.

I have the same issues once in a while. Try to download GCC (Galaxy Charging Current) from Play Store and check on your average current while charging. Then from there, you can see where the problem occur.

The charger input on the phone is the cause

I knew something was wrong when it took my phone 6 hours to charge from 22% to fully charged on the stock kernel, so I had my carrier swap my data cable. Swapping the data cable didn't fix the random slow charging issue. If you view the battery stats under settings, your phone will indicate what kind of source it's getting its charge from. I discovered sometimes when you plug your phone in via the stock travel AC adapter, your phone detects it as a USB port. It's not the charger that is the problem, but how Sammy designed the charger port or an error during the assembly process. I found a work around to avoid the phone thinking it's being plugged into a USB port. Once I initially lineup the data cable with the charger port, very very gently push down on the data cable as you fully insert it into the charger port. If you don't do so, it's usually a hit or miss when it comes down to what the phone will detect between AC and USB mode. This is the first phone that I own that seems to have this issue. Every since I've figured out what's been happening, I've been able without fail to avoid the slow charging issue.
Since discovering the quick fix to the slow charging with the Samsung data cable, I've discovered that my old HTC data cable works flawlessly without having to make any adjustments as I insert the cable into the charger port.

I tried using this app and it told me as the picture below.
What does it mean? Is it normal or abnormal?

What mode is your phone indicating that it's connected to. This can be viewed in the battery stats screen.

Slow Charging

When I plug in my power adapter to charge the tablet more often now I get the Slow Charging notification that says battery is charging slowly due to low electric current of TA/USB connection. Any one else seeing this? I am using the stock charger supplied with the tablet. I have tried this on several AC outlets in several different locations. It does not seen to affect the ability to charge the tablet it just charges it a little slower.

Thanks for the reply. I am starting to think my power adapter is not putting out the correct current it should be. I will try using a different 2A charger and see how it goes.

You might also try a different cord!

You may try to install "battery monitor widget", it will tell you charging in USB mode or AC mode.
I also find the stock LG charger slow charging, the widget shows I'm only charging at around 1100mA max. While the charger itself label said Output 1.8A max. I can't reach this level yet.
If I charge with a stock nexus 7 charger (which is 2A rated), it'll get worse...just reach around 800mA max.
I'm still not sure what's wrong with the charger or the tablet itself...

I can say that the cable that came with the gpad does charge faster than a thinner cable I had. Both were tested plugged into the stock LG charger.

When I pulled my g pad out of the box and saw the stock charger was below 2A I put it back in the box. I charge my tablet with the 2A charger that my note 2 uses.

I've seen this problem intermittently with the stock LG charger and today it seems to have become a permanent fault. Swapping to my Note 3 charger things are back to normal once more. Swapping back and forth repeatedly the LG charger triggers the warning and the Note charger is fine. It looks like the LG charger is a bit rubbish. I'll press for a warranty replacement.

I have noticed mine recharges really slowly as well. Using the stock charger, and the battery app previously mentioned, it gives me about 1.1A from the stock charger. Using my Vita charger rated at 1.5A I get about 1.4 into the G Pad. It seems their charger just stinks.
I sent them a support query to see if they will replace it without hassle, if they want me to send it back I'll just buy something else instead.
Edit: Heard back from LG, they want me to send the whole thing back to them or return it to Newegg. Not sure why they won't just ship me a replacement charger, it would be much cheaper for them in the long run.

Further investigation revealed the original cable to be at fault, as it would not make a data connection with either of my laptops. Another cable from my old Galaxy Note worked perfectly. Even so there is still a question mark about the charger as well. Today I spoke to an LG support rep who promised to send a new charger and cable. They should arrive within five working days. I had read of mixed opinions on LG's support, but so far it all seems encouraging.
