Does it charge on the wall okay? I would try a different kernel out, see if that remedies it. If not, I would be suspicious of a damaged/faulty USB cable(they do/can go bad), or a faulty battery. Have you tried clearing your battery stats yet? I would do that, as well.

I'm guessing battery too, sprint should have a machine to check it by the way...

It's happened to me a few times. Sometimes the cable wiggles or something I guess.
I just unplug and replug and its fine.

I've had this happen consistently over the past few weeks, only with my car dock though. It charges fine both in my dock at work and on the standard charger at home. I'm using a Seidio dock, and I've done multiple things to find the issue. Both my wife and I have EVO 4g's with Seidio car docks. I swapped my dock for hers, no change. I swapped out the charging cable, no change. I used a different charger, no change. I tried my normal setup on my wife's phone, no change.
I don't know what else to do to figure the issue out. I have ordered a new charger that supplies 2.1A, as I've read that a low charger output could be the issue.
I am confused, as this combination has worked fine for about 8 months now. Why all of a sudden is it no longer charging properly? The battery could be the issue, as I know that the chemistry changes over time, but I'd like to know for certain before swapping out the battery.
I'd love to hear from others who are having the same issue.

Seidio Dock issue?
I've seen a few other posts with the same problem. Particularly this one: Post #1175
http://forum.xda-developers.com/showpost.php?p=16499063&postcount=1175
The one thing that is similar is that he is using the same car dock as I am, the Seidio dock.
I've been playing with this a bit, and have managed to isolate it to the Kernel. I flashed back to MikFroyo and the problem disappeared. It charged perfectly fine.
In Gingerbread (MikG 2.42), with both the stock Kernel and the Freedom Kernel, the phone won't charge properly in the dock. I've been keeping an eye on it with Battery Monitor Widget. Here are the results:

While I am driving, the kernel is showing a 100% full battery, however, it is discharging instead of going into the float mode. As soon as the phone is removed from the dock, it goes from 100% down to 80%. When I put it onto a desk charger, it charges fine with a normal float charge. If I remove the cord from the Seidio dock and plug it into the phone (with a mini -> micro USB adapter), it will charge normally and go into float mode.
Something was changed in the GB Kernel update that affected this behavior. Unfortunately, I'm not a programmer to get that deep to find out where the problem is.
Is there any help possible from anyone???

This always happens to me on AOSP roms. If you happen to be on an AOSP rom, just plug the charger back in then take it out.

I've tried that previously with no luck. I'm using a Sense ROM, currently MikG 2.42, but I had the same issue with the stock GB ROM.
Thanks for the suggestion.

Battery Charging Rate

Hi, I just had my SGSII for couple of days and noticed inconsistent battery charging rate which I've ruled out that is not charger/cable dependent. So I would like to ask if anyone have similar issue or could offer an explanation.
Basically I use the phone charges sometimes at 20%/hour, and sometimes at 40%/hour. I've been using both the samsung stock charger & iphone's 2A charger and there is no correlation between the charging rate & the charger I use. I use debloated Samsung ROM and the faux kernel.
The only other explanation that it could be is that when I get 40% charging rate, I was using 7b4(I think, not entirely sure), at 20%/hour, i was using stock, faux 7r2 or 9r.
below are the screen shot, among 5 times I've charged the phone #2 & #3 were at 40%/hour, the rests were at 20%/hour:

The device will charge the fastest when it is turned off. If you are streaming music, tethering and running other applications, it will obviously charge slower.

My phone has always been on idle when it's being charged so far. what's your charging rate?

Depends on what the phone is doing. If its idle and there are a lot of background processes going on, the rate is slower.

I believe it has to do with chargers in my case.
Since October I've used only two chargers the Samsung one that comes with the phone and my Kindle 1 charger.
Samsung: 40-50%
Kindle: 10-20%
90% of the time the phone is idling.

alright, i charged the phone again using the the stock charger, and it was about 40%/hour on standby mode. Weird I thought I tested it using the OEM charger and it was also 20%/hour. guess I remember it wrong...

ahh.. .here finally found the original topic http://forum.xda-developers.com/showthread.php?t=1332522&highlight=charging
there was a lot of good info on that one, as well as some unexplained behaviour, the same you are trying to figure out
all i know is that yes 2A charger does work, regardless of what the tester shows
and the Battery Widget App, i use it too, and i have to agree it's not very accurate, as it will only show you the actual rater after 2 minutes of charging it
however it's very close to the real values, specially when it's charging and the current flow, i get readings that matches the input quality of the charger, as in USB, Wall, 1 Amp, 2 Amp, 0.7 Amp, 0.45 Amp and so on

there is also the possibility of risking to be stuck at 100% when not using them OEM charger. I have couple of 3rd party charger lying around, so I'm going to try them one by one and see which one works. At least now i know that the apple charger does not work well with the phone(at least the older one, stuck at 100% after charged, and slow charging rate despite it's rated at 1.5Ah+, going to try my newer ipad2 charger).

as for the 100% stuck, as some other have pointed out it only happens when you use AC chargers of any kind
charging via USB doesn't cause the problem
using the original Samsung AC to USB charger also does not cause the problem simply because it's still using USB charging
i had another original OEM Samsung charger that i plugged in and it was also causing the 100% stuck issue, so it's just some sort of confirmation the phone seems to be expecting from a USB power/data cord but is not found on an AC power cord

Do you have to use the white charger that comes with it or can I use my old desire hd black rounded one. I'm just thinkng that the voltage or ampage or whatever it is may be different. Looking to keep a charger in the office you see. Also does it make a difference in terms of battery life and general goodness for the phone if you charge connected to your pc. Much obliged

No you'll be fine with both. Both will state their outputs on them, and both will be 5VDC at 1A. Generally any charger with a micro usb plug on the end will be charging at 5v. Charging current capacities vary. My wife's blackberry charger also works, but only has 600mA output current so charging the phone could take 40% longer. I've been using my desire charger on my onex.
The main reason to keep with HTC chargers, is that the cheap ebay Hong Kong stuff generally have cheap AC/DC converters in them, and are poorly regulated. This can cause a number if problems witha smart phone, such as heating and damaging the battery, and touch screen interference.
Charging froma PC USB output limits the charging to 500mA, so obviously will take twice as long as your HTC wall charger to get a full charge.

I've been using the charger for my HTC Desire with my One X since I got it - simply because it was already plugged in I've had no problems with charging.

Well, I am in the situation now that somehow the One X will not accept the Motorola Atrix (US) charger (I am in Singapore, but chargers "convert" automatically in my experience). It works fine though when plugged into the PC, but obviously will take a very long time to charge that way.
*edit*
It worked with the Moto charger once the battery charge was up to about 20%. When it was 2%, phone would only accept USB (or, potentially, the original HTC charger which I did not have at that moment).

Car charger that's recognised as an AC charger

Has anybody already found a charger for in the car, which is recognised by the phone as an AC charger? (besides from the official HTC car dock/charger)
Because the charger I'm using is recognised as an USB charger, and therefore doesn't charge faster then 500mA.

What chargers are you using?
And it's not a big problem, it's not even a problem, it's just how the charger/phone works..

having it recognize that it is AC vs USB is one problem... but even if it says it is charging via AC, it doesn't always pull more than 500ma (even if it is a 2.1a charger, etc). i've been testing chargers and inverters w/ac adapters all week. i've got one more to test before i narrow down the issue (hopefully).

this was just delivered: http://www.amazon.com/gp/product/B009TBF7IG/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
tested it using my normal method-- watching Battery Monitor Widget for about 20 minutes, while running Ingress. the app reported battery draw fluxuated between -56 and +300. i've been using Ingress as my test app because it tends to really hammer my battery. this new charger doesn't seem to be as consistent as the 5Vdc/2A wall charger i use with an inverter, but i'm going to keep trying it to see how it works in 'real world' cases over about an hour or two. i'll let you know, but this charger is potentially an answer to this car charger issue.

Ok that looks promising indeed. Does the phone recognise it as an ac charger?
Too bad I can't order from amazon.com and on amazon.co.uk it's not offered.

Yes, it is recognized as AC-- but so are most of the car adapters I've tried (mostly, those just have the 2 middle pins on the USB port shorted), but they have a lower wattage output, typically at like 6-8W. I bought this one specifically because it says it can output 5Vdc/2A, or 10W, per USB port. I suspect it will dip below 10W when both ports try to output at max capacity, but I'll be able to test that this weekend (and aside from testing, there's virtually no time where I'd have a need of that).
I performed a second test, about 30 minutes of talking on my phone via a bluetooth headset, Ingress open and running, push emails for GMail and Exchange, full brightness and volume, etc, and it only dropped down to discharging a handful of times. This is definitely much closer to the results I've gotten when testing a 5Vdc/2A output DC adapter.
You might be able to find other 5Vdc/2A adapters on Amazon UK, and ruling out the 'piece of junk' factor, hopefully some of them will work. I'd think that for the duds, you can at least return them for a refund by stating they don't output the proper wattage as stated on their product pages.

My LG G3 is Charging at almost 20Amps. Good or Bad?

I just got the LG G3 a few days ago and its charging at a rate of over 18+ amps! (Over 18000+ mA). My phone was on 35% about 10 min ago. Now it is at 63%. This is the first time i checked the charge current for this phone. My previous phone was a galaxy s3 and it averaged a charge current of 0.8-1.1 amps. I am not sure if this is a good or bad thing. My phones temp doesnt seem hot, also its charging incredibly fast. If anyone has had this happen please reply. I know this is not normal. I took a screenshot of the charge monitor. The app i used. To test the currents was "Battery Monitor Widget". In the picture you will see a red circle with a arrow pointed to it. That is the time when i took the charger off and replaced it with my other adapter but kept using the same cable.

That is wicked, though it had me scared! I tested wireless charging (I bought an insert for the back from AliExpress.com to make it Qi compatible) and also tested from the power adapter given to me with the phone. Below the yellow line is wireless charging and above is with the stock power cable. Notice that they are 0.5mAh different, but the mV is the same, so they charge about the same. Interesting! I'll have to test this further.
Cheers for posting this!

This could be why I burnt through a series of chargers a few weeks ago.....

Ok so I am now using the standard charger that i get up to 1800mA with. I gotta say though my charger that i modified charged my phone lightning fast with no heating issues as well or damaging of the battery. Unfortunately the modified charger can only be used with the newer phones. I had it tested with the galaxy s4, galaxy s5, and the htc one m8. But the only newer phone that didnt work with was the one plus one. The LG G3 definitely had the highest amp charge out of all of the phones. I will be doing more tests soon. But just to be safe i will be using my normal charger while i am away from the phone or when im sleeping. Here is the screenshot of the current charge with the stock charger.

Highly doubt that app is reporting accurately.

Omg can believe you guys are missing the mA flow ... +5197mA (+199.88%) per hour
These aren't output from your power adapter, it's a tally of how many mA have been recorded. Also from looking at your notification bar you have two blue tooth devices one of which isn't fully charged. There's a good chance this app doesn't account for that.

If you are using the standard charger, you can get 9 watts from it. No more. Given the voltage of the battery of 4v, there's little reason to think you could really be charging more than about 2200mA actual current into device, probably less due losses. For the the a 3000mAh battery, this means about 75 minutes to charge. I think the app is reporting something else or we are miss interpreting the data.
