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

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'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.
Hey Everyone,
Thought I would start a car charger thread.
I picked up one of these at Walmart the other day:
http://store.griffintechnology.com/smartphone/powerjolt-dual-universal-micro
And it works quite wonderfully. It's tiny, and even with bluetooth/GPS/Navigation running, it was slowly charging the battery. And it charges it quite quick if you don't have nav running.
It can be a bit annoying to pull out once stuck in, although you probably don't need to do that very often.

Glad to hear though that it charges even while using GPS.
what is the exact output of each USB of this Griffen car charger ?
i have a JABRA charger (comes with JABRA Cruiser) and it doesnt seem to charge my GN while GPS navigation is on (even though its saying charging on the battery icon)
it used to work perfectly on my HTC Desire HD (with GPS+Bluetooth+WIFI ON )
any recommendation on how to fix this please ? like a reference output current that is enough to charge the GN while navigating ?
thanks.

The Griffen claims 1A per USB port, and I believe it.
Online reviews say some users with other phones need to mod the Griffen to charge their phone, otherwise it only supplies 100mA. Some crack open/mod the Griffen to short two terminals to get the full charging ability, and/or use a 'charging cable' which shorts the terminals within the cable.
As a reminder, the Griffen seems to charge the Note full blast, but perhaps something similar is needed for the Jabra. I suggest installing 'Currentwidget' to see what sort of charge you are getting.

Thank you for the reply.
I have battery monitor widget installed & it shows charging via usb when i connect it to jabra charger, but the weird thing is that the galaxy note starts mtp mode once i connect it!
Could it be the cable? Or shall i just take the griffin charger to solve this?
By the way,griffin charger works out of the box out do i have to solder modify it?

I just bought this dual port 2.1A + 1A charger on eBay for £2.49 inclusive and delivered the following day....
http://www.ebay.co.uk/itm/2-1A-Dual...neChargers&hash=item19ca66b4df#ht_2865wt_1163
At first it seemed the phone was only drawing a "USB" level of current, so I was all set to rip it apart and solder the centre pins to force AC charging, but when I double checked with a dry run and a temporary short the phone switched to AC charging. Now it seems to be continuing to draw "AC" levels, so maybe I had a poor contact initially and a few (un)plugging operations have made the contacts more reliable. I'll try it out later today with satnav running and see if it keeps up with the pace and report back.
EDIT : Charge level draining like water out of a sieve with this thing whilst running satnav, and the phone said it was "AC" charging too. Switching ports didn't help.
i'm using the official car charger from my old nexus, the only charger i found can charge my phone with 3g and nav on because of the 2A output. other cheap usb chargers i tried with so called 2A output just don't work

Because the charger I'm using is recognised as an USB charger, and therefore doesn't charge faster then 500mA.

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.

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.
I bought a Galaxy Tab S 10.5 when I was in Europe but now that I'm back home I can't use the charger cause they're different than what we use here. Do I have to buy a new one or is there any chance I can use my Galaxy S4's charger? I understand the chargers have some sort of voltage information I don't know if my phone's charger will work since the batteries are not the same. Thanks for your time.
Here's a picture with both chargers. Left is the Galaxy Tab S's. Right is my phone's. They appear to have the same values, I still ask because I noticed its taking a long time for the tab to charge.
http://i.imgur.com/rqxBFHH.jpg
Maybe not the exact answer your waiting for but anyhow.
There is a lot of talk about cables and chargers not working properly. So I installed Galaxy Charging Current (Play store) and checked all my chargers and cables.
First off all my cables worked fine, but thats not what your asking.
Install the app on your tab and check with what value its charging.
Then you know for sure if you can use the charger on the right. (Or buy a europe tot US adapter for your 5.3 volt charger)
(I charge my phone wit the tab charger and have no problem)
I bought this little usb amp/volt meter and checked all my chargers and cords. Maybe 10% of them were junk. Some actually put out 5.3 volts like the stock charger. They all put out different amps. Some below 1.
Hans,
I downloaded that app. I dont know what I'm looking for. Here is a screenshot. Can you tell me what the readings mean and if I'm within the norms? Thank you!

Here is another reading a few minutes later as it warmed up..
and lastly, ten minutes later, as the charger is now fully hot..
This app is useless. Its readings have nothing to do with real current from charger. I have PortaPow USB Power Monitor and it clearly shows that Tab S 10.5 takes 1.75A from oem charger and this app shows values between 1 and 1.2A.

I dont know if its useless but when T700 is connected to my pc it show 476 mA , connected to my original charger it shows 1800 mA and connected to my 1 amp phone charger it shows 745 mA.
The values that I expected.
From the makers site I learned only Maximum value is important.
Where the USB plugs into the tablet to charge. Is it suppose to get really warm?

It shows what your tablet should take from the charger not what it is actually taking. So if you connect it to 2A charger it will show 1.8A because that's maximum value Samsung designed Tab S to be charging at. I did lot o testing and this app will always show 1800mA maximum when tablet is actually taking much less current for example when connected with long cable (15ft). My testing shows that longest cable I can use is 10ft 28/24AWG from Monoprice and oem charger. 15ft cable is only charging at 1.2A and any cable longer than 3ft is unusable with Anker 40W IQ charger. OEM Samsung charger gives 5.45V not ~5V as any other USB charger.
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.
