[Q] Problem with kernel / car charger or its meant to be? - Galaxy S Advance I9070 Q&A, Help & Troubleshooting

Hey,
So I went on a drive today, connected my phone to the car charger (Samsung cad300ube Galaxy S Advance charger) and drove away.
I had my phone connected to my BT headset, GPS was on with waze and off course mobile data was enabled (I'm connected to the charger, so why not ).
To my surprise, instead of seeing the battery go up, it went down!
I checked to see that it was connected and no cable problems (the phone said it was attached to charger and charging), but still the battery was draining. So I wanted to see maybe my charger was broken, so I closed Waze and continued my drive, this time the battery did charge, meaning with all the above options enabled the phone was still discharging even though connected to the charger.
So now the question is, why?
I checked the charger specs (output: 5V DC, 700 mA).
So my guess is 2 things, either my charger isn't giving this output (any way to check this from the phone?), or there is some bug in the kernel when so many modules are draining the battery (I am using Cocore E4.0).
Any advice?

Car chargers bricking Kaisers

What exactly is the scoop on this? Is it that they overpower the charging circuit (everyone says they charge the phones faster)? Is there a way to tell you're about to do damage?
I don't use the car charger that came with my Kaiser, I have several generic chargers which all work just fine. However I noticed that when running GPS, although the charge light was on, the battery wouldn't really charge. It wouldn't discharge either, I put it up to the extra drain on the phone's power system.
The other day though, my phone... stopped charging? I was driving (GPS) and the phone suddenly beeped a critical battery warning, the charge light was off... but the power was plugged in and the charger's power light in the cigarette socket was on. It WAS making a connection to the phone: if I unplugged it the screen would go dimmer, if I plugged it back in it would get brighter. But it still seemed to be running off the battery, which was draining regardless. The moment I got to my destination, it all powered off. Is this a forewarning of darker circumstances to come?
from what I've read you should not be using generic chargers. The amperage could differ. Therefore, if the electricity in your vehicle spikes you could be riding with a paper weight.
In addition, it is common that your device will not charge (nor discharge) while running your gps application. I play monopoly often while my phone is in the charger and my device usually doesn't charge while I am playing.
Also, I think the pinout on generic USB chargers are different. The ones that are for Moto Razr / Blackberry phones dont work to charge the phones ( as I have a work blackberry and tried it) It didnt hurt my phone, however it just didnt charge. I have heard of others damaging but if its not made for the kaiser, I wouldn't try it.
I've never had access to Moto Razr / Blackberry chargers. While I can't speak for those, I know generic USB chargers would have exactly the same pinout as the stock Kaiser charger. The amperage supplied may indeed differ, I think that might have explained my issue above. It was almost like the charge circuit 'gave up' since the phone was demanding as much/more power as it was getting.

My razr charger works perfect with my tilt.. (MOTOROLLA branded - not generic)
Ditto on the motorola razr charger;Have an old razr charger I use it for travelling instead of unplugging my original;works fine!!
+2 on the Motorola branded car charger...charges my Tilt just fine. Now I'm paranoid, though...

That is the exact same thing I am experiencing with my Tilt.
Tilt is charging from a generic car-to-USB and USB cable.
I start TomTom.
Charging works fine for a while.
Then suddenly the charging stops and the battery is drained.
I found only two ways to get it to charge again:
1. Turn off device with TomTom charging; hold Tilt against cool air flowing from AC; plug into charger (while still off) ... then the phone turns on and charges.
2. Take out the battery; put it back in ... start phone.
It does seem that either the phone can draw power faster than a USB charger can supply it or the use of wifi and gps whilst charging overheats it. I particularly see this behavior when I'm running tomtom and navizon. The phone seems to remain charging longer in cooler weather or if I point an air vent at it. My current no wifi woes started after an occurrence of just this behaviour the other day.
RAZR chargers don't have enough current and it doesn't keep a positive charge when using the GPS. It says it's charging but ultimately it goes down. Sometimes it stops charging and I had to unplug it and plug it back in. Use a charger made for the Kaiser. The charger from my brother's bluetooth GPS works fine though.
I have a generic USB cigar lighter adapter which I have been using to power mine with no problem. The only way I can see a charger frying a phone is if there is a voltage spike that isn't regulated.
The charger needs to be rated with an output of 5v 2amps which is what the electric charger is rated at. Bought one off ebay for $6. Most car chargers are rated quite a bit lower (400ma).
As the previous post states, some chargers are rated at under 500ma. This is not enough to change the Kaiser... I find that the Blackberry charger works fine, but sometimes takes a very long time to charge as the current isn't quite enough. I have a generic one at about 1000ma and that works fine.
USB from a PC is normally 500ma sustained.
I think there's another thread or 2 about this somewhere. I've been having the same problem with the Kaiser not charging via generic and razr car chargers.
After seeing the other thread I bought an HTC charger from ebay - at least it looks like one and is advertised as one! The sticker on the 'real' HTC charger only says 0.5 amp (same as the others are rated), but charges no problem with TomTom going.
I tried measuring the current using different chargers and PowerGuard and I think there is a definite difference (although not an easy thing to interpret). I notice the cable is significantly heavier on the real HTC charger (also coiled and tends to drag the phone from where I mount it a little). Others have said the pinouts are different too.
I looked for a 2amp charger but couldn't find one (if anyone knows a source?).
It's an intriguing problem but a 'real' HTC charger seems to fix it.
The other thread: http://forum.xda-developers.com/showthread.php?t=406771
There were a range of brodit car mounts with built-in chargers that bricked the kaiser. I bought one and it instantly blew it's fuse. I replace the fuse and it blew my kaiser up instead.
Assuming it was the kaiser I had it replaced, only for the charger to blow it up again.
Since then I contacted dsldevelopments (UK Distributor) who replaced it with an updated model. I have not had any issues after that.
I had this problem (Kaiser not charging in the car when GPS is on) and resolved it totally by getting the offical HTC car charger. Although output is 0.5A it is rated to 2A - my previous generic car charger was only rated to one amp and that would work fine as long I wasn't using GPS but once I ran GPS it just couldn't cope. Definately resolved this problem with the official HTC car charger (got mine of flea bay for £8)

I've had no problem with designed-for-Moto chargers and ones specifically designed to charge over USB from a dumb charger.
The problem is that drawing more than 100 mA without negotiating a connection with a PC violates the USB specification. Many manufacturers have gotten around this by finding other ways to signal the presence of a "dumb" charger, telling the phone it can draw more than 100 mA.
In the case of Mini-USB devices like the Motos, Blackberries, and HTC devices, the Mini-USB connector has a fifth pin that is normally not connected. If the charger plug grounds this pin, it signals to the device that it is permitted to draw more than 100 mA without a PC connection.
If you get a charger that does not ground this pin, an HTC device will not charge rapidly, if at all. (Typically only charges slowly when screen is off). This is why you get two cables when you order a single MiniSync from BoxWave, for example. They give you one "Sync and charge from PC" cable (no pin grounded) and one "Charge only" cable (pin grounded for dumb chargers). (If the pin is grounded it interferes with data communications for most devices.)
I use a motorola charger, which is fine if you do not use GPS.
when I use the GPS after some time the battery is very hot and stops load, but if I put the cell in front of the AC, just cools again to load.
I think the problem is due to protection from overheating battery
Belkin Charger
I grabbed a Belkin charger for my KRAZR/RAZR phones and it seems to work just fine, even with GPS running. My official Moto one also works fine with the tilt in GPS mode.
I do notice, though, that no matter what I'm using to charge it with, with GPS it gets hot. Since Li-Ion batteries are supposed to stop charging at a certain temp, it's possible that the combination of a lower grade charger and the heat generated by using GPS/WiFi/Cell at the same time (or any combo of the three), might be the issue.

Help! charging question....

does anyone know of any tweak, app or utility that will disable the semi-regular notification telling me that "the usb port I am using does not have sufficient current to charge the device, please close some applications." It comes on whenever I am playing music and then switch over to my gps app. I'm never really in the car long enough and I think the normal warning when the battery gets low is sufficient enough without this thing popping up ever time i open a new app.
Any help is very appreciated. Its an ATT Pure with the last feb 16th energy rom, maxmanila, and sense 2.5
Thanks!
This warning message is to alert you to the fact that you are discharging the battery at a greater rate than you are charging.
It is not to tell you the battery is low although that is what would eventually happen rather more quickly than normal.
In effect the charge circuit is being overloaded and the battery capacity is being drawn down and depending on the usage, will result in increased heat generation which is bad for the circuits and the battery cell.
I gather you are using the device in the car. You should have a USB adapter that gives 1000mAh, at least, and if it's not then the associated circuits and also the wiring, could well be showing signs of damage from heat build up.
If the USB adapter is rated at anything less than 1000mAh I would suggest obtaining a more suitable one because it's not up to the job.
As for disabling the notification it will be a registry tweak if it's possible at all.
thanks for the help.
i checked the car charger,it is rated correctly. this also happens when its plugged into the pc usb port, or a powered hub. the only time it doesnt happen is when its connected to the htc ac adapter. when i am using it in the car, it still charges to full ( albeit slower than normal) even with the tom tom ap, music player, palringo, and bing open. I was aware that the battery will drain, i just want the only warning to be the low battery warning, which i have set to 20 percent, but even in the car, it doesnt ever get that low ( i do periodically discharge it to empty for battery maintenance reasons)

If you have a car charger rated at 1000mAh and it is exhibiting what you say then there is something wrong with it!
USB ports are rated at 500mAh nominal. That is to say the manufacturer of the equipment should make sure that one port will give that output.
It sometimes doesn't work that way and you get badly designed port power feeds across however many ports that you have and if you have more than one in use then the current drops of accordingly. Then it struggles to charge your phone.
Even powered hubs can suffer this way.
When you use a wall charger that all changes and the whole thing works efficiently.
Having your phone under stress like this in your car is not a good thing and neither is periodic discharge. It's just not necessary.
Could you please give me an advice? I'm using my tom-tom charger for my td2 in the car. It says 2A for output while the td2 original wall charger says 1A. Do you reckon is there any problem? many thanks.
If the car charger at 2Ah does not have a "shut down" circuit, or the charging system in the phone does not, then you will, in short order, smoke the battery.
Ok, txs jdwilson. You mean "shut down" circuit as a way the charger prevents the energy pass to the phone when the baterry if full but allows it when more energy is needed? By the way, now i've notice that my tom-tom says input 1A! So, the charger as the "shut down" circuit or tom-tom as in it, or i will have the same problem on my tom-tom, although the charger is the tom-tom original one. Thanks

Cannot charge with wall outlet

Recently my X1 cannot be charged with USB cable through wall outlet & even car charger , but able to charge with USB cable through PC.
Anyone do encounter the same problem?
Well that's a strange one - how long was it connected to the wall?
Without getting into the discussion about volts and amps provided, and amps drawn by the phone, any method should charge.
In terms of speed, I would think the wall would charge fastest (see above), and the USB slowest.
Did the phone show on the top bar, the charging icon when attached to the wall? Or after a period of time there was no increment in the % charge showing??
If the battery was down to 0%, you probably wouldn't see an immediate increase in the % charge. The % charge is orientative, especially at both ends of the scale.

I do agree with you. Charging with wall outlet is faster. Therefore, normally I'm charging my X1 with wall outlet, unless in office, will use PC USB.
Top bar never show charging icon, but once I charge it with PC USB, the charging icon show up immediately.
It seems like no power for the USB when connected to the wall outlet. I've tested with battery removed, plugged in USB cable connected to wall outlet, there is no charging illumination light. I cannot power on it.
I tried to recall, it happened after I used a USB charger for my MP3 player. The next day, when I tried to charge with car charger. To my surprise, the USB connection notification showed up (I do remember, while charging with wall outlet or car charger, it will never prompt me for USB connection).
I don't think, it is the ROM issue. Try a few ROM still having the same problem.
From now, I got to live with PC USB :|
X1 Charging problem
I have same problem. I can not charge via both USB-PC and Wall. In order to charge the phone, I have to switch it off and then charge it.
This happened after I used CHEAP car charger from dealexteme.com
Now everytime I want to charge my phone, I have to switch it off.

let's me try with power off charging with wall outlet
well thats why se said USE only original accessories...you need to change the power ic on the board.

make sure your charger have an out put minimum is 1.Ah ,if lest than that it will not work , that is the troublem

I'm using the original SE charger!? I would not think the problem with the charger, but my X1 was screwed by the incompatible MP3 USB charger
Yep same with me, not sure why mine started doing that though, I never got used a cheap charger. Maybe its the rom... I am trying a new one now.

it's not caused by the ROM, I'm very sure. I've installed different ROM. The problem still exist.
I am having a similar problem. When the phone completely discharges , i am unable to charge it with any power adapter or even car charger. I have to initially charge the phone using a PC , then after the power is around 15% , then the phone gets charged with a normal adapter.. any suggestions??
same problem. It happends when the battery is completely discharged.
what I do is use a charger w/ low amp rating (.1) and plug it in for at least 10-20min. Give it some time, it will start charging after a while (indicated by the blinking lights). After that, you can turn it on and charge it normally
I had a similar problem twice.Both times I solved it by replacing the charger.
the same happen to me and i have another issue
my xperia doesnt work as usb mass storage!!!
the solution was buying another charger but..the usb mass storage issue still not working as a flash drive!!

I guess something goes wrong with battery controller

[Q] Charging problem

Hi,
I have a new and flawless Note, the USB connector is OK.
At night I connect the Note to the charger and I put some music on to fall asleep. Playback is configured to just play one album once.
Normally I put the phone in Flight Mode, in order to sleep without unnecessary radiation next to me.
On some few occations (it happend to me for like 5 times now), in the morning, the phone is not charged at all! But I am 100% sure that the battery status icon on the top bar signaled the charging mode.
This morning it happend again and I noticed that I left the Flight Mode off (because my wife is away and I want to stay in contact if needed).
Also, I noticed that I have been using a ZTE charger specked with 750mA, while the original Samsung Galaxy Note charger is rated 1000mA.
Can it be, that I was using the ZTE charger on its limit and that having apps running, or maintaining flight mode off, was enough to actually not being able to deliver that extra juice to charge the battery?
The other reason could perhaps be a software problem, like some app draining the battery as much as the charger is able to charge, so in the end the battery stays more or less the same.
I am positive that the USB port is not broken. I.E. I tested by unplugging and plugging the charger from the wall socket instead from the phone and all is recognized OK. Also, no issues when connecting to the PC.
What is odd: on previous occations I think I remember that I just plugged the phone back and it charged.
I swapped the chargers, but still I have this odd impression, fearing that the device might have an issue.
Anyone had similar problems?
Cheers,
vma
Yes, looks like a weak USB charge problem. You get similar behaviour if you try to charge the device from a PC - sometimes I have mine plugged in to my PC at work all day and it barely charges. Get home, put the official charger from Samsung in from a walk socket and it charges in an hour or two max.

car charger for GPS / Maps

I didn't see this in any other posts, so I thought I'd ask.
I have a aftermaket car charger that does not show "slow charging" but when I am using google maps, it will slowly drain the battery, but if I use a power inverter and use the ac adaptor and cable that came with the phone, it charges faster than the screen, gps, and maps can use it up.
does anyone know of a car charger that is up to this challange?

Because most likely it is a 800ma-1amp charger. Get a 2 or more amp charger... very extensive car charger thread here....
My father bought one of these for his G2:
http://www.amazon.com/Vehicle-Charger-Dual-Output-Universal/dp/B00C9D5EJI
I'm not sure where he ordered it from.
I tried it out on my G2 with Waze running, screen on, and GPS running. No slow charge indicator. I left work with the battery at 69%, drove for a little over 20 minutes, and ended up at 81%. That's a nice fast charge with all of that running. I'll try it sometime with bluetooth and pandora on as well, but I imagine it'll keep up.
I purchased one of these.

Make sure you have a micro usb cable that can handle it as well. My old cable had the "slow charging" notification but once I switched it out for the one that came with the phone, it went away.
hope that helps.
I just buy a car charger for iPad and it works perfectly with 2.1A max. Screen on 100% light, battery turn 60% to 80% on 40min.
