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
Simple widget that shows power draw from a charger in mA. There is an update button on the widget, you can set auto refresh intervals and record logs.
- download zip in third post
- extract APK to SD root
- install
- apply widget.
Thanks to rm9, pgwipeout and Orel Bob, for creating the orginal Nexus one version. link
Thanks to ytj87 for finding the file to read and TDO for show the Nexus Version of the Widget link.
Last but by no means least, thanks to grennis for moding the app to work with the vibrant.
(see next post)
Here ya go... the file is attached.. enjoy!
I think you will need to first uninstall the current one, if you have it. I could not sign the apk with the same key the author used since he did not make it available (rightly so)
I think there is actually a bug in the APK, it should be handling this situation, but it's using a slightly wrong filename. I contacted the author already.
Grennis. thanks will change title of thread from think tank.
Works for me. Thanks. Please note that for the Vibrant it looks like the current displayed in the file is 2x the actual. Few data points to support it right now, but it makes sense (e.g. USB number ~800 in file, measured around 400mA).
See here - http://forum.xda-developers.com/showpost.php?p=8009138&postcount=73
Showing 854mA from my PC. 1022mA from the wall & 1050mA from my truck (generic BB charger).
So, 427mA, 511mA & 525mA respectively?

Here are some real numbers (the 2X is close, but not quite)
Batt_chg_current: 1102
Measured: 600ma
Batt_chg_current: 814
Measured: 450ma
1.8X actual current equals Batt_chg_current is more like it.

so it is half of what the widget actually shows just to clarify.
Yes, but it is not the widget's fault.that is the actual value stored by samsung. Other phones may use this value too and display it correctly or samsung may fix it later.

It depends how accurate you want to be. Actual measurements show more then half by a decent amount.
So let me get this straight. My 1a charger which the widget reports as 1100 is putting out 1/2 of it's rated ability. The 1a charger in my car that is being reported by the widget at 860 is wrong as well? I have tested two other chargers and the widget is reporting the charger's rated output +/- 100mAh. So are all my chargers rated output all wrong?

Nope. 2 things determine how much current a phone uses.
1) The maximum rated output current of the charger. If the phone pulls more, then the charger will only output to the max rated current.
2) The phone will only pull what it is programmed to. There is typically a built in regulator circuit (could be in SW, HW, or a mix). In the case of the Vibrant it looks like it is around ~600mA which is based on the measurements folks have taken with 1A chargers. There is a reason why Samsung provides a 700mA charger for the Vibrant.
This all assumes that Samsung hasn't messed up with the batt_chg_current file value. The only sure way to measure what the phone is pulling is to get a proven >1.2A charger and hang a digital multi-meter in series and measure the current.

Additionally, charging a battery without destroying it, or causing degradation is a science too. You can't just dump as much current as you want into a battery - you have to take into account heat and internal resistance of the battery. Samsung is using the phone's circuitry as the smart part of the battery charger, and they have imposed some sort of upper limit on current. Hot batteries charge slower (if using a smart charger), so it doesn't matter about the amperage of a charger if the battery is hot. If you are doing GPS, Maps, BT and other things in your car, your battery will get hot and charging (even a wall charger) may not keep up with discharge.
The widget is reporting a number in a file - it is not reporting mA - we know this for 2 reasons:
1. someone has measured actual current with Ammeter and posted it along with file values
2. a charger can't put out more current then it is rated for (well maybe one could but not all)
There is still value in buying a 1A charger as most other car chargers just put out the USB amount of 0.5A
I've been doing some reading on this and can't seem to find the proc in sys for current_now...which shows battery drain in mah or micro amps (which ever it reads). That's how the Nexus version of Current Widget shows charge, draw, or a net gain. I'm assuming this is because of the Vibrant Kernel?
I'm trying to take the charge and deduct the current draw to see what my net gain or loss is charging (or discharging). I have gps, bluetooth, display and media going all the time while driving.
If I can't figure it out I'm going to take an AC/DC converter, plug that into the cigarette lighter and just directly wire it to the battery *poof*.

Hello
First of all, im sorry if this is not the right thread - please correct me if im in the wrong place?
This is my first post on XDA.
I must say I love this forum, since I just got my first android, HTC legend.
I have no problems with the batterylife on this phone, but it seems like "somthing" is wrong!!??
I have tried the currentwidget and have logged usage (1 minut interval) for a couple og hours. I have logged both mah and apps running. Most of the times it says that im using 90-100 mah when the phone is on standby. It has been down to 12 mah only a few times.
Due to this, im now charging via usb at work, and this is where my problem is. The phone is NOT charge... well i guess its charging, because the orange led is on, the icon is flashing green etc. BUT it keeps saying 64% and it is not going up, it is sometimes going down to 63% even in standby.
To find out if its maybe a faulty usb cable i need to see how much current is going in to my phone when charging, but i cant seem to figure it out, even though all of you say that the currentwidget shows use of current or input from charger - do you know how to do this?
If anybody knows, please help me.
Thanks in advance
Glenn

Kinda the wrong thread and the right thread at the same time. The problem is likely due to the USB port on the computer you're charging from. Have you tried charging on a different USB port? Also, if you load the widget while charging, what value is it reporting?
Some USB ports are unpowered, which means they really won't charge anything and some devices won't work on them. Others, for whatever reason, provide only a small amount of power, which may be just enough to keep up with your phone's battery usage but not to actually charge it.

Also possible that it is the cable. Are you using the stock Samsung cable and charger? That combo should get you ~1100 in the widget. If your using adapters or extension cords take them off.
Best way to check for a faulty cable is set the widget to update every second and wiggle around. If you see the current value jumping around a lot (e.g. from 100 to 800/1100) then it is the cable. The cable can have trouble near the micro USB plug or the actual cable itself.
On the USB port make sure that you have the Samsung drivers installed. They are available in the DEV area.
Finally it could be your chargers. I had some really bad/cheap ones that did around 400. I've also had a car charger that started at 1100 and then drop within seconds to <200.
Has anyone passed the information back to the original app developer? I've gotten 3 app updates for the original app since the OP first posted this modified widget. The original app developer is open on supporting other phones.

I am very annoyed about the charging abilities of the gnote cause when it's charging It continues to use power only from the battery, can't even take out the battery that the phone turns off while connected to the charger.
This leads to the battery discharging even when connected to the charger under heavy load usages such as playing 1080p through MHL, at least to me that happens, I wonder if same thing happens to other gnote owners? (I tried a 2A charger with the MHL and it doesn't discharge as fast, but still does, and I haven't tried yet cause i didnt find the Y cable on sale to do it, but i wanna get a Y microusb cable to connect 2 chargers at same time, one to MHL device and another to the gnote to see if that helps).
So i was doing some light reading on the gnote's smb328 charger circuit and according to their diagram (and from what I understand of it and their datasheet, I can be wrong ofc) the system should indeed be able to be powered by the charger alone.
The smb328 has a missing battery detect function and loads of settings that can be programmed on the fly through the kernel (I think) and through a windows program.
Now i don't know if it's that missing battery function or some other similar thing that doesn't allow the phone to remain on while connected to charger without battery, but whatever it is I guess if that could be circumvented it would also mean that the phone would also be powered by the charger instead of the battery alone.
So does anybody more knowledgeable in these things know if there's any setting to change the behaviour of the charger circuit to allow removal of battery while connected to charger or simply allow the system to be powered at the same time by the charger and battery so that under heavy load circumstances the battery wouldn't actually discharge?
Or is it the way that Samsung physically assembled the hardware that doesn't allow it?
Just throwing and idea to the air, but could a mod, like shunting 2 of the battery's pins or something similar allow to share the charger's power to the system?
Regarding the windows summitmicro smb328 program, you think it would have access to the smb328 circuit in the gnote if we tried?
Hi Elusivo,
I'm busy to fix my Note's charging circuit and R619 seems to be shorted. I've bveen all over and cannot seem to get the value for this register.
The datasheet I found from he summit site (from your link) does not help at all. Do you have a data sheet with an application note which specifies this value?
Help will be appreciated

I would like to find out what the speed of charging of my phone is. I had an app or the Galaxy Phones that would tell me the rate.
I bought a charger from Amazon that promises that it would charge the fastest possible in my car, but I want to confirm it. Is there an app out there?
thank you
I use "Current Widget: Battery Monitor" from the app store. 'Shows both charging (when plugged in) and discharging (when not) current.
I haven't found current widget accurate since about Gingerbread. It seems to show input minus output.
Surely the simplest solution is the plug it in for a while and see how fast it charges, no?
I've never found those apps to be particularly accurate, personally.
