Hello! I need a little help finding an app or a tweak if any exists.
I have samsung galaxy tab(GT-P3110), the charging port is totally destroyed, so now the only way to charge the battery is to directly charge it. I opened the back of the device and extended two wires (+) and (-) from the battery socket and then put back the cover. So now I charge the device by connecting those two wires sticking out of the device with the stripped end of a usb cable.
I know this way of charging is damaging the battery or inappropriate, but atleast i'm able to use the device than just uselessly throwing it away.
When i use the device, there is no real way to say how much charge is remaining. Even if the device is charging, the device shows that the charge is decreasing like as if it wasn't charging but it is. and once i reboot, it shows the real increased charge %.
So i wanna know, is there anything i can do to get real battery stats while the tablet is still on?

I woke up to find my SDA powered off and unable to power on, which was odd considering it was plugged in to a (Motorola) charger.
Since the orange charge light doesn't come on at all, I suspect it's just a dead battery. I've touched the battery contacts to a battery tester with no response - as if the battery is totally dead, which is promising. However, I can't be sure I'm doing it correctly since I've never tried this on a battery I know is working.
There are 4 contacts on the battery, and I'm wondering if there's more to it - like needing to have 2 contacts touching the positive lead and the other 2 touching the negative lead.
Can someone try testing their battery and see which contacts give a live (charged) result?
Thanks

Normally you shouldn't try to use chargers not designed for your phone. What has probably happened is that there wasn't enough current output in the charger, and it completely drained your battery. Your battery is probably fine. Get a proper SDA charger and try charging it again. You can even take it to a store and ask them to plug it in for 15 minutes while you browse the new phones.
Yeah - I lost the original charger, but I've been charging with this Motorola one (output 5V / 550 mAh) and via USB for the past 6 months without problem. I still think it may be the battery because it was at 50% when I went to sleep.
What are the output specs of the original charger?

The stock HTC charger (model ADP-5FH K) has output of 1A at 5V. But if you had no trouble charging before it shouldn't be a issue, unless the charger/battery is faulty.
If you have a multimeter you can verify this. To check if your battery is charged place contacts in (+) and (-) contacts on your battery and it should show ~3.7V. I just tried this.

Thanks, silencer. I don't have a multi-meter, but I was using the battery tester as a way to gauge whether it was putting out any current at all, and it sounds like it's not. You were testing the 1st and 4th contacts?
I have read elsewhere that if your battery goes below 10-20% you won't be able to charge it with anything but the stock charger, so I think that's the problem, but I'll probably order a new battery as well just in case.
Yes I check the voltage between first and forth contact. What sort of battery tester are you using? Is there a digital read out display?
You can also try a USB to mini-usb cable to see if the battery get charged. From what I can remember USB ports are designed to give 500mA at 5V, but I have charged my phone when it was flat using a USB cable.
To follow-up in case anyone has this problem in the future: I ordered a new original charger (ADP-5FH) off eBay and with it, the phone's orange charge light came on right away and after giving it a full charge my phone is back up and running.
I'm inclined to think that it's not the difference in mAh of the original charger (1000mAh) vs USB charging (500mAh), but that there is something unique to the original charger which can "turn on" the charging when the battery is completely dead - perhaps something communicated by one of the extra pins in the mini-USB connection.
well not necessarily,
BUT
the phone has TWO modes of charging.
UBS and AC Charger.
USB recharges about 400-500mah
AC recharges about 900mah
This is flagged by a pin on the USB. BUT this is also flagged in the OS somewhere.
This is done in windows mobile via software hack so the OS thinks it's always on AC charger.
I'm just throwing this out there if someone can figure out what code is flagging the system to think this is UBS or AC connected.
i think the AC method just reduces the charging time, other than increases battery life. Right?

Yep. But I think that's what he's getting at. He wants it to charge just as fast while on usb. There's no way to increase battery life... other than buying a higher capacity battery.

Or using Collins Battery Tweak. http://forum.xda-developers.com/showthread.php?t=791060
you can try that but no matter what yo u cant get anymore power out a USB. if a USB does 4-500 then even if it was hacked it would only output 4-500. If anything it might damage the phone.
Only real possibility I can think of usb charging any faster is if you made a double headed usb cord (for plugging into two usb ports) it won't hurt anything, matter of fact Arduino boards can be used like this as well as external cd/dvd drives without dedicated power, and even some low power routers (like my fon router)
At either rate, even if this were to work, you have to think about how the phone itself rates the incoming power. It may have nothing to do with the actual power charging mode coming into the phone (preferable for dual usb method), but if it has anything to do with just hardware, then it is most probably a no go because of the power balancing in the phone itself.
As far as the pin solution on usb, that may very well help out. I am sure it can range on the incoming power from the plug with that.
If you carefully open a usb charging cable and short the green and white wires on the pc side, with a 200 ohm resistor, the pc will output higher amperage and not let the phone switch into pc charge mode. You will not be able to sync with that cable but it will charge your phone like your ac outlet as long as it is a usb 2.0 port.
Why not just buy a charger for a MOTO Razr? Thats why I use and it charges my phone fairly quickly, but slow enough to put more of a deep charge into the battery.
The less amperage you put towards charging a battery, will actually charge the battery "more".
My X10 battery was totally D-E-A-D .. with the battery inserted and attemptation to turn on the phone. 3 fast red led lights would blink.. to indicate the battery is too low to power up the phone.. Correct??
With the battery in and USB data cable connected to my X10 phone.. I would get a slow blinking Red Led which ive never seen before.. "must indicate faulty battery and not charging" .. anyway my phone would not turn on with the battery in what so ever. ! even tried to charge the battery using the main plug --> USB --> Phone.. and still just a slow blinking red light.
After reading up from google my friend.. I forced a USB "5v" connection into the battery from my laptop.. using a stripped down USB cable i didnt need the "red + Positive " and "black - Negative " leads.. The battery got warm i disconnected the lead. Turned on my phone and it worked with 9% battery life.. I plugged in my Cable and now its charging .. just as normal... so now i will fully charge my battery and see how it goes
Now my question is.. Would this method also work for lets say.. :/ a laptop battery that might be faulty? but obv course if i was to try i would match the volts as am pretty sure the voltage of a laptop battery and Phone battery are different..
Yes and no, laptop batteries are much more complicated in nature than a cell phone battery. The electronics in a laptop battery are what makes them almost impossible to revive.
Sorry, from the sounds of it you're saying you cut up a USB lead and just held some of the wires against the contacts on the battery?
Recently my Phone has been charging but it doesn't read as charging like, the little battery on the top right doesn't say charging and the status doesn't say charging, but the battery life still goes up.
Mind you that it only really charges on a computer, also it doesn't read usb mode.
I think the problem is the charging port but I'm thinking it could be the battery.
Anyone have any similar issue or ideas of what it could be.
I have a phone that needs to be always connected to an OTG cable which does not support simultaneous charging. So to charge the phone I soldered a small USB lithium battery charger directly on the battery pins. And it works, but the phone does not display the true battery percentage until I reboot it. I think it's because the Android system isn't aware that the battery is charging and thus it doesn't allow the battery percentage to increase, but only to decrease.
So my question is: there is a way to make the android system "recalculate" the battery percentage without rebooting the phone? Something like "resetting" the battery service?
The phone is rooted, if it matters...
