What would happen if I had my TP on the Touchstone, and I plugged a charger into the MicroUSB port? Would it charge faster? Would it get fried or something?
Why don't you try it and see? Maybe hook it up to a lightning rod and send it to the roof during a severe storm too.
It wouldn't charge any faster. It would just pick one way and use it, probably the plug in.

I have a tilt that now will charge from the USB to computer connection, but does not charge when plugged into the wall with my wall charger (an after-market charger that worked fine until today). The phone says "charging" but actually loses battery power .. and after a while the orange charging light goes off.
Any thoughts -- sure is a drag to have to charge my phone through the laptop.
What after market wall charger do you have? Does it use the USB cord to charge? I'm assuming that you plug the USB cord into the wall charger and then into your phone. If so this will not work. The USB cable is only capable of trickle charging. If you are doing anything while it is charging over USB you will use power faster than the trickle charger can provide. You have to charge it with a wall charger that does NOT use the USB cable.
Yes I realize that the standard wall charger uses a mini-USB plug but the internals of the cable are not the same as a data USB cable. The difference in juice it can provide is like comparing a PVC pipe to straw.
I was just using a radio shack iGo charger with a usb tip ... it worked fine until my latest ROM upgrade.
Ahh I see. Yep the charger is most likely bad.
When I first got the phone earlier this week, I could plug it into the charger in the wall just fine with no issues, it would just charge. Now suddenly it started telling me USB connected and goes to the MTP screen and of course locks up the phone.
I can of course bypass this by switching the phone to mass storage mode, but since I have Kies and use it occasionally, it would be nice to not have to switch that setting each time depending on my charging/syncing situation.
Why would it have not locked it up with the MTP screen originally when charging from the wall but now it does? The results are the same whether its plugged into the wall or the USB port on the computer. I have two Captivates bought brand new on a family plan, both do this now with any combination of chargers and USB cables, wall USB port, or car charger. Neither one has a common application installed since the other is my girlfriends who hasnt done much to it yet, so Im blaming the phone itself for now...

Interesting. I just checked with my BB charger and they dont do it using that charger, but they do it as soon as I connect the stock charger again.
Im wondering if its a voltage sensing circuit thats tripping due to the different voltages which should be applied - either wall charger or USB port. Maybe for some reason my wall chargers arent putting out enough voltage and its thinking its a USB port, but the BB charger is putting the right amount of voltage out?
Am I on base as to how it differentiates between wall or USB port? The number of pins obviously doesnt matter as all the cables have all the pins in them, unlike some charger cables which only have the power and ground. The only thing I can think of is that it uses the amount of voltage/current to tell the difference and create its reaction.

Sounds like a problem with the stock charger, maybe usb cable alignment. My iphone wall adapter does this with the samsung cable but the samsung wall adapter doesn't, same with my car charger from att. Also I have a $5 walmart car charger that has a cable that splits into both a mini usb and a micro usb that isn't a real usb cable, it's charge only. That cable has no problem on any wall or car adapter. I believe the phone detects if its connected by checking voltage on a data pin (just a guess really) so if a nonstock charger is used it assumes that it is a computer. But it may also be a data signal that is given off by the charger.

did you try a new charger and if so, did it work? I've had my captivate since Thursday and on Thursday it charged and everything fine, but then yesterday,
a) no computer I connect it to while recognize it, no matter what I have it set too and have latest drivers installed
b) if I charge it, after I unplug it, it locks up to black screen and I have to remove the battery to get it to work
c) I also have an in-dash touchscreen monitor in my car that has a usb port because it works with an ipod. I plugged the usb into to use it as a car charger, unplugged it, same thing
d) it did say usb connected after it was unplugged, but I switched from mass storage to ask on connection and it went away
so is an actual wall charger the solution?

and now I unplug it, and if it locks, it will not unlock, just black screen
I have to take out the battery and then only way to get it to turn back on, is to plug it back in the wall

^^^Ouch that's not right, if you can't figure it out you may need to re-flash or just bring it back under warranty, or insurance

My dog just ate my standard mini usb charger. Can i charge my phone with normal usb cable (while connected to latop/pc) or is it problematic for the battery life?
Can I use any other mini usb charger like HTC desire?

I assume this is a troll
If not I'd like to see some pictures of it.
Yes you can use any other MICRO-usb charger, not MINI. USB cable works as well
Haha! unfortunately no troll He cut the cable into two pieces, so it is completly destroyed and the connector is damaged too.
Im pretty pissed, dont have the money to rebuy a new one So ill stick with my usb connector. Just wanted to go sure that my phone wont take any damage while charging with my laptop
I connect my phone to my pc via MICRO-usb cable. It charges phone also but it's slower than normal charger.
So this is my first motorola and I had heard of the issues they have with non motorola chargers. Now I am experiencing it first hand. With the same ac charger I have charged many phones with and is capable of 1 amp output (D4 charger is only rated at 850 mA) my D4 struggles. With the device off it charged painfully slowly. While on it cannot even charge. It discharges while plugged in despite the charging indicator and reporting "charging (AC)" in status.
How does it know it is not a moto charger? Is it just about the resistance between the data pins? For most other phones shorting the data pins on the charger indicates to the phone that it is a high current charger and not a computer USB port. Is there a similar trick for motorola phones? I would rather not have to purchase an overpriced moto oem car charger. I have a perfectly fine 1.2 amp car charger soldered directly into my car's 12v system behind the dash. Can I make it work?
Thanks!
On a regular basis I successfully charge my D4 using both a charger from a Samsung Reality feature phone and from a B&N Nook Simple Touch, in addition to the one that came with it. I've also used a variety of car chargers.

Actually, so far I have only one charger that had any trouble charging the phone (it was a $3 charger with 2 USB ports), but the $3 charger with ONE USB port works fine, as does the Nook Color charger, Blackberry charger, and Samsung charger I have tried it with, as well as both my old car charger and Lenovo's always-on charging port on their laptops.

Not sure how it knows one way or the other. I've successfully used a few LG chargers to charge my D4. The only really hickup I've ran into is the usb cables from those lg chargers won't sync data to the phones when plugged into a computer, they'll still charge off the usb port but won't read as a usb connection to the computer.
Heh, captcha is trynply.
Every charger I've used, including an old charger for an EN-V, kindle, supplied, and various other phone chargers works just fine with this phone. Probably have a bad charger, guy.
Thanks for the replies. I guess I was wrong. My modded car charger works just fine. I guess its just time to retire the old charger that I have been using. I think it might be my old nexus one charger.
A more important question would be does the thing charge over computer-bound USB ports?
When you're without a charger, but there's a USB cable that fits your phone, sometimes a regular USB data port is the only that is around... even though it might take a really long time.
Try a computer bound USB port, then try your actual charger, again. Or do the hard reset (vol down plus power, hold until it actually does it), which is just like pulling the battery.
See how that goes.

It does in fact charge via USB port. In fact, it has a 'charge only' mode. Depending on how much juice your port puts out, and what you are doing with the phone, it will charge slowly/not at all, though.
from my experiences, the droid 4 will not accept lg microusb cables, the charging bricks work tho. i use a blackberry microusb on mine along with a Logitech and the stock moto ones. 1.2 amps is a bit high but not crazy sounding. personally, I charge at 1 amp.
Hello guys,
So today, I finally found out why my phone would not charge from an AC plug. It turns out that the actual plug (not the wire) is broken because my phone can still charge over the PC. However, I don't want to connect my phone to my PC because Ive already fried a USB port doing so. On the plus side, I have about a gazillion chargers (apple, LG, Samsung etc) lying around the house but I am reading that the charger needs to be a specific voltage or you could potentially fry your battery and stuff like that.
So would anyone recommend to me the correct voltage for charging the phone?
Edit: I found the voltage to be 5V. Can anyone confirm?
Last Edit: Ahahahahaha, seems like the cable is broken. LOL Mega faceplam.
