Question about droid bionic - Motorola Droid Bionic

i have noticed that the droid bionic, i don't know if it is just mine but i have notice that it is sensitive when i comes to chargers. like i have this charger that runs on 4 aa batteries and it goes to a plugin usb tip and it charges the usb device, when i use this charger it does seem to notice it at all and it does charge my phone. also i just built this car charger out of pieces and it works but once again my phone does not notice it. can it be forced to notice it or something like that through an app. can some one help me out tell me what is up im running my phone on stock rom and its rooted.

Have you checked the power output on the charger that you made? The output voltage may be out of spec and the phone is refusing it. Stock Motorola chargers output 5.1v at 850mA. Bionics are a bit power-hungry so if you're not putting out at least that much juice you're going to have a problem.
There's not going to be an app that can change something that's a hardware-related function. Either the pins are receiving power or they're not.

well the charger i made has 4 ports two female normal usb and the other is a micro plug and a mini plug i check the power on the female plugs and they are doing 5.3 i think and i have no way to check the micro and the mini but i would think that would be the same and the charger that is on batteries is 6.? v.

Well it appears the problem is not with your phone, but with your chargers. I suggest you get some sort of capacitor that will allow the power to build up to what the phone requires in order to charge. At least it should work in theory. Never did do the greatest in that class.

Car Charging Problem?

Anyone else having trouble with their car charger not charging their at&t tilt? I have 2 aftermarket car chargers from cellphoneshop.com and having problems. Im using DCS wm6.1 v1.5 rom and radio 1.64.06.04. I plug the charger in, the red light on the charge goes on, the orange light on the phone goes on, the battery status from quickmenu in the top right corner blinks on/off, the phone says its charging, but the phone isnt charging. The battery is going down like it normally would while all this is going on. Ive tried 2 different car chargers on 2 different vehicles and still the same problem. I dont believe its the car chargers since the 1st one i used is the one ive been using for the past 3 weeks now with no problems and the second car charger i tried is the same as the first but brand new out of the box both with the same problem. I just flashed to this rom today and this is the first time trying to charge my phone with this rom via car charger so maybe its just the rom? Im stuck at work til 11 so i cant test it on my usb or home charger til then. Any ideas or do u guys think its just the rom? Thanks! Ive never had this problem with duttys 2 newest roms, just this one i flashed back to today.
Sometimes the orange charging light on the phone will flash on/off super fast! Also sometimes the orange light will disappear and while its off the phone will still lie to me and say its charging.
is there anything running on the phone when you plugged it in? my phone wont charge after i've been using 3g for some time and it heats up. also is there any other device you can test the charger with?

Yes, i have java, hotmail, and palm messaging on in the background but having programs on in the background never made a difference before nor did being in 3g coverage which is what im in 95 percent of the day living in southern california. No other phones to try the chargers on. Ill try turning the phone off for a bit and charge it and see what happens. That would determine if the coverage or backgrounds apps are stunting the charge.
Im convinced its the rom now. When the phone is powered off the orange light is there showing its charging then after a few minutes disappears. I then unplug the charger and plug it back in but this time instead of an orange light theres a red light that stays on! I then unplug the charger and the second i unplug it the red light goes away and the phone turns on by itself. I dont think a simple car charger can do all that to a phone. I really liked this rom too. Oh well, just gotta charge my phone when i get home on the home charger if that works and reflash back to duttys march 08 rom.
Anyone else have similar car charging problems?
SOLUTION
It's not the ROM, it's the charger. Generic chargers are not wired the same as HTC chargers. HTC shorts pins 4-5 on the mini-USB end of the cable signaling the phone to enter into charge mode. Normal mini-usb chargers don't and so it's intermittent. If you purchase an HTC charger OR modify a cable the problem will be solved.
If you have other HTC phones, you'll see similar issues, especially when the battery is <10%.
The phenomenon is pretty well documented elsewhere on this site.

Huh, you could be right because the stock home charger that comes with the phone works perfect charging. So do i have to buy a ridiculus $40 car charger then from at&t? Guess its too good to be true when the generic is only 4 bucks.
i use my car charger all the time when i am driving and i dont expereince any of these problems... aside from the fact that it chrages slower then the AC charger but its understandable...

Ive never had problems though with these generic charges with other roms and yes i've charged my phone from 0 to 100 percent on the generic car charger i have before. This is the first time ive charged my phone with this rom and with the car charger so thats why i would say its the rom since it has charged many other roms perfectly. Do you know of a good place to buy an htc offical car charger? The best i've seen on the web so far is 25 bucks.
I'm going to get one of the USB car chargers.
Even the chargers ATT sells can fail. They are just repackaged junk for the most part with low current ratings.
$25 is pretty good for an HTC charger. Highly recommended to go this route.
Those who have success with the generics are just lucky as the chargers don't meet specs. The odds are good that it will let you down someday.
As I mentioned above, there's a lot of info on this topic already posted elsewhere on the forum.
Got an official HTC Charger (in at&t packaging even) from eBay seller "NakedCellPhone" for $10 + about $5 shipping.
They're marked as for the Cingular 2125 & a few other older models but it works perfectly.
DOES THE HOME CHARGER (ac) WORK???
If so, it DOES & only USB to PC or Automotive charging is affected, you've most likely damaged your USB port pins while trying to soft reset.
Take a look at the USB port on the device. If it is curved or lower on the righ side, congratulations, you are both the Perp & the victim. The USB port was poorly placed by HTC, & the stylus was poorly placed by you.
Sometimes it can be (very gently & at your own risk) bent back into shape depending on which one of the two usb port versions your device has.
BTW, if you have a business account they are only $15.00
Not all chargers are the same.
The stock OEM charger has a rating of 1A. Most car chargers that I have seen have 500mA to 800mA rating. In most cases, with these lower current chargers, you won't notice a difference except for possible longer charging time. Though, if your battery is really low, <20% or so, your car charger may not work.
I have experienced this phenomenon not only on HTC devices like the 8925 and the 8125, but also the Siemens SX66 as well.
As a side note, I've read somewhere that charging using a USB cable to your computer allows for 500mA, UNLESS the PDA is syncing through ActiveSync when the PDA asks permission to draw 1A of power. If I remember correctly, the OEM charger shorts a couple of pins to simulate this situation, but of course, the power converter/inverter is also rated at the higher current as well.
I'm not sure shorting the pin on a lesser rated charger is going to have much effect, except possibly breaking your device or cable.

I just don't understand how the generic can charge my phone everyday for almost 3 weeks now then all of a sudden stop and acting so weird, see posts 2 and 3. Then i try my second generic car charger right out of the box and does the same thing. Yes, my phone charges perfectly through the usb on the computer and the home charger it came with so i dont think its the port on the phone thats messed up. Guess ill have to invest in an official htc car charger and see how it goes.

The 2 last pins on the right side are down just a notch from the rest of the port but its pretty much always been like that, even when the car charger was working. Only having problem with the car charger, computer and ac charging works fine. I'll try to move the pins up and align them but its so minor how much they are down.

You guys think this charger is worth a shot or just pay the extra 20 bucks for the official? http://www.semsons.com/hipocarchwim.html It says its power output it 850mA!
Here is the cheapest original htc car charger i could find, www.talkietech.com/htcvecarpoch.html Heres some specs, OEM HTC Car Charger (81551) Features:
HTC Cell Phone Vehicle Charger allows phone to be charged on the road
Original Genuine HTC car charger guarantees maximum durability and performance
High quality aluminum brushed LED indicator light
Part# 81551
Compatible with:
HTC Cingular 8525, Cingular 8125, HTC Cingular 2125
HTC T-Mobile Dash, T-Mobile Wing, T-Mobile MDA and T-Mobile SDA
HTC T-Mobile Shadow, HTC Touch, Sprint Touch
It doesn't say though it works with the 8925 or tilt, would it still work on my at&t tilt? I think it would since my tilt's home charger charges my 8525 fine. What do you guys think?

I can garuntee they didn't come "down just a notch". There ar multiple threads about this issue. Sometimes it causes auto chargers to fail completely & somtimes it just causes a bad connection.
When the device was new, it was straight as an arrow. I know this because I have a TYTNII & a Tilt & this happened on the Tilt. I would drive into the local store & tell them you are having charge issues. They'll let you test out one of the stock chargers, & if that doesn't work, then it's a connection issue because of the mis-shappened port. The pins in the USB port are pretty small. It does NOT take much deviation for them to lose good contact. It also happens more frequently on the devices that have the open ended pin block.

[Q] Faster USB Charging?

Just reading up on USB chargers, and I found somewhere in a thread here about phones defaulting to smaller ma when charging via USB if the connector didn't have the data pins shorted or something.
So, I was wondering a couple of things:
1) If the default charger supplies 700ma, do you think that is the most the Nexus S can draw? Does anyone have one of these shorted USB chargers? Does it charge the NS faster?
2) If it does charge faster, how hard would it be to do something similar to shorting the data connections? I have a generic AC-USB cable which I currently use for my iPod touch.
3) Is there a way to check if it is already shorted out? The USB charging port looks similar to ones on my computer, but I'm not sure what to look for.
Thanks for any help! Maybe if we can sort out this stuff, we can provide a solution for those looking for faster charging!
it does work safely, i'm using a 1000 mAh charger at home, and a 2000 mAh charger in the car both are from aftermarket eBay/DealExtreme charges.
no overheating
and charges faster than stock

Ok thankyou for that AllGamer, I'll think of possible ways I could mod the charger now
The only reason it is slow is because of the USB charging brick instead of just a charger.

Nah it's not the wrong thread that was one of my questions! I'm not sure exactly where you would do it, but maybe if you skinned the wire, then cut the data lines it would work?
Not sure which end you would do it on however, but that may not matter. Any other ideas?
The two center pins in the USB carry the data. If you pull them out, the cable won't be able to connect to the computer.
Sent from my Nexus S
Wow - you don't need to do this and you wouldn't want to in a computer anyway.
The USB specification says that 500ma (@ 5v) of current should be available from a computer's USB port. Of course, the actual wires can carry much more than this, so manufacturers can tell their phones to takes as much current as is offered.
Almost all computers limit their USB power output accordingly - this is why some opld usb-powered external hard drives needed 2 USB plugs to get enough power. The only computers that I am SURE emit significantly more than 500ma on their USB ports are first and second generation MacBook Airs.
Some phones, the N1 and every other HTC specifically, look for a specially shorted cable to "know if they are plugged into the wall adaptor" as opposed to a computer USB port. In reality, this is just a way to make you specifically buy HTC chargers as opposed to third-party off-brands, because plugging one of these phones into an off brand charger will limit the current draw to about 450ma.
If you want to know if your Android phone thinks that it is in "USB" mode or in "AC" mode, just plug the phone in, open the dialer, enter *#*#4636#*#* and then select battery info. If your phone is one that cares (not all do), it will say USB if it thinks it should be in USB charging mode, or AC if it thinks it should be in AC charging mode.
I would not try shorting out the middle pins in a cable and then plugging it into the computer. First, most will probably just disable the USB port completely, shutting off even power you could draw. Second, if it doesn't shut down, you run the risk that a badly-built USB port might not properly limit the current to 500ma - and since they are not designed to furnish more current than that, you might melt something expensive or start a fire. third, if you make a mistake, you risk shorting out either your phone or your computer, which might ruin your day, week or month, depending on your financial means to replace the system that cooks itself.
I would just run out to your local store, pay 15 bucks for a 2A third-party usb charger brick, and go to town. That will work perfectly - this is what I use, and it probably cuts the charge time by 30-40%. Obviously, this indicates that the NS is not capable of drawing a full 2A - I have not put a meter on it, but I would bet that it limits itself to somewhere just under an amp in.
I have recently bought both a 2A wall charger and car charger and my phone does not recognise either of these as anything more than a 500mA source.
Is it really just a case of opening the car charger up and shorting out pins 2 & 3? they are currently not connected to anything in the charger.
If it's indeed a matter of shorting the data lines, then I think you can skin the wire as suggested by others, but then cut the data lines, short the end that leads to the phone, leave the end to the computer open. I think it's the phone that tries to determine whether the data lines are shorted.
Edit: Can someone measure the continuity between the data pins with the stock charger? I wonder if they are shorted. I'm still waiting for my Nexus S to arrive, so can't test it.
Yup, the data lines in the stock Nexus S charger ARE shorted.
I just modified a cheap 1A car charger by popping it open, soldering the 2 data lines together and putting it back.
The report on the Nexus S before I did this (*#*#4636#*#*) said "USB", and afterwards it now says "AC".
I will report back after I make a road trip if this improves the GPS + Pandora + Screen in car situation. I suspect it will.
----------------
Yup, the car charger seemed to actually maintain and increase the battery this time. Seems good.
The NS supports chargers output to a max of 1000mA, as it says on the back of it, where the battery resides.

[Q] Cheap replacement USB cable?

Hi guys, I accidentally left my charger and USB cable at a friend's house 700 miles away during a visit. She sent it back to me, but it's been a bit over two weeks and I'm tired of being Nookless, especially with all of the new stuff developing (cyanogen on the way? AWWW YEAH!!).
Neither of the two BN stores near my house have replacement charger/cables in stock and it appears that the BN website does not either (not even a price listed, just a pic/description).
What is the cheapest way for me to get some power in this thing? I wouldn't mind charging solely through USB. Is the stock NookColor USB cable any different than a normal micro-usb cable? Can I just order a normal $2 cable from amazon and expect it to charge?
The cable that comes with the NookColor differs from a standard micro usb in a couple of important ways: It has extra pins to deliver a higher charge. OK, I guess by "a couple" I meant "one that I am aware of." Alright, maybe one more: The charger itself is rated at .5A, which is higher than the standard plug for usb chargers.
You might be able to trickle charge from a standard usb. I was able to get some power, but not much.
Here's one more thing to do:
Ask the manager at B&N if she has any extra chargers and cables in the back. Here's why I say this: I had to return my cable yesterday because it wasn't making proper contact with the pins and thus was not properly charging. The manager told me that he has a heap of NookColor plugs and cables in a box because when they send units back to wherever they send them for repair or reconditioning, they are instructed to send only the Nook, and not the cables.
It's worth a try.
Good luck.
It does charge very slowly when connected to the PC...It will charge overnight if not in use..
I have some Nokia cables (from my mobile) with Micro-USB, they are loading the Nook nearly as fast as the original one. Very handy for charging in the car.
I have been charging my nook with only a standard cable since day one. My nook came with a bad cable and at the time was one of the last nooks in my area. I have been calling B&N almost weekly for over a month and they keep saying they will send me a cable but I have not received it yet. I have had no problems charging my Nook overnight. I even emptied the battery once and it still charged fully over night.
A regular microUSB cable will eventually charge the NC, if it's sleeping. No 3-hour quick-charging, though.
Does the slow charging really have to do with the cable?
On high draw devices (e.g. iPhone or Palm Pre) the charger shorts the data pins to signal the capacity for higher current draw. The cable has nothing to do with it.
I have noticed the Nook plug is longer than a standard micro USB plug, but that only means you can't use the Nook cable on another device's micro USB port.
Anybody know the potential problems trying to root with a non-standard Cable?

Is this confirmed to be true? If so, what allows a non-Nook USB cable to be used with the Nook?
I'm sure the cable itself is different, either by using the data lines as additional power lines for higher current capacity, or perhaps by adding some resistors to pull the data lines to certain voltages so that the Nook can identify when the "right" cable is connected, so that fast-charging can be enabled. I just can't quite grasp the idea that the cable is not physically compatible with other micro-USB devices.
I am able to use the original nook usb cable, my samsung moment usb cable, and others for data purposes, no issues
I have two other devices that also use M-USB for data transfer, and they work just fine.
I picked up a few of these a while back and they work as well:

I am just using it for data transfer and charging with the stock wall unit. As far s using these cables or other USB devices that using the MicroUSB interface would require some type of software driver (USB Host) in order to make that work. As far as I know at least.

Actually... .5A is the minimum for all plain jane USB ports.
If I remember right, when I flipped the charger over when I first got the NC, it is rated at 1.9A, which would make sense considering the size of the battery we are charging and at the speed we are charging it at. Hell, my Epic uses a 1A charger and it is only 1500mAh battery vs the NC's 4000 mAh.

True but.... I have been calling for well over a month and first they could not ship me one because I bought it at Best Buy and they did not have the warranty info yet from Best Buy. I finally got past that and since the week after Christmas they have been shipping me one each time I call. I have yet to receive one. I am going on 2 months now trying to get the cable shipped to me.

I don't think there are any.. I do all my ADB work using a "non-standard cable". The usb cable that came with my nook wont let ADB work right. When I type ADB devices with my factory cable I get the serial number but instead of device it shows suspended or something like that.

Here is a link for a Hi - Power USB Car Charger. It's 2100mA and can run and charge an Android Tablet or iPad at the same time. Also the microUSB cable they offer, shows "Charging ( AC) ” When plugged into my Captivate. Most just showed "Charging ( USB) ".
Sent from my Samsung Captivate with Perception 10.3, Firebird2 v0.8 #77 Kernel, Firmware 2.2.1, Modem T959TLJL3 using XDA App
.5A is nothing. Most phone chargers now are rated at 1A with ones for tablets going above 2 as someone else mentioned. Most BT headset chargers are rated at .2-.5A in comparison. Some GPS units have charges rated over 1.5A. My Dash unit had a 2A.
And if I'm not mistaken, if you're connected to a computer you will only get a tricklish charge as it's limited to .2 or .25A (I believe).
In regards to actual cables, any microUSB cable will work. I've used stock ones from Samsung and Palm phones as well as cheap 50 cent ones from Meritline. And if the Nook one is actually longer? Why wouldn' it work in something else? The cable will just stick out further.

Do you use your nook color charger on your phone?

I'm just curious. I'm not sure it's safe, since one has a 10W output, and one has a 5W. If you do, have you had any problems? Notice it charging faster than usual?
deleted +10
Yeah, that's what my phone charger outputs. The iPad/iPhone chargers have the same output as the Nook/Android phone, and they claim to be safe to use with either one. Not sure if that applies to android phones though, or if there needs to be some safety circuit in either the phone or the charger. Would love to only have to deal with one charger...
It's 5 volts at UPTO 2 Amps. If your device can only draw 5W thats all it will do then overcharge protecton etc cuts in.
I've used the Nook charger on
Nook Color
Nexus One
Blackberry
Plantronics SteroeBluetooth headset
No problems.
As long as the voltage is correct you are good to go. The phone draws amps from it, it won't draw more amperage than it needs.
I noticed that my nook USB cord doesn't fit my Motorola Droid 1, however, my Motorola Droid 1 Phone charger fits my nook :\
Anyone else confirm this?
Also, when plugging in the nook I get no indication that it is actually charging, is this suppose to happen?
EDIT: It appears that it doesn't charge when I plug it into my computer, if it is, it is super slow and doesn't display that it is charging. However, when I plug it into the wall with an A/C USB adapter it shows the charging icon.
from what I got, The nook charger has 6 more pins making it faster, but not compatible with other devices, but the nook itself can get a normal charger and it will be fine just slower.

Except the 6 pins (or w/e num) are added on top of the existing ones, so unlike say a headphone jack with an extra layer for using a microphone, its not backwards compatible (atleast not without an adapter) for normal ones (like my headphones example), rather troublesome imo.
But the power converter works fine for phones.

As long as the voltage is correct you are good to go. The phone draws amps from it, it won't draw more amperage than it needs.

Thanks makes sense.
Just tried it and it works fine on my phone too. Has to use a generic micro usb cable though. The nook one did not work.
I wonder if the reason the nook color cable doesn't work with other devices is due to the charging light built into the cable. I'll try charging it from a non-nook cable to see. If it charges fine either way, I'll be able to cut it down to 1 charger 1 cable. Would be far more convenient.
Has anyone else noticed a slower charge on non-nook cables? If it really does have more pins, that would be a dissapointment. The cable is so short, I'd probably have replaced it anyway.
the nook color charger connector is shaped slightly different -- its longer --, so it wont fit properly into other devices that use standard microusb.
Is there supposed to be some kind of notification when the unit is off, that it is charging properly. I bought my nook color used and it didn't come with its official charger. I have a bunch of standard (low amperage) USB chargers and 1 iPad type (2amp) charger. I tried the iPad one and the unit gave a "Not charging" message in the settings screen.
How long does it take to charge when using a 3rd party charger?

Do not resurrect dead threads, they will turn into zombies and eat your brains.
How long does a non-BN charger AND Cable take? Four times longer. It's .5A vs 1.9A. You can get by with a 2A charger, but you must have the B&N cable to charge at the 1.9A rate.

Make non-motorola charger work?

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.
