MDA Cradle Mod - General Accessories

**** Cradle mod not working!!!
I modded my MDA cradle. Didn't work out. I think that the USB bus isn't suplying enough power. When I put the MDA in the cradle it syncs without any problem and the charging LED goes to yellow, even the power meter says "charging". Strange enough after half a day on the cradle the MDA doesn't charge. It completely depleted. So I needed the charge it using the external charger.
I rececked the connections and used my multimeter to verify the power. It does supply the 5V. But I think that the 500mA is not enough to charge the 2A beast.

charging issues
Maybe you already did this but make sure that you turn off the unit while charging. Make it turn off automatically after a few minutes. It will occasionally wake up and if it's not set to shut off it won't charge enough compared to the screen draw on power. The USB 500ma is enough it just takes longer (around 8 hours) compared to the 2amp charger ~1-2 hrs.

Well, you're right I don't turn it off. I'll try that for a change.
Thanks

Niels, also make sure that you connect the MDA cradle directly to a port on your PC/Laptop, and not via a USB hub. USB hubs are known for not being able to provide enough juice.

MDA Cradle Mod and now it is charging
Got it working now!. I remodded the craddle (yes soldered again!) I connected it to my computers' 5V circuit. No problems now. I can leave it on AND charge it.

jasjar not charging with USB when is on???

Dear friends...
Do i do something wrong?
My new jasjar will not charge (even if it says charging) when is open...When I close then it charges. (the indicator increases)
Do you have any idea? Is this how it is supposed to work?
It is very unproductive.
In my experience, when the device is usb connected and the screen is On, then the jasjar charges, but veeeeeeeery slowly...
mine it says charging in the 'Settings' and goes down...65%,63%...etc.
the light is orange that indicates charging as well....

The problem is that the mains adapter provides 5V at 1A. A computer's USB connection will only provide 5V at .5A, so the Jasjar only gets half as much power when it's connected to the computer. Unfortunately, this is the maximum amount of power a standard USB port can provide.
Like dherrero, my Jasjar definitely charges when it's connected to a PC, but it charges pretty slowly. If your Jasjar is using a lot of power... maybe you have bluetooth and wifi turned on and you have the backlight set to be very bright, then it's possible that the .5A just can't keep up with the power demands. When you close the screen the backlight turns off, so that gives it more power to devote to charging the battery. Maybe try to turn down your screen brightness or turn off wifi?
Brett
The other thing I just thought of is that there are two kinds of USB ports... powered and non-powered. The powered ones can provide .5A of power, but the non-powered ones can only provide .1A. Is it possible that you have your device plugged into a non-powered USB port? Normally the ones that are directly on your computer are powered, but the ones on a USB hub are not unless that hub has a seperate mains adapter. Perhaps you should try a different USB port... preferably one that's directly on your PC.

I have tried to charge MDA Pro with the mains adapter from a GPS receiver (also 5V 1A).
It doesn't work. The only explanation is that they
did something with the ID pin. I don't think
the Universal is capable of finding out how
much current you can drive from the adapter.
You are absolutely right my friend! Disabling wi-fi and the brightness...started cumulating power!!!
Thanks guys!
The situation has improved for me over the last week as the battery has become conditioned. At first mine didn't charge from USB but now it does. I've followed the recommendation of doing several full charge/discharge cycles since I got the phone.

The same should be true for Universal, but YMMV.
It's ActiveSync.. M$ changed WM5 way of connecting by modifing the USB driver with AS4, and in doing so, I think the USB is not giving the proper currents to the Universal so when it's charging using the "modded" USB port, it charges VERY VERY slow... On the other hand, if you plug it into the wall charger, it charges up in about an hr or two max...
And you DON'T have to do the charge/discharge circle with polymer batteries....

You don't have to do this once you've been using it for a while, but the manual advocates conditioning the new battery with at least one (but ideally more) full charge/discharge cycles. New batteries have to 'learn' their capacity, IIRC.
My laptop's manual said the same thing, and because the battery has a brain you need to do a full charge/discharge cycle every couple of months to re-train the battery's electronic brain with the true capacity.
Certainly my Exec now has much better battery life than it did after its first charge...
Jasjar battery
I have a different problem. I used the AC adapter to charge overnight (I had been using the USB port to excellent effect). When I attempted to powerup the jasjar it has been unresponsive.
I plugged it into the USB port, but still nothing.
Tried both soft- and hard-resets. Nothing.
Left it plugged into the USB port and took out the battery and the LED on the right side glowed red (as it would if the battery were discharged) but the unit still wouldn't respond to reset commands.
When I put the battery back in the LED went out and the unit became unresponsive again.
Any ideas?

Sounds like a knackered battery, Rich.

I'm not sure that fully discharging the battery is a good thing. I saw a comment on one of the RSS feeds on Buzz Lightyears site from one of the MSDN guys who actually said that fully discharging the battery was harmful to it.

Yeah, I know what you mean. The thing my laptop manual says (which I guess applies to the Exec too) is that the device will turn off before the battery is completely flat, since the battery can't sustain the minimum voltage required to keep the basic functions alive even though there's still some charge left in it. Therefore the battery is never fully discharged, like it would be if you shorted the terminals.
I think it's the full (e.g. shorted out terminals) discharge that hurts the battery.

in the hp manuals its mentioned:
" if you charge via usb and the screen is on, the device will consume almost all the power from the usb. it will charge but at a very slow rate."
i suppose its the same with the universal

speed up usb charge?

Im a long time lurker, and been following alot of posts... let me just say that you guys really are geniuses...this is day 2 of having my tmobile tp2.. and i been reading your forums since yesterday morning non stop....
If you have the time im interested in this...
1- i seen a post on speeding up the time your usb charges your tp2. But didnt see the cab or the reg edit string.. if there is one... is there?
2- info for adding items, or removing "call history" from home screen? maybe replacing with more comon things like messaging...
3- any way to constantly keep a stock listed in the tf stock tab? instead of always having tgo type in the same stock?
4- i just bought tt6 for an older phone...obviously it wont work with tp2. and i dont want to pay $ for a new program. i spent it all on teh phone..
does WVGAFIX3 work? or any other programs top change res before starting TT6?
5- with out downloading or running programs.. when on homescreen, "camera" and "allpeople" are always on the bottom green bar.. can i replace them with somethign more usefull?
seriously....you guys are awesome...
Would also like to know how to speed up USB charging. Think i read somewhere you get 1000mah per hour with the charger and 500mah with USB charging.
yeah, home charger that came with the device is rated on the make as 1A, or 1000mah... and i do know that usb is 500mah.. or .5a standard..
but when using my tp2 while connected to usb, it sometimes gets a pop up message saying charge supply insufficient...
perhaps cable doesnt fit well in the phone? either way, usb charging is very slow...
USB ports on a computer cannot output more then 500Mah. this has nothing to do with the phone.
the Wall charger can only output 1000Mah, again, this has nothing to do with the phone. just the way it is.
if you wanted to charge the battery faster you could get a battery charger for Rccars. you will not get the battery to charge faster through conventional means.
FYI, the fastest you can safely charge the battery in the Tp2 is 1500Mah. (1C) or you will risk damaging the battery and limited recharge cycles.
By any chance are you sharing the same USB port with other devices through a USB hub?
not sharing any other devices on the usb port....
what you say makes sense, and i wouldnt use a charger more then 1000mah... not worth the risk...
MAYBE its all relative since working with it in hand constantly and charging usb wise...
ill actually test mine tomorrow and time how ling it takes to charge usb from 0 to 100%
just a note : current is measured in Amps or milliamps (ma) , mah is milliamp hours and refers to battery capacity. Chargers output ma , not mah.
Getting the insufficient power popup when trying to charge via USB means the computer isn't giving out enough current to the USB. Try using different USB ports... i've known some USB ports are able to give more power on the same computer... depending on what header theyre plugged into on the PC motherboard.
Try to find an original HTC Universal (Imate JasJar etc.) charger. It is rated for 1500ma. I use it once a month for my Touch HD (a somewhat higher amperage recharge can condition a weak battery but it gets pretty hot....so beware!) and I am still using my HD (9 months old) like it is new.

Hi Loueber,
in regards to point 4 I have used WVGAFIX3 with TT6, it basically swaps you phone to lower resolution leaving a black bar at the bottom of the display. But it does then allow older QVGA apps such ass TT6 to be run.
Hope that helps
This program should take care of you: http://www.nuerom.com/BlogEngine/page/nuePowernueBattery.aspx
without that the USB hub will only power up to 500ma, with that it'll go up to 1000ma like it would off a wall charger.
Not from USB, the wall charger offers a slightly higher voltage, and from that the phone knows it can draw down a higher amperage. The Nuerom power driver will maximize the power you can draw from USB, but it still will not draw over 500ma from USB.
Even if split the four wires from the USB charge cable, and hook power wires up to a 5.1V 1000ma wall charger, and the data wires to your computer it will STILL only draw 500ma. The phone has multiple different safety mechanisms to prevent draw of over 500ma from a USB port.
In short, the only way to charge at faster then 500ma is from a wall charger. Unless somoene hacks the power drivers for the TP2/Rhodium in a way that contravenes the built in safety mechanisms.
I used a female to female usb adapter.. usb to mini-b adapter.. and finally a Y adapter that came with a cheap (10$) SATA-to-USB hard drive enclosure.. It allows the HD to pull max current and not operate in wimpy .5A mode. This is useful for 7200rpm 2.5 inch hds.. but I digress.. One end is data+power, another is power only.. Pull the data plug and the charging light remains constant.. That tells me the TP2 is utilizing power from both sources. The same works for pulling the power-only plug.. I'm tempted to hook up the data port to the wall adapter and test out that 1.5A someone mentioned earlier..
I'll try it out tonight..
btw: I'm currently looking for a program to show me the power input.. So far, tbattery isn't playing nice with my 1% battery driver.

Doesn't the previously mentioned nuePower control panel app do it?
There is some misconception on this.
In the USB connector at the phone, there is a pin that if grounded tells the phone to charge at a max of 1 amp. If it is floated, it charges at a max of 500ma. If you go over 500ma, you risk damaging some laptop USB ports, thus the reason for the limit when using a USB cable. The supplied charger grounds that pin and goes up to 1 amp.
So it doesn't matter if you have a 5.1 volt supply, or a 4.9 volt supply, or 1 amp available or 20 amps available. It will charge at 1 amp, or 500 ma. max depending on the charge mode pin.
The pinout that I have calls it pin B. It is the pin next to the ground.
http://www.hardwarebook.info/ExtUSB
I don't recall where I got it, but I have an inline plug that I can insert in the USB plug that has a switch. Flip that switch, and the current goes up to 1 amp from the USB port.
Theres a program called batteryinfo.exe located in \Windows. Its pretty simple.. but it does show the info I need. It does create a log file in \.. Safe to delete whenever (assuming app is closed). So far, I haven't seen anything above 1 amp.. Theres discharge current (how much mA your device is using) and charge current. They usually add up to around 1A.
This NC pin.. if this were grounded by the HTC AC adapter, wouldn't the other end (USB) of the cable have 5 pins?
I have the htc AV connector.. I'm sure that has all the necesary wires in the jacket. I don't want to cut it up yet tho..
It would probably be better to cut up a 'dongle'. I would make an rj45 connector for each row of pins. Once you have some cat5/5e/6 cable to play with, the possibilities are endless..
Any more info on this nc pin?

not charging via usb?

so the option to not charge it is not ticked under power settings, and its set to charge via usb from advanced config and still no dice.
tried different usb ports and nothing
the led is orange, says its charging in power options
any thoughts?
Try a diffrent usb cable, some cables do not provide enough power to charge the phone. (guessing maybe they are old 1.1 cabels). But I know I have a few cables around that dont charge my phone and they also will not work with my portable external usb hard drive because they wont provide enough power for it. But they work just fine with my digital camera.
I´ve read somewhere that disabling USB charging is better for the battery life, so I have it disabled.
You've tried different USB ports, but were they on the different computers?
so i've tried different cables, different ports and 2 different PC's and 2 different laptops.
I know its not the cable i'm currently using because i plugged it into one of those A/C to USB adapters and charged fine.
I'm starting to think its my batter,
If you have tbattery installed, do u get values for all the boxes?
All mine except 3 or 4 are 0 :/
Well, you are not the only one having this problem. Mine is brand new. I started setting it up last night and had it hooked to the computer via usb. I installed a few .cabs such as google maps, myphone, and a few tweaks such as tether, disable sent notification, enable all camera modes, and manila start menu unlocker. While it was connected it said it was charging. When I went to bed I turned it off and connected it to another usb cable on another computer which is an a/c hub. I went to turn it on this morning and thought it was strange it was not fully charged. I continued to set it up a bit and take it for a spin. After a while I turned it off again and hooked it to the usb a/c charger again. I just tried turning it on and nothing was happening. I connected it to the usb again and it finally turned on, but I checked the battery level and it was at 0% and turned off. I have it connected to the a/c charger and giving it a little bit to see what will happen. One thing that seems strange is that the battery discharged more while it was off and attached to the usb a/c hub during the afternoon causing it to refuse to turn on at all. Any thoughts?

I think the odds are pretty good it's your battery. The orange light means power is going through the charging circuit, so you obviously have your settings correct.
I'm guessing you're in Austin or near? If you want to try popping my battery in it for a few minutes and see if it charges fine then, PM me and we can set something up.
the same thing is happening with mine. Sometimes it will charge, sometimes it wont. weird thing is that it only started doing this a few days ago... i know nothing has changed ROM wise, so only things i can think now is maybe the actual USB connector on the phone or the battery, but since I am getting a charge via wall chargers im not sure what to think lol
Just an update.
If i have the USB cable plugged in (and car charger to which doesn't charge as well ) after 15 min or so a warning appears saying that the current is too low to charge the device. Either closed unused apps or switch to a/c power.
I've ordered a 1800mah Mugen Power Battery. Gonna see if it resolves the issue, if it does then i'm gonna call at&t and see if they'll swap my battery for me.
I have found as have others here after reading some posts that if the phone is almost dead or battery is very low then it will not charge via the USB anymore. The orange light goes on and it says that its charging but the charging circuit seems to be protecting the phone and not letting the battery charge.
The only solution I have found, and it has only happened twice so far is to plug it into a wall charger and fully charge the battery. It will then charge via USB again and all is good. I normally only charge my phone with usb while connected to Activesync but once in a while you seem to need to top it up with a wall charger.
It is also highly recomended not to run Lithium Ion batteries right out.
How do you know it is not charging?
There is a difference in the wiring from a wall charger and a USB charger. There is a signal line in the wall charger telling it to charge at near 1000ma. In the USB cable that line tells it to limit the charge current to 500ma. That is the limit for current that you should pull from a USB port. If you are using the unit heavily, you may actually need more then the 500ma., those running the battery down possibly.
If the unit is idle, it will still take much longer to charger from USB then off of a wall charger.

If you are asking me, I know it was not charging because I also had the "not enough power to charge message" and the phone went from about 15% when I plugged it in to stone cold dead by the morning. The whole time it was pluged into a computer I have used repeatedly to charge it with. I then put it on a AC charger and it went to full charger in about an hour and a half or so.

Phone charging and Satnav...is this normal?

Just been on a long run and used the satnav ( google ), and the whole time it was plugged into the cigarette lighter charger.
Despite this, the battery level was running down
Is this normal - that the battery drain using the satnav/gps is greater than the charging rate?
I used mine yesterday for about a 1/2 hr journey, was not plugged in, but batterey was down to about 30%, also seemd to use about 20mb for 15 miles, so watch your usage.

Its been discussed already, your charger is not powerful enough to charge it when using satnav, so the end result is that your charger is just slowing down the discharge. Happens when you are using 3rd party accessories.
Ah - That makes sense -- where can I get a decent one - at a decent price
I'm using the factory supplied lead and still get the same, also used to be a problem with my Touch Diamond 2 WinMo Phone, was hoping Desire would be better and it is... just... If I make sure it is fully charged before I set off I can do about 3 hours with it plugged in before it goes flat, I just keep switching it off while I know where I'm going and only switching it on when I don't! That way you can make it last until it is needed.
Another thing to check is that it is kept cool enough to charge, again, in common with my older HTC winmo phone, the Desire gets very hot while being used for GPS and this can be worse if it is in sunlight on your windscreen, sometimes this can stop it charging at all, (you can tell its in this state because the indicator light blinks alternately orange and green) I angle a vent so its blowing cold air on the phone and that seems to do the trick.
Weird thing with the Desire is that for me it shows the green charge light and battery full indicator right up till it is nearly dead... rather than showing that it is draining
I've also noticed with the Desire that even If I'm just browsing the web it drains quicker than it can charge, even using mains charger, I often get a message "the current is insufficient, please connect to AC" or something like that (when it is already plugged in)
I don't think the in car charger you use would make a big difference, the current/voltage for your cigarette lighter socket is limited by the vehicle electrics (I know mine is fused at 15 amps)
Pauly
You need a charger which supplies 1A. Most 12v cigarette lighter chargers only supply 500mA
I use this one, and plug the USB cable into the "quick charge 1A" socket

Are you using Bruts worldwide maps mod? I just installed it. I ran it for literally only 5 minutes, but my phone got really hot and the battery monitor shows the app used 10% of the charge (the phone has been unplugged for 24 hours). I have a strong suspicion that this app is faulty.

Basically most usb car chargers (even 1a rated ones) are recognised by your phone as a data connection and to protet delicate computer usb circuits will only draw 500mAh where your phone requires 950mAh.
An easy mod of either the charger or a data cable will solve the problem. Your charger MUST be able to supply up to 1a.

Thats why I use the Belkin one, it detects it as a charger only and charges at full rate when plugged into the 1A socket.

Drained Battery ONLY charges from wall charger?

Anyone else notice that our Nitro is rather fickle about the power source it receives?
If my battery is completely drained, it MUST be plugged into a higher power source than USB (so far a wall charger that ouputs 750ma works) until it gets an initial charge (usually needs at least a couple of %)...Then it will accept charging from USB (USB provides 500ma).
I can tell when it's in this "state" because it remains dead if I plug it into USB and then if I plug it into a wall charger the touch buttons at the bottom flash for a few times and then the LG logo pops up and finally a charging battery icon comes on. Considering this sequence, this seems like a functionality of the phone. I wonder if this is common, my Nexus One certainly didn't have a higher-initial charge rate requirement when the battery was dead.
I've experienceed the same scenario.

I only have chargers that operate 1.8amps and higher.
As the battery is an issue the higher the amps the faster it will charge

Well I did notice that if it was on usb...and I had bluetooth...gps, and wifi...plus running some apps and stuff...the battery actually continued to drain I think they have the usb thing as a safety measure...for some reason...I think it's odd...but meh
try a usb cable that has 2 jacks plugs to connect to tyhe computer. These cables are often supplied with external hard drives as they they require more power than can be supplied by just one usb connection.
I was also having the problem of my p-930 discharging while plugged into compute usb jack - even when screen off nad only in charge mode. I have since bought a dual plugged usb cable and it charges now. Although I haven't tried it from a completely discharged state.
my spectrum is the same way.. i can charge it with usb.. but it takes about 15-20 minutes to get enough charge to turn on
