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?

[Q] Rapid Chargers - Not Really Rapid?

i bought that Motorola Rapid Car charger recent and have been using it about a week now. i've noticed that it doesn't seem to charge my Thunderbolt any faster then it did when i was using the Thunderbolt's USB cable with this USB car charger adapter.
so, my question is, why is it called "rapid" if it doesn't charge any faster?
and i suppose secondly, is there an actual microUSB charger that will charge the Thunderbolt faster?
they make one for the iphone that will fully charge it in 30 minutes so i know they are out there.

Maybe you should try this one.

Install the battery monitor widget. Monitor the battery for about 20 minutes while charging. Tell us what the charge current is.
Does the Motorola charger include a cable? If not, you may just have a weak cable. I have seen cheap cables with wire so thin that the charging current is no better then charging off a weak USB port.

My experience has been that the phone typically recognizes car charges as USB charging and uses a different charging profile. My solution to that is use a wall charger through an inverter or a kernel that doesn't use radically different charging profiles for A/C and USB.

No need for that.
Cut a small piece of aluminum foil. Carefully place it where it shorts the two center conductors in the charger. Plug the USB cable into the charger. Make sure the foil stays in place over the two center conductors.
It is now a high rate charger. (assuming it can put out 1 amp.)

The limiting factor is typically the usb cable itself. Most usb cables can't support the 1amp that is provided to it. Since you used the original usb cable that came with the thunderbolt (that's been "shorted" as mentioned above" ) it will be just as fast as the moto car charger. the 1amp charging rate that the moto charger charges at (i have one) and that the original one charges at are already "rapid". if you plugged a normal usb cable from somewhere else into the other usb car charger, it'd be much much slower

The stock charger is what shorts the connections. The cable is NOT shorted on the two inner pins because they are the data connections used for connecting your phone to a computer.

To meet the USB charging spec (which the TB uses), the two inner (data) contacts should be shorted with no more that 200 ohms.
But, the cable can also be an issue for rapid charging. The voltage drop for a 1A/5V source, across only .5 M of 28 gauge copper is ~220 mV. If you use a longer cable, there's more voltage drop. The TB likely current limits itself when the voltage drops below a certain threshold. Best to buy 24 gauge USB cables, if you can, especially if getting longer ones (monoprice has them).

I think its a matter of rated output current. BUT on the other side, the phone must be capable of drawing/using that much current. If the adapter is rated for more current than the phone can charge, the "extra" current wont be supplied.
Initially, Moto's standard car chargers output 5V and up to 550ma max (just like a standard PC USB port) so they didn't charge phones all that fast. Moto then came out with chargers that had higher current output, so they were capable of charging the phones "faster" than the original car chargers (but on par with the home/travel/AC chargers) and called them "rapid car chargers"..
Today, the current output on the Moto SPN5400A car charger is 0-950mA, and I've seen it sometimes referred to as "Rapid Car charger."
But as far as I know, Moto no longer makes/sells the lower current car chargers, and their web site only shows one MicroUSB and one MiniUSB car charger for sale, both of which appear to be of the 0-950mA output variety.

Just because someone makes such a charger for the iPhone, doesn't mean one must exist for the TB, or other phones, does it? I know the iPad uses a 2A charger. What happens if you connect an iPhone to that? will it charge faster? I guess that depends on if the iPhone is capable of drawing more than 1A to charge it.
I've not seen a "home" or AC charger that can charge the TB any faster than the Stock 1A charger. Does such a thing exist?
A proper car charger with 950mA to 1A output should charge the TB at almost exactly the same rate as the stock 1A wall/AC charger.
And btw, the Moto SPN5400A car charger DOES charge my TB in about the same amount of time that it takes me to charge my TB at home with the stock HTC charger. So while its not "rapid" compared to the stock home/travel/AC charger, its "rapid" compared to PC USB Port charging, or a plain lower current car charger.

I made a charger for my motorcycle. I use it as a GPS, screen on MAX, phone active with marginal signal. And I wanted to actually charge the battery at the same time. I did a lot of experimenting with the Thunderbolt. It would not exceed a pull of about 850ma from the supply, even at 5.5 volts. IMHO, you are wasting time looking for any charger over 1 amp.
Also, even with about 850ma in, not much over 500ma is getting to the battery. So a totally dead battery is still going to take between 2 and 3 hours to charge, no matter what charger you have. And twice that long if the charger looks like a PC USB port.

I was asking because of the OP's statement about knowing "they must exist" because they are out there for the iPhone.
I'm perfectly happy with my Moto car charger, and how fast it charges my phones.

USB charging cable

Lately I've noticed something odd. Depending on the USB cable I use the charge rate seems to vary substantially. In fact, in some cases under heavy phone usage, I've seen the battery decrease while on the charger. Now, I know what you're thinking: Some USB cables have the D+/D- pins shorted which switches from USB (500mA) to AC (1A) charging mode. I'm using a really cool CTC-2USB-5V2A charger which seems to show up as AC on all cables (including the ones that barely charge it). The two cables I know are charging it well are the one that came with my HP Touchpad and the one that came with my Kindle Fire HD 7, the ones that didn't have been el-cheapo eBay cables. Since its showing up as AC for all the cables, I'm assuming the only difference can be that the eBay cables use thinner wires which take more voltage drop.
Have people seen this before? Is this the problem? Does anyone know where to get some quality 2 meter / 6 ft cables cheap?

If you want to verify that one cable is allowing more current through than another, I would suggest getting "Battery Monitor Widget" by 3c (in the play store)
Put the apps widget on your screen, plug our phone in and wait for widget to update. Do the same for each cable and compare

CNexus, I am absolutely convinced one is charging faster than another.I was using the battery monitoring that came with the phone (or at least the one in Blazer ROM). You can plug one cable in and update the graph and the slope of the battery state is much higher on one cable than another. I installed battery monitor widget and I do not see anything that shows how much current is going into the phone.
But this really doesn't address the question of why one cable is charging faster than another, is it the wire gauge? Is there something else going on I don't know about?

I can absolutely verify that this is true. It's usually that the pins in the micro sd port are running thin from normal use. Usually normal wear and tear, or possibly the cable has gotten crimped somewhere on it Respectively, the same Non- charging cables are likely to corrupt data transfer as well, making it difficult to do development, or transfer your favorite videos or songs.. Someone recently stole my new cable and all the files I'd transferred to my phone from the computer or vice versa from my older cable were corrupted. Especially ROMS, KERneLS, and Video. This could be a potential huge problem for someone in a sticky situation needing to ODIN, or make an ABD shell connection. I suggest tossing those cables and buying new ones. I know they're expensive, but it might be the difference between having your phone soft bricked till next payday or not.

Timmetal, just to be clear I am comparing multiple identical eBay cables to the Touchpad/Kindle Fire cables.... Sounds like you are saying it is a manufacturing defect in the cables (presumably all of them) that are not necessarily related to the wire gauge. Regardles...
A 6 foot 28 gauge cable would drop about 800+ mV (which is a lot, since a fully charged battery is probably around 4.2V and USB is 5V).
A 6 foot 24 gauge cable would be about 400 mV drop.
A 6 foot 22 gauge cable would probably be 250-300 mV drop.
Monoprice has 3 styles of cable:
1) the 28/28 economy cable (which I presume means 28 gauge on all wires) for 81 cents the
2) the 24/28 cable (presumably 24 gauge on power and ground, and 28 on the others) for $1.40
3) the "premium" cable which they don't give any info on, for $2.96
Newegg has a 22 gauge for $4
Price isn't that big of a deal one 1, but I'll probably buy 10 which starts to make a difference (although prices go down a bit with quantity on all of these). Sounds like the 24/28 Monoprice might be the best bet.

Battery monitor widget is an app, after you download it long press on your home screen > widgets > and there should be one for the "battery monitor widget" app, so basically put the "battery monitor widget" widget on one of your homescreens
And im not saying this is to see whether one is charging more than another, because you can just see that clearly
This is to see how much more it is because this app shows you the mA coming through the cord

The phone software controls the charge rate based on what it thinks it is plugged into. I think it limits its draw to 500ma if it senses a USB port on the other end (since the USB standard limits it to 500ma anyway), it charges at 700ma if it senses a wall-wart type charger. Not sure how it senses the difference, but you will notice on the lock screen it will say either Charging (USB) or Charging (AC).

Sorry if I didn't make this clear, the phone is claiming it is an AC charger in both cases, but one cable versus another makes a big difference in charging speed. Anyway, I ordered 9 of the $1.40 Monoprice cables. We'll see if they work.

Sort of off topic but Interesting. My lock screen just shows charging. USB port on computer, USB cable plugged into wall charger or dedicated 700mah Blackberry wall charger, it makes no distinction as to how it's being charged. It does charge faster using a wall charger obviously but I've never noticed a difference in rate between using different cables.

I'm Having Charging Issues - Are All Micro USB Cables Created Equally?

I bought an OEM Samsung wall charger that charges at 1 Ampere. I started to charge my Zerolemon battery with it yesterday at about 6pm and here it is today and it is only at about 80% charge rate. Something is not right. I contacted the seller and they told me that the charger is from Samsung and it charges at 1 Ampere. It is either the charger is a knock off or my Micro-usb cable that connects into the wall charger is not the right kind.
Are there different variations of micro-usb cables that will work better? Some that allow more current to flow over them than others? My cable says that it is 28awg/2C. I remember when I had a playstation 3 I had problems with syncing the device with my playstation 3 with the USB cables I had bought. After tons of research it was the USB cables that were the issue. They didn't allow enough current to work properly with the PS3. I'm starting to wonder if I'm having the same issue with the Samsung Wall Charger. Is the 28awg wire gauge too thin?

- charger is rated 1amp but usually puts out less depending on the quality and efficiency of it. You won't get the fastest charge with a 1amp psu. Get yourself a cheap 2amp and have plenty of headroom.
- also, if voltage in your wall outlet is low (rare) that would affect psu output.
- yes super thin usb cables can be part of the cause.
- of course, if the cable is meant for PC charging, it will be wired in such a way, to not exceed 450ma (or so) whereas a usb cable or charger that is meant and wired for fast charge, will provide...for me...1150ma (Search/Research my past posts for more detailed info)
- also, most kernels, slow down the charge rate as the batter gets closer to 100% charge.
- a bad battery or custom kernel with bad code, could both affect charging speed.

Length of included Dash Charging cable?

Just placed my order last night.
Losing wireless charging is disappointing, as I grew accustomed to it with my Nexus 6.
Has anyone been able to find the spec for the length of the included cable? Hoping it is decent length, and not as short as the one that came with my N6.

Probably 1m.

Yeah, that's what I was afraid of.

I am going to try my newly acquired aftermarket 2M long USB-C cable this weekend when the OP3 arrives. So far, this cable has worked well with all the other USB-C devices I have tried it with. I will report back with what I find.
Scott-

They've said that you need the official charger and cable to get Dash charging working, which makes sense since it offloads the charging circuitry to the Dash charger.

It makes sense that you'd need to use the included dash charger, but being forced to use a specific cable makes no sense.

Most fast chargers (QC3.0 for example) charge at high voltage and low current. The phone's charging circuitry handles the conversion down to around 4.8V for charging the battery.
Dash charge is at 5V and 4A. The high current causes a large voltage drop. If you pushed 5V/4A through a typical 1m copper cable you would see 3.3V at the phone end which would not be enough to charge the battery.
I'm not sure what they're doing, but they have to be doing something with the cable to maintain a voltage that will charge the battery while pushing 4A across the cable.
