[Epic 4G General] eddieyee:
I have tried multiple chargers rated at various amperages (all the way to 1.2 amps), and it ALL boils down to two things: D+ and D- shorting, and Power Adapter Current capability!. All of my testing was done with a Kill-a-watt power utilization measurement tool.

That being said, you have two requirements to increase your charging capability. First is the obvious to everybody-- buy a higher current power adapter. Anything over 700 amps is not needed, however if they carry it in 1amp, just get it... You may need the current capability in the future for a different phone. I should also note, you do want a little "headroom" so if the device needs 600mah, get a 700 or a bit more.

Most importantly, you need D+ and D- pins shorted. Some Power Adapters have these built in and some (very few) USB cables are built this way. For example, my Nook power adapter has D+ and D- shorted. If your power adapter doesn't have it shorted, you can also modify the USB cable and short the two wires.

Knowing this, the best thing to do is to find a USB adapter that shorts D+ and D- so you can plug it into any USB Power adapter (that supplies 700+ mah). So far I have been on the hunt and have not been able to find this.

Anybody know where you can get something like that? I know we can make our own, but would rather buy the cable and be able to send friends to it as well....
[Epic 4G General] dwallersv:
Some basic electronics 101, gang: For the most part, virtually all consumer electronics are Voltage-controlled, not current-controlled. That means power adapters are constant voltage supplies.

This sort of circuit tries to keep a constant output voltage, with the current varying depending on the load. In simpler terms, the current draw is a function of the load, not the rate capacity of the power supply.

So, it doesn't matter if you attach a 1A rated 5V supply or a 10,000A rated behemoth 5V supply to your phone... the phone -- the load -- determines the current draw, and in the case of the Epic there are two different loads it will present to the supply, depending on whether it thinks it's attached to a USB port or not: 350mA (USB), 650mA (non-USB).

The phone determines whether there is a USB connection or not in a very simple way: It checks the impedance (resistance) across the two usb data pins, DATA+ and DATA-. IF there is no resistance, it assumes the pins are shorted together, and it's attached to a power adapter (by industry convention, nearly all power adapters have these pins shorted together for exactly this reason). Otherwise, it assumes it's attached to a USB port.
[Epic 4G General] dennistpm:
After reading this FAQ (http://xdaforums.com/archive/index.php/t-802711.html) I changed the Operation Value to x2.18 to calculate the current draw correctly.

FYI, I found a micro-USB charge only cable that already has the D pins shorted. It's $12.95 at Seidio. http://www.seidioonline.com/product-p/cbuptr800.htm

I'm guessing it should give you 600 mA when plugged into the car adapter or PC. It will not transfer data.
[Epic 4G General] m5james:
Is this why some wall chargers I use will cause the phone to think it's connected to a PC, meaning when I plug it in, it asks me if I want to mount the phone? I've got like 3 wall chargers floating around the house, and the one I use in the bathroom for some reason always asks me if I want to mount the phone. Does this mean that that single charger is actually charging slower than the other two?

I've also got one USB to MicroUSB cord that doesn't allow me to mount, so does that mean that maybe it's charging faster than the others that do let me mount?

Maybe I have this all backwards, but I figured I'd ask. I'm out of town, and naturally I forgot my wall charger and only have one USB charging cord w/ me and a car charger, so I've got nothing to test against besides my laptop (charging at an average of 168ma) and my car charger (charging at an average of 275ma), which suprised me that the car charger is higher than USB considering what I mentioned above about it dying while streaming and doing navi at the same time once.
[Epic 4G General] muyoso:
Yes. If the phone asks you if you want to mount, it thinks its connected via USB and not via a wall outlet, which means it will only charge at around 350 mA.
[Epic 4G General] m5james:
Interesting...I'll have to see what happens when I get home.
[Epic 4G General] eddieyee:
By the way, that current widget is just plain off.

Don't trust the values it gives out at all... I use a kill-a-watt to measure current draw, and even that multiplier above mentioned doesn't work, as the values from chargewidget are just off.

The kill-a-watt resolution doesn't get as accurate as I'd like, but right now for instance it shows 0.04a current draw for me. CurrentWidget says 273ma.

If I plug in my nook charger, I see 0.06a current draw. Current Widget still says 273ma.
[Epic 4G General] dennistpm:
0.04A = 40 mA so something doesn't look right if the Epic is supposed to be drawing 600 mA from the wall charger. I've got a Kill A Watt also and mine is reading 0.06A. If CurrentWidget is saying 273 mA for your Nook charger and you multiply that by 2.18 you get 595 mA. You need to go into settings and change the Operation Value to 2.18 and Operation Type to *.

I don't know if this setting is correct but I couldn't find any documentation on CurrentWidget but 2.18 is the best factor that I could plug in that calculated both the USB (380 mA) and Wall Charger (600 mA) current accurately, according to the FAQ I posted earlier.
[Epic 4G General] m5james:
I tried those settings and it gave me 5 digit numbers w/ no m or mA lettering. Even if its not an accurate reading, I'm just curious to see the differences between 3 different charging styles and then I'll just be deleting this anyways.
[Epic 4G General] m5james:
I multiplied it by *2.18 and it reading in the 365 range now, which I'm guessing is more accurate.

Long story short, but I'm still out of town and was able to get the wall charger in question that asks me to mount the phone, and it in fact charges at the same rate as being on USB via my laptop. It's a Samsung charger, so I wonder why it acts like this.
[Epic 4G General] Whosdaman:
This is going to cause major battery damage. It will over charge your battery and cause leaks and possibly battery explosions.
[Epic 4G General] m5james:
Who are you replying to?
[Epic 4G General] dennistpm:
There's no way this can happen because the current shuts off when the battery reaches 100%. If you check the log in CurrentWidget it shows the current decreasing as the battery nears 100%. I guess this is the trickle charge phase. At 100% my log showed 0mA.
[Epic 4G General] m5james:
So I've got a question....I've got 4 of these eBay $2.12 chargers that I've put into each vehicle, all of which charge at around 380mah per Current Widget. I used a friends Sprint branded charger yesterday and noticed it charges the same 595 range that my wall chargers do. Is there a way to modify my car chargers to make it charge more...something like the D+ D- (which I don't understand) thing that people have mentioned here? I've taken my current car chargers apart before due to one breaking a connection, so I've got no issue w/ doing it agan to ground together a few pins to gain more charging abilities.
[Epic 4G General] Whosdaman:
If batteries are charged faster then normal then can over hear causing damage to the phone and the battery
[Epic 4G General] m5james:
I'm not trying to over/fast charge the battery, id just like to make my current chargers just as fast as his Sprint branded car charger, which is just as high as a normal wall charger.
[Epic 4G General] digiblur:
The battery won't overcharge no matter what amperage the charger has. You battery in your car puts out a ton of amps, but does you radio burn up? Nope. It only pulls the amperage it needs. As long as you always have more amperage on the source than what the device needs you are good, never good to go the other way.

One other case... I had a device's power brick that was 5VDC 1.5A. I didn't feel like paying for another charger from the manufacturer so I had an older one that was 5VDC 2.5A that fit the device. It's been running fine for 2 years with the higher amperage power supply.
[Epic 4G General] m5james:
Any suggestions for the wiring savy?
[Epic 4G General] pre2epic4g:
I concur... i tested this theory last month as I noticed the phone taking less time to fully charge with my palm pre charger. From a dead battery using a wall outlet my palm pre charger takes 45 minutes less than using the android charger. maybe its the cable as i could never get my phone rooted with the cable that came with my Epic but once i used my palm pre cable it worked immediately. I have experienced the same issue rooting upon other Epic's and even one Evo.
[Epic 4G General] thezero4:
I have huge problems getting my phone to charge while using it as aGPS device. I've tried three different chargers too. Including the one from the sprint store. Everytime lose about ten percent per hour of driving. If someone knows of a charger that works and will charge I would love a link to it. I tried shorting the data connection. But I really suck with these little wires and thick rubber shielding that they have.
[Epic 4G General] Koadic:
Sure, did this myself... This is assuming your using a charger that has a usb port on it and not an integrated charging tip, and is rated appropriately for your phone (1A should be good).

Crack open the part that goes into the lighter/accessory socket (you may need superglue to close this back up). On the part of the charger where the usb port is attached, you will see 4 pins. The 2 outside pins are the + and - voltage connections, and the 2 inside pins are the data pins. You need to take a soldering iron and bridge the connection between the two data pins with a piece of wire or just a glob of solder. Just be sure you dont get solder anywhere else or connect one of the voltage pins to the data pins. Afterwards, you will no longer get a popup asking if you want to mount your phone to your lighter :) and it should charge at the full a/c rate instead of the usb rate.
[Android Software Development] RunTimeWorld:
Since i follw some development groups on google, I found an interesting post, might be worth to share, see the pasted content, credits go to snpe60@gmail.com (whoever that is)

I have created a few plugins that enable quicker start with

development of Android application.

As follows are steps:

1) install "Eclipse IDE for Java Developers" (Helios SR1) from

http://www.eclipse.org/downloads/

2) install the Android ADT installer using the

http://adt-addons.googlecode.com/svn/trunk/installer/com.android.ide.eclipse.installer.update/

update site

It will install ADT features and other required reatures.

When you restart Eclipse, you will get dialog which enable you that

install SDK Tools and Platform SDK easily.

3) If you want to see the source code when debugging an Android

application, install the Android Sources feature using the

http://adt-addons.googlecode.com/svn/trunk/source/com.android.ide.eclipse.source.update/

update site

Note: this plugin is about 100MB size

4) start the "Hello, world" cheat sheet with Help>Android

Development>Hello, world

For more details you can make look at http://code.google.com/p/adt-addons/.
[Defy Themes and Apps] jmoore2:
Has anyone got the new market yet on the defy. Im still waiting lol. And also if it is not ready for the defy yet does anyone know when we shall get it?
[Defy Themes and Apps] dj_destruction:
I cant even get into the market keeps saying server error? any ideas?
[Defy Themes and Apps] lonest4r:
I got it...
[Defy Themes and Apps] jmoore2:
Im having some problems with the market as well. I can access it etc but after i start a download after about 30 seconds i get a notification saying the download was unsuccessful. Googled about and some where it said that it can be due to google talk, Sign out then sign back in then try to download an app, But this failed to work for me though it may work for you. I thought google was maybe starting to block the older version of the market for some reason hence the original question lol.
[Defy Themes and Apps] SlightlyAmused:
I must have just got mine this evening. I JUST looked at my market and there it was looking all sexy!
[Defy Themes and Apps] freemsk1:
Applications - Manage Applications - Market - Uninstall Updates. Then I opened Marked and closed it, whithin 1-2 minutes is was updated
[Defy Themes and Apps] m0nk3e:
Thanx a lot, that worked for me!
[Defy Themes and Apps] DoubleUPi:
Got it since today (18.12)
[Defy Themes and Apps] HEROEdelREVES:
Got it too.
[Defy Themes and Apps] imsuneaik:
i need help , my market changes back to the original one , after closing the application and restarting . Is there any solution to make it permanent
[Defy Themes and Apps] larry_bml:
I have Market 2.2.11 installed from zip file, but doesn't want to work, i mean it say "your application will be downloaded" , after that a short sign of downloading appears and disappear. No error message, no nothing. The application is not downloaded and not installed. I've tried your method but not luck. Any idea what can i do to make Market working?

Thanks.
[Focus General] Alpha0ero:
I paired up my new Focus with my 2010 Acura TL yesterday. As I was driving home from work and talking, the volume from the car's speakers ranged from high to low and eventually dropped the call. I thought it could signal strength related but I had 5 bars so I tried again. This time the call didn't drop but the audio was horrible. Since yesterday I've tried to make calls in several areas of town and the call quality is just not very clear. If I talk and listen normally through the handset, the call quality is good. I have an HD2 that doesn't have this issue so I am wondering if this is Windows 7 related...
[Focus General] tuffluck:
i have a bmw and have experienced similar results at times. though i think my iphone did have its own set of problems sometimes also. i have noticed the increase/decrease in volume before, though. it would be nice to know the source of the problem. likely the phone, not the OS i would think. my phone has never disconnected yet.

i don't make a lot of calls in my bmw really, but i'm getting addicted to the WP7 so i don't really feel like i will be able to trade in and go back to the iphone at this point if the problem is with the focus and not just needing a software update. though it would be nice to have an answer.
[Focus General] gmfeld:
I am also disappointed in the quality of the Bluetooth connection between my Focus and my Acura TL (2009). I had the Focus with the same car, and no problems with the Bluetooth connection. With the Focus, the sound quality is terrible, and I often lose the connection between the Focus and the car. Not a dropped call, this can happen with 5 bars, its the bluetooth connection that drops.

Has anyone been able to improve their bluetooth connection?
[Focus General] genzbenz:
The bluetooth in my 2008 Altima is useless with the Focus. It's all garbled up and just unusable. My original AT&T Tilt was the same way. I think it has something to do with the Bluetooth stacks used in these phones. Sadly, Nissan isn't planning on updating the firmware in their handsfree kit for my car, so I just got a good Blueant headset. Not the ideal solution, but it's better than nothing since I drive a stick!
[Focus General] shigga:
I use mine with a clarion deck. Works and sounds flawless.
[Focus General] stillriza:
I have an aftermarket Sony deck in my car.. Bluetooth call quality is generally good but when it comes to audio streaming..it's hit or miss. I'd say 50% of the time there is always a loud 'hissing' sound in the background which makes the music sound like I was playing it off an old cassette. Other times the music is absolutely crystal clear without any hissing or background noise what so ever..as if I was playing it off a USB drive or CD. I use Slacker to stream music or songs stored on the phone through Zune.. same thing. At times I have to reestablish the Bluetooth connection several times before the hissing disappears.
[Focus General] BigwaveMx:
I use my focus with a Sony BT Stereo and works fine. And all the in/out calls works flawless. Maybe is the BT profile (if the stereo don't have AD2P profile, the phone works in mono instead stereo).
[Focus General] cobalt233:
I have the same problem with the sound volume going up and down. 2006 Range Rover. I finally gave up on using bluetooth in the car. My orevious HTC Focus and my wifes iPhone both work fine in the car
[Focus General] sanibak:
I have the Sony MW600 Stereo BT headset and a 2010 Mazda 3, both work flawlessly
[HD2 Android Q&A, Help & Troubleshooting and Genera] gaby5250:
hello everyone

my phone is HTC HD2

using MDJ froyo HD build

I have problem with big games (that wich come with data)

every time start the game it ask to download data again (which i downladed befor)

where should I put data on SD to work ?

:: for example I download SANDSTORM MODERN COMBAT(1) with all data

i install the game and put the data in folder on SD and put my phone to airplan mode but when i start game it ask me to download data :(((

hope some can help me

and thnx
[HD2 Android Q&A, Help & Troubleshooting and Genera] deadmansink:
I believe you have to save it within the Android folder, not just on the SD card.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Archer:
You shouldn't be putting it anywhere yourself. The game will decide where the data goes, and you should leave it there.

Are you saying that you've moved it and now the game wants to download it again?
[HD2 Android Q&A, Help & Troubleshooting and Genera] JonSolo:
Big games that come with data...hmmm, not from the market. Nor anywhere else. Most every game that you buy from market have to download data later, same with sites like Gameloft...install first then it downloads data after it is installed. Except in one small case that I am aWAREZ of....

You kinda gave it away by mentioning the disabling of the network (airplane mode) so as to bypass the security check on installation. Tsk Tsk.
[Adam General] smedley.jason:
What are the mystery features held within the Adam?
[Adam General] smedley.jason:
HDMI In

Starting off the conversation I would like to state how Rohan has been interested in the graphics processing of the Tegra 2. In one statement he presented as a question he said "If it is capable of capturing 12.2 megapixel pictures from a camera what else could this feature be used for." I say HDMI in with the ability to record your favorite TV shows when it is docked.
[Adam General] Rambler358:
I'm guessing the mystery feature is a kick-stand.
[Adam General] smedley.jason:
I think that would be the most awesome feature. I love the one on my EVO, but i hope they make it dual kickstand so it is more sturdy.
[Adam General] kevin24lg:
A kickstand would truly be epic, but didn't he mention something about a secret sensor on his blog?
[Adam General] Crimton:
yes the adam will not have a kickstand, the secret feature will be some type of sensor. hopefully we find out on saturday
[Adam General] no6969el:
I will be glued to my computer waiting for the video to release.
[Adam General] chowlala:
hot horny chick detector sensor ftw!
[Adam General] chaind:
May be the HDMI Out will give out HDMI Mirroring / eliminating the Desktop in whole loading some linux kernel / OS making it easy for the developers.

No idea.

Crossed fingers :cool:
[Adam General] AnonD:
It's not just one feature. Rohan had mentioned in the blog that the "mystery feature" is actually a number of features "locked" in the tablet right now. They shall be releasing a software update every 15 days that will unlock these features one at a time.

So besides the kick-stand, all the other features here stand a chance ;-)
[Adam General] amir_rafie:
In 19 Dec 2009 , when slashgear wrote an article about Adam for the first time , they said that it has a water sensor !!! :D

​

Also they said that this tablet is sth like this:

​

but in CES 2010 when the notion ink showed the Adam , it totally had a different shape :D

but I think the mystery feature is water sensor! I don`t know it is useful or not....
[Adam General] abrenoch:
My vote goes towards a removable stylus.
[Adam General] Zuber:
I like the secret software features idea. Starting with built in swype.

Anyone know if swype would work on these units ?

Zuber
[Adam General] johnboatcat:
The water sensor

was just probably on a list of parts. It would probably be like the little moisture tabs in the battery compartment of your phone.
[Adam General] Sagro:
As mentioned before, the bonus feature will be something LOCKED in the first time, and unlocked with future updates, and it should be a sensor. No idea which one :D!
[Adam General] CyberGhos:
It could be onetouch breakit, 30 day live, or purposedly unresponsive touch....
[Adam General] mattjacobson:
Wasn't there talk of a back panel touch pad?

I swear I read that somewhere a long while back.

I'm on the fence about whether or not I should have pre-ordered one, but I wanted to wait for reviews first. :/
[Adam General] plvaulter06:
ill bet its NFC. They have been pretty open with saying it will get 2.3
[Adam General] Kangal:
NFC is a gimmick.

What is/does a "Water Sensor"? Is this for people living in deserts? xD

If it came with a dedicated comfy capacitative stylus and hole, it would be sweet.

I dont like kickstands unless they close up to be flush with the device, otherwise it feels weird on the back of the hand.

I don't like the idea of "unlocking" a feature, because I know Notion Ink is dishonest and that they really are lazy/don't have the resources to have everything functional from day 1. They will probably slowly optimise the stacks/drivers and once they are working properly they will "unlock" it in future updates (God knows how long it takes).

But I must commend them for making this seem fun.

For eg/ my SGS I9000 had a GPS unit but it wouldn't work at all, the Froyo update "unlocked" it, but the official Froyo update also gave me more lag, more force closes, and took away multitasking (each app is automatically closed when you hit the Home button!!!!).
[Adam General] nealed:
Not talk or a rumour, this is confirmed. In order to fully view the screen and allow easily selecting links etc. without obstructing the screen with your hand. NOT the mystery feature in any case, but cool, I think
[Adam General] smedley.jason:
Yes their is going to be a track pad on the back. I think you should pre-order the next time it releases, because benchmarks are just off the wall. The track pad is rumored to not be enabled though because "They were not satisfied with it's quality".
[Adam General] twospirits:
You make it sound like you work in their offices and know them very well. dishonest, lazy, Please, do tell us the specifics on how you came up with this. As for unlocking features and taking long for updates, you make it sound like everyone else is quick to update their devices except this company. :rolleyes:

There are two things I've heard and 1: that someone else has a patent out on that sort of rear-end trackpad and is delaying Notion to officially spec it on paper. the other 2: is that they are not happy with the test results and are thus disabling it, until they perfect it (translation, future update)

As for the mystery device..

in one of his blogs he stated: ""For any sneaky fellows looking through the code, here’s a tidbit for you, there’s a very awesome hidden sensor we’re gonna be revealing soon."

Could be a NFC (Near Field Communications) sensor. But he stated that that would probably be in EVE.

If its not a sensor then I personally would like the kickstand. But has anyone seen the recent back of the device?

TS
[Adam General] kapanak:
Well, sadly, Rohan just confirmed with AndroidPolice (interview) that the trackpad will be disabled on the first generation Adam, and will come with later models. Basically, it won't even be there...
[Adam General] toca79:
I may be wrong but i understand he just said that it will be disabled at launch, untill they adress the performance problem.

He didn't mention the second gen adam at all...
