Hi all!
I have used an emergency/travel charger running on four AA batteries for my WinMo devices in the past, like this one:
http://www.kjell.com/?item=31779&path=
(It's in swedish, but you get the idea what id does).
Here is another example of a similar device:
http://www.advancedmp3players.co.uk/shop/product_info.php?products_id=1401
It's very simple and provides a standard USB-port where you can plug in the USB cable and hook it up to your device for charging, but I don't get it to work with the diamond! It works perfect with the Tytn, so the power supplied should be sufficient. Anyone knows if it's some kind of registry setting about PC-connection or something that's stopping the charging?
It would be nice to get it to work since the battery capacity is limited.
Thanks!
Magnus
Solved!
Ok, the issue is solved. It turned out that the external battery supply didn't put out enough current. If I bypass the resistor the Diamond charges.
If anyone else wants a similar solution, which I can recommend, test that the output current is strong enough.
I started using "Battery Monitor Widget" free by 3c
a few days age.
I noticed that the charging current using the Samsung plug in charger was about 300 ma higher than the charging current using other USB chargers. I read on other battery threads that Data + and - are connected on the Samsung charger to prevent the USB screen from appearing. I wanted to know weather the connection of D+ and D- had any thing to do with this so I opened up one of my other USB chargers and soldered the two middle pins (d+and d-) together. After making this change, I got an additional 300ma out of this charger.
According to Battery Monitor Widget, when charging the battery from 50%, the Samsung charger was putting out around 1180ma. Unmodified USB chargers put out about 820ma. The max current output listed on the charger makes no difference in the result.
The charging time from 50% to 100% was reduced by 25% using chargers with d+ and d- connected.
This is actually very interesting. I have been trying to figure out how to make the phones charge faster and have been searching for higher ma chargers. I wonder if there is a way to modify the cable to achve he same results.
I've noticed that sometimes plugging my phone into one charger triggers usb mode but other chargers do not.

Nope not useful at all - nothing new.
1) It's not 300 mA more. CurrentWidget has a 1.83x scale factor. Covered in the thread above. It's 125 mA more.
2) I'm fully aware that shorting D+ and D- together puts you in AC charging mode, in compliance with revision 1.2 of the USB Battery Charging specification. I'm also fully aware that iPad/iPod/iPhone chargers get treated by our phone as a regular USB port and not as an AC charger.
USB charging is 475 mA. AC charging is 600 mA, unless you're running one of my kernels with charginghacks - in which case it can hit 800 mA when the battery is below 4.0 volts.
Right now, I don't need any more data from the Infuse. I need someone with a Captivate or i9000 to run CurrentWidget tests, I'm looking for VERY specific things.

Please don't post in that thread unless you own a Captivate or i9000 and are able to collect the data I'm asking for. It's not a generic battery research thread - I understand a great deal about how our device works and don't need any more data from Infuse owners at this time. What I DO need is more details and testing with the Captivate since I see many people claim they charge significantly faster despite the charge current limit being the same.
Also, if you had read the linked thread you'd see (as I mention in my post above) - this isn't a new discovery.
Settle Down, The AC charger mode is not covered in the Infuse General thread. It is worth mention here to got the word out. No one is trying to take over YOUR battery thread.
Progress?

Hi entropy,
Im a noob to the forum, but have read your other thread that requests info from captivate users. Sorry not a captivate user here as I am a infuse 4g user with the same freaking complaints from everyone else.. slow charge up time, fast discharge.
Just want to know the update of your investigation and if any progress has been made with improving the battery charge/discharge. I ve been able to improve the discharge rate with JuiceDefender and watch the progress with JuicePlotter from the market. But that only controls the discharge and not the important aspects of the battery as you seek.
Also, minor point I noticed, is when there is a difference when charging the phone in plane mode versus Juicedefender running (and w/out it). Would you like some numbers? I realize this might not be new for you considering the info you posted about charge being split depending what the phone is doing. So, it makes sense if its in plane mode it will charge up faster.
not sure if this is just a coincidence, but I did something by accident that has has improved my battery life. After trying many tips and apps like Battery Dr+ and with modest results. I tried charging with the HP touchpad charger that I recently got. It puts out higher voltage than the standard USB AC adapters. To my surprise , my battery charges super quick and holds a charge even better. Again, it could just be nothing, but my Triumph is experiencing extra battery life as well from the touchpads charger. Just thought I'd throw it out to see if anyone has any thoughts on it.
We should ask the mythbusters lol

USB is 5V, so I'd like to know how it is putting out more than that without damaging anything. Also, as I've stated numerous times (does anyone ever read around here?), the amperage output listed on the charger will have almost no effect on how fast the phone charges. The only time it will affect it is if the output amperage is less than what the phone will accept and the charger will limit output, but I doubt any charger with a power output below what the phone will take would be complex enough to do that.
Your phone will detect if you are getting power from a USB port or the stock charger. It will accept higher current with the stock charger. If you are charging from other charger, it will charge slow. To fix that, buy a new and cut open your USB cable. Short the 2 data cable.

The stock charger is rated at 5.0V/1.0A.
What is the HP Touchpad charger rated at?
I too have an HP touchpad and have noticed quicker charge times. Not sure about battery life though since it varies on my use. I cant use my samsung charger to charge the Touchpad, it says its not powerful enough.

from what i read, the HP charger is 5.3/2.0 Amps.
Not really sure why this would make a difference, since usb voltage is standardized and the kernel controls how much amperage goes to the phone. I once thought my Gtab charger did this, but imnuts pointed all the above facts to me.

Please forgive me if this is common knowledge or already in a thread. I've tried searching the forums and can't find anything on it. Does the GS3 (or at least the VZW version) lack a way to monitor the charge amperage? I've been curious to know how well my new car charger is working, yet every app I try (even diving into the logs with aLogcat) reports no data on charge amperage. Is there any way to get this data on the GS3? Thanks!
Maybe CurretWidget from Google Play? It says in the description that it can monitor how many amps the device is giving off or how much its receiving via AC power.

I've tried CurrentWidget and others and they all report "0 mA" no matter what I do, which is why I've even tried looking in the logs. I'm thinking the GS3 doesn't monitor the amps, or at least not conventionally. It seems there must be some way though, because the phone has to know when to charge using USB mode and AC mode (unless it's just checking to see whether it's connected to a computer or not).
Anyone know about this? I've been searching through the forums and all the info I can find about monitoring charge amps is in the forums for other phones. I would like to know what to do to get this data if possible, and if not, to know that. Thanks!
Hello,
I've just got an M9 and am happy with it. Thought I'd make the most of the quick charge tech so I brought a QC2.0 charger from amazon:
An Aukey Quick Charge 2.0 42W 3 Ports USB Desktop Charging Station [sorry, can't post links yet]
Reading the reviews, and also other threads on here, that people with M9's using QC charge very fast but mine just isn't.
Right now it's taken just oven an hour to charge to full from 49%. Nothing like what other people are saying.
I've contacted the supplier of the charger and they've just sent me another one but it's exactly the same. How should I continue testing? How would I determine if it is the Phone?
The only issue I can potentially identify is that after around 75%-80% the rate of charge seems to drastically drop off.
Any insight would be great !

Are you stock? if not what rom and kernel are you using?
regarding the drop off after 80% thats perfectly normal for QC, it will be quite rapid up until about 80+% then sort of trickle.

Pre - 80% its charging about 1%/minute. Which seems much slower than other people describe.

Did it come with a USB cable, and are you using that one? In order to take full advantage of quick charging, heavier gauge and/or short cables are best. And yes, the closer to 100%, the less difference in charging rate.

Hello,
Yes it came with a cable which was high quality, which I'm also using.
I did have a thought if it was because I was charging it with the phone turn on, but just did a test with it turned off and the results were very similar
Are you using the QC 2.0 port? Because that thing has only one.
I'm always using official chargers, same for my M9..works very well.

Hi, Yes using the correct Orange QC port on this charger.
Perhaps you could share what sort of charging times you're getting with your official charger?
Also worth adding there may be an 'offical' HTC charger but all that should matter is if it's Qualcomm QC2 licence device, which it is and is listed on the Qualcomm website
So I'm back to my original question, how can I tell if its the phone?
It would also be good if anyone with an M9 and QC2 could post their charging times
Thanks

Something else to try would be disabling HTC's car app as it causes issues with charging. Open the car app>go to settings>disable all settings.
Go to phone settings>apps>car>uninstall updates>disable.
I use a Choetech 60W Quick Charge 2.0 for mains, and a Choetech 51W Quick Charge 2.0 Car Charger for the car. The car one is ideal because it has a blue LED for normal power which changes to green when it's using Quick Charge, to give you an indicator it's working.
I get between 1% and 2% charge a minute depending on how hot the battery is and what is running (Viper 4.0.1 ROM - Android M). Usually around an hour and half for a full charge.
Yours doesn't seem excessively slow - make sure you try when your battery isn't hot and when no apps are running in the background. Maybe useful to run the Ampere app to see what the current battery drain is before you start... ideally should be 200ma or less.
Drop off after 80% is normal, ~1% every 2 minutes.

I had the same problem initially with my QC2.0 chargers, finally found out the cables(including the one packaged with the charger) were not up to the task........eventually started getting slow charge warnings.
I use these: http://www.amazon.ca/gp/product/B013DOCZAC?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00
Haven't had a problem since
QC is only effective up to 80%, after that it will slow down so as not to cook the battery. This isn't just QC2.0, this is all forms of quick charging. Lithium based batteries must be very carefully charged as overcharging will lead to devices exploding. Just ask the hoverboard manufactures. As such the charge speed slows down after about 80% capacity. To further confuse things, a battery does not have a physical capacity like a gas tank or other physical holding device. Things like load, temperature, and age all change the available capacity. Capacity %, much like signal strength bars, is simply an estimation done with unknown calculations by the phone vendors. If you really want to know what's going on with your battery, you have to get an app like GSam Battery Monitor that will show you the current voltage of the battery and the charge/discharge rate in milliamps.
I'm using the same charger and it charges from 5% to 100 in 1hr and 20mins
