I find my Mini charges slower (switched off) when connected to my pc than using the supplied powerpak - would this be correct?
yep..i noticed that too
Yep, but that is with almost al phones charging through usb ports. Each phone I have had before which could charge through usb, charges considerably faster through the wall plug.
Thanks for confirming guys!
charging power of USB
The USB 2.0 of a computer supplies 500 mA @ 5V at most. The HTC power supply is rated 1000 mA @ 5V (read the label).
I had a charger for in the car. It supplied just enough power for lighting the "charging" LED on the phone but didn't charge actually. After a week and a half, the battery was empty...

I'm sorry I did not understand, your battery is holding 10 days?
he charged it in a car, with a car-cable. but the amperage was too low to charge the phone to 100% ; instead it justsupplied just enough energy to keep it alive for 10 days.
but bro: turning phone off for a few hours didn't help?

Hi,
I bought a wall charger for my N1 today. I was searching for one with 1000 mA output so the phone would charge twice as fast, but after having it on for a long time and seeing that it was only 22% charged, I looked at the battery status and it said "USB". I unplugged it, plugged the stock adapter and it said "AC", and started to charge at the usual speed.
Is there a way to have wall chargers that are NOT the ones provided by HTC charge at a normal speed? thanks!
Interesting... it happens the same thing with an iPhone charger, which have the same output characteristics as the stock charger. I never thought looking at the battery status
FWIW, you can easily see if your phone is charging fast or slow by installing the quick system info app (AC=fast, USB=slow).
I'm using the 1000 mA charger with the USB to micro USB cable that came bundled with the phone. Might it be the cable limiting the power?
I've been trying to figure this out too...
I bought a USB car charger to charge my phone in the car whilst driving.
However even with my phone on standby it still loses power.... I don't know whether it's because I'm using the USB cable or the charger is inferior.
It is rated a 1000mA (the charger).
I bought the HTC car charger from expansys.. bit costly at around £20 for a charger but it works perfectly for me. Drove 4 hours with copilot running, and battery remained perfectly charged
As well as the stock charger, I often use a pikie USB charger with a Nokia micro USB cable... phone reports an AC charger in use.
Hey,
Just got my phone 2 days ago. I charged it twice fully so far.
When it was fresh out of the box it only had around half a charge; I let it die fully and then charged it over night when I went to bed.
Next day let it die and then today charged it while I was at work via the USB cable connected to the computer. It took aprox 7 hours to charge from 0 - 100%. This seems freakishly long?!
My old iPhone 3G charged in 2 - 3 hours fully; if not less.
Is this abnormal?
I've never done the charging with the USB connected to the cable. But from reading the forums here, I understand that charging via the computer takes longer as compared to charging via a wall outlet.
Power output from computer is 5v...
Socket (in uk) nearly 50x that.. Other places at least 20x....
Go figure ;-)

That's not how it works...a socket still charges at 5V, but provides higher current.
Mine usually takes about the same amount of time form 0% through USB, but if you do it through the wall charger, it's about half that time...
it's not the voltage but it's the number of milliamps (mA) that determines how fast the phone will charge. USB ports output at most 500 mA while the stock charger outputs 700-750 mA (i can't remember the exact number).
There was me thinking I was clever lol

He's right. The stock charger's output is 700mA. If it were higher, the battery would overheat and could potentially damage it. My macbook's USB port outputs about 325mA, so it should take about half the time on an AC wall plug.
duh, of course. Why didnt I think of that ..
Thanks guys
The mA rating of the charger itself doesn't matter that much. As long it can provide the current (mA) the device needs it'll suffice.
5 volts - 1000 mA charger or a 5 volts 100 000 000 mA charger. They both provide the needed current the device need to draw, and the device will cahrge just as good on the 100 000 000 mA one.
The device has two charging modes: "Slow charge" and "Fast charge"
These two modes are needed due to the USB port standards.
A normal computer USB port can only provide 500 mA at a maximum.
A power-enhanced USB port can provide much more.
Chargers following the microUSB charging standards, are in fact Power-enhanced USB-ports (but with the computer stripped away. )
The device can sense what kind of port it's connected to, depending on how the data-pins in the USB-plug are configured.
If it's a normal USB port, it enters "Slow charge" mode to prevent overloading the USB port (which would cause the USB-port to shut down)
Here the device only draws a limited amount of current due to the limited mA rating of the USB-port.
If it's a Power-enhanced USB port, it enters "Fast charge" mode.
Here the device draw the needed current to charge the battery as fast as safely possible.
See the mA rating as "maximum power available".
A 100 000 000 mA charger wont force the device to charge in 2 seconds, it just have 100 000 000 mA available.
It's up to the devices how much power they need to draw.
There is a "failsafe": If the device cannot draw the current needed for "Fast charge" it will revert back to "Slow charge", and if that's not possible, it simply won't charge at all.
There are two kinds of USB chargers/power supplies:
The "Real deal": It's designed to be a charger and follows the full standards for USB-charging.
The "Dumb one": This one is only designed to be a power supply for "dumb devices", such as USB toys, simple devices, external harddisks etc...
They both look alike, but the difference are one of them are designed do be a charger, the other one a dumb power supply.
Phones usually cannot charge from those "dumb ones" without some modification.
The dumb one can be modified to act as a charger, fooling the device thinking it's a charger:
This modification can be easily done via an adapter or simply modifying the cable itself.
Simply short the Data pins, or sink them to the +/- wires with 10 kOmhs resistors.
Hi all! I have a htc diamond wall charger. As some of you might know, it plugs to a usb cable. Can anyone tell me if i can plug sgs data cable to the diamond's wall charger and charge the SGS?
Yes, you can. But it probably will only charge at a slower rate @ 500mA. Sometimes, when battery level is very low, 500mA probably won't be enough to start the charging. So, don't leve home without the OEM charger.
Yes, you can. I do this using a miniUSB to microUSB adaptor plug that I keep on the end of a USB-A Male to miniUSB cable.
From memory, the HTC charger is rated at 5.0V @ 1.0A, which is greater than the OEM Galaxy one (700mA I think?). I even use the same microUSB plug with the HTC car charger for the Galaxy.
Yes, the stock HTC charger is probably rated at 1A but SGS is very picky about the charger. Unless the charger is properly terminated, the phone will only use regular USB mode (500ma MAX). You can check which mode your phone is charged as by going to Settings->About Phone->Status->Battery Status. If it says "Charging (AC)", it recognizes the charger as AC charger and can charge at higher current (up to 1A). If it says "Charging (PC USB)", it does not recognize the charger as AC charger and charges at 500mA max mode.
Update: my HTC charger from my AT&T Pure (TD2) shows up as AC charger for my SGS. So, it should operate in full 1Amp mode.
At home I have an iPhone 5 charger and a Blackberry Bold 9900 Charger along with a Cooler Master Battery Bank. The out put on the battery bank claimed 5 Volts 2.1 Amps but when hooked up to my HTC One it showed USB Charging. I hooked it up via my iPhone 5 charger which has an output of 5 Volts and 1A and also got USB Charging but when I hooked it up via Blackberry Charger with an output of 5V / 750 mA I got Charging (AC) on my HTC One. Looks like it won't accept any higher power input than what it needs for faster charging.
Picture posted is via Blackberry Charger.
Here is a picture via Cooler Master Battery Bank showing charging (USB)
The maximum current is drawn when the battery is empty. The first phase of charging is constant current, where it will draw up to 1A from AC and 500ma from USB, then moves to constant voltage, where the current will drop off. Your battery is probably too charged to be drawing max current.
HTC phones switch to AC charging when the data pins on the USB are shorted, otherwise it's USB charging.

I need to double check which USB cable I had used. At work now but just saw that the USB cable I had at work was the Blackberry USB Cable and when I hooked that one up with my new HTC ONE I got AC Charging on my HTC ONE. A sales person had told me that the USB cable can make a difference at times. Will try messin around with a few wires along with my Cooler Master Battery Bank to see if the results change.

I find that the charger it came with charges it fastest. The other chargers I have used are my neuxs 4 and gs4.
The phone is looking for a 'short' across the two data wires, I believe. The HTC chargers have this so that the phone knows it's not a USB port that isn't able to deliver the current. I'm surprised the blackberry charger fooled the phone to think it's AC.
Hello XDA!.
I'm new here, but oh well.
My Galaxy S5, Is having charging issues, comes and goes.
Using the Ampere app I'm measuring the charging speed.
Charging with stock AC Charger - 450mA - USB Charging, It won't charge at full speed 1.8 - 2.0A.
Charging with an Aukey Superspeed charger - 1.8A, Charges fine but sometimes stuck at 450mA USB Speed.
Charging with Anker Powercore 20400mAh . 450mA, USB Speed?.
I've switched between three different batteries, all of them does this, sometimes the phone simply tells me that the battery is dead, and it won't charge. ( Note: Phone won't charge but turns on with cable in).
What can I do?, buy a new phone?
Thanks.
