[Q] got a generic charger....it says-5v 500mah,original is 5v 1a(amper)is this ok?

it says- output :5v 500mah
the original says-output:5v 1a(amper i guess)
will this screw up the battery?

chances are no, considering it is half what htc recommends you charge it with, either it will charge it very slowly (half the current of the original) or the voltage wont provide enough to kick the phone into charging mode and nothing will happen (i.e. the charger "wont work")

Thanks for the help

It'll work, but as panyan said, it'll recharge much more inefficiently than with a 1 amp charger.

Actually... It will charge the phone exactly as charging via USB, as USB is limited to 0.5A.

Yep, it will charge your phone just fine @ USB charging speed, I have a similar charger.

And some of you forgot to mention that the phone will struggle when for example you will play games or use gps. Charge will be insufficient and instead charging it will slowly discharge while using it.

Well yes and no, in normal usage it will charge phone, but when you use your phone the way that you would drain the batty in two hours, then it will discharge.

Hey... Yeah if the charger is a car charger then it may not charge fast enough if using GPS software which can drain the battery fast. 1Amp reccomended for faster charging... other than that should charge fine but just slow like USB charging (which has a max of 500mA).
One question guys... I bought a car charger from ebay listed as for HTC phones. It looks like a cheap knock off product with a glowing blue HTC logo when used in the car. The device is rated at 2Amps. Now from what little I know about electronics I've been told that AC/DC Plug packs with more Amps are ok and the device just only uses what it needs. I'm not however familiar whith battery charing when you have a higher rated Amps charger... Would the battery on the phone just be greedy and "ask" for the full 2Amps? Would this then put strain or be dangerous by charging the phone too quickly?
Secondly while we are on the topic of electronics... I'm trying out a super cheap ebay battery supposedly rated at 1600mAH (I know these rating are usually fake). I've noticed the HTC battery is around 4.17V when fully charged. This battery charged up to 4.2V fully charged... Is that dangerous for the device?

2 amp is better, correct me if i am wrong. So the output is 5V and 2A, is that mean the power is 10W every hour ?

2 A charging current (if the phone takes in that much) will damage the battery in a long term use.

It is incredibly unlikely that the phone will discharge the battery faster than it charges unless you're doing something very wrong, e.g. Running a console emulator while downloading a large file over HSDPA with WiFi enabled (but not connected) and using GPS navigation with screen brightness at maximum!
Screen and background services take approx 150mAh, and I doubt radio will take much more than that combined. That puts drain 200mAh less than USB charging, 700mAh less than direct charging.
FYI: There's a spec for USB charging of mobile phones from supported USB ports which can pull up to 1500mA.

Hmm... not sure for Desire HD I haven't tested GPS with SatNav software using current widget... I do know that I'm pulling well over 200mA just with basic use at home with Wi-Fi on and GPS & Bluetooth off and I kill all backround apps. I do know that I've been in the car and seen TomTom app on my friend's jailbroken iPhone 3G (or 3Gs) and with the GPS on and not doing anything intensive... we were actually travelling down a long straight highway, the phone was chewing more battery than the car charger could charge, so he switched off GPS.
Ah also guys no need to worry about the 2Amp charger... It sh*t itself on the 3rd car use and no longer works at all. Junk! I also noticed on the 2nd car trip that opening Android SpareParts the charge is displayed as USB Charging not AC Charging so yeah I believe that the car charger was only a standard USB (max 500mA) power output and not 1Amp let alone 2Amps. Annoying how false advertising or labelling is part and parcel with cheap Chinese products.I was meaning to test the charger's output with Current Widget (which is what I'll do for my next car charger) but the charger crapped out and was useless before I got a chance.
One thing I did notice from looking at a log using Current Widget while charging my phone on the A/C charger in standby, the charge tapers off the power output the more the battery is charged. To get an accurate idea of if the car charger is going to be outputting 1Amp I'd be sure the phone battery is down to 40% (or in the 40s) then with all other stuff switched off I'd run a log on Current Widget and turn the screen off for a few minutes. You should have a reading of around +700 to +800mA if the car charger is rated at 1Amp.
Be wary of the cheap Asian knock of car chargers with the coil spring cord and the HTC logo that lights up blue.... Not worth the 3 or 4 bucks they sell on ebay for.

There's commonly those double USB cables for laptop hard drives so yeah I can see that if the USB ports are actually giving you the full rated maximum of 500mA you can get 1Amp output with this kind of cable but 1500mA?!? The only way I'd see possible for this is either you have a tripple USB cable connected to 3USB ports that are all outputting the full 500mA (and that's if a triple cable even exists or lets say you solder another one onto a double cable) or you have a USB AC/DC charger or some other USB port/hub you've rigged up which provides more than the USB standards of max 500mA per port. How else is this possible?!? Has the max power output of 500mA changed since USB 2.0 standards?

yeah there are usb 2.0 ports with more than 500mA power supply.
some companys give some extra juice to their (or often only one) usb ports.
for example: i've got an Dell Studio XPS 16 Notebook here. it has 3 usb ports, 2 with normal 500mA supply and one with 1A (for charging your phone, etc).

[Q] Can't charge from Computer USB cable

Hey all,
I often charged my g1 through a USB cable from my computer (rather than from the wall). When I do this for the g2x, it doesn't seem to charge. It either retains it's charge, slowly discharges (more slowly than if it wasn't plugged in), or if I am using an intensive app (e.g. pocket legends) it will keep discharging quickly. Is this normal or is this just me/my phone?
I am using the cable that came with the phone that I also use to charge through the wall (so not a cable issue).
Thx

It charges fine through my computer but keep in mind it will be a slower charge on any device. Maybe it's more slow than it should be on yours.

Did you try using other USB ports on your computer?

I've tried multiple ports and multiple computers (not multiple cables cause I only have 1, but the cable does charge through the wall adapter). I've left it plugged in to the computer for the past 2 hours with minimal use (basically just checking battery monitor occasionally) and I am losing ~2% charge an hour (I'll post a screen-cap after a few more hours of "charging").

mine charges.. very slow.

You should never charge your phone from a computer usb cable. There isn't enough amps to charge your phone while it is on and running. If you play games or listen to music while connected and charging from your computer's usb cable you will still run down the battery. The charger that came with the LG G2x is 1Amp or 1000MA! My previous Samsung Galaxy was around 700MA. Best way to charge your phone is to turn it off while it is plugged to the AC adaptor and use a high amp output charger like the stock charger. If you use generic ones with lower amp output like 500Ma, it will take longer.

The chargers for the gs and g2x both have the same amps. And Hz.
Where did you find that info?
Sometimes I still use my gs charger on myg2x. Both charge in the same amount of time.
But if it is true ill stop that right now.

Charger Outputs

I know some people use chargers other than the stock HTC charger...
does using a different charger with lower or higher milliamp ratings make a difference or hurt the battery in any way?

Dont know anything about damage, wouldnt think so.
In my experience, my HTC desire has two modes of charging USB (500mA) or AC (1A).
If the two middle pins of the usb cable are shorted it assumes its connected to an ac charger so it pulls 1A. This is due to the max rating of a pc usb connection being 500mA, so everytime it thinks its connected to a pc it wont draw too much and damage your pc motherboard etc.
Now coming back to your question, some chargers have their pins shorted, some not. Apart from longer charging times, the only real issue is for car chargers, where some poeple have found that if you use one that sets the phone to USB mode, and you are running lots of thing like nav software etc, the battery will still drain even with the charger connected. ie its using more juice than its taking.
Personally I have charged my desire with many USB devices, like ipod chargers, etc etc with no ill effect. I found out thtat my ipod WONT charge from the HTC charger, whereas my phone would happily charge from the apple charger. Prob due to some usual Apple rubbish about who gets the accessory money, so for travelling I just take the Apple charger now.

Both my kid's iPod 3G charge from their Htc chargers just fine so I'm not sure why yours wont. I bought a dock last week for the phone and when I plugged it in I got the screen problem that a lot of others have had where it doesn't respond much. It was like this for a while after too. The charger was some cheap **** 800mA that came with it but I doubt it was just down to mA.

> Both my kid's iPod 3G charge from their Htc chargers just fine so I'm not sure why
> yours wont.
The Problem is with the generation and Software of the Ipod, older ones charge from
normal wall chargers i.e. HTC just fine, but newer ones are more picky. Notices this
myself with my Ipod Nanos...

you should be able to use anything up to 1.5A just fine with a usb port. Just watch for excessive over heating when the phone is on and charging. When its off and the usual over charge protection in many chargers these days they will stop once the charging has finished. I have a bunch of RC lipo batteries and have never had a problem with anything up to 2A+ for ANY battery i have charged no matter the battery makeup.. over this and you can get quick and significant problems...

that doesn't mean the device is not capable... you have 2 ends, the charger/usb port and the phone side.. the charger gives 1A, normal USB gives 0.5A, and only HTC knows what the phone side can take.. but at least 1A

[Q] Can't charge off PC USB?

My Photon Q won't charge off a PC USB port, or my laptop. Is this common? Thanks.

Are you using the usb cable that came with the phone? Reason I ask....I've discovered this phone is extremely picky about the cables you use. So far of the ones I have on hand, I can only consistently charge while in the car using my Belkin usb charging adapter with the Motorola cable that came with the phone. That includes a fairly nice ferrite core 6ft usb cable I got from Monoprice...which it works fine at home on AC, but in the car it stutters back and forth between charging and not charging.

Just today I used a cheap USB cable I bought off of ebay to charge my PQ using my laptop.
Its one of the ones sold as "HTC OEM USB Charger + cable" on ebay for like 3 bucks.
I also charge it at home using a green 3m cable from ebay, also bought for like 3 bucks lol.

Does it require that drivers be installed on the PC to get a charge? I've tried a few cables that I have laying around. I'll see if I can find other cables to try. The weird thing is if the phone is off, and plugged in, the LED lights up green, as if it's charging. But using the same cable, if the phone is on, it won't acknowledge that it is plugged in.

No, I wouldn't think so...
I've been able to charge off of many different USB cables on my Q. Not sure... Only thing it's been picky on so far is the wall wart - cable it hasn't seemed too picky about.

If its an old desktop with USB 1.1 it may not charge, and many laptops won't allow charging via USB if the laptop itself is not plugged into AC. Just a thought.

Very good point ^^^. I've heard some laptops, even when plugged in, still don't provide enough juice to charge (some) devices. Perhaps your laptop is one of these low-power USB port devices.

ive noticed that this phone is picky about what charger you use. i have a hard time charging on my pc as well. and certain micro usb's i have dont seem to charge it well either. needs to be the stock plug it came with.

I've basically given up at this point. Blackberry AC chargers work well for me, so I'll try and track down a few more of them. Otherwise, nothing is consistent. The desktop I've used has a plenty big enough power supply, and it charges my Epic with no problem. My personal laptop and work laptop both charged the Epic, but not the Photon Q. I guess I'll just have to carry around a charger instead of a MicroUSB cable when I'm on the road with my laptop.
Thanks, all.

All,
For what little it's worth, I just noticed that the words "Not Charging" come up on the lock screen whenever I connect to the USB port of my laptop or desktop. So the PQ knows it's plugged in; it just refuses to accept the charge.

Also, whenever the battery completely dies, the phone will start to charge. It will charge for a few minutes until it has enough battery to turn itself on. As soon as it turns on, it stops charging, and a minute later, shuts down because of the dead battery. Then it starts charging again. This basically gives me an endless loop of the phone charging, starting, discharging, and shutting back off. I can't even get it to stay off long enough to get a useful charge without turning on automatically.

Yeah, the only issue I've had with this phone at all is the extreme 'quirkiness' it has in regards to charging on anything other than the stock usb cord & power adapter it plugs into. Even using the Moto vehicle dock for the Q, its completely hit/miss on charging. It will *often* go into that 'Not Charging' state where its kind of keeping sort of a baseline/'stalemate' of the current charge level for me, not really going down but not charging back up either. Not really sure what's up with that. With my vehicle dock for the longest I kept thinking maybe my cig lighter port on my car is bad, but I don't have issues with my radar detector at all.

Had the same problem with the not charging a few days back. I was leaving the phone in Mass Storage mode because just getting it into Mass Storage was a headache originally.
Hooked it up to it's original cable and woke up with 65% battery. Switched from mass storage to charge only and it started charging.
Not sure if it was caused by being in Mass Storage and wouldn't charge but now I put in Charge Only before bed.

It always works (in my experience) with the original cable that comes with it regardless, its anything else where its quirky.

Isn't there a setting in ##3282# that enables and disables USB charging? Y'all have probably thought of this already. Anyways just thought if throw that out there. This is my first android that was not a low usage device. I know very little about it. I seriously think xda should make tee shirts that say "everything I have learned in life I learned from xda".

charging mi4c through pc very slow or not charging at all?

i tried 3 different usb type-c cable including the one that came with the phone and it barely charges through pc or usb. i would plug it in at around 20% to my pc and 30-40mins later its at 20%.......... is this norm for everyone? its kind of frustrating when i do not have charger with me all the time
is it the cable problem? please help me out here

PC USB outlets do not give you enough current to charge today's smartphones. You need to use a wall charger with the right voltage and amp.
Sent from my Mi-4c using xda premium

Ur pc will never charge it as fast as the charger does. However, your motherboard may have a software which speeds up charging. I have a gigabyte mobo and its soft named "on/off charger".

Its pretty much as the others have said. If the phone charges fine from a wall socket, Its most likely a PC problem.
Smart phones need a lot of power to charge them, usually 1+ amp
But, most PC USB ports (USB 2.0) will only give out 0.5 amp, so 'if' they charge it, it will be very slowly.
A PC with a USB 3.0 port should charge it fine, but not as quick as a wall charger, especially if it has a 'Quick Charge' feature.
