Hi,
I just bought this retractable USB sync cable by Brando (see attachment). The problem is, it doesn't charge. Although the charging indicator LED on my XDA says it's charging, but as I monitor the battery meter, it's still draining. Is it really like this?
it depend on how much amp the usb can give default is 500mA
not sure if thats enough for the pda to be turned on without using more power then it gets
that would explain why it dont charge
try leaving it off while connected and check after awhile

Is there any way to get my X7510 to be more efficient at charging?
It seems recently that even from the straight charger it's taking almost all incoming power to run leaving next to nothing for charging.
USB Sync has always been like this, but straight charge used to be quite quick.
Are you using the original charger that came with it?
I've also found that the Flint is much more fussy about charging than any other device, including the previous X7500. USB charging takes an age, especially if the device is left on. My 'power pack' emergency charger hardly charges it at all, despite being able to fully charge my Advent 4213 netbook. My Diamond's wall socket charger hardly charges it at all, despite being technically the same spec as the Flint's one.
My original charger, and my Brodit car cradle both still charge mine pretty well- the Brodit will charge it up from 50% to 100% in about 1 hour, even with SatNav operating.
With my external power pack, or if I can only access a USB charge, I now use a screen-off application (built into PocketPlus) to keep it turned on, but on a very low battery drain.
Yes, it's the original charger. It appears to have had a knock though, the plug is a bit bent. I wonder if that's damaged something :-/
Can you guys recommend a small portable power recharger that works well with the X7510?
I would be taking a long flight soon and I would like for my X7510 to last the trip.
I can't really suggest anything because neither of my 'emergency packs' work properly with the X7510.
Perhaps you could check with the airline whether they have 'in-seat' charging/power facilities? Some have a powered USB charging socket and some have proprietary connections, but might have a suitable adapter?
Hi,
Can't seem to figure out whats wrong with my i780 so was wondering if anyone here has experienced similar problems.
My i780 don't seem to charge anymore when using the charging plug (plug it in, no charging light or charging symbol.. etc..)
Plug it in through USB, phone charges fine (charging light comes on, charging symbol displayed)
Now, I thought, oh must be the plug, so I tested it using the charging case... charging light comes on battery charges fine!!??
I would just forget about the plug but I can't seem to get a full charge just through USB.
So if my phone charges by USB, plug not working on the phone, but works with the charging case what could be wrong???
Anyone have any suggestions?
my i780 always show charg icon after upgrade...what the probem??????????/
i had the same problem as you. i sorted it out though. Do you mostly charge through the external charger?
i just kept on leaving it on charge for about an hour or so. Soft resetted the phone while on charge and then it worked fine. LED went on and the whole lot.
Try to charge your phone at least once a week with the battery in the phone. I can't prove that charging almost exclusively through the external charger does this but i have a suspicion. That is the only unusual thing about my usage pattern.
Has anyone had the same problem
I'm not sure, but would it be possible for the G1/Android to detect what power source it's plugged into? From what I understand, a lot of wall-warts speak somewhat to the device. If minute differences could be found, they could be "labeled". Applications for this would be power based setting changes. For example, plugged into my computer-> screen on, bedside charger-> backlight off/ringer silent, Car charger-> GPS, bluetooth on, blah blah, etc. Anyone have any thoughts about this?
Sounds like a neat locale plug in if this is possible.
I know devices can tell the difference between a USB plug and an electrical outlet
Not sure about the car charger though.
doesnt the app power manager do the job?? idk about the car charger one tho
Z
The reason I think this may be possible is that I had a RAZR a few phones ago, and it would only work with Motorola power supplies, but my BB pearl I got after it would work with it as well. And if I recall, iPhones require some kind of handshake to work with a usb plug. Just an idea and was wondering about it's plausibility.

I looked at power manager, and it does change settings depending on whether it is plugged in or not. The real point of my inquiry is not whether setting can be changed, but can power sources be ID'd. Setting change is just an application of the information. You could also have it launch an app too if plugged in, IE a navigation or music app starts when plugged into car charger.
Detecting the difference between the USB cable and wall/car charger should be simple enough - only one of those has a computer on the other end, and the phone already detects that. It even shows up in the spare parts app on CyanogenMod as "charging (AC)" and "charging (USB)".
Not sure if there is a way to differentiate between car and wall charger. (Though you could always hack something together using the GPS and define the car charger as "any non-USB charger outside a set location". If you're not travelling much, that is.)
If you use "Spare Parts" and bring up the battery info screen, it will indicate (AC) or (USB) when the phone is charging...
Using the AC charger makes a big difference on these phones. I run Wifi Tether on 3G all day long at work. Using the USB charger, the phone will die. Using AC, it will stay on 100 charge even if I'm streaming music all day...
I think the max output on a USB cable is 0.5 amps. The HTC charger is labeled as max output 1 amp. I'm no electrician, but the AC cable could in fact be twice as good as USB charging.
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).

I was just curious, lol. Would the phone break or something? Thanks.

Oops, wrong section...Sorry! I don't know how to move or delete this. Anyway, my curiosity stays.
I think qi charging overrides USB charging, but it could be the other way around. Either way, the phone knows to deactivate one.
According to the battery monitor, wired charging (USB or A/C) overrides wireless charging. So, if you plug it in, it doesn't matter if you place it on the wireless charger or not.
I seem to recall someone at Google (on one of their product QA's for this phone) that even though it makes logical sense for the AC charger to take precedence (faster, less heat generation) but the QI charger is the one actually doing the charger.
I realize this contradicts what the battery status would indicate, but it is plausible that the indicator does not report it correctly.
Either way, the only time I can really see this being a factor for me even REMOTELY, is in the extremely rare event I have the phone plugged into my computer via USB, and sitting on my qi charger. But that almost never happens, I sync data to/from the phone over wifi just because, well, it's easier. It's not faster, but since it happens automatically it takes less effort.
In that case, I'd actually prefer the qi charger to work, since it's a faster charge than my USB port.
imagine the hilarity if both charging circuits worked though...sounds good in theory but I think we'd all have broken phones
I've plugged in my USB cable (hooked up to my computer via USB 3.0), while my phone was sitting on my Qi charger (nokia, 750mah), and the usb cable takes priority over the charge.
When wireless charging is in effect, you hear the NFC tone from the phone. Also the light on the charger turns on when its charging. It doesn't play when you lay a phone with USB plugged in, and the light doesn't turn on in front of the charger, so.
I'm pretty sure this would disrupt the space-time continuum.

I can confirm that while setting on the wireless charger, the "charging" light is on on the charger, but if I plug the cable in, the light goes out. The wired charger is DEFINITELY overriding the wireless charger.
For people using OTG cables or external storage adapters on the microUSB slot they do require wireless charging to work while being "plugged in".
awesome question...I have a S5, which has a galaxy charging current app
does one exist for the nexus? if so, you could tell by the amps it is charging at
