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?

I'm having real problems with portable chargers for the X7510
I have a U2O 13200 mAh charger for my Advent netbook, which also has a USB output for mobile devices at 5V/ 1000mA, but unless the X7510 is on standby, or in screenoff mode, it won't charge fully and takes an age. Likewise for my Maplin minicharger, though that's no real surprise.
The only reliable way to charge mine without the wall charger, is to plug it into my Brodit active holder in the car! For some reason the X7510 seems to draw more current than USB can supply when turned on- not something I noticed with the X7500.

This looks nice. Sad that it does not work well with the X7510.
Does it maintain the battery level if you have your X7510 turned on while charging?

I wonder if the USB adapter on this link (post #7) can fix your charging problem: http://forum.xda-developers.com/showthread.php?t=387531&highlight=usb+chargers
or how about using the original active sync chord to charge?
I might go for this charger: http://www.tang-shop.com/universal-external-battery-powerbox.html
Then I will also buy the PPC Tech's 5 pin Adaptor: http://www.expansys-usa.com/d.aspx?i=145975
Thanks for that info- may try the adapter. I'd just seen a similar post on Modaco about the Omnia and Diamond CDMA phones and the fast charge/trickle charge problems. 1st I'd heard about the differing pinouts!
I've tried all the different USB cables- the X7510 is only supplied with a standard USB cable (at least mine was) though my Diamond has the enhanced one. Neither makes any difference. My problem is not really that it won't charge from the power pack, but that if left turned on, the power pack stops charging after a time and I have to press the charge button again to restart it.
USB via the PC just about manages to trickle charge it, unless its set to Disk Drive mode, in which case it is faster; screenoff/standby is faster still.

Yes, I'll post my update and review. I'll be ordering them today. Hopefully this will work
Hi all, I travel a lot by train and I am always using my flint to watch videos etc.
I have two Emergency chargers and I manage to use both of them happily,
A couple of things i will note down are,
They both power the device and I cant get a decent charge out of either of them but the flint will drain the external battery first. e.g. If I am watching a video I plug in either of the batteries and the flint will deplete those before it starts using its internal battery.
I have noticed a decreased charging time (Faster Charge) when the phone is in storage drive mode. I have no idea how this would help its just something I have observed while using the chargers.
On the odd occasion the flint will attempt to Sync to the batteries!? Again this is complete madness, the only explanation I can think of is the phone assumes its plugged into my PC.
The chargers i use are,
Emergency Charger
I like this one because it takes standard AA batteries which are available everywhere. It provides about 1 hour to 1 hour 30 minuets of constant power on a Standard Duracell AA.
FreeLoader Solar Charger
This one i bought ages ago the solar panels are not up to scratch so i charge it via USB. It provides 1 hour of constant power.
Hope this helps you out; let me know if you need any other info.

Atomiser
Now I'm interested in this, too. I'm planning on doing a cycle ride from John O'Groats (Nothern tip of the UK) to Land's End (Southern tip) - commonly referred to as a JOGLE.
During my JOGLE I will be using GPSed (www.gpsed.com) to track my progress. This means I'll be using the data connection to upload every five minutes or so, as well as constantly using GPS to log the route.
Needless to say I don't quite expect my battery to last the 6 to 8 hours of cycling I'll be doing every day, so I need to look into some other methods of charging my x7510.
Also, cycling in the UK means that solar chargers are more often than not somewhat less useful than what they'd be in sunny climates, like Turkey.

I believe NeilM's suggestion of U2O 13,200 mAh battery charger is an excellent option for your need.
When I get my charger, I will try and charge without the PPC Tech Adapter and see if it will fast charge or not. If it won't, I will then use the Adapter and see if it works.

I decided to skip this proceedure and use the PPC Tech 5 pin adaptor with the 4400 mAh from Just Mobile. I will then ran a movie in continous loop and see how long it will take for the charger to be depleted.
UPDATE:
I ran a movie in loops with BT headset stereo ON for sound. My X7510 was fully charged with green indicator lights and so is the battery charger. The Just Mobile 4400 mAh Charger lasted 5 hours until my X7510 had to rely on its own battery power.
I also connected the PPC 5 pin USB. Basically my X7510 used up the power of the charger first, as I can see the green indicator light on my X7510 for the full 5 hours.
I would definitely recommend this charger to anyone. It is small, about the size of 2 AA batteries stacked side by side. It is well made and the finish feels like it is coated with rubber to give you a none smudge surface probably to avoid sliding off the table. I give it 10/10.
Excellent news!
Do you think the PPCTechs cable makes a difference? Not got around to trying one yet!

OK, I'll test it too just for you. I will only use the cable provided by the Just Mobile Charger 4400 mAh, since in my first test I already made use of PPC Tech's 5 pin adaptor. I just finished charging my X7510 from the wall outlet so it has its green indicator light on. I am now waiting for the green indicator light to turn back on after attaching the charger so I can start the test again. Will update you guys with the result.
Update:
10 minutes passed and I don't see the green indicator light. I have my X7510 setup so that if it is charging the screen is turned on with full brightness. It makes me think the 5 pin adaptor does make a difference.
30 minutes passed.... all I saw was the orange indicator light (my device is charging). I think it is safe to assume the PPC Tech's 5 pin adaptor DOES WORK. The charger can't keep up with the demand of my device, with just the screen turned on with full brightness.
I will now attach the 5 pin adaptor and wait....it took 15 min for the green indicator light to show.
CONCLUSION: The PPC Tech's 5 pin adaptor does work for fast charging the X7510.
Thats great! <getting credit card out and calling Expansys!>
For reasons unimportant here, I only have an HTC Diamond charger. When I use that with the X7510, it keeps turning the power on (ie it won't charge in standby), so this may be related to the USB config. I'll try the PPC Techs version!

Are you sure you programmed your device to shut off when charging?
Because on mine, I have it setup so that the screen is always on and in full brightness when charging or syncing via cable.

I have experience with a device RELATED to that 5-pin adaptor. It is called "HTC Advantage Lil Sync DUO Pro HandsFree & Charging Adapter" (http://www.ppctechs.com/HTC-Advanta...c-DUO-Pro-HandsFree-Charging-Adapter_1008.htm). I have used these for years with HTC Advantage x7501s. I would have to say they are ALMOST correct when they say:
"In some cases, your HTC Advantage will not charge from an AC/DC adapter or other charging accessory when the battery life is below 30 percent. Our Lil Sync® Duo Pro Adapter will charge your device from a completely drained battery."
I've never had it get that bad, but it can be very slow to charge once it gets below 20%. And using a high-current adapter doesn't help. (A high-voltage one might charge faster. Use at your own risk.) Using the Adapter_1008 with the switch set to F will often get it charging even from a computer's USB port. But not always.
I've only had an Athena 1.5 (Ameo 16GB from T-Mobile UK) for a day, so I have limited info. It does acknowledge it is charging with the switch in either the S or F position, so it is a fair guess that it uses the same pinouts for charging. YMMV.
I have found that the HTC x7501s are just plain weird about recognizing headphones, with or without the adapter. I have built various hypotheses about it, and the machines have disproven every one.
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.
Sent from my Desire HD uing XDA App
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).

Hi,
Today I was using GPS app - HTC Locations. In about 45 minutes battery went down from 100% to 50% (I noticed that using satellite GPS makes the phone very hot) and I decided to connect a charger that I have bought recently - HTC CC-C200 car charger.
The problem was... the battery was still being discharged!
I turned off the nav app and left only basic system apps and the phone was charging only about 5 percent in 30 minutes. Keeping in mind how fast the phone was discharging using navigation, it is simple that the car charger won't do.
Anybody else has this problem? How can I actually use a navigation??
is it the official car charger from t-mobile.
Sent from my HTC Sensation 4G using XDA Premium App
It is original HTC's car charger - CC-C200
One question - can an USB extension cord (plug in to this original HTC's charger and then original HTC USB cable to this cord) decrease the speed of charging?
Car chargers will always charge slower. 12v vs. 110v.

Are u sure that the 110V network adapter, charge the phone with 110 volts ?
The 110V charger:
HTC New Slim Design AC Adapter TC E250 (with EU Plug Unit + micro USB Cable, 5V/1A
and the car charger:
HTC Generic Car Charger with USB/micUSB Cable CC C200 (1A/5V)
have SAME charge power: 1A at 5Vm that is 5W.
The PC USB ports are rated at 500mA, but if u check the port with digital multimeter (cut the cable and put Ampere-meter) u can see that u can drain ~700-800mA , Asus and SuperMicro Motherboard tested from me
@EniHS if u make the lenght of the cable bigger the electrical resistance grow too . I think that 1 meter more wont be such a problem, but if u really wanna check how this will change the power of charge u need to measure it with Ampere-meter
This is an easy one... I try to never get the charger from the store because it (usually) won't put out enough juice to keep up.
I found that if use the same current for charging my ipad, it works much better and can keep up. With that in mind, you can purchase any charger with a 2 Amp output (10 watts) that has a generic USB connector. Try the search "10 watt usb car charger" on Google or Amazon.
Get the free app "juice plotter," which will plot your battery usage and charge. If you're plugged in and the plot is still going down, then the drain is still greater than the charge, and you'll need a better charger. Good luck!

That would be a solution. I'll buy 2A 5V charger. I assume that I should only replace the plug and the USB cable can be left from original HTC car charger?
Isn't it dangerous for the phone to charge by 2A instead of 1A (original charger)? Or the only difference is the charging speed?
Solved!
I did some tests today and discovered that if I charge the phone normally (no program running, GPS off) with HTC car charger WITH extension USB cable... phone was charging 1% in 25 minutes!!! That would be over 40 hours to charge the device from zero to full! I thought I had charger broken, but... I tried with NO EXTENSION CABLE, just the HTC plug and HTC cable, then the phone was charging normally 1% in 2 minutes!
So... the problem are extension cables, but still don't know why...
I noticed this even with wall chargers. Yesterday when I bought my phone, I plugged it in to my old charger & noticed it was charging slow. Once I switched to the charger that came with my Sensation, it charges normally now. I haven't looked at the chargers to compare if something is different but it is very strange
Isn't strange at all, it's essentially that they are not being supplied a great enough charge and so power from the battery is utilised in addition. ideally you want above 700mAh for standard charging/use.
This weekend I went on a trip and decided to try out using my Skyrocket as a GPS navigator using Google Navigation. I had my phone mounted and plugged in the whole time for about a 2 hour trip. The screen was on the whole time usually at high brightness (it would dim every once in a while.) When I removed my phone from the mount I noticed the power was down to the low 60's, which struck me as slightly odd since it was plugged into the charger the whole time. The next day I tried to use it as a GPS system again, but even as it was plugged in, this time I literally saw the battery gauge draining. When I turned off navigation and the screen the phone would finally start charging.
Is this a common thing or is there an issue with my phone or possibly my charger? Does doing all those things really drain the battery faster than it can charge it? One last note is that I was not in an LTE area during this, or at least not the whole time (I only noticed it was LTE at one time during the trip.) When I saw my battery draining in front of me I definitely was not in an LTE area.
Might be your charger. I'm having no problems using it as my primary driving, hiking and general outdoor GPS unit. When on car charger, it's charging faster then it drains.
I believe my charger is an old Motorola car charger that came with my wife's old dumbphone. It's actually not even a Micro-USB charger, but rather a Mini-USB with an adapter.
This may be a dumb question, but the actual charging port shouldn't be the issue right? I'm assuming those are always the same standard.
Check the car charger amperage output. I have an old car charger to USB that only puts out 750mA and another thats puts out 1A. Anything less than 1A with the navigation running (which means the screen and GPS stay on, of course), and it'll still drain the battery (and even at 1A it may still drain).
I've been putting off getting a powerful enough car charger myself. You'll need one that puts out 1-2A I would think. Most of the common ones off the shelf are 1A or less, and I've heard that some chargers reported max output is not as good as reported.

i second this...my phone won't even charge on some wall chargers, unless 700mAh or higher. let alone do any battery heavy functions like GPS. get something with at least 1a output
I'll try swapping the chargers. I have an overpriced AT&T one that I got for free that is collecting dust.
If the charger has 1A output then it should be OK
I'm having the same problem with my Skyrocket and cheapy charger that I bought at Fry's. Use the navigation with screen on and my battery is less than when I plugged it in.
Going to buy this combo 2A and 1A charger.

When I was looking for a more powerful option, I saw that one on Amazon as well. My only hesitation at buying it was why it was so much cheaper than all comparable options at local stores, or even online...I've heard that the cheapie chargers may not actually output what they say...though for $4 plus shipping, I guess it's not much of a gamble. Let us know how it performs!
P.S.-Pulled up the reviews...not too many positive ones (though 1 or 2 were good): http://www.amazon.com/GTMax-2-Port-...iewpoints=1&sortBy=bySubmissionDateDescending
Its actually more than just the charger output that is a problem. If the center two pins on the USB connection aren't shorted, the phone will treat it as a USB connection to a computer, not an AC connection from the wall, and only draw a max 500mah. I had bought a 1amp and 2 amp charger for my car and would get the same results as the 500. I started to think it was my car limiting my output!
But I then found an article detailing this problem that I've since lost the link to, but the method worked. Pop open the charger and solder the 2 middle connectors together and all is good.
I don't know why the charger manufacturers don't know this... Or maybe this phone is doing something new? Maybe someone makes a USB-> micro USB with the center pair shorted in cable?

Just Google "Solder USB Car Charger" and you'll find plenty of tutorials about how to do that. Personally I'd rather just buy one that out of the box works.
Tried out my AT&T charger (which can be found here) and it worked perfectly. Set up the GPS and everything and now it will charge even while doing all that stuff. Thanks for the help
I have the same issue with my SkyRocket. LTE makes no difference. If I'm using Google Navigation or Waze and the Screen is on my charger/phone can't keep up with the battery drain. If I turn the screen off and keep the GPS app running the battery either doesn't drain or doesn't drain as fast.
I've checked my car charger and it's one of those dual usb ones, with a 1 amp port and a 2.1 amp port. It has no indication of which port is which, so I don't know what port I'm using at any particular time. I've tried both and the effects are the same.
Regardless, when the phone is plugged in to that charger the phone reports that it's an AC charger. Supposedly that means I'm getting at least 1 amp, right? So why is 1 amp not enough?
I don't like the car charger you guys suggested because it has the curly cord. I'd rather use a car charger that doesn't come with a cable so I can plug in my own usb cable.
Any suggestions?
