hi everybody!
what I really don't like is, that my MDA Comapct is always charged when I connect it with the usb cable to my computer.
as everybody knows every battery, no matter if li-ion or not, gets worse when charged all the time for short times.
does anybody know if theres a program which deactivates usb charging?
thanks for your help!

Because of that reason i use bluetooth for sincronization, you can do the same. it's a good solution.
You could modify a usb cable to sync only, by removing the power connections I suppose. It could be made switchable also if you are ok with a solder gun.

Hi,
interestingly enough, that is not true for LiIon Batteries. The worst you can do is, always decharge nearly completely and then fully recharge. The method that is recommend for all the 'usual' batteries is no good for LiIOn.
http://en.wikipedia.org/wiki/Li-ion e.g.
The dangers of 'deep' discharging are a lot worse than problems with a high number of recharges. The lifetime of a LiIon is NOT dependent from the numbers of chargiong cycles. And with the non-existing memory effect, there is no reason, not to recharge a LiIOn whenever convenient.
So, to summarize, do not worry about charging the MDA via USB.

Very good link and a very good advice marco99, thx a lot.
As a external powersupply, it says that the capacity is 12000 MAh so enough for 12 charges, or do I make a mistake somewhere?
It seems that a miniUSB connection is suplied whit it so I shouldn't now why it wouldn't do the job and the size is (for me) acceptable with almost 3x3x0,5 inch, I mean for tracking at locations whitout electricity it could keep your GPS going.

USB Charging
Not sure about how many times it would charge your diamond...but it looks like it has a Female USB connector so any USB cable could be plugged into it to charge ANY device...if your device allows USB charging that is.
Best regards

12,000Mah!?!
Doubt it, must have been some serious squashing to get that much juice in there!
My laptop battery is twice the size of that and has 5100Mah capacity. Would be great to be able to charge it from that thing!
Ill just ordered
I just ordered the battery and as soon as it arrives I will write a review of it.
Willem
I don't think it'll work. There were some user reviews on similar charger saying it won't charge their ppc's through USB.

your laptop battery is also higher voltage, probably 12V.
think of the AA-size NiMh cells, the best ones are 1.2V 2800mAh.. two of those aren't close to the size of a laptop battery and yet they have higher mAh.
but you're right, 12000 mAh in that thing is utterly impossible
edit; anyone tried this?
http://www.instructables.com/id/Portable-USB-Charger-Version-2.0/
edit again; this seems more like a real product, but it's larger than the actual diamond is. not too convenient.
http://www.proporta.com/F02/PPF02P05.php?t_id=4125&t_mode=des
late edit; if a computer usb connection is too weak to charge the diamond, shouldn't it be possible to solder a cable that connects the diamond to two usb ports simultaneously?

I have one of those crummy double A chargers from energiser i got from a friend and using the mini usb included with it, the phone does indeed charge but only when its off. When its on the power its using makes the battery pack redundant, but thats for my crappy charger. I think this should work, and if not it would work for another phone or device.

I made a small calculation my 2000MAh is in size 40X35X10mm =14000mm3
The size of the 12000MAh is 74,93X74,93X14,986mm=84138,9704314
84138,9704314/14000=6,0099264593857142857142857142857
6,0099264593857142857142857142857 X 2000MAH (which is the size of my battery)=12019,85291877142857142857142857
Acoording this caluculation it should be physical possible I just don't now how much cell it has and neather or by just doubling the size you can double the capacity aswell.

That's true for another Li-Io-charger which I bought from DealExtreme. From what I can see, they don't check their inventory very thoroughly for function and quality. Most of the stuff is just fine, but there is also some junk - and my Li-Io-charger was among it.
Since they advertise it only for the PSP, I can imagine that it will not offer the high current to charge a working Touch Diamond.
Have fun!

Do you now howmuch is the power use off a PSP?
I do agree with you that not everything is made off gold what they sell at DealExtreme, I also bought already some useless stuff from them but this item should be a verry big mistake from them cause there are rumors at there site about this item, I even doubt about it aswell and thats why I cancelled the order but after I made the calculation I am in doubt again.
I travell a lot and one off the country's which I visit a lot is Brasil and for such a country whit the infrastructure availleble (or just NOT availleble)
If you make a long bus journey or plaintrip (Brasil is at least 12 hours where in you have nothing to do) or even in the bush or just tracking such a item could be ideal.
Willem
After a email with my doubts Deal extreme send me the folowing message, in a previous message Itould them about the doubts and asked them to check or the ordered battery is realy 12000 mAh, they have checek it with the suplyer which confirmed the capacity of the battery, as soon it arives I will post a review of it, which maid take a few days cause I want to test how many times I can charge my phone with both a 2000mAh and the original 900mAh battery.
Dear Willem ,
Thank you for your reply.
Item 19086 was shipped on 12/31/2008 after checking. The supplier informed that it is 12000mAh, we will keep the ticket open, please feel free to send the news once you got it?
Thanks a lot.
________________________________________
Received the battery
Received today the battery but the Mini USB doesn't fit at my Diamond the output is 5V 700mA anyone now or this is enough to use and charge my Diamond at the same time cause if this is possible I will try to make a custom cable.
Someone can tell me aswell which contacts are used to charge a phone on mini USB, as you can see it seems the contacts are about the same there is just a diference at the outside off the connector, the main outside connector is a standard plug but I don't now or there are connectors at the market to make from the standard connection a mini USB
The connector fits at my dock and is able to charge my phone so in case of emergency I can charge the extra battery that way
Here some pictures
http://84.104.255.96/connector/index.html
Well I tested the battery and the outcome is disapointing, could charge my 2000mAh battery once complete so I gues all the critics about it where right, I have contacted Deal Extreem but untill now no answer.
Willem
Anyone nows where to find such a connector?
Its to connect a external battery to my phone.
Thanks in advanced

That would depend what you mean by 'round'
This comes with a round connector.
For 1 thing such a tool could be usefull at least its easy to discover which wire I would need if I would customize a cable by myself
I ment more something as on the image but what I need then is the female

Did you see this? http://cgi.ebay.co.uk/HTC/O2-Touch-...temQQimsxZ20081215?IMSfp=TL081215129003r31462
It has a cable (shown in the pics) similar to what you are looking for.
PS: when you'l finally be able to use your 12000 mhz external battery (hope soon for you), could gently report here? I'm looking forward to buy it too.
Thanks.

I made for the time being a connection by myself whit some cables and I am testing right now, I can tell right now that it’s possible to use my phone during charging with the battery, I have charged the emergency battery now for the second time which takes quite some time to get it full charged, don't now the exact time jet cause I have charged it overnight, but connected it yesterday about 3hour before I went to bed and it still wasn't complete charged this morning it was. I have charged my phone a few times now whit it but this isn't representive yet cause I used the my dock which has 2 lights on it and I kept my phone switched on but could charge it until now this way at least 2 times full whit a 2000mAh battery after that I stopped to do the test without the energy consuming dock and whit the phone switched off. As soon I have the test completed I will write a review about it here.

Can you recommend what you are using? Can it charge fast? I read some chargers can't charge fast.
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.
Dear Sir,
I bought a new HTC Touch pro 2 and I need to have the right advice regarding the first time charging the battery since in the manual theu said 3 hours and one of my friends advised me to leave it on the charges for 8 hours.
my question to the experts is as follows:
1-how many hours you advice to keep the new battery on the charge?
2- For next time charging, do i need to keep it till it lights green ?
3- when I am supposed to re-charge it ( till the battery reaches 0 % or 30% )?
Please advice
Regards,
ZongoL
On my experience no matter if you charge it all night or charge only a few while, after 3 or 4 years you will have to replace your battery
So use it as normal in the way you want and enjoy!
Charging - need some technical help
Hello everybody,
Since the best phone ever died (or better: drown) on me (HTC Universal OFCOURSE!). I had to look for a replacement and TP2 seemed like the best of bad things. LOL!
I noticed that the wall charger had a 5V -1A(mpere) output. My (standard) car charger has a 5V - 0,5 A output. So I got the notice "your current power supply... not enough ...close some ...."
Besides the fact that e.g. tomtom uses more than the charger can give, i was wondering :
is it BAD for my battery charging at 0,5A instead of 1A ?
how much A does a laptop give when charging my TP2 trough USB port?
HAs this got sth to do with the fact that in some programs there is an option like "do not charge while connected to PC?"
I know this is more of an offtopic question, but I hope there is somebody with enough electrical knowledge to help me out!
THX!
