I believe the initial question was: will this constant charging thru the USB sync&charge cable harm the battery. I derive from the answers above that it actually is harmful to the battery. And that is exactly my personal experience.
My first Windows OS PDA with a LION battery was the iPAQ 3630 back in 2000. I also believed the PR back then that the LION battery could be charged as much as you wanted. Untill after about 9 months, when a full battery charge lasted no more than 1 hour! Yes, 60 minutes of iPAQ fun and then it was over.
I then got into a similar discussion as we are having now (other forums, XDA Developers didn't exist back then). Nobody knew the correct answer 4.5 years ago, like today still, but the majority believed that constant charging was bad, even with LION batteries.
I then started to discharge the iPAQs battery to 30% (the 'red' area) and then recharge it fully. As soon as the green LED was on remove the iPAQ from the charger immediately. After having done so several times I noticed that the battery would last longer. After some 10-15 times of discharging to 30% + recharging to 100% untill the green LED is on the battery would last 3-4 hours again.
I then switched to the O2 XDA, with which I had the same experience. Keeping the battery topped constantly decreases it's ability to keep a charge. Or maybe it can't be charged as 'deep' anymore, I don't know, anyway the battery will last (a lot) less long.
I now have the QTEK 9090, and I use Bluetooth to sync, so I don't have to use the sync&charge cradle all the time. I still only charge the battery when it is at some 30%. And the battery lasts some 5 hours with brightness set to medium, MP3 playing, web surfing and all that.
But I agree, it is stupid that you have to act like this, that you can't use the cradle all the time. If the batteries weren't so damn expensive I would simply wear them out and replace them. Something I couldn't do BTW with the iPAQ and XDA with their fixed batteries.
BTW I still have the XDA, I use it in my car for navigation (have the original O2 car kit with GPS mouse). It is 3 years old now, still has the original battery and this battery still lasts 3+ hours with backlight on! Which proves my point I believe.
Battery power / GPS
You may have answered a question that i had been pondering for a while, USB charging. The other thing is, you mentioned you use a GPS mouse, was that with an XDA 1? and if so which one? regards rotorjack
XDA I GPS mouse
It's the 'original' XDA I GPS mouse which can be hooked up to the original XDA I car kit, but in fact it is the light blue/cyan coloured Leadtek 9532 GPS Receiver. Works great BTW.
I've had an o2 mini s for about a week now and i'm pleased with it on the whole. My only real concern is battery life. My mini seems to drain much quicker than by xda 2 s which I had before. I seem to drop about 10% in 1 hour 10 mins and that's just a few calls/txts and minimum fiddling.
8:20 100%
9:42 88%
I've dropped all the o2 software and don't have any tricky 3rd party apps installed only;

I've read quite a few posts about battery life being good on this phone but i'm not seeing it. I'm still in my 14 day cooling off period and i'm considering sending it back for a replacement.

Is Wifi off, bluetooth off. Do you check your email every ... minutes over GPRS?...
With email checking every 10 minutes my qtek battery last at least 2 whole days.
wifi/gprs/bluetooth all off - not used today
Just phone today - maybe 12 calls.
Time now 14:21 battery at 61% !
Now i'm worried ......I reckon i'll be down to 30% by this evening.
16:32 - 49%
maybe there are problems with these batteries i had problems with charging the battery it didnt seem to show correct level, sent it back for another unit
17:26 - 38%.
If another goes we'll be up here all day.
My battery life seems to be utter rubbish every time I charge my MDA Vario over the USB link. I can go to bed with 100% battery and find it dead by morning. This has happened two or three times since I bought it on 5th November. Last Saturday morning I had the USB cable connected to download some music to my SD card with 100% charge at 10:00. I played music for about an hour through the supplied headphones and by 13:00 I was down to 50% battery. By that evening I was down to a few %. I've read reviews that you you should squeeze about 10 hours of continuous music from this thing on one full charge so an hour of music and 7 hours of standby/sleep seems pathetic.
If I charge using the mains charger and sync over Bluetooth I get a standby battery life of about 5 days. Obviously that is shortened with use so in practice I am charging it every 2-3 days (no point starting a day with only 20% left!).
I have no idea why USB charging is completely hopeless. I have tried soft resetting or closing all active apps after charging, to make sure ActiveSync isn't actively running and causing a drain (just as you are advised to with a Bluetooth sync) but that seems to make no difference. USB charging is rubbish. Mains charging is the only way to go, IME.

I confirm USB charging IS rubbish. The reason seems to be that the power available out of that conector on a PC is not enough to charge properly... I had the same issue with BA and Himalaya...
Answer: get a USB charger / car charger that can deliver 1A minimum.
BTW I found a craddle for the Wizard in Dubai @ Plugins. It comes with USB port/cable + power adapter. Works like a charme.

My C500 Did that when I had it Plugged in the Front USB ports on my case, I normaly had it plugged in to the onboard USB at the back of my pc with a usb ext cable so I could have it on my desk but I went off to a lan party and when I plugged everything back in I put my USB cable to front usb port and found it was Discharging my Battery instead of charging it, got my usb in Back port all is fine again now
Maybe you have yours in to the front USB port or non onboard port?
I use a laptop, which only has two USB 1.1 ports but they each supply enough juice to power a USB ADSL modem (not that I'm using one of those these days), which is more than some PCs will manage and also my USB hard drive, which my Shuttle won't. So there is no lack of power from the USB ports on the laptop.
Of course, the USB spec only permits a maximum current demand of 500mA so any equpiment expecting more should not be using USB for its power supply. In any event, the phone does charge from the USB ports, albeit very slowly, but eventually the orange charge light does go green. So my situation is not one of discharging instead of charging.
I've just swapped my ROM from Vario to k-jam so I'll see if that makes any difference to the performance. I know it's given me 802.11g, which was missing before.
I had an M500 briefly (Magician) on Orange that had very poor battery life, it was one of the reasons I ebayed it, gave the contract sim to my wife and started a cheaper better value T-Mobile account with an MDA Compact, which
had better battery life. Typically overnight after a full charge the Orange unit went down to 75% and the T-Mobile one was at about 98% on standby.
My Vario I have now, my other T-Mobile account has very good battery life and charges very well off USB. If I sync it in the morning whilst reading my emails and stuff, let it charge USb for about 25 mins, it'll be full and by the night it will have dropped down to about 80%. This is with about 30 mins of calls, about seven or eight emails sent/received and maybe 15 mins with WIFI on.

I can't remember for sure where I got the k-jam ROM ( I think someone saved a copy somewhere) but try here - ftp://ftp.clubimate.com/ - and then save file K-JAM_WWE_1010903_106_10110_ship.exe
That is a self installing upgrade that includes the whole k-jam ROM and k-jam extended ROM files.
I don't know where to get a Vario ROM from. I did back up my own copy (I hope) but the method is a bit whacky and as I only have a 1GB mini-SD card my ROM backup image is 1GB because the only way to secure the image is to dump the whole card to a file.
Before you go playing around do make sure you have your own backup of the ROM or if not the whole thing then the Vario extended ROM files at least. I'm using the k-jam ROM with the Vario Extended ROM.

Hi,
Is there any way to disable USB charging? I didn't connect USB very often since it will charge automatically and I don't like the battery be charged very often. It might kill battery soon. I like to sync with bluetooth; however it is much slower than USB. It's amazing if there is any tool to disable USB charging. Because it will sync fast and will not hurt the battery. Thanks for the suggestions in advance.
Cheers!

You are thinking of older batteries such as Nicads. Topping up often does not hurt Lithium batteries, in fact it's better for them. Their main enemies are deep discharge and heat - and that's exactly what you're subjecting it to by letting it run flat, then charging for hours to get it back to max.

Dear Ineedtoys,
Thanks for the reply. I understand that there is no so called "memory effect" on Lithium battery; however when I checked the battery spec, I always found that there is a "charging cycle limitation". For example, a specific battery claimed that it can be rechaged 10,000 times, then very USB charging will be counted also. It will reach 10,000 times faster. This is my concern. I don't know if this is right or wrong. Can somebody help to clarify this?

That's true. It's the same with Notebooks. The more you charge it, while it's in use, the faster the battery gets "killed"!

Answer my own question.
I am quite sure that the USB charging can be disabled since I used to see the config on a HP device. I also believed that this can be done by 'registry' since it is Windows tradition. I finally found it after a short study. Please go to
HKLM\Drivers\BuiltIn\usbfndrv
and change the
EnableUsbCharging to '0'
then
soft reset => Bingo.
Hope it helps.

Happens to me ocasionally.
Try a softreset and it will charge again.
Happens to me all the time...
Can it be connected to the fact that some applications crash and leave the system unstable ?
I did soft and hard reset, but it won't charge. Now the phone is dead, i am in the process of arranging funeral with HTC. I email HTC, have not heard from them yet.
May your P3600 rest in peace...and be quickly replaced (maybe only the battery pack...)
My phone is acting very weird too. I charged it up, left it overnight. Turned it on in the morning, it was at 90%, after about 3 minutes of wifi, it was at 80%.
Charing - need 500mah
Make sure that you're using the right charger - I was using accessories from my Dopod 818 Pro - the P3600 would say it was charing, but wasn't actually -because we need a 500mah instead of 250mah (or some such).

I've the same problem... help!!!!!!!
Did anyone get anywhere with this? Been a while and no updates.
My GF uses my old Orange SPV M700 as a GPS in the car, and plays solitaire.
It started to drain really quickly then it refused to charge at all.
I figured the battery had died, so bought a cheap compatible to check it was that.
The cheap compatible came 80% charged, but after two hours of charging, while switched on, battery was showing 70%
I've tried both the original HTC charger and the motorola charger that came with my Bluetooth headset.
Neither seem to work, does it sound like a soft reset might help, or does it sound like the phone is kippered.
I'm not an Orange customer any more (They wouldn't do me a good deal on an Omnia), and it is only as a SatNav/PDA rather than phone, so while it would be no mad loss if is dead, SWMBOd doesn't want to spend out on anything to replace it.
I problem with mine was the mainboard, and it had to be replaced.
If yours still has warranty, deliver it to a repair center.
If not, you have to find a way to charge the battery on another device...

I guess I'm looking for an external battery cradle and then and keeping a spare battery charged.
I think the phone is nearly 2 years old and out of contract
Just a quick update.
Both the motorola and htc USB chargers I have are both full 550miliamp usb chargers.
When plugged in the led goes from solid red, to flashing orange, temporarily to solid orange then a low battery warning, might be fine for 5 minutes or half an hour, then cycles back to solid red and arround again.
Hi everybody!
Could someone having the HD2 answer these questions:
While using the device's GPS over longer time (>1 hour), does the device get as hot as the HTC Touch Diamond? I'm asking that question, because on Diamond after some hours of using the GPS (charging cable in car plugged), the device gets so hot, that the battery doesn't charge any longer. And suddenly your device gets off, although its plugged for charging through cigarrete lighter.
Are there lag problems like with the HTC touch diamond?
Thanks for your replies!
Chris
GPS is one of my primary uses for my smartphones. Over the past 2 years, I have used a Diamond, Diamond 2 and now the HD2. My main GPS software is GMXT.
Yes, in the case of the Diamond, overheating was an issue with extended GPS use. It was significantly better in the case of TD2. Although I have not had the opportunity to use the HD2 on GPS for extended periods, I would guess it would be better than the TD2 - in terms of heat. I think it is a simple case of better dissipation of heat - since the body surface area have gone significantly larger from Diamond, to TD2, to HD2.
In terms of lag, I believe all smartphones will have some form of GPS lag, given its in-built GPSr. However I`m glad to say that the HD2 is extremely fast in getting a sat lock; much faster than the other 2 phones. And a 4.3" screen? It`s very legible when mounted in your car.
Yeah I used GMXT on my nokia 5800 and now on HD2 and for me HD2 is the best phone for gps because of the large screen, good gps processor and it has quickgps. Gmxt on HD2 displays position very accurately during navigation. A little heat issues but none so severe like the diamond.
I was using Garmin mobile XT on HTC Touch HD. It overheated it so much that the screen stopped responding. I had to be serviced afterwards.
HD 2 moderately heats, (but no problem at all) I guess the stronger processor has to do with it.
Something to consider:
The HTC car charger used for the older phones, with mini USB, had an output rating of 2A. While the newer HTC charger for the HD2, with micro USB, has an output rating of 1A.
Thanks for your replies!
So as far as i understood it correct, it is possible to use GPS with the HD2 endless while charger cable is connected in the car?

I don't understand the logic. HD2 has a 1GH processor, while the HD has only 500Mh (half of the HD2) -> HD2 should get much hotter. But as far as i understood now, thats not case...
I'm pretty sure the heat has much more to do with the battery being constantly charged than with cpu usage...I guess a way to find out would be to use the GPS for one hour without charging (provided that the battery doesn't get drained before the hour is up
and then again one hour with the battery being charged and compare heat.
OK, I try to explain the known situation of my/the HTC Touch Diamond:
Using GPS (with IGO) about maximally one hour ist possible. Device gets verry hot, but thats no problem. But using GPS for a longer time (more than one hour, what's not verry unusual) forces you to charge the battery. Normally you won't start plugging the charging cable while driving. So i plug it in before my drive. Normally you would expect, that in that case the battery never gets empty, because it's permanently charging (for examle like a notebook, which's battery is in and is connected to a power source). But the problem is, that after some time the device gets so hot, that the emergency mechanism of the battery stops charging to prevent battery damage (or even explosion). The reason why the battery of the Touch Diamond gets so hot is, that the Processor is directly above the battery.

You're right charging heats the battery up. In combination with a already heated battery through the processor and considering that in summer the temperature can be high and even more heating up the battery by charging... after some time the mentioned battery protection mechanism prevents further charging and after some time the device gets off because there is no more power in the battery although it's connected to a power source...
Because of this issue and under consideration that i'm driving a lot and neet a Mobile GPS device which i can use even for 24 hours, i'm thinking about buying the HTC HD2. Therefore i need to know if the device gets so hot, that the battery stops charging after some time by using the GPS?
Can somebody definetly acknowledge or deny this?
Well, I have had no problems so far relating to heat. I have had problems with current consumption - I have a 500mA rated charger/fm transmitter... was fine with my old Mio, but after ~2min of iGo8 usage, HD2 warns me charging voltage is too low (sure, if too much current is drawn, the RC oscillator of the DC voltage regulation circuit gets out of proper operation). Use a decent charger and you won't have problems.
I was running the HD2 with Glympse for around 7 hours this past Wednesday and it was working perfectly the whole time. It was plugged into the charger constantly and while the device was warm it was no more warm than after a prolonged webbrowsing or gaming session.
Could be that using Co-Pilot or something similar would stress the CPU more than Glympse did but I doubt we would run into any issues of overheating either way.
IGO and Battery charge
1. If you use the IGO when the battery was fully charged before (green light) the HTC will work without any problems.
2. If you direct your aircondition to windshield and cool the HTC it will work fine.
3. I have TYTN II and HD2 and both off them have the same problem with battery charging when using IGO (without a work arround that I described above)
I used my HD2 with IGO8 constantly for 3hrs whilst on a long drive. I had it plugged in with charger the whole time. Whilst it worked fine for the journey, it did get incredibly hot, almost too hot to touch! and when I closed IGO8 the phone was very unresponsive and lagging constantly even though nothing was running, so I ended up switching it off for a few mins to cool down. Worked fine on restart.
Using GPS causes freeze
I am now using energy ROM
radio 2.07.50_2
everytime i use GPS, the device just freeze and the only way to restart is to take out the battery, if it did not freeze, I cannot lock up on any satellites, problem still present after flashing another ROM/Radio/HardReset
any solutions?
hd2
same story.. before HD2 I've had a Diamond that after half hour of charging + GPS it was very hot and it wouldn't charge. On Leo I've noticed that if it's charged 50% and I am plugin to the car charger it still gets hot , I charge it for about 1 hour (trip duration) and after 1 second I'm plugin it out, the battery drops from 100% to 83%.
Hi,
I have a navigation software on my x10. everything works fine but it seems that this programm needs so much battery that the charger can´t charger the battery.
With navigation turned on and charging the battery is still getting lower and lower.
I have a self build car charger in my car with 1000mA but it seems, that it´s not enough.
Have you any suggestions, how to solve the problem? Is there an app to change the cpu usage for the navigation to e.g. 60% instead of 100%? Or is this only possible with rooted phones?
Thanks.
Same Problem over here.
My only solution --> 2G instead of 3G and turning off W-Lan.
In that way (with GPS and Bluetooth active), the phone at least charges very slowly and doesn't drain the battery.
I had turned WLAN, BT, 3G off. But my battery was still not loading... Maybe I have to switch from 100% Screen brightness to automatic. I will try it the next time...

But the charging symbol shows up?
Did you shorten the Data+ and Data- Lines on your selfmade car charger?
I guess, you build it, like i did:
I took a 12V cigarette lighter to USB adapter.
Then I broke that thing apart and soldered a (micro) USB cable directly do the USB jack.
To make it working, I had to shorten the inner two lines.
Otherwise, the phone didn't charge at all.
Then I glued / taped / bubblegummed the whole thing an threw it behind my radio
Or did you build an other solution?
I build it myself, not broken a charger, and yes, it´s working (data is shorten), but it´s not enough to load the battery during navigation. If I turn navigation off, my battery is charging as usual.

Nice one
Uhm.. what about rising mA a little further?
I've no clue what max. should be.
Probably you know?
I've also seen USB Chargers with 1500mA.
But I dunno, if its a good idea.
Phone + Battery would also heat up a little further...
Another Idea:
Maybe there is a couple of Apps running at full load in the background?
Take a look around in this forum.
Especially at the "helix launcher" and the "battery life issues" threads.
You can also download the App "SystemPanelLite".
With that one you can search and monitor the running Apps and their CPU consumption and so on.
With "Task Manger" (the one made by Rhythm Software) you can set up a auto kill rule.
Hope, that helps...
I have also tried to charge my phone with my car charger left from Omnia HD and the phone is not charging ??? HTC Desire is charging but X10 is not. Can someone tell me what could be the problem ??
Tnx
@damirbusic
The Problem is, that the two Data Pins (2 & 3 - the two middle ones)) must be shorten. Then the X10 is loading...
@McKebapp
I´m tried it with helix launcher and have some applications auto killed and all tasks closed. But it's still not enough.
It´s possible to charge the Li-Ion Batteries with 1500 mA. That will be my last solution. Don´t want to charge it with 1500mA due to overheating, specially in the summertime...
I don't have this issue at all, weird

@UserX10:
Uhm... that is strange after all...
Which Navi-SW do u use?
I use "Sygic" for onboard navigation.
Normaly I use Sygic, too.
I tried Navigon, too, but the same result.
Both Apps draining the battery more then the charger is loading...

Which temperatures do you have to deal with?
My last Idea: Maybe some overheat protection, that limits the charging rate?
By my one is the problem defently the temparatur... when i hold me phone in to the airstream from the aircooling then does the phone charging works. If i let the phone just on the right side of me on seat the it doesnt charged. But the symbol on the phone say the is currently charging... with the tool batterygraph can i see, thats isnt true...
aso i can reconized that the phone is hot.. realy hot.. extremly when the sun does shine on the phone.. the only solution is for me, to hold the phone from time to time at the airstream or i let the phone down in to the footweel, where does the sun not shine and a airstream flow around...
The akku is the warmest thing. without the cover, it works better.. i thnk the akku has around 45°... when is hot..
tested with navigon..
Hm... that´s possible. I will try it the next time with holding it in the airstream... Maybe that´s the solution.
I've got an windshield holder (dunno the correct English word).
While I'm driving open with my convertible, I set the airstream to the windshield (demister setting, but without heat), to cool the Phone a little down.
(If the Car is closed, I usually drive with activated A/C at 19°C - 23°C depending on my mood and the frozen girl on my side )
My Phone never exceeded 40°C.
So, this really may be the solution.
BY shorten the middle 2 pins... do you mean "short circuit" by joining the pins together in some way.
I have the same issue - I have the car charger from my old samsung omnia but it doesn't charge the phone and using any navigation software drains the battery very quickly
Jepp, short circuit the both two middle pins, then it will work.
For information: I tested today the charging with power supply.
780 mA is the maximum what the X10 takes. Tested with empty Battery (in Idle Mode and Apps running + WLAN + BT + GPS). Same result.
So a 1000 mA charger is fully sufficient.

i had bought an FM transmitter for the iphone for like 10bucks... the charger is USB so i just use the sony's charger cable and plug it in and it works great for me when i use NAV....no problems here

Thanks for sharing your knowledge.
Great work!
What's your opinion about your battery drainage?
Do you really think that the phone, running at full load, will suck more than 780mA to prevent charging?
Or is it really an overheating prevention?
Something I realized today:
I drove around for about an hour today.
We had 31,5°C today.
The phone was placed in its windscreen holder directly facing with its backside to the sun.
I drove with closed top A/C at 23°C.
At the end, when I was at home, the App "TempMonitor" showed me 56°C at the battery, that still was charging.
On weekend I'll try pushing the limits a little higher.
Empty battery + Navigation + open top without any A/C.
I hope my phone doesn't melt away
