Hi,
Recently I bought the XDA2 backpack. After looking through the manual, there wasn't any instruction on charing the backpack battery. Anyway, I attched to the XDA2 and charged through the cradle, but the backpack battery wouldn't get charged. Any idea what's going on.
Thankz

Did you plug in the power adapter to the cradle? Charging via USB power alone is probably not enough to charge both the XDA II battery and the Backpack battery.
Backpack problems
I got my backpack on Friday 24/3/4, had no problems charging with either USB, or AC Adaptor. What I did have problems with though, was that when I ran the backpack flat (and used my phone battery for the rest of the day), I found that the phone no longer recognised the backpack. NOTHING I could do, would charge the backpack battery, and the phone wouldn't even see it. I even tried charging without the normal battery, and only the backpack. (DON'T DO THIS, I LOST ALL DATA).
I ended up replacing it from my place of purchase. (I'm fortunate to still be in the DOA period)
Charging my XDAII & Backpack via USB, works fine
rahjinoh - Have you let your backpack run completely dry yet? Like, until even your phone battery drop to 25%? Perhaps mine was faulty...
Hi Kev_in_oz,
I had the same problem as you did. The backpack was working fine the first 5 days I had it. On the 6th day, my unit couldn't recognize it, no matter what I do. Had to have my backpack replaced as well. I'm glad it's still under warranty.
The question is, is it just a faulty hardware, or something is wrong with its design - I hope not!
How is your replacement backpack so far?
It's Ok at the moment, but mine only had the problem when I dropped it down to Zero. I called the XDA Help-line (after replacing my battery), but they said that I'm supposed to drain it to zero (they actually said "Charge it for 8 hours, then let both the phone and backpack drain to Zero, then charge it for 8 hours again, and backup often, as you will lose all your data when everything's at Zero").
I'm sacred to do it now, as my shop is out of stock, and if this one dies, I'll be stranded without my compact flash slot. I had to wait 3 months before they got the first unit into Australia, and I'm terrified it will take just as long to re-stock.
Personally I believe it's Faulty Hardware design, ie the Backpack can't be "seen" when it's on zero charge, thus isn't charged...?
Well, When I got my original backpack, it was drained (0%) when I checked it. XDA was able to recognize it.
I'm afraid that it might be something else...I hope that it wont happen again as I have the same situation as you have, no more stock from where I purchased mine. I had to wait about 3 months as well to get my unit...
Here are some of the things I did on the day my XDA lost sight of the backpack:
1. I went to a computer store and was curious with an EagleTec CF Wifi card which I inserted in the backpack. It wasnt plug and play, tried to install the driver but an error occured. On my way back, I noticed backpack couldnt be detected. After several attempts (soft reset, dettached/attach backpack, the unit detected it again).
2. On the way home, I used a brando sync charger with a car adapter...Backpack was fully chargred when I got home. After a while, my unit couldn't see the backpack again, this time it was permanent. The next day, I was able to replace my backpack....
Now I don;t know what really caused the problem...I really hope that it doesn't happen again!!!

Kev, where did you buy it? Retailer? OW?... I try to get one for a while but haven't been lucky so gar...
Regarding you battery problem: I think it could be either a faulty device or the current software doesn't work properly (don't forget that you got your XDA before they even releazed the back pack - they should have a fix for it with the next ROM upgrade)
Besides: is the battery inside the pack user replaceable?
I'm extremly happy with my BackPack, combined with a Dell CF WiFi card it adds a lot more versatility to the XDA II. I LOVE the presentation software, works a treat, particularly like the feature of being able to display the speaker notes on your XDA II but only the slides are projected. Very handy.
I have not run the battery to zero but I would have liked a way to charge the BackPack separate from the XDA II
When I got my backpack it was already left 25%, I just couldn't charge it using both USB and the adapter. I think I got a faulty device. Need to exchange for a new one. Thankz
My Back pack has died AGAIN!!! I'm doing the 8 hour charge (roughly once every 3 days, when my main battery drop to about 20%). Now my phone no longer recognises the backpack. My wifes phone (she got one on the 2nd April) also does not recognise the backpack now, so it's not a handset problem.
Does anyone else have this problem?!?
Doh!
I received my back-pack just today...
...and I'm reading these post just now.
However, it seems my back-pack is only not able to charge its battery.
Because I bought it far far far from here I think not to ship back and change it.
My question: You having problems with back-pack battery charging, did you find something wrong using the CF slot?!?
And...is it still working or You left it on the shelf?!?
Thank You in advance!

Hi all,
The biggest pain I have with my XDA2 is when using TomTom over BT in the E-leads car kit.
Basically with the screen on the car kit does not provide enough power to the xda2.
TomTom does not show the 'no power' icon but the battery level actually goes down and not up!
Eventully the battery goes flat.
My problem is that I can sit quite happily driving along all of a sudden TomTom says gps signal unreliable, basically the phone turns off BT even though it is in use by TomTom!
I'm guessing its something to do with power saving due to the fact the battery level is slowly going down.
I can't find any setting anywhere to say leave BT turned on all the time and not to do any fancy power saving.
Any one else got this problem?
I'm working on building my own higher power psu to feed into the xda2 and bypass the car kit, to hopefully give it anough juice to charge even when in use. Maybe this problem might go away then but I'd thought I'd see if anyone else had been experienceing this???
Cheers all
Kev/.
To be honest I wouldn't use anything other than a genuine XDA 2 car power adaptor. I've got the 02 one (£19.99). I've heard this problem many times using 3rd party power supplies draining the battery rather than charging it.
my tomtom car kit (with ONLY the pda plugged in, i use another adapter for my GPS) charges the batt fine.
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 already used a 600mA charger for the car, heating is the same as with a 1A charger...

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 there forum users...
I have discovered a big issue with my X10i.
When i use the GPS it drain my battery even thoug i bought the S/E car-charger only for that reason (to use the gps in my car)
It seems to me, that the phone SHOULD be able to at least maintain the same amount of "battery left" (not drain the battery any more), when using the GPS with the car charger plugged in, but for some reason even the car-charger don´t give enough power to run the navigation system
Hi.
I recently went a 400km trip with Google Maps Navigation also using the SE Car Charger, but in my case the battery power has risen. Are you using newest Firmware Version?
I have discovered the same thing, using a 3rd party car charger. Sometimes it would just stop charging... It seems to correlate to times where the battery was getting hotter then usual, so maybe its a "feature" of the charging controller to prevent battery from overheating... I was on 020 firmware then, havent tried it since I upgraded...
Same issue as the OP today, with a nokia car charger.
Lost battery power despite being plugged in. Battery also hit 55C, and it's not like I'm in a hot country, I'm in scotland!
Those with success running nav, what model of charger do you use? If it's unknown what's the output in mA?
Mine was doing the same thing (Stops Charging) until I pointed and air conditioning vent up so that it would slightly cool the phone. Then it ran nav and charged slowly the whole time.
It just gets too hot with the screen on fulltime and all of that running.
There is a battery failsafe where it will not charge if the temperature is over a certain degree. If you want ti avoid this, place the phone in a location it can have air from the air conditioner blowing on it.

Hi everyone
Whenever I use my phone in my car as a sat-nav (regular Google Maps), I have it plugged in but even so the battery still drains like mad. I don't use a cigarette lighter adapter, I have the charger cable hard wired to the car using this: http://www.ebay.co.uk/itm/DC-12V-to..._Measurement_Equipment_ET&hash=item3cda83678f
When I installed it I confirmed that it was outputting 5V and the description says it outputs up to 3 amps. That should be enough to keep the phone going right? Though it has 2 USB outs, the charger USB cable is all I have connected to it.
Normally the phone does charge well but when its on sat-nav then it just drains despite being plugged in.
Has anyone else experienced this issue? I am running a ROM which is a few months old, it is the July 1st build of Nexus 5 Experience.
Using right charging cable

All my problems with slow (USB) charging are gone since I've started using "right" charging cable in my car. You may try it by yourself - take original cable from your home to the car and check how it works for you even while GPS is heavily used.
I personally bought this one: (can't post urls in my messages - sorry) 2A-Car-Charger-Coiled-Micro-USB-Cable-4-LG-G3-G-PRO-2-Flex-Lite-G2-mini-Nexus-5-
Search eBay for something similar to this string.
But you may try to look for good one by your self. Hope this could help you...
