[Q] Using the Transformer as an external power soure for smartphones - Eee Pad Transformer Q&A, Help & Troubleshooting

Hey guys,
messing arond with my new transformer at the moment. Keyboard delay and power drain on the dock suck, but the overall performance and usability are more than enough to let it stay.
Next week i am going to a small local festial, the wacken open air, and i am currently thinking about using my transformer as an external battery for my iphone. It should at least be able to charge my phone for two more times, so i can use 3g and the cam the whole festival long instead of killing those features for sqeazing out the battery up to 4 days.
I tried charging it at home, but at the moment the display turns off, the Iphone stops charging.
I could start playing music on the tab to keep it from going into standby, but that feels like cheating
Is there any way to just activate one (or all) usb-ports without turning on the display or even better: without turning on the whole OS?
Thanks in advance and sorry for my bad english.

most festivals have cellphone charching stations

If you really must charge your phone with the dock, I'd turn off the auto brightness on the screen and turn it all the way down, then set the screen sleep to "never".

I dont know of any method of doing this, but I would be interested in one.

XDA II ALWAYS think it's charging

My XDA II suddenly decided to think it's always charging, EVEN when it's not in the cardle. I don't know why. The upper right corner is always yellow (not flashing). The backlight brightness can only be controlled by the 'On Power' slider. Simply, it thinks it is in the cradle. No matter how I try, be it soft or hard reset, it's the same. In this siutaution, the battery drains VERY VERY QUICKLY.
In fact, this is the 3rd time I experience this. For the previous 2 occasions, I send it back to service centre and they change a new unit for me under warranty. But it's just 5 months and it has already happened for 3 times! It's hassle and I am thinking what I can do after warranty period.
Am I being alone and anyone else has experienced the same situation? Any means I can solve it by myself? Thanks a lot.
I have same help me now
I think this is from using the cradle, for some reason it distorts the pins in the phone and causes a short between pins. I found that using a usb cable makes this less likely to happen.
hm
this is happening to me too
i had to buy a new xda 2 .... i still have the old one , if anyone knows how to fix this i would apreciate it very much. ...
it is the same story, the led is always on, it always says charning even when is not... and the battery only stays charged for 3-4 hours.
I´ve the same problem since yesterday with my T-Mobile MDA², it´s Rom Version: 1.72.01GER (6 months in use without problems), Rom Date 03/16/04, Radio 1.17.00, Protocol 1337.28, ExtRom 1.72.170
The yellow light is always on and the batterie runs very fast out of energy (1-2 hours) and it´s always says charging and think it´s connected to AC power...
Possible fix to "always charging" problem
:idea: I got the same problem yesterday but I think I fixed it. (long rant)
By coincidence I was just finishing up after an upgrade to WM5 with Ramdisk when it happened. Of cource I suspected the upgrade to be the problem.
However, I remembered that I had gotten some snow onto the PDA exiting my car some hours previously, and started to suspect that this had created a short in the system somewhere.
Looking into the charge plug hole I could see that half og the bottom of the hole was covered with some light gray stuff. I used a thoothpick to gently scrape on it and lo and behold a big (relatively) wad of pocket lint came out. It had obviously become wet from the snow and created a short.
Everything works just like normal now. Charge stays fine (especially with my new 1700mAh eBay battery, recomended)
I have not had the problem return after the "fix". Fingers crossed.
I don't think everyone has exactly the same problem but I suspect it is caused by a slight short in the plug area in most cases.
Good luck!
In relation to this, when I sync my XDA II to my PC via the cradle, the phone automatically charges (even without the power supply). Is there a way to disable this charging feature? Cause the battery life will be shortened if charging happens when the battery is not drained first.
Thanks

My 2i does this as well, from what I have read this will not damage the battery. LiOn batteries prefer to be recharged before they get fully drained, in fact they like to be topped up rather then ran flat then fully charged. This is only going by what I have read on the internet, but it was on several differnt sites so I have no reason to think the info is duff.
Tx a lot for the confortable info.
@threadstarter:
the warranty should begin again if you receive a new device!
the warranty is on the device, not on the contract you have!
if you continue that way you should have a new one every half year ;-)

captivate vibrate when fully charged

another great feature. especially if that pesky full nights sleep is bothering you. Samsung are you just testing us?
Does anyone have a solution to this?
Mine doesn't, I don't have haptic feedback on. I wonder if that is why?
Sent from my SAMSUNG-SGH-I897 using XDA App
I didn't notice the vibrate, but...
My Captivate hangs on its charging cord from a low outlet, and I keep it in my bedroom. At about 3AM, I experienced what it would be like to have an AMOLED night-light.
(When it finished charging, it turned its screen on to tell me and the screen was bright enough to light up the entire room and wake me from a relatively deep sleep.)
I've had it charging beside me and knowing the phone is off you aren't expecting anything from it....scared the sh*t outta me twice now,lol.
When the captivate is fully charged does it have a popup that asks you to remove it from the charger along with the alert?

yep... is there a way to disable this?
I am working on a way for the vibrant and just wanted to see if the captivate was the same. Once I figure it out more it should be able to be made for both. Here is the link to my alpha tests. You can try it if you like but I make no guarantees as to how it will affect the captivate. Make sure you have a nandroid backup if you do try it, also let me know what happens. http://forum.xda-developers.com/showthread.php?t=748400
Thanks I'll wait until you get it QA'd.
BTW I figured out a (crappy) compromise, I use CT Scheduler from Market to turn phone off after 11PM. Free app. Not because I'm cheap but I have been spending quite a bit of money on pay apps lately and I like to try things different from the herd so not going with locale.
But anyway, this is a total fail workaround because it would be ideal to have the phone stay on all night, but in vibrate, so if someone does need to reach me in the middle of the night the phone lights up, vibrates, and wakes me up so I can take the call.

I tested your theory.
Phone OFF, Haptic OFF, vibey-vibey = YES
Phone ON, Haptic is OFF vibey-vibey = NO just a big bright room illuminating shock in the night when it turns the screen on to let you know it is charged.
Aha! So then a short term solution is to cover the phone with something, or place it display down? Until someone figures this out, that is.

What does your TF do when closing the dock?

What does your TF do when closing the dock? Will it stay off and asleep?
I just got my B40 dock back after RMA (timeline and replaced parts number summarized here). I didn't really pay attention to how it was before I sent it because I only had it for a few days, except that it didn't sleep even when MobileDock Battery saving mode was set. Now after the RMA, it stays asleep correctly, but when I closed it in a darkened room, I noticed a light coming from the gap. It woke up!
In short, opening and closing the dock would behave like this:
1. While open, press the power button on the tablet (or the lock key on the dock). Table would go to deep SLEEP and would not wake up with a keyboard tap. However, as I close the dock and it approaches about 5 degree angle, the screen would turn ON and, worse, it stays on. Pressing the power button would not turn it off.
2. While ON and not asleep, close it. As it approaches 5 degree angle, the screen would turn OFF. It would turn ON as soon as the dock is opened again (regardless of how long I left it closed).
FWIW, the TF is B50 on Revolution ROM 2.1.0.
Edit: reluctant of another RMA, is there a microswitch inside the dock that detects the open/close position? If so, I might just disconnect it unless there is a software fix.
There is no switch. There's a magnet right beneath the - button that tells your TF to go to sleep when you close it and wake up when you open it. Don't put it to sleep before you close it. I have b60. When I press the power button before I close it, it would still stay asleep and wakes up when I open it. It's not a dock issue. It's a TF issue. May be the b50 is built differently. Don't know.
I uninstalled "No Lock" and now the screen stays off in scenario 1 above. But looking at CPU Spy, it wasn't deep-sleeping and instead it stayed at 216.
Not doubting you, but how did you know that your B60 was deep-sleeping for sure?

I don't. All I know is that my battery lasts forever. Besides, if it doesn't go to deep sleep, then fine. I don't care. Like I said, as long as the battery lasts me the whole day without me worrying about charging, I'm good.
Why are people so anal about this sleep thing? Get an ipad if you want your device to deep sleep that badly.
I think there is a difference in being anal and trying to be sure about what our device is donig -- especially after one has just received it from RMA.
Being in XDA already makes us more attentive about our devices than the regular population, so can't blame someone for checking.

Actually, no. I think it's the opposite. If you're here in xda then chances are you are fine with some of the imperfections that come with our devices. That's why we mod.
It's the ipad users who expect things to be perfect. Myself and many others have pointed this out many times. iOS devices crash just as often as everything else. The only reason people think they don't is because when they do crash there's no error message. One moment you're in an app and the next you're on your home screen. iOS is built that way. It's like sweeping the dirt under the rug to give the impression that the place is spotless.
why are we even talking about iPad? Geez...

My phone`s display is turning on solely

Hello to everyone,
I have a problem that makes me angry every day regarding my Motorola Droid 2 Global, even if I love very much this phone. My phone`s display is turning on solely. This fact makes my phone`s battery to drain very fast. Thus, my phone lasts one day and some hours. My phone`s display is every time at 45%-55% as consumption. I mention that I have 2.3.4 Android Version and 4.5.629 System Version. So, from all I know, this Android version doesn`t have in pocket detection. I saw already that a lot of people have this problem.
Thank you very much for your help!
All the best!
Any idea ???
not sure what you mean, solely?
It won't turn off?
I would wipe cache and/or data, start over
Hello,
Yes...I am locking my phone (my display turns off) and after a time my dispay is turning on without any action from me and after that it turns off. Unfortunately this fact happens not a single time. Thus my battery is drainning very fast.
The D2G does in fact have in-pocket detection, but in my experience it does not work very well.
Is it possible that the keyboard is sliding open, even just a few millimeters, inside your pocket? I find that happens with mine occasionally, and it doesn't have to open very far at all to turn the screen on.
Hello,
I did a Factory Data Reset. Now I maintain my D2G under observation. Apparently, now, all seems to be ok. On the other hand, my phone display is at 30% as consumption.

Only switches if connected to dock (power?)

Hi, I tried to search on XDA regarding my problem but got "Sorry, search is down temporarily" or whatever. So, here it is!
One of our kids spilt some drink (water I think? I wasn't here when it happened) on the XOOM. And now it seems it will only switch on if it's on a speaker HD dock that I have. It wasn't connected to anything and in a leather case when the drink incident happened. It shows 100% battery and on charge when on the dock but if I disconnect the power, the XOOM switches off.
Does anyone have any suggestions on what I should try or look at? I hardly use it anymore but the 2 kids do use it to watch shows/youtube and play the odd kid under 3 friendly game so I'd like to extend it's life more than needing to keep it on the HD speaker dock, I know our 3 yr old will turn it up full bore going "I can't hear it daddy" and giving her cheeky grin hehe.
I'm up to doing anything, I did put my HTC ONE X semi recently in a bag of rice for several days after our 1 year old decided that it would look better being in a bucket of water (I see a pattern emerging! Plus not having the XOOM actually physically connected to a power source while the kids are using it would be a load off my mind *IF* I can somehow see if I can fix this issue of it needing to be on the speaker dock to turn and stay on.
Thanks! And ask away if need me to check/look at anything.
