Hi there
Even before I bought my Treo, I knew it wouldn't charge through USB. Since I didn't want to fiddle with the power cable at the same time as I was syncing, I only connected via USB for as long as it takes to sync and then disconnected again.
But today, I forgot to disconnect for quite a while. When I noticed, I expected the battery to be down, but it was back at 100%!! I will test this a bit more, but has anybody else noticed this? Or is the battery meter confused?
Cheers

I read in another thread somewhere that the USB sync cable has a bit of trickle charge to maintain the battery level but not fully charge it. It would obviously be great if it does charge the phone, then I don't have to go out and buy a USB sync/charge cable. (Don't like lugging around the charger).

Thanks for your feedback!
My observations today are that it really is charging - slowly but surely! I might get the 650 cable mentioned in Jason's blog. Thanks for link!

hmmm....
Well having had my Treo 750 for 2 weeks now if I have ever left it plugged in all it seems to do is suck my juice I just disconnect it after using the USB! oh Well, looks like it's cable buying time for me!

I got a combined sync & charging cable from gpsforless - works a treat
Well after reading this post i tried and test my 750v for a whole day. My observation is that yes it does charge but very slow. When i connected my Palm battery was at 82% and even after playing and hacking my palm whole day battery was still at 82%, which mean it does work.
Hey, yesterday i was working on my two month old TF and it was working fine. Battery went low so i put it to charge and it charged fine, until an hour later or so where it didn't charge anymore... i tried connecting the charger to the dock and it wouldnt charge either... the battery is almost 35% and i have it shutdown so that it wouldnt die on me if i want to retrieve any data...
the usb cable is working since i tried syncing with my desktop and it was fine...
CAN ANYONE HELP PLEASE.... especially that i have my exams in a week nd all my lectures are on the TF... HELP!!!

I am in the same boat...mine DIED completely....nothing is working...what is happening...who knows...
Thats just uncalled for..
any insight will help..
Thanks
I had the same problem and concluded that since the dock wouldn't charge either that it must be the charger that was faulty. I found that the charger seemed to work again after spending a few hours in my freezer. I read a bunch of posts from people with similar issues and this worked for them. Apparently the cold resets a sensor - seems improbable but who am I to argue because it worked. So give that a try.
this just happened to me, like 1 hour ago. neither the dock or the tablet would charge.
take the charger apart, i.e into the 3 pieces, cable, uk( or US/EU whichever you use) adapter and charger pack. check the small black pin at the bottom of the uk adapter, if that pin is broken off there is nothing to secure the 2 contacts in the right place and the charger will short out or not charge, if the 2 contacts dont connect properly the charger wont function at all.
the small black pin on the uk adapter on my charger had snapped off, so the charger wouldnt work as nothing was securing the contacts.
solution= get the super glue out! put some glue around the area where the small black pin should be( mine had snapped off), connect the uk adapter and the charger pack and most importantly make sure there is zero gap between these 2 pieces by pressing the 2 pieces together until the glue sets.
now put the cable in the charger,connect to dock or tablet, now charges no problem and has been the last half or so hour.
the transformer charger is a badly made pice of junk.
I have an iPaq 111, part of the 110 series. It's been stored in a closet for over two years. I hooked a batter charger to the battery itself (outside of the device) to charge it up enough to be able to take a charge once I put it back inside the device.
Once I did that, it powered right up, and everything worked perfectly. Then I went to unplug it, and surprise to me, it shuts off.
I've tried EVERYTHING, HP doesn't even publish there ROM. Found a setup utility to download to my PC to access my iPAQ, but it's in German, and high school was a long time ago so it's hard to understand; but what I can understand enough is that it cannot find a device. Same goes with the extension I installed through HP's website, it only finds my HP computer.
I've plugged it into my computer and the light is GREEN, suprisingly, but it does not turn on. If I plug it into the AC power adapter, it DOES turn on, stays green, and once on the homescreen, shows battery at 100% (was 23% onwards today when I was charging it). My voltage meter shows about 4 volts coming from the battery. Contacts on all ends are clean. ROM issue? Yes, I have tried soft and HARD resets.
Any help will be much appreciated. Please please please! THank you!
Battery is not fine, its dead. The proof is the fact that on AC power it turns on, but not when connected to.USB. AC power has enough amps to directly power the device, USB does not. When connected to USB power is indirectly drawn, as the phone attempts to use battery power for operation while charging it at the sametime, thus lessening the total draw. It still however needs battery to work.
Basically, the battery is dead. By a new one of eBay.
icenight, THANK YOU for the reply, it was so quick. I have figured it was the battery, BUT:
I've checked the battery with a voltmeter and it shows over 4V- using my good Fluke. Also, when it's plugged in, it progressively showed the battery charging and it's now at 100%...
Are you still thinking it could be the battery? Not enough amps from the battery? I hate to sound cheap, but it's more about the wait- I want to eBay this iPaq since I don't use it and it keeps getting in the way!
Thanks again
iPaq still not working
New battery arrived. Still does the same thing. I've read around and it could be the ROM, but it wont stay on when plugged into the PC USB port. Computer sometimes makes a noise when I plug and unplug it though. Even put a homemade "in-line" power supply to it using a 5V 1.5A adapter. This allows it to stay on when plugged into the PC usb, but there is no communication. This thing is a pile of **** I tell ya.
Any help would be so much apprecaited. Thank you so much. I can barely get past these "captcha" thingys.
Regards,
Robert
I touched on this in the EOS thread, but I've discovered it's probably not the ROM's fault and some other problem. I was staying in a very old hotel, which I assume had very poor electricity (not sure if relevant, but wife's iphone was charging slowly too, so maybe it could be part of the problem - way too low voltage or something). Plugged the (TF101) in and it charged barely, if at all. If I recall, the wall adapter got hot on the first try (didn't really take much notice as this has happened semi-frequently since I got it - might describe it more as "warm" in the past, where in this case I'd call it "hot") and from then on probably charged to about a max of 25% in 24 hours. So assuming the problem was the hotel, I tried it again at home, where I knew it always worked, and it still doesn't charge. so...
TL : DR - charger isn't charging - thought it was the electrical supply but it's not (though it could have started the downward spiral of breakage)
I tried freezing the adapter, bending pins, hard reset/cold boot, etc as per different threads on the subject. Didn't help.
Tried plugging the USB cord into a PC and it shows up as a connected device - doesn't show charging on the Transformer, but I don't think it's supposed to - so I think that means the cord is okay.
I plugged a Blackberry with its USB cord into the wall charger and it shows "charging" so it would seem that part is okay - but not necessarily definitive proof as it's a completely different device, just my only other USB device I could test.
This all happened right after flashing the newest EOS Jellybean ROM (from #70 to #72 - no full wipe - cache & dalvik wipe only), but I've switched back to Megatron, which worked perfectly in the past, and nothing changed with the charging. So unless it's possible for parts of the EOS ROM to remain (after a full wipe this time), it would seem the problem is with the charging circuit or the battery itself, right? Not sure what steps to take to test that.
I think I will probably try a new charger anyway, as that seems the cheapest of the $$$ options to try first, but are there any tests I can do in the meantime without spending money on replacement parts? At the moment I have it plugged in with the power off to see if that does anything - will update with any positive results
(Sorry for long-winded question, I wanted to get as much relevant info in there as possible. Hopefully I got it all)
Start by buying a new usb cable, that fixed my issue. Wall socket and usb port only trickle charged my tf101 (about 48 hours for full charge) tried all the freezing, bending pins but nothing worked. I then brought a new usb cable as a last resort (Wall warts are quite expensive so i was apprehensive of buying a new one) and it started charging straight away. seemed strange because the charging issue was just out of the blue (No damaged to the cable)
doubt this needs an update, but my new charger and (longer!) cord came today and it's charging my tablet perfectly. thanks for the info
now to catch up on 2 weeks worth of ROM updates
Dunno if its the right thread but I was also wondering:
My TF101 charges perfektly with the Wallcharger (TF to USB Cable + Adapter). But as soon, as I put
an USB-to-USB-Cable between Adapter and TF-USB-Cable to enlarge the range ... it wont charge anymore.
But: if I connect the same config it to my PC... I'm fully able to Up/Download/ ADB etc... so it can't be the connection
at all.
What's the trick? What am I missing?
Hello.
Yesterday I upgraded from KatKiss #018 to #019. Up to now #018 had worked perfectly, but today with #019 I noticed that when plugging in my charger (I don't have the dock), I didn't get the little 'flash' sign on the battery notification; going into the settings to look at battery usage, I noticed that i said 'Battery not charging' even though I had left the charger plugged in.
I unplugged the charger, turned off the tablet, and replugged the charger, and the tablet turned on, which it does when plugging in the charger and being off.
Has anybody had this problem? Is it really charging but not notifying it? If not, what can I do besides reflashing?
Thanks!
me too

me too, i just flash it usually,,, battery at 100% wipe cache system etc, when my tf reach 0% it wont charge, but when i charge in off mode ( shutdown TF ) it charge but so long, 8 hour only charge 20% need help to resolve this issue,,,
I have the same issue, battery will not charge. and it seem that it will not get supported here, no answer from the dev, please dev look it up
I am fine with kitkat 19. You guys above may give a try to change a data cable to charge your tablet.
not sure

If my tf port charge broken,why when off mode my tf wake automatically when connect charger?
My charger perfect work in my friend tf,also when i connect to pc it detected by pc n can transfer data,if it broke,it cant be detected,right?
Sorry for my bad english
Best regard

No problems for me and most people I guess otherwise they would stay away from the rom if it was not charging
Try to power off completely your tablet, then cold boot.
Try to change cable, try to test with another charger.
If that doesn't help do a full wipe and a clean install and test again before reinstalling anything else on your tablet.
if that still doesn't help, follow the procedure to report an issue in my signature, I'm not psychic.
Hello.
I have a problem related to the battery as well. Ever since I flashed to #19, my tablet and dock battery seem to run dry very quickly in sleep mode. I have come home from work to occasionally find the tablet unable to boot (it had a dock charge of no greater than 75% and a tablet charge of 100%) and when I plug the charger into the dock and then boot it, I find both batteries have next to no charge.
This is only on timduru's KK#19. I never saw this problem on #18 and below, or any of the previous 'droid versions (4.3.1_029 or 4.2.2_226).
I am currently letting the tablet's battery run to empty and then I will be charging the dock and tablet separately, but this is the first time I've ever encountered this problem.
okay

thanks for reply, i will try 3rd method because i have do 1 n 2 method but no use,,,its still can charge but in off mode, but it took much time,,,12 hour only get 35% battery,,,,clean instal?format data too???i have do installation step,,,format system,cache dalvik,,,its happen when my battery reach 0%,,,i have try my friend charge,,,but also cant charge,,,but my charger can charge in my friend TF,,,,i will try change other ROM then to check if it also have the same problem...
KatKiss #20 no charging problems here

Did you try another ROM? I'm on #20 and I think I have (mentionable) more battery life. Not charging issues. Guess the fresh installment / wipe helped or an energy eater didn't survive the reinstall. Also I could observe two things (which I don't know of if they are related): Sometimes when the tab was docked it didn't charge. Second the the tab hat a battery problem. When docked and in sleep -> Dock empty next morning. I controlled this with Juice defender but weren't able to locate the problem in an app. This is now gone.
From my experience: I bought 2 power cable for the TF101 (only cable). One works as USB cable with no loading feature (not on USB 3.0 nor on the wallcharger). The other one works as USB connection cable and as wall charger. I can extend the original cable with USB to USB cable to transfer data and charge. I can't get any of that both two (CHEAP) cables to load extended or trasfer data. The two cables I bought at ebay were diffrent vendors. One for ~2,50€ the other for ~4€. If I remember right the original cable where much much more. What I want to say: There are huge diffrences in USB cables. Dunno. It would be a strange accident that the charger or cable broke when / while you intalled a ROM. Could it be that the "intelligent" battery stats are broken somehow? So they think the battery is full and therefor not charge? Or would the icon / indicator then show 100%? Does the icon get its information from the same source (or directly from) as the android battery management?
(ps: 12 hours for 35%=! ROFL!?? What charger is that?)

i have mention in other thread,,,my charger original from asus,,,my asus has 2 years with me no problem before,,,,it can connect to laptop,buat when charge in on mode it cant,,,my charger ONLY can charge my battery in off mode (device shutdown),i will try full wipe back to factory re root etc,,,and then fresh install,,,,but it will take more time because i am still wait fot 100% battery,,,

if it takes that much time even when it's off, it means that it's only charging at 5V.
Also at 5V it won't charge unless the screen is off if I remember well.
There's a special pin/connection made in the cable for the charger to detect that it's a Transformer plugged that will make it charge at 12+V
There's most likely a pin/ contact broken either in your cable / charger /tab, that prevents it to charge at high voltage.

So you say you go with option #3 then because u already did option 2, right? Quote Tim on option 2: "Try to change cable, try to test with another charger.".
So you have 2 x THIS and 2 x THIS? Because that would mean, what Tim suggested I guess. As far as I know this is the only way ASUS shipps the original TF101.
I'm asking because most people that I know would buy another noname charger or even just a noname cable instead of horribly expensive original pieces. If you really got the 2 x 2 pieces shown above,
then I'd guess wether your tablet is broken or the software on it is broken. But again: Did the charging problem REALLY firstly appeared when intalled the ROM? Or did you install the ROM because of the
fault? Or don't you exactly know.
To point out again: It would be a strange coincidence, that both cables AND adapters would stop working exacly at the same time when u installed #19. If you use 2 different cables at the same adapter: Then it's possible that the adapter is broken and only gives the USB (5V) loading speed. If you use 2 adapters and 2 cables and tryed all combinations: The most likely something with the tab isn't cool. The software or the hardware...

Precisely what I meant.

I have loaded #29, and I started seeing this issue immediately. It was fine before that. After loading the ROM, it would only charge when TF is dead. I have the original charger and cable that came with it which was working fine before the upgrade. So, I don't suspect either of them.

I was going with #29 and #30. Havent seen or heard about any loading issues but that was related to loading the tab on an USB port ... What actually is an bad idea even on USB3.0.
