I've tried charging with its original charger, as well as a RocketFish 2.1A charger. I've also tried different USB cables with the same results. The battery stays at 0%, even after hours of charging (and while turned off). The weird thing is, this only seems to happen at my parents' house. My tablet seems to charge just fine at my apartment, albeit very slowly. But at my parents' house it just doesn't charge at all. Any electrical engineers here? I simply can't see how charging at a different house should cause cause problems. Has my battery gone bad? Should I send in for a warranty replacement?

You mention adapter but are you using the original USB cord?? It is very different from other android cords. Also have you tried different outlets at your parents house? Are you in the US or Europe? What do you mean by slowly? It won't charge as fast as a phone due to the larger battery size. I haven't timed it because I charge while I am sleeping but I approximate it between 4-6 hours for a full charge from 0%.

Hrm.. This is interesting.. I used to always charge my G1 with AC power. However past couple days, I was lazy and used my laptop USB to charge it. I noticed those days however the battery life was HORRIBLE! I mean I couldnt even get past lets say 9 hours without the battery being at 15-30% and this is without doing anything major. On AC I always got home with 50%.
Has anyone else noticed this? I am using the power profiler mode, so unless something goes out of whack on USB power mode, which I dont see why it would...
(Also I did turn off phone and back on to reset anything just in case) but its just a interesting thing that it seems USB charges suck?
Yes I noticed the same thing, used the computer USB to charge and only lasted about 6 hours of the day. I use the Wall charger and get about 9 hours consistantly. Not sure why but I have noticed this several times........
Mark
Every Tmobile rep I've talked to always say the AC charger does a better job of charging the phone.
Hrm, is this info on a G1 Wiki yet? Would be good info to pass around. My logicial guess is that USB charging can only allow the voltage on the battery to charge to "x" max. While AC power being stronger could bring the battery up more. I cant say thats fully the case.. but since the USB cannot supply the power max a AC could.. its possible.
I've got and idea for a little test, would be helpful to see a lot of different users results as well..
Get Battery Graph, run your phone dead, plug in usb charger and graph. then take a screenshot of the overall charge time, clear graph
Run it dead again, plug in AC charger #1 and and repeat
Repeat the process for each additional recharging apparatus
The reason I mention additional apparatuses is because I think my car's DC charger does better than both ac and usb (tho this will be hard to get a full accurate graph of) , also I use my gf's moto charger from time to time (i know bad mojo)..
This will probably take a few days as charging will take place at sleep time for me but this should give us an over all view of how things are working if we all get pretty consistent results..

I've had 4 different miniUSB charging phones and all of them have had this same behavior. I'm sure that the voltage coming through the USB isn't as strong as AC.
I have the same issue too...!!!
No offense.. but EVERY phone charges better w/AC versus USB .. This is not just a G1 issue .... lol

Indeed.
Also, USB charges at 500 mAh, while the AC gives double if i remember correctly.

Im wondering, if I use my usb while plugged into my laptop (for tether wifi app) will this hamper my battery life? I have the extended battery (2200mah) and I get far better life from it and to be honest I like the bigger size because the g1 felt too much like a toy to me before.
What do you guys think will this mess it up? I dont have wifi at home so the tetherwifi app is the only way I have net on my laptop unless I go somewhere where they have wifi. Cursed neighrbors and there password protected networks!
Might using a USB stepup voltage converter help? I've used it to charge my Nokia phone on usb in the past so it would reach the battery is full message.
The argument is usually that laptop usb don't output adequate voltage.
Its cheap and works for me on the nokia phone, Haven't tried it on the G1 yet though, can anyone find the ac charger's output info?
http://www.dealextreme.com/details.dx/sku.2649
yea this goes for alot of devices.. my ipod/psp charge pretty slow compared to wall outlet, however i didnt really see strength difference.. never tried USB charging my g1
I think it's worth noting I have the G1, My girlfriend has a HTC Touch(Elfin)
Both use Mini-USB Charging, both have 5V 1A Batteries (can't remember mA rating though)
Through a wall charger, my phone seems to charge quicker, but I get no longer out of it, the same behaviour is exhibited with the Touch. Both USB and the Wall charger are rated at 5V (It would/coul destroy componants methinks if it was any higher).
USB's Specifications say that unless a device has special permissions, It can only draw 500mA, with a maximum of 1000mA and a very rare (as in, one maybe two things use it) 2000mA.
Also, I have a custom made USB charger, that takes 3 AAA batteries (1.5x3 = 4.5)
It causes the phones internal battery to mess up, but does actually charge it (just a lot longer than other methods). It's more of an extended battery however, as it says it is charging, yet the battery life slowly degrades.
It's simple really and it has already been explained.
The USB port on a computer is limited to 500mA for most devices where as AC chargers like
The G1's can rpovide up to 1 Amp, even more/less depending on the chargers.
It doesn't depend on the voltage but on the current delivered. Less current equals
More time to charge and viceversa,
There is no myth.
As of this morning my TF nor the dock will charge from the charger. I suspect the charger itself is damaged somehow but I cannot find anything physically wrong with it from the outside.
EDIT: Weird, after the 20th time playing with it, taking it apart, reseating the USB cord, etc, it finally started charging again after hours of aggravation. Hopefully it stays that way....
I'm thinking the inner pins somehow lost contact with the interposer. I've also noticed that the adapter gets alarmingly warm when charging. As in it's hotter than the PSU I use for my Alienware m17x R2, which is almost hot enough to give a mild burn.
My charger gets pretty warm as well. I think because its charging the device at such a fast pace.
Takes twice as long to charge my phone than the transformer!

Yeah I'm just hoping this whole thing doesn't keep happening. Had the charger on the dock for a while before I realized it wasn't charging since there's no indicator other than the LED. I'm just glad I got the dern thinking working again. Figures it would get fixed not 5 minutes after I post here and send a ticket in to Asus.
I wonder if cutting a few vents on the charger or at least blowing some air with a fan might help. Perhaps there is a thermal protection shutdown circuit.
there are several threads about this here one;

i had the same problem, not had it since, something is definitively happening with the charger, changing sockets seemed to help
My charger actually died on me. It doesnt charge at all anymore with the included charger. I can still use the cable to charge off of USB, but that is sloooow. I bought an iPad charger (2 amp) and it charges a bit faster. At least I can still use my tablet until a replacement charger is available.
Just FYI I was told by Asus CS a replacement would not be available for awhile, and they wouldn't RMA the charger by itself.
Sounds like many of the charger problem is the contact between the country plug adapter and the charger itself. First thing I would do if it stopped charging is remove the country plug adapter , clean contacts and reinstall. Sometimes in the process of plugging in or removing the charger, you move contacts enough to either make or break the connection.
Loses charge significantly on standby
I left it on standby last night @ about 70pc. When i turn it on this AM, it is at 20pc Any workarounds?

Standby and off are very different states. In standby, it's STILL RUNNING. If you leave the WiFi on, it's still communicating over the network. Applications are still running in the background.
I did a test recently (right before I got my dock). I left the TF in 'standby' with WiFi on (turned off the sound) and went to sleep. About 9 hours later, the battery was down around 50%.
Next day I did the same, but I turned off WiFi. Battery ended up still being above 90%.
The workaround is turning it off. Disabling WiFi reduces battery consumption in standby, but it does not eliminate it.
And for the 'stopped charging from the AC adapter' issue, it seems that unplugging the adapter from the wall for a while seems to reset the charger.

I feel this is a shortcoming of honeycomb than asus. hopefully this gets fixed in a future update. Havent seen this behavior in any other mobile device.

Which part do you think is a problem with Honeycomb instead of Asus?
The dock issues or the power supply not charging? How can the OS be responsible for either? (save for driver issues with the keyboard, which Asus fixed with an update)
I actually had this happen to me, but reassembling the charger didn't fix it for me. I ended up restoring to fix it. Haven't had any issues since.
I had the same problem. Did as stated above... Left charger unplugged for 20-25 minutes, then gave it a try and now it's back to charging... All good.
Information of PSU model with known fault here:
http://forum.xda-developers.com/showthread.php?t=1081435
Possibly a related issue? My Transformer is now not charging although I believe either my cable is faulty or the connector to the tablet itself. I don't have my official Asus charger with me today so I plugged it into another USB power charger and I get nothing. When I plug the cable into my computer the Transformer does show up as a device in Windows however there is still no charging.
I don't actually suffer from battery life problems like some other owners. My problem is that it takes for ever for my phone to charge. My phone has been charging over USB attached to my computer for 8 hours and is only at 83%. When it's attached to the mains it's pretty much the same story. I'm not running any apps. 3G, WiFi and Bluetooth are turned on though.
How can I resolve this problem?

well, if plugged into a computer/usb, itll take much longer to charge. are you using the original usb chord? when plugged into a wall charger, how long does it take?
Current draw is about 700mah on average. Battery size is 2100mah. So it should take 3 hours to charge with the wall charger.
USB is another story. If you charge and surf at the same time it will be consuming battery rather than charging.
The problem seems to occur when I don't use the original USB wall charger. Are not all USB chargers the same? When I use the original charger, I don't seem to have this problem.
If WiFi was left on while charging on a computer USB port, would this effect the charging speed?
My device has the charging icon on the battery picture at the top but the battery level itself isn't increasing. After 4 hours on charge with no use it is still on 13% as it was before I tried charging it. The battery level isn't decreasing when in charge either. The wire itself is a bit broken would the cause the problem and should I just buy a new lead or is it likely to be a problem with the device/ battery ?

Do you mean the charging cable is damaged? If that's the case I would definitely start there and try a different charger first.

had a lot of issues with the original charger cable, it did not connect very well. using another charging cable from my phone solved the issue. btw my charger itself well was overcharged I guess and now I can;t use it anymore. but enough other ones are laying around.
Solved - Battery won't charge
Like many others I've had charging problems with my Nexus 7 since it was almost new. It would intermittently not charge (even though the display indicated it was) or charge very slowly. I tried every suggestion listed in the forums that didn't involve opening the tablet. None of them made any difference. The charging issue gradually became worse until a couple of months ago when the battery wouldn't charge at all while the tablet mocked me with it's cheerful charging indicator.
For my tablet the problem was solved by changing the USB connector in the tablet. It took 20 minutes, cost $10 delivered (on Ebay) and is now working fine.
Hey guys, i have a really intresting problem. My LG G6 H870 is charging good in normal charging but if there is fast charge icon seeing in the battery phone stopping charge. It is being like full charged so adapter stopping send electricity. But phone still saying fast-charging x hours x minutes left to full charge. I sent my phone to service but they couldnt find a solution. My adapter making high frequency sound when fast-charging too. You know this sound from %100 charge. If your phone full charge your charge adapter making same sound. But it is happening to me in less than %100 battery. Please help me. Intresting thing is my phone charging normal in normal charge. (Charging 6 hours or 3 adapters) Only fast charge adapters cant charge.
