I just noticed something with my phone. When I am charging my phone it takes a really long long longggggg time to charge. Usually more than 8 hours. I kept tracking the charge and usually it remains on 99% forever. Sometimes if I get a call, or open the phone to check how much battery life was charged or just anything that makes the phone active a minute later its finished the charge. I think my charging is messed up and my phone will remain on 99% unless I make it active so it registers it as complete charge. Is there a setting or something that I am missing?
bump .
Is 99%-100% a big issue? The 8 hour charge sounds too long, but is that from the mains charger or from a usb charge?
Does the phone actually charge correctly & just not show the battery status properly? (charge it on the mains for 2 hours, then use the phone - if it lasts the day then its probably just the indication playing about).
Were you charging from the main USB port on your computer OR via the USB hub. there is a huge difference.
If you were charging through the USB port from your computer, you would be getting power exclusively for the phone
if you were charging through the USB hub, then your phone is fighting for power with other devices so therefore less power going to charge it.
your other choice is get yourself a cradle so you can mainline from a power outlet and also from the computer directly.
Goodluck

A self-powered (not bus-powered) USB hub would be able to deliver the same 500ma/port that the controller on the motherboard would deliver. In reality, most USB ports (both on motherboards and hubs) can deliver more than that, because there's a lot of poorly designed USB devices that'll draw more.
true. I did forget to mention self powered ports, just because I rarely have those kind of hubs. Godefroi is right. If your USB hub is powered via an adapter, then that should not be a problem, otherwise it can be either the cable or even the port itself.
Fuze - power outlet wont charge
I am getting really annoyed by this, someone please HELP!!! I have a Fuze and for some reason for the past few weeks my phone will not charge on a power outlet but it will charge on a usb and with the car charger. I have tried my dads charger same thing so i know its not my charger...
SOMEONE PLEASE HELP!!!
When I plug in my Infinity to start transferring stuff from my computer...it doesn't charge. I don't remember if I read if it worked or not? Anyone want to confirm? I know someone said something about the dock not being able to charge, but the tablet should.

I don't think the USB on a computer is powerful enough. My old iPad couldn't charge from a computer either.
Sent from my 3d porn machine.
Someone in the TF300 section mentioned that theirs would only charge from USB if it were completely off, and even then it charged pretty slowly. I wouldn't be surprised if the 700 were the same.
Mine charges when I hook it up on the USB port of an Ubuntu machine. But very slowly since the current is low.
I've heard a lot of different tablets don't charge via USB. That sucks...it just drains away battery while sitting there copying, slowly might I add, via MTP. I'm charging it now...I'll let it sit and transfer some more after a full charge.
Same, no charging from laptop.
I'll live though

Well unfortunately the only way to move large files to my tablet is via MTP and if my battery is getting low then I'm screwed lol.

Yea, I had about 24% battery when I rooted and it was worrying me to since it wasn't charging at the same time. Then I realized that 24% on a tablet is a lot more than 24% on a phone. Whew!
I hope it was not a dream but i plugged my tablet on my laptop and, while it was in halt mode (thus not power off per say), it charged itself up to 100%. So basically, my answer would be that it does charge itself on a computer, but it is far from being enough to cover both the use of a tablet and the charging process. And btw, since mtp is awful-as-hell slow, shouldn't we use like ftp servers or through-ssh transfers ?

There are a couple of mentions in the manual regarding the USB charging.
The first one being "Ensure that your ASUS Transformer Pad is turned off before charging it via your computer's USB port."
And the second, "The ASUS Transformer Pad cannot be charged via the USB Dock cable when it is connected to the mobile dock."
So, I guess it proves that USB current is just not enough to sustain tablet's use and charge the battery at the same time.

I know what you meant, but can't help noticing it should be about the speed of light anyway...
Some of the newer tablets are using usb3 charging plugs for the wall outlets. If you know some or have a usb3 port on a computer, you could try that and see if it charges faster than the us2 ports. The t300/prime/t700 all use usb3 plugs.
I transfer stuff by the micro sd card, adapter, and my computers card reader. It's not as convenient as plug and go but I'm usually transferring video files to watch at work and they are large.

I thought that MTP was already bad, but adding the slow I/O on top of it is painful. What's the best way to transfer stuff?

You hit the nail on the head. I think I saw someone here mention theirs would wall charge if they had used a usb extension with the wall charger - and it turned out that the extension was only usb 2 which prevented charging.
I posted a thread about this in the Q&A section.
Basically, from my own experiments and some other people's observations in that thread:-
If you are using the tablet while it is plugged into a USB port, the power will drain very slowly or maintain the same level.
If you plug it into a USB port and walk away, it will power up.
I left it plugged into a high power USB 3 port at 78% and left it for about 4 hours, when I returned it was at 97%. and it continued to read as "Not charging"
For some reason, when the tablet is plugged into a USB port, the battery info says that it's "Not charging" but it is.

-------------------
There is a small trickle effect of power which is why the manual says to have the tablet off. That trickle effect is what you are seeing. It could be a computer doesn't supply enough power to its usb ports regardless if it's usb2 or usb3. The wall adapter could be pulling more power in it's design. If you search amazon you can find non Asus data cables. I've used one on my prime after my cat chewed the original. I think it is like 6 bucks for the cable. I don't know there is an off brand product for the actual wall plug. But it's something to look into if your interested in having more than one recharging locations.
I'm not so sure that makes sense to me. 30% increase in power in 4 hours, seems like more than a small trickle effect of power, and doesn't the infinity manual says you can charge via USB.

USB is 5 volts. Asus Transformer uses like a 12 Volt Charger. On my TF300T, the pad would actually still lose battery life if I put it on performance mode (rooted 1.6 ghz overclock). On balanced it would depend on what I was doing. I imagine the TF700 is the same. On the plus side, because the charger is 12 volts, it also charges the battery a lot faster. Plugging in my ipad 2 into my iphone charger seemed to recharge so slowly.
I dont know about the tf700, but I downloaded the Asus Ai charger and i can charge the ipad2/3 and the ipad shows that its charging. It a different case when I tried plugging in the Asus transformer prime... nothing.. Its wierd and Asus charging program lets the ipad charge but not the prime.

This!
As much as I love this machine, its software is terrible.
My Photon Q won't charge off a PC USB port, or my laptop. Is this common? Thanks.
Are you using the usb cable that came with the phone? Reason I ask....I've discovered this phone is extremely picky about the cables you use. So far of the ones I have on hand, I can only consistently charge while in the car using my Belkin usb charging adapter with the Motorola cable that came with the phone. That includes a fairly nice ferrite core 6ft usb cable I got from Monoprice...which it works fine at home on AC, but in the car it stutters back and forth between charging and not charging.
Just today I used a cheap USB cable I bought off of ebay to charge my PQ using my laptop.
Its one of the ones sold as "HTC OEM USB Charger + cable" on ebay for like 3 bucks.
I also charge it at home using a green 3m cable from ebay, also bought for like 3 bucks lol.
Does it require that drivers be installed on the PC to get a charge? I've tried a few cables that I have laying around. I'll see if I can find other cables to try. The weird thing is if the phone is off, and plugged in, the LED lights up green, as if it's charging. But using the same cable, if the phone is on, it won't acknowledge that it is plugged in.

No, I wouldn't think so...
I've been able to charge off of many different USB cables on my Q. Not sure... Only thing it's been picky on so far is the wall wart - cable it hasn't seemed too picky about.
If its an old desktop with USB 1.1 it may not charge, and many laptops won't allow charging via USB if the laptop itself is not plugged into AC. Just a thought.

Very good point ^^^. I've heard some laptops, even when plugged in, still don't provide enough juice to charge (some) devices. Perhaps your laptop is one of these low-power USB port devices.
ive noticed that this phone is picky about what charger you use. i have a hard time charging on my pc as well. and certain micro usb's i have dont seem to charge it well either. needs to be the stock plug it came with.
I've basically given up at this point. Blackberry AC chargers work well for me, so I'll try and track down a few more of them. Otherwise, nothing is consistent. The desktop I've used has a plenty big enough power supply, and it charges my Epic with no problem. My personal laptop and work laptop both charged the Epic, but not the Photon Q. I guess I'll just have to carry around a charger instead of a MicroUSB cable when I'm on the road with my laptop.
Thanks, all.

All,
For what little it's worth, I just noticed that the words "Not Charging" come up on the lock screen whenever I connect to the USB port of my laptop or desktop. So the PQ knows it's plugged in; it just refuses to accept the charge.
Also, whenever the battery completely dies, the phone will start to charge. It will charge for a few minutes until it has enough battery to turn itself on. As soon as it turns on, it stops charging, and a minute later, shuts down because of the dead battery. Then it starts charging again. This basically gives me an endless loop of the phone charging, starting, discharging, and shutting back off. I can't even get it to stay off long enough to get a useful charge without turning on automatically.
Yeah, the only issue I've had with this phone at all is the extreme 'quirkiness' it has in regards to charging on anything other than the stock usb cord & power adapter it plugs into. Even using the Moto vehicle dock for the Q, its completely hit/miss on charging. It will *often* go into that 'Not Charging' state where its kind of keeping sort of a baseline/'stalemate' of the current charge level for me, not really going down but not charging back up either. Not really sure what's up with that. With my vehicle dock for the longest I kept thinking maybe my cig lighter port on my car is bad, but I don't have issues with my radar detector at all.
Had the same problem with the not charging a few days back. I was leaving the phone in Mass Storage mode because just getting it into Mass Storage was a headache originally.
Hooked it up to it's original cable and woke up with 65% battery. Switched from mass storage to charge only and it started charging.
Not sure if it was caused by being in Mass Storage and wouldn't charge but now I put in Charge Only before bed.
It always works (in my experience) with the original cable that comes with it regardless, its anything else where its quirky.

Isn't there a setting in ##3282# that enables and disables USB charging? Y'all have probably thought of this already. Anyways just thought if throw that out there. This is my first android that was not a low usage device. I know very little about it. I seriously think xda should make tee shirts that say "everything I have learned in life I learned from xda".
My phone was not charging in debugging mode yesterday.

Hello,
I didn't use my tablet since 2 month and last week, i installed team EOS 4.2.2 JB rom.
After, my cable did'nt worked, When i tried to conect it to my computer, there was an error message that the tablet wasn't detect correctly.
And when i put the cable into the charger and the table to charge on the wall, i saw the icon on the right corner of the tablet charging but in the information battery, i sax that "Disconect" and the tablet % didn't grow up.... So i thought the cable was dead and i bouth one new on ebay.
With the new cable, no problem the tablet was detect and the charging with the charger was good. But after 2 days, i had new problems.
when i conect the tablet on my laptop, all is OK, the tablet is detect normally. But whn i try to charging with the charger on the wall, the tablet doesn't charge. I see the icon in the right corner is charging but in the battery informations, i see "disconect" again and the battery doesn't charge.
Yesterday, i saw a topic that i can put the charger on the freezer, i put it alle the night and i tried this morning but nothing the tablet does'nt charge.
On the charger, there is 2 parts, I open the little part with removing a screw and i tried to little move the 2 metal parts but nothing alwas the same problem.
So i think now the problem is not the new cable but the charger.... I know it's a specific voltage and if i try with my HTC ONE X charger, this will not work...
But maybe it's a problem with the tablet connect port?
I changed the rom and i installed the Cyanogen 4.2.2 this morning, and now when i conect the cable, with the computer, it's OK i see my tablet but the icon on the table isn't charging and i see "disconect in the battery information". And with the charger wall, it's the same, i have charge icon and i have disconect in the battery information
Do you think i must buy a new charger?
Sorry for my poor English my French
Try a trickle charge from the USB PC > Tablet
Plug the tablet cable into PC USB port and turn off the screen, then leave to trickle charge overnight
If you have the screen on it will not charge, so best to leave it off for a few hours to test if it is a charger problem

When you use PC USB to charge, it will not show charging on the screen, you have to leave it overnight for best test results
The freezer trick should only be used for about 20 minutes just to cool the charger down and reset the cutout
Try trickle charge overnight, if it works, its the charger
I think this is because tablet use a lot of power when in use and that is why the tablet is discharging when you use it. PC has even less powerful USB charger so the tablet will probably be recharging VERY slowly or even discharging when you use it.
You should leave tablet overnight to recharge and it is better to charge it in one piece than constantly plugging and unplugging it from PC.
Have a nice day,

You should be able to charge and use it at the same time with the actual charger plugged in, but you are correct, with the PC you can not use and charge unless you mod your USB ports for extra power
Ok i will try to conect the tablet (power off) all the night to my computer but i think it will not charge...
And if it's not work, it's not a problem with the cable because i can use the cable to transfer media PC> Tablet, so it's a problem on the tablet connector?
Hello,
My tablet was charging all the night. She was at 22% and now 38.... It's very slow!!! But now, i know that my tablet and my cable are OK and my charger is the problem.
There is a solution to repair my charger or i must buy an other?

Try this, separate charger and its pins, then take it along with the cable and put it in a zip pouch, now freeze for say 2 hrs. Take it out let it return to normal temperature and then try charging. Remember freeze them in a zip pouch (air tight)

Last night I was getting ready to flash CM11 via adb sideload when I dropped my phone from less than 50cm and my computer suddenly stopped recognizing it.
I thought it was my USB cable or my Windows installation that was going crazy but when I tried to charge it, it just wouldn't. In fastboot, all i see is Battery OK but when I connect it to the wall socket, it doesn't show "Charging".
Battery is not full, it was around 20%.
When I power it off and connect it to the wall socket, the screen doesn't turn on, it just vibrates for a second and after that is totally dead. It charges, but it's totally dead and won't show the charging progress bar.
It's like the micro usb port is half-dead.
Any thoughts?
Yes man you night have broken one of the pins. You should try the wireless charging mod, I'll give you the link in a bit. But if you use your port a lot you should order a replacement online.
I saw a video on YouTube that recommended charging the phone with a higher amperage charger. I grabbed my Nook charger and left it overnight. When I woke up, it was 100% charged so then I connected it to the computer in fastboot mode and it finally showed "Charging" and could use adb.
I hope it's fixed...
