Has anyone had a problem with extremely slow charging? I would plug my phone in and wake up 6 hours later and the phone is still not charged. It's even worse now with the extended battery. 7 hours worth of charging and I'm only at 85%. I'm rooted and using the de-bloat rom without the kernel, but it was like this even before the root. Has anyone else encountered this strange issue. I have been using the stock HTC charger.
mine charges in a couple hours using the wall charger and wifi hotspot. In the car or via computer USB, it charges very slowly and if wifi hotspot is on, it loses charger over time.
I typically turn my phone off to charge; speeds things up 2-3 fold.

Mine doesn't even take an hour . Power it off and try it that way and see how long it takes.
damn mine charges super fast compared to my nexus s i had
If you have plug to the computer it might take longer but not 6 hours, on the wall it only takes like an hour or two to be fully charge.
If it's an issue just take it back and get another one.
Yeah I might have to return this phone. Do you think it matters whether I use the cable that came with the phone, or a regular usb cable to charge.

You need to look at the power ratings of the adapters you're using. This behemoth phone can receive 1000ma, while many car and home chargers (like Droid1) are only rated at 500ma. I'm still trying to figure out what the power draw is on the phone when just idling (battery monitor widget is hard to understand), but if the phone draws 250-500ma with regular usage, its going to lose charge plugged into USB (rated at 500ma per port) and running hotspot (drawing closer to 600ma). That's -100ma.
These numbers are guesstimates. I'm not sure if the cable itself can pose limitations, but would suspect that as long as there's no shorts in the wire, it would be able to handle any of the above currents.

yeah i find it impossible to charge the thing on USB, and it takes forever plugged into the wall with the charger it came with.
Had an evo, and it would almost full charge (from the time it said to plug it in, so 15%) in about an hour and a half. The thunderbolt seems to take 3 hours ish for me. I know I can turn the phone off, but since it usually charges over night its not a big deal, I just think it is interesting that it is so different.
yeah I'm one of the folks who charges FAST. It has really surprised me...I actually thought everyone was charging super fast until this thread.

+1 on looking at your adapter. Use the one that comes with the phone or make sure that it's rated at 1000mA/1A or more. I tried a MicroUSB adapter I had lying around that came with a bluetooth headset; turns out it only puts out 200mA, so the phone would take forever to charge on it.

with an output of 200mA I would be amazed if you could get this phone to charge at all, without having a custome kernel and underclocking the processor. If anything I would see it maybe staying same battery percentage.
Overall I feel this phone does charge really slow. It is way slow charging on a computer. I was charging it and just doing some light texting and after 4 hours the battery only went up by like 25%.
I have a second wall charger rated at 1000mAH, and after 30min it went up like 10%. This was with the phone off btw. With it on, but not in use, it went up like 4% over 30min. I'm kind of surprised how long it takes to charge. I've had no problems charging it at night. Plug it in before bed, and its full when I wake up. How does the 1400mAH battery size compare to other phones?
I did a little math too, the battery is a 5.18 W/hr battery. So with a 1AH charge at 5V, you'd expect the phone to charge in 2 hrs if only about 50% of the electricity is getting retained by the battery.
I've noticed that mine takes about 1hr 45ish mins to charge from completly dead. My Droid used to be an hour at the most.
i just checked on the adapter it came with, it's 200 mA...did people get better chargers than me or something? Mine takes forever to charge also...been stuck at 99% for 30 mins
EDIT: nvm, i was looking at input, not output...still isnt moving from 99% to 100% though

@lorijuan1024 im with you man the Nexus S took forever...... To charge
its impossible for me to charge it through the computer, it went up 5% over 3 hours, wasnt on hotspot, sending texts.
Mine charges fine on anything, I am using my old fascinate charger.
Charging speed seems to fluctuate for me... sometimes I get lucky and its fast. Other times, not so much.
Hi guys, I got 2 subject so I thought I'll just make one thread for this.
I'm from EU so I used my US charger with an other plug. Seemed to
work great, doesn't complain like it does with my HTC phone charger.
But now the charger gets pretty hot, along with the USBplug that is in the charger. Should I be worried? I would say its about 50-70celsius.

So I got Quake from preware, but it doesn't work with touch only (even tho there r touch controls?) so Im wondering if its possible to get it working with this:
http://icontrolpad.com/
That would be nice with the snes emulator also so I might buy it, its very expensive tho but I like the oldschool'ness of it.
You're likely to burn it out if you keep using it, don't leave it on unattended.

Sure? Does your get hot?
The charger should handle ~220v as we got here. So I don't get why this shouldn't work.
Isnt there a way to find a compatible European charger without paying 30$ for the travel pack?
Pretty much any micro-USB charge will charge the Touchpad, it is just some will be quicker than others. I am charging from the USB port on my laptop at the moment and it has upped the charge by 8% in the last hour or so with the screen off.

Yeah but the normal one gives about 30% on that time. But as I said, it should work, no problem. I don't think its uncommon for it to get hot but I'm not sure tho
My official charger gets quite warm, together with the USB plug. Clearly that is the only device that will charge at full speed and without a warning on the screen. However, as I was trying to point out, you don't have to go down the official charger route if you are prepared to either accept the on-screen warning or a slower charge rate. The Blackberry Playbook charger gives 5V 2A and although it comes up with the on-screen warning charges almost as quickly as the official unit.
I bought one of these http://www.mymemory.co.uk/iPod---iP...s-USB-Charger-and-Socket-for-iPod_iPhone_iPad the other day, rated at 2.1 amps (though the unit shows 3 amps). I get the dire message about not enough voltage or current but it works fine and quickly. Obviously I don't use the supplied Apple cable...
Hopefully I don't get flamed for this as I have been doing searches but so far nothing...
I got my HTC OneXL and that night I flashed Viper onto it. I don't know if it's the ROM or the phone itself, but it takes a really long time to charge. I plugged it in 2 hrs ago at 50% and I'm only now at 60%.
Battery life is hard to know length as I've had the phone a week and have been customizing and setting it up etc.
Is the charging a known issue to the phone or is it the ROM? I'm coming from the Iphone 4S and that thing charged up really fast.
Any help is greatly appreciated!!
Charging it from the pc or from the wall? Using the cable and power adapter it came with?
10 percent in 2 hours is slow. Typically in 2 hours I'll get about 50 percent or more.
If you have a 30 day faulty return policy I would take advantage and make sure they replace the power adapter too. Typically they would of course but I thought I'd specify just in case they wouldn't want to for whatever reason.
If you don't have a return policy available, I would try another usb power adapter for a couple hours as that would be my first guess as the culprit for this though it could also be an issue within the phone.

I had the phone given to me and it didn't come with the original cord. I'm using the cord from my Xoom so that could be it...
Sometimes I use the wall charger, sometimes my pc and sometimes the USB port in my car. Guess I'll have to try and track down the actual cord and see if that works. It'd be cool if those dots on the back had an actual charger that worked for them!

Charging from a PC is slow, and from a car is extremely slow. If the 10% in 2 hours is from car charging, it would not surprise me, and pretty normal.
MicroUSB chargers or cords from most phones will work just fine on the this device, but don't know about the Xoom. I suspect either the charge source (car, PC) or cord may be the issue here.
Also keep in mind, that after a ROM flash, the battery meter is not completely accurate. You have to do a charge cycle to full, then drain to 10-20% for the high/low "flags" to be properly set. This might be part of the issue. But I haven't seen it cause such a slow increase in readings while charging, so I don't think its your main problem.
Hello there,
I decided to open this thread as I've now had a bunch of issues with the stock charger that came with the device and it would be interesting to know if there's anyone else who's having this type of issues.
The exact issues that I've been having with the stock charger seems to be that the charger doesn't output enough of a amperage for the tablet to hold charge while in use, and even when it's not in use it takes almost 7-8 hours to charge from 50% up to 100%. It's as slow as if I would charge it from a regular USB port, if not, even slower and I don't really know why exactly this happens as it says that it's charging from AC adapter in settings.
To comfirm my issue was not related to the tablet itself, I used another charger that's rated at similar specs to the stock charger (2.1A) but with the same Micro-Usb cable that came with the tab. With that charger, it charged up from 50% extremely fast (around 1,5 hour) and I could even use the tablet while charging without any battery drops. So that comfirms two things, it's not related to the tablet or data cable but to the actual charger itself.
Anyone else that's been having this type of issues with the stock charger?
My tab needs max. about 3 hours to charge full and imo it's ok. Tried charging during Half Life2 gaming and can confirm that there's not a lot of charging going on, maybe 1or 2% in an hour. But that's ok for me, as long as it doesn't start to get emty while charging during gaming.
The charger is defective or don't bring enough power to the unit. I also get negative charge while playing high end games an also increase when i am, on Optimized mode. Many others has reported this situation on GeForce forums but nVidia is quiet about it.

I get negative charge even when doing basic tasks like listen to music or watch a video with the stock charger, so I guess my charger is faulty. I've already reported the issue to Amazon and they gave me a 50GBP partial refund (80 USD!) because of the faulty charger without having to ship anything back.
I just find it odd that theres many people that have the issue and nvidia doesn't seem to do anything about it either!

If i were you, i'll check with another charger doing normal stuff, if you still get negative charger maybe it could be your battery itself.

My guess is that a faulty cable or the charger itself is causing D+ and D- to not be shorted together by the charger, resulting in the tablet thinking it's charging from a USB port instead of a dedicated charger.
Does device status report charging state as Charging (USB) instead of Charging (AC)?
I admit I never even unwrapped the stock charger, I've got one of those nice Anker 40W 5-port chargers along with a bunch of 24/28AWG MicroUSB cables from Monoprice.

The charger appears as AC in settings, so it should be charging faster than it does.
I'm using a charger similar to what you use right now, a Dodocool 4 port charger that works great! However, I'm using the stock cable.
First make sure you are using stock charger and cable.
If you see discharge during non intensive activities you may have a defective charger. Nvidia has rma'd the charger by itself for people.
I have the same issue but my charging time is a bit better 3-4 hours. But what is really annoying that it makes a lot of electrical noise. I have a lot of things that I charge, but I have never heard this so load earlier. Its coming from the adapter, I can cleary hear from 3m. Anybody has similar issue? I try to record the sound, and send to nvidia. Maybe they will react.

I can confirm that this combo works a treat for my NST. I use it to simultaneously charge my G3, NST, N7 and some small LiPos. Fast charge.
Sorry to dig up this thread but I've had the same issue and i was WTF-ing like crazy until i switch the USB cable to a charging cable i got from a power bank... The charge time dropped from 6-7 hours to 2-3 hours. I'm not sure why, perhaps my cable is faulty or perhaps it was meant to charge like this, or perhaps it is supposed to be used to connect a controller only (both ends seem to have a controller icon on them)?

It's not due to the MicroUSB cable but due to a wallwart that's messing up the amperage I believe, as I've used the MicroUSB cable with other wallwarts and it charges normally then

You are correct. I charged the tablet at home 2 times this weekend and it's definitely an issue with the charger as it sometimes charges properly and sometimes it does not.

A bit hard to do since i got it from amazon.com when i was in the US (back in EU now) and there's no point in returning the tablet just for a semi faulty charger.

Contact amazon and tell them exactly about the issue, they'll compensate you for it probably. I got 50£ back from Amazon.co.uk for the broken charger, which is quite a bit of money.

Thanks for the tip, i'll give that a try
Well, same thing here. Just noticed it while using Skype. Battery dropped from 100% to 95% pretty quickly while charging.
I'm going to ask Amazon for another charger or compensation.
I have a 2.4A charger and still battery no good.
I lose around 2% per min of battery charge while idling with battery saving features on (2 cores shut off, CPU frequency set at 50% and Framerate locked at 30FPS) when ingame the battery drops 2-3 times faster. takes 2 hours to charge from 97% to 100% and 2 mins to lose that charge. I think I bought a Tablet that has a faulty battery as this is not acceptable. My tablet is unusable as the battery takes a couple of mins to lose 3% of charge and a couple of hours to regain the 3% charge only to lose that charge (and then some) when I try to use the tablet.
I have searched through the forum and tried all suggestions found, attempted to charge using a wallwart (known to be good) and USB (cable known to be good). Some background: last fall I was trying to flash the ROM and it got stuck in a boot loop. As I was visiting my wife in Taiwan (she teaches at a university there), I decided to take it to ASUS to have it looked at. They diagnosed a bad motherboard and replaced it, but not in time for me to take it home. It could not be shipped back because of the expense of shipping a lithium battery powered product was $$$$$. She brought it back with her and the battery showed as 80% charged (but the dock was out of juice).
I attempted to charge it normally, and nothing would charge, the tablet kept losing charge. I then attempted to charge just the tablet with the wall wart, and it would not charge. I tried a cold boot- no change. I tried turning off the tablet and charging it via the usb port of my powerbook overnight, and it did charge (not completely) and I then tried to finish charging it with the wall wart. It would not take a further charge. I am now attempting to bring it to a full charge via the usb port.
I tried charging the keyboard/dock via the usb port of the powerbook overnight, and it did not seem to charge. The keyboard will input to the tablet when connected, though, but there is no indication that the dock battery is active at all.
At this point, I am at a loss as to how to proceed. I suspect that the battery died for lack of a charge for such a long time (end of November to January 12) and that it must be replaced, but I am eager for some feedback from more experienced hands.
I also want to get it up and running on lollipop, but that will have to wait until this is resolved.
TIA!

Wallwart: How do you know it is good? Is it original Asus? Most usb chargers put out 5v, this tablet needs 15v. If you charge via PC USB port it's 5v, called a trickle charge and takes forever. Not even LEDs come on although it charges very slowly.
I suspect the wallwart or - if the cable is not original - the USB cable (even if it works with other devices).

"No indication" meaning you do not see the dock battery icon in the notification bar?
By design the tablet gets charged first, then the dock battery. If you do this at 5V, you'll wait 'til kingdom comes...

I see little point in that, under the circumstances. I have charged the table 100% via the usb cable, I will see if it now accepts a charge from the wallwart.

It won't. Not from a wallwart for an iPhone. You need a charger that outputs 15v.
If your battery icon doesn't show (even if it's empty) you either have a problem in the dock connector or the battery is totally dead. I think you'll find instructions to replace it on ifixit.com

the wallwart was the Asus one that I charged the iphone with (not the iphone one), that is how I tested it. the iphone supposedly draws 12W, BTW
