Hello all,
So I just bought a new charger (just a wall charger) and now when I plug my TB in, the screen does not respond to anything! I have to take the plug out to work my screen. It is completely unresponsive (regardless of where I'm at on the screen) while charging. As soon as I unplug it, it's fine.
Any ideas?
Where did you buy the charger from? Some crappy no-name/ebay/cheap chargers do that because they are crap. I had bought a cheap charger for my HTC Touch Pro 2 and that same thing happened, used the regular charger, no problems at all.
I know when I used the charger and cable that came with the thunderbolt, it used to become laggy or less responsive. Not terrible, but I could notice it. It was like all the memory was tied up. It doesn't do it anymore though. I rarely use the original cable and charger anyways.

Indeed. The cheap $1.00 chargers may also harm your battery.

Today I tried to charge my phone at work using my original.al charger that I always use and while it was plugged in, the screen wouldn't respond at all. I thought the phone was the problem but I later troubleshot it to low voltage from the extension cord, not my charger.
There are in fact quite a few micro-usb chargers that cause the screen to become unresponsive when plugged in.. This doesn't necessarily mean that the charger is crap, but it's best to use your manufacturer-approved (oem) chargers whenever possible. I work in wireless, and although our supplier is reputable, their generic chargers don't work well with the Atrix & a few other smartphones. I use them only when necessary, but do your phone a favor & stick to manufacturer chargers.
I had this problem, when I use a properly grounded surge protector the problem doesn't happen any more. It also happens to me when I charge out of my old macbook pro which tends to have a 'staticy' feel to it.

You're two months late with your incorrect post. There's a well defined standard for USB chargers, which the TB follows. Non-OEM ones work every bit as well as the HTC one as long as they, too, follow the standard and provide clean power.

Sorry my timing bothered you I was just browsing around for info about the touchscreen issues i've seen. I'm well aware of the standard, 5 +/- 0.25 volts 500–900 mA, and they all seem to charge perfectly well but certain phone/charger combos cause some screens to lag & I just wondered why. For example the motorola adapters all seem to be 5.1 volts @ 850mA, whereas samsung adapters are 5.0 volts @ 700 mA, and the samsungs charge fine on our standard 5/500's while the moto's lag.

It's not clear where the "500-900 mA" and "standard 5/500" figures you give come from. Neither is from the USB Battery Charging Specification.
The spec supports up to a 1.5 A current from a Dedicated Charging Port. The HTC charger is rated at 1 A, and it seems the TB will use all of it. I've seen charging rates of 800 mA, with the phone also running screen, GPS, and more.
Cheap ones, regardless of output, may be poorly filtered with a significant AC component. Those are the ones which will really cause problems.
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...
Well I'm little confusing now .
I have 2 charges.
One with out 5v 2000mah
Two with out 5v 10000mah
I noticed by my self but I need to be sure, big cables delays charge?
Before new systems, like ics and others updates on HTC Systems.
I always charged my phones with 1A.
Now even with 2A charger, some times my phone does not charge. Including some times if I use phone while charging battery decreases.
Maybe it is happening cause of my big cables?
What Is the influence of cables on wall charges?
Roms got influencing the charge time?

Actually out of the only 3 charging options I have the walk charging is the longest. Will reviece full charge in
3 hours but via computer about 7 and just over that for ps3. Surely isn't wall charging always meant to be the most efficient way? When you said big cable, how long? Is it a USB extender? If so I'd say its the cable having problems, generally at the point of transfer from the original USB cable to the extended one.

Well, longer cables means more resistance. Ohm's law says higher resistance, lower voyage and current. Longer cables could explain it in theory, but unless the cable is like 100 feet, I wouldn't be too worried.
Not sure where the issue lies.
Well, it's as simple as this, if you connect to a PC, the current through the USB cable is lesser (500-800mA). This means it will take a longer time to charge the device.
Now, for HTC standard wall socket charger, the output is 1A.
There are chargers that will definitely charge your phone faster, but it wouldn't be recommended as it will heat up the battery.
Now, as far as cables go, length isn't that important if we are talking about something less than 2-3 meters. But if you use an extension, there will be some current loss and also, if the extension quality isn't good enough, it will carry lesser current & take longer to charge your phone.
Also, it would be a good idea to leave your phone for a 5 hour charge on the standard HTC charger and then re-calibrate your battery. Often, a fresh ROM install may not give you the correct battery readings. So, charge to 100% and re-calibrate by flushing the battery stats bin file.
Well, the cables that i use is with more or less 4 meters.

I think that one of the cables you use is bust then. It is true that longer the cable the increased reistance but its not even noticeable. Try experimenting with different cables and to see which one is deffective.

One of the things I loved most about my Nexus 4 was just how quickly it charged. And unlike my SGSII before it, it could even gain a charge while being actively used for Waze. Really great.
With the 5 I'm back to where I was. And thanks to tools I picked up during the 4, I'm able to see why more easily. Seems on the exact same chargers I used my 4 on, I'm easily pulling 400+mA less than the 4 did from the same device and same cable.
I haven't had time to draw a correlation yet, but last night at home on a multi-out adapter from Monoprice I was able to pull over 1200mA which is more than I've ever seen ANY of my devices pull before. But today, on the same model at my office, but with a different cable, I'm pulling around 200mA. Same as what I was getting in my car, which would frequently dip into the negatives, and that was WITHOUT Waze running. Also of note, in ALL of these locations it's being listed as "USB plugged" instead of "AC plugged." I'd say that accounts for the difference there, but the 1200mA draw was listed the same way, so I doubt it.
So, has anyone else noticed this yet and found any correlations between devices, cables, etc., so we can figure this out? Using more power than it takes in will not be something I can survive with and will definitely make this phone a less-than-ideal upgrade over the 4 in the battery life department. But it's pretty clear it's not impossible to get a good charge.
(and yes, before anyone asks, all of my adapters have jacks with a minimum of 1A out, and each also has a 2.1A port. Surprisingly, unlike my 4 which tended to draw LESS power from the 2.1A port, the 5 appears to be unconcerned by the difference, pulling the same poor number from both)
Yes, i agree with you. I just check today, charging my phone from the pc and it seems fast charge isn't doing its thing.

Well, I haven't even dared test it from a PC yet. All I can say is from wall warts and car chargers it's terrible. I can't imagine how bad it is from the limited PC ports. Although it's probably exactly the same, since it seems to be identifying all my wall outlets as USB connections.

Not too surprising. I've read other reports that it charges nice and fast with the stock charger, which is likely the same as the G2 charger since they share most of the same hardware. But that doesn't help with car charging or those of us who've consolidated into multi-port chargers.
When I get home I'm going to mix and match some cables and devices and try to narrow in a bit more. This sounds like the Nexus 7 (2012) goose chase all over again.
The USB/AC detection is done with a definied resistance. Some chargers don't meet those exact resistances (cheap resistors have a big tolerance) -> the phone detects it as USB.
The cable can make big difference, I've tested several different cables on the N4 once, charging rate was between 600mA and ~1100mA (which should be the max) on the same charger.
Maybe the resistance in the charger is right inside the resistance tolerance, so the slight difference in resistance between the cables is enough.
Since the N4 most probably uses a different charge IC than the N5 (I haven't checked tho), it could be that the N4 had a wider tolerance than the N5.
What should help are those charge cables , the one I'm using from Porta Pow can only be used for charging therefore ignoring the charger resistance -> phone should always detect it as AC(even on a PC). Another good thing about those cables is the big wire diameter. Or a kernel where you can force AC charging regardless of the actual source.("fast charge")
That all sounds pretty logical. Considering I got much better results with the Monoprice premium cables I used last night (which oddly, are much THINNER than the cheaper ones), I'm going to experiment with those this evening and see if that makes all the difference.
As for kernels, I'm not planning to root this one if I can help it. I managed to get through the life of my 4 without rooting, too. I know it's heresy on XDA not to root, and until I got Nexus devices I would have agreed. But since stock Jelly Bean I haven't felt that burning need to "take back" control of my phone. I seem to already have plenty.
I observed the same inconsistencies with the N5's charging behavior and did some qualitative tests. I've attached a screenshot with my findings.
The phone is clearly capable of charging rapidly. My primary focus is getting a high current off the car charger. Is there a way to force AC charging mode vs. USB charging, or should I focus on more quality cables / adapters?
Just did some additional testing of my own and found some interesting results. I didn't take perfect notes, but here's what I got:
With the Monoprice 4-port Wall Charger 2.1A 8856:
Cheap Monoprice cable: bad charging, fluctuating between -80A and 200A.
Cheap unknown cable: same as above.
Monoprice premium 3ft cable: 900-1200A.
Monoprice premium 6ft cable: 700-900A.
With the Monoprice 1A car charger 6765:
Bad charging with all cables tried.
With the Monoprice 2.1A car charger 8858:
Bad charging with all cables tried, with exception of Monoprice premium 3ft cable which had same low end, but occasionally bumped over 300A.
With 3.1 (split between two ports) charger purchased on Amazon (my standby for my Nexus 4:
Bad charging with all cables tried.
With Monoprice 2-port USB Car Charger 3.1A 10071:
Cheap Monoprice cable: Bad charging
Cheap unknown cable: Bad charging
Monoprice premium 3ft cable: 700-900A
So it looks like high-end Monoprice paired with high-end Monoprice pays off. Unfortunately there's a rather serious catch with model 10071: it KILLS GPS. At least it did on my Nexus 4, and other reviews reported it as well. I can't be certain yet about it on the 5, but the little experimenting I did in the parking lot showed some anomalies I didn't like. Which means I apparently get to choose between GPS killing my battery, or charging my battery killing my GPS.
Also tried Nexus 7 2012 charger with its own cable and got bad charging, too.

There's a pattern obviously, the 6ft to 3ft drop seems high but is ok I guess.
I've never seen such a picky device when it comes down to charging, usually it just works as expected ^^
Have you tried your cables on the carger it came with ? Or the cable it came with on your other cargers ?
Is there something with "AWG" written on your cables ?
@random_dgp: Well you basically have 2 choices: get a kernel with (force) fast charge support (don't know if there is one yet) or get a charger/cable combo which works.
If you're planning on rooting your N5 anyway I would go for the kernel way I guess, since the charger and the cable are fine most probably, they just aren't in the specs the N5 requires.

The first-gen Nexus 7 was at least this bad. Actually its biggest problem was it refused to even ADMIT it was charging (even though it was) off of most devices. In fact everything I just listed it would claim wasn't even connected to it. A few hours later it was full, but it refused to recognize it. 4.2 fixed that, but it was still slow off of most devices. This at least admits it's being charged, but barely is.
And no, I haven't tried the stock charger yet. I guess I will, but it's not a high priority since it doesn't cover my issues.

i dont know if you're making this up, or if i have a defective nexus 4 lol
before i optimized my N4 i was getting about 4-5 hours of screen time, but it took at least 3 full hours to charge. that charge time to usage time ratio was killing me.
i am having much much much better results with my N5. i have no reason to charge it through a USB port on the computer(are you using an USB 1.0 port or something?), but charging it with the charger that it came with, i get a full charge in about 2 hours.
my N5 will charge a tiny bit over 1% per minute(while on or off), until it gets to 80% and then it charges at about .5% per minute or something
if you're getting the same charge times on the wall charger then i think you might have a defective charger/device. testing this will also be a good way to find out if it's just a slow usb port too

The problem he's having isn't about a computer USB port at all, the problem is that the N5 thinks it's plugged in a computer and limits the current to 500mA to meet the USB specs (and don't blow up some usb ports without a fuse somewhere) but in reality it's plugged in a wall charger.
His phone should be fine since it's working as expected on some carger/cable combos.
Btw. the N5 isn't pulling more current than the N4(both 1,2A), so it should charge almost exactly as fast/slow as the N4. It should even be a bit slower since the battery is slightly bigger I think.

I'm simply using the app Battery Monitor Widget. Really handy tool that solved some problems for me on the 4 with some weird charging situations. While I'm sure it's not insanely precise, it reflects my draining or charging rate well enough to show me what's going on.

I think you're missing the fact that I'm comparing it directly to how well these same devices charged the 4. So they're clearly not defective so much as the 5's requirements have changed completely. And USB 1.0 (I think you mean 1.1) isn't relevant here, as I'm not charging off a computer, I'm charging off a wall and/or car adapter. But sounds like we had very different experiences with the 4. I could charge my 4 off my Monoprice pocket battery in crazy fast time, and my phone was always full by the time I reached my destination in the car, even with Waze running (once I figured out I couldn't use the long cable I was using initially).

Exactly. That's why I was surprised. There's no way it SHOULD be this much slower. Yes, I can see percentage adjusting slightly for the larger battery, but that's why I'm going by mA input instead, and my 4 was getting WAY better in the car. Although I don't think it ever got the 1.2 I'm getting with the Monoprice wall combo, so THAT's impressive. Now if I can just get that in my car without the RF interference and I can call it a day.

Oops, multiple responses and replied to incorrect one, but really if your recharge rate is that much lower v. n4 I'd say that your chargers or n5 are defective. It's going to take longer to charge the n5 obviously, and I have no idea what the max draw either can achieve as I've been strictly using inductive charging w/max 1A supply(as per Qi spec)... n5 takes longer to charge than n4, but thats to be expected by batt cap(and wear(decreased cap) of n4 batt)...
Subjectively, the n5 takes longer to charge, but not that much longer that I've noticed, again batt cap, etc. so...
Both USB/AC adapter chargers I know supply a max of 1.2A...
...(from last so) ask for a replacement n5, after they've been replacing them for a single dead pixel...

Neither I think, we don't need any mA values to see that something is wrong, android is telling us that it thinks that it's connected to a usb port while it isn't.
Of course if we would want to measure exact mA values we would need a different equipment, for cable comparisions in order to see a tendency, the values from the charge IC should be good enough.(IMO)

Well it looks like the N5 has a very low tolerance for AC/USB detection, I'm sure that neither his chargers or Phone are defective, the chargers just aren't 100%in the spec which is obviously enough. I'm sure that the stock charger would be fine.

It's going to take longer to charge the n5 obviously, and I have no idea what the max draw either can achieve as I've been strictly using inductive charging w/max 1A supply(as per Qi spec)... n5 takes longer to charge than n4, but thats to be expected by batt cap(and wear(decreased cap) of n4 batt)...

Clearly neither is the case from my testing. The N5 charges beautifully off of the right combination of chargers, and all of those chargers charged the N4 beautifully. Neither is defective, but the N5 apparently has a different tolerance requirement than the N4.
Really, as opposed to anything being defective, it sounds more like a design flaw in the N5. It's WAY too picky about its power sources.
Mine charged REALLY slow the first day and that night. It also drained really quickly during that same time. I am now on my third day and it has long battery life plus it charged about 20% in 30 minutes on a car charger. Seems quicker than my S3.
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.

Get in touch with the retailer you got it from and ask for them to provide you with a proper charger, as a compensation

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.
