Just wondering, I bought two JetStreams last week and both of them take a while to charge; I would say over 8 hours. My previous tablet would get fully charged in less than 4 hours.
I love this tablet and besides the usb port and audio jack placement that's the only other thing that's bothering me at the moment.

Using the 9V charger that has been provided by HTC, I can charge my tablet in around 3-4 hours - not sure though - will clock it next time I charge.
However if you use a 5V charger which is used by other phones, it will surely take longer.

That's what I suspected, I bought these tablets on ebay and they both came with the smaller 5V chargers. Just wanted to double check, thanks for the reply.
Yea I got a small charger as well from that ebay sale. Using my iPad charger(switched the usb cable). What's weird is after a few minutes on 100% the second I unplugged it could go down to 9x%. I had to leave it for a bit longer for the charge to stick to 100% unplugged.
Well I have tried around 4 or 5 different chargers and with all of them it's taking over 8 hours to fully charge my battery. I don't know what's the deal with this tablet, I bought the OEM genuine charger from eBay and even though it's bigger than the one that came with the device - which is a phone charger; the output voltage is the same 5V.
I tried switching the cable to my girlfriend's iPad charger and it's still taking a while; it's starting to annoy me. Battery life hasn't been an issue though, it lasts over 24 hrs under moderate use - netflix, web browsing, emails, eBook reading...etc. So I don't think it's a bad battery because it holds a charge just fine, it just takes too damn long.
Any ideas, comments or suggestions?
Its not the voltage of the adapter but the output amperage that matters.
The small adapter that came with my ebay JetStream only supplies 200 milliamps (mA) and can take 2 nights to charge fully (i.e., overnight will only charge it to 60%-70%).
As a point of reference, the adapter for my Bluetooth headset is 180 mA.
My BlackBerry charger, which charges my JetStream in a several hours, has an output of 700 mA. Actually, I have never timed it, but it does not take over night to fully charge it.
The AT&T site has a HTC wall charger for the JetStream - does anyone know what the output amperage of the HTC wall charger?
I Have the ATT power cord.
Output 9V, 1.67A
Full charge for me is approx 3 hours, maybe a little more but i've only let my tablet go almost to 0 once.
Hope this helps, Charles
My girlfriend's ipad charger outputs 5v, 2.1A and it still takes a while to charge with that one. All my other chargers are also 5v so i guess im gonna have to get a 9v one to see if i notice any improvement in charging time.

Last post seems to apply to my problem:
It will take about 4 x longer than the OEM for the same amount of charge.
If you operate the Flyer while connected, it might not charge at all, but will discharge at a slower rate.

Yes,your 100% correct. Don't know why the eBay company that shipped these all in the HTC box, didn't put the original charger. I think I'll write to them, although it may not help any.

The beast? I got mine but haven't powered it up yet for charging purposes. There is no light indicator that tells you when its done.
Got mine yesterday and I charged via AC and it took about 3 hours to complete. After letting it drain over night after 8 hours of heavy usage, I'm charging via USB and it's taking forever. With it on and after 2 hours, it was only at 15%. Now turned it off and it's been 3 hours and it looks like 75%. BTW, press the power button once and the screen will show the batter gauge.
you should charge it while turned on and for 6 hours or more for 4-5 cycles. Let it go down to 5% for those 4-5 cycles. Do not let it turn off from lack of power.
That is from instructions I received from a third party battery which had these detailed instruction to maximize capacity. I am sure you will get 1000 different ways but that is what I use and have always had good battery life.

This thing pretty much requires the cable that came with it to charge at full speed. Older MicroUSB cables charge at a much slower rate and are recognized as USB devices when plugged in. It must be because of the higher capacity battery. When you have the right cable plugged in, though, it charges pretty fast.
I'm noticing that even using the wall charger and the USB cable it came with, it's taking about an hour for the Note to charge only 15%. Anyone else noticing this? Is it normal that the first batch of charges takes this long (at that rate it would take 6+ hours to charge from 0-100%)?
My note charges very fast when I use the ac adapter and super slow when I use the us from my computer. About 1.5 hours on the ac and more than 3 hours on my pc's us
Sent from my SAMSUNG-SGH-I717 using XDA App
Its always a good idea to charge using the AC wall adapter. The USB port on a computer usually supplies ~.5A @ 5v to charge the phone, the included Samsung wall charger supplies double that with 1.0A @ 5v. That is the reason you see such a big difference in your charging times.
(Some computers now supply more than .5A through USB, but .5A is most common)
USB3.0 can supply 5.0v @ 950mA to charge, but the kernel isn't set up to take advantage of this, I'll see if I can change that (it would only affect charging while booted)
Just shy of the AC adapter for those of us with USB3 ports

That would be the only use for my USB3.0 ports so far. Have yet to even need to utilize it.
The charger that comes with the Note can charge the battery in 3hours via ac. I wouldn't suggest to charge via usb, just because it's way too slow. Im using my playbook charger to charge my Note, Galaxy Nexus , and my bb 9900. This charger is 1.8a, it nearly charges 2x faster than the regular 1a that comes with most phones. Same thing for my car charger 2a, i even use my ipad charger to charge my iphone 4s and it's way faster!! Use more powerful chargers... Not more than 2a or your device might melt down!!

That's weird. I was under the impression that GS Note only accepts 1.0A of power. Well at least that's what it saids at the back of the phone. I've got an iPad charger that draws out 2.1A, maybe I should give that a try.
In about two hours of charging I went from 8% to 41%. Is anyone else experienceing this issue? I'm using all the cords and plugs given to me for the wall.
I don't have the SGS3 (yet), but my guess is that the battery is so large it takes longer to charge. Keep in mind that it's a 2100MaH battery. Depending on the power that the charger puts out, it could take longer to charge this battery than another phone.
Mine charges fairly quick with stock items.

I agree, the first few cycles might not be too accurate. If you want a faster charger get the HP Touchpad charger, it has 2 amps where as the Samsung one is .75 amps of charging. only $5 on hp website. that's what I use.

Monoprice sells a 2.1 amp 4 usb wall charger as well but it is not as cheap nor do they have free shipping *although atleast in CA I can get a flat rate of 25lbs and under for ~$5 shipping.*
I'm surprised no one has posted the correct answer to this yet. The wall charger Samsung has decided to include with the S3 NA is complete and utter crap. I believe it is .15amp draw. You need to immediately throw it in the trash and buy a new one. It is not a problem with your phone.

My Samsung Charger that came with the phone is 1Amp...charges the device fine. I don't think the 2Amps will make a difference if the charging chip doesn't support it (not saying it doesn't but the SGSII would only charge at 650maH no matter what charger you put it on)
Mine's charging insanely fast with the stock cable. Not sure if it's a good thing because battery life isn't all that amazing on my phone so far.

doesn't that mean each USB port is 0.5 amps?
Anyways if I'm not wrong the amps has to do with what it can supply. Whether the device tries to draw that much power is up to the device.
The stock charger is 5V 1amp.
Even if you use a 2 amp charger it will likely only draw one amp.
Even if it does draw 2 amps that would mean you are increasing the heat associated with more current. Heat is the worst thing for battery life. Its always better to do slow charge unless you're in a hurry. Your battery will last a lot longer that way. Having said that, I think 1 amp is a good compromise for speed and heat.
p.s. computers output 0.5amps per USB slot by default specifications.

-charging started at 1% battery left
-WiFi/sync ON, display OFF
-original 5V/2A charger and cable used
Total charging time: 6h 8min, about 18%/h (between 0% and ~80%).

thats a long time for a 2amp charger
seems to work with my 1amp note charger though
Has anyone look looked in the sysfs to get a better idea of how much power the tablet is actually drawing from the charger? I know the charger is 5v/2a but what is the tablet actually reporting. It is possible that the tablet is incorrectly identifying the charger and only allowing ~1a. It wouldn't be the first time this has happened.
Iam very happy with micro usb charging.

The Note 2 charger is 2 amp so it should charge just as quick
I was around 8% or so, and then I left my N10 to charge overnight (5-6 hours) from the wall charger. Woke up to it fully charged
Had WiFi enabled, sync on, and Asphalt 7 downloading in the background.
I was at 37% at 1:30am, woke up at 7am and it was only at 61%. Given, this was using a staples brand dual USB wall port with my GSIII plugged in as well. I certainly hope they release a pogo charger soon.

i have one for my Note,but wont work on the Nexus 10
so if i get an apple charger or equiivalent from Ebay, the ones with 12W rating 2-2.4A will it chargee my N10 faster than the stock one? im guessing not by much. currently its taking 6-7 hours to charge. and if i forget to charge it over night, then kinda useless next day.
If anyone is looking for an alternative USB to AC charger, get the one from the HP touchpad. It's one of the best ones out, topping garbage like the apple one.

Hi all,
When I use the charger that came with the HTC One my phone charges great, rapid.
But when I use any other charger that I have in my home/office it charges very slow. Even with a 2.1 amp charger!
The charger that comes with the phone has an output of 1 amp.
I've tried multiple other chargers (1 amp and 2.1 amp) and they all trickle charge.
Anyone else noticing this?
Thanks
Joe
I'm using old charges at home and in the office and it did seems slow but had not heard of rapid charge. Will the phone indicate this rapid charge mode? If not, is it real?
I'm getting slow charging even on the stock HTC charger. Not sure how I can enable this rapid charge cause 4+ hours from 0-1% to full is a bit ridiculous.
use orginal charger is best , maybe it has some relationship with your battery life
If anyone is coming from phones with smaller batteries, remember the larger the capacity the long it takes to charge.
I use the cable and charger from my Nexus 7 and it charges fast. Off my USB it is slow.
Real AC chargers have two pins shorted. You can hack a USB to micro USB cable and short the same two pins to enable AC charging with any adapter, wall, USB, or car. Should be pins 3+4, but don't hold me to that.

i've done exactly this, and damned if the One still refuses to draw more than ~500 ma off of anything but the 2.1 A wallwart it came with (i don't have any others to try with). i'm about to dig out an old inverter to see if that will actually work. wish i'd paid more attention to my EE dad when i lived at home; i've gotten a serious crash course in this stuff while trying to get my One to charge in my car, when it's on.
edit: so i got my old inverter out, and spent about 15 minutes testing. i used the 2.0A adapter that came with my Nexus 7 to test, as well as the 3.1A Mediabridge adapter i got here. my phone was at about 45% when i started testing. unplugged, Battery Monitor Widget reported a drain of anywhere between 500ma and 650ma (running Ingress, wifi on). plugged in to the Mediabridge adapter showed, at best, a drain of 50ma. the Nexus adapter plugged in to my inverter charged at a fairly consistent ~120ma. i didn't touch my phone the entire time.
i left my Nexus 7 at work so i can't use it to repeat the test, but i will do so tomorrow. the cable i'm using is this one. i'm not crazy about having a ridiculous DC-AC inverter in my car for my phone, but if that's what i have to do so it can be used and not drain, then so be it. admittedly, i don't really understand these things enough to explain these variations, but i plan on learning ASAP. perhaps somebody else can shed some light on why the device charges different, and how it identifies an AC-USB adapter vs a DC-USB adapter.

Math doesn't support what is happening though. Phone has a 2300mAh battery. The OEM charger outputs 1A (1000mAh)
At most, it should be around 3 hours for full charge, when in fact it is closer to 4-4.5 hours. It's the last 10% that is the issue, it will trickle charge to 100% rather than rapid charge.

Yes, I think that's exactly what the HTC does... I read a pretty good article recently about Li-Ion batteries that talks about how trickle charging is the best for battery life, and it wouldn't surprise me if HTC got a little aggressive the way the this phone charges since we can't swap the battery ourselves.
I'm trying one last car charger, which matches the wattage of my Nexus 7's 5Vdc/2A AC adapter (which I've had the best luck with, when charging the phone while in use): http://www.amazon.com/gp/product/B009TBF7IG/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
If that doesn't work, I'm going to put a 300W inverter in my car with the AC adapters themselves and stop buying stinking DC adapters. This phone clearly pays very close attention to the wattage available from whatever it's plugged in to.

I'm fortunate my car has a built in inverter that I use for charging my phone.

My next car will too, because I can only imagine that power requirements for these devices is going to increase.
That said, I think I have a winner, and instead of retyping my posts, I'll just link to that thread instead: http://forum.xda-developers.com/showpost.php?p=41797839&postcount=6
Since the snap Dragon 600 has fast charging capabilities, why didn't HTC Include it in the kernel??? I've noticed my 2500 mAh note battery charges faster than my 2300 MAH HTC one

Hello
For the first time I let my XTZ drop below 40% battery.
I chargy only with the Sony's cradle since I don't really carry it around.
I get to putting it on charge when it reached 10% battery, but few secconds after it showed charge animation a pop up appeared that battery is low and should be charged. This kept showing every few secconds.
It looked as the charger contacts where not making good connection. So I tried moving it around, checked the contact pins and the lever if it pulls them out and springs where working. It all seamed to work ok. It was late and I had it wet 3-4 hours ago so I just left it off the dock till morning.
When I got up I tried to put it to charge again, but same buggy pop up started to appear...
Now I left to work, set sound off and left it to charge with hopes above 10% it will be ok...
Anyone else experienced this?

Well I have my problem solved lol.
As engineer I don't usually read everything about the spec...
So the charger I used was rated at 2A, industrial quality mind you, while the cradle is actually rated at 1.8A input and 1.8a output...
I tought the cradle is just two wires and some weights, but seems to be more than this.
Anyway the XTZ started to charge fine with the Sony charger at 1.5A.
The tablet also charges faster with the 2A charger, but only from the USB.

I don't think it's the rating of the charger - I had just posted this in the "battery broken?" thread in this forum :

Charged mine for a while this morning in the Sony dock with power on, wifi on, screen off. Like others, I use an iPad charger (2.1A).
The battery went from 11% to 55% in about 2 hours, so about 22% per hour - though I think it slows down as the % gets higher.

I've been using an iPad charger for the last 6 weeks to charge my SXTZ either directly through the USB port or "indirectly" through the Sony docking cradle. I've had no problems - as you can see from the above quote.
By the way (not that it matters) I'm an engineer (electronic) too.
