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

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

I was excited reading this because my new laptop has a 3.0 port. However, I then remembered that my power brick for my laptop is kick ass and has a USB port that charges devices at 1A anyways. Haha.

So I got it down to 5% and then I plugged it in at around 8pm and at 11pm it was at 100%. Not bad, not great but seems about right. Now my question is I see a notification that battery is fully charged and to unplug charger but Im going to bed soon and am going to leave it plugged over night. Is this risking the battery in any way?

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.
Hi,
I was wondering if it will be OK to use a 2A & 5V with Evo 3D. Evo 3D dies after a while when it's connected to HDMI Dock. Their is not enough current to keep it alive. And with a 2A 5V charger will also charge my Samsung Galaxy Tab 10.1.
Thanks.

If I remember my physics correctly, you should be OK because the phone will only use the amperage that it needs.

I a little worried about it might heat and might adversely affect the life of phone. As long as it's not too bad, I am fine with it. I plan to leave my phone on dock, so, I will be connected to 2A charger with extended period of time but then their should be some safe guard implemented by HTC to handle such scenarios.

I've actually heard from friends that their phones got hot when they did not provide enough amps. Using a 500mA charger for the 3d got their phone piping hot for some reason.

I am not sure I understand you. You mean to say even an extra 500mA, that is 1.5A total, would get phone hot. HTC 3D requires at least 1A of current, so, it won't charge with a 500mA charger.

Not true. The phone will charge with any amperage. I have an old car charger that only puts out 200mA, and it charges just fine. Obviously it doesn't charge very fast, but it's enough to keep the phone topped off when I need it.

No, and as stated above, it will not hurt the phone either. The Evo will draw at max around 1 amp. You can use a 2 amp charger, but the phone will not charge any faster, as it will only draw 1 amp. I use my tablet charger once in a while, which is also 2 amps, and can confirm the phone is only drawing a little over 1 amp from it.
When I connect phone with TV through HDMI dock. Phone draws more power than 1A charger supplies. Will 2A charger be able to provide that extra charge, so, phone wouldn't die or depleted of power?
I don't mind heating as long as it's not frying phone chip anytime soon.

If the charger is rated higher than one amp you should be alright, but I wouldn't recommend using one rated lower than 1 amp (or 500mA for usb/car chargers)
I just fried a charger not too long ago because I plugged my touchpad into it and it was only rated at half what that draws.
I ask because I know that my bionic could pull about 1.5Ah. So is it a kernel limitation, or something else? I can pull 1A now, but nothing more. I know it's not much, but it would be nice to be able to get a little more juice from a 30 min charge.

I was using a 2.1 Ah charger for an ipad. The bionic would only pull 1.5Ah from it though. My Rezound, and when I had the tbolt, will/would only pull 1A. That's why I wasn't sure if it was hardware or kernel support limitations.
It's probably a kernel limitation, but it could be hardware. The thing to be careful with fast charging is that it really heats up the battery, and hot batter = shortened life. It could conscious decision by HTC to protect the battery.

After kernel source drops, devs can tweak the kernel to permit faster charging than the stock kernel. That's what happened on the Incredible. Everybody included a fast-charge kernel in ROMs.

^^ yep chad did it with the INC im sure he can do it for the rez once source is out.
I have a dual usb car charger. One side is 1A, and the other 2A. Interesting when I plug the Rezound into the 1A side it says charging AC, but the 2A side says charging USB. But yet the 2A side WILL charge my ipad and Nook Color. I had Chad's kernel with the Dinc, but I find on the rezound AC charging is fast enough for me....as long as the phone recognizes it as AC charging.

Certain charging cables are charging only and no data they always return as AC charging on your phones. It seems to be hit or miss with data cables.
It might be possible but doesn't solely depend on the wall charger or car charger. The wall and car chargers are not actually chargers. The a/c charger is composed of a transformer, rectifier, and dc-dc converter typically. The car charger is just a dc-dc converter. The phone has the actual charger ic or a pmic that charges the battery based on the current supplied and what the micro-processor tells it to do. There are many other factors as well, but it might be possible (depending on which pmic the manufacturer used) to change what the processor tells the ic to charge at.
Just curious if there is an app or something similar that would show how many amps are being provided when charging through a wall charger/USB powered hub? The reason I ask is that I'm thinking of buying a powered USB 3.0 Hub. The adapter that came with our phone says it's 2 Amp, so I am assuming our phone can pull 2 amps for charging. Just wanted to verify in some way that a 2 Amp dedicated port would really work for this phone.

When I get home, I'll download the kernel source and see if I can find out how much power it draws during charging. I doubt however, that it will draw 2A during charging as most chargers are rated to supply more power than the phone will accept.
Yeah, 2A seems like that could melt a battery charging that fast. Someone sent me a private message and told me to try CurrentWidget. I threw that on the phone and it registers as 1A while charging. But it appears like the widget doesn't break it down with decimals. For instance it could be charging with 1.8A and wouldn't know it. I put it in a standard USB port and it reported as charging with 0 Amps but the battery was indeed charging.
I took a quick look at the N7100 (International Note 2) source posted on Github by CM and it looks like AC charger is 650mA, USB is 450mA. It's a little hard to tell what exactly it's using for charging, so I'll try to verify that when I get home and have a chance to take a better look.

A 3100mAh Lithium Ion battery can easily handle a full 2A charge rate. The ideal charge profile for Lithium Ion is a CC/CV profile, starts at constant current between like 3V and 4V, which most LI batters can take a rate of 1C, meaning it can handle a charge rate of 3.1A, recommended charge rate to achieve the most possible charge/discharge cycles is usually 0.2C so for a 3100mAh battery that would be 620mA. Once the charge gets to the correct voltage it gets to constant voltage and charges until termination current usually in the 100mA range. So yes, it can handle a 2A charge no problem.
Hey there. I very much appreciate that breakdown. Makes me wonder why they dropped the amps so much during charge.

If this is true (first time I've seen this anywhere), that would line up great with the 650mA max charge rate I found. Also, I downloaded the VZW source, and it doesn't look to significantly different from the N7100 source, at least as far as the charger stuff is concerned, so I would say they both probably have a max charge rate of 650mA.
I appreciate the info and time you both put into this. I guess it means a 2A usb port will be slight overkill. Even changing the charge rate to a higher value seems to indicate a lower battery life. Makes you wonder how apple did it's math for the ipads charge rate. The battery must be huge to accommodate a 1.1A charge rate. Or they are sacrificing battery life for fast charging.
Wont the kernel dictate the charge rate no matter what the charger is rated at?
If the kernel is set for a charge rate of 650mA (0.650A), then why does the Note 2 have a more powerful 2A wall charger, while the GS3 has a 1A wall charger.

The original nook color 7" came with a 2A wall charger and that was 2 years ago... both my note 2 and nook color charge about the same rate (quick to 99% and slow to 100). The charger is probably cheaper to make at 2A rather than anything and plus it could be used to charge future devices. Also if you used a 1A charger to charge the note it might possibly get warm/hot from running at near full capacity.
Im using my OLD blackberry 700mA wall charger to charge the phone at night while im sleeping. No problems with heat.
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.
