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.

So I am eagerly awaiting S-Off and flashing new ROMS/kernels/radios and I started to think about how slow my Rezound seems to charge. I know that the Thunderbolt had some kernels that included fast charge capability. Just think of the extra juice we can get in a short amount of time with FastCharge, UnderVolt/UnderClock, and more precise power management.
Does anyone know if this is in the works for the Rezound?
My Rezound charges up pretty fast, especially compared to my Droid Charge.

if your charging on USB it wont be giving the phone full power, to remedy this get a spare cable and disconnect the data so only the power is working
not sure if it works on the computer, but in my car it definitely worked
yeah definitely do a search for USB AC Charging. You can take those car chargers and wall chargers that don't give you the full 1A and do a quick solder job on them to make them work. I just did it with two of mine and it works great. Battery info now says Charging (AC) instead of charging (USB) and they both pull north of +700mA while charging instead of ~+300mA when on regular USB.
Yeah they called it the charge cause its always on the charger

i did that. opened one up and clipped the green & white data cables. the phone still says "charging usb" though and doesn't seem to charge much faster...
Yea, I have tried every possible method of grounding out the data pins. I currently have my phone connected to a computer power supply I converted to a desktop supply with 4 USB charging ports. It can supply up to 13A if the device needs it. The data pins are all shorted and the housings grounded. The phone still says USB Charging....It does seem to pull more current and does seem to be charging faster.
I know that there is some hardware limit on the charging current, but with an SBC kernel (please someone make one...) I think that this bug will be fixed. I am going to try the Trickle Charge technique from previous HTC phones to get a full 100% charge. I will let you all know how it goes.
Or ...
Fast charging is built in ...
... turn off your phone when charging, and use a 1A charger.
DONE.

So I tested this idea that Fast Charging is "built-in", I used a usb cable that I split connected through an Ammeter to test how much current the phone was drawing from the charger in the one and off state. From my tests I found that my phone, no matter what the state does not draw more than 400mA from the supply. My charger is capable of supplying up to 13A to the four usb ports I installed. I also tested this with the HTC stock charger rated at 1A. This had the same results. I think that there is a hardware/software limit built in.
Just to be clear and justify its place in Dev, this thread is asking if there are any developers out there who are working on an SBC (Superior Battery Charging) Kernel for the Rezound. I fully understand the workings of power supplies (I'm an Electrical Engineer) and am just trying to see if anyone is working on this.
And it still belongs in General. That doesn't justify it. If YOU developed a Kernel, or were posting it, then it could be posted here. Questions, suggestions, complaints, ideas, etc belong in General.
Not sure accurate battery monitor widgets are, but mine has shown upwards of 850mah on charging and over 700 on draw (never saw that on my thunderbolt).
It does seem to slow down as it gets close to full (over 90%), then I never get more than 200mah charge.
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'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.
Hey there.
I'm looking at this: http://www.newtrent.com/store/ipad-external-battery/ipad-battery-imp100p.html
But I want to know if the evo can handle charging from a 2amp output. the wall wart that comes with it is only 1 amp and i dont want to mess anything up.
thanks
The phone will only charge as fast as it's charging circuit allows. 2A is just the max that charger will output.
Think of it like this, when charging a device, the device is PULLING the current it wants (as long as the charger can give it that much), the charger is NOT PUSHING it to the device.

By that theory the phone should stop charging when the battery is full, which is not the case because it continues to pull juice and best up.
Did you mean that the phone pulls as much as it can? That would make more sense in my opinion.
Once the battery is charged the phone bypasses the battery, and pulls power to run off of.

I would like to find a high output charger that is compatible with the Atrix. I know that some phones will limit the charging rate with unofficial chargers but I do not know about the Atrix. What rapid chargers have you had success with?
Sent from my MB860 using xda app-developers app
If by that you mean a charger that you connect to the phone, I don't think that will work. If you really want to charge your battery quickly, you will very likely need an external rapid charger (so you take the battery out, put it in the charger, then when it's charged put it back in the phone). However be aware that rapid charging usually comes with a price - by charging the battery quicker you shorten the overal lifespan of the battery.

It all depends on the mA Number on the charger. Lookout for 1A at least and you ahoul be fine

No, it wont.
I use my TouchPad's charger putting out 2A, it works just fine. I use it for my bluetooth, phone, touchpad and kindle. I use it because it's convenient, one plug/wire for all devices.
A device will NOT charge any faster or get damaged by making more amps AVAILABLE at the source. A device will ONLY draw however many amps it needs, not more. This is the reason why you can replace a 100w bulbs with 60w or 13w CFL and not have them burn out. The voltage remains same, just draws less current (amps).
Like ravilov said, you'll needs something external. Even then I'm skeptical. The faster you charge a battery, the faster it will drain, at least with our type of battery.

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.
