hello would like to know which is more convenient to charge the battery on or off the Atrix and benefits of each loading mode
Thx

Atrix on and sleep/idle wont charge as fast as of because of things running CPU load.
Atrix with no wifi, and bt on, and normal sync. Its taking mv's per second vs off where its able to gain the same charge rate while off. ( bare minimum resources used)
if you want to know what is better for your phone, I think it's the same.
As Ciloteille said, if your phone is on, it will take more time to load, that all for me
It's better for battery to charge slowly using USB from PC. Also, for battery is better to reduce heat. For example if you charge and play games, processor and batter will produce more heat.

Can u explain any on why its better to charge of a PC USB? Is the lower voltage producing less heat the reason or is the slower charge more efficient for another reason?

Basically for every battery is better to charge slowly because chemical process is less aggressive and in the same time produce less heat. PC USB can not provide enough current as charger.
I recommend to read this article How to Prolong Lithium-based Batteries .
PC USB is 5volt correct? Were as most wall charger or car charger is 12 volt?

PC USB is 5V but charger is also about 5V. Difference is that PC USB 2.0 can provide 500mA and chargers more. For example Motorola charger provide 5,1V and 850mA. That's way charger charge battery faster. Some charger could provide 1000mA or more.

Ya that what i was just looking at. Basically what i am gathering from your info and that article is most chargers are designed to fill the battery fast, but what you reall want to do is a slow almost trickel charge like with a car battery were a low steady voltage and amperage is applied
Chargers are designed for fast charging just because users wish to charge battery faster is possible. They don't care about battery. Anyway modern battery will last longer than ordinary possession of the phone.
mmmmm and then I noticed that when you charge the battery with the phone off, it will download more slowly than when I load it on

Hi
X10 is my first touch cell phone.
When battery is 30% i put it on charging it start Discharging till 0% and then phone go to shutdown. After sometime it start but take too long to charge 30% of the battery.
Is it normal for X10..???
Please help me if anyone know about this.
Thanks
Are you charging via usb or by ac adapter? usb charging does not seem to provide enough juice to charge the battery.

from my experience with mine is up to 10% or 15% im not sure. theres a blinking red then after that its solid green..but charging is really slow on this
im usb charging at play around with it and its actually draining battery
not sure if this is normal but thats what im experience and most of the aftermarket charger out there doesnt work very well with this device
You need a charger with at least 850mA capacity to be able to charge the phone normally. USB charging from computer is slow as it is just 500mA and if you are using the phone for heavy stuff like watching video it may actually lower battery percentage instead topping it up.
Most aftermarket generic USB chargers are 500-550mA especially car adapters, some are even lower.. Make sure you get properly rated charger for this phone to avoid any issues.
Sarcasm, haha laugh a little.
But really, do you guys notice that it takes a long time for the battery to charge?
I think when available, I'll buy a bunch of batteries just to have handy.
well the battery is 1500mAh the nexus charged pretty quickly but it was 1400mAh i am not sure how much difference 100mAh will make on charging the battery but that could be a possibility.
Charging with the computer will always be slower, if that's what you're using.
I wonder if its the charger. The provided charger has an output rating of 0.7A. I know some microusb chargers I have seen are rated as high as 1.0A. That could be the difference.

Interesting...that could be. However, maybe it's 0.7A for a reason? Perhaps the battery needs to have it at that "flow rate." ???
We did get a different charger over the i9000, they had a separate USB cable and microUSB wall charger. We obviously don't have that setup.
Some phones have Li-Pol batteries and they have to charge differently. This could be why it's taking so long to recharge.
check a tmobile store or website for the new portable micro usb charger. charges your phone on the go and recharges itself via a usb charger the vibrant ships with or your computer. i got mine and was a lifesaver the other night when i needed to leave my house with 10% charged.
I hate saying this, but: I literally LOL'd from the title of this thread.
I completely agree. Charging takes fuggin' forever. My guess would be that turning the device off helps speed this up, tremendously. But of course, who wants to do that?
That said, battery life has been impressively long, provided you turn off Samsung's widgets. :/

That would be a huge design oversight if a generic charger caused problems with the battery. I'm sure Samsung thought about the user charging with a generic charger.
Mine charges pretty fast I'm using the usb that came with the moto cliq

How fast is fast, iceshinobi?
I have conditioned my battery twice and going from empty with the phone off and pluged into the wall not via usb-pc, took me over 4hrs each time.
If the charger is 0.7 going to a 1.0 would be a huge improvement. The only worry would be the extra heat and problems that might cause. With NiMH batteries quick charging is preferable to slow charging, is this the same for Li-ion?
came here for insight as well, woke up at like 5am, phone was almost dead, 10% battery or so
turned it off, plugged it in to the wall charger and it is now 8am and it is maybe 60-70% charged
what the hell?
with my g1 turned off i can go from 0 to 100% charge in like an hour or so using a USB port. now i know the battery is smaller but c'mon... this is ridiculous.
Could it be that the phone just has to break in? When I first got G1 it would take about 4 hours to charge I remember, now a year and a half later I can get it to 80-90 percent in 1 and a half.
The computer USB standard is 100 to 500 milliamp, the USB walloulet adapter (charger) Is 700 milliamp, our batteries are 1500 milliamp and that's why.
USB cables have a certain standards witch includes voltage and current standards.
If you want a fast charger look for a hard wired 1000-1200 milliamp charger with a micro USB connector on ebay.

Interesting...having a 1000+ milliamp charger shouldn't cause heat issues would it for pumping in more juice at a higher rate?
Do you think it would be safe to charge the evo with a 2.1 amp car charger? I found one on ebay that says its made for the iPad but I would love a faster charge on my epic.
In general, the slower you charge the battery, the longer it will last. The effect is pretty significant.
I don't know if that much current is safe.

It's more complicated than that. Just because the charger is able to provide 2.1A doesn't mean the phone will actually draw that much current.
The charge control circuitry is built into the phone. You are just providing a +5V rail as the charging power source via a standard USB connection. There is no charge control inherent in USB itself.

It will only pull as much as it needs. I use higher amp output chargers and it's not a problem. It will charge faster, regardless of what you use, if you turn the phone off.

this is true, but the effect is not that significant, coming from using lithium packs in rc helicopers and cars, the battery will likely be obsolete before you kill it and the batteries aren't that expensive.

do you have a link and is there a wall charger too? I run a remote desktop app and it destroys the battery, even with the 1 amp charger going the battery just gets lower and lower.

It could be due to the usb micro charging standards... Many chargers do not adhere to the standard, and this may cause some of the newer phones (droid X, galaxy S phones) not to charge at full power. Most older phones simply did not care, and would use all the amperage they could get their hands on.
Basically, if the D+ and D- pins of the USB cable are not shorted, then the device will draw minimal power from the +5v rail. It is probably drawing <500 mah, and could even be drawing as little as 100 mah from the charger.
Getting a proper 1A charger could fix this, but I'd like to test it out myself when I get the chance..
http://www.griffintechnology.com/products/powerduo-for-ipad
These work good. I use the ac one. Only thing is, like some have stated, even when charging when phone is on and using the phone, the battery will still go down. Maybe 2.2 will fix this or a patch.
I'm not going to debate fast vs slow charging. This isn't like debating what is the best charger for AA rechargeable nimh, fast or slow or charging method.
First time Charge your phone using wall charger and completely discharge it and next time charge using usb cable connected to your pc/laptop. Post your results . My battery lasts 30-40% more when I charge using usb connected to laptop.

Weird your computer usb has a much lower voltage output and will take much longer to charge, as the battery will still have the same mAh rating when charged fully it shouldn't have any impact

Yeah I know pc usb charging is slow but it lasts much longer for me. Give it a try
Sent from my X10i using XDA App
doesn´t work for me. Same as wallcharged
So I realized that if I charge my phone using the USB ports on my laptop, the phones batter lasts much longer than if I charged it through the power outlet in the wall.
I didn't take any screenshots because I didn't think of it at the time, but through the laptop I got about 2 days and 14 hours with moderate use and I had 18% battery left.
Through the wall charger, I get about 18 hours with moderate use.
Can anyone else confirm?
Not sure, but i do feel that it charge slower on the USB port of my laptop. Maybe it have something to do with your theory.
Centranly!
USB port can give max 500mA but the wall charger can supply with 700mA (+40%!!!)
I have a charge-only cable that charges over my MBP's USB faster than any AC adapter I've tried. Charges last about the same regardless of power source though...

USB 2.0 will provide up to 500mA while USB 3.0 can provide 800mA. Stock Atrix wall charger I have is 850mA.
How do you verify what mA you're using? Is there a good tool for that?

IIRC, these are minimum specs for the standards. Could be wrong, but I believe that true output varies card to card/port to port.

I've heard this theory before, but didn't see noticeable difference on my phone to back this claim.
I do agree with OP that charging the phone connected to a laptop USB port would give longer battery life. I have noticed this on several occasions already. I also agree the charge process would be much slower. With my phone, with 5% charge or less, the battery icon randomly doesn't animate while being charged.
That a side, I'm also sure something is broken in Atrix design, be it hardware, battery, or both but something is not right. I can't even charge my phone from a power point with the supplied cable and the plug [UK].
I know Motorola won't admit neither fix this problem in Gingerbread but might do, quietly, in ICS. One other possibility I can think of is that the supplied plugs are the culprit.
Today i charged the phone from my laptop, and im not feeling any difference at all. Its discharging at my usual pace. :/

Furthermore to my previous post, I have finally found the opportunity to test my phone with a Blackberry charger and it started charging the phone from the power point. That means the Motorola UK plugs I have are broken.
I'm arranging to purchase a Blackberry charger now. Don't want waste my time and money with Motorola anymore.
