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.

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.

If this was mentioned before I'm sorry about bringing it up again but with my lack of knowledge on li-ion batteries I figured I'd check with you guys to make sure nothing is amiss here. When I was charging my n1 I noticed the back getting quite warm so I installed spare parts and saw that my battery temp was nearly 38 degrees Celsius.
Is this a bad thing or is it completely normal and I shouldn't think to much of it?
Again I'm sorry for the noob question.
Completely normal.
its normal, the wall charger charges at 1A, while USB charges at 500mA. If you want a faster charge wall charging is the way to go. I use USB because im not in a hurry and high temps are not good for any device (although im not saying you shouldnt use a wall charger, its just my personal preference).
It's normal, mine behaves the same way...

Actually, the battery is designed to be charged optimally at .98 amps. I recall someone saying that charging with the adapter is better for battery life, and charging with the USB cable should be done sparingly.
Cool that's good to hear, I just wanted to be a bit on the cautious side.
uansari1: so it's better for the battery to charge it with the power adapter? Offhand do you know what kind of drawbacks would occur if we were to use the usb cable instead? I'll try to do some research on it a bit later, if using the adapter means keeping the battery healthier I'd be all for it.

What we were told, and this was in the G1 forum, was that the battery life and capacity is maximized when using the charger, and over time if you only charge with the USB cable, the capacity can go down...meaning it loses calibration over time.
Don't worry about the battery getting warm... the phone is designed for it, and so is the battery.
Like many of you guys, I have custom built my own PC. Yeah, it's a little outdated with a Q6600 but it will do for a good year or two more. Good thing I bought a Quad Core. But anyways, getting back to topic, you guys should realize that the Power Output of the front two USB ports are not the same as the USB ports that are in the back. This is a fact as far as my system is concerned. I know because I use a Lacie External drive which will only power on with the rear USB ports.
If you charge the SGS with the included wall charger, it will charge up in about 4 hours. When I leave it on my front USB port, I would wake up in the morning only to find it 60-70 percent full.
PS - I am amazed by the battery of this thing. Here is the break down. I fully charged by 1am. Took it off... then started using it quite a bit till around 3am ish. When I went to bed, the charge was at 72 percent. I work up 6 hours later and guess what, it was at 69 percent. Pretty neat.
The USB 2.0 only requires that a motherboard provides 150mA to a single port (& 500mA to 5 ports). Where as a chargers don't conform to this standard and provides a much higher charge, which charges your battery much quicker.
Only use USB if you have nothing esle.
The wall charger that came with the SGS is a 700mA. I just ordered a 1000mA wall and car charger.
The more I use this phone the more I am amazed by it. The Battery life on this thing is really great. It's already been close to 12 hours (11:30) and the battery is now finally at 49%
I've used this phone quite a bit and the battery held up really well. I used Let's Golf, Navigation, Armored Strike, Calls, Texts, Gmail... Good stuff.

It will do neither.
read this. Gives some basics on Li-ion batteries. link
Essentially these batts can and should be charged at 1C c=capacity. Our batts are 1500mA so we could and should charge at 1500mA.
Slower charging is fine but these batteries rely on circuitry recognizing a drop in voltage to turn the charge off, or down to a lower current as to not damage the battery. If you charge at a higher rate the drop in voltage is more obvious than with a lower voltage and harder to miss thus less chance of an overcharge and battery damage. Added bonus is the battery charges quicker
Over charging is the killer of batteries. Overcharge occurs more from circuitry missing a change in voltage and failing to terminate.
Hope this helps.

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.

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.
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...

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 can see if this was someones first Android, the lack of a micro-USB for data would be frustrating, but I have about 5 of these in my desk drawer and throughout my house and office, so it doesn't bother me.
Also having a fixed cord means you don't pulg some 'slow' cable in and not get any benefits. Out my 8-10 micro USB cables, only 2-3 get a decent charge speed.

If a device that does not do Turbo Charging is connected, the charger should automatically adjust and charge it at regular speed. At least, that's what it is supposed to do. The Turbo Charger is supposed to be the single charger for all types.

I think the reason they made the cable fixed is because a lot of cheaper usb cables use very thin wire gauges. Since this charger puts out a lot of current at varying voltages, it's very possible for a thin cable to overheat easier and catch on fire. And my guess is, they didn't want to take any chances
How do we determine if turbo charger is ongoing? I mean are there any indication? Coz when I plug in the TurboCharger that comes with it, sometimes TurboPower Connected shows at the bottom of the screen, sometimes not. Then when I check it on the Status, it says Charging over USB, not Charging over AC? Could be that my unit is defective? perhaps the charger? or the battery?

You can use a USB voltage/current indicator device to see it directly. I use one that displays voltage and current simultaneously, it cost about $10 on Amazon.
The Qualcomm QC 2.0 (which Motorola terms "TurboPower) spec is 5, 9, 12, and 20 volts, with up to 2 amps plus at each voltage. The QC 2.0 chargers I've tested including the Motorola charger included with the XT1575, range up to 9V and about 2+ A at 9V, with the higher voltage/amperage when battery is discharged to a lower SoC.. Haven't seen 12V or 20V, I think those only come into play when battery is discharged to nearly zero SoC.
Agree the reason the included charger has cable attached may be to ensure adequate wire gage. Too-thin wire will increase voltage drop across cable thus lengthening charge time in higher power modes. But the design here uses higher voltage to keep current down around the same 2A max current of USB 2.0 chargers, so cable heat will not be a problem with any old USB cable.
I will attest to the benefit of QC 2.0. I thought it was a useless gimmick until I started using it. It does effectively compensate for mediocre battery capacity.
My "Turbo Charging" icon displays properly, but doesn't charge very quickly if connected to a cheap extension cord.
Plugged into the wall, the charging Stull doesn't impress me that much

It's defective. Call moto they will replace it for free. Just have to send copy of purchase receipt. Had the same issue.
The charge rate depends on how discharged the battery is when connected to charge.
More discharged (lower SoC, State of Charge) will drive a higher charge rate.
As to the difference between this Motorola TurboPower (aka Qualcomm Quick Charge 2.0), vs. other phones:
I've measured up to 1.4 amps at 5V nominal on other phones, that is about 9 watts charging power. That is max charge rate, with a very discharged battery. As the battery charges up closer to fully charged, the charge rate (power) is reduced. Total charging time from fully discharged to fully charged would be about 4-5 hours, give or take, for a typical cellphone battery.
For comparison, the QC 2.0 measurements I made with the MXPE: Up to 2.2 amps at 9V nominal with a phone battery discharged to about 40-50%. That works out to about 20 watts charging power. As with other Li-Ion battery charging systems, this also declines as the battery approaches fully charged. Total time to charge, from fully discharged to fully charged will be about 2-3 hours, give or take.
So the marketing claims about QC 2.0 are about right: A 75% improvement over conventional charging systems.
The biggest gains come when charging batteries discharged to lower SoC. If you are comparing charge rate/time of batteries discharged to only, say, 70-80%, you will not see as much of a difference with QC 2.0.
I'm not a QC 2.0 marketing shill, mind you. I pretty much ignored it, before buying the phone. But for this phone, QC 2.0 actually does a good job to compensate for the mediocre battery. I can run the battery down to 40-50%, put it on QC 2.0 charger in my car for my 30 minute commute, and it is charged to around 80+% when I arrive at my destination. There are a lot of QC 2.0 certified aftermarket chargers out there too, Qualcomm did a lot of work on the front end as part of bringing it to market. (Just make sure any AC charger is UL listed or equivalent, if you care about safety.
Caveats on cables: The cable does make a difference at higher charge rates. Thinner gage wire will impose a greater voltage drop at higher current, this will reduce power and thus increase charge time.
Typical USB cables are AWG 26-28. You can buy 20, 22, and 24 AWG USB cables. Some cables advertise heavier (22-24) gage wire for the power leads with standard (26-28) gage wire for the data leads. The aftermarket QC 2.0 AC chargers I bought listed their included cables as 20 gage.
Get the heavier gage if you want full QC 2.0 charging.

I still have my galaxy s6 nexus charger that is a fast charging and it seems to work fine with turbo charging

Just to check did you use S6 original charger ? And does it charge same with the turbo power charger provided by moto?
