Is it just me

Charging wise this is the fastest charging smartphone I've ever owned. And I'm a phone whore. From hero, instinct 1/2, evo, evo3d, hd2, note, and a few others. Anyone else notice

It seems to charge pretty fast from the A/C charger but plugging it in to your Pc seems to take FOREVER.

Mine takes forever charging no matter what. Ive put it on the charger at 50% and it took 3hours ish to get back to 100%. Granted my phone could probably go two days with four hours of on screen time too.

Granted I can't speak for stock because I rooted asap. I mainly use AC 95% too. Not sure if how much root affects it, I'm on synergy (awesome btw).

mathematically yes. My old droid x charged at a max 750ish mA. The S3 charges at 1000mA

It is just you...
In my case at least.

Charging on AC is really fast for me too. Car charging and PC charging not so much.

GNEX was my fastest charging smartphone...but also had the worst battery life.

I am betting it's because most of us have 1amp or 2.1 amp chargers available in the car. I, personally, still use the motorola 950mAh car charger, which speeds thru the charging process too.
USB still pumps out 500 mAh at best, always gonna be slow.
None of this has to do with the phone, btw.

Slow charging for me. But its random. Sometimes its decently quick but other times it takes forever to charge. Fastest phone to charge for me was the OG droid.

I've noticed that when its plugged into the wall charger, its super fast, computer though is utterly slow.

Its really fast, about an hour and I'm at 100% from 0%.

There is a thing in the charging port that only the samsung charger activated that allows charing upwards of 1000 when using normal micro usb only does 300.
If you download imosyens leankernal he developed it into the kernal that you go to terminal editor and put "ffc"and charger will go as fast as thr samsung one.

Lol I'm the opposite. Coming from a Galaxy Nexus this phone charges much slower. Galaxy Nexus would be fully charged in maybe an hour and a half. With the GS3 it's closer to 3 hours for a full charge. Hear it's the low-power brick that comes with it though.

Yep. For example, the Motorola SPN5400A will charge the S3 in about 1\2 to 1\3 the time it would take if plugged into a USB port. I honestly believe it's because it has quality internal circuitry. Hell, at .95 mAh it charges quicker than most 2.1mAh chargers. Again, has nothing to do with the phones, it's the chargers that come with.

mine charges pretty quick as well. best phone ive had hands down.

3 hrs seems off. I think I could wire mine to my electric razor and charge it faster
From the I-killer

Just for info, my wireless energizer pad and Verizon wireless door charge faster than the factory charger. And my factory charger will charge between 1.5 and 2 hours from 3% or 4%.
If you are taking over 2 hours I would check the battery and make sure it isn't swollen or something wrong with it. As far as usb most ports are "as stated above" not going to supply juice fast enough to charge quickly.
And it's probably worth seeing if something is on thats sucking power, Bluetooth, gps, facebook, anything that sync's alot. And using almost as much power as the usb is putting out.

Maxell air voltage qi wireless

Ive seen threads for almost all the wireless chargers except this one, so ive decided to create one to unite all the information.
Ive just ordered it on amazon for 50€.
What is your experience with it guys? Cant wait to recieve it.

I have one here and it works fine, charges my phone with no problem and temperatures never go above 36c. The only two issues I have is firstly the Nexus 4 slides around on this thing like there is a layer of Teflon between the phone and charger. I heartily recommend LEAVING the protective film that the Maxell comes with ON the charger that stops the phone slipping.
Secondly forget about using daydream with the charger, in my experience daydream uses up too much power to be useful with wireless charging. The battery charges at snail pace and the phone heats up to over 45c with daydream enabled. I like the Maxell and I like wireless charging my first choice would be the Nexus Orb if it was available, but the Maxell does a good a job as any.

Thanks for the advice. Will keep maxell plastic on. Wish they could deliver it faster. Will take a month

Just got one of these from eBay for £42. Seems to charge fine with the N4 the S line TPC case on.
My only, albeit minor, issue with it is the bright blue LED which illuminates while charging. This is easily resolved by making sure the N4 covers it or stick a bit of dark tape on top.

I just picked a Maxell Air Voltage charger up from Ebay here in the UK, it is a very nice bit of kit I must say and works great, the only downside is that the charging range isnt too good, I was expecting at least 6mm so that I could charge it whilst it was in my flip case, it wont charge through the flip case and it wont charge through any case that is metal or has a foil liner this of course is fairly obvious.
i am sure some of the thinner plastic half cases and gel cases it will be fine, I think that the Nillkin Fashion Shape Flip Leather Case is also OK with it so I will pick one of those up with it.
I tested the effective range with UK 2 x 1p pieces stacked on top of each other which is 3.0 mm thick in total, so if your case it over 3mm thick then it wont work without taking the phone out of the case, something to think about if you are going to get this charger.
I wouldnt hang on to get the orb charger, thats a long way off IMHO, the Maxell air voltage is a great unit, is cheap and will work with other QI devices, well worth getting it.

Sounds good so far. I've ordered mine off Amazon after hesitating because of the price.. Taking ages to arrive during this holiday season. Looking forward to it.

Had mine for around 2 weeks now, works perfectly with my tpu case on.
Did originally have daydream turned on and it was a little slow but now its off it charges great.
Well worth the money. If they were a little cheaper i'd buy another!

hi,
does it use 110 or 220 voltage?

I also have the Maxell charger of Ebay and it charges through the Nillkin hard case with no issues at all which was a deal breaker for me if it couldn't.
I agree with the comment to leave Daydream off as it seems to charge the phone better..

Cheers mate, I was a bit worried about charging through my S-Line case. I've just ordered one from play. I have a desktop stand, but sometimes the connection doesn't fit in properly.

Got my nillkin case for my n4 which is superb and can confirm the Maxwell does charge through it as the other poster mentioned so it isn't a one off, if the case was a little thicker it won't do it though so be warned

Mine is getting stuck at 89%. Then it goes in to a state of limbo where it disconnects, uses up a bit of charge, reconnects, gets back to 89% disconnects, etc etc.
Anyone else? Defective unit?
Also, has anyone else suffered severe battery life deterioration after using this? It may well just be coincidence but about 3 days after first using it my battery life has fallen off a cliff. The Android Kernal OS is suddenly showing up at over 30% usage on the stock battery data page, whereas before it was under 10%.

Working fine with mine no problems. But I find when it charges to 100% it waits until it drops to 95% before recharging again. This is fine as I understand that qi charging doesn't allow for trickle charging, so it's either full power or no power. I wouldn't say it degrades the battery life but rather it screws up the battery stats. To fix this I just plug the usb charger once a week or so.
I think the capacity reading gets messed a bit as due to the on/off charging after reaching full charge, since unlike trickle charging where the battery's voltage is kept constant, the voltage is always raising or falling. Depending on when you take your phone away with you in relation to its current charge state you might get a slightly lower capacity for that particular charge.

What im going to do to solve this is buy a electricity temporizator and set it to 3 h so it stops once those hours are done. I always charge mobile at the same hour.

Trickle charging is horrible for lithium ion/poly batteries. Unplug from AC charger as soon as you can. LiOn batteries don't like to be at full peak 4.2v for long. It's actually better that many of these Qi chargers are only charging to 89 or 95% of capacity by the wireless charges. It's better for the long life of the battery. Charge them often too. Don't let it go down to 10% or 5%. Put them on the charger when your phone is down to 50% and take them off the charger when they get to 90%. It's easy to do with a wireless charger.

I'm actually aware that constant trickle charging at full charge isn't ideal for long term health of the battery. Which is why I mentioned I only plug the wired usb charger once a week. I only plug it in for about 30 mins so the voltage stabilises as to help the phone more accurately display its charge % state better. Obviously it's all subjective as I've yet to actually perform any tests to see if it's ture or not.
On the subject of long term battery health, trickle charging on wired may not be ideal, but nor is wireless charging due to heat it produces. During wireless charging, according to my battery stats widget the phone reaches 39°C, while wired usb it never goes above 22°C (room temp. basically). The good thing about wireless charging is the heat drops back down when the battery is full and the qi charger is no longer sending any current. But when the charge drops back down to 95 % it restarts charging again, and the heat returns.
So, which is more harmful to the battery, heat or constant trickle charging? In either cases it's still a good practice to remove the phone from the charger (both wired or wireless) once it's reached full charge.

Wireless charging.. Good or bad?

So I figured a wireless charger will prevent my otterbox from stretching out and all. What ive found to be a pain in the ass compared to all videos ive seen. Every one people just throw the phone on top. Comes on charging. My phone complains for me to center the circle on the screen with the dot in the center of my QI charger.
Anybody else notice this? Or is the droid maxx just a pain in the ass to wireless charge?

I think it's a good idea. This is the reason I bought the Palm Pre

Hi, I think there are a couple of technical specs being quoted.
. . . my s4 stock charger charges at 2 amps a second . . .
Click to expand...
Click to collapse
I think you meant the charger rating is 2 amps. Battery has a rating of amp/hr, but not chargers. They are only rated at amps. E.g., if a battery is rated at 60 amp/hr, and it is flat, to fully-charge using a 2 amp charger it will take about 30 hrs (30 * 2 = 60). That's only theoretical because other factors take into play: the condition of the electrolyte, the physical condition of the battery, the performance of the charger, ambient temperature and humidity, etc.
. . . the wireless charger only charges at around .5 amps so instead of taking around 2 hours to charge it would take around 5 hours. . .
Click to expand...
Click to collapse
If charging at 2 amps take 2 hours, then charging at 0.5 amps will take 8 hrs (2.0 / 0.5 * 2 = 8)
In the above examples, I am assuming that the battery and charger Voltage rating is the same.
Just clarifying.

I want a spot in my car where you set your phone and it wirelessly charges while playing your music via bluetooth and doing calls/texts via bluetooth and voice. Set your phone there when you get in the car and it is fully powered, charging, and ties into everything. It needs some mechanism to keep the phone there (some sort of clamp?) and be positioned well for GPS usage.
Wireless charging will be awesome once there is a standard and it starts getting built into things like that.

Think of it as a transformer with the primary and secondary coils not firmly attached to each other. It's no more dangerous than any AC adapter. Of course, if they decided to make these chargers to work at a distance, there might be some risk. (shades of Tesla!)

I totally agree, there should be thorough study on the electromagnetic waves not affecting the memory cards and the volatile storage inside the phone... might result in data loss?

ZeroLemon 7500 deplete during charge ?

I am currently using now the ZeroLemon 7500mah. I have the Samsung USB component plugged into the wall, then a USB extension cord, then the actual Samsung cord. When I have the phone on and plugged in, in the stock battery the phone still charges when I use the phone while plugged in. I noticed the ZeroLemon 7500mah battery actually depleting while plugged in while being used.
Does this happen to anyone else ? Just making sure it is not a battery issue.
It charges when I leave it alone, but when I am playing with it plugged in it is using power.

Never happened on mine.
Just charging slower when being used.

Likewise. Never depletes just slower to charge when being used. And I'm talking watching films which have a lot of drain. Sounds like either a battery or charger issue. If you have another charger give it a try and if the issue continues I'd get them to send you a new battery.

How to stop battery from charging

Hey guys, does anyone know a tweak where my phone will stop charging at like 99% so that when I charge overnight, it doesn't over charge? Or is this already a feature in many custom kernels such as elementalx

It's a feature of the phone itself. Don't worry about it
Sent from my Nexus 5

With all my phones, I've always left them charging overnight. As jd1639 says - they are designed to ensure they are not overcharged. This is both to protect the phone and also not to waste electricity.
I use an old Motorola charger by my bedside which is rated at 500 mah. As it's going to be plugged in for 7 or 8 hours, it might as well charge slowly! It's better for the battery that way - maybe see if you can pick up a lower-rated charger if you want to be extra careful.

I've not heard that anyway, but is 500 mah "too slowly"? That's the output you'll get from a USB drive.

Ah right... Just looked it up. If it's an ac wall charger. It's ok. If it's a usb port they generally give out less voltage (around 4.2-4.5) so your battery won't last as long between charges

If the battery is fully charged it shouldn' matter what voltage was used to get there. A full charge is a full charge.

This isn't true. A charger only works by applying a voltage to the cable which causes electrons to flow into the battery. The N5 battery is at full charge at 4.2V. If you're charging it with a supply that is running at less than 4.2V it will only charge up to the voltage applied.
Edit: I guess to clarify I should say that you're right that a "full charge is a full charge" but you will never get to a full charge if you are applying too low a voltage. And keep in mind that if your USB port is only providing 4.2A there is a voltage drop across the wire so you would end up with a lower voltage at the battery.
