I've noticed that charging with 500mah charger, charges the battery MUCH slower than a 1000mah (1amp) charger, which charges really fast. I'll need to time it, but I'm thinking the 1000mah charger charges the stock battery in less than 2 hours, where as the 500mah charger takes many hours, I usually let it charge overnight.
My question is, is there any performance gain to slow charging vs fast charging? ie: slow charging giving a deeper charge, vs fast charging?
any opinions?
i use a 2amp charger i had already that fully charges the O3D in around half an hour/45 mins. get the same runtime whether i use that or the stock charger.

Any chance of a link to this charger, I'd really like that sort of charging speed.

My guess would be anything that would charge an iPad... those require like 2.1amp, so that would be a 2amp usb charger.... I've seen 2.1amp home chargers, car chargers, etc... all because of the ipad I'm guessing.
Its not that simple. Any device that uses USB for charging can only pull 500ma, that's a universal agreement. To get around this each manufacturer uses a method of "informing" their device that it is connected to a charger that can supply more current (HTC shorts the data leads in the supplied charger I don't know what LG does). I have a 1amp car charger but it still only gives 500ma but the genuine LG charger gives an amp because the phone "knows" it can supply more.
I'm going to stick a test meter into my LG chargers over the holidays to see how the data leads are connected.

The charger i have is a noname brand. I bought it from walmart for 6 quid. It also came with a 2amp car charger and a micro usb cable.
Micro usb cables are not standardised like that. Ive never heard of such a thing at all. As far as i know most phones will "fast charge" if they dont detect a data connection and dump as much current as they can into the battery so you can pretty much present them with whatever current you like and the charge time will just get faster. There is probably a hardware limit to that somewhere in the charge circuit but i dont know what the limit is. 2amps is the highest power usb charger ive seen but its not exactly aomething i regularly keep an eye out for.

Slow charging is always better as this will allow the optimal number of battery cycles before the battery's capacity will start to degrade.
So if you only ever slow charge then your battery will have a longer life cycle.
Hello, I have a question regarding charging. In fact, when I use the OEM charger which provides 830mA of current to charge my Atrix 4G, it charges fast (~+50%/h). However, when I charge it with the charger of my Note 2 which supplies 2A of current, it charges very slow (~+12%/h). So, I find this very weird since theoretically it should charge even faster than with the OEM charger that came with it since it supplies a greater current. However, when I charge the Note 2 with the Note 2 charger, it charges with a reasonable speed (~+50%/h). Any explanation?:banghead:

well the note 2 has a 3,100 mAh Battery and needs a specific charger for it becuase its a big battery, on the Artix 4g its a 1,930 mAh Battery, if you look on both of your chargers (the wall mount)it can show how much Volts,Hz,mAH it will charge.
The charging current of a battery is limited by its physical capabilities. You cannot charge a battery designed to be charged at ~800mA with 2A of current - your battery would die very quickly and possibly even catch fire. Each phone has a circuit that limits the charging current to a value that is known to be safe for batteries used with that phone. This means that plugging a bigger charger to a small phone won't make it use the full capabilities of it.
Besides - in case of Li-Ion batteries, the faster you charge the faster your battery will degrade in time. This is the reason why I charge my battery using a USB connection to my PC, where the charging current is limited to 500mA (USB 2.0 limit).
I have ordered a Moto G from England (GSM global version I presume), and while I am waiting for it to arrive, I would like your advice on what kind of wall charger to buy that would be optimal for the phone charge recommendations since my knowledge on the issue is very minimal.
I read somewhere that Motorola recommends between 0.5 - 1.5A , but that doesn't really tell me anything.
I have an old Samsing galaxy SII. Can I use the charger of the Galaxy for the Moto G? The output is 0.7A
As you said, any charger where the output is not too high (I recommend below 2a or below 2,5 to not stress the battery.
Conclusion: your samsung charger should work perfectly!
Edit: if you experience bad/not so good battery life (I did after update to kitkat), let your phone drain completely (shuts down) and recharge it to 100% and leave plugged in like 30-1h after it reached 100%.
But don't do this too often as it will harm your battery over time.

Thanks. With 0.7 output would the charge be slow or fast?

Using a charger over 2A doesn't stress the battery because the Moto G limits the current to 1.5A.
It says so right here : https://motorola-global-portal.cus...prod_answer_detail/a_id/97318/p/30,6720,9050
”Any Motorola charger with the correct micro-USB tip will charge your Moto*G. You will see the best results when the output of the charger is between 500 mA and 1.5 A. The higher the output, the faster your Moto G*will charge.
If your charger output is higher, the MOTO G will automatically restrict the charging rate. If your charger is lower, it will simply take longer to reach a full charge.”
I use my nexus 7 2A charger daily and it charges noticeably faster than my 1A HTC charger and is as Motorola stated, perfectly safe.
A 0.7A charger would charge pretty slow!

Im using a HTC charger i already had which is rated at 1a ,seems to be working fine.
my 0.5A from 20% to 100% ~3 hours. When charging from less than 20%, I often put my phone to aeroplane mode and get ~3 hours of charging too

Many thanks. Could you recommend me on a good and not expensive charger that would do the job and charge it fast?
Since I dont live in the US, amazon is kind of useless to me since there are very few items they ship outside the US, so eBay would be a better option. I just dont want to buy something crappy

I use a Blackberry branded 0.75mah micro usb charger which works well as does my Samsung Galaxy Tab2 which is 2amp charges nicely too.
I found an older HTC usb 0.7 charger did not work at all well for some reason.
charger doesn't push power, phone draws power, as long as you have the right voltage you are good

Indeed but I've found some chargers vary for example my Samsung 2amp Galaxy Tab2 charger will not charge my Moto Defy+ phone, it sits there forever doing very little but the Moto G is fine with it. Probably due to the Defy+ only drawing 500mah and the Galaxy charger sees this as undercurrent and doesn't output whereas the MotoG can demand up to 1500mAh current which the Galaxy charger sees as acceptable and supplies the current.
I'd avoid any of the super cheap nasty Chinese crap chargers that seem very poorly built, unstable and potentially a death trap.

Sorry I meant to quote the advice above that said don't get something with too large a current.
Absolutely avoid cheap chargers, burnt home totally not worth the savings. The hp chargers left from the time they used to make tablets are pretty good actually, tested with an oscilloscope
I dont want a crappy cheap Chinese charger. Thats why I am asking for a recommendation. I have a nexus 7 2013 and the output is 2A. I assume I can use it also to charge the Moto G?

I'm curious, is your 2A charger for a 2012 Nexus 7? Because I also plan to use my 2012 Nexus 7 charger on my Moto G, which is coming next week. How quickly does it charge the Moto G?

Yeah my nexus 7 is a 2012 model also, works just fine and charges really fast. I'll stopwatch my next recharge and report.
Edit: It charges from 10% to 100% in 2 hours with my nexus 7 2012 2A charger while incidentally using it.
Next charge I'll try my HTC 1A charger to monitor the difference

Great, thanks for finding out!
I have a charger from Htc Explorer with this specification Input: 100-240v~200mA 50/60hz / Output: 5V-1A , and don't seems to work very well, is normal???
Thanks in advance
Are there any people here using a different charger in order to charge the Z3 a little quicker? As it is, it takes forever to fully charge the battery, especially during the last 5%. I want to try the turbo charger from Motorola but I'm concerned of ruining my battery.

The stock charger is pretty fast for me already. What is ur charger's amperage?
Sent from my D6653 using XDA Free mobile app
I use the 2.0A charger that came with my Tab S. It charges reasonably fast. However, if you use the magnetic charging cable, it'll charge the phone faster.
I bought the motorola quick charger. I definitely don't plan on using it all the time. It'll be a travel charger where I might need to add some charge in a pinch.
There's a thread documentind the rate at which different charging methods charge at. I put my Turbo Charger results at the bottom.

I have imported my Huawei and I absolutely love the phone. Since it is an import it came with a UK Type fast charger. I simply used a wall adapter and powered it over the US current. Well, that fast charger isn't working what so ever - after 2 hours I only go to about 35 percent from 0. I have used my Note 7 charger to charge it, and there the charging times are much faster. Any ideas on what, if anything, I am doing wrong and maybe where I can buy a working Huawei charger. I can't return the charger since I bought the phone over Amazon and it strictly came with no warranty. It is not the end of the world if I can't use the included charger I just want to see how fast this phone truly charges.
Either this post is a joke or someone sold you a non supercharge Huawei charger. Also are you using both the charger and charging cable that came with the phone in the box. It's white with purple in the USB A area
Here from 10 to 80% in 45 minutes
Same here. I find the first 80% to be lightning quick and then it slows to a "normal" charging speed for the last 20%.
Must be something wrong with your charger or cable.

Using the european adapter, not the UK one, but charging is lightning fast for me as well.
hi
the orginal adapter and cable
i charge from 0% to 90% in about 55 minutes, the last 10 % are slower maybe 30 minutes to full
greetz benji
Mine took almost 2 hours from 48% to 100%. I'm using Original Huawei charger.......
Install ampere and see what the milliamp charge rate shows as. When the battery is almost dead it should charge at just under 5 amps and will slowly decrease as the battery level increases.
Mine typically goes from 0 to 65% in half an hour, then 90% around half an hour on top of this. The final 10% takes almost another hour.

Well there is obviously something wrong with your charger, cable or phone. I would guess the first two.
Mine turbocharges in a few minutes. I've been using fir about a year now.
Could be that an "European" charger intended for 220 volts does not provide rapid charge when plugged into a 110 volts wall plug. I have for example an electric toothbrush I bought here in Europe and it refuses to charge on a 110 volt system when using an adapter. Maybe see if you can buy an OEM charger intended for the US?
There are 2 different chargers that are official, there's the supercharge one that comes bundled with the phone which I guess everyone is using and is getting great charging speeds... (Gotta use both the charger and the cable)
And then there's the fast charger which is pretty slow compared to the bundled charger.
The next time you wanna travel abroad make sure you buy a supercharger for that regions type of socket.

If you buy a replacement make sure it actually says SuperCharge on it.
