Hello,
this question is for Nexus 4
I lost my charger but I have my 2amp charger. Can I charge with 2amp charger on regular basis? What problems may occur in the long time? Please suggest. thanks all
It's fine, your device only draws the amount it needs from the charger.

I have a 800ma charger that seems to take forever to charge my phone. I also have a 1A charger that charges significantly quicker. I am trying to determine if the cheap 800ma charger I have is just a crappy charger or do 1A charger charge that much quicker?
OE charger is 1A, from what i've seen it charges the phone the fastest, i should check what my charger at work is b.c i find it charges way slower then the OE
1A is the most it will take or you can just plug it into your computer @ 500ma. So 800ma will work just fine
great to know thanks so much!
The phone detects if you are using a wall or usb charger, the second is considerably slower. Some usb chargers cheat to seem wall chargers so charges much faster.
My Samsung Droid Charge charger has an OUTPUT of the same voltage and 700 MILI amps.
My Blackberry Bold charger OUTPUT has the same voltage but is 1 AMP output... or 1,000 MILI amps.
If I use the Blackberry charger in my new Samsung Droid Charge will that mess anything up in the Samsung? could it shorten the life of the battery?
Thanks!
sure can, including wall chargers and car chargers
well if the amperage doesn't match exactly couldn't that mess up the Droid Charge?
it should be fine...but you might confuse your phone into thinking that it is a cutting edge smartphone circa 2006
If the power output of the charger you want to use is rated at less than what the OEM one is, you would only damage the charger itself if it isn't made properly.
The phone will pull a specific charge from the charger, say 500mA as an example. If the charger is rated at 400mA and doesn't have wiring to prevent an over-draw, you will damage the charger, especially if you use it for extended periods of time. If the charger does have circuitry to prevent over-drawing power, you'll just charge the phone slower. If you use a charger rated at 1000mA and the phone pulls down 500mA, using a higher rated charger doesn't make the phone charge faster as it will still just pull the 500mA. You'd just be less likely to damage the charger using one rated for more than what the device will accept.
Charge faster

I had purchased a usb cable a couple of years ago on kijiji for my BB bold back then because I didnt have a charger for it. Then I got the S3 and one time I randomly used the BB cable connected to the S3 charger via USB, I noticed the phone charged WAYY faster than the normal S3 cable does. Now I got an S4, and it still charges a lot faster than the normal cable for it. In fact I'm charging both my S3 and S4 at the same time right now, the S3 with normal cable charged from 4% to 15% in the exact same amount of time my S4 charged from 48% to 72% with BB cable. Does this mean I'm damaging my charger that's connected to the BB cable?

If by charger you mean that little box that plugs into the wall, that is actually a power supply. It just converts 120VAC 20A to 5VDC and whatever current it specifies. Also the stock s4 uses qualcomm quick charge, which means that if you use the stock power supply with the s4, it will charge at up to twice normal speed, provided you have a compatible cable (which it seems the BB cable is).

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.
On the Samsung Galaxy Note 2 (basically all Samsung Galaxy device), their two data pins on the official charger are shorted to be verified as a official charger and enable fast charge. If I connect it to a no-branded usb 12v charger, it takes a very very very long time to finish charging (like 5 or more hours bevause it only want to recieve 350mA rather than the higher rate on the official charger). I remember I dont have any problem charging my HTC Desire HD with the Samsung charger. But if I use HTC charger on Note 2 it also needs hours and hours to charge.
My question is what brand/model uses the 2 data pins to verify (or know how to charge when they are shorted) so that damage will not occur. Anyone knows the answer?
Several things going on here. There is a difference between USB and AC charging mode. I have had to short two wires in my car adapter to get my Nexus 7 to start charging with AC mode. Don't assume that every charger is capable of charging at the same rate. If you have a 350 mA charger, it won't charge your device as fast as a 2A charger.

I didnt mean that every charger can charge at the same rate. I wanna modify a 2A charger but I'm scared that if I unexpectedly connect it to an incompatible phone and something bad will happen. If a no-branded charger (data pins are not shorted) is connected even it's on the wall plug, the device will set it as USB charging and lower the receiving voltage so the device will charge very slow or the battery percentage will be dropping even when charging while using. My HTC charger can charge the phone that it belongs (Desire HD) in 2+ hours but the Note 2 needs 5 hours (this means that the HTC charger has no shorted data pins). And the Desire HD wont get an error when using a charger with shorted data pins (Samsung charger). What I want to know is what phone cannot be used with a charger with shorted data pins in case someone (or myself) use my modified charger to charge a incompatible phone and let damage occur.
As we know the original N5 charger is 5v 1.2A, so can I use Galaxy Nexus charger which is 5v 1.0A will it damage my phone or any other problem
sry my poor english
Yes should be fine

It is the phone that decides how much current to use, not the charger. A charger can limit the phone only if it is not able to supply enough current. If the phone is capable of charging at 1A, a 10A charger will only deliver 1A. The current ratings on chargers are for MAX current the charger is capable of.
