Can I use chargers from my previous phones?

I cannot use my droid 3 charger because im in Europe (different socket).
The droid 3 charger says 5.1V / 850 mA
Can I use my samsung charger 5.0V / 700 mA?
Thanks

You can use any microusb charger, if the current is lower the charging process is accordingly lower.
Currently I'm using a Palm Pre charger which can supply roughly 1A and charges the extended battery in about 2h

I know that the mA can be different, but I always thought that voltage needed to be the same? It doesn't matter that it's 5.0 rather than 5.1?

It's usb, the voltage is 5V in any device .1 V means basically nothing

Actually that .1 is the basis of all "rapid" chargers. It definitely makes a big difference. My I pad won't charge at all on 5, but it will accept any 5.1, including my d3 charger.

0.1 is pretty negligible, that shouldn't matter to charging. The car charger I use is Motorola branded and specifies an output range of 4.75 to 5.25 volts due to the noisier electrical environment in a car. I've never had any issues with it.

Chargers that don't charge, are usually non standard ones (read the data + and data - pins aren't connected toghether.
In that condition some device charges, some slowly charges, some don't charges at all.
Depending in how strictly they follow the standard.

I'm curious to know why manufactures always tell you in the manual NOT to charge the device using another charger than the supplied one, but what's the point of having a microsub standard then? i'm hoping they mean cheap chargers, but i think our phones would be fine using chargers from big companies like htc, nokia, blackberry, i think my galaxy s ii would be fine using my motorola charger

ok got access to pc heres the pic
and why wasnt i able to upload pics from mobile phone??said some system error 2...thx

Most of the time, I used the supplied charger (this is when I charge while sleeping, for example.) However, I have charged with other microUSB cables (i.e., my Kindle cable, a previously-owned Verizon car charger, and just a microUSB cable I found sitting in my collection of cables) and they have always charged fine for me.

I can't use any of my HTC chargers (Desire Z, Legend) or my car chargers. I also cannot use a USB cable extension, and the phone requires a USB driver to charge.

5 vs 5.1 is almost nothing the important thing is how much current mA you can supply 700 800 1000 2000
The ipad doesnt charge well with 1000mA or below but is happy with 2000mA
And an ipad charger charges my droid in less than an hour

Yes.. but is there a limit to mA or could I connect a 4000mA charger (theoretically) and charge it in 20min?

Assuming a constant voltage (our case) the charging current depends on the load .
So, if the charge can supply a limited amount of current (eg. 500mA) the load can't draw more than that, but if the current available is more than the one required by the load (eg. 5000 A), doesen't matter, the load itself cant draw more than the nominal one.
Maybe that limit is not 1A but 1.1 or so, but definitely not more than that.

Ye so the phone is pulling energy rather than the charger pushing it..?
If the limit would be 1.1 how would you explain the ipad charger charging in less than an hour?

Look the matter this way:
The charger pushes the current with a force (the voltage), and the phone allows the current to flow.
Look the matter as hydraulics: if you have a tap with a 5mm hole, and the water is at a definite pressure, there is no variation in the water flow changing the size of the pipe (assuming the pipe is decently sized).
What matters is the input pressure and the tap's hole.

I've never opened the american D3 charger so I've no clue on it's real performances.
BTW, in the real world, the Milesone 1 charger charges (roughly) at 900mA, the X2 one at 850mA, the Desire Z one at 1A.
Often the real performances of the chargers has little to do with the one written on the sticker...

I can charge my D3 with my LG micro usb cable, but I can't connect to my PC or macbook with it :-/

I use HTC 5V/1A,it is perfect

That's not true. Well, it might be, but you should to check _all_ different chargers to tell ot for sure. If the delivered electric potency (i.e. the voltage value) is the same, you can use the same charger even if the electric current output is higher (of course in reasonable limits, if you charge with a 3A charger if the device is certified for 1.5A, it's very likely to damage the board). I used to use a 1A HTC charger with my Galaxy R the original charger of which delivers 0.8A and it caused no problems.

Using higer amp charger

This might be the stupidest question i have ever asked in XDA forum but..... I really want to know the answer to make sure it won't do anything bad to my Z1.
I used galaxy note 2 charging adapter which is a bit stronger than the original z1 charger (1500mA Vs 2000mA) and found out that charging time difference is quite noticeable. i guess 500mA difference is huge.
Since I read few news that people were experiencing fire or explosion while they were charging (or something, which i don't know if it's 100percent true) i want to know if putting too much power is bad for the Z1.

the charge for z1 is 2A. You can plugin 3A, but it wont take that extra, can only accept max 2A.
Generally speaking having extra 1A wwill heat up device but wont cause fire, unless you put in 1000A then it will explode

Use whichever charger you have. Using a 2A charger will of course decrease charge time. Using a 3A charger will do nothing for you, because phone only accepts 2A if I remember correctly.

Using a 1000A or 3A charger will not make a difference. Phone will not heat up more than using a 2A charger. The phone will draw those 2A and nothing more. Unless there's a custom kernel parameter we can change to increase charging current.

That is correct. Stock supplied charger is 1.5A, at least in the scandinavian countries.

I charge my Z1 with N7 charger (2.0) and everything is O.K.
Just like guys said - Z1 can use up to 2.0 and it's perfectly safe to use it but make sure charger is good, if you use junk for 1$ you could damage your device.
If we gave 1000$ for device we can pay 10$ more for good charger.
Sent from my Z1

I only ever use the 1.5A factory charger if I'm leaving it overnight. Its too slow otherwise so I also use a 2A charger from my Asus transformer

Hey you who pretend to know it all, let me clarify
You are saying the official charge is 1.5, but also say it take 2a as well, let me ask you, why do you think the phone can only overcharge up to 2 a and not to 3a as you were denying me?
My charger say it is 2a, it is official, dont being rude and frankly deny other opinion, at least try "from my poimt of view"
Sent from my C6903 using xda app-developers app

U might have a real special packaging as it usually comes with only 1.5mA
Also snapdragon 800 supports quickcharge 3.0 which allows chargers up to 4.0mA
These chargers will release in 2014

Mi3/Mi4 supports Quick Charge 2.0?!

Alright, can anyone confirm this for me? Wait, lemme start at the beginning...
So I was reading this Android Police article, hoping to get some quoting material for those times when a member thinks USB Fast Charge is the same as Qualcomm Quick Charge 2.0...
http://www.androidpolice.com/2015/06/12/quick-rapid-turbo-and-fast-charging-explained-what-you-need-to-know-about-charging-your-smartphone/
Y'know, all those times people ask a kernel dev "Why isn't Fast Charge speeding up my charging?" so I could swoop in and crush their dreams with "Fast charge means only more current draw when USB charging via PC. You're thinking Qualcomm Quick Charge 2.0, which needs hardware support, so ain't gonna happen."
But turns out, the Mi3/Mi4 DOES have the supported hardware (for Quick Charge 2.0 mind you, not v1.0 like in the Nexus 5)
https://www.qualcomm.com/documents/quick-charge-device-list
(Official document from Qualcomm listing the Xiaomi devices amongst the handful of QC 2.0 devices)
So can someone tell me if this needs kernel support? Or can I just buy a Quick Charger off Amazon and enjoy the benefits?
Or if this is at all LEGIT?

In fact I own an Mi4 which comes with a 2A charger that is normally supporting quick charge 2.0.
With MIUI it's charging 1.8A (of course 1.8A is around 2A minus phone consumption)
On all custom rom it's just charging max 1.3A with about same consumption, or even less.
So Mi4 support quick charge 2.0 with MIUI but not with any custom rom or kernel.

Anything regarding Mi3 ??

In the attachment 1 that is the stock charger of mi3 , in the attachment 2 that is the current of quick charge without the build.prop line. And in the last attachment that is that current with the buil.prop line.
In conclusion, without the build.prop line the lcd becomes super sensitive but higher current, with the build.prop line the lcd is fine but lower current than before

I don't think a 2A charger is an actual Quick Charger. (Obv it charges quicker compared to 1A ones )
Apparently for Quick Charge 2.0 technology, your Wattage/Power input should be around 18W (wattage is found by multiplying the voltage written on charger, usually 5V with current you're getting in ampere). Quick Charge 1.0 supported upto 10W which we're gettng with the 2A chargers, but I think we need an actual Qualcomm certified Quick Charger (which allow currents of upto 3A apparently) to see QC 2.0 at work.

Yes, this guy is right. 2A charger with 5V output is not a quick charger this guy talking about (Qualcomm Quick Charger 2.0). 12V charger output is.

Mi4 charger comes with 3 voltages 5V-2A, 9V-1.2A, 12V-1A...but maximum we get is 12*1=12W

Charging on xc kernel (cm ROM)

MI3 is not support any quickcharge. Even you use 2.0A charger, will give you same about 1.2A

What i know is i had Mi3 in past now i have Mi4 and mi4 comes with a Qualcomm Quick charger 12V-1A. It charges way too fast than Mi3 charger.
I use Mi3 Charger 5V-2A on Mi4 it took 2-3 Hours to get fully charged whereas Mi4 Charger takes 1-2 Hours to get fully charged.
It heats up a lot Charger + Mi4 Both

MI3W support QC 2.0, but needed QC 2.0 charger, for example Xiaomi Quick Charger 2.0 aka MDY-3-EB I`m found it here

Are you sure a 2AMP charger makes a difference compared to the stock charger that ships with the phone? Could you download an app that measures the charging rate & post a screenshot of the charging rates?
I've tried charging with both a 2AMP charger and the stock & the results are the same, I see no difference in charging speed & no difference is shown on the "Ampere" app, both charges at around a max of 980ma with screen on (I assume it goes up to 1A, when screen is off).
