I doubt if anyone is as lazy as me but when I first got my note 2 the other day I didnt bother unpacking everything and just charged my phone on my old note 1 charger. I was very disapointed on how long it was taking to charge so I checked the specs written on the side of chargers and noticed the old charger has a 1amp output and the new charger has a 2amp output. Just thought id share this as I know alot of you are previous note 1 owners .

If it was legit .7 amp charger, then it'd only take 3.1 mA/.7 = 4.4 hours to fully charge.
So something is wrong with your charger or widget.
I highly recommend a widget like battery monitor widget so you can observer how fast your phone is charging with whatever charger/cable combo you are using.
Some of my old note 1 chargers are happy, like my griffin car charger. Others, like my t-mobile 1A charger, definitely aren't.
YMMV.

In the meantime I got inspired by some threads in which people claimed that 2A (amp) charger will make it faster to charge up my note then original 1A charger. I bought original Samsung 2A charger for Samsung galaxy tab and tried that out and I must say that during the first week or two the charging time decreased from around 2.5 - 3 hours into something around 1h 40-50 min.
Later on everything returned to standard 3 hours though, charging with 2A charger is almost identical to 1A charger so from my experience there is no added value with this approach (unless ICS will make a change, or some custom rom).
For anyone interested I enclosed picture where in the top row you may see charging with 1A charger after 1h50min, 2h40min (both just random pics), then when this app (https://market.android.com/details?id=net.whph.android.battery) said it is 100% and the last picture is when galaxy note (Android) system said it is 100% (green battery icon). In the bottom row there is the same scenario with 2A charger. I am on the stock rom 2.6.35.7-N7000XXKKA.
Im not sure but I think you need a kernel that allows more than 1A charging for the 2A charger to work.

I guess so, what makes me slightly uncertain is that initially, charging time was around 2 hours ...
This is an interesting thread. I'd like to get more information about 2A chargers and whether they really make a difference.
Also I heard that when plugged to a TV (using the MHL cable) the phone may actually consume the battery more, even when plugged to the charger simultaneously. therefore if 2A chargers charge faster, it may also solve this problem.

I actually have both, micro USB to USB and micro USB to MHL cables. Wasn't able to test them for a longer time as they sometimes work and sometimes don't, especially mhl cable shows videos for like 30 seconds and then there is a lost signal message on my TV, then it wakes up, then it is gone again ... I could fiddle wit it, but will rather wait for ICS upgrade and then will return to it again.

Iphone charger
I am using the iPhone charger. It is a 2A and so far I see an improvement in the battery life. With the original charger (and BB one) the battery reading was 2100mAh . Now is 2600mAh. I don't know why or how.
Also I see a sightly improvement in how the battery lasts for normal use. I get around 18hours

What we need is someone with 2 notes with dead batteries and plug the original charger 1a on one and a 2a charger on the other and see which one gets fully charged first! Maybe its me but I can definitely see a difference between the original and the one I'm using (playbook charger 1.8a)

I did it, and while not with 2 notes side by side, you can have a look at the pictures at the 1st post, the time and charging rate shows its pretty same on the stock rom whether you use 1A or 2A charger. (Although it was very different first one or two weeks, after that battery get used to 2A charger and charging is as slow as with 1A ...)

SGN stock batt with ipad charger?
Hi, I see some of you are using 2A/ipad charger to charge you SGN. My question is, will there be any side effects on that could harm the stock batt in short or long run?
FYI, atm, I have an ipad charger for home and car and i intend to just use the same charger to charge all devices including my SGN. Im not looking for a fast charging option, but just a hassle free and conveniences.
I appreciate if you could give suggestion on a dual port charger (for home and car) where I can charge my devices simultaneously at one time.
No harm as long as the volatage output from your charger is 5v. This is what pushes the current to ur device. Higher it goes more it pushes.
However the current that the charger provides decides how fast it can charge. This will also depend on the device. If the device is manufactured to charge at 1 amp and u use a 2 amp charger then it will only use 1amp. If however u use a 750mah charger it can only use 750mah and charge slowly.
@Taptalk-GalaxyNote
My wifes Galaxy S3 came with a 1amp charger. My note 2 came with a 2amp. Would it be better to charge the note 2 with the 1amp charger vs the 2amp? I remember reading a post that said the 1amp charger would take longer but the battery would hold that charge longer/better than what the 2amp would provide. The 2amp would charge it faster but the charge wouldn't be as good/longer lasting.
What do you guys think?
Thanks
Either one will work. I would use the 2 amp one. Just because the charger outputs 2amps it doesn't mean the phone will draw all 2amps.
the 2 amp charger won't get drawn for all 2 amps, but it will get drawn more than 1 amp. charging slower (with the 1 amp) won't mean it will keep the charge any better
Sent from my SPH-L900 using xda app-developers app
if you need speed use the 2amp. if you don't need speed you can extend the life of your battery by using the 1amp. (slower charge is healthier for the battery in the long run though not likely measurable by the likes of us)

There is a reason Samsung included the 2amp charger. The Note 2 has a huge battery. The 2 amp charger will charge your note 2 faster. The device draws the amount of amps it needs. The charge is held the same way, doesn't matter the amps. Im sure Samsung wouldn't include a charger that would damage/negatively effect the battery.

I used Charger Timer, https://play.google.com/store/apps/details?id=com.vexedbadger.chargertimer , to test the rate of the 2.0a charger the note came with compared to a 1.0a samsung charger from my wifes note 1.
2.0a
Averaged a 1% charge every 73.85 seconds @ 1511ma
It would take 2 hours and 4 minutes to go from dead to fully charged.
1.0a
Averaged a 1% charge every 110.62 seconds @ 1008ma
It would take 3 hours and 4 minutes to go from dead to fully charged.
I expected the 2.0a charger to be twice as fast, but that wasn't the case. Either way I glad this phone has 2.0a charging and will buy more 2.0a chargers. The extra charging speed is a nice feature I don't think any other phone has.
If anyone else wants to run any tests to compare I would appreciate it.

Yes.....I use a 2A charger from my GTAB 10.1. Its charges faster too.
lots of smart phones, like n7000, takes 1A(1000mA) from charger whether 1000mA or 2000mA charger.
So you don't really fasten your charging untill use custom kernel that enables that upper current(like 1250mA.. etc. But that not recommended.
But yes,u can use note 2charger for note 1.

Wrooong. 1A charger and 2A charger effects are same on n7000battery. Phone takes only 1A max as needed from both(in untouched kernel about current).
Charging cable's isolation,quality and length effects the current, and may slowingdown charging procedure.

So maybe with external charger we will avoid 3hours of charging?
Do you recomend a external charger like this?

Nope ! Max charge current is fixed by the Galaxy Note itself, one IC (SMB328) is programmed via I²C bus to do so.
So only a piece of softawre can speed up charging but don't forget that slow charge reduce heat increasing battery life span by the same way.
not even with external charger??

Chargers range from 1A-2A output. The cable will also affect the charge speed. I tried replacing the cable on my Samsung charger with a cheapo $1 one, and it wouldn't charge for crap. Swapped it out for a higher quality one, and it worked great.
I might keep my note 3 charger for this. Usually charge quickly.
The G3 comes with a 1.5a charger and takes about an hour and a hlaf from 18% to 100%. Would using a 2a charger cause any damage to the battery or would ut be safe to use?

My AT&T G3 came with a 1.8A charger. It's a lot bigger than I expected. Charges my phone in about 2.5 hours.

Tmo variant ships with a 1.8A as well. Not sure what you've got that came with a 1.5A. Charges in about an hour and a half with my longer cable I've got at home and 2A samsung charger I have at home. I don't use the LG one it came with because it's too tall. It's about double the depth of the charger that I currently use and I've got it crammed behind a file cabinet. Also the cable coming off the end of the charger instead of the side is a poor design considering that the charger is already so deep to start with. The charger it came with definitely wouldn't fit back there.

i read on a review that the charge times may vary from 2 hours to 3 hours
Hi everybody! With the originale charger and cable my G3 has a very, very long charge time. About 4 hours or even more... One morning I found it at 92% after all night (from 00.30 am to 7.00 am).
What do you think it depends on? May I have some hw issues? Now I use another charger (not LG's, about 2a) and it takes about 3 hours...
I'm going crazy about it! Thanks...
