Living in Sweden, I cant use the original charger (without an adapter), so I'm using the iphone charger to charge my Nexus S. The iphone charger is 5v 1A, vs 5v 750mA on the original charger. It works, but it takes forever and forever. around 14 hours from almost drained to +90%. If anything, shouldn't it go faster?
Something broken, or am I missing something?
Swede here...Buy a European micro USB adapter?
Long charge times have plagued the Galaxy S line of phones since the origina i9000; seems to have improved on the NS for me, but it doesn't charge nearly as fast as an iPhone (but iPhone has smaller battery).
Yes, I'd expect a 1 amp charger to go at least as fast.
I'm curious if your phone charges faster on the USB port of your computer than you're getting with that charger.
Are you sure there's nothing wrong with the charger or cord you're using?
As soon as I saw .75a on the provided samsung charger I chucked it back into the box and have been using the 1a charger from my HTC aria instead.....I still get pretty slow charge times compared to my N1 but nowhere near as slow as you are getting!! (14 hours) I too would be interested to know how well/poorly your NS charges through a pc usb or another charger, it sounds like you may even have a problem with your device :s
That samsung charger is just a POS all around IMHO tho....its ugly as sin (freaking huge) and only .75a?? cmaaaaannnnnnnnnnn, samsung!!!
I'm using the little iPhone USB charger as well and my phone still takes over 3 hours to charge. Charging time is horrendous.
My charging problems occur perhaps every tenth time I try to charge it... So something with the negotiation seems thinkable...
Couldn't this hurt the battery/internals?

Hello guys,
I'd like to know if anyone here has experience of using a different brand charger to charge Foccus.
I have a Nokia E7 which comes with 1200ma microUSB charger. The one which comes with Focus is 700ma.
Since the battery of Focus is 1500ma rating, I guess there shouldn't be any issues?
Also, charging Focus via it's own charger takes too long to charge. So, using a 1200ma charger will charge it faster as well. Also, it's be far more easy to only plug one charger on power outlet.
Just want to be sure if anyone else has already tried non-Samsung charger with Focus, or any other recommendations / suggestions, before I plug my Focus with Nokia charger.
Thanks,
// chall3ng3r //
I've used a bunch of different methods to charge my Focus.
The supplied wall charger, a couple different car chargers, a motorola, LG, and Uniden wall charger, several USB ports on various computers...
So far, no magic smoke has escaped...
Hi,
Thanks for your reply and giving me some idea to try our the Nokia charger with my Focus.
As soon as I read your reply, I put my Focus on charge, and it's more than 20 mins without any smoke
I guess it'll be just fine
Thanks again.
// chall3ng3r //
I've also used and successfully swapped chargers for:
Omnia 2
Omnia 7
LG E900
Focus
Any charger/phone combo worked, with no issue.
Hello guys,
Are you still charging with other chargers? , have you gotten any issues yet?,
Please comment cuz I really bored to wait the slow and annoying charging of my standart package.

I also bought from ebay one additional battery and a battery charger (charges the battery directly). Works perfectly. (If interested, search "BATTERY USB CHARGER FOR SAMSUNG i9000").
With 2 batteries you don't need to wait for a charge/leave the phone to charge. I just leave the other battery to charge and swap it when the one in the phone is low. Besides, you have a backup this way too.
I'm charging with microUSB Nokia charger, Nexus One charger, and even iPhone charger with microUSB cable. There is no issue.
I'm using the charger from a Galaxy Ace and no issues.
I have used LG optimus charger and iPad charger (Which comes with 2100 ma output) no issues. But none of these changed or reduced the charging duration (including iPad's!!!)... It is taking 2.5 to 3 hours to completely charge... USB ports output is generally 300ma-500ma, so definitely not recommended!!
I have numerous chargers at home all of which have charged my evo, gs2, Nexus 7, etc.
Can these be used interchangeable in the Note 2 without harming the charging process?
Thanks
As long as the Voltage is the same (5V) there is no Problem. But you should have a charger at 2 Amper for optimal charging speed.
I just tried charging mine with the normal microUSB charger I use for every other phone I have had and it took 7.5 hours to charge from 5%-62%. I used the stock charger that was in the box and it charged it in 3.5-4 hours no problem. Seems like the charger in the box charges faster.
reading this thread made me curious, my NOTE II should arrive in about a week, I can't tell for myself yet, what is the A (amps) specification mentioned on the original charger?
as i come from HTC, my current chargers go up to 1 A current. witch is the double A a standard USB port will give unless crossover'd .
thanks in advance!
----
in the wiki thread i found the answer, the supplied charger delivers 5 V 2 A output to the device.

2A! Same as the Tab 10.1 charger.
Filling a 3100mAh battery requires some grunt.
i think even the usb cable makes a difference..
when i use the stock usb cable with the stock charger ..my s3 would charge up comparatively faster than with the other usb cable connected to the same stock charger.:rolleyes

It certainly does! :good:
All electrical cables have some resistance. Very low (but not zero) for quality cables, sometimes quite noticeable for thin and cheap offerings.
From Ohm's Law we know that voltage drop will be proportional to current. A cable with a resistance of just half an ohm will loose about 0.5% at 50mA. That's pretty much nothing. However, at 2000mA the loss reaches 20%.
dude use any charger, just don't use LG charger **** !!!!!
You must use the 5volt 2amp charger and cable provided or a replacement with the same output or youll either be waiting for ever for it to charge or do some damage.
I tryed using my note 1 charger rated at 1amp and guess what? It took about twice as long to charge.
Sent from my GT-N7100 using xda app-developers app
Some of my old 1 Amp chargers aren't happy at all, and will often decide to stop charging randomly.
I though it was something weird with my phone, but after switching chargers it never happened again.

USA official charger
This are the images of the official USA charger that will comes when they release the device in USA
And yes its a 2.0A charger, so the SIII charger isn't appropriate for NoteII.
this is the kind of charger used in Canada, USA, and Latin America, i bought this NoteII in Mexico from an authorized Samsung provider, of course factory unlocked 710usd, like 10,900mxn.
Has anyone tried a 3A charger? Just wondering if this would speed up charging even more than the standard 2A charger.

No, it won't speed it up. It's what the device takes from a charger, and not what a charger can potentially supply. If the device's charging circuit is spec'd for up to 2A current, that's what it will suck out of a charger, not more. You can connect a 30A lab power supply, and it will still be the same 2A (or less) input. To speed up the charging process, you need to mod the charging circuit of the device itself.
I usually have my note3 plugged into normal usb port on my notebook as i work to recharge it just using a normal micro usb cable.. i noticed that re-charges usually take forever and even after 2-3 hours of charging it only goes up only about 10%... is this normal ? my previous phone iphone 2-3 hours on a charger its fully charged.
is there anything i can do to speed up the re-charging like asus ai charger ? or anything else ?
Usb 2.0 is limited to ~ 500ma, the phone will pull 1.2a- 1.5a on the Samsung charger

The ASUS AI charger is for 3.0 only I believe, and your Note isn't compatible with that. I purchased one of the RCA plugs from Lowes that has 4 USB ports on it and has an output of 4.1 or 4.2 amps and using the 3.0 cable that came with the phone it charges it very fast.

Here's what I use guys. I used it on my Note 2, my brother's S3, my Note 3, and also my LG G Pad 8.3. It has about 1.8-1.9A charging capability and charges a little faster oddly enough than the 2.0A stock plug when plugged into the wall. Yes, it's a wall charger, so that's obviously the best way to charge. It's cheap and very convenient; the cable is actually quite long, which is much nicer so you have more room to move around when charging. You won't be disappointed. I don't advertise garbage products. I always look for the best quality things and share my results and opinions to help others. Before my Note 3, I had rooted my Note 2 and had Perseus kernel; I increased the charging values so I could utilize faster charging, and this charger was the best for that. I highly recommend it. I've had it for about almost 11 months. It has never given me any issues, and it has great reviews.
So what is the max that note3 will take?

Hey Peeps
Anyone else getting slow charging on SM-T810?
Using the bundled charger, I am getting average of only 680mA .... Definitely nothing over 950mA and that is even when screen is off...
Using the same charger and cable on my sony xperia Z3 easily achieve 1400mA ...
Same sort of numbers with other chargers etc... So pretty sure it is device not charger...

I just tested and am getting around 1500 mA. That is with my nexus 6 charger.
Bundled charger gives me around 1460 mA.
Are you certain it`s not the app that is wrong as the S2 is new and the app might not have been updated yet, Try the Samsung charging app below, you have to keep pressing the refresh button on the free version.

The charging rate can be anything from 300mAh to the maximum the power adapter can output, the tablet will determine the amount of power it will accept, and will jump from fast to slow charge depending on how much more power is needed until it reach 100%.
Thanks guys - obviously does not seen to be wide issue.
I tried the Samsung app above ... Sort of showed similar values ....
I did a charge from 69% to full and it took about 1.5 hours... So would be maybe 5 hours to charge fully?? Unless the device does much quicker charging at very low battery??
I will do a full discharge down to say 5% and then charge from there and see how I go.
Thanks again

I would install battery monitor widget from 3c on the play store.
A pretty comprehensive battery app and will give you a full history and time line of charging and discharging cycles.

Normally it will trickle charge slow once it reach approximate 80%, and is normally fast if the unit is almost power empty.
It's annoying. I've tried both ipad chargers and a 2.4A charger, but it will go to slow charging mode with anything else than the bundled charger.

Yeah i have found exactly the same!! Must be some sort of Samsung handshake protocol...
There is another thread on this that I have mentions about this, just use a good quality charger, or just go for a Qualcomm QC 2.0 charger from any known brand like htc, aukey, xpower, lots to name, just searh Qualcomm site for a full list.
It won't used the QC2.0, but all should work just like the OEM Samsung one
the ipad charger should be pretty high quality though, so I don't get why it's being so picky.

If you also followed the tab S thread, it's also been mentioned, Samsung tabs S are also picky, and yes all apple stuff don't work.
Should I rephrase it and say some good quality charger will work, even branded ones like sony may not even work, but my intital testing, most QC 2.0 charger will work.
The issue is that I'm trying to find one charger that will charge both my tab s2 and my iphone 6+ quickly. Any idea how qc chargers fare with iphones? The bundled tab s2 charger only gave my iphone 0.4A (it charges the tablet at 1.5A)
I have both sony and asus chargers with included cables work perfectly with iphones and sony xperia z3 and nexus 7... Hopeless with S2.... But s2 charger works fine with them..

Odd, my old Nexus 7 2012 charger fast-charges my S2 710 without any issue at all. I had it spare as the N7 died on me (the S2 is its replacement) and was initially wondering myself as I had a few supposedly 2A chargers at home which only slow-charged the S2 (or indeed under Android 5.0.2 said it wasn't charging at all, even though it evidently was, but 5.1.1 has fixed that).
That said this is a charger without fixed cable (but with a decent USB cable) and I know from Raspberry Pi experience that the cable is almost as important as the charger for getting decent charging (ie enough current) to the device on the far end.
I would make sure the USB cable is a decent one intended for charging.
Proper charging USB cables have the shield connected at both ends for use as ground which is why they are notably thicker.

I agree, a good quality cable is required, as well as the charger itself, I'm using a magnetic cable and a reversible micro USB cable with a OEM Samsung, Aukey and Xpower charger, I don't get the speed of the QC 2.0, but it isn't suppose to as the S2 is not QC 2.0 compatible, but it does charge pretty quick, it also charges my ipod 4, and my nw-ZX2 work without any problems.
I get the "slow charging" message when using the Galaxy Tab S2 bundled charger.
If I use the charger from my Note 4 (Exynos) I get faster charging and no "slow" warning.
Did Samsung bundle it with the slow charger??
I can confirm that samsung did in fact bundle the tab s2 WITHOUT a quick charge usb charger.
I also thought the tab s2 didnt come with quick charge. I have extremely slow charge times but my battery lasts for DAYS... I can fully charge it, put it in airplane mode and check on it after 2 days and be at 98-99% battery.
I also use the quick charge cable AND the quick charge usb adapter that came with my note 5 and the tab still slow charges..
Here the same problem use Samsung charger and cable charge from 20% to 100% in 6 hrs and when use HUAWEI cable with Samsung charger It charged in 2 hrs
I guess Samsung have poor quality cable *-*

I'm just curious how long it's taking people to charge their devices using a QC 3.0 charger. It seems slow for me. I went from 10% to 20% in about twenty minutes. Other QC devices I've had charge much faster than this. Is this normal? It's an Anker 3.0 charger and I've tried multiple cables.
Its taking longer than id imagined based on what id seen about QC3 fast enough though and the phone doesn't seem to get warm. This is using the provided Sony charger which the store told me was a quick charge one. I see similar speeds off my Anker in car charger which is QC3 compliant.
Only ever had my Nexus 5X to compare to (which wasn't QC3 just rapid USB charging) and it seems about on par with that id say.
Using the included Sony QC charger and cable, mine charged from 16% to 70% in 50 minutes and then tapered off from 70% to 100% taking ~80 minutes for that.
Is the QC included? Read a review that it was not. Will receive mine next week.
I think it depends on the region; mine came from Expansys, which I think is the Hong Kong version with a type-G plug (UK), and it did. It only came with a corded hands-free headset, though.
Mine arrived Thursday and I charged it to 100% before turning it on. It was at 5% today when I plugged in the charger. It took 2 hours to reach 100% with the phone turned on but not being used. My phone was ordered from eGlobal Central, Hong Kong. Charger has the Type G plug with Type A, non-polarized adapter.
Cheers!
Got it today, and there was no QC in the package. :/ I live in Scandinavia.
There's a toggle in the settings for the Battery Care mode and from what I understand it monitors your charge habits and slows the quick charge time down during times when it thinks you'll leave it plugged in longer. The premise is that it will prolong battery service life. If you're looking for absolute fastest charge times be sure that's toggled off because it's on by default.
My HK market phone also came with the Sony quick charger. Seller included an adapter for US.
I ordered this: https://www.amazon.co.uk/SAMAR-Charge-Charger-PowerPort-Samsung-Black/dp/B075CFKWNQ/ from Ebay with an EU plug.

I bought a Quickcharge3 from Amazon. Works brilliantly, 2% per minute for the first 30 minutes. Slows down quickly after that. As was mentioned above, there is a battery care option that can delliberatly slow down the charge if it feels it's not in the interests of the battery, perhaps that's what's happening when you are charging. Turn if off, restart the phone and then try again.
Edit: make sure you are using the original supplied Sony USB cable when you are testing. USB C leads are notorious at giving charging problems, especially cheap ones.
Any visual clues if fast charging is active? When using the magnetic load connection on the z3c the 'Fast charging' text was visible.

Using a generic charger my Xperia Z1 have a decent charging speed.
My some apps are open while you charge. They consume a large amount of space and battery.
