The S2 takes forever to charge the battery. Coming fron the iphone 4 i suspect this takes ay laeast twice as long to charge!
Considering the battery performance isnt that great, this is a double whammy!
What do you guus think?

Yeah, I noticed the same thing. I'm always charging it when I'm at home to keep it fully charged, in case I'm going out.
charging takes me about 3hours (from empty). It is stanrard time
Same here for charging. Between 3 & 4 hours. But battery life is getting better especially if i disable 3G and wifi

Im using nokia charger 1.2A and HTC charger 1A and also i have 0.7A all of them takes about 3 hours may be hardware bug?
I've been using a BB charger for it, and thought maybe that was the reason. Glad to know it isn't.

Yep, I confirm.
Charging takes around 3 hours.
I can use it almost 48 hours before it needs to be charged again. So it is not really annoying.
Stock SGS 2 with official battery charger and a full drained empty battery 3.5 hours to charge to 100% .

About 3 hours here which is fine, charging from the supplied charger connected to electricity mains. Are you charging via the USB connector? It will take a lot longer, something called trickle charge or something like that.

No it takes the normal time but if its to slow for you dont drain it or sell it .

I noticed this when my brother bought the same phone. His takes a ridiculous amount of time to charge, maybe 1% per 10 mins or so and it gets really hot while doing so.
Mine on the other hand doesn't get hot at all and charges at least 3 times faster than his.
please state charge state, ages, fast normal etc.
firmware and revison thanx
The charger shipped with my S2 has only 700mA...
especially if you are using the phone (worst: gaming) while charging it seems to get never finished . I guess the current drain doesn't left much for the charging.
So i'm using my old HTC-chargers (one AC=>USB and AC=> MicroUSB) witch both supplies 1000mA.... ~43% more in theory
Hard to say how big the advantage is in fact, but it makes a difference.
Also keep in mind, that a standard USB-Port supplies max. 500mA, depending on other USB-devices even much less. I also read that the charging result is "better" if you not using it in the meantime.
You can buy USB-Chargers up to 2100mA (e.g Amazon), but i have doubts that this will be improve the charging time because on the type-label behind the battery is written Rated : 3,7V-1000mA. Even more current wouldn't not damage the device (afaik!!!), the device or the battery could not charge faster.
Maybe somebody knows about what is meant by the the 1000mA exactly. Would be nice if the device could be charge a little bit faster.
Otherwise i am going to buy a 2nd battery with an external charger.
greetings
I found this on Android Forum

USB charging is slow on the S2 as it uses trickle charging
"Trickle" is an exaggeration.
The phone can tell whether it's connected to USB or a mains charger. If the latter, it limits charge current to 650mA. If the former 400mA.
It will charge faster on the mains but not loads faster.

I usually sleep more than 3.5 hours per day so I don´t see any problem in the charging time

My other cell phones are fully charged in 2 hours, more or less. And yes, I'm considering selling it, because I like to use my gadgets and the SGSII doesn't admit an intensive use without running out of battery, unless you have a second battery.

Yeah, I do sleep more than 3.5 hours per day and I try to charge it every night, but the problem is when the phone runs out of battery in the middle of the day and you don't have 3.5 to spend in charging it fully.
I think the iphone 4 is only a 1420Mah battery if I remember correctly while ours is 1650. Sure, it takes perhaps another hour to charge but I don't find it a big deal. It does appear that the first 50% charges faster then the second half as well but that could just be my imagination.
I have read that Samsung phones charge slower so that the battery life will be longer than that of those other phones such as HTC where the phone charges a lot faster. I'd rather get another year out of my battery and it take longer but do admit 3.5 hours does seem like a while.
this topic has been covered. teh SGS2 battery driver is capped at 650 mA for wall charging, 450 mA for USB charging. this code resides in the battery driver.
someone could compile a new kernel with this value raised. other phones like the nexus one charge at 980 mA for wall charger, 480 for USB.
samsung capped charge current, likely for heat issues, nobody really knows.
same. take long time to charge and heating if charge n gaming. the hottest spot at camera side

Hi, I got my Defy today. I put the mobile for charging 2 hours ago. I'd like to know for what period should I put it for charging as it is the first time for optimum performance of the battery..
I tried searching the forum for a similar question but didn't find any. Please delete this post if it is a an already answered question.
Doesn't matter. May be charge it for some 2 hours more. You can't overcharge the battery - it has protection. For optimum performance, just don't drain the battery to 0%, although it has protection for this too.
Ok, thanks, its already been 2 hours since the battery reached 100% mark. Will stop charging now.

Although it is generally said that a new battery should be charged for at least 8 hours before use, it may not be necessary. Just fully charge it. However, the capacity may be lower and unstable at first. If charged too quickly, just take it out and reinsert it, and connect the charger, again.
What I normally do is charge it till 100% and disconnect.
Then every month, I'll use up the battery till it shuts itself down, turn phone off, charge it till full.
Any other time, will plug into mobile charger whenever I'm in the office till it's 100% and use it thereon.
Both answeres after mine, are for the old nicd batteries. For liion batteries it is bad to overcharge and discharge to min. Anyway, as i said, there is soft and hard protection for this, so n.p.

Under NO CIRCUMSTANCE!!! I MEAN NONE! that you allow ur batt to goto 0% or you will be effed royally by Defy. I and many others faced this. If your battery is like 15% you either charge it instantly by USB or if you have no means then just turn it off and charge in wall charger when you go home. Just don't ever let your defy goto 0% battery because if it does, you like me and many others will be stuck to M logo or white LED ****.

your lucky bro! don't do that, i was like you all naive and my defy was fine until one day, that happened to me. It didn't turn back on when i tried to recharge it only White LED or M logo.
I didn't even do any flashing or rooting of any kind on my defy then, heck i was on 2.1 eclair. So, be careful and heed my advice or one day you will regret it like I am now.

Use juice defender for added improvements from first day.. i get 2x boost , to save those extra bits when most nedded .. as for ur question , you need to calibrate your battery in order for it last longer
I advice u to charge 100% + 2hrs , and then discharge it to 10% or lower Without charging it in between !,
To full chagne the battery, need more than 10 hours. Tried different ROMs, Batteries, changers, cables. the same result.
It looks like a hardware issue...... but....
when I used a DC power supplier(5.2V, limit to 1A) and plug in the cable, it appears the DC current is 0.5A, and after 10 second, fall down to 0.1A. at least, in the first 10secend the hardware worked all right...
Do you use the original OEM charger ?
Have you tried a different charger ?
How old is your Note ? Have you tested a different battery too ?

I was quite surprised when I switched to the Note from the Dell Steak. My old phone would charge much quicker. The Note takes about six hours to fully charge I'd say. As a result I plug it in pretty much whenever I can.

Yeah, Mine can take around 5+ hours too if im charging it from <5%
Bear in mind that it is a bigger than normal battery, 2500mah.
But if it is like you say, Taking 10+hours to charge, Id get it looked at, Maybe send it off for repair or something.

Isn't it bad to constantly charge your phone even when it still has battery?
I heard it reduces the battery's life span.
I dont believe it is, I often charge mine even when its got plenty of juice left.
It may reduce life span, But the battery will live longer than the time you will own the phone so i guess it dont matter
No one can help. feel bad.
I saw sevral links saying same problem, but no solutions... poor us...

From what I've read, it's what you're supposed to do with the current generation of batteries. But then there's so much crap floating about about batteries it gets hard to figure out what is reliable info.
And this is with the original charger? If it's not an official charger, there's a big chance the phone will draw only what's usually allowed across USB. Which isn't much... In fact, with USB, the power draw of GPS/screen on/games can make your phone discharge even with the charger on. So try the official charger, on AC power.
Same problem...
I have the same problem.
At the beginning, about 3 months ago, my SGN works fine, battery are charged to 100% in 2 hours maximum.
I'm buy the phone from a Samsung Store, all accessories are originals. Today I send my phone to the technical assistance and there's no problem with battery or the charger.
My problem stars about 3 weeks, with an alert about different voltages after a full charge, the problem was solved only removing the battery and waiting an hour. At the technical assistance, the answer was to charge the phone when it's shutdown.
I already try that, format the cache, rebuild the system, everything using the ICS LQ3 from Baltic.

Is the problme solved after remove the battery for 1 hour?
paddyzou, the problem with the wrongs voltages, yes, my steps to solve this:
- Full discharge
- Shutdown of the phone
- Remove the battery for 1 hour
- Full charge with the phone hang out
The problem with the low charge I think that was okay, it's seen to be happen in random times, I just flash another LQ3(France) version of ICS yesterday and seems to be working fine.

This is correct, a chemical reaction takes place while the battery is discharging and is reversed when charging(changing). The chemistry of the battery changes how they hold energy. The Lithium ion batteries in our phones can be charged any time, they have no "memory" characteristics like previous rechargeable batteries (NiCd).
OP, it sounds like your charger is going. My stock HTC charger (2-3 years old) now only charges at about 40% the speed, which means the phone will discharge while its plugged in. I recommend grabbing one of those tiny square usb chargers (1A 5v, not 0.5A). I got one for like $6, as long as its 1A it will be quick.
i had my Note 3 for just a couple of weeks ago, and i found a weird problem the phone charging is perfect till 95%, From 95~100% it can takes like 30~50 minutes !!!!! i don't know whats wrong
So could you please help me guys with that

My phone took around 2hrs to complete charge. If your phone took about the same time then it could just be a software glitch. Try factory reset or reflash firmware.
If it took obvious longer time let say 3hrs or more then it could be a hardware problem.
I reflashed the official rom poland one 4.4.2 but still has the same issue
Charging li-on battery gets slower towards the end of the charging cycle. That's normal. The only thing you should be worried about is how long battery lasts in use. If you have bad battery it charges up faster, not slower then also runs out of juice fast.
Charge with original charger and cable to make sure problem is not there.
I always leave my note charging over night so I don't know how long it should take to reach 100%

Hello mate ,
First of all the charger provided by samsung is never of a great quality . And your grand 2 is charging just a bit slow . It should heve been charged.in about 3-4 hrs. but I guess it can be also a problem of your wall socket . Maybe the voltage must be slow that time that's why it took about 5hrs. to achieve full charge . You don't have to worry . It's not the fault of your Galaxy grand .
Don't forget to press thanks If I helped you in anyway .

There could be problem with wall socket or your phone. Cos mine takes about 2.5 hours to charge from 5% to 100%. Try charging in different socket and see if dat works.

if they have said that, they do suspect the issue with the hardware or else they would have not have given you a new charger. they are hoping that the issue is resolved with a charger. there is no harm in sending the handset to them to check the hardware.

Issue with Charger not with Phone
I had similar issue. It was taking me around 3.5 hours for 100% charging of Grand 2 with Samsung Charger.
I switched my charger to LG charger (I got it with LG L90) and interestingly it now takes only 2 hours :angel:
Hi..im experiencing the same problem as yours with my grand 2..i tried using other samsung charger but the problem still occur..i even plugged it in on other sucket hoping it could be flowing of current itself but..still the same..then what seems to be the problem?!
