Guys my SGS2 is taking around 4+ hrs to charge from around 5% left. Is this normal.?
Yep takes 4 hours here too

What's the rated output on the wall charger?
I think this is by design as the phone already gets extremely hot when pushing the CPU (gaming etc).
I believe this can eventually be changed with custom rom/kernel.

5v @ 0.7A, by the looks of it this is normal.
thanks for responce peps. Never had a phone that took so long to charge.! Normally about an hour which is why i thought i may have had a problem with the handset.!
S2 stock Optus KE2 with it remained turned on with wifi, email checking etc using Energizer XP8000 battery as power source for charge went from 24% reminaing to 100% charged in ~2hrs. S2 internally seems to limit it to <700mah charge rate.
Find a Iphone4 charger or something similar it will give you 5v @ 1.0A, charges quite a bit faster, I use that at work then the slow .7 at home.
my XP8000 charges at 1000mah but S2 will limit it to 700mah
I think you could charge the battery alone in a dock. There it should load with the full 5V and 1ah..

Anywhere you can back this up? I seem to have faster results using a 1.0 vs .7, showing that it is getting more power.
It's been mentioned a few times across various forums. But i'm just going by my experience.
It also takes me around 4 hours to fully charge from below 5% battery. However, if I turn the phone off whilst it charges, goes slightly quicker. Obviously.
Hi,
I think the recharging time is quiet normal for such a phone (and battery).
I had to charge the battery of a friend's phone these days with my notebook.
And it took some hours from 30%. (HTC DHD)
About the same for my SGSII.
I think thats normal.
what would we do without electricity?
Dead phone that is fully discharged battery phone off stock charger to 100%
sub 3 hours .

Changed handset yesterday. today charged new phone from 5% and it took 3hrs 4mins. So it looks like i may have had either a dodgy charger or batt.
I am charging with supplied charger(5V / 0.7A) ...
During the charging I turn off my phone but the charging time is still 3-4h -.-
Hello,
my Galaxy S II is charging extremely slowly. It takes about 2-3 hours to fully charge.
I underclocked it when its charging with setcpu but it still needs so much time.
My Iphone 3gs charged much faster...
Is there any other option to increase the charging speed?
Search would have saved this post .
SGS2 standard charge time 3 hours .

Don't screw with it. Li-ion battery needs a certain charging algorithm and too much current can blow it up.

I think this is normal for our devices, sir. Mine takes that long too and it would take longer (more than 5 hours, I think) if only via my PC's USB port. But don't worry about it. The longer it takes for you to recharge your phone means the lower the power that goes into your battery. With that, the longer your battery will last.
I don't recall the exact specs of the S2's charger. I think it outputs 1amp (or lower). If I want to quickly charge my phone, I plug it into my HP TouchPad's charger which outputs 2amps. I may be shortening my battery's lifespan, but I'm not too concerned. I have an additional spare battery and I'll probably end up replacing the phone in another few months anyway.

What s/he said. ^ Stock battery is around 1600mah. A charge current of 1.6Amps is the most I would go for personally. This should complete the job in around 1hr from completely flat.

Yes:Switch the phone off. Or if you need it on for calls, then switch off the wifi etc.
Better to keep it charging via USB when you are using your pc/laptop if not using it.
Best of all buy an extended battery, then you have no worries...

Correct, purely placebo. Though it would allow you to change USB/MISC charging to 650mA.
Well I bought the Galaxy S3 on the first day of the UK launch and depleted the battery to 0% then charged with the original 1 Amp charger from 0%. I had noticed that this takes a very very long time, around 8 hours. The battery life after charging however is substantial and very adequate.
On the second charge after depletion once again, I decided to use a Griffin 2.1 Amp charger which I had used to charge the hefty Galaxy note with. The Galaxy S3 charges at a much rapid rate and takes around 2-3 hours to reach 100% from 0%. However I have noticed that the battery life depletes a bit faster, Is this due to my imagination or is a 2.1 Amp charger not suitable for this phone as it was with the tablet-like Galaxy note.
Also note that I tried to charge my HTC one X with the 2.1 Amp charger and it charge very slowly, while the original HTC charger has a much lower ampage than 1 Amp
Hmm I have been using my galaxy s charger 0.5amp and it has been charging pretty slowly but seems to deplete faster.
I have been actively using for 50min on wifi now and 85% left. Which seems a bit quick for me. I will try charging with the standard 1amp tonight and see.
Now fast are you depleting at?
I measure my battery life by checking the screen on time just before the death of the charge which was 5 hours on the original charger, with the quick charger its 4 hours. My Galaxy note has no change in battery life weather you any ampere chargers. Also the general battery percentage seems to run low faster anyway on the galaxy s3 using the fast charger.

Just wondering, since the S2 had a limit of 650mA for charging, does this apply to the S3? You guys make it sound like it charges slow as well...
Galaxy s2 does charge very slow for me aswell. Compared to htc phones the Galaxy s 2 charges painfully slowly. Now I regularly use the 2 amp charger on my galaxy s3 and have seen a huge improvement in charging speeds. It charges at around 2% per minute and still lasts around 4 hours of screen time for a full charge.

I noticed that I can only charge fast using original charger. While charger with shorted usb data + & - (ie. htc 1A charger) will not activate fast charging.
You can verify by going into *#*#4636#*#*, Battery, using ori charger will show AC while HTC charger will show USB

Thanx for the "shortcode". Where does one find those?
Also from reading about the MHL to HDMI cable from older devices not wotking, it does in fact seem that Samsung have changed the microUSB pinouts (although my Nokia 1.2A charger shows AC in that battery "menu").
Mine charges from about 10% to full in about two and a half hours, using the charger provided in the box.
My s2 came with a 0.7amp charger and took about 2.5 hours. My s3 came with a 1amp charger and takes about the same. Charges to 80% in no time and then slows down for the later part of the charge

A battery isn't like a fuel tank which you simply fill up through the hose until it's full.
Due to physical and chemical reasons, a nearly-full battery takes a lot longer to fill by a certain percent since it simply can't store the energy quickly enough.
Additionally, deep-discharged batteries often start with a slower charging speed (and then cranked up) to keep the battery from dying too soon and/or not being able to reach full capacity.
is the Nokia 1.2A charger ok to use with the samsung G3 as i got one of these spare and would prefer use it if so as the usb is way to short to reach from my desk up and around the back.
but the Nokia 1.2A charger lead is more than long enough
Just to check with all of you, i've been told that it is best not to charge your phone or any other handheld device IF the battery is not at a really low rate, at least not till your device actually prompts you to charge. They were saying that this would cause the battery life to be shortened. But at times, I need to make sure that i have enough battery to last me for a few more hours before i knock off from work, i would just charge the phone (battery at 25-30%) even before it prompts me to. Is it alright to do that often?
2ndly, at times when i stream videos on my phone for many hours, the battery would definitely drain fast and i would need to charge my phone at least 2-3 times a day. Is it alright for me to do that or am i "abusing" it? =X
Appreciate all your advises...Thanks in advance~
so any update on if using the nokia charger is ok with it being 200mah more than the standard 1A charger since it has longer lead.
or there is the 700mah samsung charger from my old S2

I don't know why this misconception still lives on; lithium ion batteries require no priming on first use. The WORST thing you can do with a li-ion battery is to fully deplete it before recharging. It is much better to top it off whenever possible; having said that leaving it turned on, on the charger once it is full is also not the best thing (though nowhere near as bad as depleting it fully).
I believe since this phone has a removable battery with external charger the best thing you can do is always charge your battery in the external charger and just switch out the battery when it gets to around 10%.
Nek0onna you should charge your phone whenever it's not full and you have a handy charger.

Can anybody check what the max charge rate is on this device with a battery monitor app? I have handfuls of 1A and a couple 2.1A chargers. I'd really like to charge at twice the rate if possible but not all devices support such rapid charging (kernel limits and such). Just curious before I buy one Thanks!
Even if Samsung slipped up and allowed a 2A charge i'd never want to try it, because tablet and laptop batteries are rated and manufactured for a higher current charge/discharge and most phone batteries would heat and swell up and possibly explode.
my HP touchpad charges with a 1A charger and it would be nice to use that with my sgs3.
Can anybody please check what the max charge rate is on this device

The app can only tell how much different the battery is, not how much juice is actually flowing into it. Meaning, the possibility exists that you phone is *using* juice while it's charging, lowering the amount of difference the app can see.

Thread fail. Voltage output, as verified with a Fluke 77 Type IV multimeter, is spot on 5 VDC. Current, which is governed by the phone, has been verified by many to a max of 1900 mA.
I can see just from the screenshots that the app is detailing misinformation. Were your phone actually charging at the rate indicated, it would take approximately 26 days for it to fully charge, assuming no use, from the 76% in the screenshots.
Oftentimes you get what you pay for. Such is the case with Amazon's Free App of the Day sometimes.

I had an iPhone 5 that charged ridiculously fast compared to older phones.
When I'm charging my new S 4, how do I get the faster charge rate?
I'm currently using the Moto 2 USB wall outlet charger that came with my razr maxx hd. And it seems like it takes way longer then my five and I chalked it up to having twice the battery.
Is there a faster way to charge?

The new charger is amazingly fast, if thats a word. I was going to use my.old charger from the s3 at work but its so slow it barely keeps up with use and can't keep up if I'm running my wifi or playing games. Now I just need to find a car charger thats as fast as the new charger.

Keep in mind there's more to it then just the wall charger's output ability. There's something in the S4 that recognizes the original sammy charger and turns up the charge rate yet will only allow a trickle charge on other non-sammy 2.1A wall chargers.
It appears that dome people are aware of this and have managed to modify the non-sammy chargers to enable the faster charge. Then there's some semantic confusion between "quick charge" and "fast charge" features that may be enabled in roms or kernels.
All I know is I wish there were more info on this stuff.
A little knowledge of how Li-ion batteries charge is an important thing. Li-ion batteries have special charging requirements.
The part you plug into the wall... thats not a charger... its a power supply. It provides a 5v DC output at up to 2 amps.
The charger is built into the phone, and it determines how to use that available power to charge and power the device.
Li-ion batteries charge in a two stage cycle that is called "constant current/constant voltage". It is also important to know that a battery's voltage drops as it is discharged. (this voltage drop is how the battery meter gets its information, as it is predictable when tested under constant loads... the variable load of a phone is why the meter seems to be inaccurate at times)
During the first phase, "constant current", the battery is fed a constant current at the same voltage as the battery is currently outputting. As the battery takes in energy, the voltage rises but the current is kept constant.
The second phase, "constant voltage" starts when the battery reaches its highest voltage. (or more accurately, its highest safe voltage, which is around 90% capacity) During this second phase, the battery is fed a constant voltage, (the max voltage) and the current varies. The battery will draw as much current as it is able, and this rate slows naturally as the battery reaches full capacity. When the current drops lower than a certain set amount, the charger stops the charging process and the battery is said to be fully charged. This second phase is slow compared to the first phase, and that is why it can seem like the last 10% of charge takes longer than any prior 10%.
Some phones use the power supply to both power the device and charge the battery, the battery is electrically isolated during charging... but most charge the battery without isolation. Either way, the power from the power supply is being used to both charge and power the device, and this limits the charging speed.
This also limits the maximum capacity the battery can be charged to while in the device, because the voltage/current measuring is less precise. Unfortunately for these phones, the charging is controlled by software, and not simple hardware circuits that are isolated from the battery power. In fact, even when charging the phone with the power off... the phone is still actually powered up but in a low power background mode. This mode is actually a special screen off recovery mode. CWM recovery has had several instances of bugs, where the phone could not charge if the battery died to the point of powering of the device. Because the phone could never power into the special mode to start charging, due to this special mode being missing from, or bugged in CWM.
Also... these batteries have on average a 2-3 year lifespan, and also limited number of recharge cycles. The 2-3 year life is the same even if the battery is unused. As the battery ages, it looses capacity.
Charging at slower rates is better for battery lifespan than higher rates. Now the batteries in the S4 and especially the Note 2 are larger, and 2A is still considered a fairly slow rate, but of course 1A is even better. If you tend to charge only at night while sleeping, it may be better to use a 1A charger.
Awesome explaination !!! That makes complete sense and explains things. The point made in a prior post, about the phone recognizing the new charger, thus charging faster makes sense as well. The new charger must "turn on " the quicker charging on the S3 as well, because it charges my old S3 as fast as my S4. I didn't try the charger on the older firmware but it definetly works with the latest update.

Try charging in Airplane Mode.
Well, there's two sides of fast charging.
One side, you need little time to charge (of course lol)
On the other side, the faster the charge (1,5 hour of full charge on lithiums is VERY fast) the more strains the battery experience in a charge cycle, hence shorter battery life. Since XZU battery is non removable, let's assume that sony play it safe..
Oh and CMIIW the charger for note 2 is rated at 2A DC output right (or was it the S4? I forgot)? That's higher than XZU's 1.5A DC output charger (CMIIW, haven't received my XZU yet).. So 1.5A DC to fill a 3Ah battery is about 2.5 hour, depending on the charge controller of the handset.
- Battery is 3050 mAh
- Charge current is 1 or 1.5 A(h), AKA 1000/1500 mAh
- Charging time for a 3000 mAh battery = (1000 mAh (1 A(h)) x 3 = 3000 mAh), or (1500 mAh (1.5 A(h)) x 2 = 3000 mAh)
TL;DR: It's normal. The bigger the battery, the longer it takes to charge.
You can use a 2 A charger, but it might damage the battery, or worse. Charging through a USB is also much slower (around 500 mAh)

Actually, charging lithium requires specific algortihm to maximize the battery's lifespan and capacity (CC-CV algorithm).
That's why phones manufacturers use "fast charge" marketing gimmick to charge your smartphone up to 80% capacity in just x hour. It is not actually "fast charge". It's just the CC phase, where the charging controller makes full use of the adaptor's output current. After that comes the CV phase, where every lithium batteries, no matter how big their capacity is, are in the mercy of current-voltage law... That said, charging a 3000mAh battery with a 1.5A adaptor will take more than 2 hours.
Technical things aside, charging (most of currently used) phone's batteries from "zero" to full capacity (which, to a certain extent, doesn't matter how big the battery's capacity is) in just 1.5 hours is near the limit of fast charging.
Thanks for the info. Takes me more or less 2.5 - 3 hours.
Now I know it is normal, thanks to your explanations. I was used to the Samsung Note 2's battery (3100 mAh) and it took just 1.5 hours to fully charge. I remember it being 1% increase per minute. Didn't know that the Samsung charger was 2A DC. Yikes, I sometimes use that to charge other devices.

Well for one thing, when you charge the battery, what you're doing is increasing its internal voltage. To charge the battery, you have to supply a higher voltage than the battery currently has, and so the higher the battery's charge, the slower it charges, all else being equal.
However, all is not equal, because at a certain point, the charger slows down the current it is delivering for safety reasons. These two things combine and the result is much slower charging after a certain point.

Weird. it seems that the phone doesn't allow more amps to be transfered. thats ashame cause if you use the phone while charging it doesn't charge almost at all. the consumption is higher than the charge rate
I just compared samsung 2A charger and Sony 1.5A on stock KK 4.4.4 (108). Samsung charger is better if you have limited time.
Is it real that charging with a higher current is bad for battery ?

Debatable, but I don't know that much about battery tech, so i'm not going to speculate. I'll keep using the stock charger though, since the Ultra has an internal battery after all, and I won't risk damaging the battery by using a different charger.
I'm using the DK30 dock btw, and it takes 2 hours from 0-100%. Do you have the dock, or are you using a regular cable?
