Use original Nokia charger that is rated 5V 550mA and your phone will last 30-40 percent longer.
Original SE charger is rated at 5V 850mA, fast charge is not always good.

Hey Seth - Thanks for the tip.
Can you explain why charging slower would affect the overall battery life?
Also, in that case would it be even better if you charged the phone from a usb port (like plugging it into your laptop) which often provides 100-500mA?
Google for "Battery Chargers and Charging Methods" first link for all info about charging schemes and battery chemistry reaction with fast charge and alot of usesfull info.
Just had a quick google -
Fig3 here is a nice graph showing the how fast charging can reduce the overall battery life during the battery lifetime:
http://www.batteryuniversity.com/parttwo-34.htm
This is probably my misunderstanding, but when i read this post originally i thought it was some way to improve battery life as in prolonging the time it takes between needing to charge.. if that makes sense?
partly yes partly no, your link describes charging with higher voltage decreases battery life this is different because voltage is same but current different
example: 3 chargers, our battery is 800mAh in capacity.
5v 400mA - battery charged in 2 hours from 0% to 100% internal chemistry react normal - better absorbtion
5v 850mA - battery charged in little less than 1 hour internal battery chemistry can be little upset cos risen temperature in reaction
5v 8000mA - battery cant quickly absorb this current in chemistry and will propably explode/leak/burn within minutes/seconds
this principle i mean
on usb charging ,battery drains fast for me
try that nokia charger and you will see difference.

That works! I also tested with my brothers' JAGA(!!!) charger mod. 5003fb050040 (5v 450mA) and it was even better.
I have a 5.2A 550mA battery charger of Micromax
Can i use it??????

guys it was 1h 15mins on htc desire. battery draining time feels same but 3 times more charging time.
Mine was left on when charging, but next to no use when charging. Never turned a phone off to charge.
Samsung chargers usually have an output of 700mA at 5v while HTC's have 1A at 5v meaning HTC's will charge faster.
Charging batteries faster with higher amperage chargers does save time, but the batteries also usually discharge faster and will degrade over a shorter period of time than would be the case when using more "mild" chargers with lower amperage.
If you plan on charging your phones at night while you sleep, choosing the lower amp charger will give you better battery life (and you won't have to worry about the fact that it takes 3 hours to charge).

I remember when the SGS was first announced it was put across strongly by Samsung not to charge the phone overnight.
They said it was wrong to leave the phone connected when fully charged.
I have not heard anything this time for the SGS II.
Hi guys,
i want to ask - my phone charger has got these parameters -
input : 100-240VAC 50-60Hz 140mA
output : 5.0VDC 850mA
battery parameters :
BST-38
970mAh 3.6Wh
isn´t the charger too strong for the battery ?
charging my battery to 100% takes about an hour,sometimes less.
after charging the battery is quite hot.after 5-10 minutes the battery gets down to 80%, and it is stable from 80%.
i am charging just via USB now, because of i think that the charger is too strong and i think it can reduce battery life...?
what do you think ?
Yeah, it is strange.
The battery drains pretty fast after charging to 100% but later it is stable. Although I didn't notice that battery is hot, I think that charger charges battery too fast which is not good for battery IMO.

No, its not charging too fast. Lipoly batteries have pretty tight specifications and the phone switches the voltage itself, for terms of compatibility a usb voltage is used (so less hardware is needed to step voltages from different sources). It also means you can charge from your pc without having a bypass cable like older model phones.
The mA output of the charger doesnt really matter. A high mA means the voltage will be more stable where as a low mA supply could cause undesirable voltage fluctuations.
A lipoly battery cannot be slow charged or trickle charged, the chemistry doesnt work that way. Slow charging could actually cause the battery to explode or in the very least make its performance poorer.
The battery appears to drain quickly in the first 10% but its an illusion caused by the software on the phone which measures the mAh drop. A lipoly battery may discharge from 1200mA to 1000mA in 10 mins and reach a plateau where is holds 900-1000mA for several hours. All that is required is to reset the battery stats so the phone can generate a new profile over several recharge cycles.
As I said, lipoly charge until near capacity and stop. They dont trickle charge, the charging circuit actually switches off. Those people who leave their phones plugged in 8 hours overnight do it no favours as it justs cycles the charger on and off, this could actually skew the battery stats giving a false reading in the first 10%.
The best thing is to charge until full and then remove from the charger, you can always charge it again in the morning before you go out to boost the %. For the best battery life you should maintain a charge above half as this keeps the chemistry from breaking down. Never ever let it go flat! When the phone registers 0% its not, its a safety mechanism and it will still have above half the rated mAh. Charge a dead lipoly and it will explode violently.
Using alternative charging methods of a lipoly is VERY dangerous. People have lost houses or even their lives by fiddling with them. They are not a forgiving as lion, nimh or nicad. With that said lipoly are cheap, reliable, have a small form factor and offer a high output in comparison.
The best device for charging the battery is the phone charger as it has the highest mA and most stable voltage. The PC comes second as most are only rated 500mA and can have voltage fluctuations in the range of 10% or more. Third... Nothing, there is no third - only flames and misery.

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
I think samsung made some changes to the microUSB pinout

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
I recently bought a mipow 2600mah portable battery charger for my xperia s and since its my first time to use such device, i have something i want to clarify before i send the product back.
1. The charger promises 2600 mah. Xperia s comes with 1750mah and yet i only get 80 percent charge before the charger runs out. Is this normal?
2. The charger gets really hot after 30 mins or so of charging. Again, is this normal?
3. Does portable chargers work like the phone batteries wherein it gets better after each charge cycle?
I tried.to contact them but to no avail. Perhaps theres someone here who has an experience with portable chargers? Need inputs. Thank you..

I think 2600 mAh os too low for the Portable battery backup. While other comes with 3500+ and even 15000+ mAh,
Portable battery should be 3.5 V [see your battery back side] if it is exceeds it will get hot. If the battery gets hot if can even burst :angel:be carefull :angel:

Is charging time really slow for the Xperia Ultra?
Mine charges about 35% per hour.
It takes 3 hours to fully charge my phone. Coming from a Samsung Note 2 which charges completely in 1.5 hours, I find this really slow.

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?
