i just got this phone a few days ago. i love it. nothing wrong with it.
super fast and everything. im on 2.3.6. no issues. my battery lasts 12 hours easy. and actually up to 26 hours so far.
i dont even feel the need for a custom rom. at least not for now.
but one thing that makes me mad is how slow the phone charges, anyone know why this is ? it's kinda frustrating lol
any way to change this ?
also....i kinda hate that there is no camera button on the actual phone. oh well.
*Edited*
well i dont like to charge unless my battery is on red. so that conflicts, its not always red when i go to sleep. but thanks i'll check it out.
and i dont want to unlock to camera. it's easier to take photos with a button is what im saying

If I remember correctly waiting till the battery is completely depleted is not a good thing for our batteries.
i never said completely depleted though.
and yea ive read so many reviews to not do that, and reviews that say you should... and reviews to charge it this much and that much and blah blah. may be a new phone, but none of this is new to me.
Charge current is hardware limited from what I've read. Or atleast for the time being. If your using the phone while charging it'll be significantly slower. Also using wallplug makes a difference. If you've got stuff running while charging try throttling down the CPU while charging.
Other than that I think our phone is limited to 650mah to charge. So 1650/650 is about 2.5 hours with perfect efficiency. Now take into account the power being drawn and how the chargers for li batteries work, that's about 3-4 hrs to be expected.
And don't run li batteries all the way down on a regular basis, its not good. I'm not positive on li ion batteries, but with lipo you generally want to use about %80 of rated capacity to prolong life and power of the cell.
400 mA on USB, 650 on a wall charger, CPU/screen usage counts against these limits - no way to change this
Forgot where I read it. Could be wrong too.
Slow charging for this phone was samsungs way of keeping our phones battery in shape. Hopefully prolonging the life of it. I noticed my 3GS lose about 20% of its full capacity in a couple years. Only time will tell?
Siyah has an option to upping the charging mA I believe.

all useful responses and all make sense. thank you guys.
i dont use it when it charges and yea it does take about 4 hours to charge.
coming from a crappy xperia x10 which took about 2 hours to charge from 0 to 100
but this phone is 10 times better even without a custom rom so i can deal.
thank you guys for ur knowledge.

He removed it because it turned out not to work. (If it's still there I'm surprised - it should be completely gone.)
It turns out the I9100 has the same limitation as the I777 - charging is handled not by the MAX8997, but by a MAX8922.

If you are on Entropy's DD kernel you should divide that number by 2.85
Battery charge current monitoring (CurrentWidget) support - only reports charge current and not discharge, and reports a value 2.85 times the actual current. Use CurrentWidget's "operation on value" to divide by 2.85.

Hey all,
Since there's no Q&A thread as of yet, I'll be posting my question here.
I'm sorry if this has been asked before, I have searched for it but couldn't find the answer.
My Xperia S just came in today, I started recharging the device when it hit around the 10%.
However, it's recharging so, so slow! Is it supposed to be this slow?
I thought the Xperia S was supposed to have fast charge capabilities?
If so, how do I charge it faster?
It's a Dutch unit btw.
Thanks in advance for any help!

I have a generic UK unit the first charge does take slightly longer. It took around 2.5 hrs after that I got from 1% to 100% in just under 2 hrs. You are not charging via your PC are you?

Nope, using the supplied charger and cable..
EDIT: Also, there seems to be some lag on the home screen and especially in the app drawer.. Anyone notice this?
There are 2 versions of chargers shipping with the XS, EP800 ( less power output ) and EP850 ( More power output )
check your charger to see if it is an EP800, i am pretty sure it will be. The 850 does its job much faster.
Another way Sony is "cheating" on us.... after i got my XS replaced twice in 1 week and already waiting on another replacement it just do not surprise me anymore that things like this happen with this device.
First Flagship from sony alone and it is already a catastrophe

Ah, you were absolutely right. Second charge was way faster.

Yep, it's an EP850. The first recharge takes ages, but the second recharge is pretty darn fast.
I don't have any problems as of yet with the XS, except for its laggy home screen.
Wonder if I'm the only one whose home screen is lagging..
What's up with yours?

is ep800 safer 4 battery? quicker charging = shorter battery life?
more mA -> more resistance -> more heat -> less battery cycles life?

It's no safer than the 850.
The phone was made to withstand the 850 charger (one of the selling points actually was its charging). My phone (Tmobile NL) was shipped with the speed charger, but I'm noticing that after a few weeks the phone seems to be charging fast in general, on any charger...or maybe I am just imagining things?
I have an old BB charger that I use sometimes (I have chargers all around the house from old phones, i swear :/) and it seems to also charge it fast.
Edit: Also, on both chargers, my battery life is just as fantastic at night I charge my phone while I sleep though ( I don't get why you wouldn't charge your phone while you sleep?) so maybe my battery is more worn-in than a lot of people.
My phone is plugged into my " old " desire charger at home, which seams to charge faster than the default one , saying that , I also use my PC to charge ,so maybe the little top ups help + the charger at home .
It does last a while now, however we are running a powerful ( mini ) PC , so we cant expect too much !!
Hello
So my GS2's battery was seriously getting crappy, and I ordered a new original battery (more expensive, but I really wanted it to work properly). Before the replacement, it was all over the place, and I think I may very well have a phone that's seriously confused about its battery options.
Thing is, after the replacement the phone isn't charging the new battery properly (AFAICT). If I'd have to venture a guess, I'd say it charges it to 33% and then it states 100% full.
So, I get just a handful of hours of regular on-time with this new battery. Sometimes the phone hard-dies when saying about 50% remaining, other times it actually says something like 2% remaining, then dies, but still awfully far from logical, considering the fresh battery replacement.
I've searched for how to calibrate this thing, and most results simply recommend the "fully deplete, then fully charge, extract, reinsert, etc." method.
However, this does nothing to help me.
I read somewhere that for some custom ROMs (Dorimanx kernel?) you could do a more "explicit" recalibration, but I'm not sure if that'd work — as I'm on ParanoidAndroid ATM, and here I don't have such option.
So... Does anyone here know of any more "legitimate" way of recalibrating? I really don't want to buy a new phone, as these days I don't see any phone I really want to buy...
TIA,
Daniel
new batteries require a few charge discharge cycles before they reach max capacity, you may need to leave it on charge for longer than the "charged" info appears.

Thanks, Sparks, but I've already done this many times. I've had the battery for a couple of months now, but I really need to figure out how to calibrate the phone so that it starts behaving "normally" with my new battery...
Let it die, juice it up while it's off, take the batt for 90 sec when it hits 100% and put it back in?

No. The whole 'calibrate the battery thing' (and the apps that claim to do it) on the S2 is Kool Aid.

Something definitely needs calibration, and yes, of course it's not the battery itself when buying a fresh original battery does not fix one's battery problems, it must be some battery controller somewhere. I just started a new job, and my CEO has a Galaxy S3 which started having battery troubles. Like me, he replaced the battery, and like me, nothing changed.
In the meantime, my S2 died completely, so problem "solved" I kinda feel retarded for planning on buying a Note 3... Probably ought to run from Samsung devices altogether...

Then buy an ICrap or old BlackBerry and get a swirl... live free with equally fast discharge...
Fast charge is disabled by default (on obvious reasons, google it), but hey... anyone is free to make it work if he can find a proper solution.
Said that, 3 hrs should be more like 2 hours or 2 hours and a a half... but seen OP never stated specs, it's all right.

Yes I am , thank you, cause the slow charge issue was elaborated and mentioned so many time around XDA but seems no one cares to search and read.
This phone with and with original charger, and AFTER teh update from Gingerbread to ICS/JB is charging as per specs. On Gingerbread there was a flaw that permitted to charge it upto 900-1000 mA but the phone was rather hot, I recall charging mine in an hour and a half or 15-20 minutes more, from 2-3% to 100% back when phone had GingerBread.

You can use 2.1A output chargers too, it is simply not going to draw all that but you might get the better on the go recharging while you're using the phone with heavy apps. Just think of the dual car chargers - they have both 1A (phone) and 2.1A (tablet) output. SatNav on 1A is zeroing or still draining your phone battery, while 2A can slowly charge it on the go.
You just give it a needed juice and if the discharge is so greater then recharge, there's not much you can do about it.
Call it a flaw, but Samsung did it cause of longevity of their batteries and li-ion technology.
That is why I indicated iCrap and BB - their fast charge is provoking rather fast discharge too cause the battery will not hold it. I have colleagues with BB who're charging in an hour but get their phones depleted in 3 hours of usage... I wouldn't want that from my S2 for sure. :good:

It doesn't matter what the output current of the charger is... the phone will only draw 650mA.
The charger I got with my S2 delivers 1A but my phone only draws 650mA. Actually the hardware doesn't support it.
IMO, 3hrs is pretty fast for a full charge.
Edit: Just noticed that Fevves already mentioned all that...

Some kernels have the Option to change the charge rate but even at 650mA the phone will get very hot if you are doing something on it while charging

I have Galaxy s2 (GT-I9100) but the problem is that it doesn't take charger, however, the phone is showing charging icon.
Everytime I have put my battery in universal battery charger & it take long time to charger my battery i.e 6 hours 60 % and 8 to 10 hours 100 % and then when I put battery in my mobile & use battery, It is draining very fastly i.e 100 % just finished in 2 hours. :crying:
What should I do? Can you please tell what is the problem & how can I fix it (or from my nearest repair shop).

Hi,
Thanks for your reply, I have already bought a new battery.
Sorry for the noob question, what are you saying "rev" ? and usb port flex?
So, u bought a new Battery, but the device and even the external charger are both charging slow? U should now try to use another Cabel and Adapter (Even if they seems to work).
Also a new battery(Production 2015-2016) shoudn't drain in 2hours, it might a Software issue there too.
For the USB Port flex, just google it and u see what is mean. There are also different revisions, that one you buy must match your phone

Wow wtf.. sorry but u didn't even bought a Original battery and ask for help?! Please.
All 3rd Party battery's who claim they have more mAh than the Original Samsung one while having the same size are pure fake! There is simply no way to fill more mAh in same space.
It *is* possible to get a Samsung original 2000mAh battery.....but it's physically bigger than the one that came with the phone....it'll also come with an extended back cover to accommodate this.
To the OP.....If you got the battery off eBay and it's covered in a gold coloured label......bin it now because it's utter rubbish.....even if the listing stated 'Samsung original' and it looks like a Samsung battery......I can guarantee you that it ain't.......
Unless you brought it directly from Samsung, then it's probably come from Shenzhen in China (or somewhere like that).
That being the case, there's *no way* that the battery is rated at 2000mAh....it's likely to be closer to 1300 or 1400mAh....
Finally...If you do replace the USB board, the advice given about matching the REV version is accurate and critical....Here's a link to a guide I wrote on that exact subject.......
