Guys I am wandering, can you harm you're phone if it's left on charge overnight on the quick charger? I put mine on to charge right before I go to sleep, then I take it of if I wake up during the night, or first thing on the morning. Is this dangerous for either the phone or the charger??

Nope. Android will charge to 100%, then let it drop to 90%, then recharge to 100. It wont cause damage/fire etc.
Thanks so much for clearing that up for me

I have always charged my phones overnight and it has never done any harm. Looking on the battery monitor widget the Xperia S charges just like everyone other Android phone i have owned, up to 100% full then just remains on a trickle charge.
Be carefull. It will blow up..

I don't know why my phone can only charge to 99% of battery, this is my second charge already and the first charge also can charge to 99% only
Anyone have same problem ?
Just leave it on the charger. Once it reaches 99% charging reduces to a trickle only. This is by design and not a fault. If you charge overnight you should find it at 100% in the morning .

This is renowned in the official samsung roms of the galaxy series. Do not concern yourself, there is nothing wrong with your phone.
so the best thing to do is to leave it like 1 hour on the charger? I find it annoying to .. If it says fully charged and remove the charger it should be 100% and not 99..
Thank you so much. But when my phone charge reach 100% and i leave it continue charge 2 hours more already and it still show 99% right after i unplug charger.
Don't worry about it at all. There is nothing you can do for it to say 100%. No matter how long you leave it on the charger, once the phone says it's at 100% and you disconnect it will drop to 99%. It isn't a fault, it's what samsung does.
If you want to be really nit picky, you could say that within a second of disconnecting the charger, the phone technically has used some of the battery to stay on, no matter how minimal, so 'technically' with some tiny tiny amount of battery used it is no longer at 100%

Thank you, acttually i came from ONE X, my ONE X take 1 hour to drop from 100% to 99%.
So there are no need to worry about it now. And my S3 battery was great. It can last from morning to night with heavy usage.

Leave your phone on charge, go to CWM wipe the battery then reboot. It should go back to 100% shortly. That's what I did and it worked!
Reason why it really doesn't charge 100% is to protect battery as li-ion batteries should never let completely empty or full as the battery can die.

Mine charged to 100% and never have this problem with my S2
This is frustrating isnt it!
Also has anyone else found that it takes longer to charge than other phones? I.e. my S2?
Im presuming this is due to the bigger capacity battery
battery can only ever be 99.999999999999999999999999999% after you unplug the charger!!!!
not another one....

Mine charges to 100%, dry wiping battery stats. Though to be honest. It drops to 99% the instant I unplug it.
To avoid my OCD, I just disabled the percentage/1% mods. LOL, it makes me too obsessive.
Mine charges to 100% but drops to 99% within 10 minutes. Need to disable percentage display as well asap lol
I have read much about it. It is probably intentional. to save battery or something like that. Do not be so angry about it 99% it the new 100% haha

Battery only charges to about 95% when it is reading 100% anyway. This is for the health of the battery, can't remember the technical details though.

Hello everyone,I would like to ask you guys about Samsung S3 charging rate which can be considers either slow,moderate or fast.
Well I think my device has slow charging rate,lets say it dropped to 15% of battery,it takes me about 5-7 hours to fully charge.
I have searched via Google,slow charging rate seems like a common issue to S3 owners,yet none of those results show the time taken to charge.
I would like to listen to your experience,as not everyone would charge their device as same as my battery value,so please leave your reply from any value (you think) to fully charge and how long it takes.
Thank you very much,each of your reply is appreciated.
Are we talking USB charging or AC charging here?
Sv: Average Charging Hours
Yesterday it took 2 hours to charge 55% with the ac adaptor.

Max 3 hours to fully charge (0 to 100%) via AC charger.

Remember charge times are going to be affected by battery condition/apps running /syncing etc so a rough answer is really all you can hope for
zero to 100% average time 3Hours .
jje
Average time around 3 hours but not with the Samsung charger, With the Samsung charger I get around 4 to 5 hours and as far as I know I am not the only one. I measure the output from the Samsung charger and I get 4.7 volts. In a way that could explain the long charging hours for the Sami charger.
2 to 2 ½ hours from 5%~15% to 100%, no mobile data, no wifi, no apps running.
~3hours with normal setup. I normally get 1.5~2% standby drain, if that's any help in comparing battery charge rate..

2.5 - 3 hours, from 2% - 100% using the stock charger and USB cable. There is an app in the general forum which tells you at what mAh the phone is charging. Ensure that you're charging at 1000mAh and the charging will be faster.
Edit: Here is the app - http://forum.xda-developers.com/showthread.php?p=36124435
Make sure to read the entire thread to get an idea of the charging current. It's not too long.

Hi guys.
I have an issue on my SGS2. When phone sleeps for some time it wont wake up more. I need to press on/off button and it starts again. Its like phone shutts down. Its not all the time. Maybe once a day.
It happens on all custom roms so its not rom related. I tryed even both siyah and dorimanx and same thing happens. So i dont even think its kernel related. Is there any app that i can use and see what happens when phone shut down?
Thanks

Ok my phone did it again and now fell down from 60 in battery to 20 percent. I think i got an sgs2 with usb port broken?

You got a fuel gauge going on there.
Let it drain till it's off, charge till it's full, remove the batter (all this with the device off) for 90 sec aprox.
Put it back, power on.

Ok i was on siyah kernel. So i pressed reset fuel gauge button. So now im on 1 percent. Will wait until phone turns off itself.

Lol, you love bumping don't ya?
You can drain the batter while phone is off by leaving it aside for 3-5 weeks, got the time?
Now, yeah; that stweak's trick works too.
Fuel gauge is you battery settling in.

Hi,
I'll buy the S3 next month and I have a question regarding the battery calibration. I have read from other forums that It is preferable to leave your battery drop to 0% once every month. Do you recommend I do the same?
Thanks!
No, you'll damage the battery and can corrupt the partition if the phone shuts down unexpectedly. Unplug the charger as soon as it's charged then try to recharge before it reaches 15%

So the iphone 5s and the s3 have different batteries? Since Apple recommends to let it drop to 0% once per month as the OP stated.

Why should I do that?
As I know lithium-ion (li-ion) batteries are not able to overcharge because they have protection.
Are you sure about everything that you stated above?
Search and read for the hundreds of people left in a boot loop with corrupt partitions after their battery discharged, the S3 is not an Apple product.
Li-ion batteries suffer permanent capacity loss from being left holding a full charge or being fully discharged, avoiding either limit will preserve the battery capacity for longer.
