Is there any problem if I charge my phone continuously throughout the night ..
I heard that it's not good to do so..is that right?

Yes
It will definitely decrease the life of your battery..
It wont harm the phone as a one off every now and again. Lipoly batteries charge in about 1-2 hours and dont trickle charge. Once charged the phone switches off the charging circuit, when it drops a few percent it begins charging again. Lipoly batteries have a limited number of charge cycles (usually in the region of 500) before the capacity is reduced, if you charge once every day then you get a good year and a bit out of the battery.
The more charging the battery receives the less life it has. If you charge a few times a day then the life could be as little as 6-9 months before it degrades. The process is gradual though and not like a cliff edge, however, as the battery capacity is reduced there is a greater likelihood that it will loose charge quicker and switch the charging circuit more often causing further reductions.
Best practise is to charge once a day until it registers as charged, then leave it ten minutes and unplug it. I always reboot my phone once a day after charging to ensure that any rogue programs have shut down and therefore not causing any drain.
Lipoly batteries last longer when they are holding a charge. Try not to fully* discharge them too often.
*Never ever 'fully' empty the battery, you shouldnt even be able to as it should shut down the phone to prevent damage. (When the phone reads 0% it is still holding nearly 2/3 its charge!) A discharged lipoly battery has a safety cut out to prevent usage when severely discharged as they will explode.

I charge mine whenever the battery drops below 10-20%. So far the battery life is same. Phone is about 6 months old.

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.

Hey, so is it a good idea to charge overnight? I've heard that the charger may overheat and melt the usb port or something like that. So do you guys charge the phone overnight or not?
Sent from my GT-I9100 using xda app-developers app
Its a bad idea.
usually ppl do keep their mobile phones on charge at the night and unplug it off at morning.
recently even i've asked the same question to the salesman of the samsung company he suggestes me not to do that cause it may harm your battery.

Hey, how you doing bud?
You rooted yet? Lol.......
I don't think the phone will overheat if your not using it at the time but it can shorten battery life a little leaving it on charge for longer than necessary, mine doesn't seem too bad with this setup I'm on now my temp never goes over 35° but before this setup i was getting temps of up to 55° when charging and using the phone at the same time. Don't think thats what caused my problems i told you about with chargers burning out though as the last one happened just as i plugged it into a cold phone.
I've always charged every phone I've ever had at night and haven't ever seen battery life go down on any phone i've owned. Not saying i recommend it but its never caused me any harm.

I have charged my phone for 8 hours over night EVERY night since I bought it (beginning of March), and the battery life is excellent.
Last time I looked at battery stats (yesterday) I had 1d 16hrs time on battery and 3hrs 53mins of screen on time, with normal usage.
My normal use is: about 1 hour music, 1.5hours internet browsing, texts, calls, flashing zips etc
So in short, with my experience overnight charging doesn't harm the battery at all

Not yet, will hopefully get to it in the next weeks. Real busy atm. And unlike on wildfire I don't feel an immediate need to do it
Sent from my GT-I9100 using xda app-developers app
you can charge your phone all night, on condition that you must ensure your phone chager is original, if so, you can do it, as the original chager can adjust the voltage of the phone battery. if not, it is very dangerous to your phone.
Thanks for everybody's input. I think I've got our down now Lol. But I'd like to keep the discussion open for anyone that would like to be better informed.

Thanks guys!
Don't run it dead regularly (that was for ni batteries), don't charge it all the time (ie topping off everytime you're near a charger). If going to store powered down for long periods do so at like %60 capacity.

Just to clarify, you saying to not charge when battery it has more than 60% charge remaining? If yes. Then how low do you recommend as to minimum charge left on battery when you plug it in?

It's been a while since I have actually cared about a phone enough to really want to take care of every part of it, including the battery, and I was wondering what the best way to keep it fresh is?
Use until it dies and fully charge every time.
Use until low power warning and recharge.
idk what other methods there are....
Anyway, appreciate any and all tips guys:good:

Best way is to not worry about it. Only thing you want to avoid is letting it die in standby over and over.

Sorry I was so brief was at work on lunch.
In the ideal world you'd probably charge around %20-%30. Lithium batteries do not like being over drained or overcharged. Overcharging isn't really an issue since our phone handles charging. Over draining repeatedly will drain max capacity, same with overcharging. The %60 i refer to is a rough number if you were going to be storing the phone powered off for weeks or months, lithium batteries should not be stored at max voltage or drained.
You don't want to be constantly "topping" your battery off either. The life of a lithium battery is generally going to be measured in charge cycles. So charging it every time you're sitting at a charger will really just wear it out faster.
I generally just charge my phone every night when i go to bed. With as long as these phones last on a charge; I've yet to burn through my entire battery in less than a day more than a time or two. Don't put too much thought into it or worry too terribly much. Running it down once or twice isn't going to do much that you'd immediately notice, but doing it every time is certainly not a good idea!

Okay. Thanks for all the info. It really helps to know that stuff. I'm not to worried about burning through charge cycles. I'm getting 2-3 days of a charge. 4 if I drain it. Battery on this is the best I have even seen. Truly incredible. I don't know how they managed it. But I am absolutely loving it.

The only thing you need to worry about is not letting your battery reach below 14%. Unless your out or not near a charger it's understandable.
Charge your phone once it hits 14%. Let it fully charge don't interrupt it (unless you have too)
Sometimes don't charge your device to 100% I sometimes charge mines to 90%.
Let the battery die once or twice a month.
Just don't worry about the battery. By time you hit anywhere near 500 charge cycles you'll be on the m9 or a new device.

Why would you only charge to %90? And why would you let it die once a month?

Because you wanna train your battery and get the most out of it. A lot of people say those are old rules because these batteries don't have memory cells. But you'll find yourself not needing to replace the battery as fast as you would by just letting it die all the time
I have replaced a cell phone battery yet and I've been using that method since flip phones days

Hhrrmmm. i think you're thinking of nickel based batteries (nicd, nimh, etc). Generally lithium cells really dont like low voltages or have memory.

I think he's correct on the letting it die once every month or so. I did a lot of research on this a while back and ideally you don't let your phone drop below 50% regularly and don't let it sit on the charger all night since its going to be at 100% for many hours before you wake up a li ion batteries prefer to not be at 100%. The discharging it fully will calibrate it and make sure all the cells are being used since if certain cells don't get discharged every so often they start to lose ability to hold a charge. Keep in mind I looked all this up 2 years ago and most of the issues only affect people who keep phones for 2+ years unless the do 100%-0% every day then their battery won't last long.

These phones all have battery protection circuitry built into them.
As the battery approaches 100% charge the charge current reduces to almost nothing to prevent overcharging.
Having said this I would not leave the phone on charge for weeks on end but there is really no reason to worry about taking it off charge the moment it shows 100%.
Likewise for discharge. When the phone indicates that the battery is getting flat it will make sure that even if you run the phone till it dies, the battery will not have been allowed to overdischarge. When your phone switches off software is telling the phone to power down to protect the battery.
Also, to touch upon Lithium battery charge cycles, one charge cycle is the 100% charging of the battery, now keep in mind this can be from 0-100% OR it can also be the sum of multiple chargings up to 100% capacity of the battery
I.e.- charging from 75% to 100% once is not considered a charge cycle to the battery, but do it three more times from 75% (25%x4=100%"rated" capacity) and it considers THAT one charge cycle. So if you charge from 50% regularly, two times charging from 50 to 100% is ONE charging cycle.
