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.

I was calibrating my battery and once it reached 0% shutdown, I fell asleep and left the phone uncharged for 4 hours. Would it have drained or is it safe?
You mean if its safe to use your battery now? It should i would connect your device to the charger and wait 30 minutes i dont think that you can you can turn it on right after the start of charging because its completly empty so maybe you are just able to turn it on when it reached about 5%

No I meant would the battery condition be all right if it was left discharged for 4 hours after automatic shutoff.
no reason why it wouldnt be fine....

These are NOT the days of NiCad batteries and the need for conditioning. You probably did more harm to your battery by taking it to "0". If you find your battery is not holding the charge that it used to, just think back to this moment . Neither LiIon or NiMH batteries need conditioning.
good day.
The battery its designed to shut off and preserve enough power so that it does not damage itself. That said, draining it to 0 increases the likelihood that it could damage itself. The longer at 0, the more likely it discharged to an unsafe level and will have less capacity.
And modern battteries don't need to be conditioned. Rather its the software on the phone which interprets the information the battery gives that needs to be calibrated over time.
Sent from my SCH-I500 using XDA Premium App
So does 0% automatic shut off means the actual capacity reached complete 0%, or does the battery stores a backup battery storage aside from the amount of actual usage?
If taking it to 0% is harmful, then why are people suggesting to reach the 0% automatic shut off? I've always done that after installing a rom for calibration, so if it is harmful then does deleting only bstats at 100% required for calibration solely?
I never do that to my laptop battery since I know that 0 is a full 0 for my ASUS 8 cell battery.
I'm pretty sure all li-on batteries retain a certain amount of power even when they read 0 on the device. The device should shut down when the battery cells reach a certain voltage threshold. This power threshold is unusable by the device but kept to prevent the battery from killing itself The safety circuit itself (present on every li-on battery requires power so the battery will continue to slowly discharge even while off. Therefore it is not recommended to store a 0% battery at that level for any time if possible but certainly not more than a few days. If you wait too long the batter will "sleep" and will not be able to be recharged by most chargers.
All that said, the likelihood that you caused damage is small, but possible. The goal with li-on batteries should be to minimize the time they spend at "stress" levels (either full or empty). Occasional calibration of the device is fine but I wouldn't overdo it as calibration requires you to put the battery in stress areas (and some encourage you to dangerously force drain the battery).
I notice that there's a warning message when the phone is fully charged, advising you to disconnect the charger. I usually leave my phone charging every night, meaning that it's still connected to the charger for hours after it's fully charged. I'm pretty sure that the S2 has "smart" charging, but would the overnight charging damage the battery by exposing it to unnecessary heat for this extended period?
No it shouldn't. Like you said the phone has the ability to shut off the charge when the battery reaches 100%.
I've been charging mine all night for most nights out of the past 3-4 months and it's fine.
That warning is essentially Samsung's attempt to give you a green consciousness, since leaving the charger connected to the wall draws a trickle of current. Sammy figures that millions of people following those instructions to the letter will help save the planet.
It will reduce your batteries life, leaving it on the charger. Will it does stop charging it then drains to 99% then tops it up, which over time uses up the recharge cycles and will reduce the time until it can't hold a charge.
Lithium ion battery doesn't have recharge cycle.

Exactly. This was true until Litium Ion batteries came the norm in handsets.
Nowadays its just to be seen as being 'green'
That is strange since this site devoted to teaching about batteries makes it seem like they do. But also reading it says that being at a constant full charge is more damaging then cycling the battery.
That is in the second paragraph under the "Depth of discharge" chart on this site

With the frequency cellphone batteries are charge/discharged, they crap out after two years anyway, and unlike some other fruity product it takes us 10 seconds to plop in a new one, so don't worry about it.
Even if it damaged your battery the effect wouldn't come noticeable before a long time I think. And in case the battery does get damaged, you can always replace it, that's one of the nice things about this phone, if you compare it for example to an iphone.

exactly why i didn't buy an iphone
The only things really damaging your battery are:
- excessive heat
- heavy use while charging
- turning on the phone over and over after it turned itself off on it's own due to low battery
there are more, for sure, but just to name a few.
I always charge my phones over night and my HD2's battery is as good as ever after 2 years. My SGS2's battery is still the same, and I still thing that when the battery is full there are no discharge/recharge cycles but something like a suspend mode in the charger.
Is anybody having problems fully charging the battery to100 percent? I noticed the battery life has gotten worse since I owned the phone. it would always charge 100 percent. Now it only charges to about 98 percent. I made sure all active apps are turned off and running apps as well turned off. I will turn my phone off at least once a week and fully charge it overnight. I notice after doing this the battery life Is always worse.

Don't believe your battery bar...
Check the number of volts your battery has... its a much better indicator

The phones charges to 100% and then it stops charging if left on the charger. So you will lose 2% or 3% of battery power before it start charging again. This is designed to help keep the battery healthy as its usually not a good idea to leave the phone charging for long periods of time.
I charge mine until the thing on the status bars pops up indicating "full" and then remove from charger. The "full" indicator pops up about a half hour after the phone shows 100% which I find odd however... That also might be a battery health thing as they probably don't want you to charge it to absolute max, so maybe by saying 100% whens its more like 97% that it helps with battery health...

It trickle charges for a while after hitting 100%, then shuts off giving you the "unplug me" notification, drains a few %, then back to trickle charging.
In the morning if you unplug it and then plug it back in it will be fully charged in less than 30 minutes. To the full 100%.
When I first got my phone I was playing with it so much (and testing out the true battery capacity) I was often plugging it in at night with a nearly dead battery - which takes longer to fully charge overnight. So by morning it had only stopped charging an hour or two earlier so it still showed 100% for a while. Lately its been at 60-70% so by morning it has been done for 4-5 hours. So after booting it often shows 98%. No difference in battery capacity, just a longer time post-charge where it has drained a percent or two.

Thanks for all the replies. I guess it makes sense. it just seems to run down a lot faster everytime I turn the phone off and back on the next day. It must just be me

Try the unplug-then-replug routine one morning to restart the charging process. See if it is better that day. If it is, you are probably running into the same problem I talked about in my last paragraph.
Hi guys,
I want to share to those that may be doesn't know how to extend battery for a little bit.
I have tested this method for months and it works well on my D802 G2.
Here how to do it :
1) when you charging your phone and the battery status shows 100% don't unplug your charger yet
2) touch your charger and if it still hot, don't unplug it
3) you can unplug your charger when it is became cold, on my case, it could took around 15-20 minutes later
See for your self, if it could improve your battery life. For me, it is like having a 110% battery capacity.
For best result
Charge your phone while it is off and battery level not less than 15%

Yeah, I got it. i saw when i charged my LG G2 over the night, tomorrow its battery decreased very slowly. But sometime i charged it around 9x%, the battery decreased so fast @@
Yeah right.
I'm doing this since still using G Pro,
100 to 99 = Insane
99 - 98 = At least better than normal
98 - 0 = Normal
I use Android Tuner, you can see what your actual charge voltage is and track when it really is full before you unplug.

i just leave my charger plugged in. when i go to bed, i plug it in, and 6-7 hours later i unplug it. it trickle charges when it gets to 100% anyway. meaning the charge goes down a little and goes back up a little. yes, i guess this wastes more electricity but it is so minor. also the G2 has a capability that when fully charged at 100%, the voltage of the battery is different, so the battery lasts longer at the 100% mark. once it hits 99%, battery life starts to drop at a normal rate. i read about this in another post on xda, forgot where. it used to take me 25 minutes of watching an HD mkv file at max brightness on mx player to drop from 100 to 99. nowadays it takes 20 minutes.
The best results will be if you charge the phone from PC usb port,charge it at night and take it in the morning.
It sounds good. I'll try it.
Thank you!
For best results charge your phone in the freezer.....
Ok just had too
But this is true ^. LOL @woof123, a slow charge doesn't change a thing with these batteries. Fast charge doesn't even get hot enough to be detrimental. The top 1% idea is indeed true. I'm gonna make a slim refillable liquid nitrogen cartridge to place over battery. Win.
Im not talking about battery degration from fast charging,by charging my phone over the usb i noticed that it lasts longer vs the charger.
Just use greenfiy and the donate version
Hibernate every app besides system Apps.
Nothing will run ever again in background while hibernated.
And yes it works and no the app itself does not cause its own drain.
Greenify is highly noted in every forum across xda

With these non removable batteries, I'm more concerned with ensuring that I don't harm the battery. I was reading that leaving it charging past 100 percent might shorten its life span. I've been using. Battery full notifier to avoid doing that.
Sent from my LG-LS980 using XDA Premium App
The general behavior of charging batteries like these is that the first 80% of the actual battery capacity gets charged very quickly (usually takes 1-3 hours) then the last 20% of the battery trickle charges (this also takes another 1-3 hours). I think what's happening here is that the phone itself only reports the first 80% of the actual battery capacity because that's the part that charges quickly, and anything over what the phone reports as "100%" is the last 20% of the actual battery capacity trickle charging.
As for any harm this could bring to the battery, batteries like the one in the LG G2 last longer if you avoid deep discharges (e.g. charging to 100% from 50% at the end of the day versus charging to 100% from 0% after every two days), but it might not even matter since LG Chem's higher end batteries tend to be rated for at least 800 full charge cycles (last year's average smartphones were rated for ~500), which covers over two years of very decent battery performance even if you were to charge from 0 to 100+% battery every day. Even if you use up all these charge cycles, you're still going to be left with ~70-80% battery capacity of the phone you initially bought.
A side note from all this is that any anecdotes of long battery life (where the initial battery percentage reported was 100%) is generally unreliable because it's not conveniently possible to know how much over "100%" the phone's battery has been trickle charged.
My battery life is ridiculously good on this phone anyways...

It's true, 100-99% yields insane use time, but only if you use an app like Battery Monitor Widget to let you know when the battery has stopped accepting power (+0 mA, voltage ~ 4370 mV). It is also true though that this reduces overall battery health a little (it might become noticeable if you do this all the time).
And btw, charging overnight is a very bad idea.

How many of yall use the fast charger overnight? I do have a BlackBerry charger (850mA) which takes like 4.5hours to fully charge, so I use that to charge overnight.
Is it okay to use the fast charger for overnight charging?
I do. I have the phone for a short time (2-3 weeks) But no problems yet.
i charge in the morning for 30min -1h or in the evening to 90%+. i always charge to around 90% for batteryinfo to reset.
While the poco is charging the phone says its better to charge often short instead of overcharging the battery.
To your question, it should be alright to charge overnight. Just make sure it has good ventilation (not on your bed or under things.
If you want to preserve battery life cycle, then no. The closer to 100% you get, the worse it is for battery.
I prefer charging at night and in the morning if it's below 70%.
Otherwise, I will charge in the morning before work, and in the afternoon.
I only charge to 80% where possible
I had a bad experience with LG flex 2, I always used fast charger to charge overnight and with 2 years I got 2 dead batteries. Now I use Battery Charge Limit app and slow charger overnight. It stops charge at certain level like 75%. And that lasts for a full day for me.

I used to do this. But I've noticed that on days I don't fully charge the device, I have to plug in again mid day / evening, ending up using more than 1 battery cycle. If charged to a 100% at the end of the day it'll still have 20-30% left

This could be the result of a few factors.
Does the phone automatically cut off power when fully charged. Most new phones do cut off power or at least slow down the charge rate. If it does not, overcharging is one of the worst enemy of battery longevity/lifespan.
After power cut off, does it resume after the power gets below a certain level, or does it charge at a slower rate. Charging at a slower rate helps but it is still overcharging, so the slower the better.
As I mentioned previously, battery temperature. Fast/quick charging doesn't actually affect battery longevity/lifespan as long as the heat is controlled properly. A phone charging at 50 degrees Celsius at 5 watt (5 volt, 1 ampere) will be dead (unusable) faster than a phone charging at 35 degrees Celsius at 18 watt (9 volt, 2 ampere).

If by battery cycle, you mean how many times it is charged, then true.
In terms of battery longevity/lifespan, then it's not very good.
