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.

Perform shallow discharges.
Instead of discharging to 0% all the time, lithium-ion batteries do best when you discharge them for a little bit, then charge them for a little bit. The table below, from Battery University, shows that discharges to 50% are better for your battery's long-term life than, say, small discharges to 90% or large discharges to 0% (since the 50% discharges provide the best number of cycles-to-usage ratio).
Don't leave it fully charged.
Similarly, lithium-ion batteries don't need to be charged all the way to 100%. In fact, they'd prefer not to be—so the 40%-80% rule you heard is a good guideline. If you do charge it to 100%, don't leave it plugged in. This is something most of us do, but it's another thing that will degrade your battery's health.
Fully discharge it once a month.
This may seem contradictory, but hear us out. While lithium-ion batteries shouldn't be discharged regularly, most modern batteries are what's known as "smart batteries". This feature can get miscalibrated after a lot of shallow discharges. So, manufacturers recommend fully discharging your battery once a month to make sure this stays accurate.

The only big no no is to constantly discharge to below 5% and recharge . That according to the experts leads to a much shorter battery life .
Yes leaving on charge is a waste .
Wiping Battery stats does not improve battery life .
But all this is an old story posted time and again and bring nothing new .

there is a built in feature that stops charging once battery level reaches 100%. so there will be no harm to your battery. I have doing the same since gs1
My old Nokia 3510 needed a battery replacement after 4-5 years since it only held 3 days worth of charge instead of the usual 7-8.
I constantly let it discharge from 100% (overnight charging) to empty, the replacement battery cost me 5 bucks.
My Galaxy S1's battery has, after 2 years, no observable loss in capacity with overnight charging to 100% and dropping to 10-15% over 1-2 days.
A replacement battery would cost roughly 15 bucks.
I could go on the same about my Laptop, Netbook, Tablet and other devices with rechargeable Li-Ion batteries.
The point is; don't try to forcefully extend your battery life, enjoy your phone. Most people replace the phone every 1-2 years and the batteries are designed to live that long with high usage and deep-discharging. If yours should not or you plan to keep the phone longer, a replacement battery is cheap.

All Lithium batteries have it (and need it) since there is a risk of damage, fire or even explosion when it is overcharged. That's why not the phone but the battery itself has the corresponding controller. Since the controller cannot measure the exact capacity of the battery (only an estimate), it is recomended to deep-discharge and fully charge (charge-cycle) the battery once in a while to reset the controller's counter.
Battery replacement is cheap and easy as abc. That's the benefit of having removable battery. Just enjoy your phone.

Is the small 40%-80% charges better for the long-term battery life?
What's the best way to charge the phone? Like do I charge the S3 to Fully Charged and then disconnect and then use it till it dies or charge it when it drops to a certain percentage?
The S3 uses lithium ion batteries. Try not to ever fully discharge the battery, it degrades the battery considerably. I would fully charge it whenever I get a chance (or up to 90%) then recharge it within the 20-10% range.

Doesn't really matter, you won't prolong the life of it notably in any case. And the small gains are definitely not worth the trouble.
Just use it like you want and replace it in 2 years time. It will have degraded by that time, however you use it (even if you don't use it actually)

You can use it to 4% actually before it's a huge concern. I charge mine around 10% or lower and haven't noticed any decrease in battery performance. Just don't kill it.

No. It won't damage anything. Just know the more cycles, the more wear. Continual bump charging may shorten lifespan. Not what I consider damage.

Just don't let your battery fully discharge or get too low. Always recharge it as often as you can, especially in the range of 10-20. Also, don't leave it plugged in for to long when it is fully charged. Follow these three steps and you should be good.
Hi,
I've read various guides on the net on the best way to charge an S3 (or any modern smartphone).
Some say charge when the battery is at 40% and take it off when it reaches 80%.
Some say to fully discharge it, then charge to 100%.
Can anyone give me advice on the best way to charge my phone (so the battery lasts longer).
Thanks.

Charge your phone when the phone says connect to charger and remove it when it says Fully charged.. this is the best way to charge your phone...
The battery is only supposed to last 50 charge cycles, before capacity is noticeably reduced. As above, don't leave it fully charged and don't let it go below 15%.
Sent from my GT-I9300 using Tapatalk
It wont matter if you leave your phone on the charger when it says fully charged since they have a cut off point so when it reaches 100% it will not continue to put power into the battery. That's why I charge mine overnight because when I wake up the charger is cold so I know it hasn't been charging all night

Point to note on the above reply .
We on XDA first found that users left phone on charge overnight where reporting a dead unit . After a number of these posts it was recognized as what became SDS or sudden death syndrome .
Leaving on charge overnight is not the actual cause of SDS but something i don't risk any more fixes or not .
SDS seems to manifest in 2 distinct ways.
1) Complete eMMC failure. This usually happens over night whilst on charge* - The LED may be lit but the phone will not wake. Subsequent removal of the battery will turn off the LED. You will never get the LED back on. The phone will never turn on again. It needs to go to a service centre and have the motherboard replaced
* Being on Charge is NOT the cause. This is a writing to memory issue and it is more likely to happen when teh device is awake rather than in deep sleep. When the S3 is on charge, it holds a wake lock (so remains awake) throughout the entire charging period, meaning SDS is more likely to occur when on charge This does not mean you should avoid charging your phone. If it's going to happen, it's going to happen

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.

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.

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.

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 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.
http://batteryuniversity.com/learn/article/do_and_dont_battery_table
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
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.
