My phone has 50% battery left. I plug the cable into my laptop to charge over USB. Then I play some games at the same time. The battery level comes up slowly.
So is it good to do that? Or we should do one at a time: charge or use phone.
I have always done it that way and ive had android ever since it first came out. Nothing should go wrong, at least not for me.

Yeah this is a good question I have always wondered about it... Won't it affect the battery like long term?
Wont harm anything
it doesn't matter if affects to the battery or not, you will trade your phone for another new one before the battery gets damaged
The only issue is that the phone will heat up like crazy so...
If you're overclocked or it's a very hot day, please avoid doing this, otherwise you may damage your phone.

Using while charging overheats the battery and the mobile itself.
Heat is the biggest enemy of batteries (wrt. longetivity), so yes it does reduce battery life. Having said that, most of us upgrade phones in less than 2 years, so it wouldn't be as much of a problem.
But overheating is not good for rest of the phone hardware.

I really doubt that. If the phone or battery were overheating, you wouldn't be able to touch it.
Maybe it reduces battery life, but that can't be much, since the battery gets hot whether it's being charged or not.

If you left it in all the time, yeah, that would.
Using it while charging is fine. Mine charges at about 30-35*C, gaming on top its up to max 41/42. Thats well within limits and its going to have negligible effects on the battery pack.
What charger? Sure it was an dealextreme charger.

Deep cycling is really bad for Lithium-ion batteries. I don't know why people keep perpetuating this myth that you should do this after burning a ROM. I blame Team Whiskey et all, etc . . . blah blah (You flashed our ROM now recalibrate your battery)
Lithium-ion batteries do not have a memory, you do not need to deep cycle them like Ni-Cad, doing so seriously shortens the lifespan of the battery. So unless you notice that the readout for the % of battery charge seems very off from reality don't recalibrate. Even if it is off a little, it will fix itself over time as you charge and use your phone. You don't even need to let it drain a lot. Just use it like normal and charge it when ever you get a chance.

Um, just Google search Lithium-ion. Read a little about the battery technology for yourself and you will see why it is very BAD advise to deep cycle your battery. After a little more than a year with Li-Ion the battery will only hold about 70% of the charge it held when it was new. Keep deep cycling and you will shorten that time to about 4-5 months. Then these same people come back here and ***** about how crappy their battery was because it only lasted a few months and they will offer as proof that it was always crappy because they had to recalibrate it a frequently. I alway think the same thing to myself when I here this from people, "dumb ass, you killed it."
Hell, the sales rep at T-mobile tried to tell me this crap when I purchased my phone. I asked her where she got her electrical engineering degree with focus on battery technology from. After the puzzled look settled from her face I told her that the advice she gave was about the worst thing you could do to the battery. She didn't believe me, but I told her to look it up on her fancy Google powered smart phone. After she did that she apologized.

Wipe battery stats, does not affect the battery, only deletes the stats saved by the OS. It won't make your battery run faster, or better. These are only STATS saved by the system to tell you where your power is going.
Don't go all psycho about the battery issue. get a cheap chinese knokoff battery from ebay with charger (as I did) and just go out with 2 batteries, even with heavy use, 2 batteries should last you all day. (well, with certain roms, Almost all day)

I am running Axura 2.1 with no changes to the modem or theme and a stock battery. My phone is only about 2 months old but running stock I got about 11-13 hours and now I get 24+ hours when I let it. Normally I just charge it every night anyhow because it does not hurt anything, in fact it is better for the battery.
Nothing uses more power than the touch screen. Keep scrolling pages and your phone will be a hand warmer.
I've noticed deep cycling lithium ion batteries can destroy capacity to almost nothing quickly. Keep a charge on it whenever you can. The internal resistance is so low, you won't ever notice a "memory." Until the chemistry inside has rotted itself out.

Excellent job of putting into layman's terms the endless cycle of the relationship of heat creating the substance on the electrode that increases resistance, which creates more heat in an endless cycle that is the death of batteries.
In lead acid batteries (like your car, motorcycle, or uninterruptible power supply) oxidation on the plates create this internal resistance and it is why car batteries are rated by number of months, like a 72 month battery. It happens to some extent to all rechargeable battery technologies, but in the case of Li-Ion batteries the internal chemistry actually tear them selfs up over time.
Long story short is the two really big enemies of Li-Ion batteries is deep cycling and heat. In fact if they are not vented well, and allow heat to build up, you get the battery fires you may have heard about with the Dell and Apple laptops that used the Sony batteries. There have also been a few phones that have been known for melting down.
Y'know, I would love to see a big sticky in one of these forums about this. Another voice of reason -- Don't deep cycle your battery, don't cycle it unnecessarily and don't worry about calibration. Your phone calibrates itself all the time and the less often your battery spends any time at low charge the longer it'll last.
Thanks guys good thing I didn't go too far before one of you told me not to do this.

I'd like to ask if an everyday charge will harm my battery.
It's my first week with my phone, and I can't keep my hands off it
As a result, battery runs out every day!! So I charge it...
Will something happen to the battery?
thanks in advance
This phone has a litium ion battery. They don't have a memory effect but in the first time they need some time to become the full potential. So it doesn't matter if you charge the phone every day.

To maintain better battery life it might be a good idea to make sure that u dont fully drain the battery
That shouldn't be a problem the most battery's should have electronic inside to prevent this but I can't guarantee it. You can read also the Wikipedia article about lithium ion batteries it's quite interesting.

I'm glad this thread exists. I'm so used to running a battery down to the minimum before charging it that I probably would have been in that habit for my SGS2. I'd actually come here to ask the same question now I've been through my first four or five "full" -> "red" -> "charge to full while off" cycles.
Is it confirmed both from the SGS2 & LION technology point of view to now keep it charged up, even if using only half/quarter charges etc to do so?
My battery is giving me around 40 hours a time so not too bad but I'd like to keep it running as well as I can.......

Nope. Li-ion batteries these days prefer constant top-ups and full drain actually kills it faster. Totally opposite of what people have been taught over years of NiCD battery use that I've got friends who absolutely refuse to charge their iPhones unless it's at 10% or less. Their loss.

No that's only good to do once in a while. Full discharges daily put stress on the cells and wear out li ion batteries quicker.

Yes it's common for all lithium ion batteries to charge as often as possible. Its true for all phones on the market today and quite a lot of discussion on this is all around the web.
Also a replacement stock battery for any cell phone today is around 20 dollars, so really you can't do much wrong since its so cheap to buy a new OEM battery replacement.
Thanks for the replies. I think this will catch a few people out so hope the thread doesn't get missed amongst all the other battery ones!
Looks like I'd better change my charging habits!
OK so to calibrate my new battery charge to full unplug then use till it dies then recharge to full and that's it? Is one cycle enough?

I know this is slightly a different question. My issue is after you flash a new rom it seems the % is not entirely accurate. It will act fine for a while and then when u get to like less then 10% it drops dramatically like it wasnt reading it correctly or just like today I turned the phone off and did a reboot at 96% and when it powered on it was at 92% which is quite a bit of time on the note 2.
How do you get your battery reading accurate again after you have flashed a new rom? This has happened with my Bionic in the past as well. Thanks.

100-90% can vary depending on when you take it off of the charger. Basically, once the battery hits 100% on the charger, it will start slowly discharging itself to avoid damage. Once it get below a certain threshold, it will charge back up to capacity again.
Regarding rebooting, that process is fairly system intensive and it is natural to lose some battery life. In addition, prior to the reboot the OS is calculating a rough estimate of the percentage left partially based on previous use. So for example, if your phone was in deep sleep for hours, then you reboot where the CPU ramps up significantly, the percentage will alter to more accurately reflect the charge left in the battery.
In short, there is never a need to "calibrate" a battery, the OS will sort it out itself even after flashing different ROMs and it can take a couple days for kernels to settle.
Hey guys
On the weekends I'm usually home and I do use my phone quite a bit..but I'm mostly sitting at my computer doing so.
Is it better for me to keep the phone plugged in or should I be letting it drain? I heard that large drain cycles are not good for the battery and will wear it out faster...I've learnt that with my original Samsung battery...I have an extended one, now.
I've searched around...some people say one thing, others say the opposite...so what's the deal, really?
Thanks,

Summary:
It doesnt matter if you keep it plugged in or not. It will do no damage to it.
What you shouldn't do with this kind of battery is draining it to 0% like some people suggest. In fact it is better to keep it charged above 40% to maximize the lifetime of your battery.

It doesnt really contradict each other. They warn you about heat that is bad for your battery when charged to 100%. Keeping your phone at 100% in a hot enviroment does more damage then having it at 40% in the same enviroment. The same applies to running an app that keeps your cpu running constantly thus heating up your phone.. But in normal circumstances it shouldnt do harm.
It sounds like someone is obsessed about their battery not being at 100% all the time.
Charging and discharging your battery shortens it's life. This is the way it was designed.

Isn't Fast Charging Bad For The Battery?
That would depend on the battery's C rating. Charging at higher rates doesn't necessarily cause damage. There are plenty of articles on charging lithium ion/poly cells out there.
In my previous S7 Edge , the battery lost plenty of juice in just one year of usage ( i was using wireless charging only). Then i sent it to samsung warranty and they replace battery. Tried to find something about if could be the wireless charging that damaged the battery and found none that supported that theory.
Now, with the S8, i´m using the provided charger and cable only (Just to be safe).

Wireless is different due to the losses in the induction, creating heat, which does have some affect. But there are a lot of variables as to why your battery performance may have degraded.

What gets hot? Who said anything about hot?
Hey, don't take it badly, he is just asking. I remember old batteries (for example ni-mh) if you charge it at a high current they use to live less than if you charged them at a slow one (i remember using rechargable batteries of this time for my wii control and i could test it with how long they lasted).
I think the new Li-ion (or better) batteries nowadays don't suffer from this, so you should be safe about them. They have a natural capacity loss thats isnt affected about the rest of the things. You should anyway check for faulty chargers or your battery life, remember all the test samsung makes are with their original hardware.
Regards!

This is someone not knowing what they're taking about trying to talk down on someone else.
Anyways heat has always been detrimental to battery health which is why samsung fast wireless chargers have fans built in to keep the heat low. Along with this the phone will prevent charging if it passes a certain heat threshold I believe 40c iirc and also the phone uses adaptive charging to prevent over heating of the phone with the included fast charger and charging circuit design. As long as the phone continues to regulate the charge coming into the phone fast charging shouldn't hurt. Of course with fast charging you go through battery cycles faster but this is just because you can charge it a lot more times than with regular charging.
My personal experience:
- 2 years of fast charging = battery drain between 100 and 90 very much noticable
- charging over night causes more damage than fast charging
