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.
Hi guys,
i want to ask - my phone charger has got these parameters -
input : 100-240VAC 50-60Hz 140mA
output : 5.0VDC 850mA
battery parameters :
BST-38
970mAh 3.6Wh
isn´t the charger too strong for the battery ?
charging my battery to 100% takes about an hour,sometimes less.
after charging the battery is quite hot.after 5-10 minutes the battery gets down to 80%, and it is stable from 80%.
i am charging just via USB now, because of i think that the charger is too strong and i think it can reduce battery life...?
what do you think ?
Yeah, it is strange.
The battery drains pretty fast after charging to 100% but later it is stable. Although I didn't notice that battery is hot, I think that charger charges battery too fast which is not good for battery IMO.

No, its not charging too fast. Lipoly batteries have pretty tight specifications and the phone switches the voltage itself, for terms of compatibility a usb voltage is used (so less hardware is needed to step voltages from different sources). It also means you can charge from your pc without having a bypass cable like older model phones.
The mA output of the charger doesnt really matter. A high mA means the voltage will be more stable where as a low mA supply could cause undesirable voltage fluctuations.
A lipoly battery cannot be slow charged or trickle charged, the chemistry doesnt work that way. Slow charging could actually cause the battery to explode or in the very least make its performance poorer.
The battery appears to drain quickly in the first 10% but its an illusion caused by the software on the phone which measures the mAh drop. A lipoly battery may discharge from 1200mA to 1000mA in 10 mins and reach a plateau where is holds 900-1000mA for several hours. All that is required is to reset the battery stats so the phone can generate a new profile over several recharge cycles.
As I said, lipoly charge until near capacity and stop. They dont trickle charge, the charging circuit actually switches off. Those people who leave their phones plugged in 8 hours overnight do it no favours as it justs cycles the charger on and off, this could actually skew the battery stats giving a false reading in the first 10%.
The best thing is to charge until full and then remove from the charger, you can always charge it again in the morning before you go out to boost the %. For the best battery life you should maintain a charge above half as this keeps the chemistry from breaking down. Never ever let it go flat! When the phone registers 0% its not, its a safety mechanism and it will still have above half the rated mAh. Charge a dead lipoly and it will explode violently.
Using alternative charging methods of a lipoly is VERY dangerous. People have lost houses or even their lives by fiddling with them. They are not a forgiving as lion, nimh or nicad. With that said lipoly are cheap, reliable, have a small form factor and offer a high output in comparison.
The best device for charging the battery is the phone charger as it has the highest mA and most stable voltage. The PC comes second as most are only rated 500mA and can have voltage fluctuations in the range of 10% or more. Third... Nothing, there is no third - only flames and misery.

Anybody have tips on the subject? I was reading around and read multiple articles on this. Many said do not keep it on the charger after it has reached 100%. This poses a problem, because the G2 will charge from 0-100 in nearly 1 hour and 30 minutes, and i like to keep it on the charger while i sleep. Does the G2 have software to prevent this? It does say to please remove charger to conserve energy when its full.
Any replies are much appreciated

Well i read also that you shouldnt charge it to 100% frequently
2. You shouldnt let the battery charge drop under 20 frequently Before recharging
3. You shouldnt let the battery run out of charge frequently because our battery will get damaged if u do that quite often
so beware of this point
And they said it's not best to let the phone charge over night frequently

I am no expert in this area - but this is what i do and i seem to get great battery life. i just looked, my device has been on battery for 3.5 hours and i'm still at 100% with usage in the following areas...
Google serviced - 29%
Android system - 22%
Screen - 17%
this is with wifi on, approx 5 min worth of voice calling, and several text messages, couple min of facebook and G+. i am not rooted, running stock launcher with most recent tmobile software update (unlocked and using it on Bell).
I hard reset my device once a month (minimum) - not sure if this does anything, but i am a little OCD when it come to my devices.
Before hard reset...
1. charge device to 100%
2. keep device plugged in for ~15 min after fully charged. The unplug.
3. hard reset device
4. once booted, plug device in a proceed to setup and install programs
5. unplug device once complete
During the day...
I always keep it charged up...i dont usually let it get below 75% (if possible). I'm always around a charger/plug at my work.
During the night...
1. charge device to 100% before going to bed
2. before you go to sleep, unplug device and put it in airplane mode
3. when you get up - turn off airplane mode and plug in for ~15 min or so
Again - im no expert, but this is working for me so imma stick to it!
It is not recommended to keep your phone plugged in after it has reached 100%. Only do it when you need an extra battery boost for the day (and that's hopefully not every day).
The general rule is to charge it from 40%-80% and that partial charges are better than full charges.
I really wish people would stop with the "don't keep it on the charger" nonsense which then makes people think they need to micromanage the charge cycle.
Charge early and often. Don't intentionally drain it down to some low percent, just charge nightly and you should be fine. If you're heavily using the phone, try to avoid dropping below 30%. Heavier discharges cause faster ageing.
And avoid keeping it in a hot environment, north of 30C. If it's your car GPS, keep a vent blowing cool air on it, especially in the summer. During the winter make sure a vent isn't blowing hot air on it.
Heat is probably the primary variable in battery life, followed by heavy discharge cycles.
Do whatever you want regarding keeping it charging after it's full. But disagreeing doesn't make your statement correct. I do agree with your statements about heat, however.

battery is battery, just dont let it over heat and it'll be fine. stop trying to squeeze every second out of the battery and enjoy the phone...
I always thought it stopped charging at 100 but when it looses a little bit on the charger it charges it back. I thought that's why it said to conserve energy....as in energy from your house.

It's an established fact that keeping the phone at charged state between 40%-80% is most optimal (causes least stress) for the battery.
But of course, don't let that get in the way of your daily usage routine and cause you incovenience.
Battery is, afterall, consumable and is meant to be replaced.
I'm afraid there are lots of ill-informed people who insist that their batteries do not deteriorate. Congrats to them, they just find the solution that solves the global energy crisis.

--------------------------------------------------------
Li-Ion Battery
(From Wiki) During discharge, lithium ions Li+ carry the current from the negative to the positive electrode, through the non-aqueous electrolyte
and separator diaphragm.[7]
During charging, an external electrical power source (the charging circuit) applies a higher voltage (but of the same polarity) than that
produced by the battery, forcing the current to pass in the reverse direction. The lithium ions then migrate from the positive to the
negative electrode, where they become embedded in the porous electrode material in a process known as intercalation.
Prolonging battery pack life (from wiki)
+ Avoid deep discharge and instead charge more often between uses, the smaller the depth of discharge, the longer the battery will last.
+ Avoid storing the battery in full discharged state.
+ Li-ion batteries should be kept cool; they may be stored in a refrigerator.
+ The rate of degradation of Li-ion batteries is strongly temperature-dependent; they degrade much faster if stored or used at higher temperatures.
+ Li-ion has no memory effect.
+ Li-ion does not need to be fully charged.
+ In fact, it is better NOT to fully charge, because high voltages stresses the battery.
+ Li-ion cannot absorb overcharge, and when fully charged the charge current must be cut off =>
+ To minimize stress, keep the lithium-ion battery at the 4.20V/cell peak voltage as short a time as possible. (meaning do NOT overcharge)
+ Some portable devices sit in a charge cradle in the on position. The current drawn through the device is called the parasitic load and
can distort the charge cycle. Battery manufacturers advise against parasitic load because it induces mini-cycles.
What does that mean to us? Don't use when it's plugged in?
+ A portable device must be turned off during charge. This allows the battery to reach the set threshold voltage unhindered, and enables terminating charge on low current.
+ Li-ion should never be discharged too low.
+ Do not recharge lithium-ion if a cell has stayed at or below 1.5V for more than a week.
Simple Guidelines for Charging Lithium-based Batteries (from batteryuniversity.com)
+ A portable device should be turned off while charging. This allows the battery to reach
the threshold voltage unhindered and reflects the correct saturation current responsible to
terminate the charge. A parasitic load confuses the charger.
+ Charge at a moderate temperature. Do not charge below freezing.
+ Lithium-ion does not need to be fully charged; a partial charge is better.
+ Chargers use different methods for “ready” indication. The light signal may not always indicate a full charge.
+ Discontinue using charger and/or battery if the battery gets excessively warm.
+ Before prolonged storage, apply some charge to bring the pack to about half charge.
+ Over-discharged batteries can be “boosted” to life again. Discard pack if the voltage does not rise to a normal level within a minute while on boost.
Conclusion:
+ A portable device should be turned off while charging.
+ Avoid deep discharge and instead charge more often between uses.
+ Lithium-ion does not need to be fully charged; a partial charge is better.

I've had (and still have) the Samsung Galaxy S2 for over 2 years, and I had to replace the battery a little over half a year ago due to the dreaded battery bulge (I could spin my battery on the table). So yes, batteries do go bad and they can go bad in a short period of time. And yes, if this happens to the G2 with its non-removeable battery, that really sucks.

Just because it is on a wiki does not mean it is correct. Anyone that purports that current flows from negative to positive, is clearly not an engineer, and thus not a subject matter expert (I stopped reading right there so excuse if I'm repeating).
Heat, be it from charging, discharging, or environment, and over discharge, or improper charging are the primary reasons batteries lose capacity. Lithium polymer batteries will lose some of its initial capacity after a thousand or so charge-discharge cycles, but this is very much dependent on the charging rate used to charge the battery. If the charge rate is 0.5C or less, there is much less capacity loss (if any) over time. Charge rates of 1C and over, generate significant heat that deteriorates the cell chemistry over time, reducing capacity.
If I can ever kill my battery enough, I'll throw this phone on my charge profiler at work to see what charge rate it uses.
BTW, my two year old GSII is on its original battery and lasts all day with 40% left at the end of the day. I charge over night with no ill effects, but I never expose the phone to excessive heat.

I slow charge my phone using a 500mA iPhone Cube brick and microUSB cable for overnight charging. Charging this way takes hours. I use quick charge in my car and office if needed.
A good charger should trickle charge once its 100% just to keep it up.

Like I said, I stopped reading the moment they stated the incorrect definition of current flow - if they got that basic tenant wrong, wasn't going to read further. Was not my intent to offend by quoting your post. My comment on the charging overnight was a general response to a prior post that leaving the device on the charger overnight was detrimental to the battery - probably should have quoted that post. In general, leaving an advanced device like a cellphone plugged into a charger will not overcharge a battery - a cheap toy will probably not have a proper charger and CAN damage a cell if left on for prolonged periods.
BTW, I'm an EE and design in Li-po batteries and chargers in my designs and I'm always dealing with non-technical marketing and sales folks to explain these types of details, so I tend to jump in when I hear wrong information (not saying the links contained false information) being discussed.

Does this wall of text pertain to lithium polymer as well? Consdering that is the type of battery in the phone not ion
Sent from my LG-VS980
I am seeing too many battery misconceptions. Let me clear them up.
STORAGE:
Lithium batteries like to sit around 50% for prolonged periods. If you need to power down your phone and store it, do it around 50-60%.
STATE OF CHAGE / BATTERY LEVEL
- It will NOT hurt to keep your phone on the charger. The charging circuitry cuts off power once the Cell hits 4.35 - 4.4v (If it did not, your battery would swell and heat up and then explode or catch on fire or both)
- It is MUCH more harmful to deplete the battery than it is to keep it full. Lithium batteries DO NOT like to go below a certain voltage depending on specific chemistry formulation.
For Example: Chevy Volt electric car Lithium battery is set to stay within 30% - 80%. They are limited to never exceed an SOC of 80% and never go below 30%. Source: https://en.wikipedia.org/wiki/Chevrolet_Volt
To expand on this. It is BETTER to keep the phone at 95% than it is to keep it at 5% for example. I personally would NOT want my battery falling low enough that it gives a low battery indication (usually around 15%). Usually I do not want it hitting 30%. That's a good rule imho.
CHARGE AND DISCHARGE CURRENT
Lithium batteries prefer to be charged slowly and discharged slowly. They do NOT like high charge and drain.
You guessed it. AVOID high charge scenarios such as Fast Charge. AVOID fast discharge scenarios such as gaming with high brightness etc.
TEMPRATURE
Lithium batteries do not like getting hot. They don't even like getting warm. Getting hot hurts it. Getting warm isn't as bad but it DOES degrade the total capacity over time.
Again, this is usually caused due to high charge or discharge scenarios.
It also ties in with Fast charge, wireless charge and especially wireless fast charge. Wireless charging is not efficient and energy as wasted as heat.
Personally I disable fast charge and do not use wireless charging. Good old USB Type C already charges quickly enough for me.
TLDR: Disable Fast Charge. Try to use USB Type C charging instead of wireless charging. Disable stuff you don't actually use. Try to keep power save on even if using it with very little power saving settings. Try to keep brightness at a reasonable level and not too high (This reduces AMOLED degradation too).
Remember: THE BATTERY IS NOT EASILY REPLACEABLE IN THE NOTE 7 !!!!!!!! Therefore the more you baby it, the longer it will hold it's charge and the lower the chance of the battery going bad.
My old Notes (Note 2 and Note 4) both still have VERY good original batteries because they were well taken of.
Good luck !
But I like fast charging and wireless charging lol
Ironic that when your phone is new, this is when the battery gets hot and used a lot. Perhaps with the water resistant phones we should update the firmware and restore the backup under water to keep the phone cool!
I will be sure to disregard just about everything in here. Guy is spreading false panic.
Actually "store mode" example: found in 7420 kernel source is 60-70% capacity. There are a lot of checks within source including battery swell etc. Don't fret about things, use your device. It's not as delicate as you may think. Who cares about the efficiency of wireless charging. Great if you've got it
90% won't keep beyond 2 years, just enjoy the thing !!

Hello, my Xiamoi Mi 9 is arriving end of next week and I am pretty hyped!
I am really not sure, if I do need these mentioned charging techniques. Apparently you can charge your phone from zero to 100 below one hour. Is it good to charge a phone very often and that fast? Doesn't it heavily influence the battery life? Shouldn't you just use a slow charger and charge it only up to 90%?

Well I don't think the charger influences battery lifespan, it's how you use the device that does
Most phone batteries are lithium ion batteries and honestly chargers (except fake ones) will not harm your battery regardless of charging speed, phones are built to handle them
If you continuously fast charge your battery, it will lower the lifespan of the battery over time. Unless you're planning to keep this phone for more than 4 years, it's not really that big of an issue. But charging speed does affect battery life.
What affects battery life is letting it go to 0% on Lithium. Just make sure you start recharging it around 10%-20% and you will make the battery last for a very long time.
