I have a theory...maybe it was a fluke or maybe its true. I have a 3 year old phone, which I owned from new and has had hundreds of charging cycles, but still has 99% battery capacity of a brand new phone according to both accubattery and measuring with plug in monitor. I've only ever charged it via computer usb 2.0 which is max 500mah.
I've bought some used phones which were only around 1 year old and had just 70-80% capacity left, and yes they supported quick charge. I honestly think the main thing which reduces battery capacity over time is not charge cycles, but charge speed. Ditch the quick charge if you want to keep your battery capacity!
The main thing which kill the battery is the temperature.
And charging faster takes to higher temperature.
But there're some way in the middle.
Charge my 5000mah battery at 0,5A would takes around 3 hours...
Also it should be better charge till 80% not till 100%.

The issue is I think most people have a habit of using their quick charger at night, when it is not needed. You sleep for much longer than the phone takes to charge, even with 0.5a speed. The only time there is a benefit from quick chargers is during the day, but how many people really need to charge during the day if they start with 100%. Some people might never charge during day but still use the quick charger at night.
I think Apples recent change in IOS is more proof of this, so they keep the phone below full charge for a few hours before eventually filling it up. Phones are now charging too fast to the point that battery capacity is reducing noticeably in just a few months of use.
If you are someone who just charges overnight, replacing the quick charger with a slow speed one will definitely help maintain the battery capacity.

I use my phone a lot, also for hotspot often, or when I travel for gps and maps.
(yeah maybe I'm a bit too dependent but still...).
And fast change is my useful.
Anyway Asus set a smart charge mainly trying to optimize the charge speed depending from your habits (with kind of AI).
So if you put in charge during night it should charge slower.
Also in a phone of 3000mah at 60% is kind of not usable. Not the same on a phone with 5000mah.

I'm not saying fast charge is bad, for sure some people can benefit... but the fact my 3 year old phone still has 99% capacity after 3 years and hundreds of charge cycles, and was only charged at maximum 500mah kind of proves that the key to keeping battery capacity is slow charging. I didn't do anything like try to keep it between 40-80% etc, the phone was very often drained to 0% and left at 100% for long time, but still it has retained almost 100% capacity. It must be the slow charging which helped keep such high capacity.

My 4-year device has 3300 mah and it has close to 90% capacity as well.
I think bro, that longest devices are those devices we dont care for.
If you care too much about baterry, it will "drain" faster, and "lose" capacity faster than usual.
Yea, i would agree that main thing which kills battery is temperature, and if you charged that 3 year phone from a computer slow charger, it means it wasnt your daily driver, and it wasnt neccesary.
So you didnt care when it reached 0%, you didnt cared about phone at all, you used it most probably for testing purposes i would guess.
And liion wear out by itself even if you dont use it, if you buy it new and fresh, and store it for 10 years, when you power it up, it will be dead long time, liion chemistry is active and can keep for 5-10 years, no matter if charging or idle, it will bubble up over time, and also if used, from temperature.
I own a new tablet (2 years old now), was amazed with battery, and tought myself (wow, how much i can do with this long lasting capacity), and i unlocked it this summer to custom ROM and full CPU speed all time, readed many books and learned from it, because of strong light in summer, screen was always near max so i can see, and i could feel a strong heat from where led is in lcd, and where CPU is, both sides were frying, i didnt holded tab in hand, i attached a mouse to it, but when i touched screen, it really felt uncomfortable for me, and could feel mild fry on my fingers (i remmember one time, i really burned my finger a little bit, i touched where CPU was), and imagine how much impact it had on my battery.
Even, most of the time, i kept plugged in, day and night, when i am not using it, i always keep it in charger, because i am lazy and dont want one more worry.
And guess what, it still goes good, but still i saw big decrease in capacity.
And i dont worry about batteryes anymore. I keep wifi always on, even when i when not in reach, i dont care, because it is much easier to just plug it in when you can, even when you wake up and see a 10% battery, it is enought to plug it in a charger, so when you go into a wc, and be ready for day, you will have 45%, enought until you go to work, then you can continue charge it. Or even better, buy a battery charger and never worry again.
It's meant to be used, and no matter what you do, it will last 5 years or a little longer, but of course best capacity is at 2 years.

Hello everyone
I was wondering if its ok to leave the transformer connected to the charger.
Is it like the Evo with trickle down when it reaches 100%
I dont want to over charge it. If it were my laptop i would disconnect the battery at full charge. But its not possible to do that with the transformer.
I want to keep my cycle count low and prevent over charing.
I also wonder what happens in a few years when the battery is shot...
Charging is what damages Li-Ion batteries... I'd recommend not keeping it on the charger all the time. Android will purposely not keep the battery at 100% to help avoid some damage.
Li-ion prefer to be around 20-80% charge.
When battery is 100% and you keep the charger connected, heat will begin to build up and eventually you will kill your battery.
I'd do as with a notebook: charge till 100%, then remove battery or charger (in case of the tablet charger ) . Then use your tablet and recharge when needed / desired. And from time to time a full charge / discharge cycle won't do any harm.
Just my 2 cents.
Regards.

They do. There are other threads asking why thier TF's don't show 100% when unplgged from the charger. Same as it does on my Evo.
I think pretty much every modern device recognizes a full charge and responds accordingly. In fact, MacBooks will throttle performance if the battery ISN'T kept in while the system is running on A/C.
Heat will damage a battery, but it's not heat from charging but heat from operation. If a notebook is poorly designed and the battery is near a heat source, then removing the battery might be a good idea (except with the aforementioned MacBooks), but that's independent of the charging issue.
I think it's fine to keep it plugged in. These devices are smart enough to manage such things. Of course, the TF's charging cable's so short it's hard to use when plugged in, but that's a different issue entirely.

From what I understand this process cannot and will not kill the battery. This did happen in the old type of batteries with the ,emory effect but these new batteries and the OS's management system for charging does not allow the battery to be killed.
it will heat up and that would happen as there is a flow of electricity but not to a level that would kill the battery.

IS it normal to go from 4% battery to 99% in under 3 hours ?

Still dont know about it. Because I think its like my EVO and technology got so good that my battery is protected.
I really dont want my transformer to become a expensive paper weight or non-mobile because after a few years it has 45 mins battery life.
I've got the first full charge and full depletion done. Is it ok to use while charging now as long as I fully charge and fully deplete it a couple more times?

batteries will degrade over time....would you be keeping this tablet for over 2-3 years? a simple battery change could work if ever needed
I am no expert, but I have spent some time searching around the internet looking for information on the best methods for improving the life of a battery. Most of the information I have found said it is bad to completely discharge a Li-polymer battery. The articarles stated it was best to charge the battery when it reaches 20% to avoid shortening its life.

Batteries are like muscles - they like to be exercised.
Leaving the unit plugged in WILL NOT HURT YOUR BATTERY. Period. The charging circuitry in modern devices is smart enough to cut current to the battery once it has reached a certain level of resistance.
Batteries do not like being deeply discharged. Most devices will shut off before the battery gets too deeply discharged, but it's never a good idea to tempt fate by running it until the device shuts off.
What really determines a battery's life is the number of cycles it has been put through. A cycle would be a full charge followed by a full (or to a lower end threshold) discharge.
The old original Lithium Ion batteries used in laptops would usually last about 300 full cycles or so - about a year if you used it on the battery every day. Partial discharges of course only count as fractions of a cycle.
Given the life of these types of devices, considering we'll likely upgrade to the next big thing in a year or so, I don't think anyone here will come close to 'wearing out' a battery.

As stated, these are Li-Ion batteries, and they do not need to be trained. The only reason you might need to do any training is to calibrate Android's understanding of the battery (although I doubt you need to do a full discharge for that, either).
It's not going to suddenly kill it, but it will over time hurt your battery's life.
I went ahead and did a full discharge/charge cycle, but only because Asus said to do so in the manual. Maybe the copywriter just copied/pasted from a circa 1990's manual for a device with a NiCd battery, but I figured if they're suggesting it, I might as well do it.
i leave my xoom charging before sleeping, so at some point, it reaches 100% while I'm asleep. I unplug it only when I wake up in the morning.
thoughts guys?

If the guys from motorola only know a little bit about what they are doing, its not harmful.
All devices today are designed with protections against overcharging. I keep mind hooked up to the charger all day at my desk. Don't worry about it.

It is bad though. I know a lot of people who overcharge their laptops and gadgets and their devices stop holding charges. Their laptops have to be plugged in all day and night just for them to be able to use it.
Traditional theory is that you should try to drain the battery as much as possible between charges so you have fewer total recharges. If you are plugging it in every night you are likely to start seeing diminished capacity is 1.5 - 2 years and may need a battery replacement at 2-3 years. If you only need to plug it in every other night, you can effectively double the battery life.

what this ^^ guy said.
The batteries used today don't have "memory" any more, but the materials used internally have a service life, rated in charging cycles.
If 2 XOOMs with identical hardware and software were both used exactly the same, but 1 was plugged in every night regardless of need, and the other plugged in every other night, the effective charging life span of the battery internals would be approximately doubled.
But this doesn't actually answer your question.
No, leaving the XOOM plugged in will not hurt the battery or device.
Li-Ion is actually some what unstable. So the Mfgs incorporate overload protection circuitry into the battery itself.
It keeps the battery from being charged or drained too much.
The Li-Ion will become unstable above and below certain voltages.
Bump charging is an attempt to defeat this system, its like topping off the gas tank in your car.
If this protection fails the battery could overheat and potentially rupture.
I'm sure you remember the exploding laptop battery issues not too long ago?
Hello guys sorry if it is an innapropriate question but I want to know if it is okay to charge my s8+ over night.. does it damages the phone battery or not ? Thanks
I wouldnt. Doubt it would but would but i find it pointless. It charges pretty quick and wouldnt want to leave it charging for 5+hrs The battery is superb i would quick charge a few mins before bed. Ive gone to bed with 19% and had 17% when i woke the next morning.

It's not going to outright destroy the battery, but definitely better not to keep it on the charger. I cannot speak to your schedule and work environment. I charge mine mid day at work. If your usage is generally the same on a daily basis, just find a spot where you can squeeze in a charge or two during the day.
Always changed overnight for ever I can Remeber. Never faced any issues.

1st of all in modern battry charging technology overnight charging doesnt harm battery at all as lith ion batt never get overcharged..bcoz once its 100%(max threshold) charging stop and phone use batt powr
after that once it get around 100% ( lower threshold) it start charging again...

As far as I know, technically wireless chargers are worse for the battery than a wired. They produce more heat, which technically will have a larger impact on the battery. That being said, I doubt there is any appreciable difference.

Good point. Does ths fan cooler on the wireless one prevent as much heat?
The battery retains 95% battery life after a year of normal charging, I wouldn't worry about depreciation. Relax and enjoy the phone
No, you can charge your android overnight as they are smart enough
Boooom! Lol.....just kidding I hope
Stick with the samsung fast charger. I have a lot of other ones, and only the samsung stay cool (fan) and doesn't cycle like the cheap ones do.
Yes, as most have said, you can charge overnight. I have done this every single night for years, on all my flagship devices. Smartphone batteries have technology in them to stop charging when they hit 200% and only trickle charge them. It won't do any damage or won't cause long term battery life issues.
Just turn off fast charge if you're going to charge overnight.

I've also heard the opposite, as wireless chargers charge slower they put less pressure on the battery which helps it not degrade as fast. How much difference it would make either way I dont know, possibly hardly any.
I do know keeping it between 40-80 is widely regarded as being a lot better for li-ion battery degradation than going to 100% all the time or running it really low. Accubattery for example will say you used about 0.2 battery cycles going from 35% to 80%, but 0.92 battery cycles going from 55% to maximum. They are probably just using that 40-80 rule to work it out, but assuming it is correct, you can see how much effect it has, being nearly 5x more battery cycles despite both being around a 50% charge up.
So charging it overnight will get it to maximum, which isn't great in terms of battery cycles. I have seen a couple of battery apps that I think can manage charging so that it notifies you at 80% to unplug it, but I don't think they can actually stop the charge at 80% if you leave it plugged in (althought I might be wrong on that). Again how much real difference it will make I don't really know, and it probably depends how long you plan on keeping the phone, 1 year then it shouldn't be too much of an issue, 2 years or more and I would probably at least try to keep it between 40-80% when possible.
Ha,
Been charging all my phones overnight.
Been using wireless charging since the note 3 and always please it on the charger when im next to it and not using my phone.
Never had a battery problem
Thanks everyone for their answers ..*let the overnight charging begin*
I used Ampere to check how much current was going to my phone when it was fully charged and it read 0.0 so I believe the phone cuts off the charging function when fully charged. As even on 100% without the "fully charged" portion on, it will still show trickling voltage.
Hope this helps. I also advise turning fast charging off at night just to be safe.
So, I own this phone for a few weeks now and I got pretty frustrated about the battery life on this phone as I was getting 3 hrs of SOT a best.
Then I decided not to stress the battery so much by charging it with the included turbopower 25 charger all the time, and use my old (5V 2.1A) charger overnight instead. Then I was surprised to see my SOT going up to about 4.5-5hrs.
I did some research about fast charging techonlogy and found out that when you fast charge you typically don't get as much charge into a battery as with a slow charge.
I still use the turbo charger when I am short on time, but using my regular one definetely does add more juice to the battery, thus, helping it last throughout the day.

Please do report
It doesn't really matter, at least not that significantly... something else is the cause.
Using a turbo charger could change the longevity of the battery, over time, due to heat buildup and breakdown of the internal components due to more stress, but it wouldn't just "get better" switching to standard charger... I charge my phone half the week on a standard charger when at home, and when traveling I use a quick charger. If I am on either at home or on the road for a few weeks at a time and my battery life doesn't change. Well, not because of the charger, but at home I am within 30' of a very high quality WiFi router all the time and essentially never on mobile data, on the road it's the complete opposite.
If you did your researching into Qualcomm's Quick Charge 2.0 (and higher) standards you would see that the issue of batteries not getting a full charge from the original QuickCharge/Fast Charge standard has been remedied with high voltage charging automatically downgraded to "standard" voltage charging during about the last 10% of the charge cycle to allow the battery to cool and take a full charge.

Maybe you're right, I'm still monitoring my battery life on both chargers, and with the same usage, my battery does last longer when charging with the regular 5V one. I'm mostly on 3G network data and rarely use wifi, as I'm mostly only sleeping or eating at home. Maybe there are other factors making this difference, though i'm pretty sure the charger is the only difference for me. Will report if I notice anything else.
I don't see any big difference, I'm also using standard charger over night and quick when I'm in the hurry. Despite charging methods my sot time is very inconsistant from 2,5h to 4h at best.

Charge Regularly
To get the most out of your smartphone's battery, you'll need to charge it properly. Most smartphones have a lithium-ion battery that lives longer when charged regularly. Unlike the nickel batteries used in older phones, lithium-ion batteries do best when kept above a 50 percent charge. Repeatedly allowing the battery to drain fully may shorten its life and decrease its overall capacity. If this happens, you'll need to charge the battery more frequently and it may last only a few hours before needing a charge, for example.
Your battery will also perform better if you don't let it charge to 100 percent, so take it off the charger at about 80 to 90 percent capacity. Leaving the phone connected to the charger when the phone is completely charged may lower battery life if you do it repeatedly.
Actually what happens when you leave the phone connected to the charger is that it stops charging completely. I do not think it affects battery life in any noticeable way, unless you leave it for hours connected maybe.
If you're using your phone quite heavily surely you will be constantly charging if the optimal usage is between 50 and 90% of charge?

What will happen is that when it drops to 99%, it will charge back to 100%. Over the night, it could happen many times. It is a circulating advice for a long time now: don't let your phone on the charger for the night.
I must admit I try never to charge it overnight. I'm managing to get just over a day of use before it needs charging.
but the proof is missing, there are many such fairies in the internet, even if, after 2 years, most buy a new phone anyway. and so long holds each battery! With my s6 I still get over the day. and charge it always over night!

I agree 100% with the above quote. There is no real proof one way or another. It is all speculation run amok.
The only fact is that the battery will slowly degrade over time. THis is what the OEM's want!
They make it very difficult to replace the battery so that you will buy a new phone... plain and simple!
Any phone built within the last two years is more than powerful enough to do anything needed for communications... the reason cell phones exist in the first place. I always charge my phones (when needed) overnight. They all last as long as any other phone.
I too am caught in this ridiculous merry-go-round of buying a new phone all the time because we want to sell them before the battery gets too old.
Progress...argh.
There's a reason why electric vehicles don't use 100% of their battery capacity
But worrying about your phone's battery life is too much of a hassle, I'll have a new phone by the time this one is useless
And since the battery is not user replaceable, it has the same warranty time as the phone. If there are problems, samsung can replace my battery

I agree 100% with the above quote. There is no real proof one way or another. It is all speculation run amok.
The only fact is that the battery will slowly degrade over time. THis is what the OEM's want!
They make it very difficult to replace the battery so that you will buy a new phone... plain and simple!
Any phone built within the last two years is more than powerful enough to do anything needed for communications... the reason cell phones exist in the first place. I always charge my phones (when needed) overnight. They all last as long as any other phone.
I too am caught in this ridiculous merry-go-round of buying a new phone all the time because we want to sell them before the battery gets too old.
Progress...argh.

See above.
S6 is only $150 on Swappa. Mobile phones have $h1t for residual value. Trading up to the latest and greatest isn't something everyone can afford to do every 2 years.
So, what you're saying is, in order to keep my battery from only lasting a few hours and having to charge it more frequently a couple years down the road, I should start to only use my phone for a few hours at a time and charge it more frequently right now....
How much will the battery replacement cost at Samsung?

Charge Regularly
To get the most out of your smartphone's battery, you'll need to charge it properly. Most smartphones have a lithium-ion battery that lives longer when charged regularly. Unlike the nickel batteries used in older phones, lithium-ion batteries do best when kept above a 50 percent charge. Repeatedly allowing the battery to drain fully may shorten its life and decrease its overall capacity. If this happens, you'll need to charge the battery more frequently and it may last only a few hours before needing a charge, for example.
Your battery will also perform better if you don't let it charge to 100 percent, so take it off the charger at about 80 to 90 percent capacity. Leaving the phone connected to the charger when the phone is completely charged may lower battery life if you do it repeatedly.

Charging your phone to 100% won't harm it. Letting it die at 0% though can harm it. Lithium-ion batteries don't like dying, but charging them to 100% won't hurt it, in fact leaving it plugged in for hours, even days afterward, also won't harm it. Chargers stop charging devices at 100%. Phones will be fine as long as you don't let them completely die. If you've ever wondered why they will still tell you the battery is "dead" when trying to power it on after it dies, that's because it's not "dead" so to speak, but the phone shut off to prevent damage to the battery.
In short, letting your phone die CAN harm it, but usually, it won't, because phones power off with some power left in them due to a "dead" battery, to protect the battery. This is why once they die you can still hold the power button and it will tell you its dead. Finally, charging your phone to 100% won't hurt it in any way, as chargers stop charging devices after they reach 100%.

WRONG.
Lithium-ion suffers from stress when exposed to heat, so does keeping a cell at a high charge voltage.
Most Li-ions charge to 4.20V/cell, and every reduction in peak charge voltage of 0.10V/cell is said to double the cycle life. For example, a lithium-ion cell charged to 4.20V/cell typically delivers 300–500 cycles. If charged to only 4.10V/cell, the life can be prolonged to 600–1,000 cycles; 4.0V/cell should deliver 1,200–2,000 and 3.90V/cell should provide 2,400–4,000 cycles.

Too many users have no idea about the facts of Lithium-ion batteries, sadly. Don't spread false information, learn the facts. Charging to 100% IS stressful for any Li-ion battery. The last 10% are the most stressful when charging. That's why Sony invented "Battery Care" which will charge the last 10% very slowly exactly for this reason.

Technically speaking,
A source brought up a couple of months ago says that in a year, approximately 300 charges and/or more, you will lose about 30% of the year. Charging it from 50% and higher will burn out the battery even more. It's better off letting the phone go to a certain threshold of ~>15% of the battery, then charge it so it could have more longer life in these years. Its beneficial for longer life, but day to day wise no. But long story short, i don't really agree with the method you recommend us doing.

This is incorrect. When your phone fully dies then charges to 90-100%, it does a battery cycle. This cycle is worth doing from time to time to keep the safety of your device and battery from not overheating.

They Discharge Batteries too much with 3,0 Volts aka They do put too much Stress on them, bad for BatteryLife and Security depeding which Chemicals are used (INR, NMR, IMR etc). With
*18650 Li-Ion`s thats 0,2 Volts above the critical Boom Limit. Normally the safe Zone for Battery-Life and Security is 3,15V to 3,20V min.
*18650 Idustry Batteries which are used for Highdrain-Usage (Up to 35 Amps) like Battery-Scredrivers (And other Tools for Work), RC-Sports and E-Zigarettes.
