Does leaving plugged in harm battery?

I turn my phone on Airplane mode and unplug at night while I'm sleeping.
BUT! When at work and at home at other times, is it bad to leave it plugged in 100% of the time? (I.E. does it decrease total battery life over a few years to be constantly charging.)
Or is it better to unplug ASAP when it hits 100% and let it drop to 20-30% and recharge-unplug-recharge-unplug etc? (If so, how much of a difference would this make?)
And does it matter USB vs AC source? I know USB is half the amps, so this could have an effect too?

Honestly, the battery is going to deteriorate a bit either way over a year time span. It is probably best if you just replace the battery every year.

Doesn't matter. All you need to really be worried about is that you leave it on the charger long enough to get a true 100% charge, and you don't always put it on when at 80%, try and run it down from time to time to 10% type thing.
If you leave it on the charger 24/7 for a year, it will have no real effect on the battery that a year of use wouldn't do, and you might actually come out ahead since battery life times are based on charge cycles... when on charger, as you are asking about, there would be virtually no charge cycles.

Ooooh, interesting... Did not know that. I thought that leaving it charging was the worst case possible.

But let's be honest.
How long do you think you'll keep the phone?
I've never had one more than a year...

[Edit]: Well, my thinking is how BAD could this affect it. Like leaving it plugged in all the time = 50% battery capacity in 4 months type of thing. I guess that is not the case though eh?

To add to what pjcforpres said, I would suggest topping off the battery a couple times a day rather than always letting it run down to 20-30% (deep cycling) the battery. Deep cycling is worse for Li-ion batteries. It causes more heat for longer periods of time when you do charge. I would only discharge completely once every few months to keep the battery calibrated.
My personal habit is to top off frequently. If I'm at home, I'll let it charge to a true 100%, like pjc said, then take it off the charger and leave it off till it hits 75-80% and top it off again.

i can add to this discussion what i've learned about lithium-ion batterys
having it plugged in, while it is being taxed heavily (playing games) and already at 100% is a bad idea, then i discharges and recharges all over the time.
When it isn't full and you plug it in to top it off it shouldn't really do any harm, as long as you disconnect it when it's at 100%.
Emptying it completely also lowers overall capacity, 10% is a good threshold when to charge it.
When leaving it off to store it for a while, store it with around 70-75% in the battery. Storing it fully charged also lets capacity down.

I respectfully disagree with creepinshadow's suggestions. I've read up on lithium ion batteries considerably in the last few years. 10% is not a good threshold to always charge your battery from... that's deep cycling and was great for nickel metal hydride, but isn't good for lithium ion. That said, there's no way for it not to get that low from time to time if you're away from your charger for extended periods and I'm sure it's not going to destroy your battery as fast as one might think.
As for storage, the I charge (or discharge) mine to 40-45% then pop it into the fridge for storage. Read that in a long article explaining how to treat li-ion batteries.
Like you said though, a full discharge for calibration is running it till it turns off then plugging it in while keeping it off until an hour or so after the light turns green.

I've heard many people say that leaving any device that has a battery plugged in won't harm it as long as you're consistant with the charge cycles. Like only plug in your phone when the battery life is >15% and charge it to 100% before unplugging it.
I get into trouble there, because (for instance) say I'm going to be going into the mall for a while and my battery is at 30% and it's going to take me 30 minutes to get the mall (I live in Northern Virginia, traffic is a *****, haha). I'll hook up my phone while I'm in the car just to have extra battery life while I'm away from a charger.

good question, i wanted to know the exact same thing so good to see someone else ask. got the answers i needed.

Look guys... the reality is that this discussion is really just academic. Take my recommendations, for example. It would be ideal if everyone could do what the study I read suggested, but it's not practicable to always top off the battery and not deep cycle the battery frequently. That being said, I'm sure the difference in battery life wouldn't be apparent for a very long time. I can't imagine phone and battery manufacturers haven't thought about this. So...while I've posted my "recommendations" based on that study... just enjoy your phones.

A new battery cost <$50 i'm sure... If you left your phone plugged in over night, every night for a year it probably won't hold a charge better than someone that unplugs in once it reaches 100%..
I personally would rather not deal with always worrying about over charging it and IF i still had the phone when the battery needs to be replaced, just replace it.
In the past 16 months i've had the Touch Pro, Palm Treo Pro, BB Bold & now the N1.. so i never have a phone long enough to even care lol.

I guess that's true. We can always replace the battery, unlike the Fruit people!
But I was just worried that the damage happened quickly. But I guess it's 9-12 months before seeing any real effects anyway.

Tips on keeping the N7 battery healthy

Whats your way of keeping your nexus 7 battery healthy? I wanna keep it as healthy as I can for as long as possible. Nothing irritates me more than having a battery lose its charge faster and faster every day. Just to be clear im not asking how to prolong battery usage between charges; I'm asking how to keep it from losing its charge quicker and quicker when the power usage is relatively the same. One thing I do know is once it the battery hits 100% to take it off the charger. One thing i have heard is try not to let the battery dip below 50% and rarely let it completely discharge but I have also heard to ALWAYS let it die out by completely discharging. Feel free to add to the myths, folklore but preferably facts on how to keep the battery healthy and holding its charge very well

N7 has Lithium polymer battery, right?
Well then read about it https://en.wikipedia.org/wiki/Lithium_polymer_battery
But from what I heard: rather charge it then let it drain below 30%, don't let it charge too long, and so on - probably the same stuff you heard or read yourself
but that's something that upsets me: no chance to replace the battery. Used my DHD for 2 years and after those 2 years the battery was just ****ty. Replaced it, works like a charme. On N7 or TF300T there's no chance to replace the battery. Right now I'm using TF300T very often when I'm not at home, so even with dock and tablet it'll most probably go below 20%...well if that's bad for my battery, then I don't know what to do if it doesn't last an entire day :-/ (though that'll take some time)

Certainly I wouldn't let the Nexus battery completely drain but maybe down to 5 % then fully charge

You can change the battery on the nexus 7. Its actually relatively easy and simple to do so. I havent had the need to replace it but I did have to disconnect it. Just pop off the back with your choice of apparatus. I used a small flat head that i could wedge between the sides but a guitar pick is another popular choice. Then just disconnect the wire and take the battery out! no screws just slight pressure holding it in. right here is a guide with pictures showing it step by step.

What I would do is time my charges. In my experience, my Nexus 7 gets fully charged in 2 and a half hours from 20% battery. I then take it out immediately so that in won't get hot(sometimes it does, and also to save energy.:good And also, if after 3 days my battery is still 50% or above, I drain it to 20% then charge since Li-ions tend to not want to get not drained often.xD

Charge early and often and keep out of extreme temperatures. It boils down to that.
If you can, charge it nightly. Try to avoid discharging below 20%.
And a little myth busting... There is no need for you to manage its charging cycle, it will do that itself. Charging a LiIon/LiPoly battery partially is NOT a "charge cycle".
If you're actively using your Nexus 7, just charge it as often as is reasonable, nightly should be just fine. If you're NOT using it for an extended period of time, discharge it to 50%, turn it completely off and store it in a cool (20c/70f range) location.

The battery's are $20 for a new one so as long as it lasts a year I don't mind buying another one. In another question has any one bought a replacement battery yet? And if so does the charge last about the same as stock?

My advice : Charge it when it's between 20%-30%. That's the ideal charge point. Any lower and you're just damaging the battery and any higher is just a waste. As for immediately plugging it out once it hits 100% is utter bull. You see, these modern day batteries found in most phones/tabs have their own resistors which decide how much power enters the battery or if it should enter at all. Once a battery hit's 100%, the resistors kick in and block all incoming power. The "discharging" many believe to happen if we over charge beyond 100% doesn't exist. What happens if you leave a phone or tab alone idly ? It discharges like always. Same thing here, which is why you see your battery bouncing from 100% down to 97%. When that happens, the resistors will allow power back in and thus charging it back to 100%. So you can leave it charging all night and not having to worry about it going beyond 100%. It'll get it's own sh!t together .
So bottom line :
1. Charge when it hits 30%-20%.
2. Don't discharge it (0%) and back to 100%. It doesn't work on modern batts.
3. Don't worry about pulling out when it touches 100% immediately.

Nope. Reboot away. Remember, the only harmful thing you can do and see immediate effects are charging the battery in a very hot enviroment or if you charge it when the battery is 40-50 degrees celcius. It'll either swell up or it'll just catch on fire or explode.

[Q] Best Way To Calibrate Battery

There is no BEST way to calibrate your battery. We all have our own theories.
The stamina mode thing is a semi bug, you shouldn't worry about it.
With semi bug I mean: The phone learns from your daily tasks and then adjusts the stamina mode time to it.
Mine also says 9 hours, with stamina mode 21 hours or so. But I'm not worried because I can get a lot more then that.
When you clear the cache (Dont remember from what service/app) the stamina mode time resets to "normal".

Best way to calibrate your battery, is keep charging your phone when it needs to be charged, and make sure that you followed the charge instructions when you opened the box. Then after about 3 weeks the battery will be as good as it is going to get.

There's an extensive discussion regarding the necessity of calibration in the thread linked in my signature. If you read the first few pages you will realise it is not needed.

Calibration is not require...if your phone die too quick get one of those portable battery charger, it look like a damn tampon, but it will do the job, 2000mah.

No not really. It's a li-ion battery and they just don't need that type of treatment. Alot of people will harp and whine that it does but that's pretty much just people stuck in old ways (sony themselves have a note with it saying charge for 30 minutes before use) . The only thing that's "bad" for the battery is continually jump charging it eg plugging it in to charge at say 40%, only letting it reach 60%, unplug it, use it for a few hours and do the same thing. That and maintaining a full charge for a long period of time or maintaining a very low charge for a long period of time.
However I would charge my S2 every once during the day, then again at night and leave it on charge till the morning. Leaving plugged in for excess of 5 hours every night at full charge hasn't caused any noticeable harm. They have sensors to slow current flow to a trickle when they are at full charge to prevent over charging so I guess that does the trick to prevent it from reaching true 100% charge.
Rule of thumb; when the phone tells you to plug into charger, that;s right about the best time to do so. Later wont matter so much, but earlier and you are basically wasting a charge cycle and shortening it's life.
My S2 is still on it's original battery though and it is still going strong after approx 2 years.
The best way to calibrate would be to stop fiddling and let the phone do it's thing. Reboots and recovery mess with it alot as alot of battery percentage gets lost during both of those and throws it way out. A couple complete charge and discharge cycles without powering down should be all it needs

[Q] things to be done on battery after getting new htc one

I am new in HTC phones. I will get my htc one after 2 days, i mainly want to know about battery charging cycles. how can we do that to get maximum battery life. what is mean by battery calibration ? is the battery to be calibrated in every weak ? sorry for my bad english

Once at month, you have to discarghe the phone at 0%, put it in charge and switch on it when the led is green.
The battery life, during the day, depens of you and your use of phone

Just use it. Charge it when you need to, charge it when you can, top up charge is fine. Calibration is a myth. You don't need to do anything or not do anything abnormal.
Letting it run out and leaving it empty is a bad idea. Charging it, turning it off, charging it, and whatever other voodoo is recommended is a bad idea.

One charge for a day is enough for htc one if you don't play games

If you really want the most optimum battery life out of your phone then don't let it drain below 30% nor let it reach more than 90%. You'll likely get the most charge cycles and prolonged battery life with that. This suggestion sounds sarcastic but this is scientifically factual.

HTC One Battery Conditioning

G'day mate. When I had my HTC Desire, there was a process of conditioning that was advisable which pushed my battery life from 3/4 of a day to a full day. Having just received my HTC One last Friday (and what a magnificent phone it is too but that is a story for another day), I can honestly say that no conditioning is required (after-all, it does have a 2300mAH battery). I would suggest that you make sure that the first time you charge the phone, you leave it on charge for a minimum of 8hrs (as recommended by HTC). I left it on charge all day and I believe it does make a difference. As for making it last long, may I suggest you invest in an App called Juice Defender Ultimate (not very expensive but extremely useful) ? I am using this app and I have improved the battery life of my One from a single day to approx. 2.5 days. But I am an average user (emails, some internet, some music and blinkfeed). I don't watch movies on my phone so I am not too sure how that will affect battery life but I believe it will have some effect.
I hope this helps you with the answers you seek.

It's based on scientific facts.
When your battery has high load(Almost fully charged) more ions inside the battery are stored there hence doing alot of chemical changes in the battery. And chemical change is the only reason why our batteries here are losing it's capacity.
And the reason why I set 30% as the minimum is because you don't want your battery to be drained too much as there's likely chances that you'll completely drain it causing it to be broken also.
And why limit the examples on HTC One batteries? Is this a serious question or just a joke? We all know that HTC One was just released months ago and another obvious fact is it has a non removable battery. So obviously the answer would be none.
And about real life proofs about my usage and how it affects battery life do you want me to show you a nokia 3310 model still up and running for almost a 8 years now? Also want me to show you my nokia n900 which is already about 4 years now and still kicking it's battery perfectly up to now? I could have also showed you my n95 up and running till now if only it didn't break it's flex cable.
There's no such thing as integrated ticking time bomb on your battery(like rumors in the 20th century where they say electronic ICs have a hard coded date where they will totally shut off) where it would just instantly die once it reach it's recharge limit. What manufacturer in their right mind would do that? Smartphone business isn't a monopoly and every competitor would want the best of them all on their products. Also if this myth would have been true most people's device wouldn't even last a year due to plugging your phone on a computer would initiate a charge also. So would that mean that if I plug my phone on my PC 5x a day and charge it once a day it would only last roughly 6months? lol!
Also here's a good website that would backup my claim.

Did you read those websites? Because their numbers and yours don't agree. So either you made up the numbers or you obtained your scientific facts from elsewhere.

As much as I know....just dont overcharge and frequent charging. Overcharge meaning leaving your phone charged for long hours after it has reached 100%. Frequent charging meaning leaving your home with 100%, reach office at 85% and charge. Going for lunch with 92% and came back with 87% and you charge again. Get the picture? I'm no genius on batteries and dont bother looking up and reading on them. Just based on experience, over many phones. And yes, the first charge is very important.

I thinks the powersave is the best route when not playing any games. If you play games then you can call it quits!

I left it on charge all day and I believe it does make a difference. As for making it last long, may I suggest you invest in an App called Juice Defender Ultimate (not very expensive but extremely useful) ? I am using this app and I have improved the battery life of my One from a single day to approx. 2.5 days. But I am an average user (emails, some internet, some music and blinkfeed). I don't watch movies on my phone so I am not too sure how that will affect battery life but I believe it will have some effect.
I hope this helps you with the answers you seek.

As much as I know....just dont overcharge and frequent charging. Overcharge meaning leaving your phone charged for long hours after it has reached 100%. Frequent charging meaning leaving your home with 100%, reach office at 85% and charge. Going for lunch with 92% and came back with 87% and you charge again. Get the picture? I'm no genius on batteries and dont bother looking up and reading on them. Just based on experience, over many phones. And yes, the first charge is very important.

Given that the phone comes with charge in it, how much can you do to affect the first charge?

As much as I know, dont drain the battery too much the first time you take it out the box. All batteries comes with a little charge in it. Had a friend who used to work at a mobile company and I cant remember the term he used to describe that. But the first charge doesnt have to be exactly 8hrs. Phone might be fully charged after 4-6hrs if you hadnt used it much from the box. Just dont unplug it before it reaches 100% on the first charge. Let it get to full and leave it for another 10-15mins and its good to go.

Once at month, you have to discarghe the phone at 0%, put it in charge and switch on it when the led is green.
The battery life, during the day, depens of you and your use of phone

I let a cell phone battery get down to zero once. It never worked again.
I did the same with my house cleaning robot. I had to replace the battery after that.....I'm just saying.

Does keeping the charger plugged in after 100% damage the battery?

Sorry is this has already been asked before, I did search around.
I just got my HTC One a few days ago, and after coming from a Galaxy Nexus, I think that this is a extremely good phone. Obviously I'm very careful with it and don't want to damage it, but I'm worried that the way I'm charging my device is decreasing (or will decrease) my batteries life span.
I keep it plugged in all night because I obviously I don't want to charge it during the day. So does keeping the phone plugged in all night damage the battery or does it just stop charging all together once it reaches 100%?

It doesn't damage anything. I charge my phone the same way you do and my battery lasts as long as it did the first day i got it.

There is no problem keeping the phone on charge even if it reached 100% The only advice regarding battery that I can give you is: try not letting the phone discharge to 0%. Some ppl here had issues reviving their phones after a full discharge.
