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.

[Q] Charging the battery

hi!
i have a question regarding charing the battery. let's say the xperia z has something like 63% battery left. and i put it on the dock and let it charge up to 100% (or even less, e.g. 90%). and i do this quite often, will it some kind of "damage" or harm the battery, so that the battery life will decrease?
i mean the battery life doesn't seem to be that good, so i plan when coming home to put it on the dock, whether the battery is empty or not. and then when not used, leaving the phone on the doc.
thanks for your help & have a nice day

That was the case with old-style Nickel-Cadmium batteries, but no phone has used those in a long time. With modern Lithium-based batteries, regularly charging shouldn't be an issue.

It will lose power after time - all batteries do. You can charge it as long and as often as you want, it doesn't matter. If the battery loses its capacity - remember that Sony covered it under 24 months warranty and you'll get it replaced it its maximum capacity falls down under ~75% of its original capacity.

There are free apps on the market that can assess your battery capacity. Of course if you're going to claim warranty - Sony will check it with more accurate methods, but even those free apps can measue your batterys's health quite accurately.
I'm not sure about the 75% number. Might be lower, might be higher. Usually it's set at 80% but i'd have to check that in the warranty itself ( will update the number when i get home )

[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!

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.

Question How do you charge your phone when you first buy it? S21 Ultra 5G?

How are we supposed to charge the phone? Do I let it drain all the way to zero the first few times, to "calibrate it" and then try to keep it between 80 and 30 percent?
I've heard getting to go all the way to zero is really bad? It also causes the battery to heat up a lot when it's being recharged?
I've gone through one charge cycle so far. And charged it at 11%. I wanted to let it go to 1%, but chose not to.
Someone help me with this. What is the best way to treat the battery when you first get it?

I just charge it when it goes low and I have time to plug it in. I don't have a specific preferences, whether @ 30, 20 or 15% regardless. I don't think there are any special requirements for that, though I see ppl create their own beliefs and the'd swear to it as "the most optimal charging routine".

Thanks man!

Any other opinions would be greatly appreciated.

At this point in battery tech i believe it doesn't matter. But a lot of ppl and articles suggest to keep phone in 20-80% range.

I did charge it up to 100% when new, then let it get down to about 25%, but generally I try to keep my phones as close to 50 as possible, with shorter frequent charges. I have wireless chargers on my desk at work and home, so it's simple to just set them there occasionally as needed. I have fast wireless charging turned off to keep heat down, and an app on the phone with an alarm that goes off when the charge hits 75%, but I'll often take it off closer to 60 if it's convenient. I'll put it back on around 40%. I'll charge it up further if I'm going to be out for a long day, and will plug it in if I need a faster charge. https://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries

i use accubattery and use its alarm function to alarm me by default 80% charged

or better to not have a smart phone at all if people get so picky!!
Guys, just do as the phone tells you, when it reaches 15% .. put it on charger until 100%. It gonna last at least 1-1,5 year before you notice the degradation of the battery.

Using the same method as @nightoooo above.
I'm only on my 2nd phone, first was $99.00 phone that lasted 3 years and now over 2 years into my Samsung A20 with no noticeable change in battery life.

I use the AccuBattery app with IFTTT and a smart plug for the charger. I set AccuBattery to create a notification when battery charge reaches 76%. This creates a notification saying to disconnect the charger once a 76% charge is reached. The Android device service in the IFTTT app sees this notification and then IFTTT sends an order to the smart plug’s app telling it to turn off the smart plug. I have been using this configyration for several years and it works like a charm. My previous phone, a Pixel 2 XL, has never been charged to 100% and after 2 1/2 years of use the battery is still working fine.

My 10+ lasted 1.5 years of heavy usage.
It then failed. Don't delude yourself as to the longevity of Li's. You may do better or worse.
Batteries are cheap and relatively easy to replace. A Li failure can total the phone.
Regardless how long it last once it's capacity is less than 80% of it new capacity it's time to replace it.
Degraded Li's are more likely to fail.
Signs of failure; sharp drop in capacity in a short amount of time, erratic fast charging, case bulging ie battery swelling which can damage the display or worse.
There's no reason to discharge below 20% except to calibrate. Charging beyond 90% takes too long and is stressful on the battery.
Li's prefer frequent midrange power cycling. This isn't a NicCad or a lead acid so forget those rules. 40-70% is near ideal.
Charging start temp should be 82°F or above.
NEVER attempt to charge one that is 40°F or less.
Avoid letting charge temperature go much over 100°F.
Regardless of the charger or time, it will stop charging at 100%... if you insist.
I use midrange power cyvling with a fast charger because it's quick and convenient, more bang for the buck. If I replace this battery next month I really don't care as at this point it's just routine maintenance to me.

Here we go again. No, they're not easy to replace for the average Joe.

Don't make me laugh too hard... I was once like you. Have someone do it for you. I got mine done for $50 and learned.
There's not many phones that are harder than the 10+ to replace the battery.
And it's a cake walk
Replacing the LCD screens on my 5D and MK3 were harder only because you need to line up the one time use wrap around rubber skin perfectly the first time when reassembling.
Still intimidated?

It's difficult to buy genuine batteries in many countries. Most people would rather have an original battery from the manufacturer last longer than have it degrade and replace it with something from a questionable source. Again, the discussion here is how to minimise battery degradation and prolong it's life rather than learn how to replace a battery.
Analogy: If someone asks a question like "How should I drive my car so that the engine doesn't wear out fast and lasts longer?" To suggest that you should not cultivate good driving habits, and abuse the engine, then replace it in a year isn't going to help. This kind of approach may work for someone who like to drift and drag-race or race but not for the average person who likes to take good care of his/her stuff.
Everyone knows that when something fails and stops working, it needs to be replaced. But that isn't what we are discussing here. We'd like to prolong it's life and prevent premature failure.

About a month ago I went on the Samsung Members app and put in a request that they add the ability to terminate charging at a user selectable charge level in their Bixby Routines. I then called their tech support 800 number provided in the Samsung Members app and verbally made the same request. The person I spoke with thought it was a great idea. I have never heard back from Samsung about them implementing such a feature though. It would possibly help if they received many more similar requests. If it was a popular request they would be more likely to add it the their software.

The worst thing you can do is not change out a degraded Li. You risk destroying the whole phone. Excuses are like...
You want to ration your cell usage?
Go for it.
I could add a whole list of things to prolong the battery life but it's not worth it.
The battery is flimsy, cost about $14 and was born to die. Parts are readily available especially a year after the release.
Even an amateur can change one out in less then an hour. Rear covers are about $16 but you won't break it if you don't rush it. But the details matter and you can't force parts or over torque screws, less is better. If you're really nervous practice on some scrape phones which aren't too hard to come by.
It's a lot easier than rotating a set of tires or changing a set of spark plugs.
Right off the top of my head, what you need:
Heat gun, fine tip tweezers (for the micro connectors), the proper micro drivers* (sold in kits just for this), plastic picks, sunction cup (optional), anhydrous isopropyl alcohol with a needle applicator syringe or bottle, OEM adhesive seal for the rear cover and the battery. About $35-50:less the heat gun. Optical aids are optional. Keep room humidity greater than 50%.
Sounds intimidating but it's not. Learn by doing.
*use a magnet to magnetize them if they're not already.

How are we supposed to charge the phone? Do I let it drain all the way to zero the first few times, to "calibrate it" and then try to keep it between 80 and 30 percent?
I've heard getting to go all the way to zero is really bad? It also causes the battery to heat up a lot when it's being recharged?
I've gone through one charge cycle so far. And charged it at 11%. I wanted to let it go to 1%, but chose not to.
Someone help me with tKodi noxhis. What is the best way to treat the battery when you first get it?

I simply charge it when it goes low and i have time to plug it in. I don't have a particular preferences, whether or not @ 30, 20 or 15% regardless. I don't assume there are any unique necessities for that, though I see ppl create their own beliefs and the'd swear to it as "the most optimal charging recurring".

When I first get the phone, I charge it to 100% and that's it.
After that, keep it in the 30-80% range and your future self will thank you.

Is there a way to verify battery capacity to verify battery replacement?

With the announcement of the 1-year extended warranty, I went to go replace my battery today at ubreakifix. When I picked it up, the employee gave me the feeling they didn't actually work on my phone but billed Google for the work. Besides the fact that the things he said made me feel like they didn't actually work on it, I noticed when I picked it up the battery was within a few % of when I dropped it off. I'm trying to see if there's a way to check capacity or anything of that sort I can do to verify that my battery was or was not actually replaced.
I appreciate any help.

Your SOT should noticably longer.
New batteries typically have around a 50% charge on them.

It was around 47% when I picked it up but I dropped it off at 53% which I thought was odd. That's good to know the range is correct for a new battery though. The guy was sketchy and made several comments that made me think he didn't actually touch it. I was hoping to check capacity or something to verify the change but I'll use it tomorrow and see how the battery life compares. If I'm still having battery issues, I just wanted to have concrete proof if I went back. He made a point to say "if it's still acting up then you'll just have to call Google and have the device replaced instead".

I've seen a lot of bad techs. You could always take it to a 3rd party repair if it turns out the battery is still defective.
Maybe he's just shifty acting in appearance only.

Yeah hopefully he was just awkward or something lol. I'll see how it plays out the next few days. Hopefully he replaced it. I plan on buying the Pixel 6 Pro but it would be nice for this to hold off until that comes out.

You can use AccuBattery to check estimated battery capacity. You'll have to go through a few charge cycles to get an accurate estimation.

I might give that a try as well. I heard that just estimates but I guess that's better than not having any idea at all. I'm doing the first full charge since I got it so I'll download AccuBattery and run it the next couple days. Thanks for the suggestion.

It's total battery capacity estimates are not accurate. If you had been using it before it's SOT/% history would be useful.
I use it track my battery usage % vs SOT to spot misbehavior.
It's charging time/% history is also useful for monitoring charging. Erratic fast charging is one of the signs of a battery failure.

It's history is but the actual mAh measurement isn't.
With no calibrated reference of the voltage to mAh ratio it can only do so much. I believe it's measuring voltage drop and calculating current and mAh from that instead of voltage×current.
Whatever the reason(s) it's absolute battery capacity isn't accurate.
I maybe mistaken but even though some power controller chips have current sensing capabilities, Android doesn't use that readout or make it available to any apks.
An Android shortcoming.
A Developer here maybe could or has shed light on this before.
Edit: some brands/models can apparently:

No information on Samsung models that I could easily find.

Like I said, I have found it accurate enough in my experience. New phone is around 100% estimated capacity. Year later, 90% or so. Year later 85% or so. Done this with several phones.
Not here to debate or argue about it. If the OP doesn't want to use it, they don't have to.

That 10% is from the original OEM battery and the replacement. Android it's self lists it at 4100 when it should be 4300 new. Accubattery uses the Android figure unless you change that value.
He'll get a good enough idea if the phone last longer during usage. It should be a noticable improvement... and I hope it is.

The battery capacity for this phone is 3,700. Like I said, I'm not here to argue or debate it. You do what you want and the OP will do what they want. So please stop quoting me. Let it go...

Just reporting back that it was definitely changed. I charged it before bed and decided not to put it in the charger over night to see what happened. I woke up and it was still at 99%.
It's been off the charger since 11pm yesterday, it's 8pm now and I still have 16%.

Another way to check is with this online tool https://bathist.ef.lc/ Battery Historian. Make sure to charge your phone to full keep on the charger for a bit longer even after 100% If you can do it with the phone powered off that's even better. Turn the device back on take a bug report and upload it to the site. Then look for the "Coulomb charge" value and mouse over it. It will show you how much the device charged in Mah say for example you see 3650 then you divide it by the battery capacity for our device which is 3700. This means your battery health/capacity would be about 98.6%.

Assuming that phone has accurate current sensing hardware and it's readout is available. All Androids report voltage relatively accurately... current not as much so.
