[Q] First-time battery charge

Do i have to charge till the battery is full, or do i have to keep it charging if its done?
I heard this a very long time ago, that if you charge the phone for the first time more then when it says: "Charged", you'll expand your battery capacity..

AFAIK the system stops charging automatically once the battery is full anyway...

Well, how much did it took for you to charge your phone the first time, its now over 2 hours charging and it is almost 100% ..
And does it say anything if it finishes?

I charged until the ring around the center button stopped flashing. It takes around 3 hours the first time.
I have no scientific proof but I don't think the first charge has any effect on the battery life, because batteries come precharged anyway.

Heh, I'll tell you people a story.
Back in the old days, batteries were made of "NiCd", and this chemical connection had the so-called memory-effect. The memory effect made it so that you had to fully uncharge and then charge batteries, so that it knew it's limits and the chemicals could adapt to that.
Nowadays, batteries are made of Lithium-Ion or even the polymer version of those. The memory effect is long gone, and basically, as long as you don't leave it depleted for long periods, nothing should effect the usability of the battery. Even better, Li-Ion batteries actually start losing capacity at the moment they roll out of the factory. It's a well know phenomenom with laptops and portable computers - this battery drain.
So, the answer is: no. Mobile Phones, MP3 players, portable devices and anything recharagable nowadays does not care about being charged, discharged or used the first time.

shouldnt make a blind bit of difference with a lithium battery, the old nickel batteries used to need 'priming' on the first charge to ensure a good life but things have changed since then
HTH

beat me to it lol

Well, just got back from shopping couple hours ago, and every single one of the store employees told me to charge the Diamond from 8 to 10 hours. And yes, it is 2008 !! go figure

'store employees' are the very first people I would ignore.

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] 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.

Short answer: No, but not recommended.
Long answer:
All good quality phones have anti-overcharge circuitry within. So, in theory, there would be no bad effect.
However, the circuitry might be degraded, so there might be a (small) chance your battery will be overcharged.
In addition, the system might be working 'harder' knowing it's connected to AC Power, meaning higher heat generation. And heat is a battery's worst enemy.
So, even though occasional overnight charging is acceptable, one should avoid doing that. Instead, charge the battery every time you have the opportunity to. Since Li-ion battery has no 'memory effect', that is what one should do, actually.
(Of course, every now and then -- say, once a month -- you should charge the battery until full then let it drain until the phone shuts down automatically. This is to 'reset' the phone's battery watcher calibration).

Is the quick charge harmful?

Hi, I'm using my samsung phone with quick charger, however, I saw some people discuss that quick charge is harmful to the phone, is that true? anyone can confirm about this?

I can't say that quick charge is harmful however what is usually not a great thing to do is to stick the phone on the charger all the time when there's plenty of power left. Like charging it from 80% to 100% is just wearing on the battery life faster and causing it to use an extra cycle.. Think of it like this say the phones battery can ONLY be charged a total of 100 times and that's IT no more it's dead after the 100 charge.. if you stick it on the charger at 95% and charge to 100% well now you just lost a cycle and you only have 99 charges left.. Wouldn't it have been better to use the entire battery power until it shuts off and then charge it?! Doing it this way actually extends the batteries life and keeps it working a lot better than constantly doing small charges.

Ive always been taught that the faster u charge a battery the less charge it holds. And decreases the life span faster. That slower is always better on lifespan.
The added heat from quik charge also puts strain on device if being used at same time.
Just my opinion

Ive googled this and according to some psyhics, it doesnt matter how fast the electrons get to 3,000 mah. What really harms the battery is getting above 90% and below 10%. Everytime you get to 100% it counts as an cycle, and batterys have a limited life cycle. My orignal barttery went bad after 11 months...degraded from 3000 mah to 2,200. I manually replaced the battery myself

this is also true
i just personally dont think its good on them to quickly dump voltage to them either

Not sure it will harmful to the battery life span, but sometimes I charge my phone to 100% and continue, so this will also harmful to battery?

You can just not use your phone battery at all. Once lithuim ion batterys reach 100 thats it, they then drain from your electricty So by turning on your power case when uts at 100%, the phone drains from the case. Of course if your using like an 1amp charger, theb battery will drain if using while plugged in., because the screen is eating more energy than the 1 amp can provide

Batteries are cheap....replacing them isn't that difficult. I got 20 months from my original battery(always fast charged).
If I get the same from the replacement then it's all good.
Use the phone....that's why you bought it.

Yes, forcing a lithium battery above it's operating voltage, something like 4.7v with a 5v to over come is ok. But 9v!?!? That's degraded it's performance. In the great scheme of things does it really matter? Probably not, chances are you will get a new phone in a year or so anyways and thats about when the battery fails.

Oops

I don't want to change the battery, and for now, more and more phone come with battery non-removable, it's not a good choose to change battery.

Its only hard if u want to keep your glass back. I tore up and shattered mine and dont care because my phone is always in a case, so youll never see the back. Got the oem battery from ebay for around 10 dollars. Then its just a matter of taking out all the screws, connecting the really small connector, and screwing back tightly. Like you need put pressure on screen when putting back together because for example volume down button might not work if press 2 lightly

It's easy, use a heat gun and the simple tools. Took me 20 mins and I didn't break anything. Just bought the battery off eBay
