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

hence the " go figure "
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.

[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.

Please do not follow this advice. This used to be the best way to stop NiCad batteried from developing low capacity 'crystal memory' but it is not the case with LiOn or LiPo batteries, in fact, quite the opposite. Doing as he recommends is much more likely to damage the battery and even start a fire.
A LiPo shouldn't be discharged by more than 80% if at all possible. If you want to know more there are a lot of links on the interweb but here's a typical thread on stack exchange .. and a quote from it ...
http://android.stackexchange.com/qu...-first-time-charging-on-li-ion-batteries-myth
Nowadays, batteries are often Lithium-Ion or Lithium-Polymer and such batteries (as I have read many times and based on my own experience) would be stronger if you charge them often. The first time charging and "wait-until-full-discharge-before-recharge" and "don't-use-when-charging" are not applicable to these modern batteries.
Li-Ion and Li-Polymer batteries, if charged often, after about 1 month, would reach to their maximum performance, and you are recommended to charge them every time you find an outlet!

Wow, now we have the Richard Dawkins of battery advice. Well done.
Can everybody just calm the funk down and charge their batteries as and when they see fit? It's fine. Either way.
There is circuitry inside the battery that will prevent them from over charging, under charging, over discharging catching fire and generally behaving badly. There is also no memory effect. Just charge them when you think you'll need them.
Yeah just keep using it, if one day in the distant or not-so-distant future it doesn't turn on for some reason and/or seems unresponsive, it might need charging.

Hmmm .. shows how out of date I can get ... I didn't realise that the overcharge protection had reached such a state of sophistication ... Personally I never bothered with battery regimes, even in the bad old NiCad days ...
Thanks for the correction.
The overcharging prevention was first introduced to the Sensation and EVO 3D phones. I remember when I started seeing it because I would leave for work, and sometimes my battery wasn't charged fully. What it was doing was charging to 100%, then stops charging and will let it discharge 5%, then start charging again. And it would keep doing it until I took it off the charger. I've yet to see my EVO 4G LTE do that, though. Maybe it's been refined so that we don't notice it as much?

On the note of over-discharging: just because there is circuitry inside the battery to prevent over-discharging doesn't mean you should ever let your phone run down to (what your battery shows as) 0%. Yes, the phone will generally shut off when the battery is left at around 3v, but it's still possible to force turn your phone on (which you should never do) after that point. Not to mention, leaving the battery at a low voltage for a significant period of time WILL affect the overall lifespan of the battery. Battery manufacturers will do what they can, but there is really no such thing as "true" over-discharge protection, as with overcharge protection, since batteries will still lose charge even when not in service.
Yes, if you let your battery run down to (what your phone shows) 0% occassionally, that is OK. But you should really only be doing that if and only if you need to re-calibrate for cell mismatches.
Hah! I still remember when I bought a mugen battery the instruction clearly says to discharge it fully and charge it fully for like 5 times to get optimum capacity Obviously I didn't do it. I am much aware of these things since good old Nokia 3310 days.
Is my charging routine bad? Here is my daily recharging
I let it charge over night. By the time I get home its normally in the 60% or so. So its left on all night until about 7am.
Then about half way through my day I charge it again while I'm at on my office. By then the phone is around 70%. So I let it charge to 100% then move on with my day.
So about 2 times a day I charge my phone. Is this healthy for the battery or does it not matter? I'm trying to get the most out of my battery. I seem to burn about 3-4% per hour with it just sitting on desk. Thanks for any advice!

Nothing wrong with that
You are charging twice a day though so you will half as many days until your battery dies. Still a couple of years until it reaches 80% capacity though

Well yeah, but don't worry about it. You'll get another phone by the time you notice a battery drop on this phone.
Ideally you should be charging the phone when the battery gets down to around 40% and charge it to almost full, 97%-99%

I've always felt that the less you charge s phone, the better in the end. And once its done charging, unplug it. So don't leave it charging over night. I have a timer set up so my phone charges only for a few hours a night then shuts off. When I wake up, my phone is usually in the 90%+ range

That's simply not true.
Lithium-Ion batteries are designed to be used - not to be used as permanent storage (thats why batteries in always-coorded laptops die faster)
(storing li-ion batteries should be done at 50% charge, never 100% nor 0%... )
Li-ion batteries should never get below 30% and likewise never hit 100% - The reason why, is because you are stressing the battery the most in the extreme ends... an almost empty cell is stressed when it has to deliver .. and an almost full cell has to charge at higher voltage to reach 100%.
So the best thing you could ever do is to charge from 30% to 95% if possible.
Regarding the amount of charges... with Li-ion you shouldn't think about the AMOUNT of charges, but the SUM OF HOURS that your charge..
so lets say you charge 500 times a year and you in total charge for 500x4 hours = 2000 hours of charging..
the battery usually last for 5.000-10.000 hours of charging ..
The reason why it is so, is because charging li-ion burns the Kathode (or Anode, can never remember) -- and when its all burned off, the battery wont charge anymore ...
Discharging too fast, also burns the Kathode (Anode) !!
Everyone is all over the place in this thread. The two things I will tell the OP to do is not leave the phone plugged in over night, and stay away from 100 and 0% and you will be fine.
But even if the OP keeps treating his battery the way he says, it will be okay. Not ideal, but still okay.
I personally try to keep the phone between 30-80%.

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

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.

It's difficult? Could i ask you which battery to buy and where you bought it?
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
