So I just got my galaxy s3. I haven't turned it on yet. But I heard that you were supposed to charge it fully and then let it die. Then charge it fully again and then start using it. That when. Doing this you will optimize your battery so it will charge faster, hold a charge faster, and just last longer.
Is this myth or fact? And if fact how do I do the steps so I get it right?
Thanks for the help and sorry for any mistakes it was typed on my phone that has aa small touchscreen.

Yeah running it fully out of battery like that harms the life of the lithium ion cell
Always?

Now is this ALWAYS the case?
To clarify what I am asking I am saying does it always harm the life of the lithium ion cell by letting die fully? Like even after 6 or 8 or 12 months of owing the phone (or any device), not just one the first charge. This could be very useful for further reference...:good:
There are some things can help increase life of litium batteries. First, don't let it go down to 0% as mentioned, keep not lower than 50%. Once per month it is recommended to discharge battery to 0% and then charge it to 100% again for device callibration.
This is a good question. I always thought that by discharging and charging batteries at full cycles, you would make their total useful life last longer.
In fact, this happened to me with a notebook, which I used to play with and charging at the same time. In the end, the battery lasted for a few minutes and I had to sell it.
But in all: is this really true? I would also like to know if is truth or myth.

Yes yes!!
This happened too (as funny as it is) my grandma. She would ALWAYS have her little nnotebook plugged in and eventually it drained. I found out because one day I took it off the plug a d it died while I was on facebook after around 7 minutes.
So I bought a new battery and now she charfes iit and takes it off the plug to use it and twice a month she lets it die and it has worked

1) don't keep live wallpapers
2) keep the brightness to the lowest possible
3) don't charge while playing games or even use the phone
4) don't use apps which run in the background and drain the batter
5) all the suggestions given in the above posts lol

Don't let it die to zero.
When it warns you at 15% just charge it.

Sir i just want to ask If we charge our battery even if its above 20% or if the battery icon is not yet colored red will it affect our battery life in the future? Or we should only charge our battery when it is below 20-15% ?

It is true if you have a phone like Nokia 3310 if you do not have a NiMH battery do not do that you will lose time also you do not need to "format" a Li-Ion battery
read about lazy-battery effect on Wikipedia
rooting you phone to underclock/undervolt should also help out battery life pretty significantly ^_^
Lithium ion cells do not suffer from the "memory" effect as older rechargeable batteries. You do not have to let the battery run all the way down then fully charge it again to get the best performance that way, that was for the older types of batteries (again so you wouldn't get that "memory" effect) matter of fact its rather harmful to the battery to run it all the way down.
Charge the battery as often as you want no matter at what level it is. If you are going to do some high power **** (play a game, watch a movie) then plug it if if you have a charger around. The longer the battery stays at a high level the better for it. Try not to let your battery run your phone at a low state (charge it asap). Its ok to leave it on the charger even after its fully charged. Your phone and charger are smart enough to know when to start/stop charging the battery. This will ensure a long life for your battery.
...as for your phone...simple rules...if you are not using it( DATA, WIFI, GPS, SYNC, BLUETOOTH) then turn it off. Screen is the biggest battery drainer...KEEP IT ON AUTO!...darker themes really help alot...make your screen go off at 30 sec. or less. Have fun with your new phone homie.

Ok guys, so recently I'm starting to use my smarthphone ( xperia ray ) to do lots of things and one of it is as my Agenda. Now the real problem is, every time my phone is running out of battery I must charged it ( obviously -.- )
And everytime I charged it I always shut it down because people say that it's better to shut i down so the battery will have a long life
Can you guys tell me how to take good care of a battery ? And is it true what I said ?
( Sorry for my english -.- ):fingers-crossed:
I don't really think that offline charging will have any impact on battery life.
Anyway, from my experience the best way to conserve your battery health is to charge it in full cycles. That means not to charge it when it's on 40% but let it drain to almost empty or empty and then let it charge until it's full.
Your battery life will become worse with time. That's how rechargeable batteries work. Every battery type (Ni-MH, Ni-Cd, Li-ion etc.) has a different amout of recharge it can take. It won't recharge fine 100000 times and then after the 100001st time "die". It's life gradually shortens.
That being said, if you haven't used a phone/battery for a long period of time, it is always wise to drain it totally and charge it full for 4-5 times and then you will notice an improvement in battery life.
Also lower your display brightness. Display is eating most battery power, especially if you're using your phone a lot

Never over charge,like after charing 100%also never plug in to current,as it bring downs the battery performance later.....
I have wasted my 2 mobiles battery in same way.
I even fear for battery bust!

Battery life is affected by temperature, so try not to let your phone stay at high temperatures for too long

You can't overcharge your battery, that's a myth. It charges to 100% and then it stops charging, even if it's still connected to a power source. It starts charging again when it drops to 95% (hence why you sometimes see "97% Not charging" on your phone).
And yes, in some cases temperature can affect battery life but usually only in short-term. Still, it's a good idea not to leave the phone in direct sun in the summer or in your car in the summer. Extremely cold temperatures can affect its life too. Most batteries actually have written on them what temperatures they can withstand.

Is it safe to charge the battery overnight?
I mean, charging more than 100%, charging over the 3-4 hours needed, charging for 7-8 hours..
I think it won't effect it cuz i charge my phone from overnight too.nothing happens.
when battery gets full it stops charging after that
Of course
I've been doing that for a year.
Usually my battery reaches 10% at the end of the day, then I just leave it charging over night.
Thanks, i've been doing it since I bought the phone but I've never really cared until now..
Do you guys turn off the phone before charging overnight?
No. I don't know how does it affect the quality/capacity of battery though!
I remember as a kid I had those RC-cars and there were always warnings about how it will 'destroy' the battery if it is charged for too long. lol.
I don't have any battery problems.
Just make sure your LED isn't turned on!
I once forgot it on overnight...
It's a little dimmer now. :c
They said once it reachs 100% to stop charging. It can have an negative impact on your battery. Lithium technology or not. But I do it too. I think it just shorten the life span on a slow scale.

Here is the thing...
Yes the phone has a voltage shut off when it reached 100%.
However, it will start to drain battery immediately once it cuts off charging. Even when idle with teh screen off it uses some power. And once it drops to 99% it will start charging again until it reached 100%.
Depending on your set up and how much the phone runs when idle it would keep 'topping off' the battery several times overnight. This is harsh on the battery.
So it's not like once it cuts off charging it stays off until it's unplugged and replugged in. It'll keep charging everytime it drops to 99%

Here is the full question: Does modern smartphones protect the battery making energy bypass baterry when it is full charged? (like most laptops do)
This is related to: is it bad to keep my phone plugged to the wall charged for 15 hours? is it true that doing this makes the baterry go 100%-99%-100% and it "drains" battery's life taking cycles?
Is this the same for all devices? I have a Samsung Galaxy S Advance (i9070)
Thanks!
EDIT: MODS, feel free to delete, i couldn't because there is not such option! I posted this in the wrong sections.
thanks.
The charging circuit lowers the charge to a trickle, to keep battery charged.
I find I can get an hour or two more phone time if I keep charging after it says 100%.
If every thing is working right you shouldn't damage the phone or battery.

Subscribed to this thread as I am very interested in the answer myself.
It is float charging at that point. Battery levels are determined by the battery's voltage. A fully charged lithium ion battery sits at about 4.2 volts while a nearly drained one would sit at about 3.3 volts. This is how your phone knows when to stop charging the battery. So when it gets to the highest point, it stops and lets it trickle out a bit. Then when a little bit of energy has bled off, the charging circuitry kicks back on until it reaches the threshold again. Then the process repeats. It does this to maintain a healthy battery level without overcharging. Hope this helped

Thanks for the information. Its very informative. :good:
Will constantly charging a phone result in reduced battery life?
Constantly charging a phone will not affect battery life because it's just float charging. Float charging keeps batteries charged but not too charged, drained but not too drained. Of course lithium ion batteries will just eventually wear out because they're good for about 300-400 full charge and discharge cycles. But that's FULL charging and discharging. If it's float charging, the battery will stay good for years.

I have gone through about 3 cycles if battery, with fast charging turned on. Battery life has not been good, especially with screen off drain. Getting about 3hrs SOT while I've heard people say theu get around 6.
So my question is how many cycles should I go through before I judge battery? And should I disable fast charging? Does fast charging damage the battery?
I have the verizon US variant, so there isn't much I can do to improve battery life without root...
Thanks
Turn fast charge off. Turn off AOD. I have an AT&T model. Helped my battery immensely....
I can go the entire day, 6am to 11pm, with average usage and have about 40% battery left. VR drains my battery like butter on a stove.

I'm also on VZW and I've had my S7 for a week. After about 3 days of poor battery life (~2hrs SOT), I turned AOD, location, BT, and NFC off, and disabled a bunch of bloatware (I posted what I did in the battery thread). That improved my SOT to over 4 hours +more standby time. I've since re-enabled BT and location and haven't noticed a difference. I left fast charge on but I use a slow charger at night, just because that's what's plugged up behind my bed.
Sorry, I don't have a source but I'm pretty sure I read something credible that said fast charging doesn't affect battery life/quality. I know that's pretty flaky, so take if with a grain of salt because plenty of other people are saying it helps.

I too have some similar questions just like @gleggie has posted
"how many cycles should I go through before I judge battery? And should I disable fast charging? Does fast charging damage the battery?"
Also how to measure battery cycles? Any credible app for the same?
Fast charge doesn't affect battery life immediately, charging your phone faster causes heating and overworking of battery, so slowly, average battery life decreases.
Slow charge when possible! (Wireless charge generally heats more than wall charge!)
... My 2 cents
My phone on fast charging, even wireless doesn't get any hotter than previous phones. My other half has a HTC One M8 for two years and still gets 5-6 hours SOT and has fast charged since day one.
I use fast wireless charging and get 6 hours SOT.
All I turned off is NFC, and my signal is usually full.

So, to slow charge a S7, do we have to turn off fast charging from the settings and then charge via the charger that came with the phone(the so called fast charger) or should we use a charger from an old phone say SIII etc.?
Does this hold true for Motorola's phone also which have turbo charging option?
Also how to measure battery cycles? Any credible app for the same?
Just turning off fast charge you do a lot good for your mobile..
One thing you can do is check battery temperature as you change charger or method. I don't know about Motorola, but maybe its battery is user replaceable... I personally don't know any app that keeps track of battery temperature

Thanks for replying. I wasn't able to find any battery cycle file/log in that location, quite strange. And yes I have the Exynos version. I will test your app and will get back to you.
Of the little what I have understood from various threads here is to charge the battery when it is between 20-40% to 80-90% if you want to have a good battery life. I used to do the complete opposite charge, when the battery is at say 6-7% and charge it till it is maxed. I used to do the same for my laptop, any other tip for the battery?
