got a new battery and..

and I don't remember where, but I read somewhere, some time ago, that when you get a new battery, you should fully charge, and fully discharge the battery a few times.. Is this a good idea? does it help the battery?
are there any tips, like doing a complete cycle every so often?
Also, well, I got this on Amazon so I'm hoping it really is brand new. The brand new batteries are supposed to be dead, not charged, right?

Lithium ion batteries are never shipped "dead", bad things can happen (read up on it). So when you buy a lithium ion battery it always has a charge on it. They also don't have a "memory" like older batteries do so just use it normally. When i got my Naztech battery it was fully charged!

Ouch.. So does that mean my battery isn't going to be as good as an OEM battery? It looks like it's a legit samsung battery, it has the same model #
Anyway I charged it up fully, then I had to send in my phone to Samsung, so I took it out. When it gets back I'll see how my battery life is.

Li-ion batteries aren't supposed to have a memory, however I read a lot of good articles that argue no batteries have memory. However that being said, I've had the best luck out of cycling batteries like that. We have 7 Samsung batteries for our Fascinates, and always just run them down and swap to the next battery. Whenever I get a new one I charge it up, then run it down a few times.
I always charge them, they do come partially charged, but usually not 100%.

Any battery "woes" of memory is all placebo affect much of the time. Unless the phone doesn't get a balanced charge it will have no memory. But I think these batteries are one cell so you don't have to worry about it.

If you have 7 batteries isn't it a pain swapping them back in to charge them?

you can get chargers, like just a wall charger that you can drop a battery or two in and it'll charge without the phone.

Lithium Ion battery?

People keep telling me that its always beneficial to completely discahrge my phone battery and then do a full charge with no interruptions.
But then there are people that tell me to NOT completely discharge it as that'll ruin the battery.
What do you guys think?

Well I believe that with lithium ion batteries, that you should NEVER let them run out of juice completely or you will damage them. Nickel-hydride or something batteries are the ones you should discharge completely to avoid the battery memory effect. So my conclusion is, do not discharge completely. Lithium ions are more flexible when it comes to charging. I personally run my battery down to like 10 percent then charge it. It makes me feel like my battery is preforming well

It is all about charge cycles. They have so many cycles, as in... Charging from dead to full. Now if you use your device down to say 60% and recharge then the next day do charge down to 40% and back up that is ONE charge cycle.
So the more you keep the device at 100% the better you are for longevity.

Wow and I've always been thinking that its a really good time to completely drain it. Going to stop that from now on.

The less percentage you have to charge is directly proportional to longevityof the battery.

You are absolutely right. Keep devices out of the sun and if you have a device you aren't going to use for a month or more streight you should keep it refrigerated but not frozen.

How to make your battery last longest?

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.

Do you drain your battery daily?

I've begun to get the impression that skyrocket users keep their phones unplugged all day even if a charger is available.
There are so many battery threads about how long it batteries are lasting.
I'm just wondering- aren't we supposed to keep the batteries as fully charged s practical s often as practical and only completely drain and recharge once a month or so?

I plug it in at night and unplug it in the morning. A benefit of priapism. But I digress. I charge the phone overnight no matter what the charge level is. Simple and effective.

Keeping your battery at 100% and/or on the charger as much as possible is a great way to ruin your battery.
When I was using my Rocket as my daily driver, I could get 30-36 hours out of a charge, so I wasn't draining it dry by leaving it unplugged all day. You'll find similar stories all over this forum, as the Skyrocket has some great ROMs that give it stellar battery life.

I usually keep it plugged at night unless I am using it to play to fall asleep

Similar to a mechanical device that wears out faster with heavy use, so also does the depth of discharge (DoD) determine the cycle count. The shorter the discharge (low DoD), the longer the battery will last. If at all possible, avoid full discharges and charge the battery more often between uses. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles to prolong life
Under normal circumstances this should not be necessary because once the lithium-ion battery is full the charger discontinues charge and only engages when the battery voltage drops. Most users do not remove the AC power and I like to believe that this practice is safe.
I dont know how reliable the source is:
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries

Battery life is one of my only complaints about the device. I don't know a ton of facts about batteries but I let it charge overnight and at most I can get about 7-8 hours of heavy use. If I don't charge my phone at school, it will be dead once I get home. I have used several different ROMs with varying battery lives. My brightness would always be on lowest, no live wallpapers, etc. CM10 got me about 5-6 heavy use. Slimbean got me about 4-5 heavy use. 4.1.2 deodexed touchwiz died in about two hours moderate use with only using to send a few texts and change phone settings. Now I've decided on Liquid Smooth
Which seems to get me 7-8 hours of heavy use. Of course these all weren't tested with the intention of finding the exact battery lives by using the same process on each phone, but I did get some knowledge of how different ROMs affect battery life. Now I'm waiting for AOSP 4.2 and I'll be trying that. I hope this helped.
Edit: Somehow misunderstood the subject of the thread. I don't intentionally drain mine daily and if it is at 100% then I take it off the charger until its about >70%

How to properly charge battery?

I read on a thread that this specific battery will lose a percentage of its capacity every time it's charged below 20% or above 80%, is this true? & if so or if not then what is the best way to charge the battery in this phone without deteriorating it?
Sent from my HTC6525LVW using XDA Premium 4 mobile app

Everyone has their own opinion on this. Draining it below 10-20% could shorten the overall lifespan but I doubt the 80% or higher part you read is true. I personally charge mine every couple days and I'll still have about 30-40% left. I don't usually let it go lower than that. Rechargeable batteries like to be charged and killing them can damage them. Like a car battery, if it runs dead several times, it will most likely be ruined much earlier than if it wasn't ran dead. Just keep above 20% to be safe. Everyone's opinion of lowest percent is different.
