how to take good care of you batt

http://www.batteryuniversity.com/parttwo-34.htm
good read as it seems many still maltreat their li-ion
acording to old ni-cam myths

Also, make sure you read http://wiki.xda-developers.com/inde... revolutionary, comparative, numeric results!

I've always said this simple statement about LiIon: Charge early and often.
Do you need to plug the phone in every time you get off a call? No. Do you need to worry about it dropping below 80%? No. Just charge as often as is convenient. Sitting at a desk for a hour working on something? Charge. Driving for more than 15m? Charge.
I think if you obsess too much you might wind up with USB connector problems from all the cycles on the connector itself, but intelligent use of the above statement should get you the most out of your battery.

that would kill the battery life fast, yea u wont run out of battery soon but keep it up and ur battery is gonna die on u after talking for 1hr

er.......what?

i believe that you have to charge your battery all the way full then use all the power until it dies then you can charge it back again
but not sure

This is the exact opposite of what this article says.

conditioning the battery the first time you get a new phone also helps, alot of us just charge for a while them use it. all my phones i let them charge for a full 24 hours right after i get them

My battery only last 6 hours

Ugh, why don't people read the article BEFORE they comment?

Ehh, doesn't the charger uncharge when the battery is full? Like a safety thing?

Some articles say that one battery life cycle is used up everytime when a full charge is done. Other articles say that one battery life cycle is used each the battery is connected to the charger.
I have not seen one article that shows the truth with facts.

No offence but I always found this to be stupid reasoning.
What if you leave home with a quarter full battery and you get caught in the middle of a natural disaster (earthquake as an extreme example) and need to keep in contact with rescuers after being stuck in a building for 2 days?
Personally, I always charge my phone/laptop whenever convenient.

The only problem that your battery lasts only for 6 hours is due to too much charging...So when you will buy a new battery then make sure that only charge your battery when it will remain only 10%...And try to charge your battery with phone switched off..

Charge little and often, try to avoid deep discharge/charge cycles.
Back in the days of NiCd batteries there was the posibility of memory effect where if you didn't do a discharge/charge the battery wouldn't hold as much charge.
NiMH batteries do not suffer this, but discharge/charge cycles were required because when they started being used very few people had smart chargers so had to discharge to be able to time when to stop without overcharging, and also due to confused information pulled over from NiCds.
Top up charges are better for them too.
Lithium batteries also don't have memory effect, and are better off with top up charges.
Ask yourself this:
What would stress the battery more; running 1A through it for 10 minutes or 1 hour?
Also, as the battery discharges, its voltage drops so the current drain has to increase to compensate, discharging the battery even quicker (remember how capacity graphs drop off quickly?)
Say your phone needs 2W to run, with a 4v battery that's a drain of 500mA (P=VI)
When the battery has dropped to 3.5v then to produce 2W it takes approx 571mA.

batt problem
how to keep my batt good?

I've always just charged my phones overnight while I sleep. Never seen ill effects. If I don't make it home that night my phone still lasts through the next day.
It's not like that battery is irreplaceable. Go get a new one if your battery is nearing the end of it's life. By then you would have probably moved on to a new phone.

skimmed a few parts, but thanks for the read mate, learned tons.

as others allready mentioned, there are many different suggestions how to take care of the battery. I usualy reload the baterry only if the capacity is <= 5%, without unpluging it before it reaches 100%.

thanks for the info!

[Q] how to make the battery charge life longer

hi friends
i wanna ask a question about how i can make the battery charge life longer?
thanks

It depends what type... I know one where you'd almost have to drain it but not all the way then fully charge it would make the battery life longer than having its life cut short.....

Try this technique which I used on SE XPERIA X10:
Charged the phone to 100% and while still plugged to the charger remove the battery wait 5 seconds put the battery back unplug the phone switch it back on and plug back into the charger. Ur battery should now show 88% charge not 100%. will wipe the battery stats as well when I will fully charge to see if it makes a difference.

Need to fully discharge the battery at least once a month until the phone off .. then you load up to 100%, and doing what was said above, remove the battery, and turns the charge again for up to 100%

In spite of reading a bit one sees immediately

A simpler way is just to use Battery Calibration app, it can be found on the market.

Is it a bad thing to charge the battery at 50% still?

wow is what i am interested , the method above i have tried but no obvious difference. so the app is really that helpful ? have you ever tried it ? i don't want to install then uninstall.

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.

First off, I agree with Anumunir. Replace the battery. It's a used phone. The slow charging is an indicator that the battery is old and worn out. Good batteries are cheap (Search for Anker on Amazon or eBay and that's what you want)
However, the issue with the phone jumping to 100% is adding to your problems. That's kind of normal....but it can be minimized. The problem this creates is that the phone thinks it's at 100% so it shuts off the power circuit to the battery so it stops charging. But it's not at 100%. It's at like 70%. So after you unplug, it quickly starts dropping to what the actual charge is. So it looks like it's draining fast.
Here's how you minimize this...
Frist, get the new battery..because why not?
Second, drain the battery until the phone shuts off. Restart it, plug it in, and let it charge all the way. Don't reboot. Don't mess with it. Just let it charge. When it gets to 100%, keep letting it charge more for another hour.
Third, use the phone until it drains all the way down and shuts off again. Play videos or a graphically intensve game if you need to in order to burn the battery down. Don't reboot it until you use up the battery.
Fourt, plug it in and recharge it all the way back up again. Now it should be smoothed out a bit so you don't get those big battery jumps on reboot.
Don't bother with 'battery calibration' apps or wiping battery stats that someone will repond to you thread with. They don't do anything. It's an urban myth.

whats the best time to charge out tablet on what battery percent should we start to charge? below 50% or below 15%?

im charging tab when its needed, 15% and below
charging time with 0% till 100% is about 2h n 15-20 min

When I need it, or when I feel like,it, whichever comes first.
Maybe you should specify the purpose of your question. Battery longevity? On time optimization? etc. Those two are not compatible by the way.

I read somewhere that you get longer battery life recharging at around half charge so I put it on the charger around 40-60 if I can, and I have Battery Full Notification installed from the play store that gives a notification as soon as its 100% and I take it off the charger.

Yes its fine to use while you are charging.
Here's the thing, these batteries will last longer before they begin to deteriorate significantly if you only charge to about 80% capacity , not 100%. Samsung laptops even include an option to do this automatically to extend battery life. Charging to !00% is harder on the battery, but of course gives you longer run time.
Running on the charger help if you are doing things like watching videos where its on for long periods.
The batteries only have so many charge discharge cycles , typically about 500 cycles for this type of battery, after that they start to loose capacity. However most in the industry expect your device to be very outdated by the time the battery fails.
