I usually let my fascinate plugged in whenever I'm in my house. I keep my laptop battery away from being overcharged, but should I be aware of overcharging my phone too?
I know it discharges when it reaches a full charge, but it's still charging since it does receive current right? I don't want to shorten the battery capacity due to overcharging..

Your battery will stop accepting the charge when it reaches 100%, then trickle drain down to about 95%, then accept charge until back at 100%, then trickle down again and continue this cycle until you unplug. Everything I read about the Li ion batteries said even though there is this function built into the battery to prevent overcharging, you should not leave the phone on a charger for an extended period of time once it has been charged fully.
on the other hand... how long does it take to significantly shorten your battery life doing that?

$15 for a new OEM battery? If it gives you peace of mind, I'd just charge it whenever it's convenient.

I'm sure this link will work with the Evo 3D...what do you guys think? I'm trying it out tonight
Thats not battery calibration, thats bump charging, as it was designed to prevent the battery from being fully charged. Bump charging bypassed that feature.
From what I understand so far about the EVO 3D's charging method, this wouldn't work, as it stops charging when it reaches 100%, then allows it to discharge to 95% before it allows the battery to receive a charge again. I'm not sure what it would do to turn your phone off at 100% though. Of course, many people don't want to leave their phone off just to keep the charge level at 100%. Its also possible that you can bump charge it up beyond the actual 'read' 100% charge.
Also, from what I know about the charging characteristics of Lithium batteries, bump charging will shorten the life of your battery, which is why they made these phones to charge via these methods.
Getting my replacement today and my current phone has suffered from bad battery, so what is the best way to charge the new one please?
Thanks
I charge mine overnight most nights, and it gets better over time. It took a couple of weeks before I started to get really good life out of it.
Based on what I've read, you should charge for at least 3hrs and then drain it completely.
But I'm pretty sure you can still use it right out of the box
I don't think any extra/time specific charging is needed for Lithium batteries for the first charge. Just unplug it when charging completes. But if you calibrate the battery make sure you fully drain it before recharging it.
Regards.
It doesn't matter, there is no need to bother about how to charge modern li-io batteries.
I don't think modern batteries need any kind of special first charge routine....................but I still do it anyway

Just read about this earlier on my local samsung officially site and yes ever since it is lithium battery its ok to charge anytime afor how long even it already 100% and still on the charging mode ots automatically cut off the power supply inside. But i do still charge like 4-6hours for the 1st time

Just charge it to full, and then start using it, charging it overnight does nothing, the BMS will stop it from charging when the voltage coming from the battery is considered 100%.
Lithium batteries do not suffer memory effect like Nickel batteries.
The old charging practices cause more damage.
Lithium batteries should not be overcharged (Same as NiMh)
Lithium batteries prefer to be fully charged. If they stay on empty too long, they get damaged. Using the charge up before charging the battery can damage it, the optimal is to charge it before it gets low. Regardless how well you keep them, they have a predetermined life span, so they will stop working after a few years.
Thanks everyone I am going to charge it for about 6 hours, then calibrate then fully discharge and fully charge, Until o2 unlock it :'(

Completely pointless....once it reaches 100% it stops charging.
Someone pointed out the same thing you all said i.e.modern li-ion batteries don't have a memory, they don't need to be formatted, however extreme conditions aren't healthy for them e.g. leave it completely depleted or completely charged for prolonged periods of time (days?).
i just charge mine to full the 1st time i get it while it is off and i am fitting screen protector etc
i then use it till its about 10% and charge to full
i then use it as normal and top up charge whenever
it may not be needed but batterys have always been good for me and its a little routine i seem to be stuck in lol
hope your new phone is decent and you enjoy
Is it better to charge them separately?
From what I heard, the dock charges the Tablet. So if I charged with the two connected, the dock would charge, and it would in turn charge the Tablet...sounds kind of inefficient to me, and maybe even bad?
I usually charge my TF101 tablet from it's dock and have done so since September, perfectly fine and no negative impact on the battery. Just don't make a habbit of burning the batteries too low, like 1% before you charge.
My dock does drain a little faster after having gone through a bunch of heavy discharges but that's why I usually charge before I get to like 3% .

That's odd since it is recommended that you run the batteries down before charging them instead of putting it on the charger before it gets below 10%. Charging them without running the power down has a negative effect on the amount of charge it can hold.
That is not required anymore.The ideal charge level for these batteries is about 40%.
Charge cycles aren't a problem either so discharge is required once a month or even more.
These devices use LiPo and Co batteries.
For these, it is recommended NOT to fully let the battery discharge (unlike older batteries with memory effect).
It is however recommended to fully charge then fully discharge your battery ONCE when you first use it on order to calibrate the battery (ie: let the software learn what level means full and what level means empty)

You can check the link in my Sig. there is some info on recent batteries and calibration.
Yup, running it till it shuts off is mainly to calibrate the battery gauge. Most Lion batteries have auto shutoffs built into them to prevent discharging past the point of no return (which is why ebay batteries are so cheap, usually they lack this and other features, like temp sensors to kill the device before it melts)
As to charging both devices, i dont see how charging each together would harm anything aside from running more power through the dock might eventually wear it out? Honestly i dont think you have anything to worry about XD
But I can see the dock being discharged to zero so often. So far it has happened 4 times without me even knowing it since its often connected to the tablet. I wish there was a way to use the dock and disable the charging to the tablet.
Its better to have a few full discharge n full charge cycle for any new battery operated product to maximize the new battery capacity after a few cycles it will reach its peak capacity.

But I'm sure on many occasions just by the usage and nature of the dock that it will end up being drained to 0% quite often. I don't think my dock battery will survive too long -.-
Does leaving your Galaxy Note plugged in after it has reached 100% charged harm the battery?
From what I heard and read numerous times, you shouldn't leave a phone on a charger for more than 24 hours. I have heard many different opinions on this, but I think leaving a phone to charge overnight (6-10 hours average???) on a consistent base shouldn't harm the battery in general.
Is there "memory"?

Only in nickel cadmium batteries
I thought with Li-ion batteries its the number of total charges before it starts going bad?

Yep. Same with all batteries.
Hard to say how many charge cycles the OEM batteries are rated for.
From Samsung sdi...
No Memory Effect
Lithium ion batteries have no memory effect, as seen in Ni-Cd and Ni-MH batteries, from which repeated charging and discharging reduces charging capacity to an insufficient level.
Long Life Cycle
Lithium ion batteries last through more than 500 repeated charges and discharges, making them very economical.
also from other readings...
I am pretty sure that Lithium-ion batteries for smartphones cannot be overcharged because the device's circuitry stops charging the moment it reaches 100% and allows it to drop a certain % till it recharges. That's why sometimes your phone's battery % will reduce so quickly after a full charge because it is really not at 100% when you unplug it.
Manufacturers, however, will still recommend disconnecting after a full charge.
Another...
it is not good to allow your Lithiumo-ion battery to fully drain then recharge repeatedly, as many suggest, to "train" your phone...that's puts a stress on the battery and is not good.
A low % (15-20%) then recharging to full one time will reset the meter and make it more accurate but not lengthen the batteries life.
all that said...I plug mine in at night and unplug in the morning.
This link talks about the Samsung battery and charging. It sounds educated on the issue but who knows....

Summary
1. Use wall charger not computer
2. Unplug when charged
3. Don't recharge until battery is below 10%
I put the phone on my desk dock every night whether it needs it or not. I do find myself topping it off too much also.
So I heard that the reason why when you unplug your phone it immediately goes down to 98 or 97% is because the phones are designed to charge as fast as possible. Is there a way to program the phone to slow charge? (like overnight) so that it will get longer/better battery performance?
I am not sure where you heard that.
The reason that you unplug it and it is at 97% is because once the phone charges the battery to 100%, it slows down on the voltage. It lets the battery drain a bit, to about 95% and then trickle charges up to about 99%. It does this cycle until you take it off of the charger. So, you may unplug it at anywhere from ~ 95%-99%.
Well, wolf is probably correct, but I believe it is the charging circuitry in the phone and battery that regulates the charging rate. The charger voltage output will be the same at all times.
What I would like to know is how the charging system works and what aspects can be modified by the kernel.

You can make it charger faster in the kernel, but not too much.

The actual reason is that it's "bouncing" the charge in the background, and due to the way the OS set up to report, you don't see it happening. Li-ion batteries are happiest when they are either charging or discharging. The fastest way to wear one out is to hold it at a single charge for a period of time. To combat that, the kernel lets it get to full charge, and then switches off charging so the phone is operating off of battery for a bit. After it discharges a bit, it switches charging back on and tops it back off. That way, you have a full, or at least a nearly full charge when you unplug, and the battery is kept in a constant state of charge or discharge so it doesn't wear out as fast. The OS plays a little psychology with the user. Most users are going to expect that the battery should be fully charged when they unplug it, so once it hits 100% the first time, it no longer displays the actual percentage...it just keeps displaying 100%. After it's unplugged, it rapidly (over the course of a few minutes) scales down to the actual number before it's starts showing the real number. That makes people think it's starting at 100%, and it lets the battery longevity be maximized.
There are certain battery monitor apps that let you actually see the bouncing effect. The one build into Android Tuner is one.
Thanks for the info everyone!
