I havent gotten a new phone since 09 Hero.....whats the deal with battery charging. Do I need to fully charge the phone before using it? Do you drain the battery fully before re-charging it?
what give the battery the best life possible?
Never, ever, never, ever, never, never, ever drain a lithium based battery to nothing. Very, very bad. Charge it and keep it above 50% for the firstweek.

Even your Hero should be the same. Most modern cell phones use Lithium Ion which do not have memory effect.
There is no memory for Li-ion batteries so go ahead and just use your phone. You do not have to keep it above or below a certain charge. The phone will not allow the battery to drain to completion so you do not have to worry about that. It is very bad to let a Li-ion battery completely drain but there are fail safe measures implemented in the phone/battery to prevent that. 0% charge on your phone does not mean 0% battery, its just the mA at which your phone thinks the battery has 0% battery remaining.
I wonder if there's going to be a similar procedure to the OG EVO's plug, unplug, turn off, charge, unplug, turn on, turn off, charge method (or whatever it was) to maximize battery life.

Bump charging works for lots of phones to my understanding. Something about how the phone at first doesn't charge to 100% - when it gets to a certain point it just keeps it maintained at that level .
While it is true that lithium ion batteries don’t suffer from “memory” problems such as NiCad batteries they do have a lifespan. For example, the lithium battery in the laptop that I am using right now, and have used for the past year, currently has a 98% charge and is not charging. That’s much, much better than a NiCad battery would be. I can really see the NiCad issue in my rechargeable cordless tools.
But lithium batteries will eventually die. Just ask the first generation iPud owners. Their batteries were failing just after a year of ownership and Apphole wouldn’t do anything about it. They had reached the end of life of their batteries.
Lithium batteries do take a little bit to break in though. You’ll notice a slight improvement as time goes on for the next month. But I would still refrain from draining the battery too much.
Thanks for the input...I too have the hero, and was curios...
...is it Friday yet?
there was a recent article I seen from a link in the g2x forums where they go to actual experts on the lithium who designed the actual cells and ask them how is best to charge them.
the honest answer is for life being your most concern. that means for the battery to keep a consistent charge over the life of the phone without losing actual daily life on the battery,
you have to plug it in when the phone ask at about 20%. then unplug it when the phone says the battery is full. Do not leave the battery plugged in for hours over full. said something about the charge disburst weird or something
anyway it was a link in the g2x forum in general. im sure you can finds it. Ill look if you really want me to,
Lots of info on Li-ion batteries:
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
Being that the Battery stats are stored on the /Data partition, how is this minimum threshold managed?
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
Okay, I want to see some ways you guys calibrate your new battery. I just bought an OEM battery, and I have read many ways of how people calibrate their batteries. I just want to know what you guys personally do, and is there any "official" way said to do it?
When I get the battery should I drain it all the way or charge it for 6 hours?
I have read a lot of times that charging it to 100 then draining to 0 five times gives optimal charge, but I have also read on that it doesn't help with lithium-ion batteries. Can anyone shed some light on the subject?
Also anyone got any links to good external battery chargers since I need one now that I'm going to carry two batteries.
I usually charge them up full overnight then run them into ground first few times.. This will become an endless debate though if that actually does help or not lol, i know with older batteries it used to but thing the new technology batteries it doesn't make much a difference. I still do though figure may as well I always have why stop now
I want to use 2 batteries for travelling where I need a lot of juice for GPS.
One battery will be recharged with the S2. The other battery with an Anker wall charger. That's just a plan right now
I would like to know something concerning the best recharging strategy & battery "calibration" if you are using more than one battery:
If you are using only one battery it's quite simple how to calibrate the system.
But if you are using 2 batteries alternating then you can run into trouble, because the system is "calibrated" to the first battery.
That means if you are using battery1 until 0%. The system knows battery empty. I you are putting the 2nd - already recharged with a external wall charger - into the S2 then I wouldthink that the system is confused, because you didn't recharged it internal.
I want to use 2 batteries for travelling where I need a lot of juice for GPS.
So I would use the first battery until 0% and then change to the 2nd which is already recharged and then draining it until 0% and then again recharging.
The other strategy would be drain the first battery until 0%, then using the 2nd until the evening and then recharging both during the night. But I think this strategy will confuse the system.
Hope you understand the problem and I hope someone knows the best solution!
Thank you for your help!

You don't need to calibrate the battery on the s2. The device should fix the percentage by itself. I would not recommend that you drain the battery fully to 0% as i have heard that it could damage the battery and use multiple cycles for the one you drain it. If you're running SiyahKernel you can try to reset the fuel chip in extweaks. Some say that it's a placebo but I seem to think that it works.
Hope that helps you out

You are over complicating this, just change the battery when it's flat and everything is ok.. I have 4 batteries, two Samsung and 2 off ebay, I always have one in the phone (obviously!), one charged in my pocket and one in the desktop charger.. Never have to worry about battery life
Sent from my GT-I9100 using XDA
The batteries should be charged just right if you use the wall charger, however sometimes when you charge in the phone, it might stop at 96% or somewhere around there, sometimes I off the phone and charge, gets it to 100%
You shouldn't worry about calibrating or whatever, new batteries with li-ion battery should be okay without calibration

sounds inconvenient. better get a big battery replacement along with the new back cover
Sorry for upping this thread, but so (as traslate meaning) can you alternate a 1650 mAh stock battery and a 2000 mAh original Samsung battery without the needing of a wipe/recalibration?
Yes.

i've heard that calibrating is just a myth or something.. i have to batteries and i just change them whenever. (idk if that's bad or not), i don't wanna complicate it or something lol
Calibrating is a myth. Charge to 100% and enjoy.
Yes, no problem if you are using the same batteries like original 1650mah, just change the battery when empty and recharge

Again, sorry to bring this thread back to life.. However I was wondering if anyone has had issues with using two batteries and having the "fuel gauge" chip fault on them. On my previous Galaxy S3 the chip that is dedicated to measuring battery stats, as found on many other phones, developed issues. This lead to the phone registering increases in battery percentage while off charger - basically the battery history graph at any given time had a 60% chance of going down and 40% of going up.
Could the use of two batteries caused the "fuel gauge" chip to malfunction?
Maybe temporarily. But charging it to full and/or resetting the fuel gauge running a kernel that supports same fixes that issue easily.

Perform shallow discharges.
Instead of discharging to 0% all the time, lithium-ion batteries do best when you discharge them for a little bit, then charge them for a little bit. The table below, from Battery University, shows that discharges to 50% are better for your battery's long-term life than, say, small discharges to 90% or large discharges to 0% (since the 50% discharges provide the best number of cycles-to-usage ratio).
Don't leave it fully charged.
Similarly, lithium-ion batteries don't need to be charged all the way to 100%. In fact, they'd prefer not to be—so the 40%-80% rule you heard is a good guideline. If you do charge it to 100%, don't leave it plugged in. This is something most of us do, but it's another thing that will degrade your battery's health.
Fully discharge it once a month.
This may seem contradictory, but hear us out. While lithium-ion batteries shouldn't be discharged regularly, most modern batteries are what's known as "smart batteries". This feature can get miscalibrated after a lot of shallow discharges. So, manufacturers recommend fully discharging your battery once a month to make sure this stays accurate.

Is this true?
you can be as neurotic as you like over this, but it really d doesn't make a lot of difference, just enjoy your phone.
Sent from an abused battery
The only big no no is to constantly discharge to below 5% and recharge . That according to the experts leads to a much shorter battery life .
Yes leaving on charge is a waste .
Wiping Battery stats does not improve battery life .
But all this is an old story posted time and again and bring nothing new .

It may be a waste but is it detrimental to the battery? I always plug my phone in when I go to bed and take it off the charger when I get up in the morning.

there is a built in feature that stops charging once battery level reaches 100%. so there will be no harm to your battery. I have doing the same since gs1
My old Nokia 3510 needed a battery replacement after 4-5 years since it only held 3 days worth of charge instead of the usual 7-8.
I constantly let it discharge from 100% (overnight charging) to empty, the replacement battery cost me 5 bucks.
My Galaxy S1's battery has, after 2 years, no observable loss in capacity with overnight charging to 100% and dropping to 10-15% over 1-2 days.
A replacement battery would cost roughly 15 bucks.
I could go on the same about my Laptop, Netbook, Tablet and other devices with rechargeable Li-Ion batteries.
The point is; don't try to forcefully extend your battery life, enjoy your phone. Most people replace the phone every 1-2 years and the batteries are designed to live that long with high usage and deep-discharging. If yours should not or you plan to keep the phone longer, a replacement battery is cheap.

All Lithium batteries have it (and need it) since there is a risk of damage, fire or even explosion when it is overcharged. That's why not the phone but the battery itself has the corresponding controller. Since the controller cannot measure the exact capacity of the battery (only an estimate), it is recomended to deep-discharge and fully charge (charge-cycle) the battery once in a while to reset the controller's counter.
Battery replacement is cheap and easy as abc. That's the benefit of having removable battery. Just enjoy your phone.
