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.

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

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!
Hi i dont know why my battery isnt completely charging! or the battery charger info is broken! anyone else not charging to 100%?
It probably hits 100% then starts draining slightly to keep it from over charging. Mine gets to 99% then I unplug and replug it and it hits 100. But that has happened with a lot of devices for me.
Happens on my evo as well. You can get around it by flashing a kernel that does trickle charging which I'm sure we'll get for the tf sooner or later.

I would NOT use an sbc kernal on this battery, they are known to shorten battery life. Cell phone batteries are a dime a dozen, this thing is both non-user replacable and most likely not cheap.
Pretty sure its a lithium ion battery inside and you shouldnt overcharge those. You're best off keeping it between 30-90% and doing a drain and full charge once a month to prolong its life. The charger should stop charging when the battery is full on it's own anyways if you do leave it plugged in. I think it's a European law to have that as a safety feature, probably an American law for this too. So if the charger is staying hot a few minutes after your device has hit 100% charge, you've got a problem. Mine does get to 100% but yes it takes a while to top up, that's just the way these batteries operate.
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.

Do i let the phone shut off from the battery reaching 0%, then charge it to 100% and be on my merry way?
I've read multiple theories, but I think u should take it down out of the box, then shut off and charge to full...I remember ASUS recommending that to a media outlet when the Transformer 300 came out a few weeks ago...so that is what I am going to do when I get mine.
Thats exactly what I did, I let mine completely die and then charged to 100%.
Be careful with how you charge the phone, rather with how low you let it get.
Depending on how technical you want to get about it purposefully letting a battery drop to absolute zero can cause some odd chemical reactions that while not immediately evident can some times shorten battery life.
I would recommend taking it out of the box and using it until it is low but not dead. Maybe 10 or so percent and then either turn it off and charge it or leave it on and charge it just do not pull the plug on the charger until it is at 100%.

This.
Full battery cycles are not good for long term life of Li ion batteries.
Also, its unlikely, but occasionally happens where discharging the battery to shutoff will render the battery unable to take a charge. The safety circuit on the battery is supposed to prevent this, but its not failsafe. I've seen more than a few reports on previous HTC devices where this happened. And since the battery on the One X is not easily replaced, the result can be disastrous.
The battery meters on phones are not very accurate in the best of circumstances. No need to drain to shutoff, 10 or 20% is fine. No value added to draining to shutoff, and the consequences can be very bad.
Drain to 10% or even 20%, charge to full, repeat 2-3 times. This is done just to calibrate the battery meter on the phone. Its a misconception that you can somehow increase battery life by "conditioning" the battery. But modern Li ion batteries do not suffer from memory effects, and conditioning only works for older tech NiCad batteries.
I do the same thing for all of my phones.
1. Activate and mess the heck out of it until it dies completely.
2. Charge it up to 100%
3. Mess the heck out of it again until it dies completely.
4. Charge it up to 100%
5. Mess the heck out of it again until it dies completely.
6. Charge it up to 100%
Then use it normally

How do you tell if the phone is charged to 100% while off?
While on, my battery percentage doesn't seem to go past 99%. Is that correct or is this last 1% just taking a very long time?
Update: NVM last 1% just took forever. LED does turn green when fully charged.

The LED will turn green once it's 100%.
Don't worry about letting the phone die and charging it up to 100%.

Mine came dead too. Charged it to 100% and now been using it and so far have 36% on 3h 9m on battery.
Screen at 84%
Does the battery life get better? Because it seems to be draining rather quick. Even though I have screen brightness less than half.

@Maroon Mushroom, Correct these lithium batteries dont have memory effect, but over discharging them will shorten its life.
I dont want to sound like an expert, but discharging the battery until it dies is not recommended. It will affect battery life/performance.
A couple of good references here: http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries

http://batteryuniversity.com/learn/article/how_to_charge_when_to_charge_table
Ya, we use Lithium Ion (Li-Ion) batteries now which dont have a memory. The older Lithium Polymer (Li-Pol) batteries did have a memory and needed a certain charge method to get the longes life cycle out of it.
Awesome, thanks everyone
I turned it off at 20% and wen't to go buy my MicroSIM (ugh...) cant wait to play with it tomorrow

Hmm, i hate the idea of letting it die completely. But what i've always done is turned everything on and ran it through a low-powered usb source so it has a charge but the battery is still draining. So even if the battery runs dead it has power via USB plug [make sense?]. Usually having everything on [i do mean everything] and downloading a torrent so the internet is constantly under use. Then again i'm not sure how the One X will work out for this, but thats what i'm planning .
guys its lithium...u cant drain it to 0...even when android shuts down your at around 3.6volts. thats definetly not 0volts. no memory and android wont let you ruin your battery...so charge however whenever.

I wouldnt. Doubt it would but would but i find it pointless. It charges pretty quick and wouldnt want to leave it charging for 5+hrs The battery is superb i would quick charge a few mins before bed. Ive gone to bed with 19% and had 17% when i woke the next morning.

technically with Lith Ion the less you let it die all the way the better it is for the battery.

It's not going to outright destroy the battery, but definitely better not to keep it on the charger. I cannot speak to your schedule and work environment. I charge mine mid day at work. If your usage is generally the same on a daily basis, just find a spot where you can squeeze in a charge or two during the day.
Always changed overnight for ever I can Remeber. Never faced any issues.

i leave the phone on the wireless charger. it better for the battery or is the same?
let me clear it..
1st of all in modern battry charging technology overnight charging doesnt harm battery at all as lith ion batt never get overcharged..bcoz once its 100%(max threshold) charging stop and phone use batt powr
after that once it get around 100% ( lower threshold) it start charging again...
STILL I PERSONAL ADVICE TO CHARGE OVERNIGHT WITH FASTCHARGING MODE OFF(((OFFF)).

As far as I know, technically wireless chargers are worse for the battery than a wired. They produce more heat, which technically will have a larger impact on the battery. That being said, I doubt there is any appreciable difference.

Good point. Does ths fan cooler on the wireless one prevent as much heat?
The battery retains 95% battery life after a year of normal charging, I wouldn't worry about depreciation. Relax and enjoy the phone
No, you can charge your android overnight as they are smart enough
Boooom! Lol.....just kidding I hope
Stick with the samsung fast charger. I have a lot of other ones, and only the samsung stay cool (fan) and doesn't cycle like the cheap ones do.
Yes, as most have said, you can charge overnight. I have done this every single night for years, on all my flagship devices. Smartphone batteries have technology in them to stop charging when they hit 200% and only trickle charge them. It won't do any damage or won't cause long term battery life issues.
Just turn off fast charge if you're going to charge overnight.

I've also heard the opposite, as wireless chargers charge slower they put less pressure on the battery which helps it not degrade as fast. How much difference it would make either way I dont know, possibly hardly any.
I do know keeping it between 40-80 is widely regarded as being a lot better for li-ion battery degradation than going to 100% all the time or running it really low. Accubattery for example will say you used about 0.2 battery cycles going from 35% to 80%, but 0.92 battery cycles going from 55% to maximum. They are probably just using that 40-80 rule to work it out, but assuming it is correct, you can see how much effect it has, being nearly 5x more battery cycles despite both being around a 50% charge up.
So charging it overnight will get it to maximum, which isn't great in terms of battery cycles. I have seen a couple of battery apps that I think can manage charging so that it notifies you at 80% to unplug it, but I don't think they can actually stop the charge at 80% if you leave it plugged in (althought I might be wrong on that). Again how much real difference it will make I don't really know, and it probably depends how long you plan on keeping the phone, 1 year then it shouldn't be too much of an issue, 2 years or more and I would probably at least try to keep it between 40-80% when possible.
Ha,
Been charging all my phones overnight.
Been using wireless charging since the note 3 and always please it on the charger when im next to it and not using my phone.
Never had a battery problem
Thanks everyone for their answers ..*let the overnight charging begin*
I used Ampere to check how much current was going to my phone when it was fully charged and it read 0.0 so I believe the phone cuts off the charging function when fully charged. As even on 100% without the "fully charged" portion on, it will still show trickling voltage.
Hope this helps. I also advise turning fast charging off at night just to be safe.
