Hi All, I have question. Which one better to charge
1. Wait until Battery level reach 15% or less
2. Charge it every we want it, example battery status in 40% because we want to travelling, we charge it until 100%
3. Charge it every morning
4. Other Tips?

Hello
You should just plug it in when ever you have the chance m8.
Li-ion and lipo batteries does not suffer from the memory effect as nicd and nimh batteries did.
The li-ion and lipo batteries will most likely die if you do a full discharge, but no worries, when your phone tells you that it's out of power, it's not fully discharged.
Your phone has at built in protection, that shuts down the phone before it uses all the power on the battery.
(Have been working with batterie for many years, as I have been flying eletric model airplanes, with all types of batteries)
There are a huge number of threads on this!

Thanks you for this tips... now I have more knowledge about battery.
A little bit question again.
What should I do, when I charge my HTC Desire? Keep this gadget turn on or turn off this gadget and turn on again when the charging has completed?

Just keep it turned on m8.
leaving it on has a disadvantage
as soon as battery is full, it discharges. at a certain point it would charge again.
you lose unneccessary charging cycles for your battery. so charge over night with turned off handset.
Not true really. The life of Li-ion batteries is mainly rated in full charge/discharge cycles between what the manufacturer recommends as the limits. Fox max life this is often a maximum of 80%SOC and min of 20%. They ship them about 40% SOC as this is where they have longest shelf life. The phone manages these limits for you so you don't need to worry. The best thing to do is to keep it topped up but let it run down enough during the day, or it reduces battery life (think laptop that gets left plugged in Vs one that gets discharged a bit per day - leaving it plugged in kills the battery).
IMHO - Use it until your next at a charger be that at 70% or 7%.
JAmes.
This thread here might be a good reference for this topic.

1. I always try to charge it 10-15%
2. Sometimes i do charge it if the battery is 40% and im worried it might not last because i go somwhere, so charge it till full and unplug
3. Most of the time i charge it over night having the phone on.
Right now, end of day 2 and battery level is at 29%, probably due to 3g turned off as got connection failed error for couple days and cant connect :<
Put my new second battery to charge last night around 9pm - turned Desire off. The green light came after midnight, but I let the charger stay on. I disconnected the cable around 9am this morning - and the phone was on!!
It looks the phone turns on automatically when its fully charged(???!!!)
The charge was 94% with the green light on. Makes me doubt if the suggested (see other threads) initial charge needs to be 12hours. :/
Hello,
So I am going to get HTC One X next week. Though, I have one question. Should I charge it first time for a long period or can I turn it on in shop, just to check if everything is okay and etc. I just want to have the maximum battery life, possible. Thanks for your answers
And hey, maybe you have any other suggestions?
I would get it home and stick it on charge until at least the light turns great. A few people are suggesting leave it for at least another 20-30 mins after this too if you can. I definitely wouldn't turn it on in the store; and HTC also recommend to fully charge before use.

Oh, okay Thanks. Well, I am just so scared... I don't want to get a phone with bunch of bugs
You're fine to turn it on and give it a quick test. All Lithium Ion/Polymer batteries have a partial charge for shipping as leaving it completely flat for long periods of time will damage it. Don't run the battery down though.
You should still charge it fully before using it properly however. Once the phone is fully charged then you can unplug it and use it. You don't need to leave it "charging" for 12+ hours even if the phone thinks it is fully charged.

Its normally better for the battery to run down to a low level before re-charging if you keep topping the battery up when it gets to 50 - 60 you could end up damaging the battery.

That is with NiCad and NiMH batteries. Lithium Ion batteries don't have the memory effect and actually prefer partial discharge cycles.
If anything odd happens then you can recalibrate the battery monitoring data by discharging it fully then charging it. In general however, you shouldn't do this every cycle.
My second phone that arrived took around 3 hours 15 mins for its charge light to turn green; I unplugged it after 4 hours and I was actually happy with the battery life on that one. My third one arrived earlier and the green light came on after 1 hour and 25 mins.
Guess they started with different battery levels? I will leave it on charge for another hour or so as I'm going in a meeting anyway; therefore when I turn it on its initial charge will have been around 3 hours long.
I believe you can't over charge the battery anyway, so once the green light it on there is a chance its probably not taking in anymore power. If thats the case leaving it plugged in once the light has changed is just irrelevant?

Li ion batteries are protected from overcharging, as overcharge could actually cause it to overheat and catch fire or explode. Not sure if the protection is in the OS, hardware, or battery. But basically charging will stop when the battery is 100% and saturated, then when the battery dips below 100%, it will top it off again. Not sure about the One X (still waiting for the AT&T variant), but on other HTC phones, you will sometimes actually see the battery meter drop down from full to 99% when its on the charger, then read full again.
So leaving it on the charger doesn't hurt things much (although technically partial charges are better for the battery long term). Leaving the battery charging for longer ensures the "saturation" charge is applied, which may not happen if you quick charge to full, then disconnect.

You shouldn't purposely discharge Li ion batteries until the phone shuts off. In theory, protections in the OS and the battery's safety circuit are supposed to prevent over-discharge. But its not fail-safe, and I've seen reports of plenty of Android phones where the battery fails to take a charge after being discharged to shutdown. If this happens to you, the only way to bring the battery back to life is with a special battery meter with boost function (which most people do not have access to) or buy a new battery (which is of course a problem on the One X, due to the non-removable battery).
Its rare, but it does happen, and there is no real benefit to running the battery until the phones shuts down. The battery meter is not remotely accurate enough to justify purposely discharging below 10 or even 15%, just for sake of calibration. Charge to full, leave it a while (30 min), then use until 15% charge or so. Repeat a couple times to fully calibrate the battery meter.
To answer the original question, powering the phone on (when you first get it) for a short time is ok. Just go through the battery meter calibration as I described as soon as possible thereafter, and it should be fine.

Brilliant post redpoint73; appreciate you taking the time. Just got out of my meeting so my device has been on charge for around an extra hour since seeing the green light so I will be taking it off charge now to set it up etc... Total first time charge time will have been 2 hours 40 mins.
It's likely it will be down to 15%-20% before I put it on charge again tonight as will be syncing all the apps and data back on to the device as well as giving it a good bit of usage to check things out. Will no doubt then be on charge for around 7 hours through the night whilst turned off, and I will do this for the first 3/4 days (same as previous one). My last battery was good so hoping for the same again.

It is pretty poor design if your phone does kill itself if you hit 0% though as that isn't too unusual of an event for a phone. I've never seen any phone which did that but I agree it could happen.
When I get my new toy tomorrow, I plan on using it! As per what I've read, gonna use it down to 10% or so...then give 'er a full-up charge. Kind of curious what everyone elses' plans are for their first time 'round?

Is that the general consensus on how to break in the battery? First move to an android phone and learning all I can.
I have always charged it up when i get it first then all the way down...but we all know how it is when we get a new phone....can't put it down! So...i play a bit first..
Confirmed tomorrow delivery!

Congrats to everyone *finally* getting their beastie! I can't wait for mine...nor can I wait to PLAY with it! I did some researching on ye ole battery issue...there are a lot of different theories...so I decided to go with the "drain it out of the box, then charge" because this fits in with my extreme need to PLAY! I read it may be a good way to go to "break in" the battery, if you're of that school of thought. Some people say they do not need "broken in". Some say they need fully charged first...yada yada yada and so on & so forth. I do think the newer batteries are different than those of yesteryear in that they don't have a memory, etc, and some of the old schoolers are still stuck with that thinking. Maybe. I dunno. I'm far from any expert. (I just wanna PLAY!!! lol)
Anyone try out that Ready2Go thing thru AT&T? Kinda neat. I did it. We'll see. I just did my contacts though. The rest is taking the fun away of customizing a new toy!

A Google dev came out and said on XDA a while back (the heck if I'm going to try to find the post) that battery stats have basically no effect on anything anymore. All the same, I "grew up" on cell phones by draining them to 0, then plugging them in until 30 minutes after they show a full charge, so I've just kept doing it that way.
It seems to me that companies wouldn't send out a battery without testing it... Which would involve charging/discharging it. So I don't think there's any need to treat a battery any differently when it's fresh out of the box than you would after the "break-in" methods people have posted in here.

this is probably why I do it too.
You should not be using the same method on Lithium-Ion batteries that you do on Ni-cad... cause they ain't nicad
Just do a little research. They don't require any break-in. Not only that but it's suggested you charge often and not fully discharge if you can avoid it.
Just plug the phone in when you get it and charge it up. If you want to use it feel free, plugged in or not.
Some common tips taken from Gizmodo and Blackberry's sites:
• Do not let it run out completely all the time. Full discharge puts a lot of strain on the battery
• Do not keep a Li-ion battery fully charged all the time, either. If you don't use your battery it might suffer from capacity loss
• Keep your battery in cooler temperatures. Hot hot heat is not good for it
• If you're gonna store your battery, leave 40%-50% charge in and store it in a cool place (i.e. fridge).
1. When you get a new Blackberry, charge it fully to 100%. There is no 120% or 130%, so once it hits 100%, it is fully charged. This normally takes about 2-4 hours for a new device. There is nothing wrong with “over-charging” the battery, however there is no real need to do so. Sometimes, new Li-ion batteries will come fully charged out of the box.
2. There is no “break-in” or “conditioning” required for the Li-ion batteries. They do not need the old “fully discharge – fully charge” routine for the initial three charges as was recommended on older battery technologies.
3. If you are a brand new BlackBerry user, keep in mind that you are likely using (or playing with) your BlackBerry much more the first few days than in normal routine use. If you think you are having quick battery discharge issues, give yourself a week or so until your daily BlackBerry usage levels off to a perceived normal amount. Don't freak out after the first one or two days if your battery depletes itself halfway through the day--You're probably using the device at a higher than normal use.

This is exactly right. Lithium Ion batteries benefit from smaller and quicker charge/discharge cycles. Actually draining a Li-ion battery to 0% and letting the phone die can decrease the total battery capacity and causes unnecessary damage to the battery. You should never do a "deep-discharge" and full recharge on a Li-ion battery.
Just pull it out of the box and use it, charge it before it hits 0%, and you'll be alright.
Heres another trick
I have done this more than a few times. Does it make a difference? I cannot say with anything more than anecdotal evidence, but I have had noticeable success and the logic makes a certain degree of sense.
Running the battery fully down often is claimed to be detrimental, and I have no reason to doubt that. Doing so once in say, 25 cycles is probably not a bad idea, although it does not do much of anything to capacity. What it does is help calibrate the battery meter. Than I add the following technique to increase the discharge time (run time) of the device:
At whatever point you finally let the battery fully discharge, do this as well:
If you have power saving feature, turn it off to get the job done. When it actually shuts down from being fully discharged, plug in and charge fully with the phone OFF. When the battery reached 100% fully charged take out the plug, wait a minute, and put it back on the charger. It will charge for 5-10 minutes more. NOW remove the plug, boot the phone, and put the plug bag in again (more charging ensues) and repeat one additional time. THIS technique seems to "Stuff" more electrons into the phone (see how scientific my explanation is? Whether I am helping, hurting or having no effect on the batteries longevity i can't say, but I CAN say is that I absolutely see longer cycles for quite some time after doing this.YMMV of course.
Whatever you consider "training" the battery, make 100% sure that the first full charge is indeed that: a FULL charge. This is one point that most documentation agrees upon. Getting the full use of the battery requires a FULL and complete first charge. Since I have no method to trickle charge, I tend to use the device while initial charging completes - I feel like that draws out the process, though why this is better. I can't say.
If only there was a definitive guide. Yes there are points in common among experts (such as running lithium ion fully charged all the time, especially warm, is terrible for them, yet almost all laptop makers let this happen by default when you run it on the charger (there is software to cycle the batteries), and some companies are including versions of this type of utility. Bottom line? batteries are cheap enough, but it's not ABOUT the money - It's about the run time. Heck - if I can't get good run time for a 3100 mA Battery, with a 2 amp charger, I better hang it up!
put the battery in, don't turn on the phone, and charge overnight. I know I know, this is the most difficult part. after that do whatever you like.
You are supposed to run the battery down every now and then(like every few months) What this does is it re calibrates the battery, separate from the android battery stat.
The batteries are tested and filled and drained then charged half way before packaged. A half of a charge is best for storage.
If your batter is dead when you open the box, exchange it. A battery sitting dead is really really bad. I have purchased a psp and some other devices that had DOA batteries and they never hold a charge for very long.
Android is the best I've seen with overcharging. Meaning there is none. The Android OS controls charging and doesn't allow the battery to fry like laptops do when plugged in all the time. I wouldn't worry about it with any Android device. Laptops should not stay plugged in for more than a few hours after full.
Running the battery down to zero (which is really 1-3%) is not "bad" what it really does is use up your charge/discharge cycle. Batteries have a certain number of charge/discharge cycles (like 300 or so) and running from full to dead to full every day will run the battery out faster; rather than charging it at half way or topping it off often.
please read post 11 and ignore anyone else who says anything to the contrary. i race radio control cars, we use lipo batteries, the system has a voltage cut off in the car for a reason. if you run them down too low, the cell will die, and will not take a charge. if you let them sit too long with a low charge, they will die. end of story. they do not need to be fully cycled like the old nicad batteries.

I say don't worry about it. The battery is replaceable and doesn't cost much. Enjoy your new toy any way you like and put battery worries out of your head.
Hey guys I'm often a lurker on here and don't post a whole lot but came across this article and found it interesting. Thought I'd share... Also, I like to leave my HTC ONE plugged in on my desk stand at work with the "Daydream" clock function running (basically using my phone as a desk clock). Do you think leaving it plugged in charging all day running this clock is doing any damage to my battery? It of course fills up and charges to 100% pretty quickly because I never really let it get below 80%. Below is my charging habit...
1. Charges all night at my bedside
2. Take it off the charger in the morning while getting ready for work and my drive
3. Get to work, plug it in for 6-7 hours running Daydream
4. Take it off the charger and go home... (off the charger for about 4-5 hours in the evening)
5. Go to bed, plug it in, and start all over again...
Oh and here's the article :lol:

How To Take Care of Your Smartphone Battery the Right Way
Click to expand...
Click to collapse
Your smartphone is a minor miracle, a pocket-sized computer that can fulfill almost every whim. But none of its superpowers matter a bit if it runs out of juice. With removable batteries becoming more and more rare, you've got to take good care of the one you got. Fortunately, it's not to hard keep the lithium-ion powering your everything machine happy if you follow a few simple rules.
Obviously, the first rule for extending your battery life is not using up all your battery life playing candy crush and walking around with Wi-Fi and GPS enabled when you're not using either and really, really need your phone to last that extra hour. But aside from that, there are some basic rules for care and charging, and they're the simplest baseline for a healthy battery.
Top it off
You may vaguely recall hearing something about rechargeable batteries and the "memory effect." You know, that if you don't "teach" your rechargeable batteries their full potential by taking them from totally full to totally empty, they'll "forget" part of their capacity. Well forget all that. Right now. It's wrong.
To get the most out of a lithium-ion battery, you should try to keep it north of 50 percent as much as possible. For the most part going from all the way full to all the way empty won't help; in fact, it'll do a little damage if you do it too often. That said, it's smart to do one full discharge about once a month for "calibration," but don't do it all the time. Running the whole gamut on a regular basis won't make your battery explode or anything, but it will shorten its lifespan.
So if you're really particular about optimizing your battery's life, you should try to go from around 40 percent to around 80 percent in one go, and then back down whenever possible. A bunch of tiny charges isn't as bad as going from 100 down to zero all the time, but it's not optimal either.
Keep it cool
It's easy to worry about bad charging habits thanks to the training we've had from old rechargeable batteries, but lithium-ion batteries have a worse enemy: heat. Your smartphone's battery will degrade much much faster when it's hot, regardless of whether it's being used or just sitting around doing nothing.
At an average temperature of 32 degrees fahrenheit, a lithium-ion battery will lose six percent of its maximum capacity per year. At 77 degrees, that number jumps to 20 percent, and at 104 degrees it's a whopping 35. Sure, it's not exactly practical (or sane) to keep your phone in the fridge, but it's worth going out of your way to prevent long stays in hot cars and the like.
Avoid wireless charging
Wireless charging is can be incredibly convenient if your phone can do it, but it's not without its disadvantages. The inductive, wireless chargers out there today have this nasty habit of generating a fair bit of waste heat. And while wasted energy is just a bummer in general, that heat will also toast your battery in the process. That's no bueno. It's a little less convenient, but standard plug-in charging is going to keep your battery in better shape, especially if you're some place warm to begin with.
Never go to zero
Obviously, using your battery is going to make it degrade. But it's going to slowly die even if you just leave that iPad in the closet for a bit. There's a trick to minimizing that inevitable aging though: leave it a little bit of juice.
If you're going to be shelving any lithium-ion battery for a long time, try to leave it with at least 40 percent battery power to tide it over. Lithium-ion batteries don't hemmorage power at 30 percent a month like nickel-metal-hydride batteries do; they'll lose maybe five to ten percent of their charge each month.
And when lithium-ion batteries get too low—like, literally zero percent—they get seriously unstable, and dangerous to charge. To prevent explosion-type disasters if you do try to charge one, lithium-ion batteries have built-in self-destruct circuits that will disable (read: destroy) the battery for good, if it reaches rock bottom. And sure, that'll save you from a face full of battery-acid, but it'll also leave you short one battery.
Don't sweat it too much
It's easy to get protective of your battery, but it's also easy to get lazy. And that's fine, because as long as you're not a complete idiot, you'll be OK. Typically, a lithium-ion battery lasts for three to five years, and chances are you're going to want to swap out your gadgets sometime in that window anyway. The slight damage of a technically bad idea like leaving your phone plugged in all night every night, or using wireless charging, might be worth the convenience.
Still, it's pretty easy to keep your battery reasonably healthy just by avoiding particularly egregious torture like letting your phone discharge from full to zero every single day, or leaving it in a hot car all the time. And the next time you make it back home with power to spare, you'll thank yourself for it.

I dont agree that your battery dosent like being or performs worse at a 100%. Or that it harms the battery in any way. I keep my phone plugged in as much as possible durring the day, and all night long. But i only use the wall charger that came with the phone, or a smart car charger made for my phone. Because as the article says, these chargers are smart enough to stop charging for awile after the phone has reached 100% to prevent over charging/heating. Cheap wall and car chargers dont have this feature and continuously provide a charge to the phone. Also charging using a usb port on a pc or other device does not provide this overgharge protection.
My last phones battery lasted for almost 3 1/2 years before needing to be replaced. Heres what i do.
Keep it charging as much as possible only with a "smart" charger.
Never let the batter drain all the way down. If it gets to 10% and i cant charge it at the moment, i turn it off.
Never let your device get too hot. Dont leave it in hot cars or sitting in the sun, etc.
Never "bump charge". That is just a way to trick a smart charger into overcharging your battery.
Also over clocking/volting your phone puts more strain on your battery than it was intended to take. It makes its temperatures rise higher, and the charge to deplete in a more rapid fassion. Both of which are bad for your battery.
These are just my opinions of course, but it seems to work out good for me. I think 3 1/2 years is a pretty acceptable life span.
never let it die
I have always left my phone's plugged in constantly and never an issue. Once my phone hits 100% it stops charging and then is very cool to the touch from then on.I heard phone's now has a failsafe that will stop charging and start running the phone off the charger and not battery.

What's the best battery conservative rom?
Why do you think you should never fully drain it?
Every 30-40 days, you should fully drain your battery - until your phone automatically powers down - and then fully charge it - and allow it to stay on the charger for 30-40 minutes after it's 100%.

The battery management system in the phone does not allow the cells to go lower than the safe level. For Li-ion cells, that's somewhere around 2.7-3.0volts/cell.
If it did, there'd be not only a huge warranty liability, but also a safety one.

You can believe that if you want to but if you actually read that link you will understand. It puts a lot of strain on the cells to go that far down. There is a physical reaction inside your battery of growing and stretching created from the charge/discharge cycle. If you regularly drop the charge to nothing then it makes it harder for it to keep a charge over time. You're more than welcome to do your method of calibration but I'm a firm believer in keeping the battery healthy.

I didn't say regularly. I said every 30-40 days. I have a lot of experience with lithium cells - both manufacturing and selling.
Before getting the One, I regularly used my HiTec lithium charger on my thunderbolt battery to run a discharge cycle, and then balance/charge it slowly.
No one need be afraid of their phone getting below 10%. It isn't causing any damage.
Well i guess its all a matter of opinion. Me and my wifes first smart phones were the htc incredible. I would never let mine die and the battery lasted fir 3 1/2 years. My wife would let hers die once or twice a month, and it lasted for 14 months before it needed a new battery. Got on her about not letting it die after we replaced the battery, much to my surprise she listened, and the replacement lasted for another 2 1/2 years. Both of our batteries actually still work today just not used to much anymore.
I had the dinc2 and followed the same procedure he used and pretty much nuked a battery from doing that same procedure. In less than a year my battery was bad. To each their own but I still don't suggest running it all the way out.

even anker, who is is probably the biggest portable battery manufacturer recommends not letting their products get below 25% because it can reduce the lifespan of the pack. They state that keeping it between 25-75% is ideal.
Interesting article, thanks for sharing OP.
I also leave my phone plugged in while sitting at my desk and let it charge up. Typically I plug into my laptop via usb while at work, once fully charged it shows 'fully charged' and switches the led status light to green.
I try to never let it die either but have to travel for work and do get very low on occasion, once I get down to 10% I typically just shut to phone off to preserve power while I am flying and avoid turning it back on again til I can get it on a charger.
Battery Life
I'm new to this phone,so I'm not entirely sure how the battery life is ... but I heard a while ago that you get the best battery life out of phones when you only plug them in to charge when they are completely dead. I don't do it often enough to see a difference, but has anybody else done it?
You probably get a much more consistent charge while it is dead/powered off. The only problem there is does letting your phone die occasionally ruin your battery or not?

Did you not read the first message in this thread. wherein it says:
To get the most out of a lithium-ion battery, you should try to keep it north of 50 percent as much as possible.
and
Never go to zero.
Alright, alright - I was merely saying I'd heard a theory stating otherwise.

My laptop, which is a Lenovo, has 2 settings. Best battery health and best battery life. Best health keeps the battery charged to between 50-60 percent and then stops the charge. Best life goes up to 100.

I tether with my phone all day and I have to keep it connected because it drains the battery quick. Will it have any negative effects on the battery if I leave it connected even if its at 100%?

I do the same and haven't had any ill effects, phone stays on charge at work all day
I believe the charger (and most, if not all, smartphone chargers) intentionally cuts out when the battery is saturated to prevent overcharging. Then top off again once the battery level drops a bit. In fact, on some devices (when attached to charger and fully charged) you will actually see the battery level occasionally drop to 99 or 98% then back up to 100% again. Although I haven't noticed this on the M8 yet.
You can get into a discussion of mini-cycles and other ill effects from keeping the device plugged in all the time. But just anecdotally I do this all the time (just leave the phone on charger overnight most nights) and haven't noticed much (if any) ill effect on battery life after owning 5 HTC devices, plus 2 Samsung tablets; most of which were used 1- 2 years each with very little if any decline in battery life over the time they were used.
Actually leaving the battery at full capacity all the time (if I understood your post) is bad for the long term health of the battery.
You need to find an app that cuts your charger off at 70-80%. Most modern laptops have this functionality built in for people that leave it plugged in all the time.

Technically, I would agree. And "best practice" is to cycle often and avoid leaving the phone on the charger when fully charged. But often folks (myself included) will not always follow what is best, and its not always feasible. As I've mentioned, after owning a decent number of smartphone and tablet devices and using then for 1-2 years, I haven't noticed much or any decline in battery life for the time I was using them (despite often charging them overnight). I have no doubt there might be some slight decrease, and especially of one intends to use the device for more than 2 years. But I personally never do (too much of a gear junkie) and also don't sell/trade my old phones.
Your point is a fair one, as it best the OP to know all the facts, risks, etc. and make his own conclusion. The following link has some interesting technical discussion on charging Li ion: http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
I bought an ampere-meter that measures current from the charge to the device and I have awesome news.
Li poly batteries have a very strict charging procedure (voltage and current should change during the charge). The original HTC charge charges flawlessly.
Once the battery tops up to 100% current drops dramatically.
If I do some power demanding task, the current goes up again. This means that all power consumption is taken from the charger, leaving the battery in 100% all the time, without jittering between 99-100%
NOTE:
Yet. The designers of the Li Poly define it as an electrical spring. This means there is no deterioration in the battery life AS LONG AS YOU DON'T CHARGE THE BATTERY OVER 4 volts.
100% is 4.2 volts, meaning you'd stop charging at 85% to prolong battery life.
