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.

Okay, I will plug it in for the first time. But what about second, third times? Should I discharge it completely?

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.

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!

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.

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. :/
Under mango or one of the firmware updates which had been updated recently , u will see yr battery saver is fluctuating , at one time saying u have a 1 day, while another time it says u only 2 hours on a reasonably fuller charge.
there is a problem with HTC original batteries, rather i will say a safety regulation after recent incidents with battery safety
yr htc only charges up to 85% level even though the phone indicator shows 100%
when u unplug it from the charger, it immediately drains and stays at 80%.
THis is likely why the HTC phones have a shorter battery life, whether its android or windowsphone 7
this is not a defective battery, its made intentionally by HTC for 2 reasons 1) safety , 2)battery longevity ,the safety mechanism built in stops charging it to 100%, thus overcharging, overcharging means the battery is out thru stress which may pose a hazard. if a battery is fully charged to true 100 % , it poses a hazard if one of the pins in the phone connectors break. apparently this pin tells the charger or the phone not to charge anymore once reaching 100%. there is a possibility that if this pin breaks, the phone will overcharge and pose a safety hazard. So this is why HTC batteries dont charge to true 100% and this particular pin is tweaked to full charge to only 80%
wheareas, mugen batteries ect do not have this safety regulation or charging limit although they are safe to use, so they seem to last 20% more than stock HTC battery because they fully charge to 100%.
Mugen or other reputed aftermarket batteries are more likely to wear out sooner than stock batteries unless depending on the quality of the battery..
in order to get yr HTC battery to full charge it u need to bump charge it.bump charging is a technique to fully charged the battery closer to its real capacity
to bump charge
1) fully charge the battery from 20% to 100% , as indicated by the phone OS
2) turn off the charger, turn on again, u will notice the phone charges again even though its 100% full for 1/2 a minute. wait for it to fully charge
3) repeat the above step 2) for 10 times
4)use a timer plug to simplify the process. Set the timer plug to on/off every minute for 10 times. u need to get a digital timer for this purpose with mutiple timer settings

Interesting. I noticed this with my HTC Mozart; battery indiactor drops one bar (to 80-85%) as soon as I take it off charge. Always assumed it was a WP7 thing - like it was drawing a lot of current.
Where did you get this info from? Looks like I'll be ordering a new (non-HTC) battery asap!
If it's true i won't buy a plug timer but a new battery, not from HTC...at least i hope it's true caus my battery capacity sucks and that gives me hopes, enjoying my hd7 more than a half day without plugging it (when it's possible)...so nuff thanks for the tip.

Funny, I have always done this with every device (maybe not the x 10 repeat!). never knoew that was the reason though thanks!!
not only HTC, there are couple of other devices like samsung galaxy ect
now u know why they claim mugen and other aftermarket batteries last longer...
mugen 1500 mah battery with the same size as the stock 1230 mah batt>
thats bull..because a 1500 mah battery looks much bigger ... the samsung omnia 7 has a 1500 mah battery and its 30% larger than than the HD7 battery....

thats because the battery stops charging once it reaches 85%
u may have heard of the HTC bump charging technique. thats what this si all about , but u need to do it everyday, so get a timer plug and leave it to do its job overnight everyday
the best is to use a digital programmable timer plug .
Ok, had a google and looks like your post is only partially true:
http://phandroid.com/2010/12/25/you...is-lying-to-you-and-its-not-such-a-bad-thing/
Appears it's an issue with all smartphones, not just HTC! Also bump-charging will dramatically reduce battery life.
As someone in the comments says; why can't the phone just stop charging and switch to running wall power once battery gets to 100%, same as laptops? I assume this is what Apple do, as the iPhone doesn't suffer from the same issue.
Interesting because I have no problems with my battery doing that running Mango beta 7712 on my HTC 7 Pro.
The moment I take my battery off once it turns green, it stays at 100% for hours if there's absolutely no activity on it.
I think it's how far you guys are draining your batteries. Ever since I've gotten my phone, only twice did I push the battery lower than 15% charge; once on accident and another to recalibrate it. After that, I never pushed it lower than 15% and made sure to only recharge it after at least a good 20% of usage (days i feared i wouldn't be near a charger and needed full charge).
Granted, I'll add that it maybe be because I swap the battery out every other night with a spare, and if I do so I make sure there's between 50-58% charge left.
No bump charging either.

yes its better to maintain 20% charge .
If u noticed the iPhone batteries wear out faster.
About year or so.
Just to confirm I have used the timer plug technique twice the last 2 days .
This is what I have
30% charge
8 hours since last charge
Moderate usage.
Somehow those who claim to use momax or mugen batteries claim to have the same results above .

You should not let Li-ION batteries fully discharge, ever. It's good to keep it on a charger whenever you can, than keep it off a charger and let it fully discharge. That wears the battery out.
Also, there's no risk in overcharging the battery because almost all decent phones will stop charging when the battery is full. They know when to stop charging, just like they know when to alert you that the battery is fully-charged (via a notification and/or changing the LED Notification light color).
You actually can overcharge it by exposing a fully charged battery to higher temperatures - putting the phone in direct sunlight or setting it in a car holder in the way of hot air from the heater deflector while using Satnav, for example. In order to avoid these conditions, controllers do prevent batteries from 100% charge. That being said, I don't think there's a standard for marking battery capacity, and an honest manufacturer should put real effective battery assembly capacity accounting for those limitations, not the sum of capacities of included cells. Don't think they do it really.

It's actually still not good to leave li-ion batteries plugged in when they are fully charged and stopped charging. They will suffer from capacity loss that way as well. Not to mention any heat coming off the device.
Update: i did not bump charge today..
and the old symptom returned again.. draining fast
so what is the best thing to do?
is there any way of charging,dis charging ect to get the best battery life?
or should i just charg it to 100% and use it right away?
i did a charging squence with my nexus s. but duno about the Gn.
for me is to turn on the device and start working until the battery drops to 0-1%.
only then im charging it X2 then needed to go to 100%, you can make it Double if you want.
Well, this is going to be one of those threads where everyone has their own little way to care for a battery and others say their way is better, etc, etc the arguments breaking out which will result in people posting www.batteryuniversity.com in an effort to win said arguments.
Here's mine. On a brand new phone, I put the battery in, boot up, connect the charger, run it to 100%, disconnect charge, run battery all the way down, connect the charge, run to 100% and go about my life charging when I need to.
My two cents. Have no idea if it does any good, but my SGSII is going on 1 day 14 hrs on a single charge, so it must work somehow...

My way,
Turn on phone, charge it to 100%, leave it plugged for an extra 20 min, and start using it normally.
The only time I discharge a battery is after a couple of months. Because we never charge it to 100% and they start creating memory and charging less and less every time. The purpose of discharging it completely is to erase its memory. That's why when it is new, I see no point on discharging it completely. Batteries suffer every time they are completely discharged and if they are left 100% for a long period of time, thats why new batteries always come charged about 50%, to extend battery life since they may be stored for a long period of time. (ref. aviation school)
Just my 2 cents.

That hasn't been true since NiCd's in the 1980s.
Modern Lithium-Ion and Lithium-Polymer batteries have no "memory" and are actively damaged if allowed to discharge fully.

Generally because they don't know any better and they don't realise battery technology has moved on.
Because batteries "back in the days" were quite sensitive to memory. That's why we were all raised by the complete-discharge-mantra, which sticks with you forever. The next generation won't have this problem and will feel free to charge their phones when they want to. ;-)

Becouse android in itself keeps a battery log, it is from this log your device calculates the amount of battery you have left. To keep these values true (calibrated) you should do 2-3 cycles where you on purchase, discharge fully until device auto shut down, start it WITHOUT charge a couple of times and let it die to set the min value, charge up to 100%, use your device again till auto shut down... you dont have to worry about damaging your battery in this case since your device it programmed to shut down with good marginal of battery depletion. What you SHOULD NOT do is leave an empty battery uncharged for a long period of time.

Lithium batteries will be damaged if they are stored fully charged or fully discharged for extended periods of time. Thats why the battery is about half charged when its new. They have no memory effect, they just loose capacity.

Good point. While it's important not to fully discharge the battery too often, there is also the issue of calibrating the battery meter.

That's exactly what I do, had 14 hours of moderate use today and still had 45% left. More than happy with that. It seems to be getting better each day at the moment.

The whole "discharging the battery fully" thing doesn't really apply here - because nobody will ever fully discharge it. The Nexus uses a Lithium Ion cell - it's a single cell, with a nominal voltage of 3.6V. When fully charged, it peaks at 4.2V (at which point, the charging circuitry cuts off to avoid overcharging). However, when we "fully discharge" our phones, the cell only goes as low as 3.5V - and then the phone shuts off.
In reality, lithium cells can discharge to around 3.0V before any damage occurs. However, this would yield very little extra battery life. Stopping at 3.5V provides a wide safety margin (lithium cells are potentially dangerous if overcharged/discharged), whilst extending cell life.
In a nutshell - don't worry about running your phone down to 0% (unless you're putting it in storage, in which case leave it at about 60%). In fact, it's a good thing with a new phone, as cycling (charging and discharging a cell) helps to "wake" the cell up and reach it's max capacity more quickly.

i see some good ideas about charging and discharging.
but it is indeed a fact that 100% and 0%(real) isnt good for our new race of battery's.
but a few posts here already tell how and what.
and its not gonna be a thread of arguments and stuff,if we all keep it in our heads that we just want to share our tip's of how you think its the best way(and have some experience with it)
just to share some info. and not compete the info against each other.
i well know there are different ways. but its always nice to read what experience people have with it to make a choice for my own and any other wanting to know this.
and i posted here in the GN section,instead of the Android section because each phone handles battery different,and this narrows the options down to a single device :3
Just keep in mind it's not just about the battery itself it's about the software registering how much actual power the battery has at a certain time, so if the battery has in actuality 100% charge in it, and the software reads 80 then your phone will die out sooner. So charging and discharging is good because it calibrates the hardware with the software. Just remember to switch off the device then charge it so the software doesn't auto discharge when it thinks the battery reached 100%.
K i just skipped thru the posts, gonna throw in my input real quick.
Basically just run down the battery. Once it turns off, hold the power button to make sure all the juice is gone. Then charge it up to 100% and leave it there for a good hour. Now (root required) download https://market.android.com/details?...yLDEsImNvbS5uZW1hLmJhdHRlcnljYWxpYnJhdGlvbiJd and follow the instructions .. its not exactly necessary but a nice thing "just in case" .
thats my plan anyways.

Lithium batteries will be damaged if they are stored fully charged or fully discharged for extended periods of time. Thats why the battery is about half charged when its new. They have no memory effect, they just loose capacity.

Where does the loosed capacity go? Can it be caught?
And what do you think about charging with the phone being switched on? Is it better to have it switched off?

Won't make a difference.. Phones are designed to be left on anyway.
So, I bought another battery. Will this sort it?
Also, what's the usual procedure?
Should I charge the battery to full in the phone (turned off) then boot, set up, then charge again and reset battery stats?
The problem is that the battery control chip doesn't take into account that the battery ages.
Resetting battery stats or charging while turned off will only clear the stats you see in the settings menu. This guide will make your battery drain to 0% again: http://forum.xda-developers.com/showthread.php?t=1534892
I don't know what a new battery will do though.
I gathered that, but as the phone is going to a new user (my stepson) we got him a new battery anyway
I just wondered what the correct procedure is. I know you need to do a first charge with a new battery, as with a new phone, however, this phone obviously has a working ROM already on it.
So, the phone is charging now, switched off. Should I turn it on, use a little, then use the battery calibration app to delete the stats and then drain to 0%?

Well, that assumption is probably inherited from the NiHM batteries in the past, because it's not needed with Li-Ion batteries. In fact charging to 80% is better than charging to 100% and keeping it plugged in.
You can read more about it here and here.

Just charge it and use it for a full cycle. If it shuts down at 15%, you can try the battery calibration from the thread I mentioned above. If it doesn't, you're battery capacity is the same as the one the battery chip has calculated, which is good.
So, why does the first charge take so long?
This thing is still charging and it's been on the charger for 3 hours, whereas usually it'd be charged fully by now.
Been like that for every Li-Ion battery I've ever had (including my S3, took around 6 hours to charge, usually takes 3).
EDIT:
Just to clarify, I don't intend on leaving it past the green light. As soon as it says it's full I'll be taking it off charge and not trying ot overcharge it. But I still have the orange charging light after 3-4 hours.
To be honest, I don't know. Maybe it's a safety to prevent overcharging. Coincidentally, I've got exactly the same issue now. I asked about it in the calibration thread. I suppose it's normal, but I'm not sure about that.

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?

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.
