2 problem is the battery does not last me a full day and i got nothing on it i need a bigger battery asap or i got to return the phone my mytouch lasted longer than thins one please some one help me find a way to get it to last longer or a bigger battery thanks
I am wishing for an extended battery too. Currently, I'm using one of those Duracell pocket lithium ion USB batteries.
http://www.microcenter.com/single_product_results.phtml?product_id=0321688
Having another device and cable to carry around works, but is a pain...
my battery easily lasts a day. I can get through a full 9 hour day of work and still have 78% battery left. Not to mention I left my phone off the charger last night, got up 10 hours later and the battery only went down 3%
You sure you dont have any programs open? Also I don't use a task manager if that means anything to u

I bought this, it took about 2 weeks to get to me,(but for 12.99 for 2 batteries and a wall charger) as it was coming from hongkong, but got it yesterday, and its great, 2 extra batteries, and a wall charger so now i dont even need to charge my phone, i let the battery die so i can train them right, and just pop in a fully charged one when needed. the charger even has a usb hookup like the original wall charger that came with it, so really you could charge an extra battery, plus the one in the phone through the usb cable. The batteries are the same as the stock one that came with the phone. I wish i would have done this with my G1, instead of spending 90 bucks on 1 extra battery that didnt even have an external charger.

That would work, but I use the phone most of the day. It is not idle.
I take my phone off the charger at 5am @ 100%
Text most of the day at work with a 30 minute phone call at lunch...
Some moderate browsing and gaming...
I get home around 530pm, and "usually" have around 40%...

They are Samsung batteries, they look exactly like the one that came with my phone( down to the details written on the battery, only different thing is the date which was from 6/10 where the one with my phone was 7/10 and the s/n number), so I would say yes it is the same quality.

i bought the same set of batteries and charger. i'm still going through the charging/cycling phases with these new batteries. i'm not sure if they are on par with the stock batteries but i'll soon find out after a few more charges.
I am still doing that also, but I have to say that the wall charger is worth the money so even if the batteries don't work out, at least I have this awesome dual wall charger!

haha yeah i was about to say the same thing. charges pretty fast and has a cool blue and red-pink colored charger indicator
so far. the batteries are not on par with the stock battery. i work eight hours shifts. my battery runs down to 35-40 pct with moderate usage i.e. facebook, youtube, casual browsing by the time i leave work.
these ebay batteries drain all the way down to 5 pct by the time i leave work and on the eigth hour. i'm on my third charge cycle. hopefully i'll see some improvement this week.
here's what i have running in the background on my phone at work the whole day:

I got the same type of deal on ebay, 2 batteries & the charger (did the same thing with my MT3G as well), it's always nice having extra batteries, and I can use the charger when I'm traveling (it will also charge up my PSP). Now just need to get a mini to micro USB adapter and I have one less cable to carry around for charging - although I recently got an external drive for data storage, so I guess I will need a second cable if I want to tether my phone and use the external drive.
The batteries are not as good as stock and one seems to hold a charge better than the other (have to mark them so I remember which is which - these are generic one without the Samsung label), but as I train them via charge, use until dead, swap, charge, this should at least max them out a bit. The ones I had for my MT3G actually outperformed the original battery that came with so was hoping for the same. But considering how cheap these are, I could even pick up a couple more.

Those batteries from Hong Kong are not an original Samsung battery, they are just compatibles.
The lasting power of a li-on battery depends not just on the mAh, also the circuit inside the battery counts much of it.
The circuit takes care of the special sleep modes and energy saving features of a battery.
Samsung has its own energy saving codes that can not be put into a common compatible batteries.
This is why an original one is much more expensive than a compatible ones.
Extended battery for the vibrant, lasts twice as long and great door
Check this out: Moretalktime's feedback is 100% and the door is soft rubberized--better than stock IMO. It cradles well in your hand in a very comfortable position and lasts over twice as long.

Re: Batteries not lasting all day
I'd like to throw in an observation on this thread. My battery life is quite good on my Vibrant. Lasts all day easily but there are a couple of things to take notice of. First, I do not use any task killers or such, but I do check if there are any running programs with the built in task manager and stop them once I'm through with them. I've found that Voice Search and Web Access continue to run even after I've closed or backed out of them. Thus the need for use of task manager. But here's what I really found out. I've always charged my phone using the wall adapter with USB cable plugged into it. Never had a problem with battery life. Then for some reason, I decided to start using the USB cable attached to my computer. It would charge as normal and each morning it showed 100% charged. But after about 1 week of using the USB cable from the PC to charge the phone, I started having the horrible battery issues that I've read about. Extremely fast discharge. Leave at 8am and have like 50% use at noon. Crazy. So I started using the wall charger again and the phone has returned to its original state, easily lasting all day. Just a heads up for some of you guys having battery problems. No idea why this has happened but I've confirmed it. Maybe the Power Management thing on the USB ports on the PC?
I just saw this thread after a search on Google. I already posted elsewhere, but this looks like it might be the battery some of you are looking for.
http://forum.xda-developers.com/showpost.php?p=10055333&postcount=80
If nothing else, they also sell a 1600mAh battery which is 100mAh larger than the stock battery and still fits unter the stock cover. Good Luck

I just got the HTC One and the phone itself is great. That being said, I have one pretty large complaint...I've never had a phone that charges slower than this in my life. Is anyone else experiencing brutally slow charging speeds? Probably take 5 minutes for it to charge 1% which means it would take over 8 hours to get to 100%. Is this really possible?

I understand the battery needs to be trained but I've purchased hundreds of mobile devices in my life. Never has even an initial charge taken anywhere close to this long.
Is this using the supplied charger? Any processes running in the background that could be keeping the phone awake using power?

I know it helped with the old nickel cadmium batteries, but I've been under the impression that conditioning doesn't do anything with today's lithium ion batteries, that they are as good as they will get right out of the box.
Charge time Is a lot less than 8 hours normally. That said, it is still a slow charging phone compared to my previous few phones. However it is not too bad to be a complaint from me. We also have to be aware that the battery is a little bigger than the previous generation of phones, so it would take longer to charge anyway.

Yes this is using the supplied charger. Did a little searching online and it seems that there are others who have this issue. It was noted in the Anantech review as well as the following quote from the Droid Life review:
On a related note, the One takes forever to fully charge. I’m not sure why that is, but no matter what charger I seemed to grab when needing some juice, I found myself checking the status of the battery meter far more often than on other phones in my possession.

My phone needs about 4h to completely charge.
From Anandtech, the rationale is that Qualcomms fast charging is disabled in an effort to preserve the integrity of the battery's longevity; since you know, its sealed and has a repairability rating of 0. The Gs4 will probably crank that fast charge up and the user can replace the batteries as often as he deems necessary.
slow charging time seems a pretty fair trade off for a slow discharging time also right?

Probably this. In the end it is for the users benefit.
I was thinking, even my note 2 don't take more than 3 hours to charge. Heck even my 6200 hyperion battery takes about 5.

You shouldn't fully discharge. And my battery with the HTC charger does not that much longer than other smartphones but agree the S3 is a little quicker to charge.

From the Anandtech review:
What’s interesting however is that the charge curve gets the One to 85–90 percent under the normal 3 or so hours, it’s that last ten percent that takes forever
Click to expand...

Maybe they designed it so that the user would be discouraged to fully charge the phone, and thus completing fewer cycles?
If it's just the last ten percent that takes such a long time, I'm not too worried about it. There are few situations during the day that I'd have to charge the phone to 100%, other than an overnight charge.

It's a pretty big batter, to start. But you're probably not getting much current to the phone. If you charge from the USB on a computer, you're hardly getting any current to the phone so it's going to charge very slowly.
The faster chargers are 2A chargers. I have a 2A car charger that came with my Nexus One car dock I've been using for a long time and it's the fastest charger I've seen out of all of them. All of my phones (and friends' phones) have charged must faster with that charger.
I have a 1.5A AC charger too. It's still not as fast as my 2A car charger, but I'm also inside at that point, so it doesn't matter. But most chargers I've seen are 1A or less. Those are slow.

It's not the battery you're conditioning. It's the battery stats on the phone. The phone needs to "get to know" the battery to accurately describe its status.
Charge time should be a tad under 4 hours on AC, so I would say something appears to be wrong. Unless of course you're doing something heavy on battery) gaming/navigation) during charging.
what scm_crash said. pick up a 2A charger if you really need juice fast, otherwise it's probably designed to simply charge overnight for longevity
I always use my nexus 7 charger (2A) when i need juice on the spot.
It's ridiculous that people here think that the HTC one is not reparable ,so HTC designed a phone that can't be open ? What if you break your screen ? So instead of repairing your screen and be charged 180 $€£ for example ,HTC will charge you 599 for a new phone cause the phone is unreparable? That's ridiculous.HTC made the phone,HTC knows how to open the phone ,HTC will put phone back together again period.

It is strange that this forum suddenly has a lot of new negative misinformed posts just when the One is being launched in the USA.
Sent from my Nexus 7 using xda premium
actually it's not comparable coz the volume of the battery aren't the same.
you can also check the charger's specs , a 2300mha battery charged by a 1A charger, that's approximately 2.7 hrs.
still, for the first time it took more than half an hour to charge from 99% to 100% and the LED to turn green, that was strange. probably because I deleted the battery stat file for calibration
This is a topic that I don't think has been covered here yet, but is very important. Especially because we cannot replace our batteries.
I'm interested in finding out the best way to prolong the life of our batteries. In other words, I want it to continue holding a charge as close to specs as possible.
I am NOT talking about extending the use we get out of one full charge.
Upon googling, I found these two useful articles:
http://lifehacker.com/5875162
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
From reading those, this is what I gather:
We should not leave our devices plugged in at 100%
Best practice would be to use phone until 50% then charge
Charging to 100% actually causes the battery stress. Charging to 90% or so is better.
I think these few facts are right, since my Thinkpad has a function that stops charging at 90% and doesnt start charging again until below 60% (or whatever values you choose).
What I'm not sure about, is what has HTC done to help prolong battery health?
Does our phone automatically switch to using power straight from the charger at 100% instead of charging and draining the battery simultaneously?
Does any phone do that?
Battery health is likely the reason why our phones charge so slowly. Slow charging = less stress = better battery health.
I've also emailed HTC to see if they have any tips. Their manual contain no tips.
UPDATE:
Okay, so HTC got back to me.. amazingly quick. lol
Its a long email, which I wont paste here, but the one important part is this:
It is better to unplugged your phone from the wall once the battery reach 100% and once the battery indicates that the battery percentage is about 15% you should plug the phone to the wall charger.
Click to expand...
Click to collapse
That is what the guy said, word for word. The rest of the email diverges and talks about general battery saving tips.
So what the HTC rep says seems to fall in line with the three points I got from the articles I read.
Only difference being HTC recommends going all the way down to 15% before charging.. Hmm
Honestly, considering most of us get a new phone after a year or so, we're not going to see any huge hits in battery performance even if we don't follow these "rules". Not to mention I'm REALLY not going to wake up in the middle of the night to unplug my phone just so it doesn't stay at 100% all night. Just charge the battery in whatever way's the most convenient.

You might be right. But I bet there are a few people out there who are on 2-year contracts or just don't think they'll give up their HTC One so easily.
I personally love the design of the device and want it to last as long as possible.
I haven't felt this way about a phone since my Xperia X1, which I did eventually give up because I already replaced the housing twice, the mainboard was starting to have issues, and Windows Mobile 6 was just **** lol.
Anyway, under normal use these batteries should be fine for a bit. But unintentional abuse can wear them down faster than you think. At least thats what I get from these articles. And thats been my experience in the past with laptops and cellphones.
I too probably wont be waking up at night to unplug my phone or buying a timer to automatically stop charging my phone. But when I can adhere to these guidelines, I'll try my best to.

jonny68, no problem, glad this is useful.
These batteries have electronics to protect them, you wont be doing the battery any damage how you use it other than using your phone a lot and putting a lot of cycles through it. They never let you drain your battery 100% and they never let your charge 100%, it just shows 0-100% for the ease of the consumer. You cannot over charge your phone, if you could there would be a lot of issues out there.
Fact is just use your phone how you use it.

But that isnt entirely true.
Yes, our batteries now have mechanisms to stop overcharge and deep discharge.
But these same mechanisms do not provide longevity. Instead, our batteries are geared more towards providing the most use per charge without damage.
It is done this way for obvious reasons. It also means we have a choice about whether or not we want to sacrifice a small bit of convenience or capacity now, for a better battery later in time.
For example, this chart from the second article I linked shows that if you charge only to 90%, your battery can go through double the charge/discharge cycles before dropping to 70% health as compared to charging all the way to 100%
Quote from the article:
"Should I disconnect my laptop from the power grid when not in use?” many ask. Under normal circumstances this should not be necessary because once the lithium-ion battery is full the charger discontinues charge and only engages when the battery voltage drops. Most users do not remove the AC power and I like to believe that this practice is safe.
Like i said, this is all pointless, because 100% of us charge our phones overnight, and 0% of us are willing to wake up 3 hours into our sleep to unplug it at 90% or 100%.

Reading voltages is one of many methods of determining how much charge is left within a battery. Hence the other column in that table.
You cant just stick a meter on a battery and read how many mAHs are left.

Right, and that is true for some laptops as some of them do tend to have more sophisticated battery management software/hardware. I mentioned my own Thinkpad and its functions in this OP.
I was curious as to if our phones do the same thing as laptops; disengage the battery at 100% charge and run off AC only. But it does not, as per HTC's reply suggesting phones should be unplugged once at 100%.
And for your other point, I already addressed that. I'm not saying this is essential or that everyone should follow these guidelines. But to some people this does matter, and this post is for them.
As for myself, I'll use yesterday as an example.
I got home from work at around 6:30PM, my phone was down to 30-40%, so I plugged it in.
Before I went to bed, the phone had hit 93%, so I unplugged it and left it there with wifi on.
I wake up, its lost like 3-5%, no big deal.
Around lunch time its dropped to 30% at work, so I plugged it in.
It reached 89% a few minutes ago, so I unplugged it.
So when its convenient for me to do so, I follow these guidelines. If I know I have a long day ahead with no access to a charger, or if I need to charge overnight, then so be it, I'll let it sit at 100% until I have to leave.
Technically speaking this is all correct and a guideline to try to follow. That's all. If it's impossible to do, the phone will be okay. That being said, I am of the belief that if there is a better way to do something, we should at least try to do that. I for one love this device and may never sell it. This is one of those iconic builds that I wonder how much more of its class we will see. Even right now as the music pours out of these front speakers, my love for it grows.
I just wanted to add my 2 cents. And this little tidbit:
Every 100mv less than full charge you apply, will double the lifespan of the battery. So, a rough approximation,
Charge the phone to 100% (4.3v) , discharge to about 15% You'll get roughly 250-500 cycles.
Charge to 90% (4.2v) down to 15, you'll get 500-1000 cycles.
80% (4.1) 1000-2000 cycles.
Cycle count will increase by avoiding deeper discharges...
In a perfect world, you could potentially get 2000-3000 cycles by
1. Charging to 80% or ~ 4.1v
2. Avoiding discharge below 30% or ~ 3.6v
3. Avoid extreme temperature changes and prolonged exposure to temperatures above 45c
Most of this comes from personal experience and much research. Check out battery university if you get some time.

By last do you mean until the battery reaches 70% maximum capacity? Honestly, at 1000 cycles, thats already good enough since thats 3 years worth of charging at roughly 1 cycle a day. I doubt I will keep this phone past 2 years.

That's exactly how I feel, and the reason why I started the thread :victory:
Your figures fall close to the ones in the articles, so it sounds bout right.
Im curious though, does unplugging/replugging have any effect on the charge/discharge cycle?
For example, if i'm charging my phone but i need it for something, I unplug it, use it, and plug it back in.
That shouldn't have any effect am I right?
You have to define what you mean when you talk about how long a battery "lasts".
We're specifically talking about deterioration in capacity over time.
The battery will "last" for 100,000 cycles in the sense that you will still be able to charge it and it will still be able to power a device on its own for a period of time. The question is how short does that period of time get before you say "this battery isn't useful anymore"
This came up in another thread and the threshold discussed there was 80% of original capacity. Apparently HTC rates the One's battery "lifetime" as 500-700 charge cycles until the battery capacity drops to 80% of its original level. (You also have to define charge cycle: charging from 0-100 or anything that adds up to that, such as charging from 40 to 90 on one day followed by charging from 40 to 90 on another day - counts as one "cycle".)
So this battery could "last" - in the sense that it will still have 80% of its useful capacity - for 3000 cycles if you follow some of the more conservative approaches above.
I don't know how typical my behavior is, my last three phones were bought via two year contracts, each phone was replaced after about one year, when the next-generation model appealed to me.
Don't imagine too many buyers of "flagship" devices keep their phone for over two years.

We're specifically talking about deterioration in capacity over time.
The battery will "last" for 100,000 cycles in the sense that you will still be able to charge it and it will still be able to power a device on its own for a period of time. The question is how short does that period of time get before you say "this battery isn't useful anymore"

Hm, yea I should update my OP with that info. The articles I referenced seem to define a battery's lifetime as the number of cycles it can go through before hitting 70% of original max capacity.

Not sure, but in the past I've always seemed to kill my phone's batteries before I replaced the phone itself lol.
If I look back now, that was probably because I always drained to 0% and let my phone stay plugged in at 100%. So basically I was always doing the worst thing possible, short of literally cooking my battery >.>

I really don't think that's it. I have done that with EVERY phone i've had, GS3, Nexus, etc. After a year i didn't see any major battery difference, and I plug it in at least once a day, sometimes 2 times.

The difference may be how much we use our phones then, because with my last phones I typically used my phone quite frequently at work since many websites are blocked. Including open source code sites which actually help me with my job... stupid corporate proxy.
Anyway, I used to leave my G2 and Photon Q plugged in all day at work and at night. So thats 16hrs of being plugged in per day... Probably wasnt good for them.
But hey, if you're right and I'm wrong, I'll be even happier cause that means my battery will be fine no matter what I do lol.
However, battery deterioration isn't a myth, and it does happen. Only question is, how much does it happen.

Ya i tend to just leave it overnight for about 7 to 8 hours. Sometimes during the day i might plug it in for an hour or so to grab some juice on my s3, something i haven't had to do on my One which is awesome (get about 2 days worth). Battery deterioration definitely does happen, but hey, if I have enough juice at the end of a year to still last me a day, I'm happy
I'm always on a 2 yr contract, no need to really worry about this, but good info none the less.
dont worry op .. ill put my battery in the many " to be taken care off" list.
ill make sure its in the list.
somewhere
If the ONe is anything like the HoX, the charger stops charging at 100%, then lets it drop to 95% before restarting trickle charge. However, the 95% battery state isn't immediately shown on screen, so many people use their phone then see a whole 5% jump downwards almost immediately. I haven't paid much attention to the HO yet, so I can't comment
I've got extra batteries, so that isn't an issue. Could a mod be made, or an edit of a file, in a text editor, so I could disable this behavior?

+1. I've always thought this but each time I forget to post a request about it lol. I too would love to see this mod.
I always have an extra oem battery with me too, but I'd also like to see this. I generally take my battery below 5% if I'm going to bed for the night soon and don't want to pop in a fresh battery and the battery has a little power left, I'll milk it

I too would love to make this a reality, especially because I have the ZeroLemon 7500 mAH battery. 5% left with that is fairly substantial, and thus extra annoying to have to use it dimmed.
You do know that taking a lithium battery that low all the time is very bad for the battery. If you got spares why would you drain it like that? Most lithium batteries will fail after around 500 complete charge and discharges but can last 1000's of partial charges.

I have heard this before but so far I have not seen proof. I have been taking my batteries down to zero since the S1. And my daughter is still using the S1 with the original battery in it. And it still gets more than a days charge out of it. And I have done the same with the S2, S3 and my S4. All of which are going strong.
I know mileage varies but after four phones it doesn't seem to have an impact. And if it does have any impact it is very negligible. Enough that I can't tell.
Take the S1 for example. It was purchased on launch day. So it is three years old. That means it has probably close to 1000 charges. It has degraded some but that is normal for a battery that old.
Also look at it this way. If I charge my phone once it hits zero I am charging once a day at most. So 500 charges equals 500 days. If I charge my phone partially I would charge it at least twice a day, probably more. So 500 charges would be 250 days. So it would all work out close to the same in the end anyway.

Plus you wear out the charging port more (obviously) when you keep plugging it in/out.

It is correct that lithium cells can be damaged if discharged beyond a certain point. However, most batteries containing lithium cells are "smart" and contain circuitry which will prevent the cells from being discharged (or overcharged) to the point at which damage will occur.
anybody know when the time is best to recharge the phone battery?
because i heard that lithium battery should not empty before recharge... and if i empty battery (1%) , this damage the battery

If you do it to often it will shorten the battery life
wait till it asks You to charge , I guess that message is for this . Connect your charger ! under 15% Phone tells You itself

Above are all incorrect!
Charge at 50% and you can do it about 1500 times.
Charge at 20% and you can do it about 700 times.

I hope you dont do that for all your phones as it will destroy your battery way sooner. Charge it when it reaches 50% and you can do 3 to 5 years with the battery at 24/7 use. (Instead of the 1 to 2 years when draining the battery).
Yes, it is recommended to charge the battery when it below 40% and disconnect the charger when it reach 99%. Do not overchange.
There was a big test I did read and the best was to keep it between 40 and 80 percent.

charge it when it prompts you to charge. at 19% you start getting the first recommendation in lockscreen, then at 15% you even get an annoying prompt.

Are you guys seriously sitting and watching until the battery goes down to certain percentage? And for what? Battery is easy to replace and not that expensive, it has a circuit to protect it from over and under charging, to avoid the damage and you get many more shallow charge/discharge cycles than deep ones as already mentioned. I charge my phone daily in the evening at my convenience, usually before I go sleep regardless of what's left (unless I use it so much it can't last until evening), so by the time I go sleep it's 100% and by morning it will be around 97% and normally last me whole day. I've been doing this for yrs and for example my 4yr old Nokia I gave to my friend, still lasts him couple days of light use on original battery. I wouldn't worry about it at all. Every few months you may want to fully discharge it to lets say 3-5% to have the meter calibrated and maybe clean the contacts with alcohol every six months or so, but that's all the maintenance my battery will get or need. If it fails before the phone, it probably had some factory defect or something, but no big deal as long as there is replacement easy to buy and with so many millions of notes sold, there should be.

Couldn't agree more, I charge mine on a evening regardless and phone gets me easily through a day. If I notice a massive drop in the battery not holding a charge then I will buy a new one. More important things to worry about in life than watching my percentage for the battery.

That is good as a principle but the numbers are still rather big and depend even more on the charging current - if you charge (even) from 50% with 2000 mAh it will never last 1500 recharges - that is why Samsung has slightly improved the Note 3 recharging algorithm so as to use (variable) lower currents (even if the charger is 2000 mAh), and also why it is still far, far better to recharge from a very good USB at under 500 mAh (actually 450) - and indeed preferably from over 40%.

As long as the charging current is lower then 1C (1 full charge for the note3 its 3200mAh) its not a problem and wont shorten lifetime.
But yeah charging at lower currents is better, but more due to less heat and induction.
Anyway its just sad that other people with little to no knowledge about lithium batterys are giving advice, and WRONG advice at that.
Just read the link i posted in previous post (page1) there are the facts. Dont believe just anybody, people are stupid. (yeah im people too )
The chemical reaction will be less when battery is drained and is hard to recover.
But if the battery seems dead, put it in the freezer for 2 or 3 hours and it will be recoverable.
Theres more to these batterys than people think.
