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?

Bro, before you make assumptions, give the battery a couple cycles to settle itself.

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

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.

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

Sorry I didnt mean to put the thread in the wrong place but this section seems more tech than others. Yea I figured it wasn't just my phone, I just wondering why HTC phones took longer to charge. Thanks for the help
The way Li-Ion batters are charged is not as simple as alkaline or NiMH - cell balancing, over voltage, under voltage, temp, authentication, etc.
You wouldn't want this to happen: http://www.youtube.com/watch?v=QJCZ4ayioCU
sounds like you are the type of guy who would complain about having to put premium fuel in his ferrari. one droid and inc are 2 totally different pieces of hardware. if you had reliable data to support a claim like htc phones take longer to charge then i might believe it, but u dont so dont make that claim. i have a blackberry storm (business phone) and inc (personal) i literally almost never use the BB and if i do its for calls lasting less than 10 mins. Yea it charges faster than my inc and yea the battery lasts longer, but i do way more on the inc and that takes battery and charge away. when i used the BB for everything before i got the inc, it was the same situation. so does that mean bb take a long time to charge or the battery sucks? no

Was that necessary? Yes he asked a question in the wrong forum, yes it was a poorly worded/thought out question but seriously? Just made yourself look like a big douche...
Just sayin'
The way you use the phone has nothing to do with how long it takes to charge. Could be different voltages for the two phones. The lower the voltage, usually the longer it takes to charge. You'd have to look at your adapters and see what the output voltage is on the Inc. vs Moto. Might answer your questions. Otherwise, it's probably how the trickle charge works differently on the two phones....
**DO NOT USE A HIGHER VOLTAGE CHARGER** !!!!
Also if you have a TON of stuff running on your phone, it could be a lot less "idle" than you think while it's charging.
I think the trick is to charge your phone at the perfect times - like while you are driving to work (especially if it's a long drive) or while asleep. Who cares how long it takes while you are asleep??
Droppin' some science!
This is just technical information for anyone that may be interested, I don't know if it will exactly "help", but it should answer the question of the post (also please keep in mind that these are two phones from two different manufacturers so even if they are running the same OS, the way they manage and consume power would be different regardless).

The data cable is what comes in the box with the AC head (which has no cable but a USB connector).
I use the same data cable connected to a number of different computers, notebooks and netbook and charge all the time.
When connected to a computer, it is slower to charge, but it charges just fine.

I think he means that he's using the cable with the AC head, and it takes 4 hours (as in, he's not using some off-brand charger from Radioshack, or something like that).
My DI definitely takes longer than 2 hours as well, Not sure the exact %'s, but at home today had it plugged in from when I woke up until I left for work (about 2 hours) and it seemed like it went roughly from 10% to 80% only.

Exactly. PC/LAptop USB power is just as good as wall-power, it's just a lower amperage, something like 500mA to the AC head's 1A/1000mA. More amps means faster charge.
I believe our DI batteries are 3-cell, judging by the four terminals on the battery: 1 (+)power, 2 (+)power, 3 (+)power, 4 (-)common ground. I don't know what sort of battery the Moto Droid has but it's a motorola, so it's gonna fail soon anyway (sorry, I'm just sayin). I know the G1/Dream battery was 3-terminal, and when some went to a Seidio 2600mAh extended battery (twice as many cells), they had to charge it 8 hours when they first got it.
Obviously, turning the phone off to reduce the load on the battery, using the wall charger, and making sure you're not short-charging all the time will reduce charge times overall. Judging by the battery life I've gotten so far and what a monster this phone is compared to my G1s, I'm more than happy to wait an extra hour with the phone off, that's what Google Voice is for

About 3 hours here which is fine, charging from the supplied charger connected to electricity mains. Are you charging via the USB connector? It will take a lot longer, something called trickle charge or something like that.

I noticed this when my brother bought the same phone. His takes a ridiculous amount of time to charge, maybe 1% per 10 mins or so and it gets really hot while doing so.
Mine on the other hand doesn't get hot at all and charges at least 3 times faster than his.
please state charge state, ages, fast normal etc.
firmware and revison thanx
The charger shipped with my S2 has only 700mA...
especially if you are using the phone (worst: gaming) while charging it seems to get never finished . I guess the current drain doesn't left much for the charging.
So i'm using my old HTC-chargers (one AC=>USB and AC=> MicroUSB) witch both supplies 1000mA.... ~43% more in theory
Hard to say how big the advantage is in fact, but it makes a difference.
Also keep in mind, that a standard USB-Port supplies max. 500mA, depending on other USB-devices even much less. I also read that the charging result is "better" if you not using it in the meantime.
You can buy USB-Chargers up to 2100mA (e.g Amazon), but i have doubts that this will be improve the charging time because on the type-label behind the battery is written Rated : 3,7V-1000mA. Even more current wouldn't not damage the device (afaik!!!), the device or the battery could not charge faster.
Maybe somebody knows about what is meant by the the 1000mA exactly. Would be nice if the device could be charge a little bit faster.
Otherwise i am going to buy a 2nd battery with an external charger.
greetings
I found this on Android Forum
lotus49
USB charging is slow on the S2 as it uses trickle charging
"Trickle" is an exaggeration.
The phone can tell whether it's connected to USB or a mains charger. If the latter, it limits charge current to 650mA. If the former 400mA.
It will charge faster on the mains but not loads faster.

My other cell phones are fully charged in 2 hours, more or less. And yes, I'm considering selling it, because I like to use my gadgets and the SGSII doesn't admit an intensive use without running out of battery, unless you have a second battery.

Yeah, I do sleep more than 3.5 hours per day and I try to charge it every night, but the problem is when the phone runs out of battery in the middle of the day and you don't have 3.5 to spend in charging it fully.
I think the iphone 4 is only a 1420Mah battery if I remember correctly while ours is 1650. Sure, it takes perhaps another hour to charge but I don't find it a big deal. It does appear that the first 50% charges faster then the second half as well but that could just be my imagination.
I have read that Samsung phones charge slower so that the battery life will be longer than that of those other phones such as HTC where the phone charges a lot faster. I'd rather get another year out of my battery and it take longer but do admit 3.5 hours does seem like a while.
this topic has been covered. teh SGS2 battery driver is capped at 650 mA for wall charging, 450 mA for USB charging. this code resides in the battery driver.
someone could compile a new kernel with this value raised. other phones like the nexus one charge at 980 mA for wall charger, 480 for USB.
samsung capped charge current, likely for heat issues, nobody really knows.

The note is a disaster for me when it comes to charging.
If your battery is low and you start charging it but using it at the same time, it doesn't get worse, but it doesn't get better either i.e. actually charge the thing, it just holds its own.
I have got to say I am not impressed with this!
I am not facing such problems. Charging takes pretty long yes but not as bad as you said. A larger battery will of course need a longer time to charge. But I wonder sometimes too if it's the battery problem or the charger output problem and if there's a way to speed up the process.

I think it is more to do with the actual charger, seems like a trickle charge or something.
Yes if charging and using at the same time you would not expect it to charge as quick, but mine doesnt really charge at all, just stays the same.
My acer iconia will charge like lightning even when i am using it, smaller battery or not it still charges!
This was one of the things i was looking forward to with the note, but this slow charge seems to make it more or less the same as what I am used to.
I have the usb plug which comes with the kindle, might it do a better job?
If anyone manages to find a proprietary charger which can produce better charging I will like to know too
That is common the charging is very slow and if you are playing HD games then the charging is almost in negative. May be its because of the voltage of the charger inputs and it is to low. Samsung must have done it for a reason may be its because of the proprietry port or the battery itself we do not know but we need to live it
Agreed, charging this thing takes a long time. Keep in mind that the battery is 7000 mAh and the charger is most likely a 2 amp charger, pegging the charge time at around 4 hours with no other losses. So if you're using it, it should take even longer.

No such issue here. I charge to full capacity while using all the time.
I get what he's saying. Because it draws so much power when you're using it; having it charging at the same time doesn't move the needle much. For example, if you're watching a movie while it's charging you'll probably be at the same point battery wise when the movies over. People complain about this all the time when their using their devices as a GPS. In some cases not only doesn't it charge but it actually continues to drain so you're worse off from where you started. We're using 21st century toys powered by 20th century battery technology.

This is a better way of saying what I mean, thank you.
I also have to say one thing I do not like doing is turning the screen brightness down. After all we all get these things as they look so good, so I am not going to make it look worse when I am using it, what would be the point in that? Its a bit like saying yeah my battery life is 14 days but actually it is on standby for that time lol...
Anyway, I still believe it should be better and the primary cause is the weak charger for what ever reason sammy decided to make it that way, but its not a good thing.
It seems like I remember someone recommending a charger that was more powerful so the note would charge faster. Can anyone confirm this?
What a fail thread. If you know ANYTHING about charging, you would know why this happens and why this is NORMAL.
But why even search or educate oneself, let's post a thread on XDA and whine a bit.
It could be worse. It takes six hours to charge a N10.
I dont face this problem i charge mine when surfing the wep
On a slightly related side note, doesn't it suck that the brightness just turns down completely when the battery is low?
The zslower charge rate protects the batteries life ,reduces the possibilty of heat and battery damage trickling insures a full charge
if you don't want your screen to dim don't use the power saving setting.

Wow! many friends?
Anyway moving on.. so i just got my note 10.1 about a week ago, loving it but saw that while plugged in it was not charging at all while i was using the tablet and never quite getting to 100% overnight. By not charging while using, i mean to say that it was actually discharging. Yes of course i am using the stock charger and cable.. and even stock note.
so just tried something silly. Unplugged and plugged the usb from the block repeatedly about 5 times. Now its not only recognizing and charging, but charging relatively quickly even while using. To test, i unplugged for about 20 min and plugged back in. Same great results.
Just thought i would share instead of hoarding my new found knowledge like others..
Quick update: it charged about 10% in 20 min.. Nice
I don't charge mine - I paid cash for it
Cmon, lets give the credit where credit is due.
I no longer have to worry about battery charge thanks to this new fast charge thing. 45 mins after having a low battery I'm at 80%... thank god battery charging has finally progressed to this.
I use my phone for music / radio shows all day long. I can't tell you how happy I am to have this fast charge thing.. on the boat, in the car, at work at home, a 30 min charge and my phone is ready to go for HOURS!
Thank you to samsung and the note 4 for FINALLY putting a phone out there that is awesome!!

I agree but I rather swap my battery. When I get down to lets say 5% I don't have to worry about plugging it in. It takes less than a minute to go from 0% to 100% and it's less strain on the charging port and circuit. Plus if you still want to use the phone you don't have to be tethered to a cable.
+1 I love it. Swapping out the batter. LOL Not so much.
Battery swapping really sucks if you have a case on the phone. I vote for fast charging. Beautiful thing! I just need to get a fast car charger and I can charge my phone fully during my commute to work.

The only thing I could say is, possibly, the reduced battery life span due to the additional charge cycles. But charge cycles for modern Li-ion is already really high. But even if I were to entertain the fact that the battery might need to be replaced sooner, who cares. You are buying another battery NOW, vs the possibility of buying another battery in a year or so.
As far as personal preference goes, if a spare battery is your thing, go for it. But please try not to perpetuate the idea that the fast charging circuit or battery can't handle the charging.
I'm more than happy to go over the physics and electrical theory on how charging works. You might be interested to know that in a lab setting we can get charging rates as fast as 1 minute per 1000mAh with minimal heat build up (the major hurdle in improving charging rates)
Fast charging is nothing new. A similar concept are large capacitors, like a camera flash. They charge in seconds. The major engineering challenge is controlling the discharge rate, in most cases the heat build up is limiting factor.
Don't be surprised if the note 5 charges in 0 to 100 in less than 5 min.
Fast Charging + Killer battery life = One Happy Customer

i love everything about this post, btw. i'd love to know the physics and electrical theory if you ever want to share. it would probably help me to understand which is better for the phone, not that i need it right now, but i'm sure it would be beneficial to have that knowledge. i am one that is a fan of the fast charging, but i've also been looking at Samsung's spare battery charger too. the Korean Note 4 variants actually came WITH the spare battery charger (lucky ducks) but it's going for $45 ish right now on Samsung's website. might not be a bad investment at all, even though my battery life is averaging 12 - 15 hours on a singe charge.

This is true. I had an Energizer battery charger that could charge my AA or AAA batteries in 15 minutes. They got very hot though. This was in the 90's.

I had something like this as well. Mine had a fan on it that would attempt to keep things cool. I have an Ego lawn mower that can charge the HUGE battery pack that goes in it up by 50% in 15 minutes, and it sits on a big charging base with a huge, loud fan. That's a little different than charging a cell phone battery or AA/AAA batteries.
+1 on the fast charge thing. To me, that's revolutionary.
Fast charging is awesome, but I really don't use it. My battery life is so great the it easily lasts me the whole day with moderate usage. I usually end the day with 30+% left. The fast charging is an awesome feature, but i really have no use for it.
Someone was saying having fast charging checked depletes battery quicker. Ain't that some bs?
Has anyone given any numbers as to how slow / the rate of wireless charging is on this phone? I love fast charging but I want wireless charging as well.
I agree with a couple of these posts. I have moderate use on my phone and usually end the day at 40% or higher. However, I love having spare batteries that I can just pop in and be at 100%. Just ordered 3 plus wall charger for $20 shipped. Hard to beat having 3 full charges at hand if you don't have a chance to plug in for a while.
Battery life is great on this phone........period!!!

I believe most wireless chargers are 1 amp output. The stock wall charger is 2 amp so I'm guessing it would take about 2 1/2 to 3 1/2 hours to fully charge on wireless,I'm not expert though.

I do not doubt the usefulness of it, and I know it will come in handy some days. It's just my normals days I have battery to spare.
I went back to the slow charger for overnight charging and battery life has been pretty darn good. When I use the fast charger it says it gets to 100 quickly but I feel it drops down way faster. Anyone else feel this way?
yeah, same happened with the note 4. I only use the fast charger when i need a quick charge. I use my old note galaxy tab s regular charger overnight.

Yeah. Fast chargers are great (the one included with MXPE is superb) but they're not meant for overnight-leave-your-phone-on-the-charger-for-6-or-7-hours-while-you-sleep type charging. Technically, the less you leave your phone on ANY charger after it reaches 100% the better it is for your battery.

This used to be true, but I thought it's been debunked with current battery technology. Recent source anywhere?
No source... IMO. (And the fellow XDA members that replied to this thread)

He was asking for the source saying it is better to disconnect your phone once it gets 100% battery...
It's been proven it has no ill effect over time, and after charging to full it will stop charging until it discharges enough to need a trickle charge, at which point it will trickle back up to 100% and repeat the process.
If you have ever had a battery pack shut itself off after charging your phone to 100%, it's because it finished charging and didn't discharge quickly enough before the battery pack shut off.

I never use my rapid/turbo/quick charger (or whatever it's called). I only use the regular old overnight charger. I get great battery life. I know for a fact that heat is bad for all electronic components including batteries as can be read about in numerous articles on the subject. However, I also wonder about rapid charging to 100% why would the charge not last as long? Unless something that is reading the battery capacity is not accurate when the battery has been rapidly charged?
I don't have any scientific evidence. I just find I get better battery life using the old charger and noticeably worse battery using the rapid charger
I use the rapid charger and the battery life is the same with or without it.

I agree with this, my phone was on 15% and I was about to fall asleep so I left it plugged in for about 9 hours, and it was almost dead with 2hrs SOT and 5 hours after being unplugged. But if I unplug it when it's at 80-90% it lasts me almost all day and into the night.

Same here. Rapid charge is awesome, and my battery life is very good as a business user.
I agree that fast charging is great for a temporary quick charge but not good using it to get your phone to 100%
