Why does it take so long to charge?

I just have one question. Why does it take so long to charge from 10% to full? It takes my incredible about 2 hours and 15 minutes to charge, my moto droid 1 hour.

Wrong Thread
Doesn't belong in the Dev. thread. As for your question.... your comparing apples to oranges. Mine takes about as long... so I don't think it's you. Probably the way the phone was designed.

agreed on both points, 2 hours seems pretty reasonable to charge IMO

Yeah

People forget that back in the day it used to take 4 - 6 hours to charge your device, and it'd drain after about 3..... spoiled brats! LOL

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

UGH...

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).

You don't want to charge with the data cable. It's intended to only maintain battery life when tethered, not charge it.

Huh?
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.

All kinds of misinformation on this thread. Any charger that complies with USB standards is going to be 5V, no more no less, whether it has a microUSB tail on it, no tail, or a rat tail.

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

nexus s wont turn on after not using it for 4 months

ok i switched to another phone and i stooped using nexus s for like 4 months i was planning to sell it and today i took it out it does not even turn on. does not take charge. it was perfectly fine... what happened?????

Maybe the battery got killed.

does it do anything when its plugged in?

pull the battery, put it back in, try charging, oddly enough sometimes works.

it was perfectly fine until you left it for another <del>woman</del> phone. how did you think it would react?

Try charging it connected to a computer. Often wall chargers can't charge a device that is completely dead

A charger is a charger. If both are working properly then one won't charge better than the other. One may charge faster than the other. Perhaps the battery has a dead or weak cell in it. Try swapping batteries with someone and see if your phone will charge it. Give someone your battery and see if their phone charges it. Try their charger on your phone. Try your charger on their phone. Process of elimination.

Think about it..why would one charge faster than the other? well because the one charging faster is being given more current. if the battery is dead and isnt able to charge with the weak charger, maybe the one giving out more current is just enough current to get it started. You can compare this to jump starting a dead car battery.

Yeah, no. It doesn't work like that at all.
Chances are the battery is just totally dead. If you have some sort of a charger that can charge any given Li-ion battery, hook it up and see if it charges. Otherwise, you're going to have to beg/borrow/steal/buy a new battery.

Yeah, a dead or weak cell is just that. I might be wrong but once that happens, there's no way to fix or revive it that will bring it back to normal. Check into it. If it turns out to be a bad battery, I'm not 100% sure so don't quote me, I thought I might have read the ns uses the same battery as the Samsung moment. If this is true, please research it first, then it shouldn't be very expensive to replace. I highly suggest you get an OEM original Samsung battery. Aftermarket usually never hold up as good as an OEM if both batteries are the same ratings. I've had OEM batteries outlast aftermarket ones for uptime even when the OEM was rated significantly lower in output. Example: I had sprint official battery that was extended 2200 for my evo. I had aftermarket 3300 for the epic. The evo would outlast the epic when both had a full overnight charge. Now before anyone says that's not a fair comparison, consider this. When both phones had OEM 1500ma batteries in them, the evo would ALWAYS die before the epic would. Noticeably sooner.

What a cluster this thing is to charge...

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.
Sent using Tapatalk2 from my Note 10.1; the choice of Royalty

For all those facing the slight unresponsive screen please change the source of power, I had mine connected to UPS power supply as soon as I changed and connected it direclty the problem was gone.
Even if you read the user manual of Samsung Note its says thats one of the reasons

How Manhattan hours per day do you use the note? With a 10hrs battery life I find an overnight charge is sufficient

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

Slowest Charging Phone I've Ever Used

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?

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.

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

Charging my S5 with non-OEM cable?

Hey guys, yesterday i noticed something strange: it took 3+ hours to charge my S5 from 8% to 100%. I remember that it used to take around 2 hours at the very maximum from 0% to 100%. Then i remembered that my cable with which I'm charging is not the original one (it got cut long ago) but the charger itself is the original. Is something wrong with my battery? Is the charger bad? Should i search for an OEM usb cable? I don't mind it if it charges for longer as i charge it at night but still, this got me a bit worried that it can degrade my battery overall by keeping it hot for longer than needed. Thanks for any answers.

My phone gets hot when I use a non OEM cord as well. But its never hurt my phone. I've been doing it for probably a year now. As for the longer charge time is it suddenly taking longer with this cord or is it taking longer because you are now using the cord?

Well not sure as i mostly charge it at night. But my phone's battery life is normal while using it (atleast for now), just curious why it takes so long to charge.

Different cords have different capabilities depending how they were made. There's even some that only give power and no data transfer. Samsung makes fast charge technology for their devices. Other cords may or may not support it.

It comes with the USB cord as well. And I'm pretty sure fast charge tech is both the handset and the charger itself. I read the charger is 1.5x faster then a normal one even if its not going to a device with fast charge and 2x faster if it is. I didn't mean to quote myself either. Lol
