It takes mine ages. I can leave it plugged in for hours and it only charges a bit. Right now Battery Monitor widget estimates 8 hours on "AC" and 12 hours on "USB" for a 100% charge - 3/4 hours from 64%. That's slow, no?
I only get +2-400mA (341mA right now, sometimes less, or more) when plugged into my 5v-1A AC charger. How about you guys?
Any one else got charge times from a program like Battery Monitor Widget?
Takes about 4 hours from 1% to 100%
my HOX is charging.. i plug it at 9% 1 hour and 40 minute ago.. its 71% now..

That's very very slow. Check your cables, are they frayed? Cos I'm currently using the cable that came with my Desire Z and it's starting to fray pretty bad, and I'm only getting about 300-400mAh charge in. Used to charge at around 750+. I switched USB Cables (same charger, just different cables) and my charge rate jumped back to 750. Do note that charge rate slows down the closer it gets to 100%.
Mine took almost 3hrs for 0 to 100% charge.
3-4 hours from 5% to 100%
On the USB in college I get 20% is 2 hours lol on charger about 3 hours.

That's weird then. Maybe I should buy a new cable. Do most of you get 700mA+ readings when charging?
The cable is very new, but I did get it from a shady seller - maybe it has a problem. I will get a new USB cable this evening.
It COULD be the problem? That's only from my own testing though. Try it with a friend's cable or something. Nokia and Samsung phones use the same Micro USB to charge.
Mine will go from 2% to 100% in 3 hour 5 min with an USB charger of 1.5A output.

Unfortunately the HOX is limited to a 1A input charge /:
i'm at my wits end, i bought an HTC one X today, and plugged it to the charger cos it was 7% of energy, it's been off for 3 hours and i turn it on and it says 8%, i'm using the cable and the charger that came with the cellphone, what could i do?, i even got a message while running the setup procedure that the phone consumes more energy than what it receives via AC, what to do? i'm worried

You've got a misbehaving app somewhere. Restart your phone and try again.
with the original charger and cable, it takes me roughly 3 hrs to fully charge my one X from 10%~ to 100%
with the cheap cable I bought and the Iphone charger, it takes me 4 hrs to charge from 9% to 90% ~ about 5 hrs to fully charge ~
I don't use my laptop's usb to charge, and I believe it will take much longer ~
With the official HTC cable that came in the box its taken me 3 hours to charge about 40%. Please someone tell me this is faulty.
Also the battery has never lasted more than 2hours 20 mins on screen with medium/heavy usage. and no more than 1 hour 30 with heavy usage (HD Video/streaming)
ALso when i unplug the charger at 100% it drops down to 90% within 10 minutes and then continues to plummet. I got around 6hours off screen time with music playing before it died.
Anyone have this issue?

The same thing happened to me today. I've noticed charging from a computer's USB gives a higher charge amperage.
I just ordered a 2A USB charger, but I also found that if I power off the phone and charge it, it charges very quickly.

That sounds like a serious problem. I would send it back. Although, you should poke around and see what's consuming all the energy.
Charging times without looking at the battery monitoring application reporting where energy is spent does not help much to understand where the problem is.
If the phone is really idle with good GSM coverage, no particular GSM activity and Wifi switched off, then more than 2 or 3 hours either shows that the charger isn't powerful enough (could happen with a car cigarette-lighter->USB charger or any charger that delivers less than 1A/H), or a faulty charger or battery.
If one has good charging times when the phone is switched off, then the problem is more likely related to the software running in the phone, fiddling with the phone while it's charging (keeping the screen on) or because of RF activity (GSM, Wifi).
So first switch the phone off, charge it at 100%, look at the time it took and if it's okay then look at the battery monitoring app to understand where energy is spent when the HOX is turned on...
what apps or widget do u guys use to see how much current(mA) is being charge to the phone?
hi all
mine charges from 25% to full in a little over 2 hrs
thats with the htc charger that came with it an the usb supplied by htc .... i have other leads that i used with my old deisre (non htc) and i gfet a very slow charge time .... i have got from ebay som high quality leads (if 2.99 post free is high quality) and they charge quickly so id say the onex is quite fussy over what leads you use to charge it

Mine take over 2 hours from 5% to 100% using stock wall charger,,, 3 to 4 seen like a lot.
The answer is... it depends.
If you're charging with the phone on, it will take longer, if you're charging via a usb port, it will take longer.
If the phone is off and you're using the stock wall charger, you're charging at a maximum of one amp. If you have a stock 2100mah battery (2.1 amp-hours) and your charger is 100% efficient (never happens), the best possible 0-100% charge time is... 2.1 hours, it really is that simple
Now, you're not getting 100% efficiency, plus the way lithium batteries charge, at around ~50% capacity, the charge current steps down gradually from 1 amp to nearly 0 amps, so your real full charge time with phone off is probably going to be closer to 4 hours than 2. The step down is necessary to avoid over-charging. The logic (usually in the battery itself for phone batteries) to determine full charge is when the battery reaches 4.2 unloaded volts. Charging current will increase the voltage reading, so as it gets closer to full, charge current is gradually stepped down to maintain the 4.2 volt full charge state. As the current approaches zero and volts stay at 4.2, the charge controller knows that the battery is full.

3 hours is the average using the included 1amp A/C charger.
Charges 10% about every 15 minutes for 0% to 90%, and charges the last 10% in about half an hour.
(don't bother trying to charge using your computer's 0.5amp usb port, though; takes forever, especially if you're using it while charging)
There are reports that the charger that came with the s3 is garbage.

The charger that comes with the S3 is NOT garbage. I tested charging times against a "better" 2.1amp charger about a month ago and there was no difference. (If your custom kernel supports "fast charge", then there'll be a difference, but your battery will suffer. Better to stick with 1amp)

Flashed JB today. Phone currently charging. Started charging at 2%, now at 41% and it's been 45 min. Estimate completion time, 1 hour 45 min.
So the culprit is not the USB charger, but rather something I had installed on ICS. I suspect it is the launcher I was using, which was GO launcher. Prior to JB, i was using apex and it was charging a little bit faster than GO, but still wasn't acceptable. I think it was 3ish hours for full charge.
My current JB setup is pure stock launcher and apps.
With stock charger it takes my phone approximately 2.5 hours to go from 5% to 100%.

I can confirm that,my AT&T S3 has been charging with that charger for 6 hours and I am still showing a 50%,so I had to grab a Motorola charger and it went up from 50% to 73% in half an hour.
Freaking Samsung,there's always something.
I'm on Slimbean 4.2.1 RC1 w/ lean kernel and my phone will usually last (with average daily use) about 3 days on one charge. The rom/kernel supports fast charge so I can get it from 0-100% charge in under an hour and a half. On stock rooted rom I was getting maybe a day and a half of battery life. Darned AT&T bloat lol

So how do we decide the most efficient charging method possible? How do we look at the Amperage of the battery and the amperage of the charger and decide what's best?
Also what's faster? Wall charging or fast/quick charging to a USB line?

This doesn't mean you battery is "on charge" for all the time... once the battery is 100%, the charge changes to something called "trickle charge". At this point charge does not happen continuous, but like a trickle to maintain the 100%.
Pull the phone out at the end of 8 hours of charge, and notice how quickly it goes to 99. Pull it like 10 mins after it says full, and it takes longer to go to 99%.

Higher amps charge battery faster... but... at the cost of capacity... At approximate 10% more charge than the battery is optimized of, it kills the battery by as much as 30% sooner. So its not really worth that. At the same time lowering the amps by 10% increases life by about 20-30%.

Yes it seems like too long for too little of a charge. Give the Samsung one a shot.
Your using a charger that at very best pumps out 1amp

It's from a HTC wall charger. I changed it to the Samsung charger that came with the phone. Will let you guys know how it goes when I go to sleep tonight.
Will the USB cable make a difference? I have a super long USB cable that I like to use instead of the short default cable that came with the phone.
I know about the 1 Amp / 2 Amp charger ratings, but unlike the original post:
I have my Motorola Xoom 10.1 plugged into the wall, and i use a USB OTG cable from the Xoom to charge my Note 2 overnight (so to only use 1 plug socket).
So i assume this is providing 1 Amp or even less to my Note 2.
I often have it charge my Note 2 from 5% or less all the way to 100% in under the 6/7 hours sleep i get.
Somehow the original posters 35% charge in 5 Hours seems very slow.
with my Samsung box set usb cable, it still takes 8 hrs to charge 100%. sometimes the red led is on but without a single percent charge. I am talking about charging with the usb connected to the laptop. if plugged in power, it takes less that 3 hrs for a full charge.
I remember my previous win7 was perfect, may be the new win8 is having some problem or not, I don't know?

My Xoom must give out some good Amperage if i can get a 100% charge in 6/7 hours then.
The "only" thing that matters is the voltage.
The included charger puts out 5V(+-5%) and 2A.
Too little voltage, and it won't charge.
Too much voltage and you will burn a fuse or the charging circuits in either the phone or the charger.
The phone chargers (no matter what brand it is) are within the limits, so don't worry.
The current (Ampere) shows how much power your charger can deliver at a given time, but the phone itself decides how much current it can take.
A standard USB-port (1.1) gives out 5V and 500mA.
I've built LED cables based on this.
USB 2.0 and higher are supposed to be able to give up to 1500mA under certain circumstances.
My motherboard has a pair of special USB-ports which can recognize cameras, phones, etc. and charge with a higher current and even without having the computer turned on.
While charging through USB-ports a full charge takes ages for me, 6 hours while sleeping will never even charge close to 100%.
On the other hand, charging though the adaptor that came with it or any other adaptor that can pump some juice is blazing fast... 3-4 hours and it's back to a 100%.
Okay, this will sound too silly but this worked for me! Encountered and suffered from the same problem..
It used to take 8 hours to get fully charged...but in time i noticed this silly and weird thing...should work though..
Before putting the phonw on charging, kill all running apps...then when you plug the charger-DO NOT TURN THE SCREEN OFF BY YOURSELF...let it sleep automatically. And it'd get charged lighting fast...it worked for me!

If i put my Note 2 on charge where its at 25% battery, in 30 mins my battery gets charged to $85%! And you should ALWAYS use the charger that comes with your phone instead of a charger made for another phone. The HTC charger is designed to charge that HTC Phones battery. Each charger is different in the sense it provides different amounts of power. The Note 2 battery is huge so the Note 2 charger is designed to push a specific amount of power to it to charge it in a reasonable time.
For e.g. If you use the iPhone 4 charger to charge an iPad, in 5 hours it will charge the iPad to approx 50%, and if you use the original charger to charge the iPad the iPad will be more than fully charged. Thats because the iPad charger is designed to accommodate the huge battery inside the iPad.
Also i read an article not too long ago that said that alot of science goes behind these smartphone / tablet chargers and how its dangerous for the charger and device / battery if you start mixing and matching chargers.
My $.02 cents!

Guys this issue is annoying me. My device is having some charging problems. I have measured the charging time for last two charges, and its taking 3 hours 40 mins for 10% to 100%, and 4 hours from 0% to 100%. Where most people are saying it takes around 3 hours, from a complete drain to full 100%.
So have any of you guys ever measured the actual time of charging? A lots of comments I see say around this or around that, or from 2 hours to 3 hours, well that's not what I need. If anyone has measured the time then please post here. I'm thinking about going to SC, but I don't wanna go there until I'm totally sure that there is a problem.
PS: I'm talking about Stock charger, (2A) plugged in AC power source. And device should be on, not off.
Btw- There should be a technical answer to this, the charging current is 2A and the battery is 3100 mAh, so how could I do the math?
Thanks in advance.

I don't know the math stuff but why don't you try calibrating the battery - worth trying !
Knowing that info is only half the truth. How the phone charges the battery and how much energy your phone uses during the charge matters too.

The time taken to charge is a pretty simple mathematical formula. But the rest of the calculation is complicated.
If you phone is on, how bright is the screen, is the display on or off, are you on wifi or network data, are you syncing email every 15 minutes or every hour, are you using the phone to send messages during charge, have you got gmail, dropbox, facebook, instagram, whatsapp, etc etc etc all doing a sync at regular intervals during the charge?
All of those things will use up some of the charge as its going in, so the charger is fighting against you.
I've been charging off usb at work and struggled to gain 20% in 8 hours because of my usage pattern.
Theoretical time for charge is about 1:30 hrs. Reality, start and ending charge should slow down (for safety), heat slow downs, plus usage of phone as spoken above I guess it could take up to 3 hrs.
It's not great to do a full charge regularly. I tend to keep mine between 40-90% for maximum life cycle of battery.
Perhaps try resetting battery stats? Try a different 2a charger?

If anyone has measured the time then please post here. I'm thinking about going to SC, but I don't wanna go there until I'm totally sure that there is a problem.
PS: I'm talking about Stock charger, (2A) plugged in AC power source. And device should be on, not off.
Btw- There should be a technical answer to this, the charging current is 2A and the battery is 3100 mAh, so how could I do the math?
Thanks in advance.

Mine takes 2.5 hrs to charge from 10% to 100% with phone on using stock wall charger and cable (when charged continuosly with no activity on phone). It charged from 1% to 96% in 2.5 hrs with phone switched off (switched it on exactly after 2.5 hrs to check). But, usually i avoid charging my phones to full 100% (also always charge it when at 10%).

Try with another note 2 charger first. The thing with these chargers is they will behave erratically when there is voltage fluctuation or if you use in a train and other cases. So go to SC and tell them its taking almost double time for me to get charged. They will replace the charger as well the cable. My cousin has the same problem with s3. He got it replaced by the SC.

Thanks Chaitanya. But the SC guys are so stupid here. First thing they do always are to take the phone in their custody and deal with it badly. Still I will ask them to replace the charger and check.
Some of us have noted that if you let the screen time out and not manually shut screen off after connecting the charger. ..The charging is faster. . If you manually shut off the screen. .. The charging is slow.... It is weird but don't know why. .it definitely is happening
handwritten from my note 2 (N7100)
Mine takes about 3 hours to charge fully from 15 %

Op: I said theoretical it will take 1:30.. Realistically it should slow down during stages due to safety reasons.
Mine took probably 3 hours the other day I ran it down, but this was combination of using 1a and 2a charger.
I think on the note 2 it doesn't ramp up power till it gets to 20-30%. Took a while to get there from 2%. If only battery widget was working on the note 2..then I could confirm.

Are you using the charger that came with Note2 ? I was using my old blackberry charger and it took for ever to charge the phone.
The output of the Note2's charger is more than twice the output of my blackberry charger.
^ Yeah, of course I am using the stock charger that came with Note 2! I'd not create this topic if I had used another charger.
Anyway, after a long week in Service Center now my phone is back, they provided me a new charging adapter (not the cable) and I was very happy because I thought everything will be smooth and like before but guess what? No improvement. It's still taking long! I just measured it for 30 mins exactly, it went from 70 to 83%, i.e 13%, where it should be 24% as stated in this thread,

Now I am really angry. I will try with another Note 2 USB cable first, if that fails, there is something wrong with the device, I guess?

I really don't think it's your device or your battery for that matter. I have a question as well (sorry to hijack...). When you were charging it for 30 mins, were you using it? Was the screen off or the phone totally turned off? I noticed one night that I had an email notification and the phone did not charge because the notification LED was on all night while I slept and it was plugged into my 1A Samsung charger from my original Note. I have yet to check if the charging disconnects itself if the LED comes on. I don't even know if the phone charges at all if the screen is on either. Can anyone confirm? I guess I'll try it out tonight! The battery last forever I got to admit, perhaps most of the time I'm slow charging it at 1A max with the original Note's charger? I guess it does the battery some good
Thanks a bunch!
No pal I am not using the device while charging (because I am testing and measuring the times, that's why I restrain myself from touching it), and it's on, not off.
Anyway, yesterday I went to a friend's home and found he has a Samsung ACE and has same USB port like Note's and I was carrying the charging adapter, so I took that Ace's cable and plugged in to my Note's adapter and let it charge for an hour, and I was amazed and happy to see that it increased 38% in 60 mins. Well this tells me that the USB cable of my Note 2 is gone to heaven.
And oh, if you charge and use the device at the same time it will charge pretty fast even then too. I can confirm this when I first got the device, always was using it and charging, and I was surprised to even then how fast it was charging.
I (and many other users) have similar problems with Galaxy S3. I've made an app that shows the actual charging current: http://forum.xda-developers.com/showthread.php?t=2076078
I'm not sure if it works on the Note 2, but it is worth a try.
Please check if your device is charging at the optimal charging current (I think it is 2000mA for the Note 2 charger, instead of 1000mA as pointed in the SGS3 thread).
To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Sony Xperia XZ Premium can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
Qnovo Adaptive Chargen very useless. This phone charge 3 hours 30 minutes.

Before saying such things, do you even have any idea why this happens? Don't post something like this like is a con when you don't know why this happens. Also you can disable it easily if you don't like it.

Yes i know "Battery Care" function. I Turned off.
I tried a lot cable and charger but i give always 3 hours 30 minutes.
Because this phone has got QNOVO Adapdive Charge technology for battery life.
But, that's why:
%1 percent to %51 charged with 2380mA
%51 percent to %60 charged with 1990mA
%60 percent to %70 charged with 1510mA
%70 percent to %75 charged with 1220mA
%75 percent to %80 charged with 1020mA
%80 percent to %83 charged with 920mA
%83 percent to %85 charged with 720mA
%85 percent to %87 charged with 620mA
%87 percent to %100 charged with 530mA
Totally full charge 3 hours 30 minutes.

3 hours 30 minutes charging time (Oneplus: 1 hours 28 minutes, Galaxy S8 1 hours 41 minutes, HTC U11 1 hours 44 minutes)
We dont need QNOVO for 2/3 months extra battery life.

If you charge it to 100% (and discharge it to 0%) every day then you will not extend your battery life for sure... If the charging time is the most important to you, get OP5 or S8 and stop moaning. And 3 hours and 30 minutes? LOL...

3:30? I got it with UCH12 and it was charged from 1% to 100% in 2:38. I only tested it once as I don't let it go under 30% and I charge it max 87-90%

Battery Care open 3.30
Closed 2.40
To be honest I'd rather wait longer for the phone to charge than damaged the battery over time. I rarely go below 50% and charge above 80%. This way the wear to the battery is minimal

I had the same results when i made a full charge with the uch 12 charger. Most people say that the 40% to 80% rule is the best for the longlivety of the battery, but i perform the 30% to 90% rule as well because it lasts me almost 2 days with a normal use.
This phone lasts me forever, so I don't care that it doesn't charge 80% in 15 minutes. I just wish it had the time to full charge listed like my old SGS6 or that it would at least have a notification somewhere that you were in fact rapidly charging (again, like Sammy phones).
Less than 3 hours to charge from 5% to 100% as you can see in the attached image
I use a aukey power charger with quick charge 3.0 and an Anker USB 3 cable

with battery care on, I also got approx. 2:45 with UC12 and also charged from 1%, I often charge from 15% and got approx. 2:35 fully charged.
Hahahaha... I bought a 3A "fast charging kit" yesterday, because I was by friends and forgot my charger. Manufacturer is "hama". It looks really nice and like it's good quality. But... Hell... 2% in 19 minutes? WTF?! Hahaha... I think this is ultra fast charging gone wrong.
You all are stupid. Turn off battery care and you will charge it for 1:15 to 1:30 h with Sony UCH12W.

Battery care is disabled since I bought my XZP ? I think it's a compatibility problem with my hama charger. The Sony charger does it's job really fast ?
I think that Sony UCH12W is the best charger for Sony XPERIA XZ Premium
My XZ premium went from 4% to 100% in 1hr30 using the standard UCH12W and UCB20 cable.
Xperia XZ Premium charging query?
Hi burakkcbyk
Are the figures you stated below specifically for the Xperia XZ Premium? I ask as I had an online chat with Sony today and they were next to useless. The advisor told me the phone actually draws 2.8a @ 5w, but this doesn't make sense when the mains charger supplied can only provide 2.7a @ 5w. Furthermore, the official Sony in-car charger can only push 2.4a @ 5w. So, with your figures below it seems to me as if the phone actually only draws 2.4a maximum anyway?
Kind regards
Dave
