[Q] Charge times

How long does it take to fully charge your One-X?
Mine is already charging 3.5h to get from 40%to 80%....
Using the default charger, and not using the device.
Isn't that a bit to long?? My HD2 was completely charged in 2h..

I am no expert, so don't hold me on this one, but I believe your device charge should speed up due to firmware updates and also once the battery has been 'worn' in - just stuff I have seen about.

Can anyone else provide me their charge times? How long it takes to charge from A to B?
Pls mention with wall outlet or USB.

I've noticed this as well. My Arc charges in like 2-3h to full. the One X takes about 2 hours to get to about 60% from 30% (using USB).
edit: wall charging takes just as long.

Can't be normal, right? 2h from 30% to 60%...

i think its to do with the type of battery they are using to be fair

Interesting reading about lithium based batteries
this is a quote from batteryuniversity dot com
Simple Guidelines for Charging Lithium-based Batteries
• A portable device should be turned off while charging. This allows the battery to reach the threshold voltage unhindered and reflects the correct saturation current responsible to terminate the charge. A parasitic load confuses the charger.
• Charge at a moderate temperature. Do not charge below freezing.
• Lithium-ion does not need to be fully charged; a partial charge is better.
• Chargers use different methods for “ready” indication. The light signal may not always indicate a full charge.
• Discontinue using charger and/or battery if the battery gets excessively warm.
• Before prolonged storage, apply some charge to bring the pack to about half charge.
• Over-discharged batteries can be “boosted” to life again. Discard pack if the voltage does not rise to a normal level within a minute while on boost.

And I also read that charge time should be almost 3h for a full charge(i suppose this is when device turned off). You could get about 70% charge in about an hour if I remember correctly.

Hmm not gonna turn off the phone for every charge tbh...

While charging and using the phone it takes around 5 hours to get from 5% to 14% when not using but charging takes around 3-5 hours to charge from 25% to 100%

My second charge, from 0% to 100%, with device shut down took 3.5 hours to show the green led... quite a long time since I was using the wall-charger... I hope it will improve with the fw update and after the battery has been "initialized"

Today I began charging my HOX at 1:44 (1%) and it finally reached 100% at 4:59.

same here, about 3h from shutdown with 0% to seeing green LED
using wall charger

Took me three hours with original HTC wall charger and original HTC cable (no extension) to charge from 4% to 100%. Terribly slow!

EDIT 1 : Apparently BWM doesn't show accurate power draw while idle on the One X for now, so my post has become totally irrelevant
I always install Battery Monitor Widget on all my Android devices and monitor charge and discharge constantly.
On my Desire Z, if it's below 70%+ I get a charge rate of about 750mAh from wall socket.
But on my One X, with the same charger (both are rated for 1amp, and both HTC), my charge rate drops to 450+ at 60% battery life.
It's probably a software issue, but charging the One X does take noticeably longer.

I don't think it is a software issue, as the battery pack is larger than before. Also when you are active the phone itself draws large amount of current and it definitely slow down your charge rate.

When your phone is idle with screen of, it shouldn't drain large amounts of power while charging. Can't imagine that has a huge influence on charge times tbh.
And for capacity, my HD2 was charged in about 2H for a 1200Ah battery, this 1800Ah One-X batt should be full in like 3h... not 5 or 6h...

The official wall charger took 2.5 hours to fully recharge the One X

Ok after an amount of charges, it now takes only 2.5h - 3h anymore for a complete recharge.
Official wall charger.

Did a charge on mine this morning from dead, took 2.5 hours to get to about 90%, left it for another hour but it didn't go up the last 10% stayed on 90 even after the extra hour. Off the wall

I'm thinking the same... I don't mind turning it off on a night for the first 2/3 charges but personally this is my only phone (don't have a house phone) so will be keeping it on through the night in case someone needs me in an emergency etc...
Was interesting to read that batteries prefer a partial charge and do not need to be fully charged; which is good actually as mines got around 18% left and I'm about to stick it on charge for the next 8 hours.

HTC one x time for full battery charge

Hi
Please post the time it takes for you to charge the phone from 0 to 100 when it is not being used and is on standby also the mention the update you have
my phone takes 2 hours with 1.28 update

That is a good time. With my New one i need also 2h. With the old one x i needed more than 6h

3h

The first charge was about 6h!! (Wallcharger , not USB)
I don't know how it is now. I plug the phone to the wallcharger in the evening and unplug it at the next morning

That's what I do as well but I don't think its the best way to charge the phone as sometimes I wake up in the middle if the night and the phone is close to exploding from the heat it generates while charging.
But as how fast it charges, I think around 2 hours for me too. USB takes a little longer, I'd say about 5-6 hours.

Your phone is overheating from charging? Something wrong. Mines very cool, basically like its turned off or idle.
Takes a while to charge fully though

Actually i think it's ok if it gets a bit warm when charging BUT it should cool all the way down when getting to fully charged.

I always plug mine in overnight... I wish I could specify a slow charge to prolong battery life. No idea how long it takes to charge.

There's no need for it. The charger stops at 100% and goes into battery mode until 95%, then starts charging again. It never approaches overcharging at any point. This is also why sometimes when you unplug your phone, it drops a few percent almost immediately, cos 100% battery was already achieved some time ago, and has been on battery the last few %

Mine takes more than 4hours .

I think you are right. It does happen to me sometimes when the battery is showing 100% and once unplugged and used for a few minutes it drops pretty quickly.

hehe i know i orginally said that i was getting 2 hours(this was the first charge cycle of the phone )
but now it takes me 3 hours for a full charge this is after the 1.28 update

going to add here, go to settings and power and check the status if it says (charging - USB) then it will charge slow for me it's 20% an hour from a USB. I also have a charger cable (has plugs for iStuff, micro USB/ mini USB and that tiny one for Nokia) and when that it plugged in it says (charging - AC) and its a lot faster.

2.5-3 hours max
charger = 5v 1a

2.5 hours here

Thanks for the thread. It also takes mine just under 3 hours from completely dead and I was thinking that was on the long side. (My Atrix 4G used to take 2 hours.)
HTC One X/AT&T

Charge time from 5% is about 3h

Hello,
i own an htc one x and the charge time are usually around 3-4.5 hours. now granted many say their average charge time for this phone is about the same. but what bugs me is that i charge my phone with a 5v+/- 1 amp charger in a 110v 50hz socket.
i have an app that measures battery usage, charge times and the amount of mAh being used or stored @ a given time interval. now when i charge the phone through the 110v socket i get 386 mAh the max from the socket. where as at my school we use 220v sockets (i have both connectors for my phone) and i get easily 895 mAh reducing charge time to just over 2 hours. so my question is.
the specification on both chargers is:
+/- 5v 1amp
so even if there is a difference in sockets both still list 1amp. so why do i only get under 400(386)mAh at home and just under 900(895)mAh at school?
btw. noob. if im in the wrong section plz redirect me. only board that looks close to what i need

Long charging duration. What should I do? Confused! Please advice.

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?

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

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,
http://forum.xda-developers.com/showpost.php?p=33585646&postcount=31
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).

[Q] Painfully Slow Charging

Hi
I've got a brand new htc M8 and enjoying it immensely, but there's one thing that's worrying me. My first three or four charges were very quick--an hour or so from 60-65% but over the last few days charging has become an ordeal. I've read numerous forums and tried a number of techniques, most recently discharging to 10% then recharging (which took nearly 9 hours). I went out this morning and returned with 85% remaining. Plugged it in and Dashclock forecast three hours and twenty minutes to regain that 15%.
I'm using the charger provided, but have tried a number of others as well.Any other ideas out there?

Do you have fast boot enabled?
If so disable that, then power off the phone for a few minutes then power it back on and try to charge.
My neighbor had fastboot enabled on his and performance and battery life always sucked.. after disabling that he saw a lot better results.
Is your phone being used while charging? Is it getting hot while charging?

No its not. Especially when your using the phone and its on 5% plugged in. Takes forever to reach 6%.

I'm having literally no issues with charging from dead to 25% in about 15 minutes. 2 hours to 100% im very happy with the speed of charging and this is using my m8 charger as the m9 one is still sealed in box.

I've been using the GS4 charger, with a high output cable. The Samsung charger is 1.5A where the HTC m8/m9 charger is 1.0A

the supplied charger is definitely giving 1.5 amps to mine. charges up pretty quick. with a quickcharge 2.0 charger it's crazy fast to charge.
One thing to note is it will take a faster charge the lower the battery level is, which means more heat. if you're also gaming with it, you could be bumping against the battery charging cutoff temperature. I only ever saw this happen on my Tegra HOX+. IIRC HTC has the notification LED blink in alternating green and orange/red when this happens. I'm guessing you would have mentioned temperature in the OP if this was the case, but I figured I'd bring it up.

Just spread your arm, pick whether HTC M8 or M9 charger, and read upon it.. 8)
Both M8 and M9 chargers are - 1.5 Ampere.. furthermore both handhelds are charging fast - otherwise if the cable is a problem..

Sorry, meant it was 1.5a for HTC and 2.0a for the Samsung one. Didn't have them on hand to check.

iPhone 5 battery is 1,440 mAh... M9 battery is 2,840 mAh. 50% charge of Iphone battery doesn't equal 50% charge of M9 battery, in terms of charge time.
I believe the rate of charging to decrease while you use it to prevent the phone from overheating. (My M8 does this as well)
My stock charger is fast, and my quick charge 2.0 is crazy fast.

Yup i got the same issue gonna take me 6-11hrs to charge and its very slow charging

I had a similar problem to OP. The second night I had my phone I plugged it in at 11 pm with about 5% battery left and went to bed. At 5:15 the next morning (6 hours later) it was only at 85%. I can't tell if there's still a problem or I just think there is because I'm paranoid about it now. I haven't run my battery down that low since, and looking at the charge current with Ampere seems somewhat inconclusive. I may have to run it down and then keep an eye on it while charging to see what's going on.

Something IS wrong with SOME M9 phones (I think)
I have one of the "bad" ones. Mine takes hours and hours to charge, whether on the cable and plug that came in the box, or on any others that I have around - some I know are 2 Amps. I think there is something seriously wrong with some of these phones, based on what I am reading in this thread, and on my own example. I have had my M9 for just a few days.

I'd like to post a follow up to this thread after having the phone for a couple of weeks now.
I've had several occurrences where my phone didn't fully charge overnight. The worst was a few days ago, I plugged it in at 5% and the next morning (6-8 hours) it was at 1%, it actually lost charge. I noticed before unplugging it so I looked at the history in Battery Widget Reborn and it showed the battery level just slowly dropped from 5% to 1% without any jumps or dips. The battery icon at the top of the screen showed it was charging but it died at that point so I didn't get a chance to open Ampere.
I think it's the charger (and/or the cable) that came with the phone. I've tried several other chargers that have all worked reliably:
- The QuickCharge 2.0 charger that came with my wife's S6 charges my phone really fast.
- I have a Kmashi external battery that also seems to charge it relatively quickly.
- Two older chargers that are several years old (both rated 5 volts at 0.7 amps) charge it from around 30% to full in 3-5 hours.
At first I thought it might have been a wakelock problem, but the battery has been dropping so slowly when the phone is just sitting in my pocket that I'm confident now that it's not wakelocks. I don't know if HTC is likely to send a replacement, but I'm going to stop into the Verizon store that I got the phone from to see if they'll replace it.

My phone is also odd when charging.
Half of the time it takes 6 hours or more to charge. If I look at GSAM battery monitor it shows a charge current of around 350mA. If I then unplug the charger and reconnect after 15 seconds I get over 1300mA charging current, most of the time. (It takes GSAM a while to show an accurate reading). Occasionally it will take a few tries to get it right. Once I get a good reading over 1300mA the phone will charge in 1.5 hours like it should.
Something very buggy about this phone's charging circuit. I get the same behaviour with all chargers and cables, even my battery bank.

Anyone else notice that with the supplied charger charging ins't what it should be. My iPhone 5 charged almost twice as fast as this phone. I find it kind of annoying. I did order one of these chargers hoping that solves the issue.

I use a 2A tablet charger from my hp touchpad. Charges from dead to 100% in 45 minutes.
