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.
I was using HTC's charger.

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.
I've had my S3 for a few months now and I've noticed that I get different battery life depending on my charging habits with nearly identical use.
If I charge it overnight (thus, it remains on charge fully charged for a few hours) I get about 8 hours of general use.
If I charge it during the day and monitor it and take if off charge soon after it is fully charged (thus, it does not remain on charge fully charged) I can get about 1 to 2 days of general use.
That's a HUGE difference just from charging habits. Anyone else observe the same thing?

It seems to be the exact same with me. I always charge my phone over night and it will drop must faster than if I partially charge it or take it off when its done. I would like to know if anyone has a way to fix this.
Same here. It really annoys me, because I don't really want to wake up in the middle of the night to unplug my phone.

I think that's a lithium ion battery thing in general, and not just an S3 thing. I don't know the exact guidelines for charging a lithium ion battery because there is a lot of conflicting information passed on through word of mouth, but I think - as I prepare to pass on my own word off mouth theory- I think you're supposed to charge your battery before it gets less than like 10 percent discharged, and you're not supposed to let it overcharge. There's something about how lithium ion batteries have a memory to them and if you charge them improperly, you risk slowly killing your battery over time.
I realize now that you may already know all that but are just asking why overcharging your battery specifically leads to less battery life that day, but I don't know that and I already typed all that carp out, so it's staying

Phone charges to 100% then doesn't charge. Even if it says 100 while plugged in it could be down to 90. I have no idea why this is cutting a day off your usage time, but that is why it is shorter than if you unplug it. Could be that you use it more during the day and you are getting longer usage times since it is charging while using and unplugged at night while it is barely using 1 or 2 percent of the battery for 8 hours.
I put mine on charge at night before I go to bed, and then disconnect when I wake up the next day. It comes the whole day until same time in the night to put to charge. I normally get like 3+ hours display (on auto brightness, and full sync) with about 30% battery left.
Once battery is charged to 100, even if its connected to charger, there would be only trickle charge, and not regular charge to the battery. But it shouldn't make a significant amount of difference between taking off immediately or later in the morning.
I just leave it on charge overnight. There are sensors in it to prevent overcharge. What hurts lithium batteries is letting the battery drain to 0%.

Yesterday I used fast charge to charge one of two batteries to 100%, and charge other battery with wall charge.
Today, basically same usage, read electric book , wall charger charged battery last about 4 or 5 hours, then I replace it with the battery charged by fast charge, suddenly.... 25% drain after 30 minutes...
So I start to think that fast charge isn't really make battery up to 1800 mAh or what?
Because it's kinda ridiculous that 30 minutes drain 25% battery with only reading electric book, I suspect even play 3d game or 3G network browsing could drain that kind much juices in 30 minutes ...
I don't think it relates to ROM or something like that, because when I use these 2 batteries in same environment, didn't do anything, except shutdown, replace battery and boot...
Any theory?

All fast charge does is allow a full amp from a USB cable (normally limited to half an amp from USB). The battery doesn't care if that amp comes from a USB cable or a wall charger, so no, it doesn't die faster based on a charging method.
But still curious that why my wall charger charged battery lasts 4,5 hours but fast charge charged battery drain 25% in 30 minutes which would only last like 2 hours in same usage....

Actually duplicating usage is nearly impossible. There could have been instances of lower signal, which chews on battery. There could have been a rogue background process that was chewing on the battery. There could be one of a thousand things that changed how your phone went through your battery.
The only argument for fast charge being the culprit would be an argument of a full amp vs a half amp charge. Some might argue that the half amp slower charge could lead to a better tuned battery, but I'm no electrical engineer, so I don't know if there's logic for or against that argument. However, if you're using a full amp wall charger, your battery won't find a difference between the amp from the wall or the amp from USB.
That's true, slow charge improves in fact battry drainage. It is true fir my GNex and the 3 other Android phones I got before. I don't use my wall charger anymore.

Impossible yes, I know, but still, it shouldn't be that much different as first battery lasts 4,5 hours and second only about 2 hours....
And I didn't do anything like change setting, install new app or kill background process, as i said before, it might have some different, but shouldn't be that much

I had a One X that took forever to charge, based on its battery consumption. I went back to an Iphone which charged quicker and didnt use as much battery when playing music. Can someone tell me if the Optimus G charges quick? How fast does it take (wall, and computer) - I charge my components while riding a bike, so the less pedaling, the better
I don't have an exact amount of time nailed down (never timed it or anything) but I find with the wall charger it does recharge it pretty fast.
On usb however its pretty slow.. probably more than 4 hours from drained I'd imagine with USB.

I use a 1200 mA current charger and it will take about 2 hours (or few minutes more) to charge from 5% to 100%.
It's fast enough for me.
About battery drain, I have to say it'a all about your usage habbit.
After a hard reset I powered on E975 and let it standby for 45 hours.
The battery drained from 80% to 69%.
NO SIM card inserted.
GPS and Android Beam(NFC) enabled (but not active).
BUT, when you use it with screen on, the battery drains quickly.
Hope it's helpful.
This is the only electronic device I have ever owned that seems to charge slower than it discharges. I mean it takes FOREVER.
Is this a bug, a too weak charger or something else? I expected battery life to not be so great with this amazing screen but didn't expect the very slow charging. Any ideas? Thanks in advance.
When I first opened mine it was at 60%. I charged it while setting it up & play with it. It took about 3 hours to 100%. So charging is still faster than discharging but of course it all depends on how you use it. One thing I did notice is that battery drains very little when it's in sleep mode, which is great.
Looks like Samsung charger is slow. I just tried using my wife's Nook HD+ charger which also has 2.0A output and it went from 65% to 100% in 1 hour 20 minutes. I have a 10.5.
My 8.4 took just over a couple of hours to charge from 0% last night. Tablet was switched off though. Haven't tried it powered on yet.

It seems to be improving a bit now that it has a few full cycles under its belt. Regardless the Samsung charger charges my Note 3 very quickly. Perhaps turning it off completely during recharge is the answer.
Big difference in chargers, been using my LG GPad charger and it's been good about 25% an hour, last night I put it on a cheaper charger in my bedroom, was at 15% and 8 hours later was at 80%. Definitely want to use 2 amp chargers

Well the Samsung charger is 2 amps. I have noticed charging seems much quicker with the table completely off.
Charged my tab up whilst switched on last night. Was at 9% and about 2 and half hours to reach 100%. Seems good to me.
