I've just looked at my phone to check its battery level. I unplugged it at 7:30am this morning when I got up for work.
I've just looked in the power section and it reports:
62% (pretty good) 4h 12m 37s on battery
This is completely wrong - my phone hasn't been near a charger for the last 12 hours.
Has anyone else had this?
Yes, rebooted the phone. Didn't see that happen again

Is there a preferred battery charging regimen for the One X battery?
That is, is it better to, say, always let it drop to 15% and then recharge to 100%, or can/should I charge whenever possible, or in smaller increments?
Also, are there disadvantages to using the phone while charging (as I tend to do quite a lot )?
Thanks!
i normally let mine down to about 10% then just charge it too 100%

Right, but do you know if this is actually the way to go with the Li-Po battery or are you, like me, just winging it?
When i first got my phone i let it run down till it asked for the charger, then left it on charge over night.
I did this for the first 3 or 4 times as i found this yields the longest battery life, since then i charge every 2 days regardless what percentage is left always over night though.
Going to leave it tonight & see if it will go till tomorrow night, its been off charge since 7am on Friday morning so far & is still on 46% a total of 39 hours so far.

You get two days on a charge? Are you a wizard? Although, having just got the phone (and possessing the patience of a 5 year old), I've done a lot of start-stop charging, which I suspect isn't optimal.
I'll try to refrain from trickle charging for a while, see how much difference it makes. Thanks.
Another battery charging thread? Just plug in the damn phone! It will take care of the rest.

I have noticed that the battery does drain in strange amounts.
I have my wifi & gps on constantly, my phone went for 2 days 5 hours & i received a text at which point the phone was at 34% battery.
The phone was put back in stand by & the phone went totally flat in the next 4 hours, this i find strange as over night in stand by it only uses 1 - 2%.
There is obviously a bug in the way the phone reports its battery state, by my reasoning this must be some 10 - 15% lower than what it is reporting.
It does seem to have some difficulties reading the battery level correctly. I've noted a couple of times that it shows a significantly higher charge level (+5-7%) after a reboot. Which is hardly likely to recharge the battery. (Unless I got me one of those perpetuum mobile, in which case, yay!)
Got my rezound battery in a couple days ago and so far its not so good. Gave it a full charge out of the box and then bump charged it. Wiped battery stats and then ran it hard to drain it dead till the phone shut off. Recharged and bumped it again. It will hold at 100% for a good while during use but then drops drastically. Sitting doing nothing it dropped to 60% in about 2 hours. Then listening to music it went into around 20% in 45 minutes. Charged it overnight and today sitting doing nothing it was down to 30% in about 4 hours. Put it back on the charger now its only charging to 88% and stops. Am I doing something wrong here or is my battery a dud.
Update
after the charge to 88% I have used the crap out of my phone tonight and more over the last 4 hours. Surfing on WiFi, music, and running repeated benchmarks. The battery had sit for several hours off charge and dropped from 88 to 52% while sitting unused. Dropped from 52 to 35% over a few hours of music and 4g web browsing while driving my wife around shopping. After I got home and started using it stayed at 35% for over 2 hours of use and has dropped down from 35 to 28% in the last hour or so of continuous use. Seems like its holding a good charge, but just not reporting battery stats correctly.

I have had the Rezound battery for several months and at first it was reporting the battery accurately, a longer usage time, and no complaints. I would go down to about 5% and then I would charge it.
The last few months have been erratic. The battery could show anywhere from 15% to 25% then just shut off completely. This has become very frustrating and unreliable once I get under 30. I downloaded a battery calibration app that has proven to be worthless.
I was on vacation last week and found out something interesting. If I charge the battery to 100% then take it off for about 5 minutes and reboot the phone it will show that it is charged to somewhere between 79% and 84%. I can let it charge again to 100% and get a full charge that time. I tried several times doing battery calibration and it seems to make no difference. I think the default stats file is limiting the charge to the stock battery capacity somehow. I know the stats file gets written on boot and I found a post on here somewhere about HTC releasing an update for their extended battery after its release due to it not charging completely. I wonder if the rezound battery and all other extended batteries that aren't the capacity of the two official ones could perform better if they had modified stats files. Without the reboot and additional charge I am averaging 16 hours roughly per charge. With the additional charge I have gotten over 30 hours on one charge and get at least 23 hours. Last full charge was 27 hours 38 min and still had 16% charge.

Finally broke down and got one yesterday from Big Red. So far, on initial charge (off wall charger), I'm @ 38%, 15 hrs, moderate use. For me, it's an improvement over the stock battery. FWIW, once I popped in the rezound battery, I wiped battery stats in CMW....

My rezound battery was doing great until the first weekend when I had to switch it with the stock thunderbolt one on the fly. Since then they seem to perform, at best, the same - but usually it seems like the rezound one lasts even shorter than the original.
So i got the Battery last week. and did the initial 12 hour charge and then some. and battery worked great (lasted 3 days). then i got it down to 1% and then charged it to about 60 before i unplugged it. since then every night that i've put it to charge it charges normally for the first little bit and then has spiked where it goes to 75% then up to 100% then back down. It displays it as 100% but when i unplug it, it goes back down to 75%.
at this point the battery was plugged in for more than 24 hours and its still at 75%. when it is unplugged the battery performance is nowhere near what it was in the beginning or even remotely close.
anyone else had similar problems or am i doing something wrong ?
ps. i did battery reset.

Something odd happened to me today.
I went to sleep listening to an audiobook, the G3 was at 100% battery.
When I woke up ~8 hours later the battery was at 99%, it was plaing audio the whole time.
Obviously a display bug, when I went to see battery status it said 648 hours left.
So I restarted the G3 and nothing changed, the battery is now at a lower % but it behaves as though nothing happened.
Please tell me the battery micro-controller isn't screwed and doesn't now report 70% as the new 100%.

I had something like this as well, but it went down a tick eventually. i was browsing reddit for 30 minutes at 100%, then it went to 99%. Not sure if it's just amazing battery life, or somethin'gs up.

I would drain it to 0% and then charge it to 100% without unplugging it. That should recalibrate the battery
From 100% > 99% seems to take an age. But soon as it hits 99% it does drain considerably faster.
If you check you batter after you have charged it, it always says Estimated time remaining and collecting battery info... please wait.. until it drops to 100%
I have same issue but its not bother me much. Whats bother me is that some times when I go to sleep and live phone at 60% I wake up tomorow and its 60% and sometimes drops like 3 or 5%...any one have that issue?

Well, it's hard to say but maybe it wasn't a problem after all.
Seems like the battery % is highly inaccurate at top levels. 100->99 takes much longer than 99->98.
I took the advice of someone in this thread and fully discharged the battery and then fully charged it.
It did take a while though, 6-7 hours from <1% to 100%. Using a computer USB port for charging.
Is charging faster with the provided power USB adapter? Or with wireless charging?

Yes and yes, if you use an apropiate AC Adaptor. Pc is usually charging at 500 mA and an Ac Adaptor up to 2 Amps. So you charge 4 times quicker in theory.

my galaxy tab pro 8.4 stops charging at 96%....
i always charge it from 10 - 15% to 100% by switching of the device...from past week it always stops at 96 and when i switch it on it goes to 100 in a cou[le of minutes...what i s to be done ..i calibrated also..no change..
Yep, you have custom rom? that's usually what happens.
I have the slim rom and mine is like that, I just unplug and then plug back in does the trick

Custom rom has nothing to do with it. I am running the stock version, and my battery won't charge up more than 64% right now. It seems the problem starts with 96/94% but gets progressively worse. Sometimes it will fix it self for a short time when I replug, but right now even that doesn't work for me.
I checked last night, and I believe the kernel just thinks the battery is nearing it's 100% state. This was a screenshot I took that shows that the battery isn't charging at full power. The closer I got to 64%, the slower the charge went:

Have you tried just using the tablet when it was "fully" charged to 64%? I see three possibilities and I would be curious to know was the case:
1) Your battery is only charging to 64% and when you start using it, it will decrease at a normal rate and you'll get 1/3 less time out of the charge.
2) Your battery is showing 64% for all charges >= 64%. So, it could be at 100% charged and will stay at 64% until you've used up 36% of your battery.
3) It is scaling wrong so that 64% == 100% and the battery percentage will decrease as you use the tablet, but it will decrease 1/3 slower than it used to (aka the time from 100% to 0% when you first bought it would be the same as your time now from 64% to 0%).
Any idea which of those three is actually happening?

Definitely the first one. Right now I am at about 35% and have 2.5-3 hours screen time since the 64% (can't check for a definitive screentime as the indicator doesn't reset unless you charge to 100%). So that would translate to the about 7.5-8 hours I get when I do have a full charge.
I also checked once before when I had this issue by letting my battery completely discharge and then start up my tablet again and I had 1% left, so it was pretty much completely drained. I'll probably charge it again tonight and I expect I will have an even lower full battery percentage.
Try using a different 2amp charger and/or different cable

The only real fix for this opening the back up and unplugging the battery. When you plug it back in you won't see the problem again. Not sure why.... But that's how I fixed mine. Been good for two months now.

Also tried that already. Still only charges up to a lower percentage. Only thing I haven't tried is unplugging the entire battery.
It charged up to 100% for some reason last night. The only thing that is really weird that it charged 1% every five minutes from like 85-95% and then suddenly in the last 5 minutes it instantly charged from 95 to 100%. The whole battery thing is just really weird.
