How long did it take on you guys' devices to fully charge before starting it for the first time? Im asking because I'm getting mine delivered this wednesday at work at around 2PM, and I leave at 5PM. Will it be fully charged in three hours? i dont want to interrupt it the very fist time already...
I did mine yesterday in around 4 hours, it was power off so I didn't know when it exactly fully charged, when the time I saw the green LED light(i guess it's 90%) I still let it charge for an hour or so i think.
But I guess this thing doesn't matter anymore on lithium ion and lithium polymer(htc one x) batteries, it was important last time during nickel cadmium days.

Green light is full.
I used mine instantly after purchase, it only had about 15-20% left so I started charging it at 8%, took a few hours.. quite long.. but I guess that process will speed up after a while, like my other phone.

My one x is currently charging and has been for roughly three quarters of an hour. The documentation it came with said that you have to charge it for at least 14 hours! That sounds ridiculous to me.
Did you guys have any issues with the battery after charging it for 3 or 4 hours?

14?? due i just charged till it became full ... even that was a little more than 3 hours .. this is official htc docs?? u sure ??
I'd say you just let it charge a night (+/- 8 hours) before you start using it. That's the most optimal way to charge it the first time.
But I couldn't wait so I just started charging the device from the start but also used it (which is imo still better then not charging).
A lot of people also say you shouldn't let the battery drop below 10 % on purpose, better just charge it every night! That's what I did with my HTC Desire (AOSP rom) and one full charge lasted 2 days of average use after 1.5 years. Hope to get the same result with this phone.
I left it for about 5 hours until it was fully green. First days usage today and it's been alright. I'd post a screenshot but xda app won't let me upload png. About 9 hours moderate use and at 10% now

If I had enough patience then I would definitely leave it to charge for 8 hours. I'll crack the moment the led turns green, I know it.
I've heard that 40% is the optimum level of charge for keeping the battery healthy

Yes that can very well be, that's the % I normally had left on the Desire after a day (with more then average use). I charged it every night and the battery was still awesome at the end. Considering the One X has the same battery technology I'm going to do the exact same thing.
Keep in mind that a green led doesn't mean it is fully charged (at least not the first time). The led turns green when the software says the battery is full, but the issue is that the battery never had been full when you charge it the first time. So that first green led is quite useless, the software isn't optimized yet. Rather watch the clock!

The thing that worries me about charging it every night is that it remains plugged in for several hours after its reached full battery. There isn't much you can really do about that though.
Yeah, I was told that the first couple of charges were used to calibrate the battery monitor and you have to make sure that its fully charged before you unplug. In fact, my Nexus s (soon to be 'my old nexus s') only ever charged up to '97%' according to the various battery widgets I used. This may have been to do with me not charging it properly the first time.
What I want to know is can I turn it on and let it continue to charge? That way I can set it up and install my apps etc (and, of course, have a play) so I don't go insane waiting without damaging the battery life.
There we go.
Not bad for first day I suppose.

No issues with battery here.
My advice would be to completely drain the battery.
Keep powering the device on until there is absolutely no juice left.
Then remove the battery, re-insert and leave to fully charge without powering the device on.
See if that resolves your issues.
Battery life on mine is excellent after a weeks useage, no complaints here.

Have you tried this yourself? Because, I wouldn't probably be comfortable draining the battery quite as empty as suggested by this method. The Li-Ion batteries need some charge to be left in them even when they are "completely" discharged, or else they are damaged (it may actually stop accepting charge, so recharging becomes impossible).
I think it should be enough to just leave the device on for as long time as possible - until the device finally shuts itself down. Then do a full recharge and you should be ready to go.
Of course if you've done this yourself and can confirm the battery still accepts charge after such procedure, then no serious damage has presumably been done. Wouldn't go quite this far myself, though.
Cheers
I can't say for certain about the TP2 battery but most Li-Ion batteries will have a tiny protection circuit in them to prevent over charging and over discharging. Becasue of the potentially explosive nature of Li-Ion batteries I would be very suprised if the TP2 battery didn't have any protection.
Yes that's true. And TP2 most certainly has this chip. However, I'm not 100 % sure if that chip can protect the battery against this kind of "abuse". It probably can, but I wouldn't like to be the first in line to check if it can or not...
I agree with what you all say, and yes I'm pretty sure that the protection circuits are there. I haven't tried it on my Rhodium, but did on my Raphael after lending to a colleague who was incapable of maintaining. Charge would hold for around three to four hours of useage, pretty damn useless after a week of abuse.
I totally disharged as much as I could, then left overnight with the device powered off and since then the battery useage has been as norm.
I know were not supposed to be affected by memory issues, but go figure...........

been in touch with HTC uk
they have told me to do the following
from flat
charge for 10mins then use the phone do this 3 times each time making it dead before recharging
thay say this will condition the battery
does this sound right?
So it's already been established that after the EVO charges fully to 100% it then stops receiving a charge and runs off the battery before charge cycling again. All the while displaying 100%.
Has any effort been put into changing the way this operates? Seems like it'd be nice to leave the phone on a charger and when you take it off, it would actually be at 100% and not at some arbitrary percentage between 90% and 100%.
It's better for the battery life.It's really good option if you ask me.
Sent from my HTC Magic using XDA App
You mean make it so that the battery's status bar shows a realistic value once it stops taking a charge, even though it's still plugged in, right? Not actually changing the way it takes a charge. I'd be interested in seeing that happen.
Is that why when you unplug it, the first 5% or so disappear within minutes?

Yup. This is why when you charge overnight the battery plummets right after.

Don't leave it plugged it after it reaches 100%. Problem solved.

Valid point. Lol
There are some people who don't want to wake up in the middle of the night to unplug their phone. Like me.
annoying, but just unplug your phone when you do wake and plug it back in after about 10 seconds. let it finish fully charging while you get ready.
it's better for the battery though, case closed. Lenovo has been doing somehting similar w/ their laptops for years. It never charges the battery past like 97%, and when it does reach the top it stops charging until it falls below like 92 then recharges. HTC needs to loook out for the battery they already have enough flak from all of us for the last few years w/ every touch device they have had. We want more life, and they are giving it to us, just wish they could figure something out like lenovo, let it go down to mayeb 94 then charge up again perhaps.
it really isn't true, mine dumps 10% or so off the charger regardless of if it has been on the charger all night or 2 seconds after it turns green.
So I've done the:
1 charge to green
2 unplug
3 turn off
4 charge while turned off.....to green again.
And here are my honest results.
Boom........phone has 20% left after 16.5 hrs of moderate use (calling time total 1 hrs talk total, surf /post 1 hour total, load up 5 apps from the market, listen to audio clips on the speaker phone for almost an hour straight, podcast this morning for 30 min...and other randomness)
And still have 20% left. Going since 6:30 a to 10:30 p...........approximately 16 hrs equals 80% so about 3.2 hrs left to use before dead.
THIS EQUALS APPROX 19.2 HOURS OF MODERATE USE BEFORE RECHARGE NEEDED.
eat it Apple 4G . You can't even reliablly make calls let alone last that long without charging. My 3g never lasted that long. You still need a wall Apple we are truly mobile. If I was on the road I could (don't need to just yet) swap out for another battery.
I'm loving xda for all their brains helping me get the most out of this phone. Thanks to all.
Sent from my HTC EVO 4G using the XDA App.
The point here is that we shouldn't have to do the "charger circle jerk" to have 100% battery. I should be able to unplug it and have a full battery. Not 90%. I might need that 10% later on today, its accomplishing nothing sitting on my nightstand.
If the battery is toast after a year instead of a year and half, i don't care. I want a fully battery, not an almost full battery.

My phone used to do this, even after i followed all the little tips and tricks of playing hide and go seek with the charging cable and my phone.
Know how i solved it?
Bought one of those $10 Ebay 2 1500mAh TP2 Battery And Wall Charger bundles, now i dont use the OEM charger at all, the cable turned into a permanent USB cable on my comp and never sees the actual HTC charging unit it plugs into for AC power. I have 3 batteries and i rotate them in that little wall charger which actually charges them to 100%. Its also proven because if you take one of the batteries, put them in the phone and charge them until the green light comes on, supposedly to "100%" and then take the actual battery out and put it in the ebay wall charger, it will still charge for another 15-25 minutes. Charging it in the phone, as soon as i unplug, it almost instantly always drops to 90%... charging with the ebay wall charger, it will stay at 100% for a while before it falls off.
Below is the link to my thread which contains linkage, pics and info about the ebay bundle, others also claim the same issues and fixes in my thread. I mean for $10 bucks, does it really matter if it works for you or not? Its worth the shot and for me, it was a great investment.
Best of luck.

Oh right. So its okay to leave the phone on charge overnight. I think i'll just do that then and every month just drain battery and recharge fully !
I actually don't plug my phone into the charger. I bought some after-market batteries that are the same as the stock battery. I used to have 2 spares, but one was faulty, so I'm down to my main battery and the spare. I leave a battery on the charger until I need it, then stick the other one in the charger. I'd say they stay on the charger for up to 24 hours.

So you take each battery out of the Xperia Play and charge them ?
Yup. Once you take the battery out, wait about 30 seconds before putting it in so the battery usage gets wiped. Once you put the other battery in, boot up and you're good to go.
Depending on my usage, I usually just charge it over night, leaving it plugged in from when I go to bed, normally around midnight, to when I get up again at 7ish. I've never had any problems doing this, I am however a VERY high usage person, so a lot of the time I have to give it a top up in the middle of the day, before I go to work.
I usually charge up to 100% right before I go to bed and unplug it and reboot it. I've still got 99~100% in the morning.

I charge 1-2 times a day. Basically every night before bed I plug it in and it stays for about 6-7 hours, But the bad cell signal at work eats through my battery if I do a lot of texting or anything so by around 4 pm sometimes I plug in for an hour and top up (I'm usually around 25% at that point), or sometimes when I get home but know I'll be headed out I plug in for 1/2 hour or 45 min to get it up around 70-80% or so and I'm good till I get home, even if I play games and stuff or whatever else.

Hi Guys, first full charge is over, battery seems ok to me, as good as my Desire at least...
for the initial charge I pulled the phone out of the box and let it charge to green, then turned it on for an hour while charging and had a play...switched off and left till the morning so...10 hours or so.
Today it was used for 11 hours from 100% to 2% with 67% screen time (3h20m)...
Just put it back on charge and I'm not sure what to do this time round to maximize my batteries potential!!! lol
Shall I charge until green or another all nighter? I've read that these early charges are crucial in the life of a new One X

I've never been convinced by this charge/discharge cycle. Lithium batteries don't like to be fully depleted, top up charges are their preferred usage pattern.
The full cycle days left with NiCad! The batteries have changed my friends, it's about time the advice did, too.
Most of the advice I hear from experts is that heat, overcharging and deep cycling is what kills Lithium based rechargeables, so if you know you will have access to a charger, keep the phone between 30-80% charged with regular top ups and don't leave it on your dashboard in the sun.
I would warmly suggest you deplete your battery fully for the first 10 times doing whatever and charge the phone while it's off. It does wonders to my X. Started off with under 3 hrs of screen time to over 4 hrs in 10 charges.

Just because your battery life got better, and you did deep discharges, doesn't mean one caused the other. There is a difference between a causal effect and correlation. But whatever. I'll believe it when I find a reputable study.

So many people here have their own opinions on batteries.
CHARGE IT HOW YOU SEE FIT. CHARGE WHEN YOU NEED TO.
There we go. All of this fuss over batteries when most of the time any effect seen is placebo.
I got my phone on the 5th and I'm currently on charge number....74...I think?
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!

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.

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!)
