This might cross over into the accessories sub forum, but with the dock pin connecters on the back should be expect a case with a built in battery, or could we construct one easily considering existing devices with these pin connectors
[HTC One X] aslan93:
Someone benchmarked the us s4 processor version and the results are pretty amazing I can't give a link now just google it , and the guy who posted the results also said the battery life was pretty good) the s4 processor is really power efficient although the American version has LTE so they should be similar (tegra and s4) system optimization played a big role here as well I think we are going to be pleasently surprised with the one x battery life :)

Reviewers avoiding battery life

When looking at the reviews for the One X thus to date, why do they keep going on about the bloody camera and not even mentioning the battery life.

Getting annoyed i want to know if the battery will last a day of heavy use. I just brought a 2450MaH battery for my HTC Desire and love how long it lasts and dont want to give it up for something that wont last as long....

Hmm ill just have to wait and see
[HTC One X] Chartist:
You can test a camera immediately. You have to have used the phone for a few days before you can comment on the battery.
[HTC One X] lukesky:
Exactly! And batt life, unlike the cam, is totally subjective. So what if it can last a full day for 1 reviewer? That'll doesn't mean it'll last 1 full day for everyone else. Everyone's usage, network conditions & apps installed are totally different and that will affect the batt life greatly.

For what it's worth, I've spoken to the team that blogs about the HTC one here : http://blog.htc.com/, and they said the batt life is good, and in that blog, Shane wrote "Even with hours of constant use, the battery held its own. My HTC One X, charged that morning, was more than half full late in the day, despite the heavy use. Indeed, the battery soldiered on though the evening."
[HTC One X] arzbhatia:
My Nexus gives about 41 hours with normal usage, some games, 10 minute music and stuff. The One X will be just fine, a little bad compared to the nexus though.
[HTC One X] fcng:
Please define normal usage. 41 hours standby means you don't make calls or rarely use the phone.
[HTC One X] arzbhatia:
2h - Voice Calls

2 and a half hours - Screen On

GPS/WiFi - Always On

Lucky user :)
[HTC One X] chrisjcks:
Lol don't think so, the Galaxy Nexus is terrible on battery.

Not a single doubt in my mind, to say the HTC ONE X will have better battery life compared to the nexus.
[HTC One X] shure2:
Will i get anything near this?
[HTC One X] crazylilazn:
How is your display % that ridiculously low? You must not be using it. What's the time used by your screen?
[HTC One X] shure2:
See the first screenshot for screen use

You can see screen has been on browsing xda and the internet over wifi or 3g. Brightness is at 40% but it just lasts forever. I do have a new screen, maybe htc put an awesome one in? Lol
[HTC One X] pewpewbangbang:
That's debatable. People with Gummynex can get 5 hours of display time throughout a days usage. But it all varies. I'd say its on par with the SGSII though.

One X battery looks like its all over the place right now lol....with some people getting 2 hours display before dying and some getting 2 hours at around the 50% mark.

And to shure......doesn't help much when you charged it up during battery use
[HTC One X] nativestranger:
I be happy if the onr x can get roughly the same battery life as my sensation xl. I typically have 75% left after 3hrs of screen on time doing heavy browsing. So far it looks like some one x are getting battery low after just 2h 19m.
[HTC One X] pewpewbangbang:
Thats some nice ass hell battery life.....too bad its single core lol
[HTC One X] Sashtheflash:
Here is a dual core one ;)

Sensation at 1.5GHz wifi on ,auto brightness on, syncs on.
[HTC One X] Sashtheflash:
Double post..
[HTC One X] Sashtheflash:
Something went wrong with the second picture can't see it... So here it is again.
[HTC One X] ECrispy:
HTC will no doubt have firmware updates to improve battery life, the device isn't final. At least that's what I'm hoping, some reviewers have mentioned it.

And of course the big unknown is battery life of the One X LTE with S4.
[HTC One X] shure2:
I have no idea why the line has gone up, but the red indicates charging, i let mine nearly compltely die and tgen swap batteries
[HTC One X] schriss:
Sorry but have to disagree. Battery issues were software related.

My Nexus only looses 1% over night with airplane mode on.

My record battery time was 2 days and some. That's obviously with light usage. When using some more, like a call or two a day + lots of music listening + emails + some web browsing, it lats a day and a half easily.

I no longer charge every night as I used to with previous phones.

Now researching HTC One X for battery life as I would expect no less from it. I also wonder how S4 version compares, I kind of like S4 more... but Tegra 3 isn't bad either.
[HTC One X] fi3ry_icy:
just wanna share some battery life stats..

1st power up of the phone.. did a full charge with phone off, once charging light changed to green, i powered up the phone.. 1st thing i notice.. it is not fully charged to 100%..

i rebooted the phone once in between coz the phone felt very hot so im not sure if there was something wrong with it..

all in all, about 3hr+ with high usage of the phone.. notice how the phone was awake most of the time and the screen was on most of the time too..

cheers..
[HTC One X] DomCowell:
Dead images?
[HTC One X] v-b-n:
All I can say from experience and my daily use of iPhone 4S is that it is very comparable to the iPhone (which is performing terrible btw as per its specs, head over to macrumors forums to see ;) )

With mix use and standby I end up with 2% battery loss every hour which is excellent per smartphone standards and should get better and better with proper charging cycles ... Fingers crossed !
[HTC One X] fi3ry_icy:
what does dead images mean? :confused:

do u mean u cant see the images?
[HTC One X] schriss:
You could probably get much more by slightly changing brightness setting or using an app to manage auto-brightness (for example juice defender, where you can set auto-brightness minimum, maximum and average values). 76% of Display seems high to me.
[HTC One X] finduz:
Got my phone yesterday, but I've already charged it a couple of times.

Is it normal for the OS to use so much power?
[HTC One X] jameslfc5:
Couldn't agree more, I have owned around 4 (due to the screen problems) and I never once got more than 3h20m screen on time

It was 3h on average
[HTC One X] nativestranger:
High display % means heavy usage of the phone. The screen was on most of that time. On normals days use with the phone on idle more the display will be closer to 50%.
[HTC One X] chrisjcks:
Yep, the average I've seen was also 3hr which is still slightly less than my SGS2. (both with auto)

I'll never understand people saying it has good battery when it's on standby for most of the time.

I purely & always will judge battery on how much usage I get, not how many hours - heck, i could sleep for 8hrs with airplane mode & still be on 100% in the morning,

But play real racing 2 for

15 mins and already drop to 90%
[HTC One X] schriss:
I understand all that. I still find it great, that I'm connected all the time, up to date with my emails and other stuff, can do calls and listen to music for 6-8 hours a day and the phone still lasts day and a half. I do remember my previous phones were not able to do that.

Many phones suck at standby and I wouldn't want one that does.

Gaming and screen on is another thing, agree that there is lots of room for improvement there. I just know ALL phones suck at that so I never judge by that.

Like my laptop - I know it can last for 6 hours on light use: WiFi+web browsing or (more importantly) working remotely. But I can flip the hybrid graphics switch to enable nvidia GPU and fire up a game and I know there is no chance it would last the same 6 hours.
[HTC One X] xmoo:
Don't know if anyone said this before.

But a spokesman for HTC Germany told me during the CeBit that HTC will give 2 years of warrenty. And that battery was covered in the warrenty. Seeing most people with smartphones only using there phone for max 2 years, shouldn't be a problem
[HTC One X] chrisjcks:
Carphone warehouse state a 24 month warranty on HTC phones, with a 12month battery warranty.

I'm surprised, as most phones I've had in the past are usually only 12months warranty with only 6 months for the battery.
[HTC One X] schriss:
One of the reviews mentioned bad battery life when phone was draining some battery even when idling, then they installed some update from HTC and battery improved by 2x times. Any idea what that update was?
[HTC One X] Zinu:
4.107 instead of 4.102 or something like that. It's currently only available to testers/reviewers.
[HTC One X] MartijnMM:
No, it just means that the screen was on for a long time.
[HTC One X] chrisjcks:
Is that the HTC ONE X?

You have loads of battery left, when you click display, what is your screen on time?
[HTC One X] MartijnMM:
Thats 100% screen time, so 7:45:45

Forgot to turnoff wifi, this is @ 20% brightness (thats what i use)

Here one with 100% brightness, its alot less:
[HTC One X] chrisjcks:
HOLY ****!

my auto brightness on my SGS2 is around 20-30% brightness too! (if i set it to auto off, which is default around 40% - my brightness nearly doubles - so I must be using between 20 & 30%)

But still, 7hrs 45 screen on time, ouch!

Most I've ever got on SGS2 is 3hrs 45mins on auto which seems to be around 20-30%, so if that's true - wow!
[HTC One X] x.Orville.x:
I don't think that its real 7 hours of screen maybe on airplane ??? He have left 68% left on battery
[HTC One X] MartijnMM:
Its with everything off (could name that airplane mode) except

somehow, my wifi was turned on.

Basicly its just to test what brightness does to battery life.....its alot.
[HTC One X] nativestranger:
That was pretty much with screen on but no use of any application running. The excellent battery runtime comfirms that the lcd is pretty efficient and the battery is very good on thr one x. Its only once you start using the phone that the battery drains quickly. Meaning Tegra3 Soc is pretty power hungry. The demo unit i tested went from 100% - 68% in just 36mins of using the browser, market and a few snaps of the camera.
[HTC One X] chrisjcks:
over 7hrs screen on (20% brightness) with over 60% battery remaining - thats insane if true.

I'd like him to do a test from 100-0% with auto brightness :)

I think that would be good information for everyone, especially me as I tend to use auto.
[HTC One X] MartijnMM:
So when comparing battery life, the major factor is the brightness of the screen.

If anyone posts battery stats in a review or whenever, it means nothing

without the brightness of the screen mentioned. Also some devices are

perfect readable when on 20%, but some need 40%.

So its pretty much useless to compare battery stats, the only thing

that matters is how YOU are doing. Is your workspace very bright, then

you need more battery life then someone who works at night in dim light.

For me i can run the device on 20% brightness, so I don't have a problem with

the battery, it lasts a good day for me.
[HTC One X] schriss:
Battery drop when using phone (browsing and so on) might be from radio, not necessairly from SoC. That 5th companion core should be taking care of browsing.

I notice huge difference on my GNex when I play local MP3 or when I listen to internet radio, CPU usage with both is small, but the latter literally kills battery. That's on low H signal, I only have 1 bar here. Good quality H signal tends to drain battery less.

Anyway, if it's radio, it might be improved with future upgrades.

---------- Post added at 02:09 PM ---------- Previous post was at 02:05 PM ----------

EXACTLY.

First, I tweak my auto-brightness to my liking (not too dim, I need to enjoy the phone too!).

Then I test, first in airplane over night to see if battery drop is minimal, like 1-2%, to make sure OS/apps do not misbehave.

Then I use it lightly during day, to see if it lasts 1.5 days. If it does - I'm happy, even if battery drops when I start gaming or using it heavily, like it happenes every now and then.
[HTC One X] nativestranger:
When i tested it was on wifi. Browsing on 3g would be waaaay worse. I am fairly sure the one x would not last more than 2 hours browsing heavy flash webpages on 3g.
[HTC One X] MartijnMM:
Yeah cell radio can take 40% of my HD2 battery stats when not using it.

Still afraid to cut my sim for my HoX :)
[HTC One X] nativestranger:
The HTC One S is reporting extremely good battery life with a much smaller battery. Heavy use on through a 15hr workday with plenty left to spare. And that was on 3G!

HTC One S Review | Android Community
[HTC One X] schriss:
S4 I think is a bit newer tech, it's 28nm, I wouldn't be surprised if it was more power efficient. It kicks ass in CPU performance, I believe it might be the fastest CPU out there at the moment.
[HTC One X] xmoo:
New OTA should make battery a lot better: http://xdaforums.com/showthread.php?t=1579818
[HTC One X] chrisjcks:
The one s gets its ass kicked in Antutu, which is true multi-core compatible.
[HTC One X] schriss:
Yes but UI and most of the apps wouldn't use more than 1 or 2.
[HTC One X] d33f:
Indeed if i may believe mobilecowboys :)
[HTC One X] chrisjcks:
& last year people said the same about dual core phones.

The S4 might be current now, but in 6months - people would be wishing they got the Tegra 3 quad.
[HTC One X] nativestranger:
Indeed. Hard as I tried, I frankly cannot notice any difference in UI or operational speed and between the One X and the single core Sensation XL.
[HTC One X] schriss:
And early benchmarks suggest that S4 is much quicker than Tegra 3 when dealing with single threaded apps/operations. Which won't stop me from getting One X. Just saying.
[HTC One X] atkhobby:
I tried to quesstimate the screen-on based on the graphics shown and it does not look like more than 3 hours+. Does not look like heavy use to me.

Also they had it on the charger for a period in the end.
[HTC One X] rahularora1:
Here are my.current stats:
[HTC One X] nativestranger:
I wont be getting the one s thats for sure. Hate amoled pentile displays. S4 isn't that much better than Tegra3 cores in single threaded but its showing very promising power efficiency so far. However Tegra 3 will far outperform S4 when applications make full use of quadcore. But so far only a few apps have shown to be easily coded for multicore. Mainly video/ photo editing. Quadcore will really catch on when people start to use phones to replace their desktops like watching online videos while converting videos, stitching photos and virus scanning in the background.
[HTC One X] vinfromuk:
That's really impressive - anything better than I get on my Desire (was at 49% with the screen on for maybe an hour today) is fantastic for me though :)
[HTC One X] MartijnMM:
Continues video-playing (720p movie) @ 20% brightness.
[HTC One X] schriss:
From what I saw, S4 was sometimes twice as fast as Tegra 3. But yes, apps and OS will get tweaked for quad cores. And Tegra 3 fares better than S4 non-Pro.

I'm not considering One S at all. I think about something like One X but with S4. But since Tegra 3 is available now, I will most likely get One X and wait for Galaxy S3 or something packing Quad S4 Pro. My last to phones: SGSII and GNex I didn't have them for more than 6 months, and I don't expect to keep One X for more than 6-12 months either.

I'm not worried about One X battery as much as those screen glitches. I remember the time when GNex had terrible battery and then one ROM flash later it became great (at least for me).

But I must say I was hoping for a bit more after reading a lot about that companion core that was supposed to save tons of battery.
[HTC One X] :
What did you do to get this results? Full charge without powering it on as you received it and then...? How should I do a proper calibration the first week? Always discharge all the battery before recharging it? Do these li-polymer (right?) batteries have "memory effects" or can we recharge them when we want?

Thank you for these good news about the battery!
[HTC One X] DomCowell:
Some of these new battery stats are fantastic imo!

Really exciting, probably due to the piss poor battery life I have experienced from my Milestones ****ed battery over the past few months
[HTC One X] schriss:
As far as I know, you treat Li-Poly same way as Li-Ion. It's very similar but Li-Poly basically has more capacity at the same size as Li-Ion, could be due to less internal shape restrictions.
[HTC One X] MartijnMM:
First thing you do is charge to 100%.

Then use it as much as you can.

Try to avoid draining it completely.
[HTC One X] derpious:
This don't matter, the phones have some sort of fail safe so you won't be able to completely drain the battery. Even if the meter shows 0% on the phone there will still be juice in the battery, or it might get seriously damaged.
[HTC One X] eteyen1:
which is what then? How do you go about calibrating it?
[HTC One X] MartijnMM:
Better safe then sorry :D
[HTC One X] schriss:
I think same way: first charge all the way up, disconnect, then use until the phone goes off by itself. If it's not calibrated, the battery meter can lie, so don't trust it at first. It can say 3% left and stay longer like that, that's when it's calibrating. Next time you charge it it should be much more accurate. I think people suggest to do that 1-3 times. Then start using it normally, recharging when needed. Those batteries like to be charged rather than be at discharged state.
[HTC One X] OysterCatcheRR:
This is bad info. You are talking about NIckel Cadmium batteries, where as the One X uses Li-Ion

Lithium-ion is a very clean system and does not need formatting when new, nor does it require the level of maintenance that nickel-based batteries do. The first charge is no different than the fifth or the 50th. Formatting makes little difference because the maximum capacity is available right from the beginning. Nor does a full discharge improve the capacity once faded..

http://batteryuniversity.com/learn/article/how_to_prime_batteries - Really useful site, check it out
[HTC One X] knoxploration:
AFAIK, it's LiPo, not Li-Ion.

---------- Post added at 03:45 PM ---------- Previous post was at 03:45 PM ----------

The charging light doesn't actually indicate a completely fully charge, just a mostly full charge. Leave the charger plugged in a few hours more and it'll top off to 100%.
[HTC One X] OysterCatcheRR:
Same deal with conditioning it
[HTC One X] joschi1985:
My stats, with real heavy facebooking, calling etc...
[HTC One X] schriss:
I'm not talking about formating or conditioning, but calibrating. I do know battery types quite well. I still believe this was a good info, not bad. Doing the procedure the phone and it's software learns battery characteristics. Any battery calibrating software that lets you reset battery stats will ask you to do that procedure. You do it to have accurate battery level information.

I never even knew the capabilities of external batteries, until now, but they seem fantastic! I ordered this 7000mah one from Amazon

http://www.amazon.co.uk/Arcadia-External-Motorola-Blackberry-Nintendo/dp/B004UN3N0W/ref=cm_cr_pr_product_top

And it should give me 3 full recharges, which will be invaluable to me as I go backpacking and climbing quite often and dont get easy access to phone chargers! For day to day use, just keep it in your bag/briefcase, and it shouldn't ever be a problem.
[HTC One X] schriss:
I prefer those that do not need a cable:

Always have one like that in my bag, just a slightly longer version.
[HTC One X] SamStone:
I just bought my One X a week or so ago and while I would have preferred a removable battery, battery life seems good with my One X. About the same as my Sensation XL and much better than the original Sensation. I'm able to get about 1-1/2 days out of the battery with normal usage.
[HTC One X] joshnichols189:
No.. the phone charges to 100%, then goes off the charger down to around 95%, then charges again to 100% so it doesn't overcharge. Leaving it on a few extra hours won't actually do anything as it will just repeat this cycle.
[HTC One X] Born Twitchy:
Image shows 1.27 software, 1.28 should be even better I guess...

[HTC One X] eteyen1:
so what is the definitive answer regarding priming/formatting/calibrating the battery?

ie when I get my htc one x, what should I actually do in terms of battery
[HTC One X] pewpewbangbang:
Use it till it dies, then charge it up to 100%. Should be good to go, but if you want....fully drain again and charge up to 100%.
[HTC One X] joshnichols189:
Use it normally until you need to charge it. It doesn't have to die, then charge overnight or whatever and use until you need to charge it again. You can have normal use from the get go.
[HTC One X] schriss:
The slower the charge the better for battery. On the other hand external charger will most likely have simlar output values as your wall charger. Look for Amps. Usually it's 1amp. Laptops and PCs have 0.5amp. You can buy 2amp charger if you want, I have one, but not intend to use it unless necessary. Faster charge tends to wear the battery quicker.
[HTC One X] OysterCatcheRR:
Hi, I am new to Li-Ion Poly batteries as well, so was wondering the very same thing - but it turns out iphone 4 and 4s use Li-Ion Poly batteries also (which this battery is made for) so it should be absolutely fine.

As schriss says though, I would only charge it from the 1A USB hub, just to be extra safe with your battery health.

I would also check out the 11000mah one by New Trent, especially if you think you could find you are away from a power source for extended periods of time
[HTC One X] Chartist:
What we need is something like a giant spectacle case with an external battery attached and with docking pins inside. You then keep the phone in it in your jacket pocket so that it is always is always fully charged. Anyone going to build it?
