My Galaxy Nexus with 1750mah battery, roughly the same size screen (4.65"), also 720p but different screen tech lasted about 3h10m screen on time on average :/

Which was obviously poor, but there are lots of factors that will affect this HTC, eg better processor (with companion core), Super LCD 2 might be more energy efficient plus HTC software should hopefully result in better battery but I'm not holding out for anymore than 4 hour screen on time tbh
[HTC One X] jameslfc5:
Also as far as lasting the length of the contract goes, according to their website carphone warehouse offer 24 month warranty for the phone, 12 for accessories and battery.

So if it was to get worse you'd be able to send it off for repair and they'd probably just replace as I doubt they'd be able to fix it with it being unibody.
[HTC One X] DomCowell:
Hmm, going to change settings on my Milestone to see what battery life I get out of that without touching it (screen on). I would be disappointed with 4 hours screen time to be fair.

Did you forget to type the rest here, or have I misunderstood :) Thanks for the first post!
[HTC One X] jameslfc5:
My time on the Nexus was mainly spent browsing the internet or streaming music tbf so that wouldn't of helped as it was all happening over 3G
[HTC One X] AllEyezOnMe:
Has anybody noticed that the one x will hav an li-polymer battery as opposed to the usual li-ion do what kind of impact is this going to have?
[HTC One X] hpacura:
+1

This concerns me the most as well (the other is no micro SD slot but I can live with 26gb storage better then the galaxy nexus) and holding me back from pre-ordering it. Wonder the logic behind of having non-removable battery on such a nice phone? *** sign *** sign ***
[HTC One X] jameslfc5:
I've noticed since my iPhone 4 had it, and I presume only a good impact like faster charging and no memory :)
[HTC One X] w1nter456:
Truth be told, the reason I did not buy Galaxy Nexus was because the poor battery life and 16GB storage. If you go to gsmerana.com and find the galaxy nexus battery result, you'd be suprise because GN is MOST worst battery life test expecially in web browsing roughly survive 3 hour in GSM model.

This one don't worry about it. In my research, I found out that when on idle, HTC One X will use the fifth core to save battery life. Whenever you watch video(this one most benefit to me :D), it's up to 60% of power saving using 4 cores which is 12 hours. The lack of mirco SD card also helped to improve performance and battery life since don't require additional card reading. 4 cores actually increase performance while increase battery life when browsing, gaming, video and others.
[HTC One X] DomCowell:
I too wonder this. I guess the overall finish looks slightly better without a removable back cover. The lack of the MicroSD slot is not a big deal for me, simply because of the good amount of internal storage - and the 25gb Dropbox storage that comes included. I am trying to hold out from pre-ordering, with the (bleak) hope of seeing the Galaxy S3 event announced before the 5th of April. I guess the majority of deals available will still be available after the release.

Another problem for me, is HTC's habit of releasing an unnecessary number of phones a year, compared to the S series which is an annual flagship affair. Having said that, I have never been a fan of the "Home" button on the S3 - but that wouldn't stop me buying it if it topped the One X on the majority of key features (erm, a removable battery for a start?)
[HTC One X] w1nter456:
Actually I see no point of having removable battery cover because when you dropped a phone, the phone will actually break out..battery cover, battery and even worst SIM-card. My father has damaged his phone because of constantly dropping phone and I have to repair it piece by piece. About your second problem, don't worry about it. HTC already stated that they will focus on "Quality" not "Quantity". That is why you saw One-series were based on this idea. ;)
[HTC One X] DomCowell:
The sim card wouldn't fall out if it is kept in the place it is now. The issue is the battery is really small (at first glance) for such a powerful phone, and if you can't even carry a spare..
[HTC One X] mhbr12742:
I have had most HTC phones in the last 3 years. I have never had to use my spare.

What i do have though is my small APC portable battery pack
[HTC One X] DomCowell:
Your previous phones weren't anything like as "spec'd up" as the One X though, which is my fear.
[HTC One X] jonas2295:
But they didn't have tegra 3 with companion core etc...

We can speculate about the battery life as long as we can.. We will know it when some people have their hands on.. Not anytime sooner :/
[HTC One X] fzc:
well im on galaxy s2 right now.. love the idea of htc one x in my hands in couple of weeks.. only concern is battery.. im not happy with my gs2,s battery life.. wonder if 4.7 lcd 2 and 1800mah would do any better :S.. keeping my fingers crossed and hoping for best..
[HTC One X] bubigrega:
I don't fear about battery life on tegra 3. Its perfect on my ATP. Companion core actually works great. Usually it only loses 1% of battery over night.

And 32GB should be enough for me.
[HTC One X] jonas2295:
Thanks :) took a bit of my own fear away...
[HTC One X] chrisjcks:
Try to compare with Galaxy nexus regarding battery..

HTC one x has,

- larger battery

- SLCD2, which uses less power over amoled

- tegra 3 has companion core too

So, to compare to the latest nexus, the ONE X should offer much better battery.

..... So, cant be too bad.
[HTC One X] eeeeeee:
1% over night with the atp? with or without doc?

That would mean, since the htc one x has 1800mah, and the transformer has 6930mah, that we lose 3-4% over night, which is pretty good.
[HTC One X] scpion:
Anyone using current widget to log the battery use? I am getting a whopping 1900ma on standby with Wi-Fi on and auto sync gmail account. While using the phone, it jumps to over 4000ma. And no, I did not make a mistake on putting in extra zeros.. anyone can help to verify this?
[HTC One X] Basil3:
Does current widget work with quad core? I know most of those apps couldn't even accurately measure battery drain on dual core devices.
[HTC One X] WhiteHartMart:
First charge and I'm finding the battery to be pretty impressive to be honest.

Was down to 66% battery last night with 1hr 55mins screen time. That's with sync on and WiFi sleep policy set to 'never while plugged in'.

Left all the settings the same overnight except putting it in silent mode and still have 61% 8.5 hours later. Wonder if Smart Sync is helping with that as overnight that's a better performance than my SGS2 with custom Rom :)
[HTC One X] eteyen1:
Sorry to hammer the point, but you said they should not often be allowed to run low for max life, but then you said they need to be run down regularly to avoid them forgetting some cells. So how often are we talking about running them low to maintain such a balance?

:eek: and how did you do your first two charges with the phone then ie charge to full, use till died, charged again or what?
[HTC One X] scpion:
Honestly, I have no idea.. my battery simply sucks.. this morning after unplug after 8 hrs of charging.. i went back to sleep and 2hrs later, my batt dropped by 20%..
[HTC One X] Basil3:
Sounds like an app doing the damage there, just gotta figure out which one!

My current stats after first full charge, is 8 hours on battery, 50% battery left and 2:15 screen on time.
[HTC One X] H-Cim:
Before you judge the battery take the following stuff into account :

1. It takes about 5 charges before your battery is using it full capacity

2. The 5th core of the HTC One X makes the phone use almost no battery in idle (considering your phone is at least half the time in idle -> This is a big deal!)

3. There a lot of battery issues related to the software bugs, the next update (which should be today?) will fix a lot of those already.

I've read that letting your battery drop to 1-10 % is the worst thing to do for this kind of battery! Little parts of the battery literally stop working if they go below a certain voltage (when you have 0 % battery left your battery still has power in it, but software makes it impossible to use the device to protect it from going to very low voltages).

I'd say you better just charge your device every night no matter how full it still is, don't let it drop to low % on purpose!
[HTC One X] Chartist:
I'm sorry if if I was not clear. I said Li ion batteries 'have a 'memory' and need to be run down regularly or else they 'forget' some of their cells.' We do NOT have a Li ion battery.

We have newer Li Po batteries which do NOT have a 'memory' effect and should NOT very often be allowed to fully discharge as this will reduce their life. Our sort of batter will last longer with frequent top ups.

From what I have read all batteries are quoted as having a life of so many 100 top ups. What counts as a unit of top up on a Li Po battery is not the number of separate times it is plugged into the charger but the total amount of charge it receives. In other words, if you fully discharge a battery and then top it up that is equivalent to one charge. If you top up a battery twice when it is 50% charged that will also be equivalent to one full charge.

I am not an expert but I have been doing a lot of Googling. I am still not sure if the battery needs to be fully charged and then completely discharged for the first few days. I don't think this is necessary but as it will do the battery no harm it is probably better to do it. The lifetime of the battery will only begin suffer if you decide to fully discharge the battery on a regular basis. I do not know by how much this shortens the life. Even so, the phone will prevent from taking out all the charge which would do it immediate harm.
[HTC One X] Spl4tt:
oh man..

everyone says different things about batteries. and you now say Li-Ion have a memory effect..

thats not true, you mistake the li-ion with old nimh batteries :P

Li-Po is practically the same as Li-Ion, it's just a newer variant of Li-Ion!

Li-Po allows the manufacturer to shape the battery as they want, so they can design it to perfectly fit the phone's form

that's the only real difference from Li-Ion! plus they can't get as much capacity as Li-Ion with the same size, but that doesn't really matter with capacities around 2000mAh.

but like i said, everyone says other things about batteries.

best you go and try it out. but fact is, that the Li-Po is the same as Li-Ion, just a newer variant with newer technology.
[HTC One X] schriss:
That's what I get from my average usage from my Galaxy Nexus. This also means I'm not charging it every night, more like every 1.5 days. Which in the end means fewer charge cycles.

Don't ruin experience by enforcing some charging/discharging rules. Just use your phones and charge whenever you want, they will easily last over a year or more regardless of our charging habbits. Some people prefer to always top up, others prefer to charge when it's below 50% or even less. If you stop recharging often, you might be surprised how long will that last 25% of battery last and that will set you free from constantly trying to find a cable/charger.

Especially is properly configured phone going airplane mode over night only looses 1-3% during the night.
[HTC One X] Foggy79:
I'm not realy having issues with the battery.

It is fully charged 3 times now and with normal use it lasts a day and a half before it reached 15% and I plug it in again.

3G, WiFi, BT and sync is on (with a shedule)

The 5th core uses 1% over night (8h).

I'm on the first software version 1.26 so with the upgrade comming everything will even last longer.
[HTC One X] H-Cim:
Hey fellow Belgian!

The battery life in idle is insanely good, it makes up for the battery it uses when being used. I expect the 1.27 update to be released tomorrow or monday. That should make the battery perfect.
[HTC One X] schriss:
Yep, I said that few posts ago. People pay too much attention to that Li-Poly thing. It's not different from Li-Ion from user perspective and that's all we care about. We should use Li-Poly in exactly same way as Li-Ion. The only thing I try to avoid is to keep my phone on very low charge (lets say below 20%) for longer period of time. Other than that, I have my own habbits but you can basically do what you want, charge whenever you want. Battery will wear sooner or later, but I don't think it would happen in the first 1-2 years of use.

My phone will be gone in 6 months or so anyway.
[HTC One X] iggy27707:
By "use" do you mean you also made calls and during that 2 hours of screen time use the apps of your choice as well? If so, that's pretty good and would be enough to convince me to buy the phone.
[HTC One X] Arthur Hucksake:
With an 1800mah battery we should get atleast 4 hrs screen time, Sensation with Anker battery 1900mah (So really about 1700 - 1750) I could no sweat.

So much for all the touted power savings of the newer screen and Tegra, what an absolute myth.
[HTC One X] Ruudfood:
I don't think it's a myth. You have to remember that with any device the component that consumes the most power is the screen (specifically the backlight) and the more pixels you cram in the more power will be required. The Tegra with, say, a 800x480 display might give you 2 full days. In my opinion a day is completely acceptable and 1.5 days is beyond expectation.

If you want more power, a bigger, better display, and more functionality then there's always going to be a trade-off.
[HTC One X] Arthur Hucksake:
For a non removable battery, which is 1800mah, i'm finding I get less than half than the battery life I had with the iPhone 4. Just no reason for it.

I hope 1.27 software sorts it out.
[HTC One X] Ruudfood:
Well there obviously IS a reason for it.
[HTC One X] Spl4tt:
every phone can last over a day with only 2h screen on time.

i'm playing games when im in train or in school, or when i'm waiting at the trainstation... screenon time then bumps up, + those games like shadow gun will waste even more battery...

somehow, i don't see a point in buying a new phone, then doing fewer things with it, than with my HD2, just cause i have 2 batteries now..

i can just hope.
[HTC One X] OysterCatcheRR:
Just get an external battery for like 20 quid
[HTC One X] Spl4tt:
it's just not the same, but it's an option, yeah
[HTC One X] OysterCatcheRR:
For me it is a lot better. I got an 11,000mah one that should charge the One X SIX times before running out of juice.

THat is like a week's worth of charging right there and it weighs like 300g
[HTC One X] Spl4tt:
It's not better for someone like me. I'm skating in summer, and i hate carrying a backpack or something. i just put a second battery for the phone in my wallet, and go.

that way i have my phone online for the whole weekend, and even longer x)

1. i don't want to carry something around me bigger than a battery

2. one recharge needs an hour or something, a secondary battery is INSTA 100%

but sure, an external charger is nice, and it's the only option now
[HTC One X] twistedh:
These are mine so far, first day of general use at 50% brightness:

Sorry if the pics won't show. Xda app giving me grief! But I'm at 1% now after 11 hours of general use
[HTC One X] williamyi:
You are not alone mate, I not sure if there is the incompatibility of CW with quadcore or wat, but I'm getting almost the same reading as yours

I hardly use my phone till dead, normally I will charge it when it goes below 10% - 3%..I never unplug it when the LED turns green. Since the day of using DHD, I always unplug the device from the charger when the current widget shows 0mAh, which means the battery is no longer receiving current

My usages on the phone are heavily on Whatsapp, SMS, & LINE messaging, some random FB checking, 3 - 5 calls where each call about 5minutes, a few net browsing and downloading apps fr the play store
[HTC One X] xmoo:
The Idle is just amazing. My SGS2 would drop 6 to 8% every hour just doing nothing but being connected and the phone syncing.

Check this out:

No root, just disabled some apps.

It's syncing Fbook, Whatsapp, Gtalk, Viber, 3 Exchange (push), 2 Imap (1 hour), Twitter (1 hour), Stock (1 hour), Weather (1 hour).
[HTC One X] Arthur Hucksake:
Just got off the phone to HTC. I rang to talk about whether my poor battery life was a fault.

Told me to do the following test.

Charge up to 100%, set the phone to airplane mode, set display to never turn off and put screen brightness to 100%.

Leave the phone for half an hour. If it is below 85% , then it's a hardware problem.

Just charging up to 100% now. If it goes below an acceptable level, im sending the phone back.

A phone has to be close to perfect as possible for the amount I paid. (Sim free)
[HTC One X] Ruudfood:
I think some people set their expectations WAY too high!
[HTC One X] Arthur Hucksake:
Expecting the battery to last longer than the Sensation is expecting too much? :confused:

If your going to ship a device with a non replaceable battery, it needs to atleast be able to last a day with moderate usage.

As shipped.... it doesn't.
[HTC One X] willexmen:
When i got the phone i did a charge, until the LED turned green. Took about 3.5 hours. Couldn't wait any longer and started using it and tryed all the features, tryed the camera and used some heavy application for a while. Not too long though.

After 3 hours i had 20% left, and even if i just scrolled, gently used the phone i could see the percantage going down.

Second charge, whole night. About 7 hours. Today i got 3.5 hours again til it reached 20%, this time less used but with about 55 minutes of listening to streamed music. All syncs was off, screen at 60%. Wifi off.

I mean, it not good. I had the same problem with my desire, and thought that i didn't fully charge it the first time. But everyone is telling me that dosent matter on new phones.

How come the battery time is so different for everyone? What can i do?. Right now it's charging again, had to charge it in school too.

I remember there was a battery trick for Desire and other phones. Where you charged it off, then on and then off again. Should i try that?
[HTC One X] Arthur Hucksake:
Same problem here.

Once people quit riding HTC's sausage and acknowledge the problem, it might get resolved.

We can only hope 1.27 / 1.28 comes out ASAP.
[HTC One X] pewpewbangbang:
You can try, that was the calibration trick for most phones recently. It may help a bit, but it also needed you to wipe battery stats in CWM.
[HTC One X] Arthur Hucksake:
Calibration tricks don't work with these types of battery. Wiping stats and the rest of it will make no difference.

Ugh... I really don't want to go back to an iPhone, but it might be the only solution here. Only phones which seem to have a half decent battery life.
[HTC One X] Ruudfood:
Maybe I wasn't referring to you...!

But since you mention it, I don't know because I don't own a Sensation. But the devices have different capabilities. Use a device with 4 CPUs, a bigger screen, more pixels, etc. and the battery is not going to last that long if you're streaming music over a 3G+ connection with the volume up (for example).

If the tech is not there to make the battery last longer, either by fitting a bigger battery, battery chemistry or whatever other options there are, then the tech is not there. If it was then manufacturers would routinely give you a battery in a slim device that lasted 3 days, 3 weeks or whatever. So that gives you a clue!

It really is as simple as that. Deal with it. Find an alternative solution (another phone with a bit of luck). Just please don't moan because things don't work to your expectations.
[HTC One X] Basil3:
This is like deja vu all over again. Every phone that comes out has people moaning about battery life.

If you are a power user, buy an external power source. They're not very big, and hold way more than one charge. I had a second battery on my sensation but found switching it a pain in the arse, as well as always making sure each battery is always full.

The battery will always cater for 95% of people, I mean how many people are away from a power source for over a day and yet are managing to play on their phones for hours?
[HTC One X] Arthur Hucksake:
Getting a maximum 3hrs use out of a single charge isn't suited to ANYONE'S expectations unless they are a dullard or have suffered a brain injury.

If you have one of these, and you seem like a sensible person, it will get to you in no time.

I owned the Desire and Sensation previously and this has by far the worst battery life of the bunch. That doesn't add up. It's either a software problem, hardware problem or the device just isn't fit for purpose.

---------- Post added at 04:01 PM ---------- Previous post was at 03:58 PM ----------

For £500 , you would expect a phone to be able to make calls here and there, send texts, take the odd photo and maybe look up something on Google Maps get home after work and not expect the phone to die on the bus ride back.

This is nothing like the issues faced with the Sensation on launch, i'm talking 50% capacity and life on the LAUNCH Sensation. It really is that poor.
[HTC One X] willexmen:
That what i want to know. Is it a hardware problem or is it just me having a different opinion on "moderate" use. I can always see people, friends with same phone and have much better battery life. But i can never figure out why. I mean, it can't be hardware problem, very unlikely, they are made in factories and not handmade by people who let say puts a popcorn inside some of the phones. They are all the same, so it must be something with charging the battery different that causes good or bad battery. My other quess is that different 3G networks takes more energy than others.

I'm going to try it out tomorrorow, which is my third charge. HOPEFULLY my battery life will increase when i charged it for the fifth time.

Right now it's charging, should i let it charge til the led turns green or "full" charge, about 8 hours?

It's so darn hard to not look at the screen and scroll a few times, i just want to play with my baby :(
[HTC One X] Basil3:
Strange. I had DHD and Sensation, this has much better battery life for me out of the box.
[HTC One X] Arthur Hucksake:
iP4 has the same type of battery, the general rule of thumb with those is to just charge to green. Use it, and it's better to not let it run down every use. They do advise to run the phone down and recharge fully once every month or two though.
[HTC One X] Superpiper1972:
Why on earth by a Power hungry phone like the One-x and then complain about battery life?

:?

In mobile devices, power is everything (you should go and watch Apollo 13 btw)

So, if you want a phone to last a month between charges, go and buy a Nokia 6310. If you want a mobile computer, don't expect the battery to last as long.

The large, cutting edge phones like these are not designed to be used solely of the battery. Its an impossible feat.
[HTC One X] Arthur Hucksake:
The battery provided should be adequate for the job in hand. "Lightweight" Sense 4 consumes more battery life than Sense 3 for no real reason. How can you remove visible function but increase power usage? lol

It's nothing to do with the battery size. 1800mah is sufficient, there is nothing else drastically wrong here.

Sending a few texts should not kill off the battery, I don't think that is asking too much. If I were playing games and watching movies then sure, I get it.

Wondering if it's down to the Tegra 3 being a POS. Phone does get toasty by doing extreme tasks like make calls.

Flagship phone with lots of new features that your not meant to even use.
[HTC One X] willexmen:
Maybe because NVIDIA AND HTC say that the so called "fifth core" is supposed to be much less power consuming? If a company claim that a phone isn't more power consuming that other phones on the market and Tegra 3 is supposed to be the less power consuming on the market.

Yes, that why people expect better than 3 hours!
