[Q] HTC One X battery life issues, first charge problem or.....?

Hey guys, I just got my HTC One X a few days ago and this is my third day running on this phone.
I wonder if giving it a first charge for 8 hours was needed to condition the battery and giving it as much battery life as possible.. Because when I first received the set, the set was without juice. So I charged it up till about 15% and I received a notification about an FOTA update and I went ahead with it.
After the phone reached slightly over 35%, I let the phone install the FOTA(while still at it's first charge) and it hanged halfway.
I didn't know what was happening so I tried rebooting the device(as removing the battery wasn't possible with the One X). After several tries of holding down the power buttons, I removed the microUSB cable attached to my phone and the phone went blank and it restarted by itself.. Take note that the battery was only at ~30% at that point of time..
And one thing I noticed when the phone didn't respond during the FOTA update was that the AC plug was not as hot as it was used to when charging.. Yeap, so does anyone know if I have actually 'damaged' the battery or maybe it's just the handset that's power hungry? Thanks!
PS, Thank you for taking your time to read this long wall of text and taking your time to reply to my query!

I'm not too sure what the problem is now. Is it about the power draw, or did you brick your phone and wondering if it was caused by a damage battery on your side?

Well, I'm just wondering if me not giving a proper 'first charge' has anything to do with it's poor battery life or it's just natural for the device to be this power hungry, haha.

How much screen on time ate you getting?

You shouldn't charge while flashing the OTA.
I don't think you did any harm.

I haven't been able to get any numbers yet because these few days I've been running the phone mostly plugged into the wall socket. Yeah.

I only had a two hour battery life after the first complete discharge and 8 hour recharge.

Assuming your FOTA Succeed,
Try...
1. disable fast-boot (Settings > Power > Untick fastboot)
2. Power Off
3. Charge (until green / 100%)
4. Power On
5. enable back fast-boot
6. Hopefully you got real battery-stats already

I've noticed some improvement of the battery life of my phone after flashing it with a custom rom.
With a giant screen, a powerful processor, and an elegant packaging, pour battery life is kind of expected, for me I've put chargers almost in every corner of my home, at work, and in my car.

I normally get about 3.5 hours ++ screen time on a full charge, auto brightness.

I am getting 5 hours of on screen time on my stock Rom. Is that possible to get more screen time like 9 hours on custom Rom ?

I didnt charge it when I first got it either. I booted it instantly and used it untill the battery was completety drained and the phone shut down untill I recharged it completely and my battery life is horrible. The worst of any HTC one x so I wonder if I might have damaged the phone aswel??

Charging it when you first get it does nothing. If you have such bad battery life it is probably a faulty phone.

When I first got mine I ran it till it died then did a full charge so that shouldn't matter at all.

My battery was ok on 1.26 then updated to 1.28 and it went beyond awful but after about a week of use on 1.28 my battery has improved a lot... Bought an external charger while was waiting on next update but before I received the charger battery went boss !! So my guess is give it a few days and don't be inpatient with it as it will come around

I'm having issues with my battery life. I'm also new to the Android platform -- well sort of, I've used CM9 on my HP Touchpad for a while now, but this is my first Android handset. I've had the phone for almost a week now, and I've noticed that I barely get around 9 hours of moderate use per charge. On average my on screen time is about 3.5 to 4 hours. That is terrible. My iPhone 4 is lasting twice as long as my HOX and I've had that thing for about 2 years now. Any tips on improving battery life?

[Q] horrible battery problem on ONE X

I know there are loads of threads about the HTC ONE X battery but I really could not find a proper answer to my question so im starting a new thread. So I have had my 1X since last thursday, just over a week now and the battery life has been utterly horrible. But the worst thing is that the battery life is getting drastically shorter and shorter every day. Now its unbearable I cant even use the phone. I wonder if it might be because I did not do any 'first time battery charge'?. I just booted the phone instantly instead because honestly I did not know that you had to charge the battery before booting the phone the first time. The first time I started the phone it had just over 40% of battery and I used it until the phone shut off and charged it 100% after that while it was updating to the newest software. Is this perhaps the reason why the battery life is so god damn horrible and even worse than other 1X's?. When I charge the phone 100% it drains 1% of battery or more every minute now just when browsing the menu or the web or just doing nothing but putting the screen on. The screen brightness setting is on automatic and I have tried all kinds of battery savers and now im using juice defender ultimate still the battery life is horrible. I kill and close apps all the time and have nothing running in the background when not using it and I always turn off wifi when not using and I turn off auto sync and all the other battery eating tasks and stuff. Still I cant use the phone. When its 100% charged at about 8:00 in the morning the battery is done for at around 10:30 with moderate use. I cant get more than about 3 hours of on screen time before the battery is finished so basically what should I do? Is this normal?

And if you'd have read the other threads that you said don't apply to you you'd realize that because your phone is still new battery life will improve with more charging cycles. If you expect more than 3 hours on the low-end or five on the absolute high-end of screen on time the One X isn't for you. Because of the non-replaceable battery (which shouldn't be a surprise) a lot of us have auxiliary battery chargers for getting through the day when the phone can't be topped up on AC power. Speaking for myself, the design of the phone is what attracted me to it and the non-replaceable battery is a trade-off I accepted. That might not be a trade-off everyone’s willing to accept and the One X isn't going to win any battery life awards.

Autobrightness seemed to cause my battery to drain. Turned it off and its much better (or seems that way for now)

Charging your battery when you first get it does absolutely nothing. Wiping battery stats and callibrating also do absolutely nothing.
Sent from my HTC One X using xda premium

Upload few screens of your battery usage so we can see what is causing such drain. I can tell you already now the screen is the main battery drain. A phone can barely survive 4 hours of heavy usage, especially not on automatic brightness.

Yeah ill do that, how do I take a screen shot? Powerbutton + homebutton thing doesn't seem to work for me :S. Today for example iv'e charged the phone 3 times and after the 2nd charge I used to phone for 5 hours and 25m until only a few % of the battery was left. I had juice defender ultimate up and running most of the time and screen time was at around a bit over 2 and a half hours. All I did was some web browsing and mostly menu browsing and setting browsing on the phone and some xda developer browsing with the app. No gaming whatsoever. Really horrible battery... such a pity considering how much I love the phone otherwise. Its no problem when im at home connecting it to the computer with the usb cable all the time but when im actually using the phone outdoors its frustrating as sh*t.

It doesn't really matter what you are doing, you will only get around three hours of screen on time.

Have you tried easy battery saver, started using it on my HOX over 30HRS ago browsing, video calls and still have 33% life left. If it doesn't work I suggest you return for a replacement. Could be factory defect.

Yeah, that was the first one I used, it didn't really help but juicedefender on the other hand helps me squeeze out a bit more battery life

Sounds like a lemon, have it replaced asap. HOX is the only android device I had that gets me through the day w/o charging doing basic stuffs (data always on etc) like what normal people do. I've had sleepless nights last month because my 2-week old GN got pick pocketed battery life for GN in my case was horrible (5 hours).

how do you know if your battery is defective? i'm getting around the same battery life myself :/

This is why unreplaceble batteries suck. I wish I'd bought the s3 instead still though I love the HOX only if the battery was a bit better ffs. Im getting a little bit better battery today but with loads of tweaks, still some 'untweaked' hoxes get better battery lives, still though it seems like there are loads of one x's that have the same issue as I do. Does this mean all one x are different or what?

Batt bad bad bad

I´ve just moved from th GS2 to the HOX and even though I had read reports about the battery not being so good I was really surprised at how bad it is! I mean with the GS2 I would watch about 1 hours of videos, navigate a little bit, check my calendar several times and talk a couple of times and I would get home at the end of the day with about 80% full batt...I do the same with the HOX and it´s almost half that! Plus it takes forever to charge when compared to the GS2, GS1 and the Atrix. Is it really that bad or is my unit faulty? Is there a mod or an update that can probably address this?

If you used to get all of that use out of 20% of your sgs2 battery, you probably had a really good sgs2 because I could never achieve anything like that.
Sent from my HTC One X using Tapatalk 2

So you just got it and reporting a bad battery after a first charge probably? Use it more and report again then...

Well I´ve had several other smartphones that didn´t have this issue after I "just got them".

I think you GS2 is incredible

Cycle the batt
The hox has wayyy better batt life than any samsung
I don't miss the 3% increase an hour it took for any samsung to charge once they are dead forget about getting a fast charge may as well have a spare charged n ready or how about the can not use camera bs!! because the battery is to low... to function the cam
Lol all that crap is history.
Charge the phone with data toggled off
Set screen to 15sec time out
I'm getting 15-16 hrs out of mine on heavy use

I must have faulty unit then because I really don´t see it. I´ve used the GS2 for an year and the battery was supperb. And I had the screen set for maximum light ALL THE TIME.

I came from the SGS2 which was running VillainRom with an underclocked CPU with under volt. (Auto Brightness)
.... and my stock HOX gives better battery life whilst having a much brighter default auto brightness.
Under my usage, I would never get over 3:xxhrs screen on time, so if you used 100% brightness, you can probably half that.
Also regarding streaming (as I do a lot of it), my ex SGS2 would die after around 6hrs whereas the HOX can do 9+hrs, ive tested these thoroughly.
So, I really don't understand this thread.

Remember that you have a li-po battery in the HOX ... you need some charging cycles to get the full performance of the battery

Thanks. I didn´t know that. I will work on it.

HOX= HTC One X ??? how long can batt use??

Well even me coming from the SGS2 I can say it had the better battery life with an extended battery. Could easily get 4-6 screen on time on various things. HOX is fine but not as good as SGS2 with extended battery.
Currently in Turkey on roaming and idle time in this is quite excellent the 5th core works fine in idling.

@liberator 72 - What settings did you have for screen brightness? Was it auto or did you set it manually to a low value? I am asking as I can't get past 3h of screen time, about 10 days after I bought the One X.

Auto brightness. Pretty much standard stock setup with only a few of the bloatware apps disabled in the apps settings and haptic feedback turned off. All accounts setup to auto sync too! It took a good couple weeks for the battery to last that long but now on moderate use I can get 2 days out of it.

If you want to be sure that you don't have a faulty battery you can always perform the HTC test , type *#*#3424#*#* in the phone and look for battery test.

Tried that got the O2 woman.

edit: working. I just have fat fingers.

Not really now
I used to get only 8 hours out of my HOX with it getting extremely hot. But then someone suggested me to perform the following steps in exactly this order.
1. Turn Wifi Off, set sleep mode to "always".
2. Turn 3G data On
3. Turn 3G Data Off
4. Turn WiFi back on
5. Close Maps, Gtalk and any other Google service when not using the same.
I am getting 48 hours on an average with 3 hour screen On time. I am On 1.28 Stock.

2h30 min to fully charge the one x !?

So, is this normal to wait 2h30min and maybe more (!) to fully charge the phone ?
new phone, original charger and original usb cable...

From about 15% mine takes 3 hours

Although my battery bank charges my HOX in less time at 2hrs 35mins

How the hell are you draining in 8hrs - constant use?
Normal days without gaming gets me 17+ hrs
Even streaming all day via data connection gets me more than 8 hours.
I noticed when I got mine, I thought it had low battery as I was always using it, due to the 'ive got a New phone, can't leave it alone bug'
Normal usage, few calls, bit of browsing, bit of gameplay etc should get you through your working day quite easily.

this is what i got last night before i plugged my phone in to charge.
i can easily get through a day without wondering where i can plug in my baby.

i get over a days use with my battery since the last software update... but charging time does seem fast.
is there such a thing as overcharging in terms of degrading battery life?

Please use one of the existing threads on battery life and charging time.
We already have plenty of them and would like to keep everything compact.

Htc One X -battery life

hello everyone, i am new to this community, sorry for my bad english, i would need some help. i have a htc one x for several weeks now, and i have a hudge problem with the battery life on this device, im a really hudge fan of htc, but im dissapointed, so for example, i have 9/10 lines of battery life in my settings menu, i plug it in , and start playing dead space, after 40 mins of playing the battery actually dropped by 2 lines , and i had left 7/10 lines of battery. how is that even possible??! all the phones i had, laptops, etc that require a battery worked in the folowing order: if you plug it in and took the battery out, it still worked, so if you had the battery in, it both keept alive the phone/laptop/every device on the world, while charging the battery, so if you use it, it wont loose power, but gained it. i wached a lot of videos and posts of people explaning hot to get more guice out of htx one x , and some wore like, well , dont use it too much, or do ont turn on your phone to see the clock cause it will save some battery..... ?!?! well i dodn't pay a ton of money to have a phone in my pocket and not be able to see what the time is, or play something/ lisen to music , without actually noticing that in 2-3 hours i wont be able to make a call, yes its a strong phone, and verry good one, by design, by hardware, and software, but the sad thing is the battery, does anyone have a mirracoulous tip for me? and perhaps others as well... (oh and i charged it as ppl from htc told me, first three times with the battery empty for 8 hrs..)

the battery will run out whilst charging, under heavy usage, because the phone is using more power than the charger can provide.
laptop chargers can handle this, simply because the charger provides more power to it. (and the fact laptop batteries tend to be several times the size of the hox)
you should only find that whilst using a battery/cpu intensive task such as navigation (it uses GPS, data sometimes, and the screen is on) that the charger won't be enough, but for most other things, like general web browsing etc, the charger will do it quickly enough
the screen is what takes basically all of the battery, so you can reduce that by making the screen brightness a bit less bright..
the battery life when the screen is off is incredible. WAY better than any other phone i've had. when the screen is off, the phone uses about 1% battery every 2 hours or so. and that was with wifi etc connected and autosync still switched on.
whether the phone will last you all day or not, depends on your usage. if it doesn't, then either make the brightness even lower, or you can purchase a portable charger. or a battery case.
there's no point saying well other phones have better battery life like an iphone. lets be realistic, the iphone DOES NOT have better battery life. it may have had decent standby battery life, but so does tegra 3, probably better than iphone now. when you actually use an iphone, or any other smartphone for that fact, the battery disappears just as quickly as this one does.

Tegra 3 standby is awesome. Just tried an experiment. Please note that this is with 3g or WiFi on all this time and with auto sync.
Again this is just to demonstrate standby time.
For the op, are you sure you don't have a rogue app? Also are you using an HTC charger?

i know stand by is awseome, and i am using the original out of the box charger and cable, but i might go ahead since i know a thing or two about electronics and modify the charger at 2 amps vs 1 amp currently.. this will give me faster charging, but im still researching, cuz i have second toughts
p.s. do you have a costum rom? it doesent look like a prtscreen from htc one x

Unlikely. Unless the phone knows it can draw 2 amps, it has to assume a 1A capable charger (designated by connecting the data pins together).

dude calm down ) lol im a student at mechatronics and robotics, i make robots, and work with voltages and intensity, yeah, normally i don't tweak this kind of things, but a battery does not cach on fire or explode, ony batteries from cars and up, not small ones the worst that could happend is it will heat up, and if let alone, will pour battery acid, wich is not dangerous like car acid , cuz is in a verry small amount and it just needs not to be handled by unprotected hand.
p.s. since im new, cant post alot.....

I used it all 11 hours. Mostly reading second book of Game of Thrones in Kindle app. Checked some net sites, xda forum app, some blogs. Few calls and texts. All the time on wifi. Was sick in bed. Auto brightness, but as my eyes didn't liked strong sun is can say that it was quite dim inside.
But it probably depends on usage. Yesterday I was reading on the beach and I had 4 hours screen on time. Probably brightness all the way up as it was quite hot sunny day.
On normal day I get 4-5 hours screen on time.
Full stock One X.

batteries nowadays can resist pretty much, and unlike a laptop battery that has a chip in it and it records every charge, and then after x charges it suddeny stops working correctely this is cuz of the company chip they insertet to make is useless after x charges, a phone battery is just a normal one, this is tested, i opened a laptop battery and took the chip out, and via com port on pc, i was able to retrive the data storred by the company that produced it, but was not able to reset it, (comsporacy) lol . so i will buy a htc battery, not necesarry one x's and i will test it my charging it a couple o times bowth with the amp maxed, from 1 to 2 (1,1..1,2 etc) and voltage from 5 to 10 V, maby ill get a result, that is a little better than the technique i saw a couple pages away about charging your phone, then powerring it off, charging it again, then pwr on charging it again etc, forgot the method name, but in my opinion bubjecting a rechargable battery to so manny fluctuations of current in so little time does not sound good, my idea of amping the charger or the voltage by just a little sounds a little better in my opinion

You scare the **** out of me. Please don't do this indoors or near any other living creature. You know nothing about charging batteries and are going set your lithium ion battery on fire.
Go check out http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries before you hurt yourself.

dude calm down ) lol im a student at mechatronics and robotics, i make robots, and work with voltages and intensity, yeah, normally i don't tweak this kind of things, but a battery does not cach on fire or explode, ony batteries from cars and up, not small ones the worst that could happend is it will heat up, and if let alone, will pour battery acid, wich is not dangerous like car acid , cuz is in a verry small amount and it just needs not to be handled by unprotected hand.
p.s. since im new, cant post alot.....

you have a lot to learn then.. Batteries can explode, and they do: here's a video of some guys iphone setting on fire in his back pocket, turned out to be the battery that caused it.

That isn't my pure reasoning behind my thoughts anyways, whatever experiments you do with higher amp chargers won't do anything, because the phone won't accept more charge than the circuitry allows. Which happens to be a safe amount for the battery. This is so the battery doesn't get damaged, and in some circumstances, set on fire or explode.
If you take the battery out and start prodding things at it and take it over its limits, be prepared for fire or explosion. Like Ben said, put yourself and only yourself at risk if you choose to do it.. And be wise and have a fire extinguisher ready.

Battery life on ViperX 2.6.0
nutzaalex said:
hello everyone, i am new to this community, sorry for my bad english, i would need some help. i have a htc one x for several weeks now, and i have a hudge problem with the battery life on this device, im a really hudge fan of htc, but im dissapointed, so for example, i have 9/10 lines of battery life in my settings menu, i plug it in , and start playing dead space, after 40 mins of playing the battery actually dropped by 2 lines , and i had left 7/10 lines of battery. how is that even possible??! all the phones i had, laptops, etc that require a battery worked in the folowing order: if you plug it in and took the battery out, it still worked, so if you had the battery in, it both keept alive the phone/laptop/every device on the world, while charging the battery, so if you use it, it wont loose power, but gained it. i wached a lot of videos and posts of people explaning hot to get more guice out of htx one x , and some wore like, well , dont use it too much, or do ont turn on your phone to see the clock cause it will save some battery..... ?!?! well i dodn't pay a ton of money to have a phone in my pocket and not be able to see what the time is, or play something/ lisen to music , without actually noticing that in 2-3 hours i wont be able to make a call, yes its a strong phone, and verry good one, by design, by hardware, and software, but the sad thing is the battery, does anyone have a mirracoulous tip for me? and perhaps others as well... (oh and i charged it as ppl from htc told me, first three times with the battery empty for 8 hrs..)

I've been having the same issue as well. The stock ROM on HTC one X drains the battery rapidly. For me, In normal day which includes listening to music, playing games, browsing and making calls, my battery would last maximum up to 20 hours; meaning that every night when I go to bed I had to charge it for the next day.
This problem was battling me a lot. I learned that the stock ROM is taking advantage of all (4) CPU's and memory even while in idle. The whole battery consumption relies on the CPU usage and Memory management.
I moved to a custom ROM called ViperX 2.6.0. I'm very satisfied with the result. It seams that they've managed the CPU and memory in a very good and neat way. The ROM has a lot of tweaks.By default, when installing the fresh ROM and wiping the battery stat, the battery would last one and half a day. By doing a number of simple tweaks such as disabling the animations on transitions, disable fast dormancy and disable smart sync you can have the battery up to two days.
Check the attachment, it's a screen shot of my battery usage.
Hope this helps.

How the hell are you getting this much screen time ?!
I dim the screen to the lowest brightness and disable
sync and sometimes in flight mode, and I can hardly get
3h of screen time! I mostly read on it, so it shouldn't
be battery intensive.
oh, and If I use it outside it lasts even less 2-2.5h.
What's your secret?
Oh and I use the latest CM10, and downclock my
cpu to 800-1000mhz

Then your phone is knackered.
I can get 4+hrs screen on time with auto brightness, auto sync, stock cpu levels with wifi on.
That's no secret, that's just what it does.
As for 'just reading' - you can easily get over 13hrs screen on time with lowest brightness & flight mode - I've tested it myself on the Kindle app.

AOSP roms get much less battery life than Sense roms, 3hrs screen on time is about average.
I'm currently running CM10 with Neo kernel 7.2 @ 1.3GHz and getting almost 4hrs screen on time. With Faux kernel it was usually around 3hrs.

Chrisjcks, what do u mean by "your phone is knackered"?!
Its a new phone! I just got it 2 weeks ago.
Michealtbh, it may be somthing with the APOP rom, but I really
hate using sense ... I want to try this Neo Karnel first,
Can I just flash it on my cm10? (without wipe)
Where can I get it?
How do I know which kernel is im my current rom?

Your phone is fine.
You can find it here http://forum.xda-developers.com/showthread.php?t=1873615
You have to flash the boot.img through fastboot then the modules in recovery. You're probably using CM10 kernel atm

Ok, but don't moan of battery if you are running a beta (alpha) custom rom.
The HTC ONE X battery is fine, especially after the sense 4.1/4.0.4 upgrade from 2.17

Michealtbh, Thanks!
I'll try that soon. (it's stable, right?)
I'm now testing the new Nightly.. it's real good and battery life,
seems promising, looks like I'll get 3.5-4h of screen time there
(No sync with low brightness though)
chrisjcks, I'm not using alpha roms, just the stable ones.
and this DOES feel very bad battery life to me, I come to the hox
from Motorola milestone, and there I could easily get 7-8 hours
of screen time with wifi. (and it has smaller battery and 40% overclocked!!)
How much do you get on the new stock?
When I was on stock i remember it ran out after half a day,
only using it for music and taking some videos.

Battery life varies a lot. On stock in London I get a full day screen time of around 2-3 hours with 3G on all the time. Which for me is fine.
Last weekend I was in Portsmouth and the signal was very patchy and my phone died within 10 hours. Hardly any screen on time.
So it does really depend and will vary for user to user depending on your signal and how the phone is set up.
Mine is usually on auto brightness, and auto syncing on.
Today I've been at home as I've got a damn cold but my screen on time is over 4 hours in good signal and wifi. Same setup. So you can gather from this that signal, data used, etc can affect battery life in many ways.
